Making Tax Digital 2026: 20% of Micro-Businesses Unaware of Deadlines

Making Tax Digital (MTD) is HMRC's long-term programme to modernise the UK tax system by requiring digital record-keeping and regular digital submissions. While MTD for VAT has been mandatory since 2019 for VAT-registered businesses, the major shift in 2026 targets Income Tax Self Assessment (ITSA) for sole traders, landlords, and partnerships. From 6 April 2026, those with qualifying gross income over £50,000 from self-employment and/or property must keep digital records, use MTD-compatible software, and submit quarterly updates instead of annual paper or manual returns. Recent surveys and expert commentary suggest awareness remains low among smaller operators—potentially around 20% of micro-businesses (very small sole traders or landlords with modest income) unaware of the changes or deadlines. This article explains the 2026 rollout, key deadlines, who it affects, penalties, and practical steps to prepare, especially for micro-businesses in the UK.

What is Making Tax Digital for Income Tax (MTD ITSA)?

MTD ITSA requires affected taxpayers to:

• Maintain digital records of income and expenses using HMRC-recognised software (e.g., QuickBooks, Xero, FreeAgent, or apps like GoSimpleTax).
• Submit quarterly summary updates (not full returns) to HMRC via the software.
• Provide an End of Period Statement (EOPS) and Final Declaration annually.
• Pay tax as usual (by 31 January following the tax year, with payments on account if applicable).

The goal: reduce errors, improve cash-flow visibility, and cut the tax gap. Unlike VAT MTD (which applies regardless of turnover if VAT-registered), ITSA MTD is phased by income thresholds.

Key Deadlines and Thresholds for 2026

• 6 April 2026 — MTD ITSA becomes mandatory for sole traders, landlords, and partnerships whose combined qualifying gross income (self-employment profits + UK property income) exceeded £50,000 in the 2024-25 tax year. From this date, digital records must be kept, and quarterly updates begin for the 2026-27 tax year.
• Quarterly Update Deadlines (for 2026-27 tax year):
  • 6 April to 5 July → Submit by 7 August 2026
  • 6 July to 5 October → Submit by 7 November 2026
  • 6 October to 5 January → Submit by 7 February 2027
  • 6 January to 5 April → Submit by 7 May 2027
• 31 January 2027 — Final Self Assessment tax return deadline under the old system (for 2025-26 tax year).
• 31 January 2028 — Pay tax for 2026-27 tax year (with any payments on account).

Future Phases

• From 6 April 2027: Threshold drops to £30,000 (based on 2025-26 income).
• From 6 April 2028: Further to £20,000 (plans subject to legislation).

Micro-businesses (often sole traders with income below £50,000) are not yet mandated in

2026 but should prepare as thresholds lower—many will enter scope soon.

Why 20% of Micro-Businesses Remain Unaware

Surveys and advisor feedback indicate uneven awareness:

• Many micro-businesses (e.g., freelancers, small landlords with 1-2 properties) operate informally or use basic spreadsheets/paper records.
• HMRC letters notifying affected individuals (sent late 2025) reach higher earners first; lower-income groups may miss or ignore communications.
• Experts note "two camps": proactive users of software vs. those avoiding change. Low awareness risks non-compliance when thresholds drop.
• Common misconceptions: "It only affects big businesses" or "VAT rules apply to me already" (MTD ITSA is separate).

This gap is concerning—non-preparation leads to rushed compliance, higher costs, or penalties.

Penalties and Reliefs in 2026-27

A points-based penalty system applies (similar to VAT MTD):

• Late submissions earn points; thresholds trigger fines (£200 initial, escalating).
• For 2026-27 (first year), no late filing penalties on quarterly updates (grace period), but points still accrue, and annual declaration penalties apply.
• Late payment penalties remain standard.

How to Prepare: Steps for Micro-Businesses and Sole Traders

1. Check Eligibility — Use HMRC's online tool to confirm if over £50,000 (or approaching lower thresholds).
2. Choose Compatible Software — Select from HMRC's list (free options like spreadsheets with bridging software exist, but paid apps offer better integration).
3. Set Up Digital Records — Start tracking income/expenses digitally now (even if not yet mandated) for smooth transition.
4. Join MTD Early (Voluntary) — Test the system before mandatory date; no penalties for early adopters.
5. Budget for Costs — Software fees (£10-50/month typical), plus potential accountant support.
6. Seek Advice — Consult accountants, use free HMRC webinars, or resources from FSB/ICAEW.

Frequently Asked Questions (FAQs)

1. Who must start MTD ITSA on 6 April 2026? Sole traders, landlords, and partnerships with qualifying income over £50,000 in 2024-25.

2. Do micro-businesses under £50,000 need to comply in 2026? No—but prepare now, as threshold drops to £30,000 in 2027 and £20,000 in 2028.

3. What software do I need? HMRC-recognised MTD-compatible tools (e.g., QuickBooks, Sage, Xero); bridging software for spreadsheets.

4. Are there penalties in the first year? No late filing penalties

on quarterly updates for 2026-27 (grace period), but points accrue.

5. How do quarterly updates work? Submit income/expense summaries every 3 months via software; no full accounts needed quarterly.

6. Does MTD apply to limited companies? No for Income Tax (yet); corporation tax MTD not scheduled for 2026.

7. What if I'm already using MTD for VAT? Separate rules—MTD ITSA adds quarterly income updates if over threshold.

8. Can I still use an accountant? Yes—many agents handle MTD submissions; discuss fees early.

9. Where can micro-businesses get free help? HMRC guidance, GOV.UK tool, webinars, or organisations like FSB.

10. Why is awareness low among micro-businesses? Many operate simply, miss notifications,

or assume it doesn't apply until lower thresholds.

The 6 April 2026 deadline for MTD ITSA marks a significant digital shift for higher-earning sole traders and landlords, with quarterly digital reporting replacing annual Self Assessment for many. While micro-businesses under £50,000 are not yet required, low awareness (potentially 20% or more unaware) risks future compliance issues as thresholds fall. Start preparing today: check your income, explore software, and build digital habits. Early action avoids stress, penalties, and last-minute costs.
