What is an SA109 form?

The SA109 is a supplementary tax form for filing the residence and remittance basis tax pages of your Self Assessment.

Who needs to file SA109 form?

You will need to fill out an SA109 if you are:

  • a non-UK resident
  • not ordinarily resident or not domiciled in the UK
  • classed as a dual resident in the UK and another country

What information do you need to provide?

The SA109 form is for people who don’t live in the UK but earn money there. They need to fill in what kind of money they made, how much, and any tax breaks they can get.

The form also asks where they live and how long they were in the UK during the tax year.
