New self assessment reporting requirements for close company directors from 6 April 2026

This specific Income Tax legislation will affect the majority of owner managed limited companies from 6 April 2026.

From 6 April 2026, HMRC have introduced additional reporting requirements for directors of close companies on their self assessment tax returns. 

If you are a director and shareholder of your own company, your personal tax return must now include the name and registered number of the company, the amount of dividend income you received from it during the year, and the highest percentage of share capital you held.

You must also confirm whether the company is defined as a 'close company'.

These requirements come from The Income Tax (Additional Information to be included in Returns) Regulations 2025, specifically regulations 4 and 5, which came into force on 6 April 2025 and apply to all tax returns from 2025/26 onwards.

HMRC are collecting more detailed information about the relationship between close companies and their directors, and this sits alongside the wider consultation on reporting payments to participators that I covered in a recent post.

If you are not sure how this affects your next tax return, or want to make sure your records are ready, get in touch.
