Return Filing Period. Returns of tax withheld from wages are required to be filed with the Office of Tax and Revenue on a quarterly or annual basis. Entities reporting non- wage tax withheld shall file a return on an annual basis.
The DCFO shall assign an account registration number to each employer or entity required to file returns and assign them either a quarterly or annual return filing period. Returns shall be filed in accordance with the assigned filing period, and shall continue to be filed on that basis until the DCFO determines that the employer's return shall be made for a different filing period.
Return Filing Deadlines. Quarterly withholding returns shall be filed on or before the last day of the month following the close of each quarterly reporting period. Annual withholding returns shall be filed on or before the last day of January of each year for the preceding year.
All returns shall be made on forms prescribed by the DCFO.
Withholding tax returns are only available electronically by download at mytax.dc.gov. Failure to obtain forms or returns does not relieve a taxpayer of the responsibility to file and pay timely.
Withholding tax returns can be filed electronically, for either single or bulk filers, at mytax.dc.gov. Electronic filing is the method preferred by the Office of Tax and Revenue.
Final Returns. The last return for any employer required to deduct and withhold tax under the Act who, during a calendar year, ceases to engage in business or ceases to pay wages, shall be marked by that employer as the "FINAL RETURN." The final return shall state the period for which it is made and the date of the last payment of wages.
If a taxpayer amends a tax return, an amended return shall be filed within three years of the original due date of the return and must be marked amended on the return in order to be processed.
If the payment of the tax results in an overpayment of the tax required to be withheld and paid, a credit will be applied to the next reporting period. Alternatively, to receive a refund of such overpayment of tax, the taxpayer shall request a refund by indicating on the tax return.
