Free MTD Software: The Questions Nobody Asks Before Signing Up

April 2026 is close enough that "I'll sort it later" is no longer a safe answer. If you're a sole trader turning over more than £50,000, Making Tax Digital for Income Tax is no longer optional, and the scramble to find free MTD software that actually works has already begun.

But here's the question almost nobody asks before they click download: free compared to what, exactly?

Why the Free Question Keeps Coming Up

Search for free MTD software and you will find no shortage of results. What you will find much harder to locate is a straight answer about what free actually means in each case.

This is not an accident. The software market around Making Tax Digital has been shaped by a simple commercial reality: HMRC mandated that sole traders above the income threshold must use third-party software, but HMRC chose not to build a free tool itself. That decision, confirmed in 2022 and quietly maintained since, created a guaranteed customer base of hundreds of thousands of self-employed people who must buy a commercial product to comply with the law.

In that environment, free tiers are not acts of generosity. They are customer acquisition strategies. Understanding that is the first step to asking better questions.

The Five Questions That Sort Good Free From Bad Free

1. Is it free for MTD submissions, or just for bookkeeping?

This distinction trips up more sole traders than any other. Several well-known accounting platforms advertise free plans that cover expense tracking, invoicing, and basic profit and loss reports. What they do not always include is the ability to submit quarterly updates to HMRC under MTD for Income Tax.

When April 2026 arrives, you need software that can connect to HMRC's API and transmit your quarterly figures. If the free tier only handles the bookkeeping side and locks MTD submission behind a paywall, then you are not looking at free MTD software. You are looking at free bookkeeping software with a paid MTD add-on.

Before you invest a single hour categorising expenses in any platform, confirm in writing, or at minimum in their published pricing page, that quarterly MTD submissions are included in the free tier. Do not assume. Check.

2. Is there an income cap on the free plan?

Several platforms that genuinely offer MTD functionality at no cost apply an annual income ceiling to free users. Common thresholds are £20,000, £30,000, or occasionally £50,000 in self-employment income.

This creates a specific problem for the sole traders who most urgently need MTD compliance: those earning above £50,000, who will be mandated first, are often the same people who exceed the income limits on free software tiers. In other words, the people who need it most are precisely the ones who cannot have it for free.

If you are turning over between £50,000 and £80,000 as a plumber, electrician, or independent contractor, run that income figure against the free tier limits of any software you are considering. The answer may surprise you.

3. What happens to your data if you downgrade or leave?

This question rarely appears in comparison articles, but it is arguably the most important one for long-term planning. Your MTD records are not just a compliance convenience. HMRC can investigate your tax affairs going back four years in standard cases, and up to six years if they believe there has been careless conduct.

If a free MTD software provider changes its terms, gets acquired, or folds entirely, what happens to the quarterly submission records you have stored with them? Can you export them in a usable format? Is that export free, or does it require a paid tier to access?

Some platforms lock historical data behind paid plans. Others provide full exports in CSV or PDF format on request. A few, particularly smaller players, have unclear data retention policies altogether. Read the terms of service before you upload a single receipt, not after.

4. Is the free tier genuinely sustainable, or is this a promotion?

Software companies do not survive on goodwill. If a platform is offering full MTD compliance functionality at no cost indefinitely, the legitimate question is: how are they paying for server costs, API maintenance, HMRC compliance updates, and customer support?

The honest answers are usually one of three things. First, the free tier is a stripped-back loss leader designed to convert users to paid plans. Second, the company is venture-backed and burning investor money to acquire users ahead of a monetisation shift. Third, the free tier is genuinely limited enough in scope that it costs very little to maintain.

None of these is automatically bad. But all of them carry risk. A venture-backed startup that runs out of runway may pivot its pricing overnight. A loss leader may tighten its free tier once user numbers plateau. A genuinely limited free product may not cover your needs as your business grows.

Ask yourself: if this company raised its prices tomorrow, what would your options be? If the answer is "start again from scratch with a new platform," that is a meaningful hidden cost of the free tier.

5. What does setup actually require?

Free does not mean fast. Some MTD software platforms advertise a frictionless sign-up but then require you to connect your bank account, import historical transactions, categorise months of past income, and verify your Government Gateway credentials before you can submit a single figure to HMRC.

For a sole trader who earns their living on site rather than behind a screen, this kind of setup overhead is not a minor inconvenience. It is a real barrier. If you spend three hours configuring software that costs nothing in cash, you have still paid three hours of your time, which at £50,000 annual income works out to roughly £24 per hour using a standard working year calculation.

Free MTD software that takes four hours to set up has already cost you around £96 before you have filed a single quarterly update.

The better question is not "is it free?" but "is it quick, and does it stay that way?"

What the Approved List Does and Does Not Tell You

HMRC publishes a list of software compatible with MTD for Income Tax. As of mid-2025, the list includes both free and paid options, though the balance skews heavily towards paid products. HMRC's criteria for inclusion are technical: the software must be able to connect to the MTD API and submit the required data in the correct format. HMRC does not evaluate value for money, ease of use, data security practices beyond the minimum, or whether free tiers are genuinely free.

Being on the approved list means a product can talk to HMRC. It does not mean it is the right product for you.

This is a point worth sitting with. The approved list exists to confirm technical compatibility, not to serve as a consumer recommendation. HMRC Making Tax Digital Software: The Compatibility Test explains in detail what that compatibility actually covers and what it leaves out.

The Bridging Software Route: A Note

Some sole traders ask whether they can use a spreadsheet and a bridging tool to satisfy MTD requirements without buying dedicated accounting software. The answer is technically yes, but with conditions.

Bridging software connects your spreadsheet to HMRC's API and transmits the quarterly figures. The spreadsheet itself must maintain digital records that meet HMRC's requirements, meaning no hybrid paper-and-digital systems. And the bridging software itself is usually not free: most bridging tools charge between £8 and £25 per month, which for a sole trader making five submissions per year is arguably more expensive per submission than a straightforward MTD app.

The bridging route suits those who already maintain detailed spreadsheet records and have the confidence to ensure those records are MTD-compliant. It is not a shortcut for people who currently track income in a notebook or a basic notes app.

What to Look for Instead of Free

The better framing for most sole traders is not "what is free?" but "what is the lowest total cost of compliance over three years, including setup time and the risk of switching?"

On that basis, a product that charges £5 to £10 per month but takes 20 minutes to set up and 15 minutes per quarter to operate may represent better value than a nominally free tool that takes four hours to configure and requires a degree of bookkeeping knowledge to use without errors.

This is especially true once you factor in the penalty structure HMRC is introducing alongside MTD. Late or missing quarterly submissions will attract points under a new penalty regime, with cash fines triggered once you accumulate enough points. A single late filing could cost you £200. Four late filings in a year could cost significantly more. The cost of getting it wrong is not abstract.

Making Tax Digital for Income Tax: The Five Submission Problem breaks down exactly what you are required to submit and when, which is useful context when evaluating whether any software makes those submissions simple enough that you will actually do them on time.

Where TapTax Sits in This Picture

TapTax is built for sole traders who want to be MTD-compliant without becoming part-time bookkeepers. The design logic is simple: you record income and expenses as you go, TapTax handles the categorisation, and when a quarterly deadline arrives, the submission to HMRC takes minutes rather than hours.

There are no accountant-level menus, no features you will never use, and no model built around converting you from a free tier to an expensive one. If you are looking for software that is honest about what it costs and straightforward about what it does, TapTax is worth a look before you tie yourself to a platform with more small print than features.

For a broader view of how to evaluate any MTD software, including the questions you should ask before committing, Best Making Tax Digital Software: Tried, Tested, Brutal applies a similar rigour across a wider set of products.

The Only Free MTD Software Worth Having

Free MTD software is worth having if it genuinely covers quarterly submissions at no cost, imposes no income limit that excludes you, gives you clean data export rights, and has a business model you can understand. Those four conditions eliminate a significant portion of what is marketed as free.

If you started reading this post asking which free tool to download, the more useful question to leave with is this: which tool will still be free, still be supported, and still be approved by HMRC when your first quarterly deadline arrives in August 2026? If you cannot answer that confidently about the product you are considering, the word "free" is doing a lot of work it may not be able to sustain.

The deadline is real. The penalties are real. The software decision is worth twenty minutes of proper thought, not just a quick click on whatever appears first in a search result.
