Gambling losses
Can you deduct gambling losses in South Carolina?
South Carolina starts from federal taxable income, so gambling losses reduce your South Carolina income only if you itemized on your federal return (Schedule A). The 2025 instructions have no separate gambling-loss rule.
- South Carolina follows your federal choice, because it starts from federal taxable income, which already reflects the standard or itemized deduction.
- Under S.C. Code 12-8-530, anyone paying prizes or winnings of $500 or more must withhold a percentage equal to the maximum individual tax rate (5% for corporations). Prizes for spectator sporting events with paid admission are excluded.
- South Carolina's posted conformity date to the Internal Revenue Code is December 31, 2024, and it is not confirmed whether it adopts the 2026 federal 90% limit.

Federal courts
What the federal courts and the CFTC have said
States say prediction market sports contracts are bets that their gambling laws cover, while Kalshi and the CFTC say they are swaps, a kind of derivative that only the federal Commodity Exchange Act and the CFTC regulate. The Third Circuit appeals court sided with Kalshi against New Jersey in April 2026, while the Ninth Circuit (Nevada, August 2026) and the Sixth Circuit (Ohio and Tennessee, September 2026) ruled for the states, all at the preliminary stage. The Fourth Circuit (Maryland) heard argument in May 2026 and had not ruled as of November 3. New Jersey's petition to the Supreme Court, Flaherty v. KalshiEX (No. 26-299), is waiting on Kalshi's response due December 7, 2026, and the Court has not yet said whether it will hear the case. On October 9, 2026 the CFTC proposed a rule defining event contracts as swaps.
Apr 6, 2026
Court · U.S. Court of Appeals for the Third Circuit · KalshiEX LLC v. Flaherty (No. 25-1922)
By a 2-1 vote, the appeals court for New Jersey, Pennsylvania and Delaware upheld an order that stops New Jersey from enforcing its gambling laws against Kalshi's sports contracts for now. It found Kalshi likely to win its argument that federal law overrides the state. This is a preliminary ruling, not a final judgment.
Third Circuit opinion, Apr. 6, 2026Aug 28, 2026
Court · U.S. Court of Appeals for the Ninth Circuit · KalshiEX LLC v. Assad (No. 25-7516)
A unanimous three-judge panel upheld the order that lifted Kalshi's protection against Nevada, so Nevada may enforce its gambling laws against Kalshi's sports contracts. The court held that sports contracts are not swaps under federal law. It sent Kalshi's election contracts back to the district court. This is a preliminary ruling.
Ninth Circuit opinion, Aug. 28, 2026Sep 2, 2026
Court · Supreme Court of the United States · Flaherty v. KalshiEX, LLC (No. 26-299)
New Jersey asked the Supreme Court to review the Third Circuit ruling. Kalshi's response is due December 7, 2026 after two extensions. Many states, tribes, the NFL and others have filed friend-of-the-court briefs. The Court has not decided whether to take the case.
Supreme Court docket No. 26-299Sep 16, 2026
Court · U.S. Court of Appeals for the Ninth Circuit · Blue Lake Rancheria v. Kalshi, Inc. (No. 25-7504)
In a case brought by two California tribes, the court held the tribes are likely to win their claim that Kalshi's sports contracts offered on tribal lands break the federal Indian Gaming Regulatory Act, and sent the case back to the lower court. A Lanham Act (false advertising) claim was rejected.
Ninth Circuit opinion, Sept. 16, 2026Sep 25, 2026
Court · U.S. Court of Appeals for the Sixth Circuit · KalshiEX LLC v. Schuler (Ohio) and KalshiEX LLC v. Orgel (Tennessee) (Nos. 26-3196 and 26-5235)
A unanimous panel upheld a federal judge's refusal to block Ohio's gambling laws and threw out the order that had protected Kalshi in Tennessee. It held Kalshi's sports contracts are not swaps and, even if they were, federal law does not override the states' gambling laws. The cases go back to the lower courts.
Sixth Circuit opinion, Sept. 25, 2026Oct 9, 2026
Regulator · Commodity Futures Trading Commission
The CFTC proposed a rule that would expressly define event contracts, including those on sports, politics, culture and weather, as swaps, which would place them under federal rather than state oversight. The public may comment for 30 days after Federal Register publication (91 FR 66022). It is a proposal, not a final rule. The same day the CFTC issued an interim rule excluding casino-style gambling products, such as sportsbook wagers and casino games, from the swap definition (91 FR 65969).

Your trades
Kalshi and Polymarket profits in South Carolina
The IRS hasn’t said how prediction market trades are taxed, so you pick one of four federal methods: capital gains, ordinary income, gambling or Section 1256. South Carolina starts from your federal figures, so the method you choose federally generally carries onto your state return. If you report as gambling, the loss rules above apply. The four methods, compared.

I trade prediction markets on Kalshi. I'm working on my US federal taxes for 2026. I live in South Carolina. From WagerMints, checked November 3, 2026: - Kalshi's Documents page says it does not report profits and losses to the IRS. - Forms it may send: 1099-INT for interest, 1099-MISC for credits and rewards, 1099-B or 1099-DA for crypto transfers. - Its Profit and Loss statement uses first in, first out, is split by year and updates on the first morning of each month. - Reward credits only appear in the activity export, not the trades export. - The IRS has published no guidance on how event contracts are taxed. Four ways traders report this: 1. Capital gains: Form 8949 and Schedule D, short- or long-term by holding period. Net losses offset up to $3,000 of other income a year, and the rest carries forward. 2. Section 1256: Form 6781, 60% long-term and 40% short-term however long I held. Positions open on December 31 count as sold at that day's value. Disputed: Camuso and Mukherjee (Tax Notes Federal, June 2026) conclude it isn't available, White & Case argues for it, and the CFTC's October 2026 proposal to call event contracts swaps cuts against it, because Section 1256 excludes swaps. 3. Ordinary income: net result on Schedule 1, line 8z. 4. Gambling: winnings on Schedule 1, line 8b. Losses only on Schedule A if I itemize, only up to winnings, and only 90% of them from 2026. South Carolina: South Carolina taxes gambling winnings and prediction market profits as income (1.99% to 5.21% (2026)). Gambling losses only reduce your state tax if you itemize, and only up to your winnings.

How to answer: - Say which links you opened, and never describe one you didn't open. If one fails, use the facts above and say so. - Mark each point [linked source], [general tax rule] or [unsettled]. - Put the methods side by side in one table for my year, and state any number you assume. - Don't pick a method for me. End with questions for a CPA or enrolled agent, then anything you need from me.
