What is Self Assessment?

Self Assessment is how you should declare income you've received to the government if you're a sole trader or a partner in a partnership business. It's how you declare income from the work you do.

You must submit your online Tax Return to HMRC by midnight on 31st January. If you send it after the deadline, you'll automatically be fined £100. This could increase depending on how long it takes you to file your tax return.
