KEYinfinity and KEYPrime recognised for MTD IT: a positive step forward

As we start the new year, we’re pleased to share some important news that marks a significant milestone for our software and our existing customers.

Both KEYinfinity and KEYPrime have now been officially recognised by HMRC for Making Tax Digital for Income Tax (MTD IT). This confirms that both products meet HMRC’s requirements for digital record-keeping and the direct submission of Income Tax updates, including the four mandatory quarterly submissions.

With the April 2026 MTD IT deadline approaching, this recognition provides reassurance that businesses using KEYinfinity and KEYPrime are fully supported and prepared for the upcoming changes. It ensures that your software is compliant, future-ready, and aligned with HMRC’s digital tax reporting standards.

For our customers, this brings real peace of mind. Knowing that their accounting software is officially recognised means that they can continue managing their financial records with confidence, without the worry of last-minute changes or disruption as the new requirements come into force.

At Landmark Systems, we’re proud to continue investing in our products to ensure they evolve alongside regulatory changes, helping our customers stay compliant while focusing on running their businesses.

If you aren’t currently using either of these software solutions and if MTD for Income Tax will apply to your business, contacting the specialist team at Landmark Systems ahead of April can help ensure the right systems and processes are in place, avoiding unnecessary pressure as the deadline approaches.
