How to Work Out Capital Gains Tax on Property: A Comprehensive Guide

Figuring out Capital Gains Tax (CGT) on property can feel like navigating a labyrinth. The calculation involves understanding several factors, from purchase price to allowable expenses and available reliefs. Simply put, to work out CGT on property, you need to determine the capital gain (the difference between the selling price and the purchase price, adjusted for allowable expenses) and then apply the appropriate CGT rate to that gain. Let’s break this down into manageable steps.

Understanding the Basics of Capital Gains Tax on Property

Before diving into the nitty-gritty, it’s crucial to grasp the fundamental concept. Capital Gains Tax is levied on the profit you make when you sell or dispose of an asset that has increased in value. This applies to various assets, including shares, investments, and, of course, property. However, not all property disposals trigger CGT. Your primary residence typically qualifies for Principal Private Residence (PPR) relief, meaning any gain made on its sale is usually exempt from CGT. The complexities arise when the property is not your PPR, such as a second home, a buy-to-let property, or land.

Step-by-Step Calculation of Capital Gains Tax

Here’s a detailed breakdown of how to calculate CGT on property:

1. Determine the Disposal Value: This is the amount you receive for selling the property. It’s usually the sale price, but you need to factor in any related costs.

2. Calculate the Acquisition Cost: This is the original purchase price of the property, plus any associated costs like stamp duty, legal fees, and surveyor fees incurred during the purchase.

3. Add Allowable Expenses: This is where things get interesting. You can deduct certain expenses from the capital gain to reduce your tax liability. Allowable expenses include:

   • Estate agent fees paid for selling the property.
   • Legal fees paid for buying and selling the property.
   • Costs of improvements that enhanced the property’s value (e.g., an extension or a new kitchen). Note that routine maintenance (like painting and decorating) typically isn’t deductible.

4. Calculate the Capital Gain: Subtract the acquisition cost and allowable expenses from the disposal value. The formula is:

   Capital Gain = Disposal Value – Acquisition Cost – Allowable Expenses

5. Deduct Your Annual CGT Allowance: Everyone gets an annual CGT allowance (currently £6,000 for the 2024/25 tax year, but these figures can change). You can deduct this allowance from your capital gain to reduce the taxable amount.

6. Apply the Appropriate CGT Rate: The CGT rate you pay depends on your income tax band and the type of asset. For property, the rates are typically higher than for other assets. As of 2024/25, the CGT rates on property are:

   • 18% for basic rate taxpayers.
   • 24% for higher rate and additional rate taxpayers.

7. Report and Pay the CGT: You must report the capital gain to HMRC (Her Majesty’s Revenue and Customs). The deadline for reporting and paying CGT depends on how you dispose of the property. For residential property, you must report and pay CGT within 60 days of the completion date of the sale. This is done online through HMRC’s “Report Capital Gains Tax on UK Property” service.

Example Calculation

Let’s illustrate with an example:

• Sale Price (Disposal Value): £350,000
• Purchase Price (Acquisition Cost): £200,000
• Stamp Duty and Legal Fees on Purchase: £6,000
• Estate Agent and Legal Fees on Sale: £4,000
• Cost of Improvements (New Kitchen): £10,000

Calculation:

1. Capital Gain Before Allowances: £350,000 – £200,000 = £150,000
2. Total Allowable Expenses: £6,000 + £4,000 + £10,000 = £20,000
3. Capital Gain After Expenses: £150,000 – £20,000 = £130,000
4. Deduct Annual CGT Allowance (Assuming £6,000): £130,000 – £6,000 = £124,000
5. Taxable Capital Gain: £124,000

If you’re a higher rate taxpayer (earning above £50,270 per year), you’d pay 24% CGT on £124,000.

CGT Due: £124,000 x 0.24 = £29,760

Frequently Asked Questions (FAQs)

Here are some frequently asked questions about Capital Gains Tax on property:

FAQ 1: What is Principal Private Residence (PPR) Relief?

PPR relief exempts you from paying Capital Gains Tax on the sale of your main home. To qualify, the property must have been your primary residence for the entire period of ownership. However, there are exceptions and rules regarding periods of absence, letting, and the size of the grounds.

FAQ 2: What happens if I lived in the property as my primary residence for only part of the time I owned it?

You can still claim PPR relief for the period you lived in the property as your primary residence. The gain is apportioned, and only the portion relating to the time the property was not your primary residence is subject to CGT.

FAQ 3: Can I deduct the cost of improvements made to the property?

Yes, but only improvements that enhance the value of the property are deductible. Routine maintenance, such as painting, decorating, or repairing existing features, is not deductible. Improvements like adding an extension, a new kitchen, or a conservatory are generally allowable.

FAQ 4: How does letting relief work?

Letting relief can reduce your CGT liability if you rented out a property that was previously your primary residence. The relief is the lower of:

• The amount of PPR relief you’ve already claimed.
• £40,000.
• The amount of the chargeable gain arising from the letting.

This relief can significantly reduce the CGT payable when you sell a property that has been both a primary residence and a rental property.

FAQ 5: What if I inherit a property?

When you inherit a property, you are treated as having acquired it at its market value on the date of death of the deceased. This becomes your acquisition cost for CGT purposes. If you later sell the property for more than that value, you’ll be liable for CGT on the gain.

FAQ 6: What if I transfer a property to my spouse or civil partner?

Transfers of assets between spouses or civil partners are generally exempt from CGT. The recipient spouse or civil partner takes over the original acquisition cost and date.

FAQ 7: What happens if I sell a property at a loss?

If you sell a property at a loss, you can offset the loss against other capital gains you have made in the same tax year. If the loss exceeds your gains for the year, you can carry the remaining loss forward to offset against future capital gains.

FAQ 8: Do I need to keep records of my property-related expenses?

Absolutely. Maintaining detailed records of all purchase documents, invoices for improvements, estate agent fees, and legal costs is crucial. These records will support your CGT calculation and are essential if HMRC decides to investigate your tax return.

FAQ 9: What if I develop land and then sell it?

If you develop land and then sell it, the CGT calculation can be more complex. You may be able to deduct the costs of development, but the overall gain could be treated as income if HMRC considers the activity to be trading. Seeking professional advice in this situation is highly recommended.

FAQ 10: Are there any other reliefs available besides PPR relief and letting relief?

Yes, there are other reliefs available, such as business asset disposal relief (formerly entrepreneurs’ relief), which can reduce the CGT rate on the disposal of certain business assets. However, this relief is unlikely to apply to most property disposals.

FAQ 11: How do I report Capital Gains Tax to HMRC?

For residential property sales, you must report the gain within 60 days of the completion date via HMRC’s online portal. You will need to create an account and follow the instructions to report the gain and pay the tax. For other asset disposals, you report the gain on your Self Assessment tax return.

FAQ 12: When is the payment deadline for Capital Gains Tax?

For residential property sales, CGT is due within 60 days of completion. For other asset disposals reported on your Self Assessment tax return, the payment deadline is usually January 31st following the tax year in which the gain was made.
