D.C. Mun. Regs. tit. 9, r. 9-150
If it is determined by the Deputy Chief Financial Officer that there has been an overpayment of any tax (whether as deficiency or otherwise), interest shall be allowed and paid upon that overpayment of tax at the rate of six per cent (6%) per annum from the date the overpayment was paid until the date of refund, except as otherwise provided in this section or the Act.
That part of any overpayment which was not assessed and paid as a deficiency or as additional tax shall bear interest only from the date on which a claim for refund was filed:
Interest on overpayments resulting from excessive withholding, excessive payments on declarations, or both, shall in no event begin to accrue prior to ninety (90) days after the overpayment is made or after the date of the filing of a final return, whichever is later.
For the purposes of this section, any tax deducted and withheld during any calendar year and any amounts paid except as provided for in § 149.2 prior to the fifteenth (15th) day of the fourth (4th) month after the close of the taxable year as estimated tax shall be deemed to have been paid on the fifteenth (15th) day of the fourth (4th) month following the close of the taxable year.
No interest may be paid unless a properly completed claim for refund is filed with the Deputy Chief Financial Officer.
If the final return filed by an individual for the taxable year shows an overpayment resulting from excessive withholding or excessive payments on declarations, or both, an automatic refund of the overpayment shall be made; Provided, that all of the withholding statements supporting all of the withholding taxes claimed as a credit is submitted with the final income tax return. No interest on overpayments shall be allowed or paid on refunds made in this manner.
If a final return shows an overpayment of less than two dollars ($ 2), it shall be refunded only upon application to the Deputy Chief Financial Officer.
No refund of estimated tax previously paid shall be made except upon the filing of a final income tax return on Form D-40 after the close of the taxable year.
Each claim for refund shall be in writing, under oath, and shall state the specific grounds upon which the claim is based.
Forms to be used in filing a claim for refund may be obtained from the Deputy Chief Financial Officer, upon request.
Notwithstanding any other provisions of this section, a refund due on the return of an individual may be intercepted by the Deputy Chief Financial Officer, Office of Tax and Revenue in accordance with the provisions of § 11(a) of Title XII of the Act (D.C. Code § 47-1812(a)(4)(4a)) as amended.

For the purposes of this section, the phrase "authorized official" shall mean, as it applies to the affected agency, the Deputy Director of the Department of Human Services or the Vice President of the Financial Management Division of the University of District of Columbia.
The interception of a refund requested by married persons filing on a combined separate form (Columns A and B of Form D-40) shall be limited to the net refund attributable to the spouse who has a set-off. The following example illustrate the application of § 150.15:
Example A:
Husband | (Col A) | Refund | $ 200.00 |

Total Refund | $ 300.00 |
The husband has a set-off. He is in arrears of child-support payments. Only two hundred dollars ($ 200.00) is subject to interception.
Example B:
Husband | (Col. A) | Refund | $ 200.00 |
Wife | (Col. B) | Balance | $ 250.00 |
Net Balance Due | $ 50.00 |

Example C:
Husband | (Col. A) | Balance Due | $ 100.00 |
Wife | (Col. B) | Refund | $ 150.00 |
Net Balance Due | $ 50.00 |
