Why CGT Planning is Now Critical
The moment you sell a property is a huge milestone.
You’ve likely invested years of effort, hard work, and capital. You deserve to keep the financial rewards of that investment.
The problem? Just as you complete the sale, HMRC steps in with the bill for Capital Gains Tax (CGT), often wiping out a significant portion of your hard-earned profit.
For UK property owners, this tax burden is heavier than ever: the tax-free allowance has been slashed to just £3,000 for 2025/26, and the tax rates are high.
Is there a legal way to push back? Absolutely.
Here are five HMRC strategies that every property owner should know.

Top Mistakes Companies Make with Capital Allowance Claims to make sure you never miss a deductible cost again.
1. Master Your Allowances: The £3,000 Tax-Free Shield
Every individual has an Annual Exempt Amount (AEA), a tax-free portion of capital gains. For 2025/26, this is just £3,000.
Tips to maximise it:
- Spousal Transfer: Transfer part of your property to a spouse or civil partner before the sale. Transfers between spouses are CGT-exempt, allowing both of you to use the £3,000 allowance effectively doubling your tax-free gain to £6,000.
- Timing Sales: If selling multiple assets, plan completions in different tax years to utilise the allowance fully.
2. Claim Every Allowable Cost to Shrink the Gain
CGT is calculated as:
Taxable Gain = Sale Price − (Original Purchase Price + Allowable Costs)
Include these costs:
- Acquisition: Stamp Duty Land Tax (SDLT), solicitor fees, valuation costs.
- Disposal: Estate agent fees, advertising, and selling-related legal costs.
- Capital Improvements: Additions or renovations that enhance value (extensions, loft conversions, new roof).
Tip: Routine maintenance like painting or fixing a boiler does not count.
Even a single £5,000 improvement could save up to £1,200 in tax at higher rates.
3. Utilise Capital Losses: The Tax Offset
Have you made a loss on shares or another property? These capital losses can offset gains from your current sale, reducing taxable income.
Example: A £10,000 loss on shares can reduce your property gain by the same amount, saving up to £2,400 in tax. Always report losses in previous tax years to claim this relief.
4. Maximise Private Residence Relief (PRR)
If the property was your main home, you may qualify for PRR, potentially exempting a large portion of your gain.
PRR covers the time when the property was your main or only residence. But HMRC also recognises certain “deemed occupation” periods when you weren’t living there but still qualify for relief.
These include:
- The last nine months of ownership, even if you’ve already moved out or rented the property.
- Any period spent working wholly overseas for your employer.
- Up to four years when required to live elsewhere for work within the UK.
- Up to three years for any reason (for example, a temporary relocation, family reasons, or a gap between selling and buying another home).
Important: These last three deemed-occupation periods only apply if the property is reoccupied as your main home after that absence.
PRR can make a huge difference, so track occupancy carefully.
5. Time the Sale to Split the Tax Burden
Strategic timing can save tax:
- Completing the sale after April 5 opens a new tax year’s £3,000 allowance.
- If jointly owned, combine with spousal transfer to maximise relief.
- This is particularly effective when the gain is large or allowances are already partially used.
Additional Tips
- Keep meticulous records: Invoices, receipts, and improvement logs.
- Review annually: Some assets continue to qualify for gains relief.
- Seek expert guidance: Specialists can uncover overlooked opportunities.
For official guidance, consult HMRC CGT guidance and PRR guidance.
Common Mistakes to Avoid
- Forgetting deadlines for reporting and paying Capital Gains Tax.
- Miscalculating allowable costs or improvements.
- Overlooking PRR or letting relief eligibility.
- Failing to utilise spousal transfers or timing strategies.
- Not consulting a property tax specialist for complex situations.
