Solder trader vs self-employed

Self-employed

If you don’t work as an employee for someone else and you earn income outside of the PAYE system, you would be classed as self-employed. The term self-employed doesn’t define the structure of a business, instead it indicates that the person works for themselves.

If you’re self-employed and own your business you would be classed as a sole trader. The term sole trader refers to the structure of your business.

When do I need to register as self-employed?

If you’re self-employed within the UK, you’re legally required to register as self-employed by 5 October, after the end of the tax year that you became self-employed.

For example, if you went self-employed with your business on 2 March 2024, you would need to register by 5 October 2024.

How do I register as self-employed?

  1. Start by visiting gov.uk to register and make your online HMRC account
  2. Once you’ve done this, you can then log into your account
  3. From there, select the ‘Add Tax’ option, and add ‘Self-Assessment’
  4. You’ll be presented with a list of options, select ‘Sole-Trader’
  5. You’ll then be prompted to start date for your self-employment
  6. Submit further info required, including your NI number
  7. Describe the work you do in basic terms, for example “Customer jewellery designer”
  8. Review the info you’ve shared to make sure it’s all correct and complete
  9. Submit your information

Once you’ve completed the above steps, you’ll receive your unique taxpayer reference (UTR) number by post. You’ll also be sent a separate letter with an activation code inside. These will be sent out you within 10 working days.

UTR stands for Unique Taxpayer Reference. This is a 10 digit code used by HMRC to identify you and your business. Your UTR is vital for managing any tax requirements and filings.

Does it cost to register?

Self-registering as self-employed on the HMRC website is free.

What to do if you’ve registered before?

It may be the case that you’ve registered for self-assessment before. However, if you’ve previously registered but you didn’t submit a tax return last year, you’ll need to register again. If you’ve registered and you’re still waiting on your UTR or to hear back from HRMC, you should contact HMRC directly.

When do I need to register for self-assessment?

Within the UK you can earn up to £1000 tax-free each tax year without being legally required to inform HMRC. This is due to the UK’s trading income allowance, and applies to small business owners, as well as anyone who earns income from a side hustle.

If you are self-employed and earn up to £1000 within the same tax year, you must register with HMRC for self-assessment.

Self-assessment is the system that HMRC uses to report your income and collect tax. To learn more, you can read our handy guide here.

This is not a real-life example but may help illustrate a specific scenario in which your small business does not meet the threshold for self-assessment:

Gemma is a small business owner, who sells homemade candles on Etsy and has made £875 within the year from selling her products. As this is under £1000, Gemma wouldn’t be legally required to register for self-assessment. Should Gemma’s business make over £1000 the following year, she would then be required to legally register for self-assessment.

Undeclared income

People may fail to report their income due to one or more of the following reasons:

They’re unsure of the correct process

They’re unaware of their legal obligation to inform HMRC

They’re unsure that they will be able to pay the tax amount

If you fit the criteria to be classed as self-employed and haven’t declared income earned that reaches the threshold, you should act to inform HMRC as soon as possible.

HMRC and undeclared income

HMRC investigates undeclared income a few different ways, including the use of technology that’s designed to analyse data for signs of tax evasion. On occasion, they may investigate individuals who have filed their tax credit or return applications incorrectly or inaccurately.

What to do after I’ve registered?

With the legal part ticked off, you can get back to building your new business and growing your customer base. And now that you’ve declared yourself as self-employed, you can enjoy the flexibility and freedom that comes with it.
