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

What "HMRC-Recognised" Actually Means

HMRC maintains a list of software that is approved 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 approved providers.

QuickBooks: Comprehensive but Expensive

QuickBooks Self-Employed and QuickBooks Online both support MTD for VAT and Income Tax. The full QuickBooks Online (Simple Start tier) costs around £14–22/month depending on the current promotion. 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. Pricing is around £19/month (discounted if you bank with NatWest, RBS, or Mettle). It has a clean interface, good project tracking, and solid self-assessment support.

The monthly subscription model means you pay £228/year regardless of how many tax returns you file. For a sole trader who files quarterly VAT returns and an annual self-assessment, that works out at roughly £45 per filing, considerably more than per-use alternatives.

Xero: Enterprise Tool Used by Small Businesses

Xero is technically excellent and widely used by UK accountants. The Starter tier is around £15/month, but it has transaction limits that most active businesses quickly exceed, pushing users onto the Standard tier at £28/month.

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 Accounting: HMRC's Own Preferred Partner

Sage has been closely involved with HMRC's MTD rollout and offers Sage Accounting Start at around £15/month. It covers MTD for VAT and is extending to Income Tax. Sage has the advantage of deep HMRC integration and strong customer support.

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 £3.99 per filing, 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 per year plus an annual self-assessment and four VAT returns (nine filings total), the annual cost would be £35.91, compared to £180–336/year for monthly-subscription alternatives.

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, End of Period Statement, and 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 who join before 500 users 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.

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 from April 2026: 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 £15–28/month.

Regardless of which software you choose, the most important step is to choose something and start using it. The longer you leave it, the harder the transition will be when April 2026 arrives.
