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?

FormPurpose
Form 8949Report each individual crypto transaction
Schedule DSummary of capital gains/losses
Schedule 1Staking, mining, airdrop income
Schedule CIf 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

  1. Gather all your transaction records — export CSVs from every exchange and wallet you used
  2. Use crypto tax software — tools like CoinTracker, Koinly, or TaxBit can automatically calculate gains and generate tax forms
  3. Check for tax-loss harvesting opportunities — you may be able to offset gains by selling losing positions before the deadline
  4. Review wash sale implications — check if any of your losses might be disallowed under wash sale rules
  5. 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
