MTD Software Comparison UK: What the Price Tags Hide
Comparing MTD software UK? Before you subscribe, find out what the headline prices hide, which features you actually need, and what sole traders are overpaying for.
April 2026 is closer than it looks, and the MTD software industry knows it. If you have searched "mtd software comparison uk" in the last few months, you have likely landed on review sites that are, let's say, generously sponsored by the very products they rank. This post is not that.
What follows is an honest look at what the main MTD-compliant software options actually cost sole traders, what those costs buy you, and where the industry has quietly decided to charge a premium for features a plumber, electrician, or freelance designer will never use. The goal is not to hand you a league table. It is to help you stop paying for someone else's feature roadmap.
- MTD software pricing is almost always structured around small businesses, not sole traders. You pay for multi-user access, payroll, and inventory management you will never touch.
- The HMRC-approved software list has over 50 products on it. Fewer than a handful are built specifically for sole traders doing quarterly submissions.
- Hidden costs include VAT on subscriptions, annual price increases, and data-export fees if you want to leave.
- The quarterly submission MTD requires is genuinely simple. Your software should reflect that simplicity in its price.
- Comparing on monthly headline price alone is a trap. Compare on what you actually submit: income, expenses, and four quarterly updates per year.
Why the MTD Software Market Is Not Designed for You
Let's start with an uncomfortable fact. The UK accounting software market is dominated by products built for small limited companies: businesses with employees, VAT returns, stock control, and multiple bank accounts. Sole traders are a secondary audience, often served by a stripped-down "self-employed" tier that is still priced, and over-featured, relative to what MTD for Income Tax actually requires.
- MTD for Income Tax Self Assessment (MTD ITSA)
- HMRC's mandate requiring self-employed individuals and landlords to keep digital records and submit quarterly updates of income and expenses via HMRC-approved software, replacing the single annual Self Assessment return. Sole traders earning over £50,000 must comply from April 2026, with lower thresholds following in 2027 and 2028.
What does MTD for Income Tax actually require you to submit? Four quarterly updates per year, each containing a summary of your income and expenses for that three-month period. Then a final declaration at the end of the tax year. That is it. There is no invoice matching, no payroll run, no stock reconciliation. It is, at its core, a categorised list of money in and money out, sent to HMRC four times a year instead of once.
Now compare that to the feature sets of the products typically dominating MTD software comparison pages.
The Main Players: What You Are Actually Paying For
QuickBooks Self-Employed and QuickBooks Sole Trader
Intuit's QuickBooks has two tiers aimed at self-employed people in the UK. The Self-Employed plan has historically sat around £8 per month, rising after an introductory period. The Sole Trader plan, which is MTD-compliant, costs more.
The core features are mileage tracking, receipt capture, and tax estimates. These are genuinely useful. But QuickBooks is an American product, and it shows. The interface is cluttered with prompts toward features that apply to US tax law, and the UK-specific MTD submission pathway requires navigating menus that feel like afterthoughts. If you have already read our comparison of FreeAgent vs QuickBooks Self Employed: Stop Paying for Features You'll Never Use, you will recognise the pattern.
Critically, Intuit has a history of price increases. QuickBooks raised UK subscription prices multiple times between 2021 and 2024. When you sign up at a promotional rate, build that in.
Xero
Xero is excellent software. It is also software built for limited companies and growing businesses. Its cheapest plan starts around £16 per month (at 2024 pricing), and it caps the number of invoices you can send. For a sole trader turning over £60,000 a year who sends twenty invoices a month, that cap bites almost immediately, forcing you up to a more expensive tier.
Xero's MTD submission feature works well. Its open API and bank feed integrations are best-in-class. But you are paying for infrastructure designed for a five-person agency, not a self-employed electrician reconciling materials purchases and labour income. Our post on QuickBooks vs Xero UK Sole Trader: Are You Overpaying? digs further into this.
FreeAgent
FreeAgent is free if you bank with NatWest, Royal Bank of Scotland, or Ulster Bank, which is worth knowing if your business account sits with one of those banks. For everyone else, it costs around £19 per month after the introductory period.
FreeAgent is genuinely good for sole traders. It handles MTD submissions, Self Assessment estimates, and expense categorisation in a way that makes sense without an accounting degree. The downside is that the free tier is bank-dependent, and if you ever switch banks, you start paying full price. That is not a transparent model.
Sage Accounting
Sage is the incumbent. It has been selling accounting software to UK businesses since the 1980s and it has the pricing to match its legacy status. Sage Accounting starts at around £15 per month, but the MTD-specific features that actually matter are in higher tiers. Sage also pushes hard toward its payroll and HR add-ons in its interface, which is a lot of noise if you are a self-employed plasterer with no staff.
TapTax
TapTax is built specifically for the MTD submission use case. No payroll. No inventory. No invoicing suite. Just digital record-keeping, expense categorisation, and quarterly submissions to HMRC in a format that sole traders can actually understand. If you want to see what purpose-built looks like for this specific compliance requirement, Making Tax Digital App: What Your Phone Can Actually Do explains the practical difference.
The Hidden Costs Nobody Puts in the Comparison Table
Monthly price is the least important number in an MTD software comparison. Here is what to look for instead.
VAT on top
Most software pricing is shown excluding VAT. Add 20% to every figure you see. A £12 per month plan is actually £14.40. Over a year, that is £172.80, not £144. Small difference, but it compounds when you are comparing across several tools.
Introductory pricing cliffs
Many providers offer 50% or 90% discounts for the first three to six months. Xero, QuickBooks, and Sage all do this routinely. After the promotional period ends, prices jump. If you sign up for MTD compliance on a deal, calendar the date your price changes. You will often find you are on a more expensive plan than you expected twelve months later.
Data export and lock-in
This one matters enormously if you decide to switch. Some platforms make exporting your transaction history genuinely difficult. Others charge for it, or export in formats that no other tool can easily import. Before committing to any MTD software, ask yourself: if I want to leave in eighteen months, can I take my data with me, in a usable format, for free?
Add-on creep
Payroll. Receipt scanning powered by AI. Priority support. Advanced reporting. Tax advice via chat. Every software company in this space is looking for ways to sell you adjacent services. MTD compliance is the entry point. The upsell is the business model. Budget accordingly.
What a Sole Trader Earning £65,000 Actually Needs
Let's make this concrete. Say you are a self-employed plumber, sole trader, earning around £65,000 gross per year. You have a business bank account and a personal account. You spend money on tools, van fuel, materials, insurance, and subcontractors on larger jobs. You send invoices. You do not employ anyone.
For MTD compliance, here is what you need from software:
- A way to connect or import your bank transactions
- Expense categorisation (HMRC has specific categories; your software must map to them)
- Quarterly submission to HMRC via the API
- A running estimate of your tax liability so you can plan your payments on account
- A final declaration at year end
That is the list. Payroll integration: irrelevant. Multi-currency: irrelevant. Project profitability tracking: nice but not required. Stock management: not applicable.
If a product charges you £25 per month and twenty of that is funding features outside the list above, you are subsidising other customers' software needs.
You can also use our sole trader tax calculator to sanity-check your quarterly estimates against what the software tells you, without relying entirely on a black box.

The Feature You Should Actually Test Before Subscribing
Every MTD software product offers a free trial. Most sole traders use the trial to check that the dashboard looks clean and the bank feed connects. Almost nobody uses the trial to test the one thing that matters most: the quarterly submission flow.
Before you commit, go through the motion of submitting a quarterly update, even with dummy data. Ask yourself:
- How many clicks does it take from categorised transactions to submitted update?
- Does the software clearly tell you what HMRC has received and when?
- If a submission fails (wrong figures, connectivity issue), does the software explain why in plain English or in an error code?
- Can you amend a submitted quarter without calling support?
If the submission pathway is buried in menus designed for accountants, that is the product telling you something about who it was built for.
The HMRC Approved Software List: A Word of Warning
HMRC publishes a list of MTD-approved software on its website. Being on that list means the software can technically connect to HMRC's API and submit quarterly updates. It does not mean the software is well-designed, fairly priced, or appropriate for a sole trader.
The approved list includes enterprise-level products that charge hundreds of pounds per month. It includes products aimed at accountancy firms managing hundreds of clients. It includes bridging tools that, as we explored in MTD Bridging Software: A Stopgap or a Trap?, may create more administrative work than they save.
Being on the HMRC list is a compliance credential, not a quality signal. Treat it as the minimum bar, not the recommendation.
Making the Right Call for Your Business
The right MTD software for a sole trader earning £65,000 is not the same as the right software for a three-person limited company with a VAT return due every quarter. The market conflates these audiences, often deliberately, because sole traders are numerous and the upsell opportunity is significant.
Here is a practical decision framework:
If you are a sole trader with straightforward income and expenses: Look for software built specifically for MTD ITSA submissions, not a cut-down tier of a product built for something else. Price should reflect the simplicity of what you are actually doing.
If you also send invoices and want to manage them in the same place: Check that the invoicing feature is included in the base price, not an add-on, and that it covers your volume without hitting a tier cap.
If you have a business bank account with NatWest, RBS, or Ulster Bank: FreeAgent is genuinely free and genuinely good. Use it.
If you are currently using a spreadsheet and bridging software: The clock is ticking on that approach. HMRC's direction is toward full digital records, and bridging tools are not a long-term solution. The How to Set Up Making Tax Digital: A No-Nonsense Walkthrough is a practical starting point if you want to move across before you are forced to.
And before you finalise anything, cross-reference what the software tells you about your tax liability against an independent source. The Sole Trader Tax Calculator UK: What Most Get Wrong post explains why those in-app estimates sometimes mislead.
The Bottom Line on MTD Software Comparison UK
The search for MTD software comparison UK returns a lot of content written by people with a financial interest in where you click. The honest answer is that most sole traders are being sold software designed for businesses two or three times their complexity, at prices that reflect that complexity.
Four quarterly submissions per year is not a complicated task. The software you use to do it should not cost more per month than a tank of petrol or require a user manual. If the product you are considering feels like overkill, that instinct is probably correct.
We opened with the observation that April 2026 is closer than it looks. It is. But that does not mean you should panic-buy the first product a sponsored comparison site recommends. Take the free trials. Test the submission flow. Add up the real annual cost including VAT. And ask yourself whether you are paying for your compliance needs or for someone else's product roadmap.
