20 CFR § 404.1271 - Adjustment of overpayment of contributions - for wages paid prior to 1987.
(a) General. If a State pays more than the correct amount of contributions, the State shall adjust the overpayment with the next contribution return filed on which the amount owed equals or exceeds the amount of the overpayment.
(b) Overpayment due to overreporting of wages -
(1) Report to file. If the overpayment is due to the State's reporting more than the correct amount of wages paid to one or more employees during a reporting period and the overpayment is not adjusted under paragraph (a) of this section, the State shall file a report on the appropriate form showing:
(i) The corrected wage data as prescribed by SSA; and
(ii) The reason why the original reporting was incorrect.
(2) Refund or credit of overpayment where section 218(e)(2) of the Act not applicable. If:
(ii) The State paid to the Secretary of the Treasury those contributions plus a matching amount in excess of the taxes which would have been required from an employer under section 3111 of the Code; and
(iii) The services of the employees in question would have constituted employment under section 3121(b) of the Code; and
(iv) Section 218(e)(2) of the Act as it read prior to the enactment of Pub. L. 99-509 does not apply (see § 404.1256(a)), then the State shall adjust the overpaid contributions under paragraph (b)(1) of this section. With its adjustment the State, where appropriate, shall include on the prescribed form a statement that the employees from whom the excess contributions were collected have not received nor expect to receive a refund of excess contributions under section 6413(c) of the Internal Revenue Code of 1954 (see § 404.1275(b)). Generally, if the State does not include this statement with its adjustment request, we only refund or credit the State for up to one-half of the overpaid amount.
(c) Refund or credit of overpayment where section 218(e)(2) of the Act applicable -
(1) General. If -
(i) The overreporting of the amount of wages paid to one or more employees during a reporting period(s) is due to a computation of contributions under § 404.1256 for a year or years prior to the year in which the agreement or modification providing for the computation is entered into, or
(ii) The overreporting is due to a failure to compute § 404.1256,
(2) Amount of refund or credit. If the State collects excess contributions from employees, the State's claim for refund or credit is limited to the overpaid amounts. (See § 404.1275 relating to adjustment of employee contributions.) If -
(i) The State collected the correct amount of contributions from employees based on the amount of wages reported and the Forms W-2 issued to the employees show only the amount of contributions actually collected, but the amount of wages reported is being adjusted downward, or
(ii) The State collects excess contributions from employees but Forms W-2 have not been issued for an amount of wages which is being adjusted downward, the State may claim a refund or credit for the overpaid amounts. Where the State's claim for refund or credit is for the total overpaid amount, the adjustment report shall include a statement that excess contributions have not been collected from employees, or, where excess contributions have been collected, that Forms W-2 have not been issued and that, when issued, they will show the correct amount of employee contributions.
