What is Self Assessment?

The UK self-assessment tax system requires individuals, self-employed workers, and business owners to report their income, capital gains, and other relevant information to Her Majesty's Revenue and Customs (HMRC) each year.

The tax year in the UK runs from April 6th to April 5th of the following year, and individuals are required to file their self-assessment tax returns accordingly. Many people procrastinate on this task until the deadline approaches, causing stress.

Who Should Submit a Self-Asssessment?

A Self Assessment Tax Return must be filed if any of the following criteria apply for the tax year:

  • Earned over £1,000 as a self-employed 'sole trader' (before any expenses)
  • Partner in a business partnership
  • Earned £100,000 or more
  • Received money from a rental property
  • Received tips and commission
  • Received foreign income
  • Earned income from savings, investments, and dividends
  • Received certain COVID-19 grant or support payments
  • Received child benefits if income exceeded £50,000 during the 2021/22 tax year.

Additional criteria apply to untaxed income, and it may be necessary to complete a tax return if you have received any of the following during the 2021/22 tax year:

  • Child benefits if the income was over £50,000
  • Some COVID-19 grant or support payments
  • Money from savings, investments, and dividends
  • Foreign Income
  • Tips and commission
  • Money from a rental property
