HMRC Joint Filing Service Closed — What UK LTD Owners Must Know in 2026
<![CDATA[
As of 31 March 2026, HMRC has permanently closed the Joint Filing Service that allowed companies to submit their Annual Accounts and Company Tax Return (CT600) together through a single portal. This change affects every UK limited company — including those owned by non-residents.
What Changed?
Previously, small companies could use the HMRC- Companies House joint filing service to submit:
- Annual Accounts to Companies House
- Company Tax Return (CT600) to HMRC
— all in one go. That option no longer exists.
What You Must Do Now (from April 2026)
| Filing | Submit To | Deadline |
|---|---|---|
| Annual Accounts | Companies House (WebFiling or software) | 9 months after ARD |
| CT600 + Computations | HMRC (CT Online or software) | 12 months after ARD |
| Confirmation Statement | Companies House | Annually (review period) |
Why This Matters for Non-Resident LTD Owners
If you are a Polish entrepreneur with a UK limited company, the closure of the joint filing service adds complexity:
- Two separate systems — Companies House and HMRC have different login credentials, different interfaces, and different filing formats.
- Double the risk of errors — data must be consistent across both filings, but you now enter it twice.
- Historic returns inaccessible — HMRC has warned that previously filed joint returns are no longer accessible through the service. You need proper record-keeping.
Upcoming: P&L Filing for Small Companies (2028)
Under the ECCTA reforms, from 2028 even micro-entities and small companies will be required to file a Profit & Loss account with Companies House — not just the balance sheet. This is a significant change from the current regime where small companies only file an abridged balance sheet.
