US Crypto Tax Deadline 2026
The US federal tax deadline for the 2025 tax year is April 15, 2026. This covers all crypto capital gains and income earned between January 1 and December 31, 2025. An automatic 6-month extension moves the filing deadline to October 15, 2026 - but it extends time to file, not time to pay.

These are the dates US crypto filers need to track for the 2025 tax year filing season.
- January 31, 2026: W-2s and most 1099s due from employers and financial institutions.
- February-March 2026: Coinbase issues Form 1099-DA to eligible US customers for tax year 2025. This form reports gross proceeds - not your gains or losses.
- April 15, 2026: Federal tax return due. All tax owed for 2025 is due on this date. File Form 4868 on or before this date if you need an extension.
- October 15, 2026: Extended filing deadline for those who filed Form 4868 in April. Tax owed is still from April 15 - any shortfall has been accruing interest and failure-to-pay penalties since then.
What you need to file by the deadline
Crypto tax filing requires more than what your exchange sends you. Here is what to gather before you start.
- Complete exchange CSV - all time, not just 2025. FIFO cost basis requires your full acquisition history. Purchases made in 2021 affect the cost basis of tokens sold in 2025.
- Form 1099-DA from Coinbase if you received one - for reference only. It shows gross proceeds. You still need your own cost basis to calculate the actual gain or loss.
- Form 1099-MISC if you received over $600 in staking rewards, referral bonuses, or other income on Coinbase or Kraken during 2025.
- EVM wallet addresses if you used DeFi on Ethereum, Arbitrum, Base, or other chains. On-chain swaps, LP deposits, and staking events are all taxable.
- Form 8949 for capital gains - one row per disposal with description, acquisition date, sale date, proceeds, cost basis, and gain or loss.
- Schedule D to summarize short-term (held under one year) and long-term (held over one year) totals.
- Schedule 1 for staking rewards, mining income, and other crypto income that does not appear on Form 8949.
About Form 1099-DA for 2025
For tax year 2025, Coinbase issues Form 1099-DA to eligible US customers reporting gross proceeds from digital asset sales. This is a reporting improvement over prior years - but it is not a substitute for your own records.
The 1099-DA reports what you sold and for how much. It does not reliably report your cost basis, especially for assets acquired on other platforms, transferred in from external wallets, or purchased in prior years before the form existed. You still need to file Form 8949 with accurate cost basis for every disposition.
If your 1099-DA and your own calculation show different proceeds figures, investigate before filing. Cost basis mismatches between the IRS-reported proceeds and your reported gains can trigger notices.
How to calculate your crypto taxes before the deadline
FIFO across multiple exchanges and years is tedious by hand. Here is the fastest path from CSV to Form 8949.
- Download your complete transaction history. Log into each exchange and export your full CSV - select "All time." For Coinbase, this is under Taxes. For Binance, use Wallet > Asset History > Transaction Records. For Kraken, use Profile icon → Documents → Create Export (Ledger, full history, CSV) - the file arrives as a .zip.
- Upload to DYOR.tax and select United States. The FIFO engine calculates short-term gains (assets held under one year) and long-term gains (assets held over one year) automatically.
- Add wallet addresses if you used DeFi. EVM and Bitcoin wallet activity is merged with your exchange data. Every on-chain swap, LP transaction, and staking event is included.
- Review your free preview. See your total short-term gains, long-term gains, staking income, and top assets by P&L before paying. All figures are in USD.
- Download the full PDF report. It maps directly to Form 8949 columns and includes a separate staking income summary for Schedule 1. Enter the figures into TurboTax, H&R Block, or your tax professional's software.
What happens if you miss the April 15 deadline
Two separate penalties can apply if you miss the deadline: one for filing late and one for paying late. They compound independently.
- Failure to file: 5% of unpaid tax per month (or partial month), up to 25% of unpaid tax. This is the more expensive penalty - file on time or file an extension.
- Failure to pay: 0.5% of unpaid tax per month, up to 25% of unpaid tax. This accrues even if you filed an extension.
- Interest: The federal short-term rate plus 3%, charged daily on any unpaid amount from April 15.
- Extension eliminates the failure-to-file penalty but not the failure-to-pay penalty. File Form 4868 by April 15 if you cannot finish your return - then pay as much as you can estimate owing.
If you owe and cannot pay in full, still file and pay what you can. The IRS offers payment plans through its Online Payment Agreement tool. Penalty abatement may be available for first-time late filers with an otherwise clean compliance history.
Common reasons US crypto filers miss the deadline
- Assuming Form 1099-DA handles everything. It reports gross proceeds, not gains. You still need cost basis for every asset, which requires your full transaction history going back to initial purchase.
- Waiting for all exchange forms before starting. Start your calculation now using CSV exports - you do not need to wait for 1099s. If a form arrives later that differs from your own figures, reconcile then.
- Underestimating taxable event count. Every swap, not just every sale, is a taxable disposition. A DeFi user who made 200 swaps in 2025 has 200 Form 8949 rows, regardless of whether any showed a profit.
- Ignoring DeFi and wallet activity. Transactions on-chain are taxable even if no exchange issued a 1099. The IRS expects self-reporting of all digital asset activity, not just what appears on tax forms.
