Best MTD-Compatible Tax Software for UK Sole Traders in 2026

What "HMRC-Recognised" Actually Means

HMRC maintains a list of software that is recognised for MTD submissions. To appear on this list, a provider must have passed HMRC's technical testing and demonstrated that their software can submit valid MTD updates via the HMRC API. Any software not on this list cannot be used for MTD, no matter how good it is otherwise.

Being on the HMRC-recognised list does not mean HMRC endorses the software or guarantees its quality. It means the technical interface works correctly. Always check the HMRC software list for the most current recognised providers.

QuickBooks: Comprehensive but Expensive

QuickBooks offers MTD on every plan. Sole Trader Plus is £10 a month plus VAT (£144 a year including VAT), and Simple Start, the first plan with its VAT tools, is £16 a month plus VAT (£230 a year including VAT), both at the regular price once the 90% off introductory offer ends. Prices from QuickBooks' own pricing page on 30 September 2026. The feature set is broad (bank feeds, invoicing, mileage tracking, payroll add-on), but for a sole trader who just needs MTD compliance and basic bookkeeping, it is significant overkill.

QuickBooks is at its best for businesses with employees, inventory, or complex reporting needs. Pure sole traders often find they are paying for a large number of features they never use.

FreeAgent: Popular with Freelancers, Pricey

FreeAgent has been a popular choice for UK freelancers and contractors for many years, and it supports MTD fully. Its Sole Trader plan is £19 a month or £190 a year plus VAT, and free if you bank with NatWest, RBS, Ulster Bank or Mettle. It has a clean interface, good project tracking, and solid self-assessment support.

Paid annually, that is £190 a year plus VAT (£228 including it), regardless of how many tax returns you file. A VAT-registered sole trader in MTD for Income Tax files four quarterly updates, four VAT returns and a final declaration, so that works out at roughly £21 per filing before VAT, considerably more than per-use alternatives. Most VAT-registered traders can reclaim the VAT; those on the Flat Rate Scheme usually cannot, so for them it is £228.

Xero: Enterprise Tool Used by Small Businesses

Xero is technically excellent and widely used by UK accountants. Its entry plan, Ignite, went up from £16 to £18 a month plus VAT on 1 September 2026, which is £259 a year including VAT. It limits how many invoices and bills you can raise, so busier businesses move up to a more expensive plan.

Xero is best suited to businesses that have an accountant managing their books: the interface is designed with professional users in mind. For self-managing sole traders, the learning curve and monthly cost are unlikely to be justified.

Sage: A Free Plan for Sole Traders Without VAT

Sage is one of the longest-established names in UK accounting software. For sole traders who are not VAT registered it has two plans, both marked Making Tax Digital ready: Sole Trader Free, which limits you to one bank account, five sales invoices a month and 25 auto-categorised transactions, and Sole Trader at £7 a month plus VAT after an introductory offer (£101 a year including VAT). Prices from Sage's own pricing page on 30 September 2026.

The software is reliable but conservative in design. It does not have the modern UX of newer entrants, but it does everything required for compliance safely and consistently.

FileThat: Built for MTD, Per-Filing Pricing

FileThat is a newer entrant designed from the ground up for the MTD era. Rather than a monthly subscription, it charges per submission, between £3.99 and £5.99 depending on your own income, meaning you only pay when you actually submit something to HMRC. New accounts receive 4 free credits on sign-up.

For a sole trader filing four quarterly MTD updates and four VAT returns, the annual cost is £31.92 on the lowest band and £47.92 on the highest. The final declaration is free, so it is eight paid submissions rather than nine. Subscriptions that also file VAT returns cost several times that: FreeAgent at £190, QuickBooks Simple Start at £192 and Xero Ignite at £216 a year, plus VAT, which most VAT-registered traders can reclaim (not usually on the Flat Rate Scheme).

FileThat includes digital record keeping with bank statement upload and AI-assisted transaction extraction, invoice generation, receipt management, mileage tracking, and the full MTD submission chain: quarterly updates, VAT returns, and the Final Declaration. It is designed specifically for UK sole traders and landlords.

The trade-off: it is a newer product with a smaller user base than the established players. Early adopters, the first 500 to connect to HMRC, lock in the £3.99 price permanently. It will not increase for them even as the product adds more features.

Which Should You Choose?

If you have an accountant who already uses Xero or QuickBooks: use whatever integrates with their workflow. The convenience of your accountant having direct access to your books usually outweighs the cost difference. See whether you need MTD software if you have an accountant.

If you manage your own books: the key question is how many filings you make per year. Under 12 filings per year, FileThat's per-filing model is likely cheaper than any monthly subscription. Over 12 filings, compare directly.

If you are VAT-registered and above the MTD ITSA threshold: you will be making at least 9 HMRC submissions per year. At that volume, pricing matters, and a per-filing model is significantly cheaper than subscriptions that cover VAT as well, such as FreeAgent at £190, QuickBooks Simple Start at £192 or Xero Ignite at £216 a year plus VAT. The cheapest MTD software page sets them side by side. Sage's cheaper plans are for traders who are not VAT registered.

Regardless of which software you choose, the most important step is to choose something and start using it. The longer you leave it, the more there is to catch up on at the next deadline.
