How Crypto Casino Winnings Are Taxed in District of Columbia
When you participate in online crypto casinos, sportsbooks, or social sweepstakes from District of Columbia, your tax obligations involve two independent layers of government authority: the federal Internal Revenue Service (IRS) and the District of Columbia Office of Tax and Revenue (OTR).
Gambling winnings are fully subject to DC individual income tax and reported on Form D-40.
Federal Tax Still Applies
Regardless of District of Columbia’s state-level tax rate, federal income tax applies to 100% of your gambling winnings. The IRS classifies gambling proceeds as ordinary taxable income (IRC § 61), reported on Form 1040, Schedule 1.
- Federal Brackets: Marginal tax rates range from 10% to 37%.
- 2026 Federal Loss Limitation: For tax years beginning in 2026, IRC § 165(d) generally limits the wagering-loss deduction to 90% of wagering losses for itemizers, and the deduction cannot exceed wagering gains.
- No Form Exemption: Offshore crypto casinos rarely issue Form W-2G or Form 1099, but federal reporting is legally mandatory for all taxpayers upon constructive receipt of winnings.
- Withholding: If playing at a licensed domestic facility, 24% federal backup withholding may apply on eligible payouts.

What Happens If You Receive Winnings in Bitcoin or Crypto?

This establishes the Two-Stage Tax Rule for District of Columbia residents:
- Stage 1 (Gambling Income): You owe ordinary income tax on the U.S. dollar fair market value of the cryptocurrency at the exact moment of taxable receipt (actual or constructive receipt and dominion/control).
- Stage 2 (Capital Gains/Losses): When you later sell, swap, or spend that cryptocurrency, you incur a capital gain or loss equal to the difference between your disposal proceeds and your original adjusted cost basis established upon receipt.
