Understanding Capital Gains Tax and Asset Improvements

When it comes to selling a capital asset in the UK, such as a home, investment property, or even a piece of art, understanding the implications of Capital Gains Tax (CGT) is crucial. One of the key aspects to consider is the role of improvements made to the asset and how they impact the CGT you might owe. This article aims to shed light on what improvements are allowed for Capital Gains Tax in the UK.

Understanding Capital Gains Tax and Asset Improvements

The Definition of an “Improvement”

In the context of Capital Gains Tax (CGT) in the UK, an 'improvement' refers to any alteration or addition made to a capital asset that enhances its value, extends its lifespan, or adapts it to a different use. Capital assets can include properties, pieces of art, or other valuable items that are subject to CGT when sold.

Improvements are significant for CGT calculations as the cost of these improvements can be deducted from the gain made when the asset is sold, potentially reducing the amount of tax payable. However, it's important to note that not all expenses incurred on an asset are considered improvements for CGT purposes.

In short, an improvement for Capital Gains Tax in the UK is a cost incurred on enhancing a capital asset that increases its value, extends its lifespan or adapts it to a different use. These costs can be deducted from the gain made on the sale of the asset, potentially reducing the CGT payable. However, it's crucial to understand the specific criteria that define an improvement and to keep detailed records of these expenses.

What Counts as an Improvement?

The first question that arises is, what exactly counts as an improvement? HMRC looks at improvements based on three things:

  1. Improvements Made on the Asset: Any improvements will need to be made to the asset itself to count. Any improvements outside of this aren’t allowable expenses. For example, if you own a classic car you’d like to sell and you have some of the paintwork restored, this can be included as an improvement. However, if you have repairs carried out on your driveway, as this is damaging the paintwork, these costs can't be included as they were not made on the asset.

  2. Value Enhancement: There's a difference between improvements and repairs. If you repair something to its original state, you can’t deduct this, but you can with anything that adds value. For instance, adding an extension to a property adds value and counts as an improvement, while repairs to damaged doors that don’t add any value are a repair and can’t be deducted.

  3. Value Retention at the Time of Disposal: Any improvements will need to retain their value to be deductible. For example, if you own a rental property and your tenants request some essential improvements like new flooring, these improvements need to retain their value when it comes to selling your asset. If the floors have worn away and need replacing again, they haven’t retained their value and wouldn't count as an improvement.

If your asset ticks all three boxes above, then it counts as an improvement and can be deducted from your Capital Gain to calculate any CGT.

Calculating Your Capital Gains Tax

Now that you’ve got to grips with improvements, you can calculate how much Capital Gains Tax you’ll need to pay. The total capital gains tax (CGT) you owe depends on two things: How much you earn in total and what type of assets you sell. Your overall earnings determine how much of your capital gains are taxed at - 10% or 20%.

The Role of Receipts in Claiming Capital Allowances

When it comes to claiming capital allowances for improvements, having evidence to support the expenses is crucial. If you do not have receipts for work that enhanced or improved the property, then including those costs as capital allowances has to be your decision. As per HMRC, without evidence to support the expenses, you cannot claim these against any gain.

In conclusion, understanding what improvements are allowed for Capital Gains Tax in the UK can help you make informed decisions when selling a capital asset. Always remember to keep a record of all improvements made to the asset, as these can significantly impact the amount of CGT you may need to pay.

What is the Difference Between an Improvement and Repair for Capital Gains Tax UK?

Understanding the difference between an improvement and a repair is crucial when calculating Capital Gains Tax (CGT) in the UK, particularly for landlords and property investors. These two terms, while seemingly similar, have distinct definitions in the realm of taxation and can significantly impact the amount of CGT payable upon the sale of a property.

Defining Improvements and Repairs

An 'improvement' in the context of CGT refers to any alteration or addition to a property that enhances its value, extends its lifespan, or adapts it to a different use. Examples of improvements include adding an extra bedroom, extending into the loft, or upgrading a kitchen with superior-quality units and appliances. These enhancements are considered capital expenditures and are typically deductible from the gain made when the property is sold, potentially reducing the amount of CGT payable.

On the other hand, a 'repair' or 'revenue expenditure' is what is incurred merely to preserve or maintain a property. This includes activities like painting, decorating, or replacing a damaged roof with a new one of similar quality. Unlike improvements, repairs do not add significant value to the property but merely restore it to its original condition.

The Importance of the Distinction

The distinction between improvements and repairs is important for two main reasons:

  1. Timing of Tax Relief: Tax relief for capital expenditure (improvements) is generally claimed only when the property is sold, under CGT. If the property is not sold for many years, tax relief can be a long time coming. Repairs, however, can be claimed in the year of expenditure, effectively immediately.

  2. Rate of Tax Relief: The rate of tax relief also differs. Income tax costs as much as 45% (for additional rate taxpayers) while CGT costs 28% at most; it is a maximum of 28% for residential property; which falls to 20% for commercial property. But this, in turn, means that the maximum relief for capital expenditure will be only 28% (or 20% for commercial property).

The Impact of Inflation

Given that property tends to be a relatively long-term investment, one should keep in mind that saving £10,000 'in today’s money' is worth more than saving £10,000 in 20 years’ time. This inflationary effect can impact the value of the tax relief obtained from improvements when the property is sold many years later.

The Role of the Asset

One of the key issues to consider with ‘capital vs revenue’ is: what is the asset that is being worked on? If the asset being worked on is attached to the property, such as a kitchen or a roof, the nature of the work (whether it's a repair or an improvement) can impact the overall value of the property and hence the CGT calculation.

In conclusion, the distinction between repairs and improvements is a significant factor in calculating Capital Gains Tax in the UK. While both involve the expenditure on a property, their impact on the value of the property and the timing and rate of tax relief differ. Understanding these differences can help property owners and investors make informed decisions about property maintenance and improvement, and optimise their tax position. It's always advisable to seek professional advice before undertaking significant property work to ensure the right approach for tax purposes.

What Expenses Can You Claim Against Capital Gains Tax?

Capital Gains Tax (CGT) in the UK applies when you sell, or dispose of, assets that have increased in value. It is the gain you make that is taxed, not the amount of money you receive. Understanding what expenses you can claim against CGT is essential in minimising your tax liability. In 2023, the following expenses remain claimable against your capital gains.

Purchase and Improvement Costs

When calculating your capital gains, you can deduct the costs associated with acquiring and improving your assets. This includes the original purchase price of the asset and costs directly linked to the acquisition, such as legal fees, stamp duty, and valuation or surveyor's fees. The cost of any improvements made to the asset that increases its value, such as an extension on a property, can also be deducted. However, routine maintenance and repair costs cannot be included.

Selling Expenses

Expenses directly related to the sale of your asset can be claimed. These may include marketing fees, agent's commission, legal expenses, and costs of obtaining a valuation for the sale. It's important to note that these must be actual selling costs, not costs related to the preparation for the sale. For instance, the cost of home staging would not be deductible.

Private Residence Relief

If the asset you're selling is your main home, you may be eligible for Private Residence Relief. This could potentially exempt you from CGT entirely or significantly reduce the amount you have to pay. However, there are specific criteria that must be met to qualify for this relief. For example, the property must have been your main residence for the entire period you owned it, and you must not have let out part of it or used part of it for business.

Lettings Relief

In the past, Lettings Relief was a valuable tool for reducing CGT when selling a property that had been both a main residence and a rental property. However, from April 2020, this relief has been restricted and now only applies in circumstances where the homeowner is in shared occupancy with a tenant. If this applies to you, it could provide significant savings.

Loss Relief

If you've made a capital loss in the same tax year as you've made a capital gain, you can offset this loss against your gain, effectively reducing your taxable gain. It's also possible to carry forward capital losses from previous years. However, it's important to report these losses to HM Revenue & Customs (HMRC), even if there is no tax to pay, so they can be used in the future.

Entrepreneurs' Relief

If you're selling or giving away your business, Entrepreneurs' Relief (now known as Business Asset Disposal Relief) could reduce your CGT. This relief can mean that you pay tax at a lower rate of 10% on all gains on qualifying assets. There are stringent conditions to meet, including being a sole trader or business partner and owning the business for at least two years before the sale.

Capital Gains Tax can be complex, and the rules change regularly. It's always advisable to seek professional advice when selling assets to ensure you understand all the reliefs and allowances you're entitled to. Remember, efficient planning and thorough record-keeping can significantly minimise your CGT liability. Ensure you keep all relevant receipts and documentation relating to your asset's purchase, improvement, and sale, so you're prepared when it's time to calculate your capital gains.

Why is it a Good Idea to Get Help from a Professional Tax Accountant for Capital Gains Tax in the UK

Why is it a Good Idea to Get Help from a Professional Tax Accountant for Capital Gains Tax in the UK?

Capital Gains Tax (CGT) in the UK is a complex area of taxation that can have significant financial implications. While it is possible to navigate CGT requirements independently, many individuals choose to seek the help of a professional tax accountant. Here's why engaging a tax professional can be beneficial.

Expert Knowledge of Tax Legislation

UK tax legislation is continuously evolving, making it challenging for laypeople to keep abreast of changes that could impact their financial situation. Professional tax accountants spend their working lives immersed in tax law. They have the in-depth knowledge needed to understand these complexities and can accurately interpret legislation as it relates to individual circumstances.


Understanding the intricacies of CGT and completing the necessary paperwork can be time-consuming. A tax accountant can take on these responsibilities, freeing up time for individuals to focus on their own areas of expertise, whether that be running a business or enjoying retirement.

Minimising Tax Liability

Tax accountants understand the various deductions, exemptions, and reliefs available that can minimise CGT liability. For example, they can guide clients on utilising allowances such as Private Residence Relief or Entrepreneurs' Relief, or advise on the implications of transferring assets between spouses or civil partners. They can also ensure that losses are correctly offset against gains, and help individuals plan their affairs to minimise future tax liabilities.

Avoiding Penalties

Mistakes in tax returns can lead to penalties from HM Revenue & Customs (HMRC). These can range from interest on unpaid taxes to substantial fines. A tax accountant can help ensure that all necessary paperwork is accurate and submitted on time, helping to avoid any unwelcome surprises.

Navigating Complex Situations

Certain circumstances can make CGT particularly complex. These might include the sale of a business, the disposal of inherited property, or the sale of shares in a company. In these situations, the guidance of a tax accountant can be invaluable. They can provide expert advice tailored to the individual's situation, ensuring that all tax implications are thoroughly considered.

Planning for the Future

Engaging a tax accountant is not just about dealing with the present; it's also about planning for the future. A good tax accountant will work with their clients to understand their long-term goals and aspirations and provide advice on how to structure their affairs to achieve these in the most tax-efficient way.

Peace of Mind

Perhaps most importantly, a tax accountant provides peace of mind. Knowing that a professional with expert knowledge is handling your affairs can alleviate stress and uncertainty. This can be particularly valuable in times of change, such as when selling a property or business, or when dealing with a significant inheritance.

While there is a cost involved in hiring a tax accountant, the potential savings, both in terms of money and time, often far outweigh the expense. A tax accountant can provide expert guidance, avoid penalties, help minimise tax liability, and provide valuable peace of mind. In the complex world of Capital Gains Tax, their expertise can be invaluable.
