In the case of any overpayment, the Secretary, within the applicable period of limitations, may credit the amount of such overpayment, including any interest allowed thereon, against any liability in respect of an internal revenue tax on the part of the person who made the overpayment and shall, subject to subsections (c), (d), (e), and (f), refund any balance to such person.

The Secretary is authorized to prescribe regulations providing for the crediting against the estimated income tax for any taxable year of the amount determined by the taxpayer or the Secretary to be an overpayment of the income tax for a preceding taxable year.

The amount of any overpayment to be refunded to the person making the overpayment shall be reduced by the amount of any past-due support (as defined in section 464(c) of the Social Security Act) owed by that person of which the Secretary has been notified by a State in accordance with section 464 of such Act. The Secretary shall remit the amount by which the overpayment is so reduced to the State collecting such support and notify the person making the overpayment that so much of the overpayment as was necessary to satisfy his obligation for past-due support has been paid to the State. The Secretary shall apply a reduction under this subsection first to an amount certified by the State as past due support under section 464 of the Social Security Act before any other reductions allowed by law. This subsection shall be applied to an overpayment prior to its being credited to a person’s future liability for an internal revenue tax.

Upon receiving notice from any Federal agency that a named person owes a past-due legally enforceable debt (other than past-due support subject to the provisions of subsection (c)) to such agency, the Secretary shall—

(B) pay the amount by which such overpayment is reduced under subparagraph (A) to such agency; and

(C) notify the person making such overpayment that such overpayment has been reduced by an amount necessary to satisfy such debt.

If the Secretary receives notice from a Federal agency or agencies of more than one debt subject to paragraph (1) that is owed by a person to such agency or agencies, any overpayment by such person shall be applied against such debts in the order in which such debts accrued.

In the case of a debt consisting of an OASDI overpayment, if the Secretary determines upon receipt of the notice referred to in paragraph (1) that the refund from which the reduction described in paragraph (1)(A) would be made is based upon a joint return, the Secretary shall—

(ii) Adjustments based on protections given to other taxpayers on joint return If the other person filing a joint return with the person owing the OASDI overpayment takes appropriate action to secure his or her proper share of the refund subject to reduction under this subsection, the Secretary shall pay such share to such other person. The Secretary shall deduct the amount of such payment from amounts which are derived from subsequent reductions in refunds under this subsection and are payable to a trust fund referred to in subparagraph (C).

(C) Deposit of amount of reduction into appropriate trust fund In lieu of payment, pursuant to paragraph (1)(B), of the amount of any reduction under this subsection to the Commissioner of Social Security, the Secretary shall deposit such amount in the Federal Old-Age and Survivors Insurance Trust Fund or the Federal Disability Insurance Trust Fund, whichever is certified to the Secretary as appropriate by the Commissioner of Social Security.
