How long does a D.C. taxpayer have to file a refund claim for an overpayment?

Plain-English summary

D.C. taxpayers must file a claim for refund of an overpayment within the later of two three-year periods:

1. Three years from the return's due date; or
2. Three years from the date the tax was paid.

OTR's example involved a taxpayer who obtained an extension, paid an estimate on the original April due date, filed the return and paid the balance in October, and later filed an amended return claiming an overpayment. Because the extended October return due date was later than the April payment date, OTR measured the deadline from the extended due date and treated the refund claim as timely.

The source's placeholder-date example contains an internal inconsistency: it prints the expiration date as October 15 of year 0002 while also describing a three-year period and a claim filed in year 0005. This page does not silently correct the official text; the controlling rule above and OTR's conclusion that the example claim was timely are stated verbatim in substance.

What this means for you

Taxpayers filing amended returns

Check both dates before filing a refund claim: the return's due date and the date the tax was paid. The later date starts the controlling three-year period under this ruling.

Tax professionals

A timely extension may make the extended return due date later than the payment date. Preserve extension and payment records so the filing deadline can be demonstrated.

Common questions

Is the deadline always three years from payment? No. The deadline is the later of three years from the return due date or three years from payment.

Can an extension affect the refund deadline? Yes. In OTR's example, the timely extended return due date was later than the payment date and controlled the calculation.

What filing did the taxpayer use to claim the refund? The taxpayer filed an amended return claiming an overpayment.

Refunds-Statute of Limitations D.C. Official Code § 47-4304
Statute of Limitations-Refunds D.C. Official Code § 47-4304
Question: When is a taxpayer permitted to file a claim for refund?
The controlling statute to determine the deadline for filing a claim for refund for an
overpayment is D.C. Official Code § 47-4304. D.C. Official Code § 47-4304(a)
provides that a claim for refund for an overpayment shall not be allowed unless the
taxpayer files a claim for a refund within the later of:

1. Three years from the due date of the return, or
2. Three years from the date the tax was paid.
   Example:
   On 04/15/0002, the taxpayer timely files an extension of time to file the tax return for tax
   year 0001 and pays a reasonable estimate of the tax liability for tax year 0001.
   On 10/15/0002, the taxpayer timely files a District tax return and pays the balance of the
   0001 tax liability.
   On 10/10/0005, the taxpayer files an amended return claiming an overpayment of the tax
   year 0001 D.C. taxes.
   Since the tax is considered paid on 4/15/0002 and the due date of the return was timely
   extended to 10/15/0002, which is later than the date of payment, the deadline (i.e.,
   expiration of the statute of limitations) to file a claim for refund is 10/15/0002.
   Since the claim for refund was filed October 10, 0005, which is before the expiration of
   the statute of limitations (three years from the extended due date of the return, or October
   15, 0002), the claim for refund was timely filed.
