Free MTD Software for Sole Traders: The Honest Truth

HMRC mandated that every sole trader above the income threshold must use software to file quarterly MTD returns. Then it quietly declined to build any. So who pays? You do, apparently, unless you know exactly where to look.

The search for free MTD software for sole traders is one of the most common queries on the internet right now, and the answers floating around are, to put it charitably, incomplete. Some are outright misleading. This post names names, explains the hidden costs the marketing pages bury, and tells you what actually costs nothing versus what will cost you the moment your free trial expires.

Why Free MTD Software Is Rarer Than You Think

Let's start with an uncomfortable fact. HMRC's own guidance confirms that taxpayers must use "compatible software" to keep digital records and submit quarterly updates under Making Tax Digital for Income Tax Self Assessment (MTD ITSA). What HMRC does not do is provide that software itself.

In 2023, the Public Accounts Committee raised concerns about the burden MTD places on small businesses. The government's response was essentially: the market will provide. And the market has provided, in the same way that a petrol station provides a tyre pump, one that technically works but costs £1 every four minutes.

The result is a software market where "free" almost always means one of three things:

1. Free for a limited trial period (usually 30 days)
2. Free for a stripped-back tier that cannot actually submit MTD quarterly updates
3. Free as a loss-leader, with paid add-ons required for anything useful

None of these are genuinely free MTD software for sole traders. They are conversion funnels dressed up as public services.

The Providers That Claim to Be Free

Several well-known software vendors advertise free or low-cost tiers. Here is what those tiers actually include when you read the small print.

QuickBooks Self-Employed

QuickBooks offers a self-employed tier that has historically been positioned as suitable for sole traders. However, as of 2025, QuickBooks Self-Employed does not support MTD ITSA quarterly submissions. It is a mileage and expense tracker, not an MTD-compliant filing tool. Intuit, which owns QuickBooks, has confirmed it is transitioning users to QuickBooks Online for MTD purposes, at significantly higher monthly prices. The free-ish entry product does not do what you need it to do.

FreeAgent

FreeAgent is genuinely MTD-compliant and has a good reputation among freelancers. It is also not free. It costs around £19 per month (after any introductory discount). There is one notable exception: FreeAgent is available at no charge if you have a NatWest, Royal Bank of Scotland, or Ulster Bank business account. If you bank with one of those three, this is worth investigating. If you do not, FreeAgent is a paid product.

Wave Accounting

Wave is a US-based product with free bookkeeping features. It does not support UK MTD submissions. Full stop. Any sole trader using Wave to manage their books will still need a separate, compliant tool for their quarterly updates. That means paying twice.

HMRC's Own "Free" Filing Option

HMRC does maintain a page listing software that supports MTD. Some providers on that list offer free tiers. The catch is that HMRC's list is self-certified by vendors, not independently audited for quality or usability. A product can appear on the approved list and still be painful to use. Always cross-reference user reviews before committing.

What Genuinely Low-Cost Looks Like

The honest answer to "free MTD software for sole traders" is this: truly free, fully compliant, indefinitely usable options are exceptionally rare. But genuinely low-cost options, designed specifically for sole traders rather than small businesses with staff and stock, do exist and the price difference compared to full accounting suites is significant.

The problem with most mainstream accounting software is that it was built for small businesses broadly, not sole traders specifically. You end up paying for payroll features, multi-currency invoicing, and inventory management you will never use. As we covered in Making Tax Digital Software: Stop Paying for Features You'll Never Use, the average sole trader needs about 20% of what most software packages offer, but pays for 100% of them.

A legitimate low-cost option for a straightforward sole trader (single income stream, no employees, no VAT registration) should do the following:

• Digital record-keeping for income and allowable expenses
• Automatic categorisation of common expense types
• Quarterly submission to HMRC in the correct MTD format
• A running estimate of tax owed (critical for avoiding cash flow shocks)
• A final declaration at year end

That is the full MTD requirement. Nothing more is strictly necessary. If a tool does those five things and costs under £10 per month, it is competitive. If it does them and costs under £5, it is exceptional. If it genuinely costs nothing and appears on HMRC's approved software list, verify that claim with extreme scepticism before trusting it with five years of potential tax liability.

The Spreadsheet Bridging Option

For sole traders who are deeply attached to their Excel or Google Sheets setup, bridging software deserves a mention. Tools like DataDear or Sheetful act as a connector between your spreadsheet and HMRC's MTD API, meaning you keep your existing records format but route submissions through a compliant channel.

This approach has real appeal for tradespeople who have spent years building spreadsheets that work exactly how they want. The monthly cost is typically lower than full accounting software, running between £5 and £15 depending on the provider.

The downsides are genuine, however. You are responsible for the accuracy of your spreadsheet categorisation. There is no automatic sense-checking, no running tax estimate unless you build one yourself, and setup is more involved than downloading an app. If you are a plumber who wants to log a payment while standing in a customer's kitchen, opening a spreadsheet on your phone and then syncing it through bridging software is not a frictionless experience.

For sole traders with complex or variable income, we have explored specific scenarios in posts like MTD for Self Employed Project Managers: The Cash Flow Trap and Freelance Developer Sole Trader Tax UK: The MTD Trap, where the simplicity argument breaks down quickly.

Why HMRC Chose Not to Build a Free Tool

This question is worth asking directly, because the answer illuminates the politics behind your software subscription.

HMRC did consider building its own free MTD tool, referred to in internal planning documents as a "basic digital tool." It decided against it. The official rationale was that the private sector was better placed to deliver innovation. The less official reality, visible in the lobbying patterns around MTD's development, is that established software vendors had a strong commercial interest in HMRC not competing with them.

The result is a policy that is mandatory, government-mandated, and entirely outsourced to private companies who charge you monthly to comply with a legal obligation. There is a certain audacity to it. HMRC collects additional tax revenues more efficiently; software companies collect subscription fees; sole traders collect the bill.

The National Audit Office noted in its 2023 review of MTD that the programme had already been delayed four times and that concerns about costs to small businesses remained unresolved. Those costs are not abstract. For a sole trader turning over £55,000, paying £25 per month for accounting software represents roughly 0.5% of gross income spent purely on tax administration infrastructure. That is before accountant fees, before the time cost of quarterly filing, before the cognitive overhead of learning new systems mid-business-year.

What to Actually Look For in Low-Cost MTD Software

If your budget is tight and your tax situation is simple, here is the checklist that matters:

Non-negotiable:

• Appears on HMRC's list of MTD ITSA compatible software
• Can submit quarterly updates directly to HMRC (not just export a CSV)
• Includes a final declaration function for year-end
• Actively maintained, with updates planned for the April 2026 MTD ITSA rollout

Strongly recommended:

• Running tax liability estimate (so you are not shocked at payment time)
• Expense categorisation aligned with HMRC's allowable expense categories
• Receipt capture via mobile camera
• Clear pricing with no hidden submission fees

Nice to have but not essential for most sole traders:

• Invoicing features
• Bank feed integration
• Multi-currency support
• Payroll

If a product charges extra for quarterly submissions on top of the base subscription, walk away. That is a structural pricing decision designed to extract money from the compliance process itself, not from the value the software adds.

TapTax: Built for Sole Traders, Priced Accordingly

TapTax was designed specifically for sole traders who need MTD compliance without the overhead of full accounting software. It is not built for businesses with employees, stock management, or multi-entity structures. It is built for you: a tradesperson, freelancer, or self-employed professional who needs to log income and expenses, submit quarterly updates, and get on with their actual job.

The pricing reflects that focus. There are no payroll modules inflating the cost. No invoicing suite you will never use. Just the MTD compliance features a sole trader actually needs, at a price that reflects the scope of what you are buying.

If you have been holding off on sorting your MTD setup because every tool you have looked at seems designed for a small business ten times your size, TapTax is worth a look. You can explore what TapTax offers here before committing to anything.

And if you are not yet sure whether you are above the MTD threshold or what your likely tax bill looks like, the Self Employed Tax Estimator 2026 is a useful starting point before you choose any software at all.

The Bottom Line on Free MTD Software

We started with a simple question: is there genuinely free MTD software for sole traders? The honest answer is: almost never, but nearly-free exists and is often more than adequate.

HMRC chose not to build a free tool. Software vendors filled the gap, mostly with products priced for businesses, not individuals. The "free" tiers advertised by major providers either cannot actually file MTD returns or expire after a trial. Bridging software is cheaper than full accounting suites but adds friction that most working tradespeople do not need.

What sole traders actually need is software that is cheap, simple, and unambiguously on HMRC's approved list. That combination exists. It just requires looking past the products with the largest marketing budgets and the most confusing pricing pages.

The best next step today: check HMRC's approved software list at gov.uk/guidance/find-software-thats-compatible-with-making-tax-digital-for-income-tax, filter for products that support sole trader income type, and then check whether quarterly submissions are included in the base price or cost extra. That single filter will eliminate most of the false "free" options immediately.
