MTD Software for Small Business: Stop Paying for Features You'll Never Use

April 2026 is closer than it feels, and if you're a sole trader earning above £50,000, HMRC's Making Tax Digital for Income Tax is no longer a rumour you can safely ignore. But here's the problem nobody in the software industry wants to say plainly: most MTD software for small business was not built for you.

It was built for accountants managing fifty clients, or for limited companies with payroll departments. You, the self-employed electrician or freelance consultant juggling invoices between jobs, are an afterthought. The result is software packed with features you'll never touch, priced accordingly, and designed in ways that assume you have a bookkeeper to hand.

This post is not another comparison table. It's a buyer's warning: here is what the market is selling, here is what a small business actually needs from MTD software, and here is how to stop paying for the gap between the two.

What MTD for Income Tax Actually Requires You to Do

Making Tax Digital for Income Tax (MTD for ITSA)

HMRC's programme requiring sole traders and landlords above the income threshold to keep digital records and submit quarterly updates of income and expenses, plus an End of Period Statement and Final Declaration, using HMRC-compatible software.

Before buying anything, it is worth being precise about what MTD for Income Tax actually demands, because software vendors have a commercial incentive to make it sound more complex than it is.

From April 2026, if your total income from self-employment and property exceeds £50,000, you must:

1. Keep digital records of your income and expenses
2. Submit four quarterly updates to HMRC each tax year (essentially summaries of those records)
3. Submit an End of Period Statement confirming your figures
4. Submit a Final Declaration replacing your current Self Assessment return

That is five submissions per year instead of one. But the quarterly updates are not full accounts. They are categorised summaries: how much you earned, how much you spent on allowable categories like travel, materials, and tools. HMRC does not want your individual receipts. It does not need a profit-and-loss statement formatted for a bank manager. It needs totals, in the right boxes, on time.

A sole trader plumber turning over £65,000 a year, with straightforward trade income and a handful of expense categories, does not need the same software as a fifty-person construction firm. The market, however, is doing its best to convince them otherwise.

The Feature Bloat Problem

Open any of the major MTD-compatible software platforms and you will find a product built to serve the broadest possible market. That means payroll modules, stock management, project tracking, multi-currency invoicing, and CRM-adjacent contact management. These are legitimate features for legitimate businesses. They are completely irrelevant to a self-employed handyman who invoices fourteen clients a month and buys materials from a builders' merchant.

The bloat is not accidental. Software companies earn more by charging for complexity. The entry-level plans are frequently stripped to the point of uselessness, while the plan that actually supports MTD quarterly submissions sits at tier two or three. It is a classic upsell structure, and it works because most small business owners don't know enough about MTD requirements to call it out.

QuickBooks, for example, charges from around £14 per month for its Sole Trader plan, but the pricing climbs sharply once you want features like VAT bridging or advanced reporting. Xero's Starter plan has transaction limits that many active sole traders would breach within weeks. FreeAgent, popular with freelancers, is genuinely capable but designed with an agency workflow in mind, complete with project time-tracking that most tradespeople have zero use for.

As we covered in HMRC Recognised Software: What the Label Actually Means, HMRC's approval of a software product tells you it can technically submit the right data in the right format. It tells you nothing about whether the product is appropriate for your level of complexity or your budget.

What a Sole Trader Actually Needs From MTD Software

Strip back the marketing and here is the functional list for the typical self-employed tradesperson or freelancer:

Digital record-keeping

You need to record income (money in) and expenses (money out), categorised into HMRC's standard expense categories. This is not double-entry bookkeeping. It is a structured ledger, and it can be genuinely simple.

Quarterly submission capability

The software must be able to package your quarterly totals and submit them to HMRC via the MTD API. This is non-negotiable and the one technical hurdle you cannot work around. Spreadsheets alone will not do it, though HMRC-compatible bridging software can connect a spreadsheet to the API if you prefer to keep your records that way.

An End of Period Statement and Final Declaration

At year end, you'll confirm your figures and make any adjustments for allowances. Most sole traders will find this straightforward, especially if quarterly records are accurate throughout the year.

Import or entry of bank transactions

You need a way to get your transactions into the system. Some software offers direct bank connections via Open Banking. TapTax currently handles this through CSV import, with presets for 16 UK banks so you're not wrestling with column formatting, plus manual entry for anyone who prefers to log transactions as they go. Either approach works for compliance; what matters is that transactions are recorded digitally and categorised correctly.

Simplicity and reliability

This one is not on HMRC's checklist, but it matters enormously in practice. Software you find confusing will either cause errors or cause you to abandon it. Both outcomes are expensive.

The Price You Pay for Features You'll Never Use

Let's make this concrete. Suppose you're a self-employed electrician earning £72,000 a year. You have one income stream (your trade), a van, tools, fuel, materials, and a mobile phone you use for work. Your expense categories number perhaps six or seven.

If you subscribe to a mid-tier plan on a major accounting platform at, say, £30 per month, you are paying £360 per year. A significant portion of that cost funds payroll processing for businesses with employees, inventory management for product-based businesses, and project profitability tracking for agencies. None of it benefits you.

Now consider penalties. Under MTD, HMRC is moving to a points-based penalty system. Miss a quarterly submission and you earn a penalty point. Four points and you face a £200 fine, with further daily penalties for extended failures. The financial incentive to get compliant is real. But the compliance cost should not be inflated by software designed for a business ten times your size.

The right question when evaluating MTD software is not "does it do everything?" It is "does it do everything I need, and nothing I'm paying for unnecessarily?"

Why the Market Underserves Sole Traders

The UK has approximately 4.2 million self-employed people, according to ONS data. A substantial portion of them will fall under MTD for Income Tax by April 2027 when the threshold drops to £30,000. This is a huge addressable market.

So why has the software industry done such a poor job of serving it? Partly because sole traders are less profitable per customer than small limited companies, and partly because the accounting software ecosystem evolved in an era when "small business" software actually meant businesses with at least a handful of employees.

Accountants have also historically been the channel through which software reaches clients. As we examined in Self Assessment Software for Accountants: The Client Trap, accountant-led software adoption often means the client ends up on a product that suits the accountant's workflow rather than their own needs. The self-employed plumber signs up to whatever their accountant recommends, which is whatever the accountant's practice management system integrates with most smoothly.

MTD disrupts this dynamic, at least partially. Because MTD requires the taxpayer themselves to submit quarterly, there is now a stronger argument for software chosen around the taxpayer's own usability needs rather than the accountant's integration preferences.

How to Evaluate MTD Software Without Getting Sold To

Here is a practical filter. Before signing up to anything, ask these questions:

Does this plan actually include MTD quarterly submissions? Check the small print. Many entry-level plans exclude MTD functionality and require an upgrade.

How does it handle bank transaction import? You need a way to get your spending into the system. CSV import is sufficient for most sole traders and avoids the privacy considerations of full Open Banking connections.

Is the expense categorisation aligned with HMRC's categories? The software should map your costs to the categories HMRC uses for self-employment: office costs, travel, clothing, staff costs, raw materials, financial charges, advertising, and so on. If you have to translate categories yourself, you're adding work.

What does the annual cost look like net of any introductory discount? Many platforms offer three or six months free, then bill at full rate. Calculate the twelve-month cost from month seven onwards.

Is there a free tier that genuinely covers MTD, or is it a lead magnet? If the free version cannot actually file with HMRC, it is not MTD software. It is a marketing exercise.

Can you get your data out if you want to switch? Data portability matters. If you're locked into a proprietary format, switching costs will be high, as we explored in Self Employed Bookkeeping Software: The Switching Cost Nobody Warns You About.

The Case for Purposefully Simple MTD Software

Simplicity is a feature, not a limitation. A sole trader does not need their tax software to generate a cash-flow forecast or reconcile stock values. They need it to record what came in, what went out, keep a digital copy of their records, and file quarterly with HMRC without error.

TapTax is built around exactly this idea. There are no payroll tabs, no inventory modules, no project timers. The interface is designed for someone who wants to spend fifteen minutes a month keeping their records tidy, not someone who enjoys software.

CSV import with presets for sixteen UK banks means you can upload your bank statement and have transactions categorised without fiddling with column headers. Manual entry works for anyone who prefers to log transactions in real time. Quarterly submissions go directly to HMRC through the MTD API. The End of Period Statement and Final Declaration are built in.

That is the feature list. It is short because it is supposed to be.

One Decision Worth Making Now

April 2026 is the start of the MTD for Income Tax era for those earning above £50,000, and April 2027 for those above £30,000. The time to evaluate software is before the first quarterly deadline, not the week before it.

The vendor market will get noisier as the deadlines approach. More products will appear, more free trials will be offered, and more complexity will be marketed as capability. The electrician who opened this piece does not need capability. They need compliance, at a price that reflects their actual requirements.

Don't pay for a platform built for a fifty-person business. Find MTD software for small business that was actually designed for one person running their own trade.

People also ask

What is the best MTD software for a sole trader?

The best MTD software for a sole trader is the one that covers HMRC's requirements (digital records, quarterly submissions, End of Period Statement, Final Declaration) without charging for features you don't need. Look for plans that explicitly include MTD filing, offer simple expense categorisation, and have transparent annual pricing.

Do sole traders need accounting software for MTD?

Yes. Under MTD for Income Tax, sole traders must keep digital records and submit quarterly updates using HMRC-compatible software. Spreadsheets alone do not meet the requirement, though some bridging software can connect a spreadsheet to the MTD API if you prefer to keep records that way.

How much does MTD software cost for a small business?

Costs vary widely. Entry-level plans start from around £10-15 per month, but many restrict MTD functionality to higher tiers priced at £25-40 per month. Purpose-built sole trader MTD apps can cost significantly less because they exclude enterprise features that inflate the price.

When do small businesses have to use MTD software?

Sole traders and landlords earning above £50,000 must comply from April 2026. The threshold drops to £30,000 from April 2027. Below £30,000, HMRC has not yet confirmed a mandation date. Limited companies have a separate MTD for Corporation Tax timeline, which has not yet been finalised.
