Treas. Reg. § 1.414(v)-1 — Catch-up contributions.

(b) Elective deferrals that exceed an applicable limit

(1) Applicable limits. An applicable limit for purposes of determining catch-up contributions for a catch-up eligible participant is any of the following:

(i) Statutory limit. A statutory limit is a limit on elective deferrals or annual additions permitted to be made (without regard to section 414(v) and this section) with respect to an employee for a year provided in section 401(a)(30), 402(h), 403(b), 408, 415(c), or 457(b)(2) (without regard to section 457(b)(3)), as applicable.

(ii) Employer-provided limit. An employer-provided limit is any limit on the elective deferrals an employee is permitted to make (without regard to section 414(v) and this section) that is contained in the terms of the plan, but which is not required under the Internal Revenue Code. Thus, for example, if, in accordance with the terms of the plan, highly compensated employees are limited to a deferral percentage of 10% of compensation, this limit is an employer-provided limit that is an applicable limit with respect to the highly compensated employees.

(iii) Actual deferral percentage (ADP) limit. In the case of a section 401(k) plan that would fail the ADP test of section 401(k)(3) if it did not correct under section 401(k)(8), the ADP limit is the highest amount of elective deferrals that can be retained in the plan by any highly compensated employee under the rules of section 401(k)(8)(C) (without regard to paragraph (d)(2)(iii) of this section). In the case of a simplified employee pension (SEP) with a salary reduction arrangement (within the meaning of section 408(k)(6)) that would fail the requirements of section 408(k)(6)(A)(iii) if it did not correct in accordance with section 408(k)(6)(C), the ADP limit is the highest amount of elective deferrals that can be made by any highly compensated employee under the rules of section 408(k)(6) (without regard to paragraph (d)(2)(iii) of this section).

(2) Contributions in excess of applicable limit

(i) Plan year limits

(A) General rule. Except as provided in paragraph (b)(2)(ii) of this section, the amount of elective deferrals in excess of an applicable limit is determined as of the end of the plan year by comparing the total elective deferrals for the plan year with the applicable limit for the plan year. In addition, except as provided in paragraph (b)(2)(i)(B) of this section, in the case of a plan that provides for separate employer-provided limits on elective deferrals for separate portions of plan compensation within the plan year, the applicable limit for the plan year is the sum of the dollar amounts of the limits for the separate portions. For example, if a plan sets a deferral percentage limit for each payroll period, the applicable limit for the plan year is the sum of the dollar amounts of the limits for the payroll periods.

(B) Alternative method for determining employer-provided limit —(1) General rule. If the plan limits elective deferrals for separate portions of the plan year, then, solely for purposes of determining the amount that is in excess of an employer-provided limit, the plan is permitted to provide that the applicable limit for the plan year is the product of the employee's plan year compensation and the time-weighted average of the deferral percentage limits, rather than determining the employer-provided limit as the sum of the limits for the separate portions of the year. Thus, for example, if, in accordance with the terms of the plan, highly compensated employees are limited to 8% of compensation during the first half of the plan year and 10% of compensation for the second half of the plan year, the plan is permitted to provide that the applicable limit for a highly compensated employee is 9% of the employee's plan year compensation.

(2) Alternative definition of compensation permitted. A plan using the alternative method in this paragraph (b)(2)(i)(B) is permitted to provide that the applicable limit for the plan year is determined as the product of the catch-up eligible participant's compensation used for purposes of the ADP test and the time-weighted average of the deferral percentage limits. The alternative calculation in this paragraph (b)(2)(i)(B)(2) is available regardless of whether the deferral percentage limits change during the plan year.

(ii) Other year limit. In the case of an applicable limit that is applied on the basis of a year other than the plan year (e.g., the calendar-year limit on elective deferrals under section 401(a)(30)), the determination of whether elective deferrals are in excess of the applicable limit is made on the basis of such other year.

(1) General rule. Elective deferrals with respect to a catch-up eligible participant in excess of an applicable limit under paragraph (b) of this section are treated as catch-up contributions under this section as of a date within a taxable year only to the extent that such elective deferrals do not exceed the catch-up contribution limit described in paragraphs (c)(1) and (2) of this section, reduced by elective deferrals previously treated as catch-up contributions for the taxable year, determined in accordance with paragraph (c)(3) of this section. The catch-up contribution limit for a taxable year is generally the applicable dollar catch-up limit for such taxable year, as set forth in paragraph (c)(2) of this section. However, an elective deferral is not treated as a catch-up contribution to the extent that the elective deferral, when added to all other elective deferrals for the taxable year under any applicable employer plan of the employer, exceeds the participant's compensation (determined in accordance with section 415(c)(3)) for the taxable year. See also paragraph (f) of this section for special rules for employees who participate in more than one applicable employer plan maintained by the employer.

(2) Applicable dollar catch-up limit

(i) In general. The applicable dollar catch-up limit for an applicable employer plan, other than a plan described in section 401(k)(11) or 408(p), is determined under the following table:

For taxable years beginning in	Applicable dollar catch-up limit
2002	$1,000
2003	2,000
2004	3,000
2005	4,000
2006	5,000

(ii) SIMPLE plans. The applicable dollar catch-up limit for a SIMPLE 401(k) plan described in section 401(k)(11) or a SIMPLE IRA plan as described in section 408(p) is determined under the following table:

For taxable years beginning in	Applicable dollar catch-up limit
2002	$ 500
2003	1,000
2004	1,500
2005	2,000
2006	2,500

(iii) Cost of living adjustments. For taxable years beginning after 2006, the applicable dollar catch-up limit is the applicable dollar catch-up limit for 2006 described in paragraph (c)(2)(i) or (ii) of this section increased at the same time and in the same manner as adjustments under section 415(d), except that the base period shall be the calendar quarter beginning July 1, 2005, and any increase that is not a multiple of $500 shall be rounded to the next lower multiple of $500.

(3) Timing rules. For purposes of determining the maximum amount of permitted catch-up contributions for a catch-up eligible participant, the determination of whether an elective deferral is a catch-up contribution is made as of the last day of the plan year (or in the case of section 415, as of the last day of the limitation year), except that, with respect to elective deferrals in excess of an applicable limit that is tested on the basis of the taxable year or calendar year (e.g., the section 401(a)(30) limit on elective deferrals), the determination of whether such elective deferrals are treated as catch-up contributions is made at the time they are deferred.

(d) Treatment of catch-up contributions

(1) Contributions not taken into account for certain limits. Catch-up contributions are not taken into account in applying the limits of section 401(a)(30), 402(h), 403(b), 408, 415(c), or 457(b)(2) (determined without regard to section 457(b)(3)) to other contributions or benefits under an applicable employer plan or any other plan of the employer.

(2) Contributions not taken into account in application of ADP test

(i) Calculation of ADR. Elective deferrals that are treated as catch-up contributions pursuant to paragraph (c) of this section with respect to a section 401(k) plan because they exceed a statutory or employer-provided limit described in paragraph (b)(1)(i) or (ii) of this section, respectively, are subtracted from the catch-up eligible participant's elective deferrals for the plan year for purposes of determining the actual deferral ratio (ADR) (as defined in regulations under section 401(k)) of a catch-up eligible participant. Similarly, elective deferrals that are treated as catch-up contributions pursuant to paragraph (c) of this section with respect to a SEP because they exceed a statutory or employer-provided limit described in paragraph (b)(1)(i) or (ii) of this section, respectively, are subtracted from the catch-up eligible participant's elective deferrals for the plan year for purposes of determining the deferral percentage under section 408(k)(6)(D) of a catch-up eligible participant.

(ii) Adjustment of elective deferrals for correction purposes. For purposes of the correction of excess contributions in accordance with section 401(k)(8)(C), elective deferrals under the plan treated as catch-up contributions for the plan year and not taken into account in the ADP test under paragraph (d)(2)(i) of this section are subtracted from the catch-up eligible participant's elective deferrals under the plan for the plan year.

(iii) Excess contributions treated as catch-up contributions. A section 401(k) plan that satisfies the ADP test of section 401(k)(3) through correction under section 401(k)(8) must retain any elective deferrals that are treated as catch-up contributions pursuant to paragraph (c) of this section because they exceed the ADP limit in paragraph (b)(1)(iii) of this section. In addition, a section 401(k) plan is not treated as failing to satisfy section 401(k)(8) merely because elective deferrals described in the preceding sentence are not distributed or recharacterized as employee contributions. Similarly, a SEP is not treated as failing to satisfy section 408(k)(6)(A)(iii) merely because catch-up contributions are not treated as excess contributions with respect to a catch-up eligible participant under the rules of section 408(k)(6)(C). Notwithstanding the fact that elective deferrals described in this paragraph (d)(2)(iii) are not distributed, such elective deferrals are still considered to be excess contributions under section 401(k)(8), and accordingly, matching contributions with respect to such elective deferrals are permitted to be forfeited under the rules of section 411(a)(3)(G).

(3) Contributions not taken into account for other nondiscrimination purposes

(i) Application for top-heavy. Catch-up contributions with respect to the current plan year are not taken into account for purposes of section 416. However, catch-up contributions for prior years are taken into account for purposes of section 416. Thus, catch-up contributions for prior years are included in the account balances that are used in determining whether the plan is top-heavy under section 416(g).

(ii) Application for section 410(b). Catch-up contributions with respect to the current plan year are not taken into account for purposes of section 410(b). Thus, catch-up contributions are not taken into account in determining the average benefit percentage under § 1.410(b)-5 for the year if benefit percentages are determined based on current year contributions. However, catch-up contributions for prior years are taken into account for purposes of section 410(b). Thus, catch-up contributions for prior years would be included in the account balances that are used in determining the average benefit percentage if allocations for prior years are taken into account.

(4) Availability of catch-up contributions. An applicable employer plan does not violate § 1.401(a)(4)-4 merely because the group of employees for whom catch-up contributions are currently available (i.e., the catch-up eligible participants) is not a group of employees that would satisfy section 410(b) (without regard to § 1.410(b)-5). In addition, a catch-up eligible participant is not treated as having a right to a different rate of allocation of matching contributions merely because an otherwise nondiscriminatory schedule of matching rates is applied to elective deferrals that include catch-up contributions. The rules in this paragraph (d)(4) also apply for purposes of satisfying the requirements of section 403(b)(12).

(e) Universal availability requirement

(1) General rule

(i) Effective opportunity. An applicable employer plan that offers catch-up contributions and that is otherwise subject to section 401(a)(4) (including a plan that is subject to section 401(a)(4) pursuant to section 403(b)(12)) will not satisfy the requirements of section 401(a)(4) unless all catch-up eligible participants who participate under any applicable employer plan maintained by the employer are provided with an effective opportunity to make the same dollar amount of catch-up contributions. A plan fails to provide an effective opportunity to make catch-up contributions if it has an applicable limit (e.g., an employer-provided limit) that applies to a catch-up eligible participant and does not permit the participant to make elective deferrals in excess of that limit. An applicable employer plan does not fail to satisfy the universal availability requirement of this paragraph (e) solely because an employer-provided limit does not apply to all employees or different limits apply to different groups of employees under paragraph (b)(2)(i) of this section. However, a plan may not provide lower employer-provided limits for catch-up eligible participants.

(ii) Certain practices permitted

(A) Proration of limit. An applicable employer plan does not fail to satisfy the universal availability requirement of this paragraph (e) merely because the plan allows participants to defer an amount equal to a specified percentage of compensation for each payroll period and for each payroll period permits each catch-up eligible participant to defer a pro-rata share of the applicable dollar catch-up limit in addition to that amount.

(B) Cash availability. An applicable employer plan does not fail to satisfy the universal availability requirement of this paragraph (e) merely because it restricts the elective deferrals of any employee (including a catch-up eligible participant) to amounts available after other withholding from the employee's pay (e.g., after deduction of all applicable income and employment taxes). For this purpose, an employer limit of 75% of compensation or higher will be treated as limiting employees to amounts available after other withholdings.

(2) Certain employees disregarded. An applicable employer plan does not fail to satisfy the universal availability requirement of this paragraph (e) merely because employees described in section 410(b)(3) (e.g., collectively bargained employees) are not provided the opportunity to make catch-up contributions.

(3) Exception for certain plans. An applicable employer plan does not fail to satisfy the universal availability requirement of this paragraph (e) merely because another applicable employer plan that is a section 457 eligible governmental plan does not provide for catch-up contributions to the extent set forth in section 414(v)(6)(C) and paragraph (a)(3) of this section.

(4) Exception for section 410(b)(6)(C)(ii) period. If an applicable employer plan satisfies the universal availability requirement of this paragraph (e) before an acquisition or disposition described in § 1.410(b)-2(f) and would fail to satisfy the universal availability requirement of this paragraph (e) merely because of such event, then the applicable employer plan shall continue to be treated as satisfying this paragraph (e) through the end of the period determined under section 410(b)(6)(C)(ii).

(f) Special rules for an employer that sponsors multiple plans

(1) General rule. For purposes of paragraph (c) of this section, all applicable employer plans, other than section 457 eligible governmental plans, maintained by the same employer are treated as one plan and all section 457 eligible governmental plans maintained by the same employer are treated as one plan. Thus, the total amount of catch-up contributions under all applicable employer plans of an employer (other than section 457 eligible governmental plans) is limited to the applicable dollar catch-up limit for the taxable year, and the total amount of catch-up contributions for all section 457 eligible governmental plans of an employer is limited to the applicable dollar catch-up limit for the taxable year.

(2) Coordination of employer-provided limits. An applicable employer plan is permitted to allow a catch-up eligible participant to defer amounts in excess of an employer-provided limit under that plan without regard to whether elective deferrals made by the participant have been treated as catch-up contributions for the taxable year under another applicable employer plan aggregated with such plan under this paragraph (f). However, to the extent elective deferrals under another plan maintained by the employer have already been treated as catch-up contributions during the taxable year, the elective deferrals under the plan may be treated as catch-up contributions only up to the amount remaining under the catch-up limit for the year. Any other elective deferrals that exceed the employer-provided limit may not be treated as catch-up contributions and must satisfy the otherwise applicable nondiscrimination rules. For example, the right to make contributions in excess of the employer-provided limit is another right or feature which must satisfy § 1.401(a)(4)-4 to the extent that the contributions are not catch-up contributions. Also, contributions in excess of the employer provided limit are taken into account under the ADP test to the extent they are not catch-up contributions.

(3) Allocation rules. If a catch-up eligible participant makes additional elective deferrals in excess of an applicable limit under paragraph (b)(1) of this section under more than one applicable employer plan that is aggregated under the rules of this paragraph (f), the applicable employer plan under which elective deferrals in excess of an applicable limit are treated as catch-up contributions is permitted to be determined in any manner that is not inconsistent with the manner in which such amounts were actually deferred under the plan.

(g) Definitions

(1) Applicable employer plan. The term applicable employer plan means a section 401(k) plan, a SIMPLE IRA plan as defined in section 408(p), a simplified employee pension plan as defined in section 408(k) (SEP), a plan or contract that satisfies the requirements of section 403(b), or a section 457 eligible governmental plan.

(2) Elective deferral. The term elective deferral means an elective deferral within the meaning of section 402(g)(3) or any contribution to a section 457 eligible governmental plan.

(3) Catch-up eligible participant. An employee is a catch-up eligible participant for a taxable year if—

(i) The employee is eligible to make elective deferrals under an applicable employer plan (without regard to section 414(v) or this section); and

(ii) The employee's 50th or higher birthday would occur before the end of the employee's taxable year.

(4) Other definitions.

(i) The terms employer, employee, section 401(k) plan, and highly compensated employee have the meanings provided in § 1.410(b)-9.

(ii) The term section 457 eligible governmental plan means an eligible deferred compensation plan described in section 457(b) that is established and maintained by an eligible employer described in section 457(e)(1)(A).

(h) Examples. The following examples illustrate the application of this section. For purposes of these examples, the limit under section 401(a)(30) is $15,000 and the applicable dollar catch-up limit is $5,000 and, except as specifically provided, the plan year is the calendar year. In addition, it is assumed that the participant's elective deferrals under all plans of the employer do not exceed the participant's section 415(c)(3) compensation, that the taxable year of the participant is the calendar year and that any correction pursuant to section 401(k)(8) is made through distribution of excess contributions. The examples are as follows:

Example 1.
(i) Participant A is eligible to make elective deferrals under a section 401(k) plan, Plan P. Plan P does not limit elective deferrals except as necessary to comply with sections 401(a)(30) and 415. In 2006, Participant A is 55 years old. Plan P also provides that a catch-up eligible participant is permitted to defer amounts in excess of the section 401(a)(30) limit up to the applicable dollar catch-up limit for the year. Participant A defers $18,000 during 2006.
(ii) Participant A's elective deferrals in excess of the section 401(a)(30) limit ($3,000) do not exceed the applicable dollar catch-up limit for 2006 ($5,000). Under paragraph (a)(1) of this section, the $3,000 is a catch-up contribution and, pursuant to paragraph (d)(2)(i) of this section, it is not taken into account in determining Participant A's ADR for purposes of section 401(k)(3).

Example 2.
(i) Participants B and C, who are highly compensated employees each earning $120,000, are eligible to make elective deferrals under a section 401(k) plan, Plan Q. Plan Q limits elective deferrals as necessary to comply with section 401(a)(30) and 415, and also provides that no highly compensated employee may make an elective deferral at a rate that exceeds 10% of compensation. However, Plan Q also provides that a catch-up eligible participant is permitted to defer amounts in excess of 10% during the plan year up to the applicable dollar catch-up limit for the year. In 2006, Participants B and C are both 55 years old and, pursuant to the catch-up provision in Plan Q, both elect to defer 10% of compensation plus a pro-rata portion of the $5,000 applicable dollar catch-up limit for 2006. Participant B continues this election in effect for the entire year, for a total elective contribution for the year of $17,000. However, in July 2006, after deferring $8,500, Participant C discontinues making elective deferrals.
(ii) Once Participant B's elective deferrals for the year exceed the section 401(a)(30) limit ($15,000), subsequent elective deferrals are treated as catch-up contributions as they are deferred, provided that such elective deferrals do not exceed the catch-up contribution limit for the taxable year. Since the $2,000 in elective deferrals made after Participant B reaches the section 402(g) limit for the calendar year does not exceed the applicable dollar catch-up limit for 2006, the entire $2,000 is treated as a catch-up contribution.
(iii) As of the last day of the plan year, Participant B has exceeded the employer-provided limit of 10% (10% of $120,000 or $12,000 for Participant B) by an additional $3,000. Since the additional $3,000 in elective deferrals does not exceed the $5,000 applicable dollar catch-up limit for 2006, reduced by the $2,000 in elective deferrals previously treated as catch-up contributions, the entire $3,000 of elective deferrals is treated as a catch-up contribution.
(iv) In determining Participant B's ADR, the $5,000 of catch-up contributions are subtracted from Participant B's elective deferrals for the plan year under paragraph (d)(2)(i) of this section. Accordingly, Participant B's ADR is 10% ($12,000/$120,000). In addition, for purposes of applying the rules of section 401(k)(8), Participant B is treated as having elective deferrals of $12,000.
(v) Participant C's elective deferrals for the year do not exceed an applicable limit for the plan year. Accordingly, Participant C's $8,500 of elective deferrals must be taken into account in determining Participant C's ADR for purposes of section 401(k)(3).

Example 3.
(i) The facts are the same as in Example 2, except that Plan Q is amended to change the maximum permitted deferral percentage for highly compensated employees to 7%, effective for deferrals after April 1, 2006. Participant B, who has earned $40,000 in the first 3 months of the year and has been deferring at a rate of 10% of compensation plus a pro-rata portion of the $5,000 applicable dollar catch-up limit for 2006, reduces the 10% of pay deferral rate to 7% for the remaining 9 months of the year (while continuing to defer a pro-rata portion of the $5,000 applicable dollar catch-up limit for 2006). During those 9 months, Participant B earns $80,000. Thus, Participant B's total elective deferrals for the year are $14,600 ($4,000 for the first 3 months of the year plus $5,600 for the last 9 months of the year plus an additional $5,000 throughout the year).
(ii) The employer-provided limit for Participant B for the plan year is $9,600 ($4,000 for the first 3 months of the year, plus $5,600 for the last 9 months of the year). Accordingly, Participant B's elective deferrals for the year that are in excess of the employer-provided limit are $5,000 (the excess of $14,600 over $9,600), which does not exceed the applicable dollar catch-up limit of $5,000.
(iii) Alternatively, Plan Q may provide that the employer-provided limit is determined as the time-weighted average of the different deferral percentage limits over the course of the year. In this case, the time-weighted average limit is 7.75% for all participants, and the applicable limit for Participant B is 7.75% of $120,000, or $9,300. Accordingly, Participant B's elective deferrals for the year that are in excess of the employer-provided limit are $5,300 (the excess of $14,600 over $9,300). Since the amount of Participant B's elective deferrals in excess of the employer-provided limit ($5,300) exceeds the applicable dollar catch-up limit for the taxable year, only $5,000 of Participant B's elective deferrals may be treated as catch-up contributions. In determining Participant B's actual deferral ratio, the $5,000 of catch-up contributions are subtracted from Participant B's elective deferrals for the plan year under paragraph (d)(2)(i) of this section. Accordingly, Participant B's actual deferral ratio is 8% ($9,600/$120,000). In addition, for purposes of applying the rules of section 401(k)(8), Participant B is treated as having elective deferrals of $9,600.

Example 4.
(i) The facts are the same as in Example 1. In addition to Participant A, Participant D is a highly compensated employee who is eligible to make elective deferrals under Plan P. During 2006, Participant D, who is 60 years old, elects to defer $14,000.
(ii) The ADP test is run for Plan P (after excluding the $3,000 in catch-up contributions from Participant A's elective deferrals), but Plan P needs to take corrective action in order to pass the ADP test. After applying the rules of section 401(k)(8)(C) to allocate the total excess contributions determined under section 401(k)(8)(B), the maximum deferrals which may be retained by any highly compensated employee in Plan P is $12,500.
(iii) Pursuant to paragraph (b)(1)(iii) of this section, the ADP limit under Plan P of $12,500 is an applicable limit. Accordingly, $1,500 of Participant D's elective deferrals exceed the applicable limit. Similarly, $2,500 of Participant A's elective deferrals (other than the $3,000 of elective deferrals treated as catch-up contributions because they exceed the section 401(a)(30) limit) exceed the applicable limit.
(iv) The $1,500 of Participant D's elective deferrals that exceed the applicable limit are less than the applicable dollar catch-up limit and are treated as catch-up contributions. Pursuant to paragraph (d)(2)(iii) of this section, Plan P must retain Participant D's $1,500 in elective deferrals and Plan P is not treated as failing to satisfy section 401(k)(8) merely because the elective deferrals are not distributed to Participant D.
(v) The $2,500 of Participant A's elective deferrals that exceed the applicable limit are greater than the portion of the applicable dollar catch-up limit ($2,000) that remains after treating the $3,000 of elective deferrals in excess of the section 401(a)(30) limit as catch-up contributions. Accordingly, $2,000 of Participant A's elective deferrals are treated as catch-up contributions. Pursuant to paragraph (d)(2)(iii) of this section, Plan P must retain Participant A's $2,000 in elective deferrals and Plan P is not treated as failing to satisfy section 401(k)(8) merely because the elective deferrals are not distributed to Participant A. However, $500 of Participant A's elective deferrals cannot be treated as catch-up contributions and must be distributed to Participant A in order to satisfy section 401(k)(8).

Example 5.
(i) Participant E is a highly compensated employee who is a catch-up eligible participant under a section 401(k) plan, Plan R, with a plan year ending October 31, 2006. Plan R does not limit elective deferrals except as necessary to comply with section 401(a)(30) and section 415. Plan R permits all catch-up eligible participants to defer an additional amount equal to the applicable dollar catch-up limit for the year ($5,000) in excess of the section 401(a)(30) limit. Participant E did not exceed the section 401(a)(30) limit in 2005 and did not exceed the ADP limit for the plan year ending October 31, 2005. Participant E made $3,200 of deferrals in the period November 1, 2005 through December 31, 2005 and an additional $16,000 of deferrals in the first 10 months of 2006, for a total of $19,200 in elective deferrals for the plan year.
(ii) Once Participant E's elective deferrals for the calendar year 2006 exceed $15,000, subsequent elective deferrals are treated as catch-up contributions at the time they are deferred, provided that such elective deferrals do not exceed the applicable dollar catch-up limit for the taxable year. Since the $1,000 in elective deferrals made after Participant E reaches the section 402(g) limit for the calendar year does not exceed the applicable dollar catch-up limit for 2006, the entire $1,000 is a catch-up contribution. Pursuant to paragraph (d)(2)(i) of this section, $1,000 is subtracted from Participant E's $19,200 in elective deferrals for the plan year ending October 31, 2006 in determining Participant E's ADR for that plan year.
(iii) The ADP test is run for Plan R (after excluding the $1,000 in elective deferrals in excess of the section 401(a)(30) limit), but Plan R needs to take corrective action in order to pass the ADP test. After applying the rules of section 401(k)(8)(C) to allocate the total excess contributions determined under section 401(k)(8)(C), the maximum deferrals that may be retained by any highly compensated employee under Plan R for the plan year ending October 31, 2006 (the ADP limit) is $14,800.
(iv) Under paragraph (d)(2)(ii) of this section, elective deferrals that exceed the section 401(a)(30) limit under Plan R are also subtracted from Participant E's elective deferrals under Plan R for purposes of applying the rules of section 401(k)(8). Accordingly, for purposes of correcting the failed ADP test, Participant E is treated as having contributed $18,200 of elective deferrals in Plan R. The amount of elective deferrals that would have to be distributed to Participant E in order to satisfy section 401(k)(8)(C) is $3,400 ($18,200 minus $14,800), which is less than the excess of the applicable dollar catch-up limit ($5,000) over the elective deferrals previously treated as catch-up contributions under Plan R for the taxable year ($1,000). Under paragraph (d)(2)(iii) of this section, Plan R must retain Participant E's $3,400 in elective deferrals and is not treated as failing to satisfy section 401(k)(8) merely because the elective deferrals are not distributed to Participant E.
(v) Even though Participant E's elective deferrals for the calendar year 2006 have exceeded the section 401(a)(30) limit, Participant E can continue to make elective deferrals during the last 2 months of the calendar year, since Participant E's catch-up contributions for the taxable year are not taken into account in applying the section 401(a)(30) limit for 2006. Thus, Participant E can make an additional contribution of $3,400 ($15,000 minus ($16,000 minus $4,400)) without exceeding the section 401(a)(30) for the calendar year and without regard to any additional catch-up contributions. In addition, Participant E may make additional catch-up contributions of $600 (the $5,000 applicable dollar catch-up limit for 2006, reduced by the $4,400 ($1,000 plus $3,400) of elective deferrals previously treated as catch-up contributions during the taxable year). The $600 of catch-up contributions will not be taken into account in the ADP test for the plan year ending October 31, 2007.

Example 6.
(i) The facts are the same as in Example 5, except that Participant E exceeded the section 401(a)(30) limit for 2005 by $1,300 prior to October 31, 2005, and made $600 of elective deferrals in the period November 1, 2005, through December 31, 2005 (which were catch-up contributions for 2005). Thus, Participant E made $16,600 of elective deferrals for the plan year ending October 31, 2006.
(ii) Once Participant E's elective deferrals for the calendar year 2006 exceed $15,000, subsequent elective deferrals are treated as catch-up contributions as they are deferred, provided that such elective deferrals do not exceed the applicable dollar catch-up limit for the taxable year. Since the $1,000 in elective deferrals made after Participant E reaches the section 402(g) limit for calendar year 2006 does not exceed the applicable dollar catch-up limit for 2006, the entire $1,000 is a catch-up contribution. Pursuant to paragraph (d)(2)(i) of this section, $1,000 is subtracted from Participant E's elective deferrals in determining Participant E's ADR for the plan year ending October 31, 2006. In addition, the $600 of catch-up contributions from the period November 1, 2005 to December 31, 2005 are subtracted from Participant E's elective deferrals in determining Participant E's ADR. Thus, the total elective deferrals taken into account in determining Participant E's ADR for the plan year ending October 31, 2006, is $15,000 ($16,600 in elective deferrals for the current plan year, less $1,600 in catch-up contributions).
(iii) The ADP test is run for Plan R (after excluding the $1,600 in elective deferrals in excess of the section 401(a)(30) limit), but Plan R needs to take corrective action in order to pass the ADP test. After applying the rules of section 401(k)(8)(C) to allocate the total excess contributions determined under section 401(k)(8)(C), the maximum deferrals that may be retained by any highly compensated employee under Plan R (the ADP limit) is $14,800.
(iv) Under paragraph (d)(2)(ii) of this section, elective deferrals that exceed the section 401(a)(30) limit under Plan R are also subtracted from Participant E's elective deferrals under Plan R for purposes of applying the rules of section 401(k)(8). Accordingly, for purposes of correcting the failed ADP test, Participant E is treated as having contributed $15,000 of elective deferrals in Plan R. The amount of elective deferrals that would have to be distributed to Participant E in order to satisfy section 401(k)(8)(C) is $200 ($15,000 minus $14,800), which is less than the excess of the applicable dollar catch-up limit ($5,000) over the elective deferrals previously treated as catch-up contributions under Plan R for the taxable year ($1,000). Under paragraph (d)(2)(iii) of this section, Plan R must retain Participant E's $200 in elective deferrals and is not treated as failing to satisfy section 401(k)(8) merely because the elective deferrals are not distributed to Participant E.
(v) Even though Participant E's elective deferrals for calendar year 2006 have exceeded the section 401(a)(30) limit, Participant E can continue to make elective deferrals during the last 2 months of the calendar year, since Participant E's catch-up contributions for the taxable year are not taken into account in applying the section 401(a)(30) limit for 2006. Thus Participant E can make an additional contribution of $200 ($15,000 minus ($16,000 minus $1,200)) without exceeding the section 401(a)(30) for the calendar year and without regard to any additional catch-up contributions. In addition, Participant E may make additional catch-up contributions of $3,800 (the $5,000 applicable dollar catch-up limit for 2006, reduced by the $1,200 ($1,000 plus $200) of elective deferrals previously treated as catch-up contributions during the taxable year). The $3,800 of catch-up contributions will not be taken into account in the ADP test for the plan year ending October 31, 2007.

Example 7.
(i) Participant F, who is 58 years old, is a highly compensated employee who earns $100,000 per year. Participant F participates in a section 401(k) plan, Plan S, for the first 6 months of the year and then transfers to another section 401(k) plan, Plan T, sponsored by the same employer, for the second 6 months of the year. Plan S limits highly compensated employees' elective deferrals to 6% of compensation for the period of participation, but permits catch-up eligible participants to defer amounts in excess of 6% during the plan year, up to the applicable dollar catch-up limit for the year. Plan T limits highly compensated employees' elective deferrals to 8% of compensation for the period of participation, but permits catch-up eligible participants to defer amounts in excess of 8% during the plan year, up to the applicable dollar catch-up limit for the year. Participant F earned $50,000 in the first 6 months of the year and deferred $6,000 under Plan S. Participant F also deferred $6,500 under Plan T.
(ii) As of the last day of the plan year, Participant F has $3,000 in elective deferrals under Plan S that exceed the employer-provided limit of $3,000. Under Plan T, Participant F has $2,500 in elective deferrals that exceed the employer-provided limit of $4,000. The total amount of elective deferrals in excess of employer-provided limits, $5,500, exceeds the applicable dollar catch-up limit by $500. Accordingly, $500 of the elective deferrals in excess of the employer-provided limits are not catch-up contributions and are treated as regular elective deferrals (and are taken into account in the ADP test). The determination of which elective deferrals in excess of an applicable limit are treated as catch-up contributions is permitted to be made in any manner that is not inconsistent with the manner in which such amounts were actually deferred under Plan S and Plan T.

Example 8.
(i) Employer X sponsors Plan P, which provides for matching contributions equal to 50% of elective deferrals that do not exceed 10% of compensation. Elective deferrals for highly compensated employees are limited, on a payroll-by-payroll basis, to 10% of compensation. Employer X pays employees on a monthly basis. Plan P also provides that elective contributions are limited in accordance with section 401(a)(30) and other applicable statutory limits. Plan P also provides for catch-up contributions. Under Plan P, for purposes of calculating the amount to be treated as catch-up contributions (and to be excluded from the ADP test), amounts in excess of the 10% limit for highly compensated employees are determined at the end of the plan year based on compensation used for purposes of ADP testing (testing compensation), a definition of compensation that is different from the definition used under the plan for purposes of calculating elective deferrals and matching contributions during the plan year (deferral compensation).
(ii) Participant A, a highly compensated employee, is a catch-up eligible participant under Plan P with deferral compensation of $10,000 per monthly payroll period. Participant A defers 10% per payroll period for the first 10 months of the year, and is allocated a matching contribution each payroll period of $500. In addition, Participant A defers an additional $4,000 during the first 10 months of the year. Participant A then reduces deferrals during the last 2 months of the year to 5% of compensation. Participant A is allocated a matching contribution of $250 for each of the last 2 months of the plan year. For the plan year, Participant A has $15,000 in elective deferrals and $5,500 in matching contributions.
(iii) A's testing compensation is $118,000. At the end of the plan year, based on 10% of testing compensation, or $11,800, Plan P determines that A has $3,200 in deferrals that exceed the 10% employer provided limit. Plan P excludes $3,200 from ADP testing and calculates A's ADR as $11,800 divided by $118,000, or 10%. Although A has not been allocated a matching contribution equal to 50% of $11,800, because Plan P provides that matching contributions are calculated based on elective deferrals during a payroll period as a percentage of deferral compensation, Plan P is not required to allocate an additional $400 of matching contributions to A.
