1. When Should You Register as Self-Employed?

You are considered self-employed if you earn money by working for yourself or have set up a business to sell products or services. In most cases, the pay you received is untaxed. That essentially means it’s paid to you without any tax deducted so it’s up to you to declare it.

You are legally required to register as self-employed once the money you get paid (not your profit) goes over £1,000 during a tax year. Below this amount, you can avoid letting HMRC know about your business and paying any tax. This tax-free amount, otherwise called the trading income allowance, it isn’t always appropriate to use. Therefore, make sure you do your research before you claim it. 

Regardless of whether you are making a profit or even need to pay any tax, you’ll need to let HMRC know that you are self-employed. You need to do this by 5th October following the end of the tax year you first started your business. A tax year runs from 6 April to 5 April. So, for example, if you started your business on 1 January 2022, then you would need to let HMRC know by 5 October 2022.

Despite this deadline, I would advise you to register as self-employed as soon as possible because they prefer to know sooner rather than later. By doing this, you’ll also reduce the risk of receiving an automatic £100 penalty if you forget to do it.

2. Can You Run a Business Without Registering It?

Every sole trader needs to register for tax, whether they make a profit or not. That’s because HMRC wants to track what is happening with everyone’s earnings by using the process of self-assessment. So, you can start working for yourself and not worry about registering until your turnover exceeds £1,000. After that, you’ll need to register as self-employed.

If you are planning to operate through a Limited Company, you’ll need to register your business at Companies House. This is the first step you need to do before you can use the name and the letters LTD or Limited at the end of the name. You can also open a business bank account.

3. How Much Can You Earn as Self-Employed Without Paying Tax?

You can earn £1,000 tax-free by utilising the trading income allowance during the tax year. Once your income goes over £1,000, you can then earn up to £12,570 in profit for the tax year 2021/2022 without paying tax because of the personal allowance – the amount that everyone in the UK can earn tax-free. Even if you have no tax to pay, you must still register as self-employed and let HMRC know about your earnings. Once your profits go over the tax-free amount, you’ll start to pay income tax as follows:

  • 20% (basic rate) on profits between £12,570 to £50,270
  • 40% (higher rate) on profits between £50,271 to £150,000
  • 45% (additional rate) over £150,000

If you have other forms of income for example because you are employed and self-employed then you’ll pay income tax based on all your combined earnings – read this guide to find out more.

As a self-employed person, you’ll also pay National Insurance on your business profits, but again you won’t pay any if you earn up to the tax-free thresholds. Here are the National Insurance rates for the 2021/2022 tax year:

  • Class 2 National Insurance £3.05 per week on profits over £6,515 per year
  • Class 4 National Insurance. 9% on profits between £9,658 and £50,270 and 2% on profits thereafter

Despite not having to pay Class 2 National Insurance, some people choose to pay it voluntarily because it keeps their NI records up to date and protects their ability to claim state benefits like maternity allowance and the state pension.

Getting your head around when to register as self-employed doesn’t need to be overwhelming. Once you’re armed with the right knowledge, it can be a relatively easy to do.
