Your Free VAT Software Has a Blind Spot It Didn't Have in 2019

Since April 2019, you have been a model digital taxpayer. Your VAT returns go in quarterly, on time, through whichever free or near-free software you found when HMRC first mandated Making Tax Digital for VAT. You did not grumble. You digitised. And for seven years, that was enough.

Then April 2026 arrived. HMRC did not send a letter. Your software did not update its interface. The quarterly VAT submission went in as usual. But somewhere in HMRC's systems, a second compliance clock started ticking, one that vat software free of charge was never built to stop.

If you are a VAT-registered sole trader with turnover above £50,000, you now have two separate MTD obligations. Your free VAT software handles exactly one of them.

What Free VAT Software Was Built to Do

When HMRC launched Making Tax Digital for VAT in April 2019, the mandate was narrow: VAT-registered businesses with taxable turnover above the registration threshold had to keep digital records and submit VAT returns through MTD-compatible software rather than the old online portal. That was the entire requirement. One obligation. One submission type. Four returns per year.

The software market responded with a wave of free and near-free tools: bridging utilities that connected spreadsheets to HMRC's MTD VAT API, FreeAgent made available free with certain NatWest and RBS business bank accounts, QuickFile's free tier for smaller businesses, and a handful of stripped-back submission tools designed to do exactly one thing at minimal cost.

These tools work. If you have been using free VAT software since 2019, your quarterly VAT returns are almost certainly landing correctly in HMRC's system. The issue is not with what the software does. The issue is with what it has never been designed or required to do.

MTD for VAT software submits your quarterly VAT return. It captures input tax, output tax, and the nine return boxes. It does not know your gross trading income. It does not track your allowable business expenses. It has never needed to, because until April 2026, HMRC did not require self-employed sole traders to report that information digitally on a quarterly basis. You found the right tool for a specific job, used it correctly, and stayed compliant. The problem is that the job changed around you, without any clear signal from the software that something new was now missing.

April 2026 and the Second Obligation

From 6 April 2026, HMRC introduced a second wave of digital compliance for self-employed individuals earning above £50,000 per year. This is Making Tax Digital for Income Tax Self Assessment, commonly shortened to MTD ITSA. It is an entirely separate regime from MTD for VAT, with different submission requirements, a different HMRC API, different record-keeping standards, and its own penalty structure.

Under MTD ITSA, a sole trader above the threshold must now:

• Maintain digital records of business income and expenses throughout the tax year
• Submit four quarterly updates to HMRC showing cumulative income and expenses for each quarter
• File an End of Period Statement at the close of the tax year
• Submit a Final Declaration, replacing the old Self Assessment tax return

That is up to six separate MTD ITSA submissions per year, in addition to four quarterly VAT returns for those who are VAT-registered. Ten HMRC submissions in total, annually. Free VAT software, by design, handles four of them.

The confusion between the two regimes is entirely understandable. HMRC named both of them "Making Tax Digital." The software interfaces look similar even when the underlying submissions do not. And the government's communications around MTD ITSA have been considerably quieter than the original MTD for VAT rollout, perhaps because HMRC was aware that asking the same audience to comply a second time required careful handling.

Many sole traders who searched vat software free in 2019, installed a bridging tool, and moved on have had no particular reason to revisit the question since. Their software continues to work. Their VAT returns arrive on time. Nothing in their inbox suggests anything is wrong. What their inbox does not show is the separate income tax MTD account, and the quarterly updates that have not appeared in it since April.

The Gap in Concrete Terms

Here is what the gap looks like for a typical affected sole trader.

Marco is a self-employed electrician. He turned over £72,000 in the 2025 to 2026 tax year. He registered for VAT when his turnover crossed the registration threshold several years ago and set up a free bridging tool to handle his quarterly VAT submissions. He has never missed a VAT return and has received no penalty notices of any kind.

From April 2026, Marco is also within scope for MTD ITSA. His first quarterly income update, covering April to June 2026, was due by 5 August 2026. His free VAT software submitted his Q1 VAT return correctly. It submitted nothing else, because it has no mechanism to do so. Marco's VAT account at HMRC shows everything as expected. His income tax account under MTD ITSA shows no quarterly update received for that period.

The penalty regime for MTD ITSA operates on a points-based model. Missing a quarterly update earns one penalty point. Accumulating four points within a 12-month period triggers a £200 fixed penalty, with further charges for continued non-compliance beyond that. Marco, filing VAT correctly through free software while unknowingly missing his MTD ITSA submissions, accumulates points with no visible warning from HMRC, no error message from his software, and no indication in his VAT account that anything is wrong.

This is not a theoretical scenario. It is the live situation for any VAT-registered sole trader who searched for vat software free, found a VAT-only tool, and assumed that covered their Making Tax Digital obligations in full. That assumption was correct until April 2026. It is no longer correct now.

Who Falls Into This Trap Most Easily

The profile of the sole trader most at risk is fairly specific: someone who has been VAT-registered for several years and resolved their MTD VAT compliance when it first became mandatory. They solved the problem once, moved on, and have not revisited their software setup since.

They typically earn between £50,000 and £120,000, which places them above the MTD ITSA threshold but below the level at which most businesses retain a dedicated accountant monitoring every regulatory change. Trades are heavily represented: electricians, plumbers, construction workers, decorators, IT contractors, and similar self-employed individuals who cross the VAT registration threshold through volume of work rather than premium pricing.

The risk is lower for those using full-service accounting platforms such as Xero, QuickBooks, or FreeAgent on a paid subscription, because those platforms have been building MTD ITSA functionality and will generally prompt users when new obligations apply. The risk is concentrated among those who found the cheapest, lightest-touch VAT submission tool in 2019 and stopped there. Those tools are, almost by definition, the ones that dominate results when you search vat software free today.

If you are uncertain which category your setup falls into, the test is simple: open your current VAT software and look for any reference to income tax submissions, MTD ITSA, quarterly income updates, or End of Period Statements. If the interface shows nothing beyond VAT return fields and your submission history shows only VAT returns, you have found the gap.

What "Free VAT Software" Returns in 2026

Search "vat software free" in September 2026 and the results are dominated by bridging tools, accounting platforms promoting free trials, and FreeAgent's bank partnership pages. Nearly everything that appears is VAT-focused. Some full-service platforms include MTD ITSA capability within a broader paid subscription; none of the genuinely free tools cover both regimes reliably.

This is not a coincidence. MTD ITSA is a considerably more complex technical undertaking than a VAT return submission. It requires software to categorise income and expenses, communicate with HMRC's income tax API (which is separate from and distinct to the VAT API), and maintain digital records across a full tax year rather than a single quarter. Building a free tool that covers both obligations is not commercially viable for software vendors when a monthly subscription model exists for the combined product.

The practical result is a market where free VAT software exists, works, and handles your VAT obligations correctly, while free MTD ITSA software for sole traders who want to self-file is close to nonexistent. As Free Tax Return Software: The Government Tool HMRC Never Built sets out, HMRC chose not to build a free government filing tool for MTD ITSA, meaning the cost of compliance falls entirely on the taxpayer or their chosen software vendor.

What VAT-Registered Sole Traders Should Do Now

The steps are practical and do not require dismantling everything immediately.

Confirm what your current software actually submits. Log in and check your submissions history. If every entry is a VAT return, your income tax MTD compliance is unaddressed. Most bridging tool providers will confirm this directly if you contact their support.

Check whether you are within scope. MTD ITSA applies to self-employed individuals with qualifying income above £50,000 from April 2026. If your income sits below that level, you are not yet affected, though the obligation drops to £30,000 from April 2027. Self Assessment Software Free: The Deadline That Changes Everything sets out the threshold timeline clearly for those approaching either boundary.

Review your first MTD ITSA quarterly deadline. Quarterly updates are due one month and seven days after each quarter closes. For the standard April-to-March tax year, those deadlines fall on 5 August, 5 November, 5 February, and 5 May. If you missed the August deadline for Q1, a penalty point may already be on your record.

Find software that covers both obligations without starting from scratch. Options range from full-service accounting platforms to simpler tools built specifically for self-employed sole traders navigating both VAT and income tax MTD compliance. TapTax is designed for exactly this position: a VAT-registered sole trader who needs to remain compliant on both fronts without the overhead of a full accounting suite or the ongoing cost of delegating everything to an accountant. The quarterly submission process is kept as close as possible to the familiar VAT filing experience you have already been using.

For those weighing whether to handle both obligations independently or consolidate to one platform, Sole Trader Accounting Software: Price It by the Hour gives a practical framework for the comparison. For a broader view of how MTD software has held up since the income tax rollout began, Tax Digital Software Had Its First Real Test. Did Yours Pass? is worth reading before committing to any tool.

The Broader Lesson

HMRC built two separate Making Tax Digital regimes across seven years, gave them similar names, and did little to clarify to taxpayers who were already compliant on one side that something new had arrived on the other. The result is a cohort of sole traders who followed the rules, found vat software free to use, and now sit with a silent compliance gap they cannot see from their existing dashboard.

The 2019 search that solved your problem has not stopped working. Free VAT software still submits VAT returns accurately. The gap is not that the tool failed. The gap is that HMRC added a second obligation, the software market did not extend its free tier to cover it, and no one sent a clear signal that the job had grown.

Seven years of timely, accurate VAT submissions deserves better than an invisible new obligation accruing penalty points in a separate HMRC account. Check what your software actually submits. Check whether any MTD ITSA quarterly updates appear in your income tax record. Then choose a tool that covers both before HMRC's points system does the calculation for you.
