For Sole Traders and Landlords Affected by Making Tax Digital (MTD)

Many business owners still see Making Tax Digital as “just another HMRC admin burden.”

That mindset could become an expensive mistake.

Since April 2026, many sole traders and landlords with qualifying income over £50,000 have been required to keep digital records and submit quarterly updates to HMRC through compatible software. HMRC has made it clear that MTD is a major part of its strategy to reduce errors, improve compliance and close the tax gap.

If you’re thinking of ignoring quarterly submissions or delaying compliance, here’s what you need to know.

HMRC Is Watching More Closely Than Ever

Making Tax Digital wasn’t introduced simply to modernise bookkeeping.

One of HMRC’s key objectives is to reduce the billions of pounds lost through errors, omissions and late reporting each year. The move to digital reporting gives HMRC greater visibility of business and property income throughout the year rather than waiting for a single annual tax return.

With increased use of data analytics, artificial intelligence and thousands of additional compliance officers, HMRC’s ability to identify non-compliance is significantly stronger than it was a few years ago.

Missing One Deadline May Not Hurt

But Repeatedly Missing Them Will

Under MTD’s penalty points system, missing a filing deadline does not automatically lead to a financial penalty.

Instead, HMRC issues a penalty point.

For taxpayers required to file quarterly, points accumulate until a threshold is reached. Once that threshold is hit, HMRC can issue a £200 penalty, with further penalties applying for continued failures.

Many business owners wrongly assume:

“It’s only a point.”

The reality is that every missed deadline creates a compliance history.

What Does a Build-Up of Penalty Points Tell HMRC?

Penalty points create a digital trail.

Repeated late submissions can indicate:

• Poor record keeping.
• Weak financial controls.
• A lack of engagement with tax obligations.
• A higher risk of future compliance failures.

While HMRC does not automatically open a compliance check solely because of penalty points, a pattern of missed obligations can increase your risk profile and make your affairs more likely to attract attention. HMRC’s compliance activity is increasingly data-driven and focuses on identifying taxpayers that appear to present a greater compliance risk.

In simple terms:

Businesses that regularly fail to meet their obligations are more likely to appear on HMRC’s radar.

The Financial Cost of Non-Compliance

Many sole traders only think about penalties.

The real cost can be much higher.

Direct Costs

You could face:

• £200 fixed penalties.
• Additional penalties for continued failures.
• Interest charges on unpaid tax.
• Potential professional fees if HMRC opens an enquiry.

Indirect Costs

The indirect costs are often far greater:

• Lost working time.
• Stress and disruption.
• Additional bookkeeping costs.
• Delayed tax planning opportunities.
• Reduced confidence in your financial records.

What Happens If HMRC Opens a Compliance Check?

A compliance check can involve HMRC requesting:

• Bank statements.
• Invoices.
• Expense records.
• Property income records.
• Mileage evidence.
• Supporting documentation for claims.

HMRC’s Connect system cross-checks information from many sources including banks, property records and other third-party data. Discrepancies can quickly raise questions.

The longer poor record keeping continues, the harder and more expensive it becomes to correct.

Lenders Are Becoming More Interested in Tax Compliance

This is the hidden consequence most people never consider.

When applying for:

• A mortgage
• A buy-to-let mortgage
• Business finance
• Asset finance
• Commercial lending

lenders frequently request:

• Tax returns
• SA302s
• Tax year overviews
• Accounts
• Evidence of income

If your records are incomplete, returns are late, or your tax affairs are under review, it can affect the lender’s confidence in your application.

Lenders want evidence that:

• Income is reliable.
• Records are accurate.
• The business is well managed.
• Future tax liabilities are under control.

Repeated compliance issues may not just cause HMRC problems; they can create borrowing problems too.

Landlords Face Additional Risks

Landlords entering MTD are facing greater scrutiny than ever before.

HMRC is increasingly using property data, Land Registry information and other third-party sources to identify undeclared or incorrectly reported rental income. Recent compliance campaigns have already targeted landlords through so-called “nudge letters” and disclosure campaigns.

For landlords, staying compliant with quarterly reporting is becoming a key part of demonstrating that rental businesses are properly managed.

---

The Excuse “I Didn’t Know” Is Becoming Harder to Use

MTD has been discussed for years.

HMRC has issued extensive guidance and communications on the new requirements. The expectation is increasingly that taxpayers understand and meet their obligations.

As digital reporting becomes the norm, businesses that fail to adapt may find themselves struggling to justify repeated failures.

Bkeepers Warning

The biggest risk isn’t the first missed submission.

The biggest risk is developing a pattern of non-compliance.

One missed update may result in a point.

Several missed updates can lead to penalties.

A history of missed obligations can increase HMRC scrutiny.

Poor compliance can damage lender confidence and make it harder to secure finance when you need it most.

The businesses that thrive under Making Tax Digital will be the ones that keep records up to date, submit on time and treat compliance as part of running a professional business.

Don’t wait until penalty points start stacking up. Getting organised today is significantly cheaper than dealing with HMRC tomorrow.
