A UK residential sale with tax to pay must be reported and paid within 60 days of completion. For a sale completing today, that window runs to about 5 November 2026.
On these figures there is no capital gains tax to pay, so a UK resident does not need to file the 60-day property return. A non-resident must report a disposal of UK property whether or not any tax is due.
This is an estimate for general information only, not tax, legal or financial advice. Tax rules are complex and depend on your circumstances, and figures may not reflect the latest changes. Confirm your position with HMRC or a qualified tax adviser before acting. The terms of use set out the limits of this estimate and of our liability.
Your figures are worked out in your browser. They are not sent to us or stored.
Which country are you selling in?
One engine, localised to each country's rules and currency. A country appears here only once its rates are verified from the authority.
Which situation applies to you?
Most tools return one generic number. These start from the situation you are in, because the reliefs and the deadlines depend on it.
How is the estimate worked out?
The same three steps in every country. The page shows each one, with the figures, so the result can be checked line by line.
Work out the gain
Sale price, less what was paid, less the allowable costs of buying, selling and improving. This is the figure the tax is charged on, not the sale price.
Apply the reliefs
Main residence relief where the property was a home, the annual exemption, and any country-specific discount such as Australia's 50 per cent or the US home-sale exclusion.
Tax what is left
At the country's rates, stacked on other income where the rules require it, with the reporting deadline shown next to the result.
Where do the figures come from?
Rates are taken from the tax authority's own pages, stored with the date they were checked, and linked on every calculator. On the case HMRC publishes, the UK engine returns the same figure, and the rate split follows the GOV.UK method.
How we calculateRates from the source
Every figure is pulled from the official tax authority and dated on the page. No numbers from memory.

Common questions
How much capital gains tax will I pay when I sell a property?
It depends on the gain, not the sale price, and on the country. A higher-rate UK taxpayer selling a second home bought for £200,000 and sold for £300,000 pays an estimated £23,280 on the £100,000 gain. Enter your own figures in the calculator above to see the estimate for your sale.
Do I pay capital gains tax when I sell my main home?
Usually not, though the relief has a different name in each country: Private Residence Relief in the UK, the Section 121 exclusion in the United States, Principal Private Residence relief in Ireland, the main residence exemption in Australia and the principal residence exemption in Canada. Each has its own conditions, and each calculator applies the one for that country.
Which country has the lowest capital gains tax on property?
It depends on the size of the gain, how long the property was held and the seller's other income, so no single country is always cheapest. The comparison page prices the same sale in all five countries side by side so the difference can be seen rather than guessed.
Are these figures accurate enough to rely on?
Every rate is taken from the tax authority's own published page, stored with the date it was checked, and linked on the page that uses it. On the case HMRC publishes, the UK engine returns the same figure, and the basic-rate split follows the method set out on GOV.UK and is locked by two worked cases in the test suite. That is one example checked, not a guarantee for every situation. The results are estimates for general information and are not tax advice, and a qualified adviser should be used for a decision.
Is anything I type sent anywhere?
No. Every calculation runs in your own browser. The sale price, purchase price and income you enter are never transmitted and never stored, and the site loads nothing from a third party.
