Best MTD Software for Sole Traders 2026: An Honest Buyer's Guide
An honest, no-hype comparison of MTD ITSA software for UK sole traders in 2026 — Xero, QuickBooks, FreeAgent, Coconut, Untied and bridging tools. Criteria, prices and who each suits.
Quick answer: The "best" MTD software is the one that is on HMRC's compatible-software list, fits how you actually work, and you'll keep using all year. For most sole traders that means a low-cost platform (roughly £7–£15/month) with good bank feeds, a usable mobile app and the ability to file both your quarterly updates and your final declaration. Prices and HMRC recognition change often, so always check your obligations with our MTD scope checker and confirm any tool against HMRC's official list before you buy.
If you're a sole trader trying to choose MTD software in 2026, you've probably noticed that most "best software" lists are really just affiliate rankings. This one isn't. Below are the criteria that genuinely matter, an honest comparison of the main options, and a plain note on where our own platform, Ledgers, does and doesn't fit yet.
First, do you even need it?
Making Tax Digital for Income Tax (MTD ITSA) became mandatory from 6 April 2026 for people whose qualifying income is over £50,000. Qualifying income means your gross turnover from self-employment plus any property income — it does not include salary, dividends, interest or pensions. If you're in scope, you must keep digital records in HMRC-compatible software and file four quarterly updates plus a final declaration each year.
One myth worth killing early: "HMRC-recognised" only means a product is technically compatible with HMRC's systems. It is not an endorsement, a quality score, or a guarantee the software is any good. Always cross-check against HMRC's official "find compatible software" tool — and if you're unsure whether you're even mandated yet, run the numbers through our MTD scope checker.
The criteria that actually matter
When you strip away the marketing, sole traders should weigh up seven things:
- HMRC-recognised for MTD ITSA — non-negotiable. If it can't file your quarterly updates and final declaration, it's not MTD software.
- Price — most sole-trader plans land between £7 and £15 a month. Watch for "introductory" pricing that jumps later.
- Ease of use — you'll be in this thing every quarter. If it feels like enterprise accounting software, you'll avoid it.
- Bank feeds — Open Banking connections that pull transactions in automatically save hours and cut errors.
- Files the final declaration — some tools handle quarterly updates but not the year-end Self Assessment step. Check this carefully.
- Mobile app — if you work on the move, a strong app matters more than desktop polish.
- Support — when a deadline looms, can you actually reach a human?
The main options compared
The table below is illustrative. Pricing and HMRC recognition change frequently — verify both before buying.
| Software | Typical price (verify) | Bank feeds | Files final declaration | Mobile | Best for |
|---|---|---|---|---|---|
| Xero | ~£7/mo "Simple", ~£16/mo "Ignite" | Yes | Via plan/partner | Good | Growing sole traders who may scale up |
| QuickBooks Sole Trader | ~£10/mo | Yes | Yes | Strong app | Mobile-first traders who want a tidy app |
| FreeAgent | Free with NatWest/RBS/Ulster/Mettle, else ~£19/mo | Yes | Yes (incl. Self Assessment) | Good | Customers of the qualifying banks |
| Sage | Varies by plan | Yes | Via plan | Available | Those wanting an established brand |
| Coconut | Free tier (limits); paid up to ~£14/mo | Yes | Check tier | Mobile-first | Simple sole traders (paid tier needs a bank switch) |
| Untied | Free tier (limits); paid up to ~£14/mo | Yes | Check tier | Mobile-first | Lightweight record-keeping |
| Bridging software (e.g. VitalTax) | ~£30/year | N/A (uses your spreadsheet) | Submits updates | N/A | Confident spreadsheet users |
| Ledgers | New platform — see below | Open Banking | Built for MTD | App planned | Sole traders wanting "books that keep themselves" |
A couple of honest caveats on the table. FreeAgent is genuinely free only if you bank with NatWest, RBS, Ulster Bank or Mettle — otherwise it's one of the pricier options at around £19/month. Coconut's paid tier has historically required switching your business banking to them, which is a bigger commitment than installing an app. And bridging software like VitalTax doesn't replace a spreadsheet — it bolts on to let you submit, which is great if you love spreadsheets and terrible if you wanted to stop wrestling with them.
Who each option suits
You want one tool that grows with you: Xero or QuickBooks. Both are full platforms with strong ecosystems. Xero's entry "Simple" plan is cheap; its "Ignite" tier costs more but adds room to grow. QuickBooks is often praised for its mobile app.
You bank with NatWest, RBS, Ulster or Mettle: FreeAgent is hard to beat because it's free for you and files Self Assessment. For everyone else, weigh that ~£19/month against cheaper rivals.
You're a simple, mobile-first trader: Coconut or Untied. Both have free tiers with limits and lightweight paid tiers. Just check whether the free tier actually covers MTD filing, and read the bank-switching small print on Coconut.
You love spreadsheets and don't want to leave them: Bridging software (around £30/year) keeps your spreadsheet and adds the HMRC submission layer. If you'd rather move off spreadsheets entirely, see our guide on moving from spreadsheets to MTD software.
Where Ledgers fits — honestly
Ledgers is a new UK platform built specifically for MTD ITSA — the idea is "books that keep themselves," with Open Banking feeds doing the heavy lifting so quarterly updates aren't a scramble.
Two things we'll say plainly. First, we're new, so we don't have the years of reviews that Xero or QuickBooks do — that's a fair reason for some people to wait. Second, and most importantly: any software, including Ledgers, must appear on HMRC's recognised list before it can legally file your MTD returns. Check that list before committing to us or anyone else. If your priority is a battle-tested brand today, an established platform may suit you better right now; if you want a tool designed from scratch around the 2026 rules, see how Ledgers works.
Frequently asked questions
Does "HMRC-recognised" mean HMRC recommends the software? No. It only means the product is technically compatible with HMRC's systems. It's not a quality rating or an endorsement. Always check HMRC's official compatible-software list and judge the tool on its own merits.
What's the cheapest way to be MTD-compliant as a sole trader? If you bank with NatWest, RBS, Ulster or Mettle, FreeAgent is free. Otherwise, bridging software (around £30/year) is often the lowest cash cost if you're happy keeping a spreadsheet. Full platforms typically run £7–£15/month.
Will my software file both the quarterly updates and the final declaration? Not always. Some tools handle quarterly updates but stop short of the year-end final declaration. Confirm this specific capability before you buy — it's the step that completes your tax position.
I'm under £50,000 — do I need any of this? Not for the 6 April 2026 mandate, which applies to qualifying income over £50,000. Thresholds are due to lower in later phases, so it's worth checking your position with our scope checker.
Can I just keep my spreadsheet? Yes — if you add HMRC-recognised bridging software to submit from it. You keep the spreadsheet you know and gain the ability to file digitally.
