Companies House: software-only accounts from 1 April 2028, and identity verification

Two big changes reach every UK company director. Identity verification is already a legal duty. Software-only accounts filing starts on 1 April 2028. This guide explains both in plain words and gives you a short plan.

This is general information. It is not advice on your own company's situation.

Part 1: accounts by software only from 1 April 2028

Companies House says: from 1 April 2028, all companies must file their accounts using commercial software. This applies whether you file your own accounts or use an accountant. There will be no transition period, and revised accounts are included. (gov.uk: using software to file your company's information)

After that date, the Companies House web and paper services close for accounts. You can still file other statutory information through the web service. Accounts must be filed in iXBRL format. (gov.uk news, 9 June 2026)

Why 2028 and not 2027

The change was first planned for April 2027. On 9 June 2026 the government moved it to April 2028, so that every company has one full accounting year plus 9 months, 21 months in all, to get ready. (gov.uk news)

What else changes for small companies

The government's Changes to UK company law site lists these accounts changes for April 2028. (changestoukcompanylaw.campaign.gov.uk)

When does this hit you?

Your accounts are due at Companies House 9 months after your financial year ends. (gov.uk) Any accounts filed on or after 1 April 2028 must go through software. For example, a company with a year end of 31 July 2027 has accounts due by 30 April 2028, so if it files after 31 March 2028 it will need software. If you are late with any older accounts, the same rule applies to them.

Part 2: identity verification

Identity verification became a legal requirement from 18 November 2025. It covers all directors and people with significant control (PSCs). Companies House calls 18 November 2025 a starting point, not a deadline, and there is a 12 month transition period to get everyone verified by their due dates.

When you need to do it

From gov.uk: when you need to verify your identity:

How to verify

You have three routes. (gov.uk)

Expired passports cannot be used. A DVLA driving licence must have expired within the last 90 days.

When you are verified you get a personal code. Keep it safe, because you will need it for the filings in the table above.
