If you run a VAT-registered business in the UK — whether you're a freelance consultant in Manchester, a plumber in Bristol, or a market trader in Edinburgh — Making Tax Digital for VAT affects you directly. HMRC's MTD programme has been rolling out since 2019, and by 2026 there are no exceptions left. Every VAT-registered sole trader must keep digital records and file returns through MTD-compatible software. No bridging spreadsheets. No logging into the old HMRC portal and typing figures in by hand. The old ways are gone.
The good news? Once you understand what MTD for VAT actually requires, compliance is far more straightforward than the acronym suggests. This guide walks you through the essentials in plain English.
What Is Making Tax Digital for VAT — and Why Does It Exist?
Making Tax Digital is HMRC's long-term strategy to digitise the UK tax system. The theory is simple: digital records are more accurate than paper ones, errors cost the Treasury billions each year (HMRC estimates the "tax gap" at around £36 billion annually), and software can catch mistakes that humans miss.
For VAT specifically, MTD means two things. First, you must keep your VAT records in a digital format throughout the accounting period. Second, you must submit your VAT return to HMRC directly from that digital software using HMRC's API — not by copying figures into a web form.
MTD for VAT first applied to businesses with taxable turnover above the £85,000 VAT threshold in April 2019. It was extended to all VAT-registered businesses — including those voluntarily registered below the threshold — in April 2022. So if you registered for VAT voluntarily because it suits your business model, you have been in scope for several years already. There are no more grace periods or soft-landings to rely on.
What Counts as a "Digital Record" Under MTD?
This is where many sole traders trip up. Keeping a digital record does not simply mean scanning your receipts and emailing them to yourself. HMRC is specific about what information must be captured digitally for each supply you make or receive.
For each sale (output tax), you must record:
- The time of supply (tax point)
- The net value of the supply
- The rate of VAT charged
For each purchase (input tax), you must record:
- The time of supply
- The net value
- The amount of input tax you are claiming
You must also keep digital records of your VAT account — essentially the working calculation that reconciles your outputs and inputs to produce the nine boxes on your VAT return. Critically, there must be a digital link at every stage of that journey. You cannot, for example, export figures from your accounting software into a spreadsheet, manually adjust a cell, and then submit from the spreadsheet. That break in the digital chain is a compliance failure.
HMRC does allow certain adjustments — for partial exemption, for instance — to be made in a separate spreadsheet, provided a digital link (such as a formula or an automated data transfer) connects it back to your main records.
Choosing MTD-Compatible Software: What to Look For
The software market has matured considerably since 2019, and sole traders now have a wide range of options. HMRC publishes a list of recognised MTD-compatible software on its website, so that is always a sensible starting point. Beyond basic compliance, however, there are practical features worth prioritising.
Direct API submission is non-negotiable. Your software must be able to pull your VAT figures and push them to HMRC without you needing to copy anything manually. Some older or cheaper tools still rely on bridging software as an intermediary — an extra layer that introduces both cost and potential for error.
Automatic digital linking throughout your bookkeeping workflow saves considerable time. If your software connects your bank feed, categorises transactions, and populates your VAT account automatically, you satisfy the digital record requirement without any manual effort.
VAT scheme support matters if you use the Flat Rate Scheme, Cash Accounting Scheme, or Annual Accounting Scheme. Not all software handles these correctly — double-check before committing.
BizHub365, for example, integrates MTD VAT submission directly via HMRC's API, so sole traders can review their VAT return figures and submit in a few clicks without needing any bridging software at all. It also supports receipt scanning powered by AI, which captures the transaction data HMRC requires at the point of purchase — useful if you regularly buy materials or equipment on the go.
Penalties: What Happens If You Get It Wrong?
HMRC replaced the old default surcharge regime with a new points-based penalty system for VAT periods starting on or after 1 January 2023. Understanding how it works helps you avoid nasty surprises.
Late submission penalties operate on an accumulating points basis. Each missed submission deadline earns you one penalty point. Once you reach the threshold for your filing frequency — two points for annual filers, four points for quarterly filers — HMRC issues a £200 penalty. Every subsequent late submission while you remain at or above the threshold adds another £200.
Late payment penalties are separate and calculated as a percentage of the outstanding VAT:
- If you pay between 16 and 30 days late, a 2% penalty applies on the amount outstanding at day 15.
- If you pay 31 days or more late, a further 2% is charged on the amount outstanding at day 30, and daily interest accrues at the Bank of England base rate plus 2.5%.
There is also a late payment interest charge (separate from the penalty) that begins accruing from the payment due date. The message is clear: even a short delay can become expensive, particularly for sole traders managing cash flow tightly.
HMRC does provide a "period of familiarisation" concept for genuinely new processes, but do not bank on this. The MTD for VAT rules are well-established now, and HMRC's tolerance for avoidable non-compliance is shrinking.
Practical Steps to Get MTD-Ready Right Now
If you are not yet fully compliant — or you are not entirely certain that you are — here is a straightforward action plan.
- Confirm your VAT registration status. Log in to your HMRC Business Tax Account and check whether you have signed up for MTD for VAT. If you have not, do so immediately.
- Audit your current record-keeping. Are all your records genuinely digital? Are there any manual steps — even a copied-and-pasted figure — breaking your digital chain?
- Review your software. Check that it appears on HMRC's approved MTD software list and that it submits directly via API, not via bridging.
- Check your VAT scheme. Confirm your software correctly applies whichever VAT scheme you use, and test a return calculation before your next filing deadline.
- Set calendar reminders for submission deadlines. Quarterly returns are typically due one month and seven days after the end of each VAT period. Missing the deadline by even a day adds a penalty point.
- Talk to your accountant. If you use one, make sure they have agent authorisation through HMRC's MTD system, not just the old Government Gateway credentials.
Conclusion: MTD for VAT Is Here to Stay — Make It Work for You
Making Tax Digital for VAT is not going away, and the broader MTD programme — which will eventually cover Income Tax Self Assessment for sole traders from April 2026 — is only expanding. The businesses that thrive under MTD are the ones that stop treating it as a compliance burden and start treating it as an opportunity to get better visibility over their finances.
When your VAT records are genuinely digital and automatically reconciled, you always know where you stand. You can see your VAT liability building in real time, forecast your cash flow more accurately, and spend less time scrambling at filing deadlines. That is a genuine practical benefit, not just a regulatory checkbox.
If you are looking to simplify your MTD compliance from end to end — digital record keeping, direct HMRC submission, and AI-assisted receipt capture — it is worth exploring what BizHub365 offers at bizhub365.co.uk. Getting your VAT house in order now also puts you in the best possible position ahead of MTD for Income Tax, which will bring even more significant changes for sole traders in the years ahead.
