How and When to Register Your Side Hustle with HMRC

Do you need to pay tax on a side hustle? It's a question that might have crossed your mind if you've started a side hustle or are thinking about starting one. 

In the UK, you can earn up to £12,570 per year before you need to pay income tax. However, the UK tax system, with its intricate regulations and exceptions, can be quite complex. Keep reading below; we're here to answer your questions.

WHEN DO YOU NEED TO REGISTER WITH HMRC FOR TAXES?

If you earn over £1,000 in sales revenue from a side hustle in a single tax year, you must register for self-assessment with HMRC. The £1,000 trading income allowance is separate from the £12,570 personal income tax allowance. This allowance only applies to individuals, not partnerships, and doesn't cover any costs you may have incurred.


The trading income allowance is particularly beneficial for those who have a part-time job or receive income from platforms such as Uber, Deliveroo, gardening services, blogging, selling on Amazon or eBay or pursuing hobby businesses. This means you can earn up to £1,000 without having to pay tax on this income. The £1,000 threshold applies to total earnings (sales income) rather than profits made.

key takeaway

If you earn less than £1,000 in sales revenue from your side hustle in a tax year, you're not required to pay tax on it.

HOW DO YOU REGISTER WITH HMRC FOR TAX PURPOSES?

How to Register for Self-Assessment with HMRC.


  1. Online Registration: The most straightforward way to register for self-assessment is through the HMRC website.
  2. Required Information: You'll generally need a National Insurance (NI) number to register. If you don't have one, you can seek guidance directly from HMRC.
  3. Alternative Methods: While the online method is recommended, you can also use form SA1 for registration. However, note that this form is usually not intended for self-employment income. Learn More
  4. Confirmation: If you're unsure about the registration process, it's a good idea to consult the HMRC help line for clarification.
  5. After Registration: Once you've successfully registered, HMRC will send you a ten-digit Unique Tax Reference (UTR) number. This process could take a few weeks.
  6. Setting up Government Gateway: After receiving your UTR, you can set up a Government Gateway account to view your tax records online and submit your annual self-assessment tax return.


By following these steps, you can navigate the self-assessment registration process with HMRC more efficiently.

WHAT IS THE TIME LIMIT FOR REGISTERING WITH HMRC?

You must register with HMRC by the 5th of October in the second tax year of your side hustle. Failing to meet this deadline may result in penalties, such as late filing fees and interest charges. The tax year starts on the 6th April and ends on the 5th April each year.


For example, if you began working on the 1st of February 2023, you must register with HMRC by the 5th of October 2023.

FAQs

  • Can I claim any expenses for my side hustle?

    Yes, but not if you use the £1,000 trading income allowance. You can either claim expenses or use the allowance, not both.

  • What happens if I have multiple side hustles?

    The £1,000 trading income allowance covers the total sales revenue from all your side hustles. If your combined earnings exceed this amount, you'll need to register with HMRC.
