HMRC has confirmed that its joint online filing service, which currently allows limited companies to submit both accounts and Company Tax Returns simultaneously to Companies House and HMRC, will be shutting down on 31 March 2026.

Starting 1 April 2026, businesses will be required to file their annual accounts with Companies House using third-party software, web services, or paper filing. However, Company Tax Returns will need to be filed using software with HMRC.

Why is the service closing?

The closure is part of HMRC's initiative to modernize its system and align it with updated digital standards, as well as changes in UK company law. The current service no longer meets the requirements of the Economic Crime and Corporate Transparency Act (ECCT Act). The change also supports the implementation of new measures, such as identity verification, to combat economic crime.

What should companies do now?

If your company has been using the joint service, it's essential to begin saving the last three years' worth of filings. After 1 April 2026, you will no longer be able to access these records through the current platform.

This is the perfect time to consider moving to an online accounting software provider (like Crunch!). We offer easy-to-use software that allows businesses to manage both Companies House accounts and Company Tax Returns with HMRC seamlessly. Transitioning to this software now will ensure your business is fully prepared for the upcoming changes and able to submit filings efficiently.

The move to a fully digital filing system

This shift to software-only filings aligns with HMRC’s broader push to enhance its digital services and modernize the filing process. From 2026, all businesses will need to use third-party software to submit their Company Tax Returns to HMRC. While paper filing will still be an option for submitting accounts to Companies House, software will be required for the submission of Company Tax Returns to HMRC.

The change also supports the UK government's efforts to combat economic crime and modernise the country’s filing practices to meet international standards. Given the advanced notice, now is the ideal time for businesses to start planning and make sure they’re ready for this digital transition.
