How to Complete and File DC Form FR-120: Deadline, Payment, and Penalties

DC Form FR-120 is the extension request that gives your corporation an extra six months to file the D-20 Corporation Franchise Tax Return, or seven months if you file on a combined reporting basis. File it by the original D-20 due date and include full payment of your estimated franchise tax liability. The extension covers filing only, not payment, and the Office of Tax and Revenue (OTR) will deny the request if the payment submitted with the form falls short.¹

When FR-120 Is Due

The form must reach OTR by the D-20’s original due date. Calendar-year filers have until April 15. Fiscal-year filers have the 15th day of the fourth month after their tax year closes.² Miss that date and the extension is invalid; the D-20 is treated as late from the original deadline forward.

Filling Out the Form

FR-120 is a single page. The top section asks for your Taxpayer Identification Number, business name (or designated agent), full mailing address with ZIP+4, and the tax period ending date in MMDDYYYY format.

Three checkboxes sit below the address block. Check Combined Report if your business files combined, which stretches the extension from six months to seven. Check Living or Traveling Outside the U.S. only if the responsible party is outside the continental United States and needs additional time beyond the standard extension. Check 52-53 Week Filer if your fiscal year runs on a 52-53 week cycle.¹

The Payment Worksheet

The bottom of the form is a five-line worksheet. Line 1 is your total estimated franchise tax for the period. DC’s franchise tax rate is 8.25 percent of taxable income, with a minimum tax of $250 if DC gross receipts are $1 million or less and $1,000 if they exceed $1 million.³ Line 2 is estimated franchise tax payments already made during the year, including any overpayment credit carried forward. Line 3 captures any other payments applied to the period. Add Lines 2 and 3 on Line 4. Subtract Line 4 from Line 1 on Line 5 — that is your balance due.

If Line 5 is zero or negative, you owe nothing with the form but should still file it to lock in the extended deadline. If Line 5 is positive, send the full amount with the form. Underpayment is the single most common reason OTR denies an extension.¹

How to Submit It

You can mail the form or file electronically. Businesses whose tax payment exceeds $5,000 in any period must pay electronically through MyTax.DC.gov; paper checks are not accepted at that threshold.⁴

If you mail it, send the form with a check or money order payable to the DC Treasurer to:

Office of Tax and Revenue
PO Box 96019
Washington, DC 20090-6019

Write your TIN, the tax year, and “FR-120” on the payment.⁵ If you file electronically and the funds originate from an account outside the United States, you must pay by money order in U.S. dollars or by credit card; direct bank transfers from foreign accounts are not accepted.¹

What You Get After Filing

A properly completed FR-120 with full payment is automatically approved. You do not need to wait for a confirmation letter to treat the deadline as extended. Calendar-year filers with the standard six-month extension have until October 15 to file the D-20. Combined reporting filers have until November 15. When you file the D-20, attach a copy of the FR-120.²

No additional extension beyond six or seven months is available unless the responsible party is outside the continental United States. In that case you can request up to six more months, but the total extension can never exceed one year from the original due date.¹

Penalties if You Underpay or File Late

Because the extension covers only paperwork, underpaying or skipping payment triggers a failure-to-pay penalty of 5 percent of the unpaid tax for the first month, with another 5 percent for each additional month or partial month the balance remains, up to a 25 percent ceiling. Interest also accrues on the unpaid balance.⁶

A separate failure-to-file penalty applies if you miss the extended D-20 deadline, also at 5 percent per month and capped at 25 percent. When both penalties apply in the same month, the failure-to-file amount is reduced by the failure-to-pay amount for that month, so the same period is not penalized twice.⁶

OTR charges a $65 returned-payment fee if a check or electronic payment bounces. If the bounced payment was the one submitted with the FR-120, the extension itself can be denied on top of the fee.¹
