Self Employment (SA103)

What is Form SA103?

This is a supplementary form used to report to HMRC any income received from business or self-employment. It is submitted alongside the main SA100 tax return and any other required forms.

It includes details of all income and allowable business expenses to show the profit or loss arising during the tax year.

What if I have multiple Self-Employment Businesses?

If you have more than one business, you will need to fill in a form for each business separately. You will also have to submit a separate form if you recently started or ceased a business or have changed the accounting date of your business.
