MTD Software for Self Employed: Are You Buying Too Much?
Most MTD software for self employed people is built for accountants, not tradespeople. Here's how to spot what you actually need and avoid paying for what you don't.
Most MTD software for self employed people was designed for a finance director, not a plasterer finishing a job at 6pm. If you have ever opened QuickBooks or Sage and felt like you'd accidentally logged into NASA's mission control, that reaction is not a sign of incompetence. It is a sign that the software was built for someone else.
The MTD software market is worth an estimated £1.5 billion annually in the UK, and sole traders represent the largest single segment of users being funnelled into it from April 2026. Understanding what you actually need, versus what vendors are eager to sell you, is the difference between a £12-a-month tool that does the job and a £50-a-month subscription with 47 features you will never touch.
- MTD software for self employed people does not need to be complex. You need digital record-keeping, quarterly submissions, and a final declaration. That is it.
- Most mainstream software packages are priced and designed for small businesses with employees, not sole traders. You are paying for features built for someone else.
- HMRC does not endorse any single product. The approved software list includes dozens of options at wildly different price points.
- The quarterly submissions under MTD are not tax payments. They are summaries of income and expenses. Your software should make that a five-minute task, not a half-day project.
- Switching MTD software mid-year is possible but messy. Choosing the right tool before April 2026 saves a significant headache later.
What MTD Software for Self Employed Actually Has to Do
Before you spend a penny, it helps to understand the legal minimum. Making Tax Digital for Income Tax Self Assessment (MTD for ITSA) requires three things from your software:
- Digital record-keeping of income and expenses
- Four quarterly updates submitted directly to HMRC via the API
- A final declaration at the end of the tax year (replacing your Self Assessment return)
That is the full legal obligation. Everything else, bank feeds, payroll modules, VAT returns, project tracking, invoicing suites, multi-currency support, is optional. Some of it is genuinely useful. Much of it is a pricing mechanism.
- MTD for ITSA
- Making Tax Digital for Income Tax Self Assessment. HMRC's requirement that self employed individuals and landlords with qualifying income keep digital records and submit quarterly updates to HMRC using approved software, replacing the annual Self Assessment return.
If you are a sole trader turning over £55,000 a year as an electrician, a painter, a freelance designer, or a driving instructor, your tax affairs are genuinely not complicated. You have income coming in. You have expenses going out. You owe tax on the difference, minus your personal allowance and any reliefs. A quarterly MTD submission is just a running total of those two columns, sent to HMRC every three months so they can see how the year is shaping up.
The software does not calculate your final tax bill in those quarterly updates. It does not trigger a payment. It is, in HMRC's own words, a summary update. Yet the software market would have you believe you need a subscription that also manages your pension contributions, generates branded invoices, and integrates with Shopify.
Why the Market Is Structured Against Sole Traders
The UK's small business software market has a fundamental tension. The most profitable customers are small businesses with a handful of employees, a VAT registration, and a bookkeeper who logs in weekly. Those customers justify a £40-60 monthly subscription because the software genuinely saves them hours of manual reconciliation.
Sole traders, particularly tradespeople, are not that customer. They typically have one income stream, a manageable number of regular expenses (fuel, materials, tools, insurance, van costs), and no employees. They do not need double-entry bookkeeping. They need a digital logbook that talks to HMRC.
The problem is that major software vendors built one product and priced it for the more complex use case. Then MTD created a legislative mandate that suddenly funnelled millions of sole traders through that same door.
The result: a tradesperson who files one Self Assessment a year and has never opened a spreadsheet is being asked to subscribe to software designed for a company with a finance function. As we covered in HMRC Compatible Tax Software: Why Most Fail Sole Traders, the gap between what HMRC mandates and what vendors deliver is significant.
The Feature Trap: Paying for Things You Will Never Use
Here is a concrete illustration. A self employed plumber earning £62,000 a year signs up for a mid-tier QuickBooks plan at £30 a month (£360 a year) after being targeted by an MTD awareness campaign. The plan includes:
- Payroll for up to three employees (no employees)
- VAT return filing (not VAT registered)
- Multi-currency invoicing (all UK clients)
- Inventory management (not relevant to a service business)
- Profit and loss reports by department (one department: plumbing)
- Integration with Stripe and PayPal (paid in cash or bank transfer)
Of the roughly twenty features in the plan, the plumber uses three: income logging, expense categorisation, and the quarterly MTD submission. He is paying £360 a year for the equivalent of a digital notebook with an API connection.
This is not a hypothetical edge case. It is the dominant experience of sole traders entering the MTD software market for the first time. The TapTax vs QuickBooks: Honest Verdict for Sole Traders comparison lays out exactly how this pricing disparity works in practice.
What to Actually Look for in MTD Software
Core compliance features (non-negotiable)
Any software you choose must appear on HMRC's list of recognised MTD for ITSA compatible products. This is not optional. Software that is not API-connected to HMRC cannot submit quarterly updates, which means it does not satisfy your legal obligation regardless of how good its other features are.
Beyond HMRC recognition, you need:
Simple income and expense logging. You should be able to record a payment in under thirty seconds. If the interface requires you to select a nominal code, assign a project, choose a tax treatment, and attach a document before saving a £40 fuel receipt, the software has failed you.
Quarterly submission in one tap. The MTD submission itself is a straightforward data transfer. Your software should aggregate your income and expenses for the quarter and send them to HMRC with minimal input from you. If your accountant needs to review and approve each submission, you are using accountant-facing software.
A final declaration workflow. At the end of the tax year, you will need to confirm your income figures, add any additional income sources (savings interest, rental income if applicable), claim reliefs, and submit the final declaration. This replaces Self Assessment. Your software must support this step.
Genuinely useful extras for sole traders
Some features beyond the legal minimum are worth having. Bank feed integration, where your software pulls transactions directly from your business bank account, genuinely saves time and reduces the chance of missing an expense. Mileage tracking matters if you drive for work and claim business miles, since HMRC's approved mileage rate of 45p per mile for the first 10,000 miles can add up to a significant deduction on a £62,000 income. Receipt capture via a phone camera is convenient, though not strictly necessary if you keep digital records another way.
What you almost certainly do not need: payroll, VAT, multi-currency, inventory, project profitability reporting, or CRM integration. If a vendor is charging you for a tier that includes these features because that is the only tier with MTD support, that is a vendor problem, not a compliance requirement.
Price as a signal
This is worth stating plainly. The price of MTD software has no correlation with compliance quality. HMRC does not tier its API access by subscription level. A £9-a-month product that is on the recognised software list files exactly the same quarterly update to exactly the same HMRC systems as a £55-a-month product. The difference is in the surrounding features, the interface quality, and the level of accountant-facing complexity.
For a sole trader with straightforward accounts, simpler and cheaper is usually better, not a compromise.
The Switching Problem Nobody Warns You About
One underappreciated risk in the MTD software market is lock-in. If you choose a product in April 2026, get six months into the tax year, and realise it is overpriced or too complex, switching is genuinely awkward. Your year-to-date income and expense records sit inside the old software. You either need to export them (if the software allows it in a usable format) or manually re-enter them into the new product. Mid-year switches also create risk around quarterly submissions: which software submitted Q1, which is handling Q2, and are both connected to HMRC's systems correctly?
This is not an argument for paralysis. It is an argument for making the right choice before the tax year starts. If you are planning to comply from April 2026 (the current start date for sole traders with income over £50,000; check When Do I Need to Start MTD? Your Deadline by Income for the precise thresholds), you have time to trial two or three products now, before it is live and legally consequential.

The Honest Trade-Off Between Simplicity and Flexibility
There is one legitimate argument for more complex, feature-rich software: growth. If you expect your business to take on an employee in the next two years, or to register for VAT as turnover approaches the £90,000 threshold, buying into a platform that handles those scenarios now avoids a migration later. That is a reasonable calculation for some sole traders.
But it requires honesty about your actual trajectory. A handyman earning £58,000 who has traded at roughly that level for five years is not the same as a freelance consultant whose client roster is growing at 30% a year. The first person is not planning for payroll. The second might be.
If growth is genuinely on the horizon, the right question is not whether to choose complex software, but whether to choose software with a clear upgrade path, so you start on a simple, affordable tier and move up only when you need the features.
MTD Software for Self Employed: The Decision Framework
Cut through the marketing noise with three questions:
Is it on HMRC's recognised software list? If no, walk away regardless of price.
Can I log income and expenses in under a minute per transaction? If the answer requires watching a tutorial, it is not built for you.
Does the pricing tier I actually need include everything legally required for MTD? Quarterly submissions and a final declaration must be included, not locked behind a more expensive plan.

The Bottom Line
The question at the top of this post was whether you are buying too much. For most self employed sole traders entering the MTD market for the first time, the honest answer is: probably yes, if you follow the default recommendations from major software vendors.
MTD software for self employed people does not need to be expensive, complex, or feature-heavy to be fully compliant. It needs to be on HMRC's list, easy enough that you actually use it every week, and priced for one person running one business, not for a startup with ambitions of a Series A.
The best place to start is a free trial of the simplest product that meets all three criteria. If it handles a quarterly submission without requiring you to phone a support line, it is doing its job.
