UK Freelancer Tax: Expenses You Can Claim
Claiming the right expenses can save UK freelancers hundreds or thousands in tax each year. Here is what HMRC allows — and what to avoid.
What Counts as an Allowable Expense?
HMRC allows sole traders and freelancers to deduct costs that are "wholly and exclusively" incurred for the purpose of their trade. That phrase — wholly and exclusively — is the key test. If an expense has a personal element, you can only deduct the business portion.
Claiming legitimate expenses reduces your taxable profit, which means you pay less Income Tax and National Insurance. Getting this right is one of the most impactful things you can do for your freelance finances.
Office and Working from Home Costs
If you work from home, you can claim a proportion of household costs including:
- Heating and electricity
- Broadband
- Rent (if you rent)
- Mortgage interest (but not capital repayment)
HMRC offers two methods. The simplified expenses method uses flat rates based on hours worked at home per month (£10/month for 25–50 hours, £18 for 51–100 hours, £26 for 101+ hours). Alternatively, you can calculate the actual proportion of your home used for work.
If you rent a dedicated office or co-working space, the full cost is deductible.
Equipment and Technology
Laptops, monitors, keyboards, phones, cameras, and specialist equipment used for your work are deductible. If you use a device partly personally, you can claim the business-use proportion.
Software subscriptions — design tools, project management apps, accounting software — are fully deductible as business costs.
Professional Fees and Subscriptions
Accountant fees, solicitor fees for business contracts, professional body memberships, and trade association subscriptions are all allowable. If you belong to a union or professional organisation relevant to your freelance work, that annual fee counts.
Training and Development
You can claim the cost of training that maintains or improves skills in your existing trade. A web developer paying for an advanced JavaScript course can deduct that. However, training to start an entirely new career generally cannot be claimed.
Travel and Subsistence
Travel to client sites and meetings is deductible. Keep records of:
- Mileage if you use your own car (45p per mile for the first 10,000 miles, then 25p)
- Train and bus fares
- Taxis to client meetings
- Parking costs
Your commute from home to a regular, fixed place of work is not deductible — but as a freelancer, most of your travel will qualify.
Meals while travelling are allowable if you are away from your normal place of work and the travel is for a qualifying business purpose. HMRC scrutinises meal claims, so be conservative.
Marketing and Advertising
Website hosting, domain names, advertising spend (Google Ads, social media), business cards, and any marketing materials are deductible business costs.
Bank Charges and Interest
Charges on a dedicated business bank account and interest on a business loan taken for your work are allowable. This is another reason to keep business and personal finances in separate accounts — it makes record-keeping straightforward.
What You Cannot Claim
- Client entertainment (entertaining clients at restaurants is specifically excluded by HMRC)
- Fines and penalties
- Clothing that could be worn outside work (even if you only wear it for work)
- The cost of preparing your self assessment tax return (though accountant fees for advising on tax are allowable)
Keeping Good Records
HMRC can ask to see records going back six years. Keep digital or paper copies of all receipts, invoices, and bank statements. Using accounting software or an app to photograph and categorise receipts as you go saves significant time at year end.
If you are not sure whether an expense qualifies, HMRC guidance at gov.uk is comprehensive, or speak to an accountant — their fee, of course, is deductible.
