436,000 Sole Traders and Landlords Complete First Making Tax Digital Submission

More than 436,000 sole traders and landlords have successfully submitted their first Making Tax Digital for Income Tax quarterly update for the 2026 to 2027 tax year, according to HM Revenue and Customs^[1]. Over 570,000 customers have now signed up to the service, marking an important milestone in HMRC's move to a fully digital tax system.

The figures, published on 12 August 2026, reveal strong early compliance momentum among the UK's self-employed population, with the first quarterly updates covering the opening three months of the tax year from April 2026^[1]. The submission data represents a 76% conversion rate from sign-ups to completed returns, suggesting that once registered, most sole traders and landlords are successfully navigating the new digital reporting requirements.

Mandatory Digital Record-Keeping Begins

Sole traders and landlords earning more than £50,000 have been required to keep digital records and send quarterly updates to HMRC since April 2026^[1]. The requirement marks the first phase of Making Tax Digital for Income Tax, which will eventually extend to all self-employed individuals and landlords regardless of income level.

Craig Ogilvie, HMRC's Director of Making Tax Digital, said: "It's fantastic to see so many sole traders and landlords successfully sending their first quarterly updates. This marks an important milestone in the move to a more modern tax system, with many customers telling us that the process is straightforward and works well through their chosen software."^[1]

Customers who have not yet sent their first quarterly update can do so now through their recognised software^[1]. In 2026 to 2027, there are no penalty points for late quarterly updates, giving businesses a grace period to adapt to the new regime.

HMRC to Begin Mandatory Sign-Ups in September

From September 2026, HMRC will begin signing up customers who should be using Making Tax Digital for the 2026 to 2027 tax year but have not yet done so^[1]. This process will happen in stages over the coming months, helping businesses meet their requirements.

HMRC is encouraging eligible businesses to sign up voluntarily before the mandatory process begins. Customers who sign up themselves can ensure their Making Tax Digital details are correct from the start and prepare in their own time, rather than waiting to be contacted by HMRC^[1].

The agency has published guidance and support materials on GOV.UK to help customers complete the sign-up process^[1].

Gap Between Sign-Ups and Submissions

The 134,000-customer gap between total sign-ups (570,000) and completed first submissions (436,000) highlights a common pattern in regulatory adoption: registration precedes actual compliance behaviour^[1]. This 23% non-submission rate among registered users may reflect several factors, including businesses still preparing their software integrations, delayed income recognition, or uncertainty about quarterly reporting obligations.

The absence of penalties for late quarterly updates in the first year appears designed to reduce this gap over time, allowing businesses to learn the process without immediate financial consequences. The policy mirrors HMRC's approach with Making Tax Digital for VAT, which also provided a soft-landing period during initial rollout.

UK Company Register Context

Across the broader UK company register, 5,563,777 companies are currently active^[2], with 14,596 new incorporations recorded in the seven days to 13 August 2026^[2]. These economy-wide statistics provide context for the scale of HMRC's digital transformation challenge: the 570,000 Making Tax Digital sign-ups represent roughly 10% of the active company population.

However, many sole traders and landlords operate as unincorporated businesses and therefore do not appear in Companies House records. The Making Tax Digital cohort likely represents a substantial portion of the UK's total self-employed population earning above the £50,000 threshold.

Forward-Looking Compliance

The 436,000 completed submissions signal that HMRC's digital infrastructure is handling the initial wave of quarterly reporting without major technical failures. The relatively high conversion rate from sign-ups to submissions suggests that software integrations are functioning as designed, and that accountancy practices and software providers have successfully prepared their client bases for the transition.

As the September 2026 mandatory sign-up process begins, the number of registered users is expected to increase substantially. The first-year penalty-free period will provide a critical window for HMRC and the software industry to identify and resolve any remaining friction points in the submission process before full enforcement begins in the 2027 to 2028 tax year.

The staged rollout approach - beginning with higher earners and expanding over time - mirrors the Making Tax Digital for VAT implementation, which began in 2019 and has since been extended to virtually all VAT-registered businesses. The Income Tax phase represents a significantly larger and more diverse taxpayer population, making early compliance data particularly important for forecasting future adoption patterns.
