Completing a self-assessment (SA) tax return is one of the key tasks in the self-employed calendar.

Issued by HM Revenue & Customs (HMRC) they are issued to people who are self-employed whether this is on their own or in a partnership and to company directors.

Anyone who receives a self-assessment tax return from HMRC is legally obliged to complete and submit it, either by post or by filing a tax return online.

We’ve teamed up with the Federation of Small Businesses (FSB) to produce a series of helpful guides whether you are new to self-employment or have been for a while and with the deadline for submitting your SA just around the corner, we looked at what’s involved.
