1.08 Million Sole Traders Face April 2027 Digital Tax Deadline as HMRC Issues Six-Month Warning

Around 1.077 million sole traders and landlords earning more than £30,000 annually must adopt digital tax record-keeping systems by 6 April 2027, according to HMRC^[1]. The revenue authority issued its warning on 5 October 2026, marking the six-month countdown to mandatory compliance with Making Tax Digital (MTD) for Income Tax.

The deadline represents the second phase of MTD rollout for the self-employed. Sole traders and landlords earning over £50,000 have been using the service since April 2026, with their second quarterly update due on 7 November 2026^[1].

What Changes on 6 April 2027

From that date, affected sole traders and landlords will be required to create digital records and use compatible software to send HMRC quarterly updates of their income and expenses^[1]. The quarterly updates are not additional tax returns, but short summaries of business activity.

The £30,000 threshold applies to gross income from self-employment and property before any tax allowances or expenses are deducted^[1]. Those meeting the threshold must complete their tax return through MTD-compatible software in addition to submitting quarterly summaries.

Craig Ogilvie, HMRC's Director of Making Tax Digital, said: "Hundreds of thousands of sole traders and landlords are already successfully using Making Tax Digital and now it's time for the next group to get ready. Signing up now means you can prepare and familiarise yourself with the process before it becomes mandatory next April."^[1]

Timeline and Enforcement Risk

HMRC is urging affected businesses to sign up on GOV.UK and begin preparing immediately^[1]. Early sign-up allows customers to verify their MTD details and select software that suits their business needs. Tax agents can also register clients through the same portal.

The threshold will decrease further in future years, bringing more self-employed individuals into the digital tax regime^[1]. HMRC's 5 October announcement, timed at the six-month mark, signals an escalation from guidance to enforcement mode.

The digital record-keeping helps sole traders "save hours previously spent gathering information at tax return time, helping them spend more time focusing on their business and avoiding the last-minute rush every January"^[1].

Software Requirements

Compatible software must be able to create and preserve digital records of income and expenses, and submit quarterly updates and final tax returns to HMRC electronically. HMRC advises customers to choose compatible software; the 5 October announcement did not specify approved vendors or pricing^[1].

Sole traders currently using spreadsheets or paper records will need to transition to digital systems.

UK Business Register Context

Separate from the MTD announcement, Companies House data^[2] shows the UK company register contained 5,403,344 active companies as of October 2026, with 15,654 new incorporations in the seven days to 9 October 2026. These economy-wide figures reflect all registered companies and do not specifically indicate sole trader or landlord activity related to the MTD threshold.

The register's top sectors by company count include real estate letting and operating (SIC 68209: 448,093 companies), management consultancy (SIC 70229: 276,635 companies), and real estate buying and selling (SIC 68100: 276,349 companies)^[2]. London accounts for 1,054,811 registered companies across all sectors, followed by Manchester (104,414) and Birmingham (92,612)^[2].

These register statistics describe the entire UK business population and do not indicate which businesses fall within the MTD £30,000 threshold or their current state of digital readiness. Many sole traders operate as unincorporated businesses and do not appear in the Companies House register.

Next Steps for Affected Businesses

Sole traders and landlords should verify whether their gross income exceeds £30,000 before deducting allowances or expenses. Those above the threshold should sign up for Making Tax Digital on GOV.UK, select compatible software, and begin creating digital records before 6 April 2027^[1].

Agents representing multiple clients should begin the registration process early to avoid bottlenecks as the April deadline approaches. Signing up early means customers can make sure their MTD details are correct and have time to choose software that works best for them^[1].
