Do I pay Capital Gains Tax when I sell my home?
Published 21 May 2026 · 6 min read · By Evren Ergin
Most people do not pay Capital Gains Tax when they sell their only or main home, because a rule called Private Residence Relief usually covers the whole gain. You can still owe the tax if the property was a second home, a buy-to-let, or somewhere you did not always live as your main residence.
TL;DR
- •Capital Gains Tax is a tax on the profit you make when you sell something that has gone up in value, and selling your only or main home is normally exempt.
- •Private Residence Relief is the rule that removes Capital Gains Tax on the sale of a home you have lived in as your only or main residence throughout the time you owned it.
- •Capital Gains Tax can apply when you sell a second home, a holiday home, a buy-to-let, a property with very large grounds, or a home you did not always use as your main residence.
- •For the 2026 to 2027 tax year the Capital Gains Tax annual exempt amount is £3,000, and gains on residential property are taxed at 18% or 24% depending on your income tax band.
If you are selling the home you live in, this is the question that worries many homesellers. The short answer is reassuring for most people. Selling your only or main home is normally free of Capital Gains Tax, and you usually do not even need to report it.
This article is general information, not personal tax advice. Tax depends on your own circumstances, so check the rules on gov.uk or speak to a qualified accountant before you act on anything here.
What is Capital Gains Tax?
Capital Gains Tax is a tax on the profit you make when you sell or dispose of something that has risen in value. You are taxed on the gain, which is the difference between what you paid and what you sold for, not on the full sale price.
It applies to assets such as property, shares and valuable possessions. Each tax year you also get a tax-free amount, called the annual exempt amount, before any Capital Gains Tax is due. For the 2026 to 2027 tax year that allowance is £3,000 for an individual, according to gov.uk.
Why is selling my main home usually tax-free?
The reason is a rule called Private Residence Relief. Private Residence Relief is a relief that removes Capital Gains Tax from the gain on a home you have lived in as your only or main residence throughout the period you owned it.
Gov.uk states that you get full relief and pay no Capital Gains Tax if all of the following apply: you have one home and have lived in it as your main home for all the time you owned it; you have not let part of it out, although having a lodger is allowed; you have not used part of it exclusively for business; the grounds, including all buildings, are less than 5,000 square metres, which is just over an acre; and you did not buy it just to make a gain.
When all of those conditions are met, the relief is automatic. You do not claim it, and you do not normally need to tell HM Revenue and Customs about the sale.
When can Capital Gains Tax still apply?
Capital Gains Tax can become due when a property is not fully covered by Private Residence Relief. This usually happens when the home was not your only or main residence for the whole time you owned it, or was not really your home at all.
- A second home or holiday home, because only one property can count as your main residence at any one time.
- A buy-to-let property, where the home was rented to tenants rather than lived in by you.
- A home you did not always live in as your main residence, for example a property you let out for a period before or after living there.
- A property with very large grounds, where the garden and grounds exceed the permitted area of 5,000 square metres.
- A part of your home used exclusively for business, such as a room turned permanently into a shop or office with no private use.
- A property you bought mainly to sell on at a profit, rather than to live in.
Gov.uk also notes that the final 9 months of ownership always qualify for relief, as long as the home was your only or main residence at some point. In limited cases, such as for a disabled person or someone moving into a care home, that final period can be 36 months.
What are the Capital Gains Tax rates for property in 2026 to 2027?
If a gain on residential property is taxable, the rate depends on your income tax band. Gov.uk states that for gains made from 6 April 2026, basic rate taxpayers pay 18% and higher rate taxpayers pay 24% on residential property gains.
Where a gain straddles the basic rate band, part of it can be taxed at 18% and the rest at 24%. The annual exempt amount of £3,000 is deducted before the rate is applied.

Will I pay Capital Gains Tax in my situation?
The table below gives a general guide to common situations. It is a starting point only, not a ruling on your case. The detail of your ownership history can change the answer, so confirm your own position on gov.uk or with an accountant.
Common selling situations and whether Capital Gains Tax is likely to apply
| Your situation | Is Capital Gains Tax likely to apply? |
|---|---|
| You are selling your only home, lived in throughout, normal-sized grounds | Normally no, full Private Residence Relief usually applies |
| You are selling a second home or holiday home | Often yes, only one property counts as your main residence |
| You are selling a buy-to-let property | Often yes, the property was let rather than lived in by you |
| You lived in the home, then let it out for a period before selling | Possibly, relief may cover only part of the gain |
| Your home has grounds larger than 5,000 square metres | Possibly, the gain on the excess land may be taxable |
| Part of your home was used exclusively for business | Possibly, the business part may not get full relief |
How and when do I report Capital Gains Tax on a property?
If you sell a UK residential property that is not covered by full relief and there is tax to pay, there is a tight deadline. You must report the gain and pay the tax using HM Revenue and Customs' Capital Gains Tax on UK property service within 60 days of the sale completing.
If your home is fully covered by Private Residence Relief, you usually do not need to report the sale at all. When you are unsure whether a sale is taxable, that is a moment to get advice rather than guess.
Do I pay Capital Gains Tax if I sell my only home?
Usually not. If you have one home, have lived in it as your main residence for the whole time you owned it, have not let part of it out beyond having a lodger, have not used part of it exclusively for business, and the grounds are under 5,000 square metres, gov.uk says Private Residence Relief gives full relief and no Capital Gains Tax is due. Check your own position on gov.uk.
Do I pay Capital Gains Tax on a second home?
Often yes. Only one property can count as your main residence at any one time, so a second home or holiday home is not normally covered by full Private Residence Relief. Any taxable gain above the £3,000 annual exempt amount is charged at 18% or 24% for the 2026 to 2027 tax year, depending on your income tax band. A qualified accountant can confirm your figure.
What if I lived in my home and later rented it out?
Private Residence Relief may then cover only part of the gain rather than all of it. The relief is generally worked out for the periods the property was your main residence, plus the final 9 months of ownership. The let period may produce a taxable gain. The calculation can be detailed, so gov.uk guidance or an accountant is the safer route.
Is this article personal tax advice?
No. This is general information about how Capital Gains Tax and Private Residence Relief usually work for homesellers in the 2026 to 2027 tax year. It cannot account for your own ownership history, income or circumstances. For a decision about your own sale, check the rules on gov.uk or speak to a qualified accountant before you act.
Where does this leave you as a seller?
For most people selling the home they live in, Capital Gains Tax is not part of the picture. Knowing that early lets you plan your sale around the things that do change your outcome: your asking price, your fees, and the agent you choose to handle it.
Selling starts with your decision, not anyone else's. You set the timeline, and you stay in control of who you speak to and when. That includes taking the time to compare agents properly before you commit to one.
