What Is The SA108 Form?

Updated: Nov 15, 2023

Understanding the SA108 Form in the UK for Tax Year 2023-2024

The SA108 form is a critical document for UK taxpayers, particularly for those dealing with capital gains. This form plays a pivotal role in the self-assessment tax process, allowing individuals to report any capital gains and the associated tax liabilities to HM Revenue & Customs (HMRC). As a taxpayer in the UK, understanding the intricacies of the SA108 form is essential for accurate and compliant tax filings.

What is the SA108 Form?

The SA108 form is designed to be used in conjunction with the main SA100 tax return form. Its primary purpose is to report capital gains or losses incurred during the tax year. Capital gains refer to the profit made from selling assets like property, shares, or even cryptocurrencies. For instance, if you've sold shares (excluding those from an ISA, which are tax-free), property, Bitcoin or other cryptocurrencies,

What Is The SA108 Form

When is the SA108 Form Required?

There are specific conditions under which you must complete the SA108 form. These include:

  1. Disposal of Assets: If you've disposed of assets worth more than £49,200 in the 2022/2023 tax year, or if your gains exceed the annual exempt amount, the SA108 form is necessary​​.

  2. Capital Gains Threshold: For the tax year 2022-2023, if your gains are less than £12,300, you are not required to fill out the SA108 form, as this amount falls under the annual exempt threshold​​.

Filling Out the SA108 Form

The SA108 form is a supplementary document to your main SA100 tax return. Its completion involves detailing the capital gains or losses from various types of assets. This detailed reporting is crucial for HMRC to assess the correct amount of tax owed or to confirm that your gains are within the exempt threshold.

Importance of the SA108 Form

The SA108 form is not just a bureaucratic requirement; it's a vital tool for financial transparency and tax compliance. By accurately reporting capital gains, you ensure that you're paying the correct amount of tax, thus avoiding potential penalties or legal issues. It's a way of maintaining a transparent and fair tax system, where each individual contributes proportionally to their financial gains.

Who Needs to File the SA108 Form?

The SA108 form is relevant for:

  • Individuals who have sold assets for a profit, such as property, shares, and other investments.

  • Those who have made a significant financial gain from the disposal of assets in the tax year.

  • Taxpayers who have exceeded the capital gains tax-free allowance.

Filling Out and Calculating Taxes with the SA108 Form

In the previous section, we delved into the basic understanding of the SA108 form in the UK for the tax year 2023-2024. Now, we'll focus on how to fill out the SA108 form and calculate the capital gains tax that may be owed.

Filling Out the SA108 Form

  1. Identifying Assets for Reporting: The SA108 form is used to report various types of assets. This includes shares (except those in an ISA), property, Bitcoin and other cryptocurrencies, art, jewellery, antiques, stamps, collectables, and any other assets that increased in value before being sold​​.

  2. Reporting Gifts: Capital gains tax is also applicable when gifting assets like property. All these are taxed at the same capital gains tax rate, except for property, which has a separate CGT rate​​.

  3. Reference Materials: It’s essential to download and read the “Capital gains summary notes” for the respective tax year from the HMRC website. This document explains each item on the SA108 form​​.

  4. Online vs Paper Submission: If you submit your self-assessment tax return online, you do not need to file the SA108 form separately. The deadline for paper tax returns is October 31st, whereas for online returns, it's January 31st​​.

  5. Accessing and Completing the Form:

    • Find the SA108 form on the HMRC website.

    • Select the appropriate tax year.

    • Download, print, and fill out the form.

    • Attach it to your SA100, the main tax return form.

    • Send it to HMRC​​.

Calculating Capital Gains Tax

Understanding CGT:

  • Capital Gains Tax (CGT) is charged when you sell or trade a property or asset for a profit. The amount of CGT to be paid is based on the profit gained, not the total sale amount. For example, if you sell a property for £200,000 that you originally purchased for £150,000, the CGT would be based on the £50,000 profit​​​​.

Tax Rates:

  • For basic taxpayers (income below £50,270), the CGT rate is 18% for property and 10% for other assets.

  • For higher or additional rate taxpayers (income above £50,270), the rate is 28% for property and 20% for other assets​​.

Calculation Method:

  • To calculate CGT, identify your original purchase price, any money spent on updates, and the sales price.

  • Subtract the original price and update costs from the sales price to find the profit.

  • Apply the relevant percentage based on your earnings bracket to determine the CGT owed​​.

CGT Allowance:

  • The CGT allowance for the 2022/23 tax year is £12,300 for individuals and £24,600 for married couples or civil partners. Profits below these amounts are not subject to CGT​​.

How to Fill Different Sections of the SA108 Form

3. Number of Disposals: Enter the total number of residential properties disposed of during the tax year.

4. Disposal Proceeds: State the total amount received from these disposals.

14. Number of Disposals: Enter the number of disposals of assets other than residential properties.

15. Disposal Proceeds: Total the proceeds from these disposals.

Each section of the SA108 form requires precise and accurate information about your disposals and gains.

Minimizing Capital Gains Tax Liability in the UK

Minimizing Capital Gains Tax Liability in the UK for Tax Year 2023-2024

In the previous sections, we covered the basics of the SA108 form and the process of calculating capital gains tax. This final part of our guide will focus on strategies to minimize your capital gains tax liability in the UK for the tax year 2023-2024.

1. Utilizing the CGT Allowance

The capital gains tax allowance, or the annual exempt amount, is a critical tool for minimizing CGT. For the tax year 2023-2024, you can use up to £6,000 of this allowance. This can be particularly effective if you can split a large gain across multiple tax years or use it strategically within your investment portfolio​​.

2. Transferring Assets to a Spouse or Civil Partner

Transferring assets to your spouse or civil partner can effectively double your CGT allowance, as each partner has their own allowance. This method is especially beneficial if your partner is in a lower tax bracket, as it could significantly reduce the overall CGT rate applied to the asset​​.

3. Offset Your Losses

If you have incurred losses on certain assets, these can be used to offset gains made elsewhere, effectively reducing your overall capital gains tax liability. Remember, you can carry forward losses from the past four years​​.

4. Deducting Costs

Certain costs associated with the acquisition and improvement of an asset can be deducted from your gains. This includes legal fees, estate agent's fees, and costs of improvements for properties; and auction charges or restoration costs for chattels like art and jewellery​​.

5. Increase Pension Contributions

Increasing your pension contributions can lower your income tax rate, which in turn could reduce the CGT rate you're subject to. This strategy is particularly effective if it shifts you from a higher to a basic tax rate​​.

6. Use Your ISA Allowance

Investments held in an ISA are sheltered from both income and capital gains tax. Maximizing your ISA allowance, currently £20,000 annually, is a smart way to protect a significant portion of your investment portfolio from taxes​​.

7. Bed and ISA Strategy

This involves selling assets held outside an ISA and immediately rebuying them within an ISA. Although CGT may apply if the gains exceed your allowance, it ensures that future gains on these investments are protected from tax​​.

8. Donations to Charity

Donating assets to charity can exempt you from paying CGT on those assets. This can be a beneficial strategy for those looking to support charitable causes while reducing tax liabilities​​.

9. Investing in Enterprise Investment Schemes

Investing in Enterprise Investment Schemes, which support small businesses, can offer tax breaks including CGT exemption if held for three years. This is more suitable for those with a high-risk tolerance and the financial ability to support small businesses​​.

10. Gift Holdover Relief

This applies when giving away business assets. The CGT is not payable by the donor at the time of the gift, although the recipient may have to pay it upon eventual disposal of the asset​​.

11. Exemptions for Certain Chattels

Certain chattels (personal possessions) are exempt from CGT, like those with a lifespan of less than 50 years and any items sold for less than £6,000. Understanding these exemptions can help you plan sales of personal possessions more effectively​​.

12. Caution with Asset Gifts

Be cautious when giving assets to anyone other than a spouse or civil partner, as this could result in a chargeable gain. The gain is calculated based on the market price minus the purchase price​​.

13. Professional Advice

Capital gains tax planning can be complex, especially with significant assets or changes in tax laws. Seeking advice from a qualified professional can be invaluable in navigating these complexities and ensuring tax-efficient strategies are in place​​.
