Do not wait until 2028 to organise the companies you will have to file by software.
Companies House has announced that annual accounts filing will move to commercial software from 1 April 2028. Build the portfolio, deadline and filing workflow before the transition date.
Filing Deadlines
Accounts and confirmation statement dates across the portfolio.

The 2028 change is operational, not just technical.
Know the portfolio
Identify every company you expect to manage before the mandatory software-filing date arrives.
Know the deadlines
Maintain filing dates and first-accounts exceptions rather than discovering them during migration.
Know the authority
Decide who can file and how company authentication and identity-verification information will be controlled.
Know the filing record
Retain acknowledgement, acceptance, rejection and follow-up information around each submission.
Use the transition period to build a better filing process.
Map the companies and account types you manage.
Centralise statutory dates and filing responsibility.
Test the software workflow before the deadline becomes urgent.
Move into 2028 with a portfolio process already in daily use.
Before you start.
Current Companies House guidance states that all companies will need to file annual accounts using commercial software from 1 April 2028. Users should continue checking GOV.UK guidance because implementation details can change.
The page recommends preparing earlier so portfolio, deadline, authority and filing workflows can be tested before the transition date.
