Selling a rental property: capital gains tax

Updated 8 November 2026

With tax on rental profits rising, more landlords are thinking about selling. Capital gains tax can take a big slice, and the deadlines are tight.

The basics

  • Rates: 18% within your basic-rate band, 24% above it.
  • Annual exempt amount: £3,000 per person.
  • Deadline: report and pay within 60 days of completion.

What affects the bill

The gain is the sale price less what you paid, buying and selling costs, and improvements. Who owns the property, when you sell and your other income all change how much tax you pay.

Selling as part of a bigger plan

Selling some properties can reduce borrowing and Section 24 pressure on the rest, or fund other plans. It's worth looking at the whole portfolio before selling anything.
