Do Ecommerce Sellers Need MTD? A Threshold-by-Threshold Breakdown for 2026 to 2028

Making Tax Digital for Income Tax (MTD for ITSA) has been online for the first group of taxpayers. UK e-commerce sellers want to know if they are qualified for the new MTD requirements and when they need to comply. The answer is based on the total amount of qualified income from self-employment and property. When qualified income surpasses £50,000 in April 2026, £30,000 in April 2027, and £20,000 in April 2028, HMRC intends to implement MTD for income tax in phases. This article explains which sellers qualify for each level and how MTD affects their record-keeping and revenue reporting.

What Is Making Tax Digital for Income Tax?

MTD for Income Tax, also known as MTD for ITSA, regulates the way relevant sole traders and landlords keep track of and submit their income to HMRC. It does not replace Self Assessment. MTD taxpayers are obliged to preserve digital records using compliant software, give HMRC four quarterly updates throughout the tax year, and file a declaration at the end of the year.

These updates provide information on the business’s profits and expenses. They do not constitute tax returns. The method for computing income tax liability remains the same. Simply put, there has been a change in how information is reported to HMRC. E-commerce traders use sales data from platforms such as Shopify, Amazon, Etsy, and eBay in their digital record-keeping system for MTD.

Who Actually Needs to Comply?

MTD for Income Tax applies to persons who make money from self-employment or property. Many e-commerce sellers can be subject to the same laws as sole traders. The graduated thresholds are dependent on the seller’s qualifying income as reported in the relevant Self Assessment tax return. Qualifying income for MTD purposes is the total gross income from self-employment and property before any costs. If the seller engages in more than one self-employment activity or generates income from more than one property, HMRC totals these amounts.

This is especially essential for ecommerce vendors who have several income streams. As a result, a sole trader’s qualifying revenue includes both ecommerce and rental income. MTD for Income Tax now impacts unregulated enterprises and individual landlords. A sole trader’s ecommerce revenue from a limited company does not subject him to MTD for income tax.

The Threshold Timeline: 2026 to 2028

The MTD for Income Tax for your income can be in three phases, depending on the amount of eligible income:

• Individuals earning more than £50,000 in eligible income from 2024/25 must file a Self Assessment tax return beginning April 6, 2026.
• The maximum can be reduced to more than £30,000 beginning April 6, 2027, and can be calculated using qualifying income from 2025/26.
• The maximum can be reduced to more than £20,000 beginning April 6, 2028, based on qualifying income in 2026/27.
• Under £20,000: You are not required to apply for MTD for Income Tax based on the previously mentioned levels. However, your Self Assessment responsibilities remain the same.

The first stage is presently in progress. HMRC said that around 864,000 sole traders and landlords are covered for 2026/27, with the first quarterly update due on August 7, 2026. If your 2024/25 tax return exceeds £50,000, you must have prepared for MTD beginning April 6, 2026. The barrier is based on qualifying revenue, not only e-commerce turnover.

What Changes for Your Store’s Bookkeeping?

The most important practical difference is the requirement to report quarterly. Instead of waiting until the end of the tax year to disclose your data, you need to keep digital records and submit four quarterly reports to HMRC. The quarterly deadlines for a typical tax-year accounting period are:

• 7 August
• 7 November
• 7 February
• 7 May

These reports include an overview of your revenue and expenses. However, these reports do not constitute tax returns. You must still complete your tax return and pay any taxes owed before the end of the fiscal year on January 31. Your records must be preserved digitally in MTD-compatible software and supplied electronically. This is especially true for e-commerce sellers that utilise marketplace reports, spreadsheets, and year-end accounting to assemble their sales data. While spreadsheets are not automatically thrown out, the solution you adopt must meet HMRC’s digital record-keeping and submission criteria. Many internet retailers find that using suitable accounting software can make record-keeping easier throughout the year.

Penalties for Non-Compliance

HMRC uses a points-based penalty system for late MTD submissions for income tax reasons. Under this points-based scheme, a one-point penalty is enforced for each missed quarterly submission or tax return due date after 2026/27. Once four points are accumulated, a £200 penalty is charged, with further £200 fines possible in the event of missed deadlines.

It should be noted that there is a major transition regulation for the first year of MTD for income tax. There are no penalties for late quarterly updates in 2026/27. To avoid a penalty, these modifications must be provided prior to the completion of a tax return. Late payment penalties are independent of the points system for quarterly submissions. Proportionate late payment penalties have been implemented based on the length of nonpayment. For e-commerce retailers, the first year is a grace period for late quarterly updates, but it should not be used to postpone bookkeeping and MTD software preparations.

Practical Steps for Ecommerce Sellers Right Now

Even if your qualifying income is now below £50,000, the MTD levels are scheduled to fall to £30,000 in 2027 and £20,000 in 2028. Being prepared helps you to make a smooth transition to the new bookkeeping and reporting procedure. Sellers who find themselves at the MTD threshold of any type should:

• Check your total qualifying income: Add up all of your income sources to see if and when you are going to be forced to utilise MTD for income tax.
• Keep proper digital records: You cannot rely on marketplace sales reports. Your income and spending must be digitally kept and regularly updated.
• Choose MTD-compatible software: Select software that fulfils all of HMRC’s MTD standards. Spreadsheets and bridges can be used, but a proper accounting system is a superior option.
• Separate business and personal finances: Using a separate business account can help you manage transactions and preserve better records as your ecommerce business grows.
• Review your bookkeeping setup early: If you sell on many marketplaces, have stock, or other revenue sources, seeking expert assistance ahead of time allows you to report quarterly without issue.
