What Making Tax Digital (MTD) Actually Is!

Making Tax Digital (MTD) is the UK government’s (HMRC’s) major programme to digitise tax reporting so that businesses and individuals keep continuous digital records and submit tax information digitally throughout the year, not just once a year.

Originally launched for VAT in April 2019, MTD is now being expanded to Income Tax Self-Assessment (ITSA) for the self-employed and landlords.

MTD for Income Tax: Rollout Timeline

MTD for Income Tax Self-Assessment (ITSA) is rolling out in phases based on your combined gross income from self-employment and/or property:

Date	Who Must Start Using MTD
6 April 2026	Sole traders & landlords with qualifying income > £50,000 must start MTD.
6 April 2027	Those with income > £30,000 must start MTD.
6 April 2028	Those with income > £20,000 must start MTD.

HMRC will confirm your deadline based on your latest Self-Assessment or you can check your position early and sign up before your deadline.

Digital filing replaces the old paper system, even account spreadsheets must be digitally linked to MTD-recognised software.

What You’ll Have To Do Under MTD

Keep Digital Records

This is the foundation of MTD: record all income and expenses digitally as they happen, no more shoeboxes or paper receipts.

Your digital records must include:

✔ Income received (sales, services, rentals)

✔ Business expenses and costs

✔ VAT details (if applicable)

✔ Purchases & receipts

✔ Bank records (digitally captured)

✔ Linked digital data, no manual transcription

You must use software that is HMRC-recognised and MTD-compatible (e.g., Xero, QuickBooks, FreeAgent, Sage).

Submit Quarterly Updates Rather Than One Annual Return

Instead of just one annual Self-Assessment tax return, you must send:

📍 Four quarterly summaries of your income and expenses to HMRC

📍One Final Declaration at year-end to confirm total tax liability

These quarterly updates are simple summaries, not fully adjusted tax returns, but must be sent digitally.

Typical reporting dates (aligned to the tax year):

📅 7 Aug (6 Apr–5 Jul)

📅 7 Nov (6 Jul–5 Oct)

📅 7 Feb (6 Oct–5 Jan)

📅 7 May (6 Jan–5 Apr)

⚠️ The final tax payment and annual declaration is still due 31 January

Why HMRC Is Making This Change

MTD is designed to:

• Reduce errors by digitising tax records

• Give taxpayers up-to-date views of their tax position

• Close the “tax gap” (unpaid or incorrectly paid taxes)

• Modernise tax reporting for the digital era

  
  

It’s the biggest transformation of tax filing since Self-Assessment was introduced.

Simple MTD Checklist (What Must Be Included in the Calculations)

Your bookkeeping and software must be able to record:

☑ Total business income (gross before expenses)

☑ All allowable expenses with receipts

☑ Rent or property income (if applicable)

☑ Bank transactions digitally imported

☑ Sales invoices and purchase invoices

☑ Mileage and petty cash (digitally captured)

☑ VAT (if you’re already VAT-registered)

☑ Adjustments for overlap relief, capital allowances, etc. (at year-end)

Remember: quarterly updates are summary figures, keep detailed records online, not offline paper

Why Bookkeeping Matters More Than Ever

MTD changes when and how you record your numbers:

• No More Year-End Panic

Under MTD, you’ll be reporting throughout the year, so waiting until January to sort out records just won’t work anymore.

• Real-Time Financial Insight

Cloud software gives visibility of profitability, tax liabilities, cash flow and expenses — often automatically categorised.

• Help Reduce Penalties

Missed quarterly updates can trigger HMRC’s points-based penalty system — points add up to fines.

• Better Planning

With continuous books, you can plan for tax liabilities rather than being surprised at year-end.

Practical Tips & Best Practices

✔ Start Small and Early

Begin logging income and expenses as they happen, even if your start date is later. The earlier you switch, the easier compliance will be.

✔ Use Cloud Software

Cloud accounting means:

• automatic bank feeds

• mobile receipt capture

• recurring invoices

• reminders for outstanding bills

  
  

Software like QuickBooks and Xero have MTD built-in and will help automate updates to HMRC.

✔ Separate Your Accounts

A dedicated business bank account simplifies record-keeping and reduces errors.

✔ Collaborate With a Professional

Industry podcasts and accounting professionals regularly highlight that MTD is not just a compliance change, but a shift in how businesses manage their finances, particularly around software setup, digital processes and forward tax planning

✔ Don’t Ignore Digital Linking Rules

Under MTD you must ensure different pieces of software hold linked data (not copy-pasted), part of compliance.

What About Penalties Under MTD?

Making Tax Digital falls under HMRC’s points-based penalty system for late submissions.

Instead of an automatic fine for each missed deadline, you receive a penalty point every time you miss a quarterly update or final declaration deadline.

How It Works

• Each late submission = 1 penalty point

• Points accumulate until you reach a threshold

• Once the threshold is reached, you receive a £200 fine

• Every additional missed deadline after that = another £200 fine

  
  

The threshold depends on how often you submit:

Submission Frequency	Penalty Threshold
Annual	2 points
Quarterly	4 points
Monthly	5 points

Since MTD for Income Tax requires quarterly updates, most sole traders and landlords will fall into the 4-point threshold category.

How Long Do Points Last?

Penalty points remain on your record until you:

1. Reach the compliance period (usually 12 months of on-time submissions), and

2. Submit all outstanding returns.

This means missed deadlines can affect you for some time if not addressed.

Late Payment Penalties

MTD also links into HMRC’s late payment penalty rules:

• 0–15 days late: No penalty (if paid within 15 days)

• 16–30 days late: 2% penalty

• 31+ days late: 2% plus daily interest

• Ongoing interest charged from the due date

Even though quarterly updates do not trigger tax payments, the final tax bill still follows the normal 31 January deadline and payment rules.

Will There Be Penalties in the First Year?

The points-based penalty system applies from the start of mandation. This means late submissions can result in penalty points, and once the threshold is reached, financial penalties apply.

While HMRC has previously taken a supportive approach during the early stages of major changes, there is no formal exemption from penalties in the first year.

Staying organised and keeping digital records throughout the year will significantly reduce the risk of issues.

Why This Matters Under MTD

With four submissions per year instead of one, there are more deadlines to manage.

Good digital bookkeeping and regular review of your figures makes it much easier to:

✔ Avoid missed submissions

✔ Avoid accumulating penalty points

✔ Understand your tax position before payment deadlines

✔ Stay compliant without last-minute stress

Final Thought: MTD Isn’t Just Compliance. It’s Better Business

MTD doesn’t just change how you report tax, it fundamentally changes when you engage with your finances.

It encourages:

✅ Better bookkeeping habits

✅ Continuous oversight of financial performance

✅ Easier tax planning and less stress

✅ Fewer surprises at year-end

Yes, it is a change, but with the right tools and habits, it can make tax smoother and your business stronger.
