The SA109 Form

Expat & Non-Resident TaxFiling with Taxd
The SA109 is a supplementary page for the Self Assessment tax return that deals with residence, domicile, and the remittance basis. You'll need to complete it if your tax affairs have an international element.

The SA109 is used to provide HMRC with more detail about your international tax status. It is not a standalone form and must be filed alongside the main SA100 tax return.

When do I need to complete an SA109?

You will need to fill in an SA109 if, for the tax year, you are:

  • Claiming Split Year Treatment because you moved to or from the UK.
  • Declaring that you are not a UK resident for tax purposes.
  • Declaring that you are not UK domiciled.
  • Claiming the remittance basis of taxation.
  • Claiming personal allowances as a non-resident.

How Taxd helps

Navigating the SA109 can be complex. The Taxd platform simplifies this by asking a series of clear questions. Based on your answers about your time in the UK and your personal circumstances, our software will automatically populate the relevant boxes on the SA109 form for you.
