What is an SA109?

While the form itself isn’t the most exciting thing to fill out, understanding what it is and why it matters can help make the self-assessment process a little less painful. Keep reading to get the full scoop on everything SA109 so you can tackle your tax return with confidence.

What Is the SA109 Tax Form?

The SA109 is a supplementary tax form for filing the Residence and remittance basis tax pages of your self-assessment.

As a landlord, self-employed individual or expat, you'll need to fill out the SA109 to disclose earnings, profits or losses from the previous tax year ending April 5th. The form covers income from employment, pensions, savings, investments and property. You'll report total earnings for each category and claim any tax relief or deductions you're entitled to.

Based on the information provided, HMRC will determine if you've paid the correct amount of tax for the year or if you're due a bill or rebate. For non-resident landlords and expats, the SA109 requires you to disclose UK rental and business income even if you live abroad.

The self-assessment tax return online deadline is January 31st following the end of the tax year. You must submit the SA109 and pay any tax due by this date to avoid potential penalties.

First, gather the necessary information, like your income statements, expenses, and other financial records from the tax year. You'll want everything handy so you can accurately report your earnings and claim any deductions or credits you're entitled to.

Then, go to HMRC website and download the SA109 form. You can print and fill it out manually. When the form is ready, you can also mail it to the address listed on the SA109.
