1. Overview of Taxes When Selling a Property in the UK

When selling a property in the UK, several taxes may be relevant, depending on the circumstances. The most common taxes include:

  • Capital Gains Tax (CGT): Applied when you make a profit on the sale of a property that is not your primary residence.
  • Stamp Duty Land Tax (SDLT): SDLT is paid by the buyer when purchasing a new property, but it can indirectly affect sellers who are buying and selling simultaneously.
  • Inheritance Tax (IHT): If you sell an inherited property, it may trigger tax implications under IHT rules.
  • Income Tax: In some cases, selling property as part of a business or rental activity may result in Income Tax rather than CGT.

These taxes have specific reliefs and allowances, including Private Residence Relief (PRR) and Letting Relief, which are designed to reduce the tax burden for homeowners. Understanding when these taxes apply and how to reduce your liability is key to minimizing your tax bill.


2. Capital Gains Tax (CGT)

What is Capital Gains Tax?

Capital Gains Tax (CGT) is charged on the profit (or “gain”) you make from selling an asset that has increased in value. This tax applies to property sales unless the property is your main residence, which is generally exempt from CGT. However, second homes, buy-to-let properties, or investment properties are subject to CGT when sold at a gain.

Capital Gains Tax Exemptions

If the property you’re selling is your primary residence and has been throughout your ownership, you’re likely to qualify for Private Residence Relief (PRR), which exempts you from paying CGT. However, if the property has been partially used for business, rented out, or wasn’t your main home for the entire period, PRR will only cover part of the gain.

Calculating CGT on Property

To calculate CGT, follow these steps:

  1. Determine the sale price of the property.
  2. Subtract the original purchase price and any allowable costs (e.g., legal fees, improvement costs, or estate agent fees).
  3. Apply any reliefs (such as PRR or Letting Relief).
  4. The remaining amount is your taxable gain.

For example:

  • Sale price: £400,000
  • Purchase price: £200,000
  • Improvement costs: £20,000
  • Legal fees: £5,000
  • Taxable gain: £400,000 – (£200,000 + £25,000) = £175,000

If the property was your primary residence for only part of the time, or was let out, you’ll need to apportion the gain accordingly.

CGT Rates for Property Sales

CGT rates on property differ depending on your income tax band:

  • Basic rate taxpayers: 18% on property gains.
  • Higher and additional rate taxpayers: 28% on property gains.

Your CGT liability is added to your income for the year, so if your property gain pushes you into a higher tax band, you’ll pay the higher CGT rate on that portion.

Non-Resident CGT

If you’re a non-resident in the UK and sell a UK property, you must still pay CGT on the sale. Non-residents must report and pay CGT within 60 days of the sale. The tax is only applicable on gains made after April 2015 for residential properties or April 2019 for commercial properties.


3. Private Residence Relief (PRR)

PRR Eligibility and How It Works

Private Residence Relief (PRR) is designed to exempt homeowners from CGT on the sale of their primary residence. If the property was your main home for the entire ownership period, PRR typically exempts you from paying CGT on any gain.

Apportioning PRR

If you haven’t lived in the property throughout the entire ownership, or you’ve used part of it for business or rental purposes, PRR will only apply to the time you lived in the home. For example:

  • If you lived in the property for 80% of the ownership period, you’ll be exempt from 80% of the CGT.
  • The last 9 months of ownership are always treated as residence periods, even if you weren’t living there at the time of sale.

4. Letting Relief

Letting Relief Overview

Letting Relief is available to homeowners who have rented out their main residence at some point during their ownership. The relief applies to the portion of the gain related to the rental period and is capped at £40,000 or the amount of PRR, whichever is lower.

Limitations and Changes to Letting Relief

As of April 2020, Letting Relief is only available if the homeowner shared the property with the tenant during the rental period, significantly limiting its use. Previously, Letting Relief could be claimed more broadly, but these changes have restricted its applicability.


5. Stamp Duty Land Tax (SDLT)

Understanding SDLT When Selling and Buying Properties

While Stamp Duty Land Tax (SDLT) is primarily the buyer’s responsibility, it can affect sellers indirectly if they are purchasing another property simultaneously. SDLT is charged on the purchase price of a property above certain thresholds.

For example:

  • Up to £250,000: 0%
  • £250,001 to £925,000: 5%
  • £925,001 to £1.5 million: 10%
  • Above £1.5 million: 12%

SDLT for Second Homes and Additional Properties

If you are buying an additional property, such as a second home or buy-to-let, an extra 3% surcharge applies on top of the standard SDLT rates.

First-Time Buyers and SDLT

First-time buyers purchasing a property worth up to £500,000 can benefit from reduced or zero SDLT, depending on the property value.


6. Inheritance Tax (IHT)

Inherited Properties and Tax Implications

When you inherit a property, Inheritance Tax (IHT) may apply to the estate of the deceased, but not directly on the sale of the inherited property. IHT is charged at 40% on the value of estates above the nil-rate band of £325,000.

Selling Inherited Property

If you decide to sell an inherited property, Capital Gains Tax may apply on any gain made between the property’s value at the time of inheritance and the sale price. If you hold onto the property for a significant period, the gain could be subject to CGT when sold.


7. Income Tax and Property Sales

Income Tax for Professional Property Traders

If you are in the business of buying and selling property, HMRC may classify your activity as a trade, meaning profits will be subject to Income Tax rather than CGT. This distinction typically applies to property developers or those who buy properties specifically to renovate and sell.

Buy-to-Let and Rental Income

If you sell a buy-to-let property, CGT applies to the gain. However, rental income from the property is subject to Income Tax during the ownership period, and allowable expenses (e.g., mortgage interest, repairs) can reduce taxable income.


8. Reliefs, Allowances, and Exemptions

Annual CGT Allowance

Each individual has an annual CGT allowance, which is £6,000 for the 2023/2024 tax year. This allowance reduces the taxable gain from property sales. If two people own a property, both can apply their individual allowance to reduce the taxable gain.

Other Applicable Reliefs and Strategies

Some additional reliefs may apply in special circumstances, such as Entrepreneurs’ Relief if the property was used for business purposes. Careful tax planning can also reduce liability through options like gifting the property or transferring ownership within a trust.


9. Special Situations and Tax Considerations

Selling Property at a Loss

If you sell a property at a loss, you can offset the loss against any other capital gains in the same tax year or carry it forward to future years to reduce CGT on future gains.

Property Owned in Trusts

Properties held in trusts can have unique tax implications. Trustees are responsible for paying CGT when trust property is sold, and special rules apply to property owned through bare trusts or discretionary trusts.

Shared Ownership and Tax Implications

If you own a property with others, your share of any gain or loss is apportioned according to your ownership percentage. Each owner can claim their own CGT allowance and reliefs.


10. Reporting and Filing Taxes

Deadlines for Reporting Property Sales

If CGT is due on the sale of a property, you must report and pay the tax within 60 days of the sale. You’ll need to file a CGT return with HMRC and make the appropriate payment within this timeframe.

Record Keeping and Documentation

It’s essential to keep accurate records of property sales, including purchase and sale contracts, legal fees, and details of any improvements. These records will be required when calculating CGT and other taxes.


11. Tax Planning Strategies

Gifting Property to Family Members

You can reduce your tax liability by gifting property to family members, but CGT and IHT may still apply depending on the circumstances. Gifting property as part of inheritance planning can help reduce IHT on your estate.

Timing Your Sale for Tax Efficiency

Selling a property in a tax year when your income is lower can reduce your CGT liability, as gains are taxed based on your income tax band.

Using Trusts and Other Legal Structures

Setting up a trust or limited company to manage property can offer tax advantages in some situations, particularly for buy-to-let investors or those with multiple properties.


12. Common Mistakes and How to Avoid Them

Common mistakes when selling property include:

  • Failing to apply Private Residence Relief correctly.
  • Missing tax reporting deadlines, leading to penalties.
  • Overlooking the Letting Relief changes post-2020.

13. Conclusion

Selling a house in the UK comes with various tax considerations, primarily around Capital Gains Tax, Stamp Duty Land Tax, and in some cases, Inheritance Tax or Income Tax. Understanding the rules and reliefs, such as Private Residence Relief and Letting Relief, is crucial to minimizing your tax liability. By careful tax planning, utilizing allowances, and keeping accurate records, you can navigate the tax implications effectively and make informed decisions about your property sale. Always consider seeking professional advice for complex tax scenarios or significant financial transactions.
