Profits And Losses: Capital Gains Tax In The UK Property Market

Entry Of Building With Transparent Glass Door

When selling residential property at a profit in the UK, capital gains tax (CGT) is payable on the increase in value achieved over your ownership period. For investment properties, CGT applies to any gains realised. Understanding CGT rates, allowances, exemptions and payment processes is essential for vendors maximising returns. This guide explains how CGT operates on property sales, advising on compliant reporting while utilising reliefs to mitigate tax payable.

Capital Gains Tax Overview

CGT basics:

  • This applies when you sell a property at a higher price than the original purchase cost.
  • Tax levied on the capital gain (profit) resulting from the increase in property value.
  • Gains above the annual CGT allowance are taxed, currently £12,300.
  • Property, except main residences, are also subject to an 8% CGT surcharge.
  • The tax rate depends on the vendor’s income tax band – from 10% to 28% plus a surcharge.
  • CGT reporting and payment are due within 60 days of completion via self-assessment.

Significant liabilities can arise so competent tax planning is vital.

Calculating Your Property’s Capital Gain

Accurately assessing profit:

  • Obtain records evidencing the original purchase price and transaction dates.
  • Deduct the purchase price, including taxes and transaction fees, from the final sold price.
  • Account for improvements that enhance capital value by keeping detailed records of major works undertaken.
  • Consider partial business use if workspace included, applying for CGT reliefs.
  • Factor in periods of vacation where the property was not a main residence.

Careful gain calculations avoid incorrect CGT underpayment penalties.

Claiming Your Annual CGT Allowance

Use allowances to shelter gains:

  • The annual exemption for 2022/23 is £12,300 per person.
  • Allowances apply to all asset classes, not just property sales.
  • Unused allowance rolls over only for spouses or civil partners.
  • Make exempt gift transfers to spouses or civil partners to double the allowance.
  • CGT paid on gains beyond the threshold at normal applicable tax rates.

Organise your tax affairs to utilise all available annual allowances.

Understanding CGT Implications On Second Homes

On second homes like holiday lets, CGT complexity increases:

  • Periods used as your residence still get main residence relief.
  • Periods let out are subject to CGT after allowances.
  • Apportion gain periods into exempt and taxable portions.
  • Keep detailed logs of usage and rental periods.
  • Apply “letting relief” to discount CGT by up to £40,000.
  • Factor in any Furnished Holiday Letting tax benefits claimed.

Meticulous records are vital on second homes to accurately calculate reliefs.

Obtaining Full Main Residence Relief

No CGT is payable on sales of your primary home:

  • Must have been sole or main residence throughout ownership. Holiday periods are ignored.
  • Can claim relief even if moving into a care home.
  • Periods away for work still qualify if the main home.
  • Delays in moving in due to renovations or building works do not invalidate future relief.
  • Letting exemptions available for temporary absences like military postings.

Main residence status secures full CGT exemption for most homeowners.

Maximising Private Residence Relief

When selling after vacating your primary home:

  • The relief applies automatically for the final 18 months of ownership after moving out.
  • Letting is allowed within this period while still preserving the relief.
  • Moving abroad or into care does not invalidate the final 18 months of relief.
  • But move and sale must occur within the same tax year for continuous relief.
  • Keep the property well maintained – CGT levies on value at the point of permanent vacation.

Careful residence planning maintains this valuable relief.

Mitigating CGT On Property Gift Transfers

Gifting property also creates CGT charges but mitigation options exist:

  • Lifetime gifting raises CGT payable by the giver based on market value minus allowances.
  • Inheritance gifting means CGT forms part of the deceased’s estate tax liabilities.
  • Recipient receives gifted asset at their original base cost – their gain only accounts for growth during their tenure.
  • Transfer to spouse ensures no CGT as transfers between spouses are exempt.

Early gifts with gradual appreciation minimise eventual tax hits.

Reporting And Paying Your CGT Liability

Once the CGT owing is calculated:

  • Report and pay tax due within 60 days of property sale completion.
  • Report via self-assessment tax return alongside your income tax.
  • Pay CGT bill directly to HMRC – interest applies for late payment.
  • Keep records supporting your gain calculations for five years.
  • Seek professional tax advice if unsure – HMRC can impose penalties.

Settlement delays risk surcharges so observe deadlines diligently.


In the UK, capital gain tax on sale of property affects most property vendors making healthy profits on sales. Understanding allowable deductions, main residence exemptions and ownership apportionment ensures accurate liability calculations. Seeking tax expertise secures maximum reliefs and ensures compliance – oversights risk future penalties. With diligent documentation and competent advice, property owners can craft strategies to minimise tax impacts when selling. The result is protecting more hard-earned housing wealth.
