Self Assessment Tax Return Form Explained

What Is a Self Assessment Tax Return Form?

The Self Assessment tax return form is the document individuals in the UK use to declare income, gains, and certain expenses to HMRC. Unlike employees who are taxed through PAYE, those who are self-employed, company directors, landlords, or have other additional income must complete an HMRC Self Assessment form.

Common examples of people who need to file include:

  • Self-employed professionals and freelancers.
  • Business directors receiving dividends.
  • Landlords with rental income.
  • Individuals with income from abroad.
  • High earners above HMRC thresholds.

The process sounds simple, but in reality, the HM Revenue and Customs self assessment form can be complicated. One mistake may lead to HMRC queries, fines, or even investigations.

That’s why Audit Consulting Group provides professional assistance with Self Assessment registration forms, online forms, and submissions for the self-employed.

Find out which HMRC Self Assessment form you need based on your circumstances.

HMRC Self Assessment Forms – Which One Do You Need?

There are several different HMRC self assessment forms, depending on your situation:

  • HMRC self assessment tax form – the main form for declaring income.
  • Self assessment registration form – required when you first register for self-employment or as a director.
  • UK self assessment form – used by UK residents to declare worldwide income.
  • HM Revenue and Customs self certification form – for specific tax declarations like SSP (statutory sick pay) or additional relief claims.
  • Self assessment tax form online – the digital version most people now use.

We guide you through every step, ensuring you complete the right HMRC self assessment form for your circumstances.
