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?

A UK resident must generally report and pay any Capital Gains Tax due on UK residential property within 60 days of completion. Non-residents have separate reporting rules even when no tax is due.

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 between the Inheritance Tax value and the later sale price, after allowable costs and reliefs. If the Inheritance Tax value is unknown, official guidance uses market value at the date of death.

How does joint ownership affect the calculation?

This calculator offers an equal 50:50 comparison and assumes identical taxable income. Each owner must calculate and report their own share using their own allowance and taxable income.
