MTD for VAT Software UK 2026: Submit Your VAT Return Directly to HMRC

MTD for VAT software is software that meets HMRC's Making Tax Digital requirements: it keeps your VAT records in a digital format, maintains digital links between those records and your return, and submits the return to HMRC through HMRC's MTD VAT application programming interface (API). The software connects to HMRC directly, so when you file, the figures go straight into HMRC's systems and you get a confirmation receipt back.

This is different from simply typing nine numbers into a website. Under MTD, the figures on your VAT return must flow from your underlying records through unbroken digital links, with no manual retyping or copy-and-paste of the totals. The software is what enforces and proves that chain.

There are two broad types. Full accounting software keeps all your records, categorises transactions, and calculates the return for you. Bridging software does none of the bookkeeping and only takes figures from a spreadsheet and pushes them to HMRC. AccountsOS is full accounting software with an AI layer that does the categorising and the calculation for you.

Yes. For all VAT-registered businesses, the VAT return must be submitted through MTD-compatible software. HMRC closed the old online VAT return portal for routine filing, and new VAT registrations are signed up to MTD automatically unless they hold an exemption.

There is no turnover threshold any more. The rule used to apply only above the VAT registration threshold, but since April 2022 it covers every VAT-registered business, including those registered voluntarily below the threshold.

The only routes that do not require software are a small set of HMRC exemptions, for example where you are digitally excluded by age, disability, location, or a religious objection. You have to apply to HMRC for an exemption; it is not automatic.

The legal minimum is that the software can keep digital records and file to HMRC. But that minimum still leaves you doing all the work. The features that actually save you time are the ones worth paying for.

Use the checklist below when comparing tools. The biggest difference between a cheap filing tool and genuinely useful software is how much of the bookkeeping it removes from your plate.

AccountsOS is MTD-compatible software built to HMRC's Making Tax Digital VAT API specification. It does the whole VAT cycle, not just the final submit.

Through the quarter, every transaction is captured digitally with the original receipt or invoice attached, and the AI categorises it and works out the VAT treatment. You can forward a receipt by email or send it to Finn, the AI accountant, on WhatsApp, and it is logged against the right transaction automatically. The VAT 9-box return is recalculated live as you go, so at any point you can see exactly what you owe.

When the period ends, you review the nine boxes, then submit directly to HMRC under MTD. You can do this from the VAT screen in a couple of clicks, or simply ask Finn in chat to file it, and it will confirm the figures with you before sending. AccountsOS stores HMRC's confirmation receipt and form bundle number against the period, so you have proof of filing.

Because the calculation engine and the submission use the same figures, the 9-box you review is the 9-box that gets filed. There is no re-keying and no separate bridging step.

Xero and QuickBooks are the best known all-in-one tools and both file VAT to HMRC under MTD. The difference with AccountsOS is the AI layer: instead of you sitting in front of a dashboard categorising transactions and chasing receipts, the software does that work and you review the result.

Prices below are indicative at the time of writing and exclude VAT where noted. Always check the current price with each provider.

Costs range from free to around twenty to forty pounds a month. Free is real but limited: it usually ties you to a specific bank, leaves you doing all the bookkeeping by hand, and comes with little or no support.

The honest way to compare is total cost, which means the software price plus the time you spend doing the work the software does not. A tool that is five pounds cheaper but makes you spend three evenings a quarter categorising transactions is not cheaper.

You do not have to wait for a new VAT period to switch. AccountsOS can import your existing transactions, whether they live in a spreadsheet or in another accounting tool, and the AI maps your data onto the right categories so your records are continuous.

Once you are in, you connect to HMRC once through a secure authorisation, and from then on filing is part of the normal flow. Your VAT history and prior returns stay intact, and the next return is calculated from your live data.

AccountsOS is built for founders and small businesses who would rather not spend their time on bookkeeping. If you are VAT-registered, want your records kept properly without doing the data entry yourself, and want to file to HMRC without thinking about it, it is a strong fit.

If you have a finance team that wants to drive every entry by hand, or you only ever need to press submit on a spreadsheet you maintain yourself, a bridging tool may be enough. For everyone else, the value is in the work AccountsOS removes, not just the filing button.

You can try it free for 14 days with no card, connect your data, and see your live VAT position before you decide.
