A different self-assessment tax return for business partners

Unincorporated general business partnerships themselves aren’t actually taxed, but you will need to file an SA800 tax return to declare any profits your partnership makes in the tax year and tell HMRC how it’ll be split.

You and each self-employed partner will then need to complete a SA100 personal tax return via self-assessment before the deadline. There’s an extra page (SA104) for us to complete on your behalf, which sets out the partners’ ownership share and helps work out how much tax you owe individually. We’ll work with you to make sure it’s done and dusted in plenty of time.
