What Expenses Can I Claim as a Freelancer? A Complete UK Guide

Understanding what expenses you can claim as a freelancer is essential for managing your business finances and reducing your tax bill. Many self-employed people either miss out on valuable tax relief or claim incorrectly, which can lead to issues with HM Revenue & Customs.


Whether you are a sole trader, contractor or self-employed individual, knowing how to claim allowable expenses ensures you only pay income tax on your true taxable profit. This guide explains allowable business expenses, what you can and cannot claim, and how to approach your self-assessment tax return with confidence.

What are allowable expenses?

Allowable expenses are business expenses that are wholly and exclusively related to your business purposes. This means the cost must be directly related to your work and not for personal use or mixed business and personal reasons unless appropriately apportioned.


HMRC provides clear guidance on what qualifies as allowable business expenses in its overview of self-employed expenses, which outlines how to deduct expenses correctly when calculating taxable profit.


By claiming allowable business expenses, freelancers reduce the amount of income tax they pay, ensuring they are not taxed on money spent running their business.

How claiming expenses affects your tax bill

When you claim expenses, you deduct them from your total business income. The remaining amount is your taxable profit, which determines how much tax you pay.


For example, if your freelance income is £40,000 and your allowable expenses total £10,000, you only pay tax on £30,000. This can significantly reduce your tax bill and improve cash flow.


If your allowable expenses are below £1,000, you may choose to use the trading allowance instead. This is explained in HMRC’s guidance on the trading allowance.

Common business expenses freelancers can claim

Freelancer expenses cover a wide range of costs, provided they are related to your business.


Office costs are one of the most common categories. This includes office equipment, computer software, stationery and broadband costs. If you work from home, you may also claim a portion of rent or mortgage interest, council tax and utilities based on business use.


Travel expenses are also claimable. This includes business travel such as train fares, taxi fares, vehicle hire charges and business miles if using your own car. HMRC allows either actual costs or simplified expenses using a flat rate, depending on your preference. Details on mileage rates are set out in the government’s guidance on simplified expenses.


Car expenses must reflect business use only. Personal use must be excluded to ensure compliance.


Professional fees and business insurance premiums are also allowable. This includes professional indemnity insurance, membership of a professional organisation and legal costs related to your business.


You can also claim financial costs such as bank charges, interest on business loans and some credit card charges where they relate directly to business activities.

Travel, accommodation and subsistence

Freelancers often incur costs when working away from their usual place of business. Overnight business trips allow you to claim reasonable costs such as hotel room costs, meals and travel expenses.


These must be strictly for business purposes. If a trip includes both business and personal reasons, only the business-related portion can be claimed.


Business trips, including meetings with clients or attending industry events, are generally allowable provided they are necessary for your work.

Capital allowances and larger purchases

Capital expenses, such as purchasing office equipment, machinery or vehicles, are treated differently from everyday business expenses. Instead of deducting the full cost immediately, you may need to claim capital allowances.


HMRC explains how to claim capital allowances for items such as computers, tools and other assets used in your business.


This approach ensures that larger investments are accounted for correctly over time, rather than distorting your taxable profit in a single tax year.

Expenses you cannot claim

Not all costs are tax-deductible. HMRC is clear that expenses must be wholly for business purposes.


You cannot claim clothing expenses for everyday wear, including a standard business suit, as these are considered suitable for personal use. Similarly, entertaining clients is not an allowable expense for tax purposes, even if it is part of building relationships.


Costs that relate to personal use, such as private mobile phone usage or non-business travel, must be excluded or apportioned accurately.



Understanding what you cannot claim is just as important as knowing what you can, as incorrect claims can lead to penalties.

Simplified expenses vs actual costs

Freelancers can choose between simplified expenses and actual costs when calculating certain expenses.


Simplified expenses allow you to claim a flat rate for costs such as working from home or using your vehicle for business miles. This approach reduces administrative work and is often suitable for smaller businesses.


Actual costs involve calculating the precise business proportion of each expense, such as splitting broadband costs or rent based on business use.



The choice between simplified expenses and traditional accounting depends on your circumstances and how detailed your record-keeping is.

Record keeping and compliance

Accurate record keeping is essential when claiming expenses. You should retain receipts, invoices and bank statements to support your claims.


HMRC requires freelancers to keep records that demonstrate how expenses relate to business purposes. This includes tracking business calls, maintaining details of travel expenses and documenting any split between business and personal use.


Good record-keeping not only ensures compliance but also makes completing your self-assessment tax return far more straightforward.

How an accountant can help freelancers

Managing freelancer expenses can quickly become complex, particularly when dealing with capital allowances, mixed-use costs and changing tax rules.


An experienced accountant helps you identify allowable expenses, ensure compliance and maximise tax efficiency. This includes advising on whether to use simplified expenses or actual costs, calculating how much tax you owe and ensuring your assessment tax return is accurate.

HMRC and Companies House have confirmed that from 1 April, all businesses must use compliant, commercial software to file their company’s tax returns. As of 31 March, the free joint online service, commonly known as the CATO portal, from these two Government bodies has been removed and you must now use software to file company tax returns to HMRC. For the time being, you will still be able to file annual accounts at Companies House using third-party software, WebFiling services or paper filing. The decision has been made to end this service as it is “outdated and no longer aligns with modern digital standards”, according to Companies House. This change is in line with the introduction of the Economic Crime and Corporate Transparency Act, which implemented “enhanced corporation tax requirements and changes to UK company law.” It also follows on from a major IT security breach at Companies House, identified in March 2026, that exposed the WebFiling system and allowed some users to potentially access and amend the details of other companies. Although the breach has now been resolved and security strengthened, it has raised concerns about the reliability of GOV.UK One Login service.  Can you still amend previous returns using the free service? HMRC and Companies House have confirmed that now that the free filing service has closed, company directors will have to use commercial tax software if they need to make changes to a previously submitted Corporation Tax return or refile a rejected return. From now onwards, any previously filed financial information will no longer be available in the system, as it has not been retained and will need to be entered again. HMRC has said that, for amendments, it will also be acceptable to send a paper return to the Corporation Tax Services office. If you have previously filed financial accounts with Companies House and you want to make changes or corrections, this will also need to be done via commercial software or by sending paper accounts to Companies House via post. Are there any exceptions to this new rule? Companies can file a paper Corporation Tax return only in limited circumstances, such as if they wish to submit it in Welsh or can demonstrate a valid, reasonable excuse to HMRC. Otherwise, returns must be filed online using commercial software. If you are affected by this change and need help choosing and utilising commercial software to complete your Corporation Tax return, please speak to our team.

Capital allowances continue to provide an effective method for businesses to reduce their tax bills, by providing incentives for investment in eligible expenditure – typically plant and machinery. Historically, these reliefs have been subject to change and the 2026/27 tax year is no different, as the Government moves to alter two key reliefs – Writing Down Allowance (WDA) and a new First-Year Allowance (FYA).  Reduction of the Writing Down Allowance The WDA will be reduced from 18 per cent to 14 per cent on the main pool of qualifying plant and machinery assets. This change has been introduced on two different dates, starting with companies subject to Corporation Tax on 1 April and followed shortly thereafter by those subject to Income Tax, such as sole traders and partnerships, from 6 April. Businesses with large brought forward main pool expenditures are expected to lose the most from the reduction in the main rate of WDA. In the long-term, the change may also reduce incentives for investment in second-hand assets and cars, which benefited under the previous rules. The new First-Year Allowance To offset some of the impact of the reduction in WDA, a new 40 per cent FYA on main rate expenditure, primarily still covering plant and machinery, will now be available. This new FYA is intended to encourage investment in areas where other FYAs don’t allow, in particular, assets bought by unincorporated businesses and leases. Sole traders and partnerships will, for the first time, be able to get additional support at the point of investment, which means that more businesses will be able to reduce their tax bill in the same year as their investment. This is expected to give a quick cashflow boost to those affected and provide additional support for future investments. However, it is important to note that this FYA does not support investment in second-hand assets, cars or leased assets in other countries. Finally, the Government has also confirmed that small business owners will continue to benefit from tax relief on electric vehicles, as the 100 per cent FYA for zero-emission vehicles and charge points has been extended until 31 March 2027 for Corporation Tax and 5 April 2027 for Income Tax. This gives businesses greater certainty when planning ahead, while also providing a strong financial incentive to invest by reducing tax bills upfront. Want to make more of capital allowances? If you think you may be eligible for capital allowances, either due to the changes outlined in this article or more generally, then it is important that you claim the tax relief available to you.
