Tax reporting basics for Kalshi contracts

Kalshi contracts are binary event contracts with YES and NO sides, and each contract settles to either $1.00 or $0.00. For tax purposes, you generally report gains and losses from these contracts in the year of settlement based on your cost basis. Your cost basis is typically what you paid to acquire the contract, plus any fees allocated to the position. Because Kalshi settlements are in USD, you’ll track cash flows and the final dollar value of your positions in your accounting records.

Keep records of each trade: the contract ticker, the date acquired, the amount paid, the price at exit, any fees paid, and the settlement amount. If you held multiple Kalshi contracts tied to one event, aggregate the results by contract and by tax lot to support cost-basis calculations. Always refer to your accountant or Kalshi’s published rulebook for the exact treatment applicable to your tax situation.

What counts as taxable gains with YES/NO trades

Gains or losses on Kalshi YES and NO contracts are generally recognized when the contract settles. If you sell a contract before settlement, your gain or loss is the difference between your sale price and your cost basis. Some traders track realized gains separately from unrealized positions, especially when positions are rolled or rebalanced across events.

Transactions where you simply hold to settlement may result in ordinary income or loss, depending on how the tax code applies to your trading activity. The key is consistent tracking of purchase price, fees, and settlement proceeds, and categorizing posts in your tax software or ledger. When in doubt, consult a tax professional familiar with derivatives and event contracts.

Kalshi settlement mechanics and cost-basis impact

Settlement rules determine which side wins when a market closes, and the resulting cash flow is what you report. If you owned YES contracts priced at 30 cents and NO at 65 cents, your final P/L depends on which side resolves true. For cost-basis calculations, include the amount paid per contract plus any ancillary fees. If you realize a gain or loss, you’ll typically report it in the tax year the settlement occurs.

Because Kalshi is USD-settled and regulated, your broker or tax software may offer specialized fields for binary options and “derivatives” activity. Use those fields to tag Kalshi activity distinctly from other investment income to simplify filing and potential audits.

Practical steps for record-keeping and filing

Export your Kalshi trade history and reconcile it with your wallet or broker statements. Maintain a per-contract ledger with: ticker, lot size, purchase date, purchase price, fees, settlement date, and settlement amount. Use this data to calculate cost basis and taxable gains or losses by event and by contract. If you use KalshiArb’s pricing alerts or any automation, ensure you retain logs that show the entry and exit prices used for your tax lots.

Always review Kalshi’s settlement rules and disclaimers, and align your tax reporting with your accountant’s guidance to ensure compliance.
