AccountsOS Now Submits Your VAT Returns Directly to HMRC (MTD for VAT, Live)

Since April 2022, every VAT-registered business in the UK has had to keep digital records and file VAT returns through MTD-compatible software. There is no longer a "type it into the HMRC website" option. So the only real question for a VAT-registered founder is which software does it — and how much work it leaves on your plate.

As of today, AccountsOS is one of them. And it does the VAT return for you, rather than handing you a form to fill in.

What's live

You can now, inside AccountsOS:

1. Connect your HMRC account — a one-time secure authorisation. Settings → Integrations → HMRC MTD.
2. See your VAT obligations — Finn pulls your open and fulfilled VAT periods straight from HMRC, so you always know what's due and when.
3. Submit your VAT return directly to HMRC — Finn builds the nine boxes from your bookkeeping, shows you the figures, and on your confirmation submits them to HMRC under MTD.

This is the real HMRC production service, not a sandbox demo. The connection, the obligations and the submission all run against HMRC's live MTD for VAT API.

What makes this different from bridging software

Most "MTD VAT" tools are really one of two things: a glorified spreadsheet you still fill in by hand, or a bridging tool that shovels a spreadsheet's totals into HMRC. Both leave the actual work — categorising transactions, working out which VAT scheme applies, getting the nine boxes right — with you.

AccountsOS closes the loop:

• Digitally linked end to end. Your bank transactions, receipts and invoices flow into the ledger, the ledger produces the VAT return, and the return goes to HMRC. There's an unbroken digital link the whole way, which is exactly what MTD asks for — and there's no spreadsheet in the middle.
• The nine boxes are calculated, not typed. Finn computes Box 1 to Box 9 from your records, including standard and flat-rate scheme handling. You're checking a number, not assembling it.
• Finn watches the deadline. Your VAT obligations are tracked automatically, so the return surfaces before it's due instead of after.

You stay in control

Nothing is submitted to HMRC without your say-so. Finn prepares the return and shows you every figure; you confirm, and only then is it sent. The submission, the receipt and the obligation status are all visible in the app afterwards. Finn does the preparation — you make the call.

Which VAT schemes are supported

AccountsOS handles Standard VAT accounting and the Flat Rate Scheme, including the nine-box calculation differences between them. If you're not sure which scheme saves you the most, see our VAT schemes comparison, or just ask Finn.

How to switch your VAT filing to AccountsOS

1. Start a free trial (14 days, no card) or log in.
2. Go to Settings → Integrations and connect HMRC MTD.
3. Import or connect your bookkeeping — bank feed, CSV or PDF statements, plus receipts from any channel. Finn categorises as it goes.
4. When your VAT period is due, open the return, check Finn's figures, and submit.

That's it. Your next VAT return goes to HMRC from AccountsOS, and Finn does the assembly.
