Being self-employed or working as a freelancer means you are responsible for reporting your income and paying tax on your profits.
One of the best ways to reduce your tax bill legally is to claim all allowable business expenses you are entitled to.
Allowable expenses reduce your taxable profit, meaning you only pay tax on the income that remains after eligible business costs have been deducted.
This guide explains the most common expenses freelancers can claim in the UK and the mistakes to avoid.
What Are Allowable Expenses?
Allowable expenses are costs that are incurred wholly and exclusively for the purpose of running your business.
If an expense is partly personal and partly business-related, normally only the business portion can be claimed.
For example:
- A laptop used entirely for work may be fully allowable.
- A mobile phone used for both personal and business use may only allow the business proportion.
Keeping accurate records throughout the year helps ensure you claim correctly.
Common Allowable Expenses for Freelancers
- Home Office Expenses
Many freelancers work from home and may be able to claim costs associated with running their business.
You can usually choose between:
Simplified Expenses
A flat-rate method based on the number of hours you work from home.
Actual Costs
A proportion of household expenses, such as:
- Electricity
- Gas
- Heating
- Internet costs
- Council Tax
The amount claimed should reflect business use only.
- Phone and Internet Costs
Business-related communication costs may be allowable.
Examples include:
- Business phone contracts
- Internet services used for work
- Mobile data costs
If a service is used personally as well, only the business element should normally be claimed.
- Travel and Mileage Expenses
Freelancers can often claim business travel costs.
Examples include:
- Public transport fares
- Business mileage
- Parking costs incurred for business reasons
- Accommodation for business trips
However, normal journeys between your home and a permanent workplace are generally treated as commuting and are not usually allowable.
- Equipment and Software
Many freelancers rely on digital tools and equipment to operate their businesses.
Potentially allowable costs include:
- Computers and laptops
- Printers
- Business equipment
- Accounting software
- Design software
- Cloud storage subscriptions
- Online tools used for work
Some larger equipment purchases may be treated differently for tax purposes and could qualify for capital allowances.
- Marketing and Advertising Costs
Promoting your freelance business is an important investment.
Allowable marketing expenses may include:
- Website costs
- Domain registration
- Online advertising
- Social media advertising
- Graphic design services
- Business stationery
- Professional Fees and Insurance
You may be able to claim costs such as:
- Accountant fees
- Tax adviser fees
- Business insurance
- Professional indemnity insurance
- Legal fees related to your business
- Bank Charges and Payment Fees
If you use financial services for your business, you may be able to claim:
- Business bank charges
- Payment processing fees
- Transaction fees
Common Tax Mistakes Freelancers Make
Not Tracking Expenses throughout the Year
Many freelancers lose money by failing to record small but legitimate business costs.
Keeping records regularly makes tax filing easier and reduces the chance of missing allowable expenses.
Claiming Personal Expenses
A common mistake is claiming costs that are not related to business activities.
Examples include:
- Personal shopping
- Private travel
- Personal subscriptions
Missing Mileage Claims
Freelancers who travel for business often forget to record mileage.
Keep a record of:
- Date of journey
- Destination
- Business purpose
- Miles travelled
Not Keeping Receipts and Records
HMRC requires taxpayers to keep sufficient records to support their tax return.
Good record keeping helps you:
- Complete your return accurately.
- Support expense claims.
- Respond to HMRC questions.
