Best Free MTD Software for VAT Exists. Here Is the Catch.

If you have spent an afternoon searching for the best free MTD software for VAT, you will have noticed something peculiar: HMRC maintains a list of over 200 approved software products for Making Tax Digital, yet the overwhelming majority are paid subscriptions. The question nobody asks is why, and what the genuinely free route actually looks like.

The answer involves bridging software, a category of tool that HMRC quietly sanctions but that the major accounting software vendors have every commercial incentive to ensure you never hear about.

What HMRC Actually Approved (and Why Most of It Costs Money)

HMRC's recognised software list for Making Tax Digital for VAT runs to more than 200 products. The list includes household names: Xero, QuickBooks, Sage, FreeAgent, all starting at roughly £12 per month and climbing sharply from there. Scroll past the large marketing budgets and you will find a quieter category, one that rarely features in roundup articles or sponsored comparison tables: bridging software.

HMRC defines bridging software as a tool that takes data from an existing digital source, usually a spreadsheet, and submits it directly to HMRC's API. It does not replace your accounting. It does not categorise your transactions or flag unusual expenses. It does one thing: it reads cells in your spreadsheet and files your VAT return to HMRC.

This distinction matters enormously when you are searching for free MTD software for VAT, because bridging software is where the genuinely free or near-free options actually live.

The Free Options That Actually Exist

Let us be specific, because most comparisons in this space are not.

Portico by FreeAgent is a standalone, free web application for MTD VAT submissions. FreeAgent built it to serve businesses that want MTD compliance without committing to a full accounting subscription. No sign-up to FreeAgent's paid product is required, and there is no usage limit on standard quarterly submissions. FreeAgent's commercial hope is that you eventually upgrade, but the product itself is functional and costs nothing for the majority of sole traders filing standard quarterly returns.

VitalTax offers a browser-based free tier for MTD VAT. You enter your nine VAT box figures directly into the interface, and VitalTax handles the HMRC API connection on your behalf. The free tier covers standard rate VAT returns; flat rate scheme users need a paid plan. For a sole trader on the standard scheme filing quarterly, this is a workable zero-cost option with a straightforward interface.

DataDear is an Excel add-in that connects your spreadsheet directly to HMRC's API. Its personal free tier allows one submission per month, which is sufficient for quarterly filers. If your records already live in Excel, DataDear is the closest thing to a genuinely integrated free bridging solution: no separate data entry required.

ANNA Money includes free MTD VAT submissions as part of its business current account. If you already bank with ANNA, VAT filing is included at no extra charge. The catch: you need to use their banking product, which makes this a benefit rather than a standalone software choice.

Why Vendors Never Lead with the Bridging Option

Here is the conflict of interest that nobody in the MTD software industry discloses.

Xero reported revenues of NZD $1.66 billion in its 2024 financial year. QuickBooks owner Intuit reported $16.1 billion in the same period. Sage, listed on the London Stock Exchange, posted revenues of £2.18 billion. A meaningful portion of those revenues comes from small business subscriptions that exist, in the UK, because HMRC mandated digital record-keeping without building a free tool to handle it.

When HMRC shut the free VAT portal in April 2022, as covered in Free VAT Filing Software: The Portal HMRC Closed in 2022, it handed the compliance market to private vendors. A compliance obligation that had been free to discharge became a recurring monthly cost for hundreds of thousands of VAT-registered businesses. The government's position was that the private sector would deliver better software; the private sector's position was that it would deliver software at a price.

Bridging software disrupts that model. A sole trader who keeps records in Google Sheets and submits VAT via Portico is technically MTD compliant at zero monthly cost. That sole trader is also a lost customer for every accounting software vendor running sponsored adverts in your search results.

The consequence is predictable. Bridging software rarely features in best-of lists. It is buried in comparison tables, if it appears at all. It is almost never mentioned in the promotional emails that arrive before a VAT return deadline. The vendors who profit most from MTD compliance have a structural incentive to ensure the free route is not the first thing you discover.

This is not a conspiracy. It is advertising economics. But it is worth naming, because it explains why you are reading about bridging software here rather than on the homepage of any major accounting software provider.

What Bridging Software Actually Demands of You

Free MTD VAT compliance through bridging software is real. What it asks in return for its zero price tag deserves honest examination.

You are the accountant. Bridging software does not categorise your transactions, flag mismatched figures, or warn you when something looks wrong. It submits whatever you give it. A carpenter who has maintained the same consistent spreadsheet for four years will find this arrangement familiar. A sole trader switching from a cloud accounting package will find the absence of error-checking disorienting and potentially expensive.

You maintain the digital link. MTD for VAT requires an unbroken digital link between your source transaction records and your submission to HMRC. That means you cannot manually retype figures from one document into another; HMRC considers that a break in the required chain. If you use bridging software, your spreadsheet must be structured so that VAT figures flow automatically from your transaction records into the cells the bridging tool reads. This is a one-time setup task, but it requires care and a basic understanding of spreadsheet formulas.

Errors are your responsibility. Full accounting software catches obvious data entry mistakes, duplicate entries, and arithmetic inconsistencies. Bridging software does not. HMRC will process whatever you submit, including a return containing a transposed digit that overstates your output tax by £3,000. The cost of correcting a material error, through amended returns and potentially an accountant, can quickly exceed years of accounting software subscription fees.

Support is minimal. Free tiers typically offer limited customer service. If HMRC's API returns an unfamiliar error code during submission, or if the bridging tool fails to connect during the filing window, you are largely resolving it yourself or engaging an accountant at short notice.

Consider a self-employed electrician with a turnover of £115,000 who switched from a paid accounting package to free bridging software to cut costs. The first three quarters ran smoothly. In the fourth quarter, a structural change to the spreadsheet broke the digital link, and the tool submitted zeros across several VAT boxes. HMRC raised a compliance check. The accountant's fees to resolve it exceeded three years of the subscription the electrician had cancelled.

These are not reasons to avoid bridging software. They are reasons to understand precisely what free MTD VAT software does before you depend on it.

The Second Deadline That Nobody Mentions

If you are a VAT-registered sole trader with income above £50,000, free bridging software is solving exactly one of your two upcoming HMRC compliance problems.

MTD Income Tax Self Assessment becomes mandatory for sole traders with qualifying income above £50,000 from April 2026, dropping to £30,000 the following April. VAT-registered sole traders above those thresholds will need separate MTD-compliant software for income tax alongside their VAT tool. The quarterly update requirements for MTD ITSA are structurally different from VAT returns, and no current free bridging solution covers both obligations.

Free VAT Software Handles Only One of Your HMRC Deadlines examines this gap in detail. The short version: setting up free bridging for VAT today is not a complete compliance solution if your income puts you above the ITSA threshold. You are deferring a software decision, not eliminating it.

How to Choose Between Free Bridging and Paid Software

The decision reduces to three questions.

Are you confident in your own record-keeping? If you have maintained a clean, consistent spreadsheet for more than a year and you understand exactly how your figures flow from invoices and receipts to VAT boxes, bridging software is a legitimate option. If your records are patchy, maintained informally, or you rely on accounting software to impose discipline on your bookkeeping habits, the absence of error-checking in bridging software is a genuine risk rather than a minor inconvenience.

What is your income trajectory? If you are already above £50,000 and likely to remain there, you will need MTD ITSA software by April 2026 regardless of what you use for VAT today. The combined cost of a free VAT bridging solution and a separate ITSA subscription added in 2026 may well exceed the annual cost of a combined MTD platform chosen now. Best Accounting Software for Making Tax Digital: The Exit Test covers how to evaluate whether a combined solution is worth it before you are locked in to two separate tools.

What is your time worth? Xero's Starter plan costs approximately £144 per year. If bridging software saves you £144 but costs you three additional hours of spreadsheet maintenance annually, and your effective day rate is above £48 per hour, you have not saved money. You have moved the cost from your bank account to your diary, which is a legitimate choice but not a free one.

The Straight Answer

The best free MTD software for VAT is Portico by FreeAgent for most sole traders filing standard quarterly returns. It is genuinely free, HMRC-recognised, and requires no banking relationship or paid subscription to use. VitalTax is the better option if you want to enter VAT figures directly without connecting a spreadsheet. DataDear suits anyone already committed to Excel as their core bookkeeping platform.

None of these tools will tell you your figures are wrong. None will remind you your return is due. None will prepare you for the MTD Income Tax obligation that arrives in April 2026 and that the search phrase "best free MTD software for VAT" entirely fails to surface.

That is the catch promised at the outset. Free MTD VAT software exists, it is HMRC-approved, and it may be exactly right for your situation. But if your income is above £50,000 and April 2026 is on your horizon, the search that brought you here was asking only half the right question.
