Basic Or Higher Rates And Rules Of Capital Gains Tax On UK property
Want a relief from tax on the overall income you generate by selling a property? Well, as a uk or non-UK resident, it is a legal obligation that you need to pay a basic capital tax rate on 2nd homes, buy-to-let, or investment property. But, if you want ease, there are also many legal ways to reduce the amount, such as letting, private residence, or allowable expenses relief. This complete guide on the Capital gains tax on uk property by Real Estate Agents London clearly explains the relief criteria and timeline to report the tax submission to HMRC.
What is Capital Gains Tax on UK Property?
This is the tax that residents need to pay on the asset sale after its value has increased over time. Moreover, they only complete tax obligations on the gain they generate from selling, not on the allowable expenses and general ongoing fees. For example, if you bought a house for £150,000 and sold it for £250,000 after a value rise, you would pay CGT on the £100,000 gain without including any allowed costs.
Plus, this basic tax does not apply to residents living in their main home; in fact, it only applies to second homes, buy-to-let, business assets, or investment properties. However, not only uk residents, but even individuals living abroad also fall under the legal uk CGT tax implication category. After fulfilling your responsibilities, it is better to inform HMRC within the time limit of 60 days to avoid any penalties or fines.

Capital Gains Tax for UK vs Non-UK Residents
UK residents pay Capital Gains Tax on any property they sell, whether it’s in the UK or abroad. Non-residents only pay CGT when they sell property in the UK, but they must still report the sale to HMRC(Her Majesty’s Revenue and Customs) within 60 days.

How to Avoid Capital Gains Tax on Property in the UK?
There are several legal ways to sell a UK property to reduce Capital Gains Tax, including Private Residence Relief, Lettings Relief, claiming allowable expenses, transferring the property to a spouse, and using your annual CGT allowance. Here are the commonly used methods explained below:
Private Residence Relief
If you own a primary residence, then by this method you can reduce or remove your CGT. Not only this, but If you lived in your property part-time, you may have a chance to get relief, including the final 9 months of ownership, even after moving out.
Lettings Relief
By this legal way, individuals can minimise the tax rate upto £40,000 if they are living and renting a small portion of their home at the same time.
Allowable expenses
You can reduce your taxable gain by subtracting costs you paid while buying or selling the property. These expenses include:
- Solicitors’ and estate agent fees
- Stamp duty
- Improvement costs (e.g., extension or new kitchen)
- Maintenance costs (like painting or repairs) do not count.
Spousal transfers
You can transfer a property to your spouse or partner without paying any CGT. This helps many couples use two CGT allowances and sometimes lowers the tax rate if one partner is in a lower tax band.
Using your annual CGT allowance
Every person gets a small tax-free CGT allowance each year (e.g., £3,000) from the uk government that they can use to avail relief from taxable gain.

UK Capital Gains Tax Rates Criteria
Here are the tax rates according to basic, higher, or property-specific, which also depend on your rental income.
| Basic-rate | Taxpayers pay 18% CGT on profits from selling a residential property. |
| Higher-rate or additional-rate | Taxpayers pay 24% CGT on property gains. |
| Property-specific rates | The CGT rates for residential property are higher than for other assets because the government treats property gains differently. |

How to Report and Pay Capital Gains Tax on UK Property?
HMRC requires individuals on which CGT applies to inform them within 60 days after selling any type of property. This is done through the online CGT service, where you submit your gain and make the payment on time to avoid penalties.
60-day reporting rule
You must pay within 60 days of completing the sale of a UK residential property. Missing the deadline can lead to fines and interest.
Online submission
You can report your gain using the HMRC online CGT service through a Government Gateway account. If you can’t use the online system, you’ll need a paper form, which takes longer.
Payment timeline
CGT must be paid at the same time you submit your 60-day report. HMRC gives you the payment details after you file the return.

Final Thoughts
Capital gains tax on UK property applies to second homes, buy-to-let, or inherited properties, not your home, in which you live. By using reliefs like Private Residence Relief, Lettings Relief, allowable expenses, and your annual CGT allowance, you can reduce the tax you owe.

FAQs About Capital Gains Tax on Property UK
Private Residence Relief is a rule that helps you understand when you pay Capital Gains Tax or not. If you live in your home, you don’t pay tax; however, if you rent it out and don’t live there, you may get the relief.
For calculating capital gains tax, subtract the price of the property you bought from the price you sold it. Then take away costs, like legal fees or improvement costs, to get a taxable gain. After that, you pay tax on your remaining amount using your CGT rate based on your income level.
If you don’t live in the UK and are selling your property, then still have to pay capital gains tax in the UK. Even if you are living abroad full-time, you must report and pay the tax within 60 days of selling your property.
This depends on your country’s tax rules because many countries tax you based on your worldwide income and profit from selling your property. However, some countries have tax agreements with the UK to stop you paying tax twice, so it’s best to check your local tax rules.
You have to pay Capital Gains Tax on things you sell for a profit, such as a second home, rental property, or investment property. CGT also applies to valuable items like shares, antiques, or art if they increase in value. Your main home is usually exempt unless special rules apply.
The 6-year rule treats your property as a main home upto 6 years, even if you are not living in it, as it was your main home before you moved out. So you don’t pay capital gains tax during that period. This is for those people who rent out their property for a short time and plan to return later.
From 2025, Capital Gains Tax rates on most assets will increase, with higher rates for non-residential property, shares, and business assets. Business Asset Disposal Relief will also be reduced, meaning more tax on business sales. Residential property rates (18% for basic, 24% for higher) stay the same, but planning is important to avoid paying extra.
