Who needs to register as a freelancer?

If you work for yourself and earn more than the £1,000 trading allowance in a tax year, you must register as self-employed with HMRC. This applies whether freelancing is your main income or a side hustle.

Even if you earn less, it can still be worth registering if you want to build up National Insurance contributions.

When you must register

You must register by 5 October following the end of the tax year in which you started trading. Missing this deadline may lead to penalties.

How to register online (step-by-step)

1. Create a Government Gateway account if you don’t already have one.
2. Go to the HMRC website and choose “Register for Self Assessment and Class 2 National Insurance.”
3. Complete the online form with your personal details, business description, and start date.
4. Submit the form and wait for HMRC to process your registration.

Registration is free and usually takes a few minutes to complete.

What you’ll receive after registering

• Your Unique Taxpayer Reference (UTR) — usually posted within 10 working days.
• Confirmation of your Self-Assessment account.
• A request to pay Class 2 National Insurance if your profits exceed the threshold.

What to do after registering

• Start tracking your income and expenses straight away.
• Keep receipts, invoices, and records organised for your Self-Assessment return.
• Set aside money for tax — a fixed percentage of each payment is a good habit.
• Consider whether you may need to register for VAT later if your income grows.

Software like Keepr makes bookkeeping and expense tracking easy from day one.

FAQs

Can I freelance without registering?

No. If your profits exceed £1,000 in a tax year, you must register with HMRC. Failing to do so risks fines and interest charges.

Do I need a business name to register?

No. You can register under your own name as a sole trader. A business name is optional.

What if I already have PAYE income?

You still need to register if you also earn freelance income. You’ll declare both PAYE and freelance income on your Self-Assessment.
