How to Report Freelance Income: A Complete Step-by-Step Guide for Freelancers
Freelancing in the UK has become more popular than ever. From graphic designers and writers to developers, consultants, and online sellers, millions of people now earn income outside traditional employment. While freelancing offers flexibility and independence, it also comes with one important responsibility: reporting your freelance income correctly to HMRC.
If you’re new to self-employment or simply want to make sure you’re doing things properly, this guide explains how to report freelance income in the UK, what forms you need, key deadlines, allowable expenses, and common mistakes to avoid.
What Counts as Freelance Income in the UK?
Freelance income includes any money you earn from self-employment, whether full-time or alongside a regular job. In the UK, HMRC considers you self-employed if you:
- Work for yourself rather than an employer
- Invoice clients for your services
- Decide how and when you work
- Take responsibility for profit or loss
Examples of freelance income include:
- Fees from clients or customers
- Online freelancing platform earnings
- Consulting or contract work
- Creative work (writing, design, photography)
- Digital services, tutoring, or coaching
Important: Even small amounts of freelance income must usually be reported.
Do You Need to Report Freelance Income to HMRC?
Yes. In most cases, you must report freelance income through Self Assessment if:
- You earned more than £1,000 from self-employment in a tax year
- You are registered as self-employed
- You receive untaxed income from freelance work
The £1,000 limit is known as the trading allowance. If your total freelance income is below this amount, you may not need to register, but you still should keep records.
Step 1: Register as Self-Employed
Before you can report freelance income, you must register with HMRC as self-employed.
When to Register
You must register by 5 October following the end of the tax year in which you started freelancing.
What Happens After Registration?
Once registered, HMRC will issue you:
- A Unique Taxpayer Reference (UTR)
- Access to the Self Assessment system
This allows you to file your tax return and pay any tax owed.
Step 2: Keep Accurate Records of Your Income
Good record-keeping is essential when reporting freelance income in the UK.
You should keep records of:
- Invoices sent to clients
- Bank statements showing payments received
- Cash payments
- Platform earnings summaries
- Dates and amounts of all income
HMRC requires you to keep records for at least 5 years after the submission deadline.
Using accounting software or spreadsheets can make this process much easier and reduce errors.
Step 3: Track Allowable Business Expenses
One major benefit of freelancing is the ability to deduct allowable expenses, which reduce your taxable profit.
Common Allowable Expenses
You can usually claim expenses that are wholly and exclusively for business purposes, such as:
- Office supplies and equipment
- Laptop, software, and subscriptions
- Phone and internet (business portion)
- Travel and transport for work
- Marketing and advertising
- Professional fees (accountant, legal advice)
- Home office costs
Simplified Expenses
HMRC allows simplified expenses for:
- Working from home
- Business mileage
- Personal use of business assets
These can save time if your business is small or straightforward.
Step 4: Complete Your Self Assessment Tax Return
The main way to report freelance income in the UK is through the Self Assessment tax return.
Which Forms Do You Need?
- SA100 – Main tax return
- SA103 – Self-employment (short or full version)
You’ll need to declare:
- Total freelance income
- Allowable business expenses
- Profit or loss
Your taxable profit is calculated as:
Freelance income – allowable expenses = taxable profit
Step 5: Submit Your Tax Return on Time
Missing deadlines can lead to penalties, so timing is crucial.
Key UK Tax Deadlines
- 5 April – End of the tax year
- 31 October – Paper tax return deadline
- 31 January – Online tax return deadline and tax payment due
If you submit online, you’ll also pay:
- Income Tax
- Class 2 National Insurance
- Class 4 National Insurance (if applicable)
Step 6: Pay Your Tax and National Insurance
Once you’ve reported your freelance income, you must pay any tax owed.
What You May Need to Pay
- Income Tax on your profits
- Class 2 National Insurance (flat weekly rate)
- Class 4 National Insurance (percentage of profits)
If your tax bill is high, HMRC may require Payments on Account, meaning advance payments for the next tax year.
Reporting Freelance Income Alongside Employment
Many people freelance alongside a PAYE job. In this case:
- Your employer handles tax on your salary
- You still report freelance income via Self Assessment
- Your total income determines your tax band
It’s important to budget carefully, as freelance income is not taxed automatically.
Common Mistakes to Avoid When Reporting Freelance Income
Avoid these common errors:
- Not registering as self-employed on time
- Forgetting to report small or cash payments
- Claiming non-allowable personal expenses
- Missing tax deadlines
- Failing to save money for tax bills
Mistakes can lead to penalties, interest charges, or HMRC investigations.
Do You Need an Accountant?
While it’s possible to report freelance income yourself, an accountant can:
- Ensure accuracy and compliance
- Maximise allowable deductions
- Save time and reduce stress
For complex situations or growing income, professional advice is often worth the cost.
Tips to Make Reporting Freelance Income Easier
- Open a separate business bank account
- Save 20–30% of income for tax
- Use accounting software
- Review HMRC guidance regularly
- File early to avoid last-minute stress
