CGT Rates and Calculations
How Capital Gains Tax on property is calculated and what you pay
Capital Gains Tax is charged on the profit you make when you sell, give away, exchange, or otherwise dispose of a capital asset. It is not the total sale proceeds that are taxed, but only the increase in value between what you paid for the asset plus certain costs and what you receive on disposal. Deductible costs include the original purchase price, legal and surveyor fees on acquisition, genuine improvement costs.
From 6 April 2025, CGT rates on residential property are 18% for gains that fall within the basic rate band and 24% for gains taxed at the higher or additional rate. The annual CGT-free exemption is £3,000 per individual in 2025/26. For couples who jointly own property, both partners have their own exemption, sheltering up to £6,000 of combined gains. We calculate your likely CGT exposure before you sell, making sure you make full use of both owners’ annual exemptions and available reliefs.

Non-Resident Capital Gains Tax specialist advice for overseas landlords
Non-UK residents are subject to UK Capital Gains Tax on all disposals of UK land and property, whether residential or commercial. The 60-day filing obligation applies to all UK property disposals by non-residents, even where no gain arises.
Non-residents who have been non-UK resident for fewer than five complete UK tax years at the time of disposal may also need to consider the temporary non-residence rules, under which certain gains realised during a period of non-residence can be brought back into the charge to CGT in the year of return. We strongly recommend obtaining a professional valuation as at April 2015 for any property purchased before that date, as this can substantially reduce the chargeable gain.

Common Pain Points
The CGT Traps Property Owners must Avoid
Capital Gains Tax on property is full of complexity that catches out even experienced investors. These are the most common issues we resolve for our clients.
Missing the 60-Day Filing Deadline
Any disposal of a UK residential property with a taxable gain must be reported and the tax paid to HMRC within 60 days of the completion date, not the exchange date. An initial penalty of £100 applies automatically on the day the deadline is missed, with further daily penalties and tax-based penalties for longer failures.
Incorrect Private Residence Relief Calculations
PRR can completely eliminate the CGT liability on a property that has been your main home throughout ownership, but the calculation of qualifying periods including periods of absence and the final nine-month deemed occupation is complex. Incorrect calculations result in either overpaid or underpaid tax.
Overlooking the April 2015 Rebasing Option for Non-Residents
Non-residents who purchased UK property before 6 April 2015 can elect to rebase the acquisition cost to market value as at 5 April 2015. Without this election, the gain is calculated from the original purchase price, which could mean paying CGT on decades of pre-2015 appreciation.
Failing to Report NIL-Gain Disposals (Non-Residents)
Non-UK resident landlords must file a CGT return within 60 days of completing a UK property disposal even where no gain arises and no tax is due. Failure to file a nil return still attracts automatic penalties from HMRC.
Not Using Annual Exemptions for Jointly Held Property
Where property is held jointly by spouses or civil partners, both partners have their own annual CGT exemption of £3,000. Failing to ensure the gain is allocated between both parties means the second partner’s exemption is wasted entirely.

FAQS
Commonly Asked Questions about Capital Gain Tax
Do I have to file a CGT return even if no tax is due?
For UK residential property disposals by non-UK residents, yes. A return must always be filed within 60 days of completion even where no Capital Gains Tax is payable. For UK residents, the 60-day return is required only when a taxable gain arises. However, the disposal must still be reported on a Self Assessment return where relevant.
What happens if a company leaves the group within six years of an intra-group transfer?
Yes. Capital losses made in the same tax year are offset against gains before the annual exempt amount is deducted. Unused losses are carried forward indefinitely against future capital gains but must be reported to HMRC within four years of the end of the tax year in which they arose.
Does UK Property Tax Accountants handle both the CGT return and the Self Assessment return?
Yes. We manage the entire reporting process, including the 60-day standalone CGT return and the subsequent inclusion of the disposal in your annual Self Assessment return. Any CGT paid via the 60-day return is credited against your Self Assessment liability, and we ensure the two returns are fully consistent.
If I gift a property to my child, do I have to pay Capital Gains Tax?
Yes. A gift of property is treated as a disposal at market value for CGT purposes, regardless of the fact that no money changes hands. The gain is calculated as the difference between the market value at the time of the gift and the original acquisition cost. However, holdover relief may be available in some circumstances for example, where the property is a business asset or is being gifted into a trust allowing the gain to be deferred rather than triggered immediately. We assess the CGT and Inheritance Tax implications of any proposed gift before it is made.
Does Principal Private Residence Relief apply to a property I let out after living in it?
Yes, in part. Private Residence Relief covers the period during which the property was your main home, together with the final nine months of ownership regardless of whether you were still living there. Periods of absence can also qualify in certain circumstances, such as where you were working abroad or working away from home in the UK. Lettings relief, which previously sheltered up to £40,000 of gain per owner on properties that had been both a main home and a rental property, was significantly restricted in April 2020 and now applies only where the owner is in shared occupancy with the tenant.
