5 Property CGT Planning Tips

  1. Use your annual CGT allowance: Each individual has a £3,000 tax-free allowance (2024/25). Couples can transfer property interests to use both allowances — saving up to £720 in CGT.
  2. Bed & ISA strategy: If selling other investments, consider selling and repurchasing inside an ISA to shelter future gains from CGT entirely.
  3. Nominate your principal residence: If you own more than one home, formally nominate which is your PPR within 2 years of acquiring the second property to maximise relief.
  4. Time your disposal: Disposing of property at the start of a new tax year (6 April) gives you a full year before CGT is due (31 January following the next tax year), improving cash flow.
  5. Offset capital losses: Losses on other disposals in the same tax year can be offset against property gains. Losses from previous years can be carried forward indefinitely — keep records.

CGT Rates on Residential Property 2024/25

From 30 October 2024, CGT rates on residential property are 18% for basic rate taxpayers and 24% for higher and additional rate taxpayers. Non-residential property and other assets are taxed at 10% / 20%.

How PPR Relief Works

If the property has been your main residence throughout ownership, the entire gain is exempt. For periods of partial occupation, the exempt portion is calculated as:
(months as main home + 9 final months) ÷ total months × gross gain

Reporting Requirements

Since April 2020, UK residents must report residential property disposals and pay estimated CGT within 60 daysof completion via HMRC's online service. The gain must also appear on the annual Self Assessment return.

Non-Residents

Non-UK residents are subject to Non-Resident CGT (NRCGT) on UK property disposals and must report within 60 days regardless of whether a gain arises. Different rules apply — seek specialist advice.
