Making Tax Digital Software: Stop Paying for Features You'll Never Use

Most making tax digital software on the market was not built for you. It was built for the accountant sitting between you and HMRC, and you are being charged accordingly.

If you are a sole trader turning over somewhere between £50,000 and £80,000 a year, you are about to be legally required to use making tax digital software from April 2026. The question is not whether you need it. The question is whether the software industry's answer to your problem is actually solving it, or just adding a new monthly invoice to your life.

The Promise vs. the Reality

When HMRC announced Making Tax Digital for Income Tax Self Assessment (MTD for ITSA), it made a commitment: this would reduce the administrative burden on small businesses. Quarterly submissions, HMRC said, would mean fewer nasty surprises at the end of the tax year. You would have a running picture of what you owe.

The reality is somewhat different. HMRC quietly shelved its plans for a free filing tool for sole traders in 2022, leaving the market entirely to private software vendors. Those vendors, quite rationally, built products aimed at their most profitable customers: small businesses, limited companies, and the accountancy practices that serve them.

The result is that a sole trader electrician in Swindon now has to navigate a software market designed for a 20-person marketing agency. That is not a personal failing on the electrician's part. It is a structural problem that nobody in the press release about MTD's benefits bothered to mention.

Why Most MTD Software Is Overkill for Sole Traders

Open the pricing page of any of the major accounting software providers and you will find plans layered like a wedding cake: Starter, Standard, Premium, and something called Ultimate that costs more per month than a decent meal out. Each tier unlocks features you almost certainly do not need.

Payroll? You are self-employed. You do not have staff. VAT filing? Not applicable if you are under the £90,000 VAT threshold. Multi-currency invoicing? You are fixing boilers in Birmingham, not billing clients in Singapore.

Yet these features are bundled into the pricing model because they were built for a different customer. You are paying for them whether you use them or not.

For a tradesperson earning £60,000 a year, £360 in software fees represents 0.6% of turnover before a single expense has been claimed. That is before you factor in the time spent learning a system built for someone with a finance background.

The Five Submissions Problem Nobody Talks About

Under MTD for ITSA, you will submit five times per year: four quarterly updates and one end-of-period statement. The quarterly updates report your income and expenses for each three-month period. They do not have to be perfectly accurate at the time of submission, but they do have to be submitted on time.

Miss a quarterly deadline and the late submission penalties kick in. Under the new penalty points system HMRC introduced in 2023, each missed deadline earns a penalty point. Accumulate enough points and you face a £200 fine, with further daily penalties accruing for returns more than 30 days overdue. For a sole trader who files quarterly, that is four more opportunities per year to incur a penalty compared with the current annual Self Assessment system.

The software you choose needs to make those five annual submissions as frictionless as possible. If logging in to file a quarterly update takes 20 minutes of hunting through menus designed for a bookkeeper, you will start avoiding it. And avoidance is exactly how penalty points accumulate.

This is worth reading alongside our post on MTD for Self Employed Project Managers: The Cash Flow Trap, which covers how quarterly submissions interact with irregular income patterns in ways HMRC's guidance glosses over.

What to Actually Look For in MTD Software

Strip away the marketing language and you need making tax digital software to do three things reliably:

1. Capture income and expenses quickly

You are not doing double-entry bookkeeping. You are recording what came in and what went out. The interface should reflect that. If categorising a receipt requires more than three taps on a phone, the software was not designed for someone working from a van.

For a deeper look at whether receipt scanning actually helps, our post Receipt Scanner for MTD UK: Does It Actually Save Time? runs through the evidence honestly.

2. Submit to HMRC without drama

The software must be on HMRC's list of recognised making tax digital software. This is not optional. You cannot file MTD submissions through HMRC's own website portal in the same way you currently submit Self Assessment returns. You need a compatible third-party application.

HMRC maintains a regularly updated list of compatible software on GOV.UK. Before paying for anything, check it is on that list. Some free tools with limited functionality appear there. Most of the well-known names appear there too.

3. Give you a running tax estimate

This is the feature that actually delivers on MTD's promise. If your software shows you a live estimate of your tax liability as the year progresses, you can set aside the right amount each quarter rather than facing a brutal January calculation. Our Self Employed Tax Estimator 2026: Stop Guessing Your Bill explains why this matters more as income approaches the higher rate threshold.

The Free Tier That Never Was

It is worth pausing on HMRC's broken promise here, because it matters for how you evaluate the market.

In the original MTD roadmap, HMRC indicated that a free software option would be available for the simplest cases, specifically sole traders with straightforward income and no employees. By 2022, that commitment had been quietly reduced to a list of "free tools" that, on closer inspection, were either severely limited in functionality, designed as loss-leaders to upsell paid plans, or applicable only to businesses below certain income thresholds.

The software industry lobbied hard during the MTD consultation process. The Federation of Small Businesses raised concerns as early as 2019 that mandating paid software would impose disproportionate costs on the smallest businesses. Those concerns were noted and largely set aside.

The net effect: every sole trader above the threshold must pay a private company to fulfil a legal obligation created by HMRC. There is a certain irony in a government programme designed to reduce tax evasion generating guaranteed revenue for software vendors, but here we are.

For a fuller examination of who benefits from the MTD ecosystem, our post Making Tax Digital Accountant Software: Who Is It Really For? follows the money in uncomfortable detail.

A Concrete Example: The Plumber on £65,000

Meet Dan. He is a self-employed plumber in Coventry turning over £65,000 a year. His expenses are straightforward: materials, van costs, tools, and a proportion of his phone bill. He does not have employees. He does not invoice internationally. He does not need payroll software.

Dan currently files one Self Assessment return per year, usually in January, usually in a panic. Under MTD for ITSA from April 2026, he will file four quarterly updates plus an end-of-period statement.

If Dan signs up for a mid-tier plan from one of the major accounting software providers, he is looking at around £35 per month: £420 per year. That plan includes payroll for up to five employees (Dan has none), VAT submissions (Dan is VAT-registered but his accountant handles this), and project tracking dashboards he will never open.

If Dan chooses software built for sole traders with simple income, he might pay £10 to £15 per month. Same HMRC compliance. Fewer menus. Quarterly submissions that take five minutes rather than twenty.

The difference is £240 to £300 per year. Over the five years to 2031, that is up to £1,500 in software fees Dan spent on features designed for someone else's business.

What the Mileage Question Reveals About a Product's Design

Here is a quick litmus test for any making tax digital software you are evaluating: how does it handle mileage claims?

For most tradespeople, mileage is one of the largest allowable expenses. HMRC's approved mileage rate is 45p per mile for the first 10,000 business miles, dropping to 25p thereafter. A plumber driving 12,000 business miles a year can claim £4,750 in mileage allowance, reducing their taxable profit substantially.

If the software requires you to manually enter each journey in a separate log, calculate the mileage, apply the rate, and then categorise the resulting figure as a motor expense, it was not built with a tradesperson in mind. If it has a mileage tracker built into the mobile app that does the arithmetic for you, someone thought about your workflow. Our Mileage Claim Calculator: Stop Leaving Cash on the Road shows exactly how much most sole traders are under-claiming on this single expense.

The Registration Trap

One more practical point that catches sole traders off guard: signing up for making tax digital software is not the same as registering for MTD with HMRC.

You need to do both, and HMRC's registration process can take several weeks to complete. HMRC has issued guidance recommending that sole traders register at least three months before their first quarterly deadline. For those entering MTD in April 2026, that means registering no later than January 2026.

If you miss the registration window and cannot file your first quarterly update on time, you accumulate a penalty point regardless of whether the failure was caused by HMRC's own processing delays. The system does not make allowances for the fact that HMRC's registration portal has historically been slow.

This issue affects different trades and locations in similar ways. Whether you are in Taunton or Walsall, the registration timeline is the same and the consequences of missing it are identical.

How to Evaluate a Demo

Before committing to any making tax digital software, ask for a demo or a free trial and run through this specific sequence:

1. Record three income transactions from your phone.
2. Record two expense transactions, one with a photo of a receipt.
3. Log a mileage claim for a 47-mile journey.
4. View your estimated tax liability for the current quarter.
5. Run through the steps to submit a quarterly update to HMRC.

Time yourself. If the entire sequence takes more than fifteen minutes the first time and more than five minutes once you know the system, the software has a friction problem. Friction is how quarterly submissions become something you dread, which is how penalty points happen.

The Right Software Is the One You Will Actually Use

The making tax digital software market will mature. Prices will probably fall as competition increases and HMRC potentially revisits the free-tier question under political pressure. But April 2026 is not waiting for the market to sort itself out.

The question you opened with, implicitly, is whether there is a version of this that does not feel like another invoice from a system designed to extract money from people who just want to do their job. The answer is yes, but you have to look past the feature lists built for bigger businesses and ask the only question that matters: will this make five annual submissions easier than one annual panic?

If you are ready to see what making tax digital software built specifically for sole traders looks like, rather than accounting suites retrofitted for them, TapTax was designed for exactly this scenario.
