New Tax Rules for UK Sole Traders — Quarterly Submissions and Threshold Changes Explained

new tax rules are on the way — and they’re going to change how you report your income.

You may have heard about quarterly tax submissions or Making Tax Digital (MTD), but a lot of people still aren’t clear on what it actually means in practice.

This guide breaks it down in plain English — so you know exactly what’s changing, who it affects, and what you need to do next.

What Are the New Tax Rules for Sole Traders?

The biggest change is how often you report your income to HMRC.

Under the new Making Tax Digital (MTD for Income Tax) rules, sole traders will need to:

👉 Submit updates to HMRC every 3 months (quarterly)👉 Keep digital records of income and expenses👉 Submit a final end-of-year declaration

Instead of one yearly Self Assessment, you’ll now be reporting your business activity throughout the year.

What Are Quarterly Tax Submissions?

Quarterly submissions are regular updates sent to HMRC every three months.

These updates include:

• Income (what you’ve earned)

• Expenses (what you’ve spent)

• Estimated profit

They’re not full tax returns — more like progress updates.

At the end of the tax year, you’ll still confirm everything with a final submission.

When Do the New Rules Start?

The rollout is happening in stages:

• April 2026 → Sole traders earning over £50,000

• April 2027 → Sole traders earning over £30,000

If you’re below that threshold, you won’t be affected straight away — but it’s expected to expand further in the future.

What Is the Threshold for Making Tax Digital?

The key thresholds are based on annual turnover (not profit):

• Over £50,000 → MTD starts in 2026

• Over £30,000 → MTD starts in 2027

👉 Important: This is based on your total income before expenses

So even if your profit is lower, you could still fall into the new system.

Do Sole Traders Have to Pay Tax Quarterly?

No — not at the moment.

This is one of the biggest misconceptions.

👉 You will report quarterly👉 But you will still pay tax through the existing system (for now)

However, many expect payment changes to come in the future — so getting used to regular reporting now is important.

Do You Need Accounting Software?

Yes — this is a key part of the change.

HMRC requires you to use MTD-compatible software to:

• Record income and expenses

• Submit quarterly updates

Popular options include simple mobile apps designed for trades and sole traders.

The upside is you’ll:

• Stay organised throughout the year

• Avoid last-minute stress

• See your finances clearly

How Will This Affect Sole Traders Day-to-Day?

This is where the real impact is.

If you currently:

• Keep rough notes

• Catch up once a year

• Rely on your accountant at the last minute

That approach will need to change.

Instead, you’ll need to:

• Keep records up to date

• Track income and expenses regularly

• Stay on top of your numbers throughout the year

It’s less about doing more work — and more about spreading it out.

Benefits of the New Tax System

While it might feel like extra admin, there are real benefits:

• No more last-minute tax panic

• Better visibility of your income

• Fewer surprises when your tax bill arrives

• More control over your finances

For many sole traders, this could actually improve how they manage money.

What Happens If You Don’t Comply?

HMRC is introducing a points-based penalty system.

Missed submissions = pointsToo many points = fines

So staying organised isn’t optional — it’s essential.

What Should Sole Traders Do Now?

The best move is to prepare early.

Start by:

• Keeping digital records now (even basic ones)

• Tracking income monthly

• Getting familiar with simple accounting apps

• Speaking to your accountant if you have one

The sooner you adapt, the easier the transition will be.

The Future of Tax for Sole Traders

This is part of a wider shift.

HMRC is moving towards:

• Real-time reporting

• Fully digital systems

• More frequent updates

Quarterly submissions are just the beginning.
