Do You Pay Tax When You Sell Your House?

If you’re wondering if you pay tax when you sell your house, the short answer is: usually no, if it’s your main home. But there are important exceptions.

Selling a property can feel overwhelming. Between legal paperwork, timelines and negotiations, tax is often the biggest worry. In this guide, we explain clearly what tax you pay when selling a house, when Capital Gains Tax applies, what exemptions exist, and how to report it properly.

Understanding the rules early helps you plan better and avoid unexpected bills.

What Tax Do You Pay When Selling a House?

In most cases, you won’t pay tax when selling your main home. However, tax can apply in certain situations.

The main tax to be aware of is Capital Gains Tax. You may also need to consider Income Tax if the property has been used for business purposes.

Here are the key taxes to understand:

Capital Gains Tax (CGT)

You don’t normally need to pay Capital Gains Tax when you sell your main residence. Your property is usually exempt from CGT if all of the following apply:

• You’ve lived in the home as your only or main residence for the entire time you’ve owned it

• You haven’t rented out part or all of it (or used part of it exclusively for business purposes)

• The total grounds, including gardens and outbuildings, are 5,000 square metres (just over an acre) or less

If all of the above are true, you’ll qualify for Private Residence Relief and won’t have to pay CGT when you sell.

If one or more of these conditions doesn’t apply, you may need to pay some tax on part of the gain.

Income Tax

If you’ve rented out your home or used part of it exclusively for business, you may owe Income Tax on rental income or certain gains.

Inheritance Tax implications

If you’re selling an inherited property, Capital Gains Tax may apply. The gain is calculated based on the difference between the property’s value at the time you inherited it and the price you sell it for.

Inheritance Tax may already have been dealt with during probate, but that doesn’t remove the possibility of CGT if the property has increased in value since you became the legal owner.

For most homeowners selling their primary residence, Private Residence Relief means no CGT is due. However, inherited homes, second properties and buy-to-lets are treated differently.

How to Calculate Tax When Selling Your Property

If CGT applies, you calculate it based on the gain, not the full sale price.

The basic steps are:

1. Take the sale price.

2. Subtract what you originally paid.

3. Deduct allowable costs such as stamp duty, legal fees, estate agent fees, and qualifying improvements.

4. Subtract your annual CGT allowance.

The remaining amount is your taxable gain.

CGT rates for residential property are typically:

• 18% for basic rate taxpayers

• 24% for higher and additional rate taxpayers

Your income tax band affects which rate applies.

For example: Let’s say you bought a second property for £200,000 and later sold it for £300,000.

Your total gain would be £100,000.

You can deduct your Capital Gains Tax annual allowance (for example, £3,000 in the 2025/26 tax year, subject to change), leaving a taxable gain of £97,000.

If you’re a basic rate taxpayer, you could pay 18% on some or all of that gain, depending on how much of your basic rate band is unused.

If you’re a higher rate taxpayer, you’d likely pay 24% on the taxable gain.

At 24%, that would mean a CGT bill of £23,280 on a £97,000 taxable gain.

The exact amount you pay depends on your total income in that tax year and any allowable deductions, so it’s always worth speaking to a tax adviser if you’re unsure.

Common Exemptions and Reliefs

The good news is that there are a few exemptions to paying Capital Gains Tax when selling a property. The UK tax system includes several reliefs and exemptions designed to protect people selling their main home, or to reduce the tax owed in certain circumstances.

Understanding which reliefs apply to you can make a significant difference to your final tax bill.

Private Residence Relief (PRR)

Private Residence Relief is the most important exemption for homeowners. If the property has been your only or main residence for the entire period you owned it, you usually won’t pay any Capital Gains Tax when you sell.

This relief covers the gain made during the time you genuinely lived in the property as your main home. In most straightforward cases, this means no CGT is due at all when selling your primary residence.

However, if you have rented part of the home, used part exclusively for business, or lived elsewhere for extended periods, only part of the gain may qualify for relief.

Final 9 Months Relief

Even if you move out before selling, the final nine months of ownership are usually treated as if you were still living there.

This means that even if you buy a new home and sell your old one later, you may still qualify for relief during those final nine months. This rule helps prevent short gaps between moving out and completing a sale from triggering unnecessary tax.

Longer absences may still qualify for relief, but only under specific conditions.

Lettings Relief

Lettings Relief may apply if you rented out part of your home while living in it at the same time.

It no longer applies in the same way as it once did. Today, you must have shared occupancy with your tenant for this relief to be available. If you moved out completely and then rented the whole property, Lettings Relief is unlikely to apply.

When it does apply, it can reduce the taxable gain further, but it is subject to strict conditions.

Annual CGT Allowance

Each individual has an annual Capital Gains Tax allowance. This means you can make gains up to a certain threshold each tax year without paying CGT.

If you own the property jointly, both owners can use their own allowance. This can significantly reduce the overall taxable gain.

For example, if a couple sells a jointly owned rental property, they can split the gain between them and apply two separate allowances before calculating any tax due.

The 6 Year Rule for Main Residence

If you move out of your main home and rent it temporarily, you may still qualify for Private Residence Relief for up to six years of absence.

To qualify, the property must have been your main residence before you moved out. In most cases, you must also move back in at some point to claim the full relief, unless your absence was due to working elsewhere.

This rule is particularly relevant for homeowners who relocate for work or temporarily let their home before returning.

Do I Have to Tell HMRC If I Sell My House?

If no tax is due because the property was your main residence, you usually do not need to report the sale.

However, if you owe Capital Gains Tax, you must report the gain to HMRC within 60 days of completion and pay any tax due within the same timeframe.

Reporting and Paying Tax

If CGT applies, you must:

• Report the gain using HMRC’s online Capital Gains Tax on UK property service

• Submit the report within 60 days of completion

• Pay the estimated tax owed within the same 60-day period

Failing to report or pay on time can result in penalties and interest charges. If you’re unsure, it’s wise to speak to a tax adviser before completion.

Tips to Reduce Tax When Selling Your House

There are legitimate ways to reduce your tax bill:

• Ensure you claim all allowable costs and improvement expenses

• Use both partners’ annual CGT allowances if jointly owned

• Consider timing the sale across tax years

• Make sure you qualify for Private Residence Relief

• Keep clear records of purchase price, improvements and legal costs

Planning early is key. If you’re preparing to move, reviewing your tax position before listing can help you avoid surprises.
