How Crypto Casino Winnings Are Taxed in South Carolina
When you participate in online crypto casinos, sportsbooks, or social sweepstakes from South Carolina, your tax obligations involve two independent layers of government authority: the federal Internal Revenue Service (IRS) and the South Carolina Department of Revenue (SCDOR).
Gambling winnings are fully taxable on South Carolina Form SC1040.
Federal Tax Still Applies
Regardless of South Carolina’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.

- 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.
