Claiming a tax deduction for a website and/or website support for UK businesses (2024 update)

Creating and maintaining a website is a vital aspect of modern business. Understanding how to claim tax deductions for these expenses can help you manage costs effectively. Here’s a comprehensive guide on how you can claim a tax deduction for website-related expenses in the UK.

Types of Website Expenses

Website expenses can generally be categorised into two types: capital expenditure and revenue expenditure. It’s important to understand the difference as it affects how you can claim tax relief.

Capital Expenditure

Capital expenditure includes the initial costs of creating or acquiring an asset that provides enduring benefits to your business. For websites, this includes:

  • Development Costs: Expenses incurred during the initial creation of the website, such as design and coding.
  • Domain Name: The purchase of a domain name for your business.
  • Hardware and Software: Costs related to hardware and software that enable the website’s functionality.

These costs are considered capital in nature and qualify for capital allowances (CAs). According to HMRC guidelines, these can be claimed as part of the Annual Investment Allowance (AIA), allowing you to deduct the full amount in the financial year they are incurred​​​​.

Revenue Expenditure

Revenue expenditure covers the day-to-day running costs of your business. For websites, this includes:

  • Maintenance and Updates: Regular updates to content, prices, and other elements of your website.
  • Minor Enhancements: Small improvements that do not extend the life of the website.

These costs are treated as revenue expenses and can be deducted from your profits like other business running costs (HMRC – Business Income Manual)​​​​.

Special Cases

Replacement Websites

If you are developing a replacement website, even one with the same domain name, these costs are treated as capital expenditure and qualify for capital allowances (Galley & Tindle)​​​​.

Advertising Websites

If your website primarily serves as an advertising tool, the costs are usually considered revenue expenses. This means you can deduct them from your profits in the same way as other advertising costs (The Friendly Accountants)​​​​.

Research and Planning

Initial research and planning costs before deciding to develop or redevelop a website are generally treated as tax-deductible revenue expenses (HMRC – Business Income Manual)​​​​.

Keeping Records

It’s crucial to keep detailed records of all website-related expenses. This helps ensure that costs are correctly categorised and the appropriate tax relief is claimed. Providing a detailed summary to your accountant will help them allocate costs correctly and maximise your deductions.


Understanding the tax implications of website costs can save your business money. By distinguishing between capital and revenue expenditures and keeping detailed records, you can ensure that you claim the maximum allowable deductions.

For more detailed guidance, refer to the HMRC Business Income Manual on the capital/revenue divide for website-related expenses.
