Free Software for Making Tax Digital: What HMRC Won't Tell You

HMRC will fine you for not using software it refuses to build for free. That is the quiet absurdity sitting at the heart of Making Tax Digital, and it is worth naming plainly before we get into what free software for Making Tax Digital actually exists, what it costs you in other ways, and why the "free" label deserves serious scepticism.

Why Free MTD Software Is a Political Question, Not Just a Product Question

When HMRC designed the MTD for Income Tax regime, it faced a fork in the road: build a free, government-owned submission tool (as some other tax authorities do), or mandate third-party software and let the market handle it. It chose the latter. The official position, buried in various consultations and impact assessments, is that the private sector can serve sole traders adequately.

The practical consequence is that roughly 700,000 sole traders and landlords with income above £50,000 are already required to comply from April 2026, with a further wave at £30,000 from April 2027. Every single one of them must use HMRC-approved software to do so. Not because it is technically impossible to build a free government portal, but because HMRC decided it should not.

This matters when you search for free software for Making Tax Digital, because what you are really searching for is a private company willing to subsidise your compliance costs. Some do, up to a point. But it is worth understanding who is paying, and how.

What Actually Exists in the 'Free' Category

HMRC maintains a list of software recognised for MTD for Income Tax. As of 2025, the free or freemium options broadly fall into three buckets.

Free Tiers of Paid Products

Several accounting platforms, including some well-known names, offer a free tier that technically supports MTD submissions. The catches are consistent across almost all of them:

• Submission limits. Free tiers often cap you at a single business or a single tax year before pushing you to upgrade.
• Feature restrictions. Receipt capture, bank feed integration, and automatic expense categorisation, the features that actually save you time, tend to sit behind a paywall.
• Upsell pressure. Free tiers are loss leaders. The product roadmap is built to nudge you toward a paid plan within six to twelve months.

If you are a plumber turning over £55,000 a year, the free tier of a major accounting platform might handle your quarterly submissions, but you will likely be doing manual data entry to get there. The software is free; your time is not.

Bridging Software

Bridging software is the most genuinely low-cost legitimate route for some sole traders. Products in this category let you keep records in a spreadsheet, then use the bridging tool to push that data to HMRC in the correct format. Prices for bridging tools range from free to around £10 per year, which makes them the cheapest MTD-compliant option in cash terms.

The trade-off is real, though. You are still responsible for maintaining accurate digital records in your spreadsheet. If your records are wrong, the submission is wrong. HMRC does not care that your spreadsheet formula had a rounding error. Bridging software is a compliance wrapper, not an accounting system.

For a sole trader with genuinely simple finances, say a handyman with a handful of regular clients, consistent invoice amounts, and minimal expenses, bridging software is a defensible choice. For anyone with variable income, mixed business and personal spending, or irregular cash transactions, the manual overhead quickly becomes its own tax on your time.

HMRC's Own Free Tool (Spoiler: It Does Not Exist)

Some sole traders assume HMRC must offer something free, as it does for VAT returns via its own portal. For MTD for Income Tax, no equivalent government-built free tool exists. HMRC tested a limited "digital handshake" approach during the pilot phase but has not committed to a free submission service at scale. The government's impact assessment acknowledges compliance costs will fall on businesses and individuals. It simply decided that was acceptable.

This is worth stating clearly because searches for free software for Making Tax Digital sometimes lead people to HMRC's own website, where the absence of a free tool is conspicuous but not labelled as such. You will find a list of approved software. You will not find a free one bearing the HMRC logo.

The Hidden Cost of 'Free': Your Time as a Sole Trader

If you earn £60,000 as an electrician and you value your time at even a modest £25 per hour, spending an extra three hours per quarter on manual data entry for a free bridging tool costs you £300 per year in opportunity cost. A paid MTD app at £10 per month costs £120. The maths is not always flattering for the free option.

This is not an argument against free software. It is an argument for honest accounting of what free actually means. The real question is not "is this product free?" but "what is the total cost of staying compliant with this product?"

That total includes:

• Time spent on data entry if the free tool does not automate categorisation or bank feeds
• Error risk if manual processes introduce mistakes that trigger HMRC queries
• Mental load of remembering four quarterly submission deadlines plus a final annual declaration
• Penalty exposure if the free tool's UX causes you to miss a deadline. MTD penalties under the new points-based system accumulate: four penalty points in a year triggers a £200 fine, with further daily charges for extended non-compliance

As we explored in Making Tax Digital Software: Stop Paying for Features You'll Never Use, the answer is not always to pay more. But it is to pay attention to what you are actually buying.

Who Benefits From the 'Free' Framing?

Software companies offering free MTD tiers are not charities. The business model is straightforward: acquire users at zero marginal cost, demonstrate value, convert to paid. The free tier is a customer acquisition channel, and a very effective one when the government has mandated that every sole trader above a threshold must use your category of product.

Some sole traders will use a free tier indefinitely and never upgrade. The software company bets that enough users will convert to make the economics work. This is not sinister; it is how freemium software operates across every industry. But it is useful to know that the "free" MTD software market exists because HMRC created a captive audience and declined to serve it directly.

What to Look for If Free Is a Hard Requirement

If budget is genuinely the constraint, here is what separates a usable free MTD product from a frustrating one.

HMRC Recognition, Not Just Claims

Any product you use must appear on HMRC's published list of software compatible with MTD for Income Tax. Do not take a product's own marketing as confirmation. Check the HMRC list directly. Some tools market themselves as MTD-ready while technically still in development or testing.

Quarterly Submission Support

MTD for Income Tax requires four quarterly updates per year plus an end-of-period statement and a final declaration. A free tool that only supports one or two submissions before hitting a paywall is not a free solution for a full tax year.

Digital Record Keeping, Not Just Submission

MTD requires digital records of income and expenses, not just digital submission. A tool that only submits totals without letting you store the underlying transactions is technically compliant only if you maintain those records elsewhere in a digital format. Spreadsheets qualify; paper notebooks do not.

Usable on Mobile

If you are a tradesperson, you are not doing your accounts at a desk. A free MTD tool that only works on desktop is going to gather dust. The Receipt Scanner for MTD UK: Does It Actually Save Time? post covers what mobile-first record keeping actually looks like in practice.

The Threshold Timeline: Why This Decision Is Urgent

If your self-employment or property income exceeds £50,000, MTD for Income Tax is mandatory from April 2026. At £30,000, the obligation starts April 2027. At £20,000 (the next planned threshold), the date is still to be confirmed but is expected later in the 2020s.

This is not distant. If you are reading this in 2025, the April 2026 cohort has less than a year to find a compliant solution, test it, and migrate their records. Choosing a free tool and then discovering its limitations three months before your first quarterly deadline is a known pattern from the MTD for VAT rollout. Do not repeat it.

If you are close to but under the threshold, MTD Under the Threshold: Are You Actually Safe? is worth reading before you assume you are exempt.

A Realistic Assessment for a Sole Trader Earning £55,000

Imagine you are a self-employed carpenter earning £55,000. You have about 80 transactions per quarter: a mix of material purchases, tool costs, fuel, and client invoices. Here is how the free options realistically perform for you.

Free bridging software: You maintain a spreadsheet, manually entering each transaction. Once a quarter, you open the bridging tool, upload your totals, and submit. Time per quarter: roughly two to three hours if you have kept your spreadsheet current. Annual cash cost: near zero. Annual time cost: eight to twelve hours. Error risk: moderate, because manual entry at volume produces mistakes.

Free tier of a full accounting platform: You log transactions as they happen through a mobile app. The app categorises some automatically via bank feeds (if the free tier includes this). Quarterly submission is built in. Time per quarter: forty-five minutes to an hour. Annual cash cost: zero until the free tier limit is hit, then £10 to £20 per month. The free tier may last one tax year before prompting an upgrade.

Low-cost paid MTD app: Bank feeds, automatic categorisation, mobile receipt capture, and quarterly submissions in one product. Annual cost: £60 to £120. Time per quarter: thirty minutes or less.

For the carpenter in this scenario, the "free" option is unlikely to remain free across a full tax year at any meaningful feature level. The bridging route works but at a real time cost. The low-cost paid app often wins on total cost once time is factored in.

The Honest Conclusion on Free Software for Making Tax Digital

Free software for Making Tax Digital exists. Whether it is genuinely free for your specific situation depends on your transaction volume, technical comfort, and how honestly you account for your own time. HMRC's decision not to build a free government tool has created a market where "free" often means "free to start, cost-to-continue" or "free in money, expensive in time."

The question you started with, what free software exists for Making Tax Digital, is the right question. The more useful follow-up is: what is the actual total cost of staying compliant, and which tool minimises that cost across money and time combined?

If the answer to that question points toward a low-cost paid app rather than a genuinely free bridging tool, that is not a failure of your budget. It is a consequence of HMRC mandating a compliance system it chose not to fund.

Start by checking HMRC's approved software list directly, then map your own transaction volume against each option. If you clear £50,000 in self-employment income, you have until April 2026. That is not long enough to make this decision twice.
