What’s the Difference Between SA100 & SA302 Forms?

The SA100 needs to be completed by 31st October if using the paper method or 31st January if you are using HMRC online services.
It is commonly called either the self assessment or the tax return and both of these can also be referred to as the SA100 form. This is for the self employed to declare their earnings for the tax year and to pay any tax they owe. It is a substantial document with many pages to it and should not be used instead of an SA302.
The SA302 form is a succinct summary of your earnings and tax for the year. This is an official document issued by HMRC after the submission of your tax return. It is the best document to show anyone that may need this information. You cannot have one form without the other.
