MTD Software Year End Check: Can Your Clients File Their Return?

2026-10-12·The AI Ledger editorial team

MTD software that cannot file the year end tax return is now a live risk for UK practices. A Telegraph report published on 9 October 2026 found that 51 of 138 HMRC-recognised products for the self-employed cannot yet handle both quarterly updates and the end of year return. If a client is on one of them, the quarterly filing works, but the January return will need a second product or a switch.

TL;DR:

  • The Telegraph, citing analysis by LetCompliance, reported on 9 October 2026 that 51 of 138 MTD products for sole traders, and 44 of 128 for landlords, lack the full set of quarterly and year end features.
  • HMRC says features marked "under development" are expected to be ready before customers must submit their end of year return.
  • The first MTD for Income Tax tax return, for 2026 to 2027, is due by 31 January 2028, so the gap is a planning problem now, not a filing problem yet.
  • HMRC allows more than one product, but only one product for each separate submission, and the products must work together.
  • From 6 April 2027 HMRC expects around 1,077,000 more sole traders and landlords to come into scope, so the software you recommend this winter will carry a much larger client base.

What did the October 2026 software analysis find?

On 9 October 2026 The Telegraph reported an analysis by LetCompliance, a property management platform, of the products listed in HMRC's software finder. The headline figure: 51 of the 138 products available to self-employed users could not do both jobs that Making Tax Digital for Income Tax requires, sending quarterly updates and filing the end of year return.

The picture for landlords was similar. Of 128 products compatible with landlord requirements, 44 did not have the full range of tools. In the affected products, the year end return feature was listed either as "in development" or as not included at all.

The report quoted three views worth noting:

  • Erdem Volkan of LetCompliance said users could face extra complexity if they need a second product to complete their filing.
  • Emma Rawson of the Association of Taxation Technicians called the issue a "real area of concern" and warned that taxpayers who pick the wrong software could be surprised when they come to file.
  • An HMRC spokesperson said the Software Choices tool is updated regularly, and that where a feature is marked as under development, HMRC expects it to be ready before customers must submit their end of year return.

For a practice, the useful reading is narrow. Nothing here says quarterly filing is failing. It says roughly a third of listed products are, today, half a solution, and the half that is missing is the one that carries the tax liability.

What must MTD software do at the end of the tax year?

HMRC's guidance on finding compatible software sets out two separate jobs. Software must let users send quarterly updates, which HMRC describes as summaries of self-employment and property income and expenses, not tax returns. It must also let users submit the tax return by 31 January following the tax year, and report other income such as pensions or partnership profit.

The second job is the harder one. HMRC's page on submitting your tax return explains that HMRC adds some income itself, including PAYE employment income, pensions and CIS deductions, which the taxpayer must check. Other items, including savings interest, partnership profit shares and dividends, must be added in the software before the return is submitted.

That means year end software has to handle:

  1. The final figures for each self-employment and property income source, including any accounting and tax adjustments.
  2. Income from outside the quarterly regime, such as dividends and savings interest.
  3. Reliefs and claims that previously sat on the Self Assessment return.
  4. The calculation, its confirmation and the submission itself.

A bookkeeping app built around bank feeds and receipt capture can do the quarterly job well and still have no route for items 2 to 4. That is the gap the October analysis describes.

Pro Tip: When you assess a product, ask the vendor to show a full year end submission in a test account, including dividends and a partnership share. A feature list that says "tax return" is not the same as a workflow your team can run in January.

How do you check whether your MTD software can file the tax return?

HMRC's software finder asks a few questions and returns a personalised list, and it shows which features a product supports and which are still being built. HMRC removed the separate list of products in development on 13 July 2026, because those products now appear in the finder itself. Start there, then confirm with the vendor.

A practical check for each product your clients use:

  1. Search the finder by product name, not by category, and note every feature marked as under development.
  2. Check both income types. A product can be complete for self-employment and incomplete for property income, which matters for clients who are both sole traders and landlords.
  3. Check the agent features. HMRC lists support for multiple agents as a feature to consider, and only a client's main agent can submit the return through MTD software.
  4. Ask the vendor for a written date for any year end feature still in development, and record it against the client.
  5. Recheck in spring 2027. HMRC says the finder is updated regularly, so a status you record in October is a snapshot, not a guarantee.

Pro Tip: Keep the result in your practice management system as a field on each client record, with the date you checked. When the vendor ships the feature, you can filter for every affected client in one step rather than rediscovering the problem in December 2027.

Which tools in the directory fit an MTD workflow?

The AI Ledger does not certify MTD compliance; HMRC's finder is the authority on that. What the directory can do is show which tools play which role in an MTD workflow, with independent scores, published prices and the date each listing was last verified. Every tool below was last verified on 10 October 2026.

Two points from the editor verdicts stand out. TaxCalc is described as "a safe core choice" for UK compliance with little of the AI automation newer tools promise, which for a year end tax return is arguably the right trade. Briefcase is described as promising, with the advice to trial it on Xero clients before moving anyone to its own ledger. For Sage users, Sage Copilot (an editor score of 4 out of 5) is included in Sage Accounting with UK VAT and MTD help, though it is no use for Xero or QuickBooks books.

You can browse the wider set in the tax prep category, or put two candidates side by side on the compare page.

How should a practice handle clients split across two products?

HMRC permits more than one product. Its guidance says you can only use one product for each separate submission you need to make to HMRC, and if you use several products they must work together. So a client can keep a bookkeeping app for quarterly updates and have the practice file the return in tax software, provided the handover is clean.

A workable split looks like this:

  • Quarterly updates stay in the client's ledger or capture tool, where the digital records live.
  • The year end return is prepared in practice tax software, where the team adds adjustments, other income and reliefs.
  • One named owner in the practice is responsible for confirming that the fourth quarterly update and the return agree.

HMRC's quarterly updates guidance is relevant here. Updates are cumulative, each covering the tax year to date, and if records change after the fourth update you may need to resend that update before making tax adjustments. With two products in play, that resend is the step most likely to be missed.

Pro Tip: For clients on a product whose year end feature is still in development, price the January work as if you will be using your own tax software. If the vendor ships on time, the client gets a pleasant surprise; if not, your fee already covers the extra step.

What deadlines and penalty rules should you plan around?

The dates are set out on GOV.UK and do not depend on any vendor's roadmap.

  • Quarterly updates under standard update periods are due on 7 August, 7 November, 7 February and 7 May, each covering 6 April to the end of the quarter.
  • The tax return is due by 31 January after the end of the tax year. For 2026 to 2027, the first year of mandatory MTD for Income Tax, that is 31 January 2028.
  • The next cohort joins on 6 April 2027. In its October reminder to landlords, reported by Landlord Today on 6 October 2026, HMRC said around 1,077,000 more sole traders and landlords with qualifying income over £30,000 will need compatible software from that date, with the threshold falling to £20,000 from April 2028.

On penalties, HMRC's penalties guidance explains that late submission penalties are points based. While volunteering, each late return earns a point and a £200 penalty applies at 2 points. For those required to use MTD for Income Tax from 2027 to 2028, late quarterly updates also earn points, and the threshold rises from 2 points to 4.

The timing matters for software choice. A client joining in April 2027 will send six quarterly updates before their own first MTD return is due on 31 January 2029. That is a long time to go before discovering the product they chose cannot finish the job.

Why does independent evidence matter when choosing MTD software?

The October analysis shows the limit of a "recognised by HMRC" badge. Recognition tells you a product can make at least one valid submission. It does not tell you whether it makes every submission your client needs, how well it does so, or what it costs once introductory discounts end.

Vendor pages are written to win the sale, and a feature "coming soon" reads much like a feature available now. Independent editor scores, written verdicts that name the weaknesses, and a last verified date on every listing give you a second view, one with no stake in which product you choose. The AI Ledger's scores are editorial and are not affected by any commercial relationship with vendors.

Use the full directory alongside HMRC's finder: the finder for what a product is permitted to submit, the directory for how well it fits a practice and what it really costs.

Realistic expectations: software marked under development

HMRC expects features marked under development to be ready before the first returns are due, and many will be. Plan as if some will not: know which clients depend on an unfinished feature, and have a tested fallback in your own tax software before December 2027.

Find your next MTD software tool through The AI Ledger

If you are reviewing the products your clients use before the April 2027 cohort arrives, start with the tax prep category for practice tax software, then use the AI Ledger finder to narrow the field by practice size, ledger and budget. Each listing carries an editor score, a written verdict and the date it was last checked, so you can shortlist quickly and spend your demo time on the year end workflow that matters.
