MTD ITSA Deadline: Key Dates Every Sole Trader Needs to Know

The MTD ITSA deadline is one of the most significant changes to UK tax administration in a generation, and if you're a sole trader or landlord, it affects you directly. Making Tax Digital for Income Tax Self Assessment (MTD ITSA) will fundamentally change how you record your income and expenses and report them to HMRC. Missing the deadline or failing to prepare in time could result in penalties, compliance headaches, and a last-minute scramble to find compatible software. This guide covers everything you need to know: the exact deadlines, who is affected, what the new obligations involve, and how to get ready without the stress.

Key takeaways
  • MTD ITSA begins on 6 April 2026 for sole traders and landlords with qualifying income above £50,000.
  • From April 2027, the threshold drops to £30,000, bringing significantly more self-employed people into scope.
  • You will be required to submit quarterly digital updates to HMRC, plus a final end-of-period statement each year.
  • HMRC-compatible software is mandatory; spreadsheets alone will not be sufficient without bridging software.
  • Signing up early for the MTD ITSA pilot gives you time to understand the system before it becomes compulsory.

What Is MTD ITSA?

MTD ITSA
Making Tax Digital for Income Tax Self Assessment (MTD ITSA) is HMRC's programme that requires sole traders and landlords to keep digital records and submit quarterly updates of their income and expenses using HMRC-compatible software, replacing the traditional annual Self Assessment tax return.

MTD ITSA is the income tax arm of HMRC's wider Making Tax Digital initiative, which has already been rolled out for VAT. Unlike the annual Self Assessment system most sole traders are familiar with, MTD ITSA introduces a rolling, quarterly reporting model. You will need to:

  • Keep digital records of all business income and expenses throughout the year
  • Submit four quarterly updates to HMRC each tax year
  • Submit a final end-of-period statement (EOPS) confirming your annual figures
  • Complete a tax return finalisation (previously called a final declaration) to settle your tax liability

This is a significant shift from filling in one tax return per year. If you want a broader overview of the scheme, our complete guide to the HMRC MTD deadline for sole traders is a good place to start.

The MTD ITSA Deadline: When Does It Start?

Quarterly updates required under MTD ITSA

April 2026: The First Wave

The MTD ITSA deadline for the first group of taxpayers is 6 April 2026. From this date, sole traders and landlords with total qualifying income exceeding £50,000 per year must comply with the new rules. Qualifying income includes income from self-employment and property, added together if you have both sources.

This means that if you earned more than £50,000 from your sole trader business, your rental properties, or a combination of both in the relevant prior tax year, you will need to be fully set up and submitting quarterly updates from the start of the 2026/27 tax year.

April 2027: The Second Wave

From 6 April 2027, the income threshold drops to £30,000. Anyone with qualifying income above this level will be required to join MTD ITSA. This is expected to bring a much larger proportion of self-employed individuals into scope. If your income sits between £30,000 and £50,000, you have until April 2027, but that is not a reason to delay your preparation.

What About the £20,000 Threshold?

HMRC has confirmed plans to eventually lower the threshold to £20,000, which would capture the vast majority of sole traders. However, a specific start date for this third phase has not yet been confirmed. The government has indicated it will set that date in due course, giving affected taxpayers appropriate notice.

For a full breakdown of the phased rollout, see our post on MTD for income tax start dates and key deadlines explained.

Quarterly Submission Deadlines Under MTD ITSA

Once you are within scope of MTD ITSA, you will need to submit four quarterly updates each tax year. The quarters align with the tax year (6 April to 5 April), and HMRC has specified the following submission deadlines:

QuarterPeriod CoveredSubmission Deadline
Q16 April to 5 July5 August
Q26 July to 5 October5 November
Q36 October to 5 January5 February
Q46 January to 5 April5 May

Alternatively, HMRC is allowing some taxpayers to use calendar quarter dates (1 April to 31 March, split into calendar months), which may align better with existing accounting practices. Your MTD-compatible software should allow you to select the approach that suits your business.

Importantly, these quarterly updates are summaries of your income and expenses; they are not tax payment deadlines. Your actual tax liability is calculated and settled through the final declaration process, with payment dates following the existing Self Assessment schedule.

For a deeper look at the quarterly reporting process, our complete guide to MTD quarterly reporting deadlines covers everything in detail.

Who Is Affected by the MTD ITSA Deadline?

Sole Traders

If you run a self-employed business as a sole trader and your annual turnover or income exceeds the relevant threshold, you will be required to comply. This includes freelancers, contractors, tradespeople, consultants, and anyone else who files a Self Assessment return for self-employment income.

Landlords

Landlords with rental income above the threshold are also brought into scope. If you have both a sole trader business and rental income, the two figures are combined to determine whether you exceed the threshold.

Who Is Exempt?

Certain groups are currently exempt from MTD ITSA, including:

  • Taxpayers in a partnership (though MTD for partnerships is planned for a later date)
  • Those with income below the relevant threshold
  • Individuals whose tax affairs are managed by a trustee, personal representative, or insolvency practitioner in some circumstances
  • Those who can demonstrate that digital record-keeping is not reasonably practicable due to age, disability, or religious beliefs (subject to HMRC approval)

If you are unsure whether you fall within scope, HMRC's online tools and a conversation with your accountant or a compliant software provider can help you confirm your position.

What You Need to Do Before the Deadline

Step 1: Check Whether You Are in Scope

Look at your income from self-employment and property for the most recent complete tax year. If the combined total exceeds £50,000, you need to be ready by 6 April 2026. If it exceeds £30,000 but not £50,000, your deadline is 6 April 2027.

Step 2: Choose Compatible Software

HMRC will not accept quarterly updates submitted manually or via standard spreadsheets without bridging software. You must use software that is recognised by HMRC for MTD ITSA. Look for tools that offer:

  • Digital record-keeping for income and expenses
  • Direct submission of quarterly updates to HMRC
  • End-of-period statement and final declaration functionality
  • Clear categorisation of expenses in line with HMRC requirements

TapTax is designed specifically for sole traders navigating MTD ITSA, making it straightforward to log income, categorise expenses, and submit quarterly updates without needing an accounting background.

Step 3: Start Keeping Digital Records Now

Even if your deadline is April 2026 or 2027, the sooner you switch to digital record-keeping, the easier the transition will be. Habits formed now will make quarterly reporting feel routine rather than burdensome when it becomes mandatory. This includes keeping receipts digitally, logging income as it arrives, and categorising every transaction.

Step 4: Consider Joining the Pilot

HMRC runs a voluntary MTD ITSA pilot programme that allows eligible taxpayers to sign up early and experience the system before it becomes compulsory. Joining the pilot gives you time to iron out any issues, get familiar with your software, and ensure your records are structured correctly. Eligibility for the pilot has expanded over time, so it is worth checking whether you qualify.

Step 5: Speak to Your Accountant

If you use an accountant or bookkeeper, bring them into your planning now. They will need to understand the new quarterly workflow and may already be recommending MTD-compatible software to their clients. Early conversations prevent last-minute surprises.

Penalties for Missing the MTD ITSA Deadline

HMRC is introducing a new points-based penalty system for MTD ITSA. Rather than an immediate financial penalty for a single missed submission, you accrue penalty points each time you fail to submit on time. Once you reach a points threshold, a financial penalty of £200 is applied, with further penalties for continued non-compliance.

This system is designed to be fairer to those who have occasional slip-ups while ensuring persistent non-compliance is penalised. However, the best approach is straightforward: submit on time, every time, using compliant software.

Late payment of tax will continue to attract interest and surcharges under the existing rules, so keeping up with your quarterly records will also help you budget accurately for your tax bill throughout the year rather than facing a surprise in January.
