When Does MTD Start? The 6 April 2026 Deadline Explained

Making Tax Digital for Income Tax (MTD ITSA) begins on 6 April 2026 for sole traders and landlords with gross income over £50,000. If this affects you, your first quarterly update is due by 7 August 2026 - just four months away. Here's everything you need to know about the deadlines, thresholds, and what you must do right now.

The Key Dates: When MTD Actually Starts

MTD ITSA doesn't start with a bang on 6 April 2026. It begins quietly, and the real deadline pressure comes later:

The 7 August deadline is crucial. Miss this, and you'll face penalties even though you've never used MTD before.

Warning: Many people think they have until January 2028 to worry about MTD. You don't. Your first quarterly update is due just four months after MTD starts.

The £50,000 Threshold: Are You In or Out?

Whether you need MTD depends entirely on your gross income from self-employment and property rental combined.

What Counts as Gross Income

Gross income means your total business income before expenses. For MTD purposes, this includes:

It doesn't include:

If You're Over £50,000

You must use MTD from 6 April 2026. No exceptions, no delays, no opt-outs. This means:

Your gross income is measured using your 2024-25 tax year figures (6 April 2024 to 5 April 2025). HMRC will write to you if they think you need to use MTD, but don't wait for their letter.

If You're Under £50,000

You can continue filing your tax return the traditional way until April 2027. But you can also choose to start MTD early if you want to get ahead of the curve.

Starting early has advantages:

The main disadvantage is cost - you'll pay for MTD software a year earlier than required.

The £30,000 Threshold from April 2027

From 6 April 2027, the threshold drops to £30,000 gross income. This brings many more people into MTD:

If your gross income is between £30,000 and £50,000, you have one extra year to prepare. Use it wisely.

Note: The government has mentioned a possible £20,000 threshold for future years, but this isn't confirmed in law. Don't plan around unconfirmed changes.

What You Must Do Right Now

If MTD affects you from April 2026, time is running short. Here's your action plan:

Step 1: Check If You Need MTD

Calculate your gross income from the 2024-25 tax year. Add up all self-employment and property income before expenses. If it's over £50,000, you need MTD.

Use our free MTD checker if you're not sure about your situation.

Step 2: Choose Your Software

You need HMRC-approved software to submit quarterly updates. Your options include:

Most people don't need expensive full software. Bridging software handles the MTD requirements without forcing you to change how you work.

Step 3: Get Your Records Digital-Ready

Your records must be kept digitally and link to your MTD software. This doesn't mean everything needs to be automated - you can still use spreadsheets, but they must connect to your software.

Start organising your income and expense records now. Our guide to allowable expenses helps you categorise everything correctly.

Step 4: Understand the Quarterly Deadlines

MTD means quarterly reporting, not just an annual tax return. You'll submit updates by:

Each update covers a three-month period and includes your income and expenses for that quarter. See our complete deadline guide for more details.

Step 5: Test Your Setup

Don't wait until August to discover your software doesn't work or you're missing records. Set up everything now and do a practice run.

Many software providers offer free trials. Use them to make sure everything works before the first deadline hits.

What Happens If You Get It Wrong

MTD penalties are automatic and start from day one. Miss your first quarterly update by even one day, and you'll face a £200 penalty.

The penalty structure is harsh:

HMRC has said there will be some flexibility in the first year, but they haven't defined what this means. Don't rely on their understanding - get it right from the start.

Read our detailed guide to MTD penalties to understand what you're risking.

Special Considerations for Different Business Types

Sole Traders and Freelancers

If you're a sole trader, your MTD obligations are relatively straightforward. You'll report your business income and expenses quarterly, then file your final tax return as usual.

The main change is timing - you'll engage with your tax affairs four times a year instead of once.

Landlords

Property landlords face the same £50,000 threshold, but calculating gross income can be more complex with multiple properties.

You'll report rental income and allowable expenses quarterly. This includes mortgage interest, repairs, letting agent fees, and other property costs.

Our complete landlords' guide covers everything you need to know about MTD for property income.

Mixed Income (Employment + Self-Employment)

If you have a PAYE job plus self-employment or rental income, only the self-employed part goes through MTD. Your employment income continues through PAYE as normal.

But remember - the £50,000 threshold applies to your self-employed income alone, not your total earnings from all sources.

Looking Ahead: What Comes After 2026

MTD ITSA is just the beginning. HMRC's long-term plan includes:

The April 2027 threshold drop to £30,000 is already confirmed. Getting comfortable with MTD now puts you ahead of the curve for future changes.

Summary: Time to Act

MTD ITSA starts on 6 April 2026 for anyone with gross income over £50,000 from self-employment or property rental. Your first quarterly update is due by 7 August 2026 - just four months away.

The threshold drops to £30,000 from April 2027, affecting many more people. If you're caught by either threshold, start preparing now. Choose your software, organise your records, and test your setup before the first deadline arrives.

Getting MTD wrong means automatic penalties from day one. Getting it right means better financial oversight and staying ahead of HMRC's digital future.
