Built to run where your data already lives

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.

Key Features

Everything you need for compliant VAT submission

A complete Making Tax Digital solution, designed specifically for businesses already running on IBM i.

Direct HMRC Integration

Submits VAT returns straight from your IBM i system to HMRC's MTD API, with no intermediate export or upload step.

Automated VAT Returns

Pulls figures from your existing IBM i data, builds the return automatically, and schedules submission ahead of deadlines.

Real-Time Compliance Monitoring

Checks submissions against HMRC requirements as they're prepared, flagging issues before they ever leave your server.

Full Audit Trail

Every return, response and resubmission is logged on the IBM i system, giving you a complete record for HMRC and internal audit.

Secure Data Transmission

VAT data is encrypted in transit between your IBM Power server and HMRC. Nothing is staged or stored off-platform.

No New Infrastructure

Runs on the IBM Power hardware you already operate. No cloud subscription, no separate server, no new platform to manage.

How It Works

From your IBM i system to HMRC, in four steps

The portal sits alongside your existing applications and data — it doesn't replace them.

1

Install on your IBM Power server

The MTD VAT Portal is deployed directly onto your existing IBM Power hardware, running natively under IBM i alongside your current applications.

2

Connect to your VAT data

The portal reads VAT-relevant figures directly from your IBM i database — no manual re-keying, exports or spreadsheets required.

3

Validate & review

Returns are checked against HMRC's Making Tax Digital rules before submission, with a clear review screen for your finance team.

4

Submit & record

The return is transmitted securely to HMRC, and the response and full audit trail are written straight back into IBM i.
