Self-Assessment is how individuals — including many company directors — report personal income to HMRC and pay any Income Tax due, separate from the company's own Corporation Tax.

1. Check Whether You Need to Register

Directors receiving dividends or other untaxed income often need to register for Self-Assessment.

2. Gather Your Income Records

This includes salary, dividends and any other personal income for the tax year.

3. File and Pay

The return is completed and filed online, with any Income Tax due paid by the relevant deadline.

This guide provides general information only. Not every director automatically needs to file — it depends on your personal income sources.
