🌊Sei Crypto Tax Calculator

Connect your Sei wallet address to Blockchain Smart Tax. We automatically import all your SEI 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 SEI, as property. Selling, trading, or swapping SEI triggers a taxable event. Receiving SEI as income (staking, airdrops, mining) is taxed as ordinary income at fair market value on the date received.

Taxable Sei events include: selling SEI for USD or stablecoins, swapping SEI for another crypto, using SEI to pay for goods or services, and receiving SEI as staking rewards, airdrops, or mining income. Transferring SEI 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. Sei staking rewards are taxed as ordinary income at fair market value when received. IBC (Inter-Blockchain Communication) transfers between your own wallets are not taxable, but our system auto-detects and classifies them correctly.

We classify Sei 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 Sei 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.

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.

SEI held for more than one year qualifies for long-term capital gains rates (0%, 15%, or 20% depending on income). SEI 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.

Most competitors like Koinly, CoinTracker, and CoinLedger do NOT support Sei. Blockchain Smart Tax is one of the only crypto tax platforms with native Sei integration — no CSV uploads required.
