Frequently asked questions

What are the Capital Gains Tax rates on residential property?

For 2026/27, residential property gains are taxed at 18% to the extent they fit within your unused basic-rate income-tax band and at 24% above it.

What is the Capital Gains Tax Annual Exempt Amount?

The Annual Exempt Amount is £3,000 per individual for 2026/27. Equal joint owners can each use an allowance against their share of the gain, subject to their own circumstances.

When must UK property CGT be reported and paid?

UK residents generally need to report and pay Capital Gains Tax on a taxable UK residential property disposal within 60 days of completion.

Is my main home exempt from Capital Gains Tax?

Private Residence Relief can exempt the full gain where the property was your only or main home throughout ownership and the conditions are met. Partial occupation and letting periods require a more detailed calculation.

How is CGT calculated on inherited property?

CGT may arise on growth in value between the relevant probate value and the later sale price, after allowable costs and reliefs. Inheritance Tax and Capital Gains Tax are separate.

How does joint ownership affect the calculation?

This calculator models equal 50:50 ownership by splitting the gain between two people, applying two Annual Exempt Amounts and assuming both owners have the same other taxable income.

This is an educational simplified estimate for UK residential property. It does not model partial Private Residence Relief, letting relief or complex multi-asset cases, and it is not tax advice. Check the current rules with GOV.UK or a qualified tax adviser.
