How PolyTaxes Generates Your Polymarket Tax Report
From wallet address to IRS-ready Form 8949, Schedule D, and TurboTax CSV in minutes — every trade verified on-chain.
PolyTaxes is an independent tax-reporting service. We are not affiliated with, endorsed by, sponsored by, or operated by Polymarket. We never ask for your Polymarket password, private keys, seed phrase, or any account credentials — only your public wallet address, which we use to read transactions from the Polygon public blockchain.
