In short: There's no minimum ownership period that removes capital gains tax in the UK. What matters is whether the property was your main residence. Private residence relief covers the periods it was your only or main home, plus the final nine months of ownership. Gains on other periods, such as when it was let, are taxable at 18% or 24% after the £3,000 annual exemption. UK residents must report and pay CGT on residential property within 60 days of completion.
