MTD-compatible Accounting Software: One Test, 200 Products

HMRC's list of recognised accounting software for Making Tax Digital contains, at the time of writing, well over 200 entries. The government's guidance on how to choose between them amounts, in practice, to the instruction to pick one.

There is a word buried in that list doing a lot of quiet work. Recognised. It is the word sole traders searching for compliant software latch onto, because it implies HMRC has looked at these products and found them acceptable. It implies a standard beyond the technical. It implies, in short, that you can trust the list to guide your decision.

It cannot. Here is what MTD-compatible accounting software actually means, and how to find a product that genuinely suits your situation as a sole trader preparing for Making Tax Digital for Income Tax, which becomes mandatory for incomes over £50,000 from April 2026.

The Recognition Process Is an API Test, Nothing More

To appear on HMRC's recognised software list, a vendor must demonstrate that their product can communicate with HMRC's MTD API. Specifically, the software must be able to submit quarterly income and expenditure summaries, retrieve obligations (the schedule of what is due and when), and produce an End of Period Statement that closes out a tax year.

That is the bar. Pass the API integration tests and you are on the list. HMRC does not assess:

• Whether the software is easy to use for a sole trader with no accounting training
• Whether it is priced fairly for someone earning £55,000 a year as a self-employed electrician
• Whether the vendor has adequate customer support
• Whether the company will still exist in three years
• Whether the software handles your specific business structure without workarounds

Recognition is a technical credential, not a consumer endorsement. HMRC is confirming that the software's plumbing works. It is not recommending that anyone turn on the tap.

The List Has Filters, But They Do Not Help Enough

HMRC does provide some filters on their software finder. You can narrow by business type (sole trader, landlord), by operating system (desktop, browser, mobile), and by whether you want a free option. So the characterisation of 200 products with zero guidance is slightly unfair; it is more accurate to say there are dozens of products after filtering, still with zero guidance on which one is right for you.

Filter by sole trader and free and you get a list of products with entirely different approaches to what free means. Some are free for a trial period. Some are free for VAT submissions only. Some are free at a basic tier that does not actually cover everything MTD for Income Tax requires. The full cost of nominally free MTD software is a topic the list will never address, because HMRC does not check pricing at all.

Filter by sole trader and paid and the range is equally bewildering. Monthly costs span from under £5 to over £40 for what are, in practical terms, very similar sets of MTD functionality. The price difference largely reflects whether you are paying for bookkeeping, invoicing, payroll, and accountancy features you will never use as a sole trader who just needs quarterly submissions handled.

Sole Trader Software Hides Three Products. You Need One. covers this bundling problem in detail. The short version: most recognised MTD software was built for small businesses with employees, and it shows in the interface, the pricing tiers, and the features that take prominence in the onboarding flow.

The Minimum Viable Product Problem

Software vendors are rational actors. To achieve HMRC recognition, they need to pass the API tests. They do not need to build software that a plumber with no accounting training finds intuitive. They do not need to build software that correctly categorises a mix of materials costs, subcontractor payments, and mileage claims without manual intervention.

They need to pass the tests. Once they have, the recognition label persists regardless of what happens to the product's usability, pricing, or support quality, at least until they fall out of compliance with a future API update.

This is not a criticism of any specific vendor. It is a structural observation about what HMRC's recognition process incentivises. The minimum viable product for recognition is a technically compliant integration. Everything beyond that is optional. The consequence for sole traders is that some recognised apps were simply not built with MTD for Income Tax in mind at all. They were built as general accounting tools and MTD functionality was added later to maintain the credential.

Five Things Recognition Does Not Verify

Before treating any MTD-compatible accounting software as vetted for your needs, consider the five questions the list simply cannot answer.

1. Will it still be recognised when you need it?

HMRC's API evolves. Software that passes today's tests must keep pace with future API changes. Smaller vendors have historically struggled to maintain compliance as HMRC updates its specifications. If your software drops off the recognised list mid-year, you have a compliance problem with no quick fix. Checking a vendor's track record of maintaining recognition, not just having it, is worth the extra five minutes of research before you sign up.

2. Does it handle your income structure?

A sole trader with one income stream and straightforward expenses is in a different position to a freelance consultant who also earns rental income, or a tradesperson who operates a van, claims mileage, and invoices both trade customers and consumers. Some recognised software handles multiple income streams within a single quarterly submission. Others require you to manage them separately, or do not support them at all. HMRC's list does not filter by income complexity.

3. What happens at year-end?

MTD for Income Tax requires quarterly submissions throughout the year and a final End of Period Statement at year-end, followed by a tax calculation. Some recognised software handles all of these within a single interface. Others cover quarterly submissions but require additional tools or manual steps for the year-end process. This is not a small distinction: getting the quarterly submissions right but fumbling the End of Period Statement creates exactly the compliance exposure you were trying to avoid by going digital in the first place.

4. Who supports you when something goes wrong?

HMRC's recognition process does not assess customer support. A product can be fully recognised and have support that consists entirely of a help centre article from 2023 and a chatbot that cannot answer questions specific to your business. For a sole trader filing their first set of quarterly returns, the quality of that support is not a nice-to-have. It is the difference between a ten-minute fix and a panicked afternoon.

5. What does it actually cost over three years?

Month-one pricing is not the number that matters. The year-two trap for accounting software is well-documented: introductory pricing expires, tier upgrades become necessary, and the friction of switching to a different recognised product (migrating historical records, relearning the interface, re-exporting your data) acts as a retention mechanism regardless of whether the price increase was justified. Check what the product cost twelve months ago before committing to what it costs today.

How to Actually Evaluate from the List

If you are working through HMRC's recognised software list yourself, here is a more useful framework than simply confirming a product appears on it.

Start with the End of Period Statement. Filter for products that explicitly support quarterly submissions and End of Period Statements for sole traders. This eliminates a meaningful portion of the list immediately, and the remaining products are at least covering the full MTD for Income Tax workflow.

Check the free tier with the pricing page, not the marketing page. If a product is listed as free on HMRC's site, find the vendor's pricing page independently and identify exactly which features sit behind a paywall. If the free tier does not cover End of Period Statements or annual tax calculations, it is not fully free for MTD purposes.

Look for a publicly available pricing history. Products that have changed their pricing significantly in the past two years will likely do so again. Checking archived versions of vendor pricing pages via tools like the Wayback Machine tells you far more than the current headline rate.

Test with your actual income type and expense categories. Most recognised software offers a trial period. Use it to set up your real business structure, your real categories of income and expenses, and one real quarter's worth of transactions. If the product forces workarounds at the trial stage, when you have time to figure them out, it will force the same workarounds when the filing deadline is two days away.

Ask a direct question to support before buying. Send the vendor's support team a question specific to your situation: how to handle a mix of labour and materials income, for instance, or how to log a personal vehicle used partly for business. Response time and accuracy tell you more about long-term product quality than any feature comparison table.

The Sole Trader's Shortcut

The MTD-compatible accounting software list was built for a procurement context: large organisations with IT departments who needed a compliance register, not sole traders who need to know whether a product is worth £9 a month and forty-five minutes of their time every quarter.

For a sole trader in the £50,000 to £80,000 income range preparing for April 2026, the list is a starting point, not a decision. Recognition tells you the technical minimum has been met. Everything that actually affects your experience, your wallet, and your compliance confidence sits outside the recognition criteria entirely.

TapTax appears on HMRC's recognised software list because it passes the API tests. The choice to build specifically for sole traders who want quarterly submissions handled without learning double-entry bookkeeping is a separate decision. The exit test for any MTD software is whether you can leave it if it stops serving you; that starts with not getting locked into a bundled suite you never needed in the first place.

If you want to see how a sole-trader-first approach to MTD works in practice, TapTax's free trial takes less time to set up than reading the full MTD-compatible software list from top to bottom.

What Recognised Really Means for April 2026

MTD-compatible accounting software is a defined, specific thing: software that passed HMRC's MTD API tests. That is a necessary condition for compliance, but it is nowhere close to a sufficient condition for a good experience or a fair price.

The word recognised carries weight it was never designed to carry. Sole traders searching for reassurance in that label are, understandably, hoping someone in authority has done the evaluation work for them. HMRC has not done that work, and the list reflects it faithfully.

Use HMRC's recognised software list to build your shortlist. Then evaluate against the five criteria above. The list gets you to the starting line. Your workflow, your income structure, and your tolerance for admin complexity determine which product actually crosses it.
