How To Avoid Capital Gains Tax (UK) On Rental Property 

When selling a property in the UK, landlords often face the challenge of paying capital gains tax (CGT) on the profits made. While this can sneak up on you and feel like a nasty surprise when you’re hit with a big bill, there are a range of strategies and reliefs available to help reduce or even avoid this tax liability. 

This guide explores actionable tips and key information on how to avoid capital gains tax (UK), while also exploring key reliefs such as Private Residence Relief and Letting Relief.

Understanding Capital Gains Tax on UK Property

Capital gains tax (UK property) rules apply when you sell a property that is not your main residence, such as a rental or investment property. The taxable gain is the difference between the sale price and the property's original purchase price, accounting for allowable expenses.

For the 2024/25 tax year the capital gains tax rates are:

• If you’re a basic rate tax payer with an income of £50,270 or less, the rate is 18% on gains. 
• If you’re a higher rate tax payer with an income of £50,271 or more you’ll pay 28% on gains.

Being aware of available reliefs and allowances can significantly reduce your liability for capital gains tax on rental property or investment property.

How to Avoid Capital Gains Tax (UK)

To legally reduce or avoid CGT on property sales, consider the following strategies:

1. Utilize Private Residence Relief

Private Residence Relief (PRR) is the most effective way to reduce capital gains on rental property if the property was your main home. 

• The property has to have been your primary residence during your ownership.
• PRR also covers the last 9 months of ownership (even if you're not living there during that period).

When it comes to PRR, certain absences are treated as periods of residence, as long as you have lived in the property before and after the absence:

• Up to 3 years for any reason
• Up to 4 years, if required to work elsewhere in the UK or abroad
• Any period if working abroad

By ensuring the property qualifies as your main residence, you can significantly reduce or eliminate CGT liability.

2. Letting Relief: Reducing Capital Gains on Rental Property

If you've rented out a property that was once your main residence, you may be eligible for Letting Relief. This relief can reduce your taxable gain by up to £40,000. Some criteria must be met to qualify:

• The property must have been your primary residence at some point.
• You must have rented out part or all of the property as residential accommodation.

Letting Relief is calculated as the lowest of:

• The amount of PRR already claimed
• £40,000
• The amount of gain attributable to the letting period

Combining PRR and Letting Relief can substantially reduce CGT on a property that has been both your home and a rental.

3. Take Advantage of Your Annual Exemption

Every taxpayer is entitled to an annual CGT exemption (£3,000 for 2024/25). To maximize this:

• Time Your Sales: You can sell assets across multiple tax years, taking advantage of the separate exemptions that apply to each year. 
• Transfer Assets: Gifting property to a spouse or civil partner doubles the exemption because each person receives their own allowance.

Some proactive planning around the annual exemption can lead to major savings. 

4. Consider Timing and Ownership

Your property sale timing and ownership structure can affect CGT greatly:

• Sell During Low-Income Years: Though this is not always practical, selling property in a year when your income is lower will qualify you for the basic rate of 18% CGT rather than the higher rate of 28%.
• Joint Ownership: Buying jointly with a spouse or civil partner effectively doubles your CGT allowance, as it allows both of you to use your separate allowances. 

Reporting and Deadlines

As a landlord, understanding your financial reporting obligations needs to be your number one priority. When selling a property, any taxable gain must be reported to HMRC and paid within 60 days of the sale completion. Late submissions may incur penalties and interest, so staying organized is essential. 

Here’s some tips to follow:

• Plan The Timing of Your Sale: Selling in a tax year in which your income is lower may place you in a lower tax band. 
• Transfer Property Ownership: Passing your property to a spouse/civil partner can double the available CGT allowance and reduce the tax rate.
• Track All Improvement Expenses: Keep records of improvement expenses, such as renovations to reduce your taxable gain.

How To Avoid Capital Gains Tax On Rental Property In The UK: FAQ

Q: How long do I need to live in a property to avoid capital gains tax in the UK?

A: It must be your primary residence during the entire ownership period for full private residence relief. But certain absences are allowed without losing the relief - up to 3 years without cause, and longer if required by employment. 

Q: Will moving back into my rental property mean I can avoid CGT?

A: Moving back into a property can cause it to be classed as your primary residence and in turn, help you get PRR. Yet HMRC requires evidence of genuine residence - so short-term occupation will likely not suffice.

Q: Is Letting Relief still available?

A: There are certain conditions under which you can claim Letting Relief, mainly if you shared accommodation with your tenant. The rules have become stricter over the years, so it’s advisable to consult a tax professional to determine eligibility. 

Q: How does passing property to a spouse affect CGT?

A: Transferring property to a spouse or civil partner usually avoids CGT and allows the recipient to use their CGT allowance on the sale, effectively doubling the tax-free amount.

Q: Are there other reliefs available to reduce CGT on property?

A: Other reliefs such as the Business Asset Disposal Relief, may apply in certain circumstances, for instance, if the property was used for business purposes.
