HMRC MTD Software: How the Approved List Actually Works

April 2026 is closer than it feels, and HMRC's approved software list has quietly become one of the most consequential documents in UK self-employment. If your income exceeds £50,000, you need software on that list. If it exceeds £30,000, you will by April 2027. The list exists. What it tells you, and more importantly what it withholds, is another matter entirely.

What the HMRC Approved List Actually Tests

HMRC publishes a list of software compatible with Making Tax Digital for Income Tax (MTD ITSA). Vendors appear on it after demonstrating that their product can send and receive data through HMRC's Application Programming Interface (API). That is the entire test. It is a technical handshake, not a quality stamp.

Think of it like a restaurant passing its hygiene inspection. A score of five stars means the kitchen is sanitary. It says nothing about whether the food is any good or whether the bill is reasonable. HMRC's approved list works the same way. A product with a three-star Trustpilot score and a £40-per-month price tag sits alongside genuinely useful, affordable tools, and the list makes no distinction between them.

As of mid-2025, HMRC's compatibility list contains dozens of products. They range from enterprise accounting suites aimed at firms with accountants on staff, to lightweight apps aimed squarely at sole traders logging invoices from a van. The badge looks the same on all of them.

Why HMRC Outsourced This to the Private Sector

The question most sole traders never think to ask is: why does approved HMRC MTD software have to be third-party at all? HMRC already collects your data, holds your records, and runs the digital infrastructure that all this software connects to. Building a basic free submission tool would be, by any reasonable estimate, straightforward.

The answer is part policy choice, part lobbying history. When MTD was first designed under the 2017 Making Tax Digital roadmap, HMRC made an explicit decision not to build its own software. The official reasoning was that the private sector could deliver better products faster. The unofficial reading, documented in the 2020 House of Lords Economic Affairs Committee report on MTD, is that software vendors had a strong commercial interest in that outcome and the lobbying infrastructure to pursue it.

The result is a market where sole traders are legally required to use a paid product to comply with a government mandate. That is not inherently scandalous, but it is worth naming clearly. We explored the full commercial picture in Best MTD Software: Why Complexity Is the Business Model if you want the longer version.

How to Read the Approved List Without Being Misled

When you visit HMRC's MTD software page, you will find filters for business type, tax type, and whether the product is free. That last filter is worth pausing on. "Free" on HMRC's list means free to some users under some conditions. It does not mean free for everyone at every income level.

Several products listed as free are free only for a single user, for a trial period, or for a stripped-back tier that does not include quarterly submissions. We documented exactly how this plays out in Best Free Making Tax Digital Software: The Fine Print Test. The short version: read the pricing page before you read the feature list.

Here is what the approved list does not tell you:

Whether the product suits sole traders specifically

Most approved MTD software was built for limited companies or accountancy practices first, with a sole trader mode bolted on later. That matters because a plumber tracking materials and mileage has fundamentally different needs from a small limited company managing payroll and VAT returns. Software built for the latter will almost always feel clunky for the former, regardless of what the marketing says.

Whether the price is stable

Several products on the approved list have raised prices significantly since MTD deadlines were confirmed. Approval status does not lock in pricing, and there is no regulatory mechanism preventing a vendor from doubling its subscription cost the year MTD becomes mandatory.

Whether support is any good

HMRC's approval process involves no customer support assessment. A product can pass the API test and still leave you waiting four days for an answer when you cannot reconcile a bank feed in January, which is the worst possible time to have a technical problem.

The Five Things a Sole Trader Should Actually Check

Once you have confirmed a product appears on HMRC's approved list, here is the real due diligence:

1. Is quarterly submission included in the base price? Some products charge extra for MTD-specific features on top of the standard subscription. Check that the tier you are being quoted actually enables all four quarterly updates and the final declaration, not just basic record-keeping.

2. Is bank feed connection included, or is it an add-on? Connecting your bank account to automatically import transactions is the single biggest time-saver in any MTD workflow. If it is locked behind a higher tier, the advertised price is not your real price.

3. How does the product handle the cash basis? Most sole traders use cash basis accounting, which means you record income when it is received and expenses when they are paid, not when invoices are raised. Some software defaults to accruals accounting and requires manual adjustment. This is a surprisingly common source of errors on quarterly submissions.

4. What happens if you want to leave? Data portability is the question vendors hate. If you decide to switch approved software midway through a tax year, can you export your records in a format another product will accept? The MTD Software for Sole Traders: Switching Without the Chaos post covers this in detail.

5. Is the pricing transparent one year from now? Check whether the product offers annual pricing and whether any introductory rate applies. A £4-per-month introductory offer that becomes £18 after six months is a common pattern in this space.

The Approval Process Does Not Protect You From Bad Software

It is worth sitting with this for a moment, because the branding around "HMRC-approved" or "HMRC-recognised" software is doing a lot of work it is not entitled to do. HMRC's own guidance states clearly that appearing on the list does not constitute an endorsement of the product or its features.

That distinction matters when you are a self-employed electrician who has spent two hours trying to categorise a batch of tool receipts and the software has frozen twice. The HMRC badge on the vendor's homepage does not mean anyone at HMRC has ever used the product under real-world conditions.

The Software for Making Tax Digital: The Setup Trap Nobody Warns You About post covers what happens when approved software fails in practice. The setup stage, in particular, is where most sole traders hit problems that the approval badge gave them no reason to anticipate.

Where TapTax Fits Into All of This

TapTax is on HMRC's approved list. But more relevantly for a sole trader, it was built specifically for the way sole traders actually work, not adapted from an accountancy practice tool. Quarterly submissions, bank feed connections, and expense categorisation are in the base product. There is no enterprise tier you are accidentally paying for.

For a sole trader earning £50,000 to £80,000, the practical question is never just "is this software approved?" It is: will this save me time four times a year without requiring a degree in accountancy to operate? The approved list cannot answer that. Your trial period can.

If you are still working out whether the figures stack up for your income level, the TapTax tax calculator is a useful starting point before you commit to any software subscription.

The Honest Summary

HMRC's approved MTD software list is a necessary starting point, not a finishing line. It tells you a product can technically connect to HMRC's systems. It tells you nothing about whether that product is worth your money, whether it will be easy to use at 9pm after a full day on site, or whether the price you see today will be the price you pay in eighteen months.

The search for the right HMRC MTD software comes down to three real questions: Does the base price include everything you need for quarterly compliance? Does it work the way a sole trader thinks, not the way an accountant does? And can you get out of it without losing your data if the answer to either of those turns out to be no?

April 2026 opened this piece. That date has not changed. The approved list will not make the decision for you, but at least now you know what it actually means.
