Principal Private Residence Relief for Landlords: Can You Still Claim It?

Principal Private Residence (PPR) Relief exempts the part of a property gain that relates to the time you lived in the home as your only or main residence, plus the final nine months of ownership, so a landlord who once lived in a let property can still shelter a meaningful slice of their capital gains tax on a rental property in the UK. PPR Relief was never removed for landlords, but the way it interacts with letting was tightened from 6 April 2020, and many owners now overestimate the relief they will receive. Blue Tick Accountants, a Guildford-based UK tax advisory and accountancy practice, sees this misunderstanding cost sellers thousands each year. This guide explains who qualifies, how the relief is calculated, what happened to lettings relief, and how the 60-day HMRC reporting rule applies when you sell.

Key Takeaways

• Principal Private Residence Relief exempts the proportion of a gain that relates to periods you occupied the property as your main home, plus the final 9 months of ownership.
• Residential property gains in 2026/27 are taxed at 18% for basic rate taxpayers and 24% for higher and additional rate taxpayers.
• The capital gains tax annual exempt amount is £3,000 per person for the 2026/27 tax year.
• Lettings relief has, since 6 April 2020, only been available where the owner lived in the property at the same time as the tenant, capped at £40,000.
• A UK residential property disposal with tax to pay must be reported and the CGT paid within 60 days of completion.
• A property that was never your main home does not qualify for any Principal Private Residence Relief.

Can a landlord still claim Principal Private Residence Relief?

A landlord can still claim Principal Private Residence Relief, but only if the property was genuinely their only or main residence at some point during ownership. The relief has not been abolished for landlords. What changed is that letting relief, which used to extend PPR generously, was cut back sharply from 6 April 2020. If you bought a property purely as a buy-to-let and never lived in it, you receive no PPR Relief at all and the whole gain is chargeable. Where you lived in the home first and later moved out and let it, PPR shelters the qualifying occupation period and the final nine months, and the remaining let period is taxable. Establishing "main residence" is a question of fact: actual occupation, where post is delivered, and where you are registered on the electoral roll all support a claim.

How is Principal Private Residence Relief calculated in 2026/27?

Principal Private Residence Relief is calculated by multiplying the total gain by the fraction of ownership months that qualify for relief. The qualifying months are those you occupied the property as your main home plus the final 9 months of ownership, which are always exempt provided the property was your main residence at some stage. This time-apportioned method is the standard HMRC approach for a former home that was later let. For a CGT landlord who sells a former residence, getting the month count right is the single biggest factor in the tax bill. The final 9 month rule is generous, but it does not turn a long letting period into an exempt one, which is why selling a buy-to-let tax 2026 calculation rarely wipes out the gain entirely.

Worked example: selling a former home that became a rental

Consider a landlord who bought a flat in Guildford for £250,000 in April 2014, lived in it as their main home for 4 years, then let it for 8 years, and sold it for £410,000 in April 2026. The total gain is £160,000 over 144 months of ownership. The qualifying period is 48 months of occupation plus the final 9 months, giving 57 exempt months. PPR Relief is £160,000 multiplied by 57/144, which is £63,333. The chargeable gain is therefore £96,667. After deducting the £3,000 annual exempt amount, £93,667 is taxable. As a higher rate taxpayer, the CGT due at 24% is roughly £22,480. Allowable costs such as legal fees, estate agent fees and qualifying improvements would reduce this further.

What happened to lettings relief for landlords?

Lettings relief is now only available where the landlord shared occupancy of the property with the tenant during the letting period. Before 6 April 2020, lettings relief could exempt up to £40,000 per owner even where the landlord had moved out entirely, which made a large difference to buy-to-let sales. The reform removed that benefit for the typical landlord who lets a former home after moving on. The relief still exists at up to £40,000, but only for shared-occupancy arrangements such as taking in a lodger while continuing to live there. Most landlords selling a former main residence in 2026/27 will no longer qualify, so the calculation reverts to PPR plus the final nine months alone. This is the change most often missed. For a full overview of how these reliefs fit within the wider CGT picture, see our guide to capital gains tax on rental property.

How do you report and pay the tax within 60 days?

A UK residential property disposal that produces a taxable gain must be reported to HMRC, and the capital gains tax paid, within 60 days of the completion date. Reporting is done through HMRC's online UK Property Account, separately from the annual self-assessment return. Missing the 60-day deadline triggers automatic penalties and interest, even where the eventual gain turns out to be small. The gain is still included again on your self-assessment tax return for the year, with the 60-day payment credited against the final liability. A CGT landlord should therefore calculate the gain, PPR Relief and any allowable costs before completion, not months afterward, so the return and payment can be made on time.

Rent received while the property was let is taxed separately from the gain, as our guide to how rental profit is taxed sets out.

Frequently Asked Questions

Do I pay capital gains tax if I lived in my rental property before letting it?

You pay capital gains tax only on the portion of the gain relating to the period the property was let, not the period you lived in it. Principal Private Residence Relief exempts your occupation period plus the final 9 months of ownership. The remaining let period is chargeable at 18% or 24% in 2026/27, after your £3,000 annual exempt amount.

How many months of PPR relief do I get automatically when I sell?

You automatically receive relief for the final 9 months of ownership, provided the property was your only or main residence at some point. This 9 month period is exempt even if the property was let at the time of sale. It is added to your actual months of occupation when calculating the exempt fraction of the gain.

Can two people claim Principal Private Residence Relief on the same property?

Yes, a married couple or civil partners who jointly own a former main residence can each claim Principal Private Residence Relief on their share of the gain. Each also has their own £3,000 annual exempt amount for 2026/27. A couple can only have one main residence between them at any given time for PPR purposes.

Is lettings relief still worth £40,000 for landlords in 2026/27?

Lettings relief remains capped at £40,000 per owner in 2026/27, but only where you lived in the property at the same time as your tenant. A landlord who moved out entirely before letting no longer qualifies. Most buy-to-let sales of a former home therefore receive PPR Relief and the final 9 months only, with no lettings relief.

What records do I need to prove a property was my main residence?

You need evidence of genuine occupation, such as council tax records, utility bills, bank correspondence, and electoral roll registration for the relevant dates. HMRC treats main residence as a question of fact rather than intention. Keeping documents that show you actually lived there strengthens a Principal Private Residence Relief claim if HMRC asks for proof.

How Blue Tick Can Help

Blue Tick Accountants helps landlords calculate Principal Private Residence Relief accurately, apply the correct 2026/27 rates, and file the 60-day property return on time so no relief or deadline is missed. A short planning review before you exchange contracts can identify allowable costs and reliefs that materially reduce the tax on selling a former home. Head to our website and book a meeting now.

Conclusion

Principal Private Residence Relief still works for landlords, but only for the time a property was genuinely your main home, plus the final nine months. Since lettings relief now applies only to shared-occupancy arrangements, most former homes that were later let will carry a real capital gains tax bill in 2026/27. Calculate the exempt fraction, gather your allowable costs, and file the 60-day return before the deadline. Taking advice before completion, not after, is what protects the relief.
