Making Tax Digital for Income Tax: What Sole Traders Earning £50k+ Must Do Now

Making Tax Digital (MTD) for Income Tax arrived on 6 April 2026 as, in the words of Simply Business, the biggest change to the UK tax system in decades. If you're a sole trader or landlord with gross turnover (not profit) above £50,000, you're now required to keep digital records and submit quarterly updates to HMRC rather than a single annual Self Assessment return.

Who's affected, and when

The rollout is phased by income threshold:

• £50,000+ gross qualifying income: mandatory from April 2026.
• £30,000–£50,000: mandatory from April 2027.
• £20,000–£30,000: mandatory from April 2028.

Gross income here means total turnover before expenses. Crucially, HMRC combines income across multiple sources — so a consultant earning £35,000 in freelance income plus £20,000 in rental income is already over the £50,000 threshold today, even though neither income stream alone would trigger MTD, according to Alto Accounting.

Limited companies are unaffected by this specific regime — they remain under Corporation Tax rules and outside MTD for Income Tax entirely, per Sage's guidance.

What you now need to do

• Keep digital records of income and expenses using MTD-compatible software — spreadsheets can qualify only if paired with "bridging software" that submits data in the right format.
• Submit quarterly updates to HMRC, moving the tax system closer to real time rather than one annual reconciliation.
• Still complete an End of Year declaration, similar in spirit to the old Self Assessment return, to finalise your tax position for the year.
• Note the first quarterly submission deadline for many affected sole traders and landlords for the 2026/27 tax year falls on 7 August 2026.

Checklist: getting MTD-ready

• Check your combined gross income across all self-employment and property sources — not just your main trade — against the £50,000 threshold.
• Choose MTD-compatible software now if you haven't already; HMRC provides a list of recognised software.
• Start digital record-keeping immediately, even mid-year, rather than waiting for your first quarterly deadline to catch up on months of paper receipts.
• Diary the quarterly deadlines for your specific accounting periods — missing updates can trigger the same points-based penalty system used for VAT.
• Watch for the HMRC sign-up service outage from 5pm Friday 10 July to 9am Monday 13 July 2026, when the MTD sign-up portal will be down for maintenance, per Tax Journal.
• Talk to your accountant now if you're close to the £50,000 threshold, since combined income across job types can push you over without you realising.

International comparison

Real-time digital tax reporting isn't unique to the UK. Australia has required Single Touch Payroll real-time reporting from employers for several years, while the US IRS has moved toward more frequent estimated tax reporting for self-employed individuals but has no equivalent mandatory quarterly digital submission regime for sole traders. The EU has pursued digital VAT reporting standards (e-invoicing) more aggressively than digital income tax reporting.
