File Your SA800 Partnership Tax Return with GoSimpleTax
Running a business as a partnership? You’ll need to file an SA800 Partnership Tax Return with HMRC every year—alongside your own personal tax return (SA100). GoSimpleTax makes the process simple, stress-free, and compliant with HMRC’s requirements.
What is an SA800?
The SA800 is the official tax return form for UK business partnerships. It’s used to report the partnership’s total income, expenses, and profit or loss to HMRC. Think of it as the tax return for the business as a whole, not the individual partners.
Who Needs to File an SA800?
If you run a business as a partnership in the UK, you must file an SA800 every year, regardless of how much profit you make. The SA800 is filed by the partnership itself – and each partner must also file an individual tax return (the SA104) to report their share of the profits.
