⬡Polygon Crypto Tax Calculator

Connect your Polygon wallet address to Blockchain Smart Tax. We automatically import all your POL transactions, classify trades, swaps, and transfers, then calculate your capital gains using your chosen cost basis method (FIFO, LIFO, or HIFO). You can download IRS Form 8949 and Schedule D when you're ready to file.

Yes. The IRS treats all cryptocurrency, including POL, as property. Selling, trading, or swapping POL triggers a taxable event. Receiving POL as income (staking, airdrops, mining) is taxed as ordinary income at fair market value on the date received.

Taxable Polygon events include: selling POL for USD or stablecoins, swapping POL for another crypto, using POL to pay for goods or services, and receiving POL as staking rewards, airdrops, or mining income. Transferring POL between your own wallets is NOT taxable.

Blockchain Smart Tax starts at $25/year for up to 500 transactions — roughly half the price of Koinly or CoinTracker. During our beta period, all features are free with up to 10,000 transactions. We never charge extra for DeFi, staking, or NFT transactions.

Yes. We auto-detect 70+ DeFi protocols including Uniswap, Aave, Curve, and more on Polygon. NFT buys, sells, and mints are also tracked. All DeFi and NFT transactions are included free — no upsells.

We classify Polygon staking transactions at the instruction level — native staking, liquid staking, delegation, redelegation, and reward claims are all detected automatically. Staking rewards are reported as ordinary income per IRS Rev. Rul. 2023-14. You can also toggle whether liquid staking (e.g., depositing into liquid staking protocols) is treated as a taxable swap or a non-taxable transfer.

Yes. Connect your Polygon wallet address for on-chain transactions, and import exchange history via CSV from Coinbase, Binance, Kraken, and 20+ other exchanges. Blockchain Smart Tax matches exchange deposits and withdrawals with on-chain transfers automatically.

stETH daily rebase rewards are automatically detected and reported as income. rETH and wstETH are non-rebasing tokens — gains are only realized when you sell or unwrap them. You can configure whether the initial liquid staking deposit (e.g., ETH → stETH) is treated as a taxable swap or non-taxable transfer in your tax settings.

Blockchain Smart Tax supports FIFO (First In, First Out), LIFO (Last In, First Out), and HIFO (Highest In, First Out). You can switch methods and instantly see how each one affects your tax bill. Starting in 2025, the IRS requires per-wallet cost basis tracking (Rev. Proc. 2024-28) — we handle this automatically.

POL held for more than one year qualifies for long-term capital gains rates (0%, 15%, or 20% depending on income). POL held for one year or less is taxed at your ordinary income rate (up to 37%). Blockchain Smart Tax automatically tracks your holding periods and classifies each disposal as short-term or long-term.
