Crypto Capital-Gains Tax Estimator
Crypto capital-gains tax depends on your country and how long you held the asset. In the US, gains on crypto held 12 months or less are taxed at your ordinary rate (10-37%); held longer, at the preferential 0/15/20% long-term rates. The UK taxes gains above a £3,000 (2025/26) allowance at 18% or 24%. Canada includes 50% of the gain in income at your marginal rate. Australia gives a 50% CGT discount after 12 months. Pick your country below for a 2026 estimate. This is an estimate, not tax advice.
How it works
Select your country, then enter your cost basis, sale proceeds, how many months you held the asset, and your other taxable income for the year (which decides your marginal bracket). The estimator applies that country's 2026 rules.
The model covers the common single-individual investor case. It excludes US state tax and the 3.8% Net Investment Income Tax, Australia's Medicare levy, and Canadian provincial tax. Always confirm with the relevant authority — IRS, HMRC, CRA or the ATO — or a qualified adviser. Estimates, not financial or tax advice.

Frequently asked questions
Is swapping one coin for another taxable?
Yes in the US, UK, Canada and Australia — a crypto-to-crypto swap is a disposal of the first asset and triggers a capital gain or loss, even though no fiat is involved.
How does the tool decide short vs long-term?
By the holding period you enter. The US and Australia use a 12-month threshold; the UK and Canada do not distinguish by holding period in the same way.
Does it include state, provincial or surcharge taxes?
No. It estimates the federal/national capital-gains component only. US state tax, the 3.8% NIIT, Canadian provincial tax and Australia's Medicare levy are excluded.
Are these the official 2026 rules?
They reflect researched 2026 parameters (IRS brackets, the UK £3,000 allowance, Canada's confirmed 50% inclusion rate, and Australia's 50% discount), simplified for an individual. Verify with the cited authority before filing.
