Your guide to self-assessment tax return

Your guide to self-assessment

If you find the thought of filing your self-assessment tax return form a daunting prospect, you’re certainly not alone!

It’s a common misconception that filling out your self assessment form is a complex process when in fact, if you are organised, prepared and understand what you need, the process can be really simple.

We’ve created a helpful guide to self-assessment, so that you have all the information you need to submit your self-assessment return.

First and foremost, who needs to submit a self-assessment?

If you meet the following criteria, you will need to submit a self-assessment:

  • Your self-employment income was more than £1,000
  • You need to pay Capital Gains Tax on profits from selling things like shares or a second home.
  • you’re a director of a company
  • You or your partner’s, income was over £50,000
  • you have income from abroad you need to pay tax on, or you live abroad but have an income in the UK.
  • Your taxable income was over £100,000
  • Your income from renting out property was more than £2,500
  • You earned more than £2,500 in untaxed income
  • Your income from savings or investments was £10,000 or more before tax.
  • You are a trustee of a trust or registered pension scheme
  • Your State Pension was more than your personal allowance and was your only source of income

Please note: You do not need to submit a  Self-Assessment tax return if you’re an employee who has paid tax through the Pay As You Earn system, however if you have earned over £100,000 you will need to pay.

How to register for a Self-Assessment tax return?
