VAT Returns and MTD: What Changes for Sole Traders in 2026

If you registered for VAT before April 2022, Making Tax Digital for VAT has already changed how you file your VAT returns, whether you realised it or not. For anyone who signed up after that date, the same rules applied from day one. And yet a surprising number of sole traders are still filing through workarounds, spreadsheets bridged by third-party software, or software they barely understand, paying for features they will never use. This post is not about what can go wrong when you submit (that's covered in VAT Return Submission: What Goes Wrong and Why). This is about understanding how VAT returns fit into the broader MTD picture as the Income Tax rules arrive in April 2026, and what that means in practical terms for a sole trader who is already juggling VAT quarterly deadlines on top of everything else.

VAT Return

A form submitted to HMRC, usually every quarter, that records the VAT you have charged customers (output tax) and the VAT you have paid on business purchases (input tax). The difference is what you owe HMRC, or what HMRC owes you as a repayment. Under Making Tax Digital for VAT, these must be submitted digitally using HMRC-compatible software.

Two Tax Obligations, One Sole Trader, Zero Sympathy From the Calendar

Here is the administrative reality for a VAT-registered sole trader turning over, say, £65,000 a year. You are already committed to four VAT returns annually, each due one month and seven days after the end of your VAT quarter. Miss the deadline and HMRC's penalty points regime kicks in: two points for a second late submission, a £200 fine for a third, and another £200 for every late return after that.

From April 2026, that same sole trader will also face four quarterly updates under MTD for Income Tax, plus a final annual tax return by 31 January. That is effectively eight or nine separate filing events a year, spread across a calendar that has no interest in your busy season, your family commitments, or the fact that your accountant is on holiday in August.

This is not scaremongering. It is arithmetic. And it is worth understanding now, before April 2026 arrives and the Income Tax obligations stack on top of the VAT ones you are already managing.

What MTD for VAT Actually Requires You to Do

Making Tax Digital for VAT, introduced under the Value Added Tax (Amendment) Regulations 2019, requires two things. First, you must keep digital VAT records. Second, you must submit your VAT returns using software that connects directly to HMRC's API, not by logging into the Government Gateway and typing numbers in manually.

The digital records requirement is broader than most people realise. It covers the time and date of supply, the net value and VAT rate for each transaction, and details of any VAT accounting schemes you use. HMRC does not require you to keep a digital record of every individual receipt for Income Tax purposes under the current VAT rules, but you do need a digital audit trail that your software can draw on when it populates your VAT return.

What HMRC does not require, despite what some software vendors imply, is a specific type of software. Any HMRC-recognised product that connects to their API will do. The question is whether that product also handles the Income Tax side of your obligations, and whether you are paying a sensible price for it.

The Bridging Software Problem

When MTD for VAT launched in 2019, thousands of sole traders and small businesses opted for what HMRC grudgingly permitted: bridging software. You keep your records in a spreadsheet, run a bridging tool on top, and that tool submits the VAT return digitally. Technically compliant. Practically, a faff.

The problem with bridging software is not just the extra step. It is that it teaches you nothing about digital record-keeping and leaves you entirely unprepared for MTD for Income Tax, which requires a fundamentally different relationship with your financial data. Quarterly Income Tax updates need categorised income and expense records, not a single spreadsheet row of VAT totals. If you are still using bridging software in 2025, you are storing up a painful transition for yourself.

VAT Quarters and MTD Income Tax Quarters: Do They Align?

This is a question that sole traders almost never think to ask until they are drowning in deadlines, and the answer is: not automatically.

Your VAT quarter is determined by when you registered for VAT and which stagger group HMRC assigned you to. Most sole traders end up with quarters finishing in March, June, September, and December, or one month offset from those. MTD for Income Tax quarterly updates, by contrast, follow the tax year: periods ending 5 July, 5 October, 5 January, and 5 April.

So if your VAT quarter ends 31 March and your MTD Income Tax period ends 5 April, you are filing two separate submissions within eleven days of each other, covering different periods, calculated on different bases. One is a VAT calculation (output tax minus input tax). The other is a summary of your business income and allowable expenses for Income Tax purposes.

They are not the same numbers. They are not drawn from the same totals. And yet they both rely on the same underlying transaction records. This is precisely why the software you choose matters: good MTD software maintains a single set of records from which it can generate both reports without you re-entering anything.

The Annual Tax Return Has Not Gone Anywhere

One myth worth killing directly: the Self Assessment tax return is not being abolished. MTD does not replace it. What changes is how you submit it (through compatible software rather than the Government Gateway SA form) and the fact that quarterly updates mean HMRC has a running picture of your income before January.

For a VAT-registered sole trader joining MTD for Income Tax in April 2026, the timeline works like this. The 2025-26 tax year is filed the usual way, by 31 January 2027, as normal. From April 2026 onwards, you file quarterly Income Tax updates and then a final annual tax return covering the full year, still due by 31 January the following year. The quarterly updates are not returns; they are summaries. You are not paying tax four times a year. You are reporting four times a year so that HMRC can see your position in something closer to real time.

If that sounds manageable, it is, provided your records are clean and your software is doing the heavy lifting.

People also ask

Do VAT returns change under MTD for Income Tax from 2026?

No. MTD for Income Tax introduces quarterly Income Tax updates that run alongside your existing VAT return obligations. VAT returns themselves are unchanged; the new layer is the Income Tax reporting, which uses categorised income and expense records rather than VAT totals.

What happens if I miss a VAT return deadline?

Under HMRC's penalty points system, introduced in January 2023, you accumulate one point per late VAT return. At two points you receive a £200 fine; each subsequent late return adds another £200. Points expire after a period of compliance, but the fines are charged immediately once the threshold is reached.

Can I use the same software for VAT returns and MTD Income Tax?

Yes, and this is the most efficient approach. Software that handles both obligations draws on the same transaction records to generate your VAT return and your quarterly Income Tax updates, eliminating double-entry and reducing the risk of inconsistencies between the two sets of figures.

Is the annual Self Assessment tax return still required under MTD?

Yes. MTD for Income Tax does not abolish the annual tax return. You still submit a return by 31 January after the tax year ends. The quarterly updates are summaries that keep HMRC informed during the year, but the final tax calculation is confirmed through the annual return.

What Good VAT Record-Keeping Actually Looks Like in Practice

Take a self-employed electrician turning over £72,000 a year, VAT-registered on the standard scheme, with a quarter ending 30 June. By 7 August, she needs to have submitted her VAT return covering April, May, and June. That means every invoice she raised, every material she purchased, every tool she bought with VAT on it needs to be categorised and totalled.

If she is using software that imports her bank statement via CSV (categorising income and expenses as she goes), that VAT return takes her about twenty minutes at the end of the quarter. If she is manually entering transactions from a shoebox of receipts in late July, it takes considerably longer and the error rate rises sharply.

The same transaction records that populate her VAT return will, from April 2026, also feed her quarterly MTD Income Tax updates. She is not doing twice the work. She is doing the same work once and letting software produce two different outputs from it. That is the actual value proposition of compliant bookkeeping software, and it is why getting your records in order before 2026 is not just box-ticking; it is a genuine time saving.

If you are currently paying for software that does not cover both obligations, it is worth reading MTD Software for Small Business: Stop Paying for Features You'll Never Use before your next renewal date.

The Cash Flow Dimension Nobody Mentions

VAT returns have a cash flow dimension that Income Tax updates do not, and it is worth being explicit about it. When you submit a quarterly VAT return showing net VAT due, payment is required by the same deadline (one month and seven days after the quarter end, with an extra three calendar days for direct debit). That is a real cash outflow, not a notification.

For a sole trader on the standard VAT scheme charging 20% VAT, the quarterly bill can be substantial. An electrician billing £18,000 net in a quarter, with £3,000 in VATable business purchases, owes HMRC £3,000 in VAT for that period. That money needs to be in the business account or set aside in advance.

The Monthly VAT Returns: When Paying HMRC More Often Saves You Money post covers one specific cash flow strategy. But the broader point is that VAT return management is partly a planning exercise. Knowing your running VAT position at any point in the quarter, rather than discovering it in a panic when the return is due, is one of the genuine advantages of keeping live digital records throughout the period rather than reconciling at the end.

Choosing Software That Covers Both Bases

The practical upshot of everything above is that a VAT-registered sole trader approaching 2026 needs software that can do three things without requiring separate systems or manual bridges.

First, it needs to maintain categorised digital records that satisfy MTD for VAT requirements: transaction by transaction, with the correct VAT rates applied and a clear audit trail.

Second, it needs to populate a VAT return in the correct nine-box format and submit it directly to HMRC through the API, not via a bridging tool.

Third, from April 2026, it needs to generate quarterly Income Tax updates from the same underlying records and submit those to HMRC through the MTD for Income Tax API.

TapTax is built to handle all three. You import your bank statement by CSV (with presets for 16 UK banks, included on every plan), categorise your transactions, and the software handles both your VAT return and your quarterly Income Tax submissions from a single set of records. No bridging software. No duplicate entry. No separate system for VAT and a different one for MTD Income Tax.

For a sole trader who wants to spend as little time as possible on tax admin without getting it wrong, that consolidation is worth more than any individual feature on a competitor's list.

If you are evaluating options, the Bookkeeping Software for Sole Traders: Pay Less, Get More post provides a useful framework for thinking about what you actually need versus what vendors want to sell you.

The Bottom Line on VAT Returns and MTD

Remember the question this post opened with? If you registered for VAT before April 2022, MTD for VAT has already changed how you file. The question now is not whether you are compliant with MTD for VAT (you should be), but whether the system you are using is going to hold up when the Income Tax obligations arrive in April 2026.

Four VAT returns a year plus four Income Tax updates plus one annual tax return is a manageable workload, but only if your underlying records are clean and your software is doing the work of translating those records into the right format for each submission. If your current setup requires manual bridging, duplicate entry, or end-of-quarter panic, the time to fix it is before 2026 adds another layer on top.

One concrete action you can take today: check whether your current software is recognised for MTD for Income Tax as well as MTD for VAT. HMRC's list of HMRC recognised software is not a guarantee of usability, but it is the minimum bar. If your current tool is not on it for both obligations, you have a decision to make before April 2026.
