Best Free VAT Return Software Misses April 2026 Entirely

Since April 2026, HMRC has been running two separate Making Tax Digital compliance systems simultaneously. Most sole traders know about the first: Making Tax Digital for VAT, mandatory for all VAT-registered businesses since April 2022. Far fewer have registered for the second: Making Tax Digital for Income Tax, which became mandatory four months ago for every sole trader and landlord earning more than £50,000 a year. The two systems share a brand name and nothing else. Not the software. Not the submission calendar. Not the penalty regime.

If you searched for the best free VAT return software, you are solving a problem that became real in April 2022 when HMRC closed the free manual submission portal. That is a legitimate task. But it is increasingly the wrong question if you earn above the income tax MTD threshold, and the best free VAT return software available today leaves the more urgent compliance gap entirely unaddressed.

What HMRC Did in April 2022

Before April 2022, VAT-registered sole traders had two options for submitting quarterly returns. They could use accounting software, or they could log into HMRC's own Business Tax Account and submit manually through the Government Gateway portal. The manual portal was free, functional, and required no monthly subscription.

HMRC closed it.

From April 2022, the manual VAT submission option was withdrawn from all VAT-registered businesses, regardless of turnover. The reason HMRC gives is digital record-keeping: MTD for VAT requires businesses to maintain VAT records in a compatible digital format, with a direct digital link between those records and the return submitted to HMRC. A manual portal cannot verify that link exists. So HMRC removed it.

The consequence is that "best free VAT return software" is not a niche search. It is what every VAT-registered sole trader without an accountant now needs: software that connects digital records to HMRC's VAT API and submits the return. Several providers offer free tiers that do exactly this. Some are standalone VAT tools. Others are entry-level tiers of broader accounting platforms, with conversion to paid plans as the commercial model. A third category is bridging software, connecting a spreadsheet to HMRC's API via a digital link.

All of them solve the 2022 problem.

The Separate System Most VAT Software Does Not Know Exists

Four months ago, a second Making Tax Digital obligation went live. Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is mandatory from April 2026 for any sole trader or landlord whose total income from self-employment or property exceeds £50,000 in a tax year. From April 2027, that threshold drops to £30,000, pulling an estimated 300,000 additional sole traders into the system.

The filing structure under MTD ITSA looks like this: four quarterly updates covering income and expenses for each three-month period of the tax year, with submission deadlines on the 7th of the month following each quarter end; one end-of-period statement finalising the year's figures once all quarterly updates are submitted; and one final declaration replacing the traditional Self Assessment return.

That is six separate HMRC submissions per tax year, compared to four quarterly VAT returns. The quarter-end dates for income tax MTD do not align with standard VAT quarter dates. A sole trader managing both systems is managing two overlapping but non-synchronised submission calendars, two sets of deadlines, and two separate digital records obligations.

Why Your Free VAT Software Knows Nothing About Income Tax MTD

VAT return software is built around one technical integration: a connection to HMRC's VAT MTD API. That API accepts a nine-box VAT return, confirms submission, and issues a reference number. The software logs the record. That is the complete technical scope.

The HMRC MTD ITSA API is a different integration entirely. It handles income categorisation across trading and property types, expense categorisation using HMRC's specific categories for each income source, quarterly income and expense totals in a different data structure, and a two-stage year-end process that has no VAT equivalent. Building MTD ITSA support means integrating a fundamentally different product, not adding a feature to a VAT tool.

This is not a criticism of free VAT software. It is a description of what the category is designed to do. When a free VAT return tool shows you a confirmation screen after a successful submission, that confirmation is real and accurate within its scope: your VAT return has been received. HMRC's income tax system has not registered the transaction. The two systems do not communicate. Your income tax MTD obligations remain entirely unmet.

As HMRC Compatible Software: What the Label Cannot Tell You explains in detail, "MTD compatible" is not a universal status. It is specific to a named obligation. Software that is MTD-compatible for VAT is not MTD-compatible for income tax unless it explicitly says so and appears on HMRC's separate MTD ITSA-approved software register. These are different lists maintained by HMRC for different obligations.

The VAT Threshold and the MTD ITSA Threshold Are Not the Same Number

A source of confusion worth naming directly: the VAT registration threshold and the MTD for Income Tax threshold are different figures, and the relationship between them creates a specific category of under-prepared sole trader.

Businesses must register for VAT when taxable turnover exceeds £90,000 (the threshold since April 2024). They become liable for MTD ITSA when total self-employment and property income exceeds £50,000. These are different tests measuring different things.

A sole trader billing £60,000 a year is liable for MTD ITSA but not required to register for VAT unless their taxable turnover reaches £90,000. A VAT-registered sole trader billing £95,000 with high allowable costs might have net trading income closer to £55,000, still above the MTD ITSA threshold in most cases, but the point is that the two obligations are not triggered by the same figure.

The overlap zone is the problem zone: sole traders billing between £50,000 and £90,000 who have registered for VAT voluntarily, or who crossed the threshold at some point and remained registered, now face both systems simultaneously. Free VAT return software was designed for the VAT registration compliance problem. It predates MTD ITSA entirely and was not built to extend into income tax territory. Searching for the best free VAT return software in this situation returns tools that solve the smaller of the two problems.

The Sole Trader Who Does Not Know They Are Non-Compliant

The practical risk falls hardest on a specific type of sole trader: VAT-registered, earning between £50,000 and £90,000, filing quarterly VAT returns competently through software, and unaware that a parallel income tax compliance obligation has been running since April 2026.

Consider a self-employed plumber billing £68,000 a year. They registered for VAT when turnover crossed the threshold, adopted free software to comply with MTD for VAT in 2022, and have been filing quarterly returns without issue for three years. They have not received a specific enforcement notice from HMRC requiring MTD ITSA registration, because HMRC's communication on this obligation has been patchy and responsibility for registration sits with the taxpayer, not the software provider.

That plumber needed to register for MTD ITSA before the April 2026 start date, begin keeping digital income and expense records in a compatible format, and submit their first quarterly income tax update by 7 August 2026. That deadline has already passed.

HMRC's penalty system for MTD ITSA uses a points-based model: one penalty point per missed quarterly submission deadline. Accumulate four points and a £200 penalty is triggered, with further charges for each additional missed deadline thereafter. Points clear only after two complete years of full compliance from the date they were issued. Missing one deadline is recoverable. Arriving at the end of the first tax year with four missed quarterly updates and a missed end-of-period statement is materially more serious, and the route back to a clean compliance record is two years long.

The free VAT software diligently filing every VAT return on schedule has no mechanism to surface any of this. Its job is VAT. Income tax is not its job.

The Right Question to Ask Before Choosing Software

The search for the best free VAT return software returns valid results. For a sole trader whose only digital filing obligation is quarterly VAT returns, a free VAT tool is a reasonable solution and comparing the available options is a worthwhile task.

But the search becomes misleading for any sole trader who is both VAT-registered and earns over £50,000. That combination creates two simultaneous digital obligations, and the best free VAT return software addresses only one. The more useful search is: what software covers both my VAT MTD returns and my MTD Income Tax quarterly updates?

The answer to that question is a shorter and less competitive list. Few providers offer genuinely free coverage of both systems. Most treat income tax MTD functionality as a premium feature relative to the free VAT tier, with pricing that reflects the greater complexity of building and maintaining the MTD ITSA integration. Cheapest MTD Software: What Low Price Actually Buys You breaks down what the pricing tiers actually contain in practice.

Before committing to any free VAT tool, ask a single question: does this software also support MTD for Income Tax quarterly updates, the end-of-period statement, and the final declaration? If the answer is no, or if the product page does not mention MTD ITSA, the software solves one problem and leaves another unaddressed.

TapTax is built for the sole trader facing both obligations simultaneously. The VAT return workflow and the income tax MTD quarterly update workflow sit in the same interface, with one deadline view covering both systems. If your current free VAT software does not offer that, the comparison worth making is not between the free VAT tools. It is between what your current tool covers and what HMRC has required since April 2026.

The plumber who opened this argument is not in trouble because they chose bad VAT software. They are in trouble because they solved a 2022 compliance problem and trusted it remained the complete answer in 2026. That gap, between what the best free VAT return software does and what sole traders now legally owe HMRC, is four months old and already accumulating penalty points for anyone who has not noticed.
