Everything you need to know about Capital Gains Tax on property
What is Private Residence Relief?
Private Residence Relief (PRR) means you do not pay Capital Gains Tax on profits from selling your main home, as long as you lived in it as your main residence for the entire time you owned it. If you lived there for part of the time, you get proportional relief for those months, plus the last 9 months are always exempt.
What are the CGT rates on property?
For the 2025/26 tax year, Capital Gains Tax on residential property is 18% for basic-rate taxpayers and 24% for higher-rate and additional-rate taxpayers. These rates are higher than the standard CGT rates for other assets (10% and 20%). If your gain pushes you into the higher-rate band, you may pay a blended rate.
What is the last 9 months rule?
Even if you have moved out of your main residence, the last 9 months of ownership are always treated as if you were living there. This means the gain attributable to those months is covered by Private Residence Relief and is tax-free. This rule was reduced from 18 months in April 2020.
