Free MTD Software UK: What Exists and What It Costs You
Searching for free MTD software in the UK? Here's what HMRC actually offers, what the 'free' tools hide, and what sole traders genuinely need.
Is there genuinely free MTD software in the UK, or is 'free' just a price tag that gets moved to the small print? If you have spent any time searching for Making Tax Digital tools, you will have noticed that the answer is murkier than HMRC's own guidance suggests.
- HMRC does not offer its own free MTD for Income Tax software, despite doing so for VAT.
- Several vendors advertise free MTD tiers, but most restrict the features that sole traders actually need.
- The real cost of 'free' software is often your time, your data, or an unexpected upgrade charge before your first quarterly deadline.
- Low-cost paid options designed for sole traders can work out cheaper than the hidden friction of free tools.
- TapTax offers straightforward MTD compliance pricing without burying the quarterly submission feature behind a paywall.
Let us be precise about what we are talking about. From April 2026, sole traders and landlords earning above £50,000 must use Making Tax Digital for Income Tax. Those earning above £30,000 follow in April 2027. That means finding compatible software is not optional; it is a legal requirement. And the question of whether any of it is free matters enormously when you are a plumber turning over £55,000 a year and already handing HMRC a significant slice of that.
- MTD for Income Tax Self Assessment (MTD ITSA)
- HMRC's mandatory scheme requiring sole traders and landlords above the income threshold to keep digital records and submit quarterly updates to HMRC using approved third-party software, replacing the annual Self Assessment return.
What HMRC Actually Provides for Free
Here is the uncomfortable truth: HMRC built free software for MTD for VAT. Millions of small businesses used it. When MTD for Income Tax came along, HMRC quietly decided not to build an equivalent. The department's own guidance directs sole traders to a list of third-party commercial vendors instead.
A 2023 investigation by the Public Accounts Committee found that HMRC had consistently underestimated the compliance burden on small businesses. Meanwhile, the software industry, which lobbied hard during the MTD consultation process, has benefited directly from a government mandate that effectively sends 4.2 million sole traders toward paid products.
For a deeper look at who profits from that arrangement, Who Really Profits From Making Tax Digital Software Costs? covers the political economy in detail.
What HMRC does offer, at no cost, is a free-to-use bridging tool for some VAT filers. There is no equivalent for Income Tax. The closest thing is a handful of software vendors on the approved list that offer a limited free tier.
The Free MTD Software That Actually Exists
HMRC maintains a list of software that has passed its compatibility testing. Within that list, a small number of products advertise a free tier. Here is an honest assessment of what those tiers typically include and exclude.
Spreadsheet Bridging Tools
Some vendors offer free or very cheap bridging software, which connects a spreadsheet you maintain yourself to HMRC's API and submits the figures. If you already keep meticulous records in Excel or Google Sheets and understand double-entry bookkeeping well enough to structure them correctly, this can work.
The catch: MTD requires digital records to be linked end-to-end. You cannot manually type a total from one spreadsheet into another and call it a digital link. HMRC is explicit about this. Bridging software satisfies the submission requirement but does nothing to help you categorise income and expenses, calculate your tax position, or flag errors before you hit send. For a sole trader managing invoices, materials costs, and mileage, a blank spreadsheet is not a solution; it is the problem you already have, slightly repackaged.
Accounting Software Free Tiers
Several well-known accounting platforms, including FreeAgent, QuickBooks, and Sage, have been trialling or confirming MTD ITSA compatibility. Most of their free tiers, where they exist, either cap the number of transactions, remove bank feed functionality, or require you to upgrade specifically to access the MTD submission feature.
FreeAgent, for example, is genuinely free if you are a customer of certain NatWest Group banks. If you bank elsewhere, the standard price applies. QuickBooks' cheapest plan is pitched at self-employed users but the MTD ITSA quarterly submission feature is tied to a higher subscription tier. Read the feature comparison table carefully before you sign up; it is rarely the headline.
Genuinely Lightweight Options
A small number of newer entrants, including TapTax, have been built specifically for sole traders rather than retrofitted from accounting packages designed for limited companies. The pricing model reflects that. Rather than charging for features a sole trader never uses (payroll, multi-currency, consolidated reporting), the cost is kept low by stripping back to what matters: capturing income and expenses, generating quarterly updates, and submitting them to HMRC on time.
This is not free in the strictest sense, but at a price point designed for a self-employed tradesperson rather than a finance team, it is worth separating from the enterprise-grade tools that dominate the approved list.
What 'Free' Often Costs You in Practice
There is a version of this story where free software is a perfectly reasonable choice. There is also a version where it costs you more than a paid subscription. Here are the ways that gap opens up.
Your Time Is Not Free
A plumber earning £60,000 a year, working five days a week, is earning roughly £230 a day. If a free tool requires two extra hours of manual data entry per quarter compared to an automated alternative, that is £57.50 per quarter in lost earning time, or £230 a year. A paid MTD app that costs £120 a year and saves you those hours is, by that measure, cheaper.
This is not a trivial calculation. HMRC's own impact assessments for MTD estimated that sole traders would spend an average of 30 minutes per quarterly update once they were up and running. That estimate was for software with bank feeds and automated categorisation. Without those features, the time climbs steeply.
Penalties Are Not Free Either
MTD for Income Tax operates on a points-based penalty system. Miss a quarterly deadline and you accumulate a point. Hit four points and you face a £200 fine. The details are explained fully in MTD Penalty for Late Submission: The Points System Exposed, but the key point here is this: software that is confusing, glitchy, or incomplete increases your risk of missing a deadline.
If a free bridging tool fails to connect to HMRC's API on the deadline day, and you do not notice until the window has closed, that is £200 minimum. The software was free. The penalty was not.
Your Data Is the Product
Some free software tools in the accounting space are free because they monetise user data or upsell aggressively once you are locked in. This is not universal, but it is worth asking: if you are not paying for the product, what is the business model? A sole trader putting their income figures, expense patterns, and client payment data into a free tool should understand how that data is stored, who can access it, and what happens to it if the company pivots or closes.
How to Evaluate Any Free MTD Tool Before You Commit
If you are determined to find the lowest possible cost option, here is the checklist that will tell you whether a free tool is actually fit for purpose.
Does It Appear on HMRC's Approved Software List?
This is non-negotiable. If the software is not on HMRC's recognised software list, any submission you make will not be compliant, regardless of how slick the interface looks. Check the list directly rather than relying on the vendor's own claim of compatibility.
Does the Free Tier Actually Include Quarterly Submissions?
Ask specifically: can I submit a quarterly update to HMRC for MTD ITSA on the free plan, without upgrading? Many vendors will answer this vaguely in marketing copy. Get a straight yes or no from the feature comparison page or support team before you invest time in setting up the tool.
Does It Support Digital Linking?
If the tool involves a spreadsheet at any point, does it create a genuine digital link between your source records and the submission, or does it require you to manually enter totals? HMRC's rules on digital links are strict, and manually retyping figures does not comply, even if the final submission goes through an API.
What Happens at the End of Year Final Declaration?
MTD does not eliminate the need for an end-of-year statement; it replaces the annual Self Assessment return with a final declaration that confirms your quarterly figures and adds any additional income or adjustments. Check whether the free tier includes this, or whether it is paywalled. Some tools offer free quarterly submissions but charge for the final declaration, which is the step that actually closes your tax year.
The Honest Bottom Line on Free MTD Software UK
There is no like-for-like free equivalent to what HMRC built for VAT. The closest options are bridging tools that require significant manual effort, or capped free tiers from larger platforms that tend to remove the specific features a sole trader needs.
For some sole traders, particularly those who are comfortable with spreadsheets and have very simple income structures (one income stream, minimal expenses), a bridging approach may genuinely work. For a builder managing subcontractor payments, materials receipts, and van running costs across fifty transactions a month, it is likely to create more problems than it solves.
The question worth asking is not 'what is the cheapest MTD software?' but 'what is the cheapest way to get MTD right without it consuming my working week?' Those are different questions, and they often have different answers.
TapTax was built specifically for sole traders who want the simplest possible route to MTD compliance, without paying for a full accounting suite they do not need. If you want to see how it handles your specific situation, you can try it at taptax.co.uk.
For a full breakdown of what MTD-compatible software does and does not have to include, Making Tax Digital Compatible Software: What HMRC Won't Tell You covers the technical requirements without the marketing gloss. And if you are still working out exactly when you need to be compliant, Making Tax Digital April 2026: What Sole Traders Must Do has the key dates.
The search for free MTD software in the UK is not unreasonable. Just make sure that what you find is actually free of the things that cost you most: your time, your compliance, and your peace of mind come January.
