Crypto Tax Estimator

Which method does this tool use for each country?

This tool uses one fixed method per country and applies it to the single gain you enter. The United States uses a bracket-rate lookup on income plus gain, the United Kingdom subtracts a £3,000 allowance and applies 18% or 24%, India applies a flat 31.2%, Canada includes 50% of the gain and applies a federal rate, and Australia optionally halves the gain before applying a marginal rate. Each country is a single flat lookup applied to the whole gain, not a progressive calculation across brackets.

How does the US calculation work, and what is the 3.8% add-on?

The tool subtracts the $16,100 single-filer standard deduction from your income, adds the gain, finds the bracket that total falls in, and applies that one rate to the entire gain: a short-term lookup of 10% to 37% or a long-term lookup of 0% (up to $49,450), 15% (up to $545,500) or 20%. These are the 2026 single-filer figures built into the tool, with no filing-status choice. The 3.8% add-on is tested on income plus the gain: it applies to the lesser of the gain or the amount by which that total exceeds $200,000. It uses the income you typed as a stand-in for modified adjusted gross income.

What does the UK figure include?

The tool subtracts a £3,000 allowance from the gain, floors the result at zero, and applies 18% if the income you typed is £50,270 or less and 24% if it is higher. It compares your gross income directly with that figure and does not work out taxable income first. The holding-period choice has no effect. The tool labels its allowance as the 2024/25 tax year, and rates and allowances change over time, so check HMRC for the year you are filing.

How are India, Canada and Australia handled?

India: a flat 30% plus 4% cess, 31.2% in total, whatever the holding period, with a note that 1% TDS under Section 194S may apply to transfers. Canada: 50% of the gain is treated as income and taxed at a single federal rate chosen from your income plus that amount, using the 2026 federal brackets built into the tool (14% up to $58,523, 20.5% to $117,045, 26% to $181,440, 29% to $258,482, 33% above); provincial tax is not included. Australia: the gain is halved if you choose long-term, added to your income, and taxed at one marginal rate from a table the code labels 2026-27 (15%, 30%, 37% and 45% above $18,200, $45,000, $135,000 and $190,000); these are the figures built into this tool, and the 2% Medicare levy is not included.

What happens with zero profit or zero income?

The boxes start at 10,000 profit and 75,000 income. Clearing either one counts as 0, so zero profit shows zero tax and zero income is used as zero. Negative entries are treated as zero, so the tool never shows a loss, and it cannot offset a loss against a gain. Enter only the net gain you want taxed.

Does the tool treat swaps, mining or staking differently?

No. It takes one number, your total gain, and has no input for the type of event. Whether a swap, a payment in crypto, mining or staking produces a gain or ordinary income in your country is not something this tool decides, and it does not calculate cost basis or match sales to purchases. You must work out the gain yourself and enter it.

Are these rates current, and is the result a tax bill?

Neither. Tax rules change every year, the tables in this tool are not updated automatically, and only the tax authority in your country or a qualified adviser can tell you what applies to you. The result is a rough estimate from a simplified method that ignores deductions, credits, other income types, state and local taxes, and penalties.
