No cloud migration. No third-party hosting. No data leaving your business. Our VAT submission engine is installed directly onto your existing IBM Power server, running natively under the IBM i operating system — built to fit straight into the platform you already trust.
The MTD VAT Portal is installed directly on your IBM Power server and executes natively under the IBM i operating system. There's no separate appliance, no hosted middleware and no requirement to export your VAT data to a third-party cloud platform before it reaches HMRC.
A complete Making Tax Digital solution, designed specifically for businesses already running on IBM i.
Submits VAT returns straight from your IBM i system to HMRC's MTD API, with no intermediate export or upload step.
Pulls figures from your existing IBM i data, builds the return automatically, and schedules submission ahead of deadlines.
Checks submissions against HMRC requirements as they're prepared, flagging issues before they ever leave your server.
Every return, response and resubmission is logged on the IBM i system, giving you a complete record for HMRC and internal audit.
VAT data is encrypted in transit between your IBM Power server and HMRC. Nothing is staged or stored off-platform.
Runs on the IBM Power hardware you already operate. No cloud subscription, no separate server, no new platform to manage.
The portal sits alongside your existing applications and data — it doesn't replace them.
The MTD VAT Portal is deployed directly onto your existing IBM Power hardware, running natively under IBM i alongside your current applications.
The portal reads VAT-relevant figures directly from your IBM i database — no manual re-keying, exports or spreadsheets required.
Returns are checked against HMRC's Making Tax Digital rules before submission, with a clear review screen for your finance team.
The return is transmitted securely to HMRC, and the response and full audit trail are written straight back into IBM i.
IBM i was built for resilience and security. Keeping VAT submission on the same platform keeps those guarantees intact.
