What Does Being a Freelancer Mean for Your Taxes?
In the UK, freelancers are generally considered self-employed. This means youâre effectively running your own business, providing services to clients, and responsible for paying your own tax and National Insurance.
The important bit? You need to:
- Register as self-employed with HMRC
- Maintain precise and unambiguous records of your income and outlays.
- Submit a Self Assessment tax return every year
Step 1: Registering as Self-Employed
Youâve got to let HMRC know youâre self-employed within three months of starting your freelance work â missing this can lead to fines. The good news is that registering online is simple and quick. Once done, youâll get a Unique Taxpayer Reference (UTR) that youâll need for tax returns.
Step 2: What Taxes Do Freelancers Pay?
Income Tax
You pay income tax on your profits â thatâs your income after business expenses. Hereâs how the 2025 UK income tax bands break down:
- Up to ÂŁ13,000: Tax-free personal allowance
- ÂŁ13,001 to ÂŁ50,270: Basic rate at 20%
- ÂŁ50,271 to ÂŁ125,140: Higher rate at 40%
- Above ÂŁ125,140: Additional rate at 45%
National Insurance Contributions (NICs)
Freelancers pay two types of NICs:
- Class 2 NICs: ÂŁ3.45 a week if profits exceed ÂŁ12,570
- Class 4 NICs: 9% on profits between ÂŁ12,570 and ÂŁ50,270, plus 2% on profits above that
Step 3: Keep Your Records Spot On
Keeping good records is absolutely essential. Make sure to save:
- Invoices and payments from clients
- Receipts for any business costs
- Bank statements linked to your work
- Travel and mileage logs if applicable
Many freelancers find it easier to use accounting software like QuickBooks or Xero to stay organised.
Step 4: Which Expenses Can You Claim?
Claiming allowable expenses reduces your taxable profits, which means paying less tax. Typical expenses you can claim include:
- Office costs like rent, bills, and internet
- Equipment and software subscriptions
- Travel costs for work trips
- Advertising and marketing expenses
- Professional fees and relevant training courses
Just keep in mind that spending must be “wholly and exclusively” for your company.
Step 5: Filing Your Tax Return
Your Self Assessment tax return needs to be submitted by 31 January after the tax year ends (which is 5 April). Filing on time avoids penalties and lets you claim any tax reliefs youâre entitled to.
Whatâs New for Freelancers in 2025?
- Personal allowance increased to ÂŁ13,000
- Tighter rules around IR35 for freelancers using limited companies
- Simplified digital reporting to ease paperwork
- New incentives for eco-friendly and sustainable business expenses
Common Freelancer Tax Mistakes to Avoid
- Delaying registration â register promptly to avoid fines
- Mixing personal and business finances â keep everything separate
- Forgetting to set aside money for tax â ideally, save 25-30% of your earnings
- Missing deadlines for filing and payments
- Failing to notify HMRC of any modifications to your company
