Retain all relevant records

It's important to retain all relevant records for the period you're working outside of the UK. These include:

  • Travel - boarding cards, booking receipts, confirmation emails
  • Overseas work - meeting agendas, itineraries, screenshots of emails sent for days spent working in and outside the UK
  • Investments - statements or certificates relating to any UK investment income for the tax year.

These records may be required for accurate completion of your UK tax return and will be needed if HMRC decide to audit your tax return.

These records should be retained for at least 12 months after the date your UK tax return is filed.

By 5 October

Once the UK tax year has ended, and before 5 October, you will need to do the following:

  • Assess whether you need to file a tax return by completing HMRC’s online tool
  • If you need to file a tax return, register for Self-Assessment by completing the SA1 ‘Registering for Self Assessment form, if you don’t already have a UTR. This registers you with HMRC and a 10 digit Unique Taxpayer Reference (UTR) will be issued by HMRC to allow you to file online.

Click here to complete the form - this can be completed online via Government Gateway, or you can complete and print a copy of the form. Click here for guidance on filling out the SA1 form.

If completing the postal form, return the original signed copy by post to HMRC on the address marked on the form.

There are penalties for late filing of your tax return so it's very important you remember these dates.

Tax return liability or refund

You will have paid taxes via PAYE but when you file your tax return, there may be an overpayment or underpayment showing.

Overpayment

This should be paid to you within a few weeks of filing your tax return. HMRC will usually send the refund by cheque but you can choose to receive the refund by bank transfer if you select this method and you provide your bank details on the tax return form. HMRC will only make bank transfers to bank accounts in the UK, Jersey, Guernsey or the Isle of Man.

Underpayment

This should be paid to HMRC by 31 January after the end of the tax year. If there's a large liability, advance payments on account may able be due for the following year. If payments on account are required, HMRC should provide instructions on amounts due and deadlines for payment.
