MTD 2026 Changes: Will You Be Ready?

From April 2026, Making Tax Digital (MTD) will change how millions of sole traders, landlords, and small businesses file their taxes. MTD 2026 Changes bring with it quarterly reporting which will replace the once-a-year return, and HMRC will expect every number to be submitted through approved digital software.

Miss a deadline and penalties will follow. Start preparing early, and the switch can be smooth. This guide breaks down the MTD 2026 changes in plain English—what’s changing, when it kicks in, and how to avoid HMRC penalties.

What is Making Tax Digital?

Making Tax Digital is HMRC’s plan to end paper returns and move everyone into a fully digital system. Instead of submitting one annual tax return, you’ll send quarterly updates, keep records digitally, and file a final declaration at year-end.

The aim is simple: cut down on errors, speed up reporting, and give HMRC a real-time view of your income. But for you, it means new habits, new software, and making sure every figure is right before it goes in.

For background, see HMRC’s official guidance on modernising the tax system through Making Tax Digital.

The MTD 2026 Changes Explained

The big date is 6 April 2026. From then, MTD for Income Tax Self Assessment (ITSA) applies to landlords and sole traders with income over £50,000.

One year later, from 6 April 2027, the threshold drops to £30,000. And the government has already announced plans to extend it further in April 2028 to those earning more than £20,000.

Note: the 2028 change is still subject to final legislation.

Under the new rules, you’ll need to:

• Keep digital records of all business and property income.
• Submit quarterly updates using HMRC-approved software.
• File an End of Period Statement and a Final Declaration at year-end.

This is a big shift from the once-a-year Self Assessment. For many, it means moving to new software, adjusting workflows, and keeping much tighter records.

Three years ago we advised clients to get ready for MTD. With the Making Tax Digital 2026 changes now close, those preparations are no longer optional.

Deadlines You Can’t Afford to Miss

HMRC isn’t giving much wiggle room on the rollout. Miss a date, and you’ll pay for it.

• 6 April 2026: MTD for ITSA starts for landlords and sole traders with income above £50,000.
• 6 April 2027: Threshold lowers to £30,000.
• 6 April 2028: Planned extension to £20,000 (pending legislation).

Once in the system, you’ll need to file:

• Quarterly updates every three months.
• An End of Period Statement (EOPS).
• A Final Declaration that replaces the annual tax return.

The first quarterly submission deadline falls on 07/08/2026, which relates to the quarter 06/04/2026 to 05/07/2026. Put it off until July, and you’ll be racing the clock.

HMRC Digital Reporting: What It Means in Practice

Under MTD, you can’t keep paper ledgers or type figures straight into HMRC’s Self Assessment system. Everything must be recorded and submitted digitally.

That means:

• Using MTD-compatible software to log income and expenses.
• Updating records regularly, not once a year.
• Sending quarterly figures direct to HMRC.

For many small businesses and landlords this is a culture shift, as last-minute catch-ups will no longer cut it. HMRC wants real-time, accurate data, which can be in the form of spreadsheets, incorporated with the use of a bridging software to make the submissions.

Ask yourself: if HMRC asked for your figures today, could you send them digitally and on time? If not, now’s the time to prepare. Our tax compliance and planning services help businesses set up the right systems before the rules kick in.

Penalties Under the New System

MTD brings in a points-based penalty system. Each late submission earns a point. Four points, and you get an automatic £200 fine. Every missed deadline after that adds another £200.

Stick to the rules and make submissions accurately and on time. Under the points-based late submission regime, the penalty points reset requires a period of compliance of 12 months for quarterly obligations and that all submissions due in the preceding 24 months have been made.

For example, a sole trader missing four quarterly updates in a year could face £800 in fines, plus interest on overdue tax. That’s before you even deal with the admin hassle of HMRC letters.

The message is simple: stay on top of deadlines, or pay the price.

Preparing for Income Tax Digital Filing

Avoiding fines isn’t complicated—it comes down to planning and using the right systems.

Here’s how to get ready:

• Choose and set up MTD-compatible software well before April 2026.
• Keep business and personal finances separate.
• Update records regularly instead of waiting until quarter-end.
• Train staff—or yourself—on how to file quarterly updates.

Think of it as moving from one annual deadline to four smaller ones. The workload isn’t bigger, but it does demand discipline.

Our accounting services support small businesses and sole traders through the change, making sure their systems are both efficient and compliant.
