Subpart C of this part prescribes procedures for debt collection by tax refund offset, as authorized by section 3720A of subchapter II, chapter 37 of title 31 of the United States Code (31 U.S.C. 3720A) and in accordance with applicable IRS regulations (26 CFR 301-6402.6), including a related procedure for disclosure to a consumer reporting agency. These procedures apply to determinations that a debt of at least $25 is past-due and legally enforceable, to referrals by the PBGC of past-due, legally enforceable debts to the IRS for offset, and to any subsequent corrections of information contained in such referrals.
