What is a Self-Assessment Tax Return?

A self-assessment tax return, often referred to as the SA100, is how you report untaxed income, such as earnings from self-employment, rental properties, dividends, and capital gains, to HMRC. If your income isn’t taxed at source, you’ll need to file an SA100 form online or by paper.

Who Needs to File an SA100 Tax Return?

You need to complete and submit a tax return if:

• You’re self-employed or a freelancer.
• You’re a company director.
• You earn over £100,000 annually.
• You have untaxed income, such as rental income or savings.
• You’ve paid capital gains tax or the High-Income Child Benefit Charge.
