How to tell if you have to submit a UK tax return

Written by E4E Editor on 14 August 2018

While not all expats have to submit a tax return in the UK, a large proportion of British expats are required by the HMRC to complete a tax return and failure to do so could result in penalties and additional interest on late payments.

While the HMRC website has an online tool to assist people living in the UK determine whether they must submit a tax return in the UK, this was not created with expats, UK non-residents or non-British people living in the UK in mind.

6 key criteria used to determine whether you need to submit a tax return

  • Are you considered a tax resident of the UK?
    While the Statutory Residence Test will determine if you are a tax resident of the UK or not, if you spent more than 183 days in the UK you will most likely be deemed a tax resident of the UK and therefore required to declare all your worldwide income to the HMRC through a Self Assessment tax return.
  • Do/did you receive any untaxed income from sources in the UK (eg. rental income from a UK property)?
    You are not considered a tax resident of the UK, but you received income from the UK (for example you are a non-resident landlord and have UK rental income, pensions, dividends, UK based employment) this will be subject to UK tax laws and it is likely you will be required to submit a tax return.
  • Do you have income from abroad that you need to pay tax on?
    If you are a UK tax resident, you are normally required to pay UK tax on your worldwide income. Therefore if you received income from any non-UK source (for example a holiday rental, non-UK investments or non-UK employment) you are required to declare and pay tax on that income.
  • Are you a director of a UK registered company?
    If you are a director of a company registered in the UK, you will be required to submit a tax return – even if you are a non-resident of the UK.
  • Was your UK taxable income over £100,000?
  • Have you sold a UK property, shares or something else that you need to pay capital gains tax on?

If you answered yes to any of the above criteria, you will probably have to submit a tax return in the UK regardless of whether you are British or a foreign national. If you are unsure about the answer to any of the above questions, it is possible that you will be required to submit a tax return. However, in every case it is essential if you are unsure that you seek advice from a qualified tax consultant who both understands the rules around expat tax affairs but can also assist with the completion and submission of UK tax return.

It is worth noting that in the UK it is the taxpayer who is obliged to register for and submit a tax return, you cannot rely on HMRC to contact you and request a tax return is filed.

While submitting a tax return does not necessarily mean that you owe tax in the UK, it is important that a return is filed if you are obliged to complete one to avoid any late filing penalties and fines.

Submitting a tax return will ensure you claim any appropriate reliefs you are entitled to i.e. tax treaty relief if there is a double tax agreement in place, which will help you avoid double taxation.
