Missing the 7 August 2026 Q1 deadline doesn't mean penalties: for 2026-27, HMRC won't issue penalty points for late quarterly updates. It still helps to understand who can be exempt from MTD and what counts as a reasonable excuse. If you're facing genuine difficulties - whether illness, software failures, or other circumstances beyond your control - you might qualify for relief or an exemption.

With 70 days until the Q1 deadline, many sole traders and landlords are wondering about their options. This guide explains the updated exemption criteria, how to apply for relief, and what happens if you file late without a valid excuse.

Who Qualifies for MTD Exemptions

HMRC recognises that not everyone can meet quarterly deadlines due to circumstances beyond their control. The main exemption categories are:

Digital Exclusions

You can apply for a digital exclusion if you genuinely cannot use digital services due to:

Digital exclusions are not automatic. You apply to HMRC (the exemption application process is on GOV.UK) and explain why it isn't reasonably practicable for you to use digital tools.

Gross Income Below Thresholds

You don't have to use MTD if your qualifying income is at or below the threshold. Qualifying income is your self-employment and property income combined, before expenses:

So £30,000 from freelancing plus £25,000 rent is £55,000 of qualifying income, which is in scope from April 2026.

Note: Once you're in MTD, you can only leave after your qualifying income has been below the threshold for three consecutive tax years.

Temporary Business Cessation

If you've permanently stopped trading or renting out property, you don't need to file further quarterly updates. However, you must still submit a final tax return covering the period up to when you ceased trading.

What Counts as Reasonable Excuse

HMRC's updated guidance clarifies what constitutes a reasonable excuse for late filing. These excuses can justify delays but must be applied for properly.

Illness and Health Issues

Serious illness affecting you or a close family member can excuse late filing. HMRC considers:

Minor illnesses lasting a few days typically won't qualify unless they occurred right before the deadline.

Technology and Software Failures

Computer or software problems can excuse late filing if:

This includes issues with your MTD software, computer hardware failures, or internet outages. However, you'll need evidence of the problem and your attempts to fix it.

Warning: HMRC service outages are handled differently. If HMRC's own systems prevent filing, this is automatically excused without needing to apply for relief.

Postal and Communication Delays

While MTD is digital-first, communication delays can still affect filing. Examples include:

Fire, Theft, or Flood

Natural disasters or crimes affecting your business records or equipment clearly qualify as reasonable excuses. You'll need evidence like police reports, insurance claims, or fire service reports.

How to Apply for Relief

The process for claiming relief depends on whether you're applying for an exemption or appealing a penalty after filing late.

Applying for Digital Exclusions

Apply for a digital exemption as early as you can, using the process on GOV.UK. HMRC will tell you if you're exempt, and until then you should keep to your obligations.

Evidence might include medical reports for disability claims, utility bills showing your address for remote location claims, or letters from religious leaders for faith-based applications.

Claiming Reasonable Excuse After Late Filing

If you've already missed a deadline, you can appeal any penalties by claiming reasonable excuse. You must:

  1. File your late quarterly update as soon as possible
  2. Wait for HMRC to issue penalty notices
  3. Appeal within 30 days of receiving the penalty notice
  4. Provide evidence supporting your reasonable excuse claim

Appeals are made online through your Government Gateway account or by calling HMRC's helpline.

Evidence You'll Need

Strong evidence is crucial for successful appeals. Gather:

What Happens If You Miss the Deadline Without Exemption

MTD uses a points-based system for late submissions rather than automatic fines.

How Late Submission Penalties Work

A late final declaration earns a point even in 2026-27, so the 31 January 2028 deadline still matters.

Late Payment

Paying tax late is separate: 3% of the unpaid tax at day 15, a further 3% at day 30, then 10% a year, plus interest at the Bank of England base rate plus 4%.

Note: Interest also accrues on unpaid tax from the original deadline, regardless of when you file. Late filing doesn't delay when tax is due.

Practical Steps If You're Struggling

If you're concerned about meeting the Q1 deadline, take action now rather than hoping for the best.

Assess Your Situation

First, determine if you actually need to file. Check our guide on whether you need MTD to confirm your obligations.

If you do need to file, review your progress. Our pre-submission checklist helps identify what's outstanding.

Address Common Issues Early

Many Q1 problems are fixable with time. Common issues include:

Our guide to common Q1 filing mistakes covers the most frequent problems and solutions.

Consider Professional Help

If you're genuinely struggling, consider hiring an accountant or bookkeeper. The cost might be less than potential penalties, and they can often resolve complex situations quickly.

Document Everything

If you're facing genuine difficulties that might constitute reasonable excuse, start documenting them now. Keep records of:

Planning for Future Quarters

Whether you make the Q1 deadline or not, use this experience to improve your approach for Q2 (due 7 November) and beyond.

Set Up Better Systems

Poor systems are the root cause of most filing difficulties. Our 75-day bookkeeping guide shows how to create robust processes that make quarterly filing routine rather than stressful.

Understand Your Deadlines

Know all your quarterly deadlines for 2026-27 and set reminders well in advance. Don't rely on last-minute rushes.

Choose Appropriate Software

If software difficulties are causing problems, review whether your current solution fits your needs. Our guides to choosing MTD software and MTD bridging software explain the options.

Get Started Free

MTD exemptions and reasonable excuses provide important safety nets, but they're not automatic get-out clauses. The key is understanding what qualifies, applying properly with strong evidence, and taking action early when problems arise. With 70 days until Q1, there's still time to address most issues and meet the deadline properly.
