Free VAT Software Handles Only One of Your HMRC Deadlines

Free VAT software does exist. HMRC's approved software list includes tools that cost nothing to use for straightforward VAT filing. But if you are a sole trader who typed that query into a search engine, you are probably asking a question that is already partly answered and partly the wrong question entirely.

Here is what is actually happening, and why it matters considerably more in 2026 than it did in 2022.

MTD for VAT: The Mandate That Already Arrived

Making Tax Digital did not start in 2026. HMRC rolled out its first digital filing mandate for VAT in April 2019, covering businesses with taxable turnover above £85,000. By April 2022, the requirement extended to every VAT-registered business, regardless of size. If you registered for VAT voluntarily to reclaim input tax, you were still caught.

Since that April 2022 deadline, every VAT return has had to be filed through MTD-compatible software. Paper returns and manual entry via the old HMRC portal are no longer accepted. This is not an upcoming rule. It is the law now.

Free VAT software, in this context, refers to tools approved by HMRC for MTD for VAT submissions that carry no subscription fee. Several exist. Most are what the industry calls bridging software: you record your VAT data in a spreadsheet, the bridging tool pulls the figures and submits to HMRC digitally. The bridge satisfies the technical requirement. The spreadsheet remains entirely your responsibility.

The Spreadsheet Problem Nobody Advertises

Free bridging software works. That is not the issue. The issue is that "works" and "is appropriate for your situation" are not the same claim.

If you are a sole trader with a handful of VAT-able invoices each quarter, a bridging tool that reads from a tidy spreadsheet is genuinely adequate. The tool submits your nine-box VAT return digitally. HMRC receives it. You pay or reclaim. Done.

The moment your record-keeping becomes complicated, that chain becomes fragile. Multiple income streams, mixed-rate supplies, purchase invoices with partial VAT recovery, subcontractor payments: any of these turns the spreadsheet from a convenience into a liability. A single formula error in the wrong cell submits an incorrect return. Bridging software does not validate your figures; it transmits them.

More significantly: bridging software is designed exclusively for VAT. It has nothing to say about Income Tax.

April 2026 Adds a Second Digital Mandate

Here is the part that search results for "free VAT software" tend not to mention.

From 6 April 2026, HMRC introduces Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) for sole traders and landlords with gross income above £50,000. This is a separate, additional requirement to VAT. Instead of a single annual Self Assessment return, you will submit four quarterly updates of income and expenses directly to HMRC, plus an end-of-period statement and a final declaration.

If you are a VAT-registered sole trader turning over £90,000 or more, you will, from April 2026, be required to make:

• Four VAT returns per year (already required since 2022)
• Four quarterly Income Tax updates per year (new requirement)
• One end-of-period statement (new)
• One final declaration (new)

That is ten separate HMRC submissions annually, compared to the five most VAT-registered sole traders handle today: four VAT returns and one Self Assessment.

The free VAT bridging software you found cannot help with any of the new Income Tax submissions. MTD for ITSA requires software that maintains digital records of income and expenses, calculates running tax estimates, and submits to a different set of HMRC APIs than those used for VAT.

Who Is Actually Caught by This?

Not every VAT-registered sole trader faces the April 2026 deadline immediately. The rollout is staged:

• April 2026: gross income above £50,000
• April 2027: gross income above £30,000
• April 2028: income above £20,000 (threshold and date subject to HMRC confirmation)

A sole trader who registered for VAT voluntarily at a turnover of £40,000 falls into the second cohort and has until April 2027 before MTD for ITSA applies. But they still need MTD-compatible VAT software now, and that software will need to eventually handle ITSA submissions too.

The typical profile of a sole trader searching for free VAT software is a tradesperson or freelancer who crossed the £90,000 registration threshold and is trying to manage quarterly compliance without paying for full accounting software. That person is almost certainly in the April 2026 cohort.

For them, the free bridging tool is a stopgap, not a solution. And the upgrade decision deferred today becomes a migration problem in eighteen months. As explored in Making Tax Digital Accounting Software: The Switching Cost Nobody Quotes, changing software mid-year means moving historical records, recategorising transactions, and re-learning a new interface under submission pressure.

What Free VAT Software Cannot Do

It is worth being precise about the limits, because software vendors are not always transparent about them.

No income tracking. Bridging software transmits your nine-box VAT figures. It does not know your income, your expenses, or your profit. For MTD for ITSA, you need software that captures every transaction as it happens, assigns it to an income or expense category, and maintains a running digital ledger.

No quarterly ITSA submissions. The APIs for MTD for VAT and MTD for ITSA are separate. A tool approved for the former is not automatically approved for the latter. HMRC Compatible Software: What the Label Cannot Tell You covers this in detail; the short version is that HMRC's approved software list is distinct for each mandate.

No tax estimates. One of the stated benefits of MTD for ITSA is that sole traders see running tax estimates throughout the year, helping them set aside the right amount rather than facing a surprise bill each January. Free bridging tools provide nothing of the kind.

No receipt capture. Paper receipts and manual data entry remain entirely your problem. For a sole trader with dozens of trade purchases each month, that is a significant administrative overhead that bridging software does not reduce.

The Real Cost of the Free Option

There is a pattern worth naming directly. HMRC mandated digital VAT filing in 2022. It did not build a free, fully-featured tool to replace the manual filing portal it was closing. Instead, it published an approved software list and left the market to set prices.

The result: free options exist but carry limitations that push most businesses with any complexity toward paid software eventually. Free Accounting Software UK: The Data Question HMRC Ignores examines what the market does with your financial data when the software costs nothing. That question applies equally to VAT software.

The same pattern is repeating for MTD for ITSA. HMRC is not building a free tool for sole traders. It is publishing another approved software list and leaving pricing to vendors. The bridging tools that serve the VAT market may extend to ITSA submissions in name, but full-featured ITSA software, with income tracking, expense categorisation, and running tax estimates, is commercially priced.

For a sole trader accustomed to paying nothing for VAT bridging, the first subscription invoice from an ITSA-capable tool arrives as an unwelcome surprise. The upgrade path from free VAT software to a full MTD-compliant accounting package is not signposted in advance. It rarely is. Free MTD Software: The Mid-Year Upgrade Trap documents exactly how that transition tends to unfold.

What to Actually Look For

If you are VAT-registered and earning above £50,000, the practical question is not "is there free VAT software?" but "what do I need to be compliant from April 2026, and what will it cost?"

The checklist is short:

1. MTD for VAT: already required. Your current software handles this. If it is free bridging software, that is adequate for now.
2. MTD for ITSA: required from April 2026. You need software separately approved for ITSA submissions, not just VAT.
3. Digital record-keeping for income and expenses. Not a spreadsheet you update monthly; a running digital record that captures transactions as they happen.
4. Integration. Ideally, one tool handles both VAT and ITSA. Running two separate software subscriptions doubles cost, doubles the risk of error, and complicates year-end reconciliation.

Tools designed specifically for sole traders, rather than adapted from SME accounting packages, tend to be simpler and cheaper for this use case. Best Sole Trader Accounting Software UK: Follow the Money covers how to evaluate options without being sold features you will never use.

The Submission Maths, Made Concrete

A self-employed electrician turning over £95,000 faces the following from April 2026:

• Quarterly VAT return, due in April, July, October, and January
• Quarterly ITSA income and expense update, in the same calendar quarters, as a separate submission
• End-of-period statement at year end
• Final declaration at year end

Ten submissions. Free VAT bridging software handles four of them. The remaining six require a different tool entirely.

The penalty structure for missed MTD for ITSA submissions uses a points-based system: each missed quarterly update earns one point, and four points triggers a £200 penalty. Each subsequent late submission after reaching that threshold adds a further £200. For a business already managing quarterly VAT compliance, adding a second quarterly cycle is not administrative background noise; it is a material compliance burden with real financial consequences.

The free VAT software search is understandable, and the tools it surfaces are real. But for most VAT-registered sole traders who will be caught by MTD for ITSA in April 2026, free VAT software solves only the easier half of the problem. The harder half arrives in eighteen months, and no bridging tool will bridge that gap.
