Understanding How to Register as Self-Employed
If you start working for yourself in the UK, one of the first things you need to do is register as self-employed with HMRC.
Many people feel unsure about this process, especially when starting a freelance business or side hustle. The good news is that registering is usually straightforward once you understand the steps.
In this guide, we explain who needs to register, how to do it, and what happens after you register.
Who Needs to Register as Self-Employed?
You usually need to register if you:
Work for yourself
Sell goods or services regularly
Invoice clients
Earn money outside PAYE employment
Common examples include:
Freelancers
Consultants
Tradespeople
Online sellers
Creators or influencers
Side hustle businesses
If you earn more than £1,000 per year from self-employment, you normally need to register with HMRC.
When Do You Need to Register?
You must usually register for Self Assessment by 5 October after the end of the tax year in which you started trading.
For example:
Start business: June 2025
Tax year ends: April 2026
Registration deadline: October 2026
Registering early helps avoid missing deadlines.
How to Register as Self-Employed
To register, you normally need to:
Create or sign into your HMRC Government Gateway account
Register for Self Assessment
Provide details about your business
Wait for HMRC to confirm your registration
Once registered, HMRC will issue a Unique Taxpayer Reference (UTR).
What Happens After You Register?
After registering as self-employed, you will need to:
Keep records of income and expenses
Complete a Self Assessment tax return each year
Pay tax on your profits
Tax is usually paid after the end of the tax year.
You can learn more about this on our Self Assessment services page.
What Taxes Do Self-Employed People Pay?
Most self-employed people pay:
Income Tax on profits
National Insurance contributions
Remember: tax is calculated on profits, not total income.
Do You Need a Business Bank Account?
It’s not legally required for sole traders, but it’s strongly recommended.
Separating business and personal finances makes:
bookkeeping easier
tax returns simpler
financial tracking clearer
What Happens If You Don’t Register?
If you fail to register or submit a tax return when required, HMRC may charge:
Late filing penalties
Late payment interest
Additional fines
Registering early helps avoid unnecessary stress.
