If you bought, sold, swapped, staked, or received crypto in 2025, you likely owe taxes in 2026. Here's every deadline you need to know.
US Tax Deadlines (IRS)
April 15, 2026 — Individual tax return due (Form 1040). Report all crypto transactions on Form 8949 and Schedule D. This includes:
- Every sale or swap (including crypto-to-crypto)
- Staking and mining income (reported as ordinary income)
- Airdrops received (taxed at fair market value when received)
- DeFi yield and lending interest
October 15, 2026 — Extended filing deadline (if you filed Form 4868 by April 15).
Important: Filing an extension does NOT extend the payment deadline. You must estimate and pay taxes owed by April 15 to avoid penalties.
What forms do you need?
| Form | Purpose |
|---|---|
| Form 8949 | Report each individual crypto transaction |
| Schedule D | Summary of capital gains/losses |
| Schedule 1 | Staking, mining, airdrop income |
| Schedule C | If you mine or stake as a business |
UK Tax Deadlines (HMRC)
January 31, 2027 — Self Assessment deadline for the 2025-26 tax year. Capital Gains Tax allowance for crypto is £3,000 (down from £6,000 in prior years).
Canada Tax Deadlines (CRA)
April 30, 2026 — Individual tax return due. Crypto is treated as either capital gains (50% taxable) or business income (100% taxable) depending on your trading activity.
Australia Tax Deadlines (ATO)
October 31, 2026 — Individual tax return due (or later if using a registered tax agent). CGT discount of 50% applies if you held crypto for more than 12 months.
How to prepare
- Gather all your transaction records — export CSVs from every exchange and wallet you used
- Use crypto tax software — tools like CoinTracker, Koinly, or TaxBit can automatically calculate gains and generate tax forms
- Check for tax-loss harvesting opportunities — you may be able to offset gains by selling losing positions before the deadline
- Review wash sale implications — check if any of your losses might be disallowed under wash sale rules
- File on time — late filing penalties compound quickly
Common mistakes
- Forgetting crypto-to-crypto swaps — swapping ETH for SOL is a taxable event
- Missing DeFi transactions — providing liquidity, claiming rewards, and bridging can all create tax events
- Using the wrong cost basis method — FIFO vs LIFO can dramatically change your tax bill (use our Tax Preview tool to understand the impact)
- Not reporting staking rewards — the IRS considers staking rewards as income when received
