Best MTD-Compliant Software for Sole Traders in 2026

Once you know your Making Tax Digital start date (check yours here if you haven't already), the next decision is which software to actually use. HMRC maintains a list of officially recognised options, but in practice, five platforms cover almost everyone: FreeAgent, Xero, QuickBooks, Sage, and Zoho Books. Here's how they actually differ, and which one fits which situation.

If I'm honest, choosing software was genuinely one of the things that pushed me to build this site in the first place. I noticed a lot of the big, popular sites and forums covering this always seem to push whichever provider happens to pay the highest commission — maybe that's just me being sceptical, but it's hard to unsee once you notice it. I've actually used and explored every platform on this list myself, and my honest view is that none of them is simply "the best" — it depends on you. Do you want quick, live information linked to your bank account, or do you just prefer one interface over another? All of them let you make manual adjustments and see exactly what will be submitted before it goes anywhere near HMRC, so it's worth trying a couple yourself rather than picking blind.

The quick comparison

FreeAgent — best if you already bank with the right provider

FreeAgent is built specifically around UK freelancers, contractors, and small limited companies, and it shows in the details: invoicing, expense tracking, and MTD submissions are all designed around how UK sole traders actually work, without the extra complexity aimed at bigger businesses.

The detail that changes the maths for a lot of people: FreeAgent is free for life if you hold a business account with NatWest, Royal Bank of Scotland, Ulster Bank, or Mettle — saving you up to £150 a year based on FreeAgent's lowest tariff. If you're choosing a business bank account anyway, this is a genuine reason to weigh it into that decision rather than treating banking and accounting software as separate choices. (See our guide on business accounts that bundle free MTD software.)

Where it falls short: it's not well suited to businesses with complex stock/inventory tracking, construction firms relying heavily on CIS deductions, or companies needing advanced multi-user permissions.

Xero — best if you work with an accountant

Xero is the most widely used cloud accounting platform in the UK, largely because of how well it plays with the wider ecosystem: unlimited users on every plan, and over 800 integrations with other business tools. If you already have (or plan to hire) an accountant or bookkeeper, Xero's ubiquity means they're more likely to already know it well.

It doesn't have a genuinely free tier, and it's arguably more software than a very simple sole trader needs — the strength shows up more as your bookkeeping gets more complex.

QuickBooks — best for keeping costs down as a self-employed person

QuickBooks (Intuit) has the lowest starting price of the paid options and is specifically strong for straightforward self-employed use — including GPS mileage tracking, which matters if a meaningful chunk of your expenses is vehicle-related. MTD support is solid across all its plans, not gated to a premium tier.

Sage — best for UK-specific compliance, and the strongest free option if you're not VAT-registered

Sage is the only one of the major platforms built specifically for the UK market rather than adapted from a global product, and it's a longstanding name UK accountants tend to trust. Its Sole Trader Free plan is genuinely free (not a time-limited trial) for non-VAT-registered businesses, and it's MTD-approved for quarterly submissions — making it one of the few real "free forever" options for a sole trader who doesn't already qualify for FreeAgent's bank-linked free tier. It also has a stronger payroll add-on than most competitors, worth knowing if you plan to hire.

Zoho Books — best if you want to start at zero cost with no strings attached

Zoho's free plan covers up to 1,000 invoices a year — enough for most sole traders just starting out — and includes MTD-relevant features like digital records with an audit trail, plus preparation for the specific Self Assessment forms (SA103F/SA103S) that self-employed income uses. Unlike Sage's free tier, it isn't restricted to non-VAT-registered businesses, and unlike FreeAgent's free route, it doesn't require you to bank with a specific provider.

The trade-off is ecosystem size — fewer UK accountants use Zoho day-to-day compared with Xero or QuickBooks, and its UK-specific compliance features are a bit newer than Sage's.

Which one should you actually pick?

• Already bank with NatWest, RBS, Ulster Bank, or Mettle? → FreeAgent, free — there's little reason to pay elsewhere unless you have a specific feature need.
• Not VAT-registered and want £0 cost with no bank strings attached? → Sage Sole Trader Free or Zoho Books — compare their free-tier limits against your invoice volume.
• Work with an accountant, or expect to soon? → Xero, for the ecosystem fit.
• Self-employed, cost-conscious, and drive a lot for work? → QuickBooks, for the low entry price and mileage tracking.
• Planning to hire staff soon? → Sage, for the payroll integration.

Whatever you land on, you're not on your own with it — there's a lot of support out there for all of these platforms, and they're all being improved constantly. One thing worth remembering, though: free isn't always free if it ends up costing you more time and effort than a paid option would have saved you. Try a couple, see what actually fits how you work, and go from there.
