How these tools work
US tax on prediction market profit is unsettled. The IRS has issued no formal guidance on event contracts, so a trader faces three or four possible characterizations (short-term capital gain, Section 1256 60/40, gambling, ordinary income) and the venues do not issue a comprehensive trade-level 1099. The tools here fall into two kinds: estimators that show what each treatment costs, and software that builds the ledger a preparer needs.
For Polymarket the ledger problem is solvable by software because every trade is an on-chain USDC transaction: Awaken and CoinLedger both read a wallet address. For Kalshi there is nothing on-chain, so the path is the account export, which Manage Bankroll replaces with manual entry.
Choose an estimator first, a ledger second, and a preparer last. The estimator tells you how much the characterization decision is worth; that number decides how much to spend on the other two.
How to choose
- Run the TraderTax calculator (state included) or the COS Elite calculator (Kalshi, federal, four treatments) before buying anything, to see the spread between treatments for your numbers.
- For Polymarket, pick software that reads the wallet: Awaken lists Polymarket as an integration and describes redemption handling; CoinLedger documents wallet import in its guide. Verify how each labels a losing redemption in the free preview.
- For Kalshi, plan on the account export. CoinLedger recommends exporting quarterly; Awaken lists Kalshi but we could not confirm its import method.
- Count transactions before choosing a tier. Splits, merges and redemptions all count, and both Awaken and CoinLedger price by transaction volume.
- Use a bankroll tracker (Manage Bankroll) for the running P&L number, not for the return; it does not produce forms.
Questions about portfolio & tax tools
Does crypto tax software support Polymarket?
Awaken Tax lists Polymarket on its integrations page and describes categorizing buys, sells and redemptions from a wallet address. CoinLedger's guide describes wallet-address import and USDC cost basis reconstruction.
How are Kalshi winnings taxed?
No formal IRS guidance exists. TraderTax and COS Elite model the candidate treatments (short-term capital, Section 1256, gambling, ordinary income); TraderTax notes Kalshi issues 1099-INT, 1099-MISC and a narrow 1099-B but no comprehensive event contract 1099.
Is there a free prediction market tax calculator?
Yes. TraderTax's calculator covers Kalshi, Polymarket and Robinhood with state tax; COS Elite's covers Kalshi at the federal level. Both are free.
