What happened to MTD for Corporation Tax
Making Tax Digital for Corporation Tax (MTD for CT) was planned as the next major step in HMRC’s drive to modernise tax reporting for UK businesses.
However, the government has now confirmed that MTD for Corporation Tax will not be introduced. This means limited companies can continue filing Corporation Tax returns using the existing HMRC online service, without the need for MTD-compatible software.
While this change removes one expected compliance burden, digital record-keeping still offers big advantages. By keeping accurate electronic records and using accounting software, your company can reduce errors, improve efficiency, and stay ready for any future updates to HMRC systems.
This guide explains:
- What MTD for Corporation Tax was intended to involve
- Who would have been affected
- Why it’s no longer going ahead
- What limited companies should focus on now to stay efficient and compliant
What was MTD for Corporation Tax?
Making Tax Digital for Corporation Tax (MTD for CT) was HMRC’s proposed plan to modernise how incorporated businesses, mainly limited companies, managed their tax records and submissions.
If introduced, MTD for Corporation Tax would have required companies to:
- Maintain digital records of income, expenses, and tax calculations throughout their accounting period.
- Use MTD-compatible software to prepare and submit Corporation Tax returns directly to HMRC.
- Replace the current CT600 (Corporation Tax Return) paper or online form with a fully digital submission process.
The aim was to make Corporation Tax reporting more accurate, efficient, and transparent by cutting down on errors, removing manual processes, and giving HMRC a clearer view of company tax positions in real time.
However, the UK government has confirmed that MTD for Corporation Tax will not be implemented. Businesses should continue filing Corporation Tax returns using the existing CT600 system via HMRC’s online services.

When Will MTD for Corporation Tax Start?
Making Tax Digital for Corporation Tax (MTD for CT) was originally in development, with HMRC running consultations and a pilot scheme. However, the government has now confirmed that MTD for Corporation Tax will not be introduced.
Here’s a quick look at the key milestones that led to this decision:
| Year | Status |
| 2021 | HMRC completed its consultation on the MTD for CT framework |
| 2024 | Pilot scheme ran with voluntary companies testing MTD-compatible processes |
| 2025 | Government confirmed it would not move forward with MTD for Corporation Tax |
Key point: Limited companies will continue to file Corporation Tax returns using the current CT600 system via HMRC’s online services. While MTD for CT is no longer happening, adopting digital record-keeping and accounting software can still help streamline compliance and improve accuracy.
