Tax return changes Directors should know about

From the 2025/26 tax year, HMRC is introducing additional reporting requirements for some individuals completing a self-assessment tax return.

The changes will be particularly relevant for directors of owner-managed limited companies, as well as self-employed individuals who start or stop trading during the tax year.

Many company directors will now be required to provide additional details within their self-assessment return, including:

• The company name and registration number
• Any dividends received from the company during the tax year
• Their percentage shareholding in the company

In addition, self-employed taxpayers who begin or cease trading during the year will need to report the relevant start or end date as part of their return.

While these changes do not alter how tax is calculated, they do increase the amount of information HMRC expects to receive. As a result, directors and business owners may wish to ensure their records are up to date throughout the year to make the reporting process smoother.
