Making Tax Digital (MTD) is a pivotal move by HMRC to modernise the UK tax system. Through the use of digital tools, it aims to simplify the tax process, reduce errors, and ensure more accurate tax returns. However, while MTD brings efficiency, it also introduces a risk of penalties. This guide explains everything UK businesses need to know about avoiding penalties under Making Tax Digital, ensuring full compliance and peace of mind.

Understanding Making Tax Digital (MTD)
Making Tax Digital is a government initiative aimed at transforming tax administration by making it more effective, efficient, and easier for taxpayers. MTD requires businesses and individuals to maintain digital records and submit updates to HMRC using functional compatible software.
Online sellers using digital platforms must stay compliant, and our Ecommerce Accountants UK team can help ensure you meet all MTD obligations.
This digital service began with VAT-registered businesses, but it's gradually expanding to cover income tax for self-employed individuals and property income recipients under MTD for ITSA (Income Tax Self Assessment).
Key elements of MTD include:
-
Maintain electronic records
-
Submit quarterly updates to HMRC
-
Use MTD-compatible software
-
Avoid manual data entry
Who Needs to Comply With MTD?
VAT Registered Businesses
All VAT-registered businesses must now follow MTD rules for VAT, regardless of turnover. The VAT registration threshold is currently £90,000 (increased from £85,000 in April 2024). You must keep VAT records digitally and file VAT returns via MTD-compatible software.
Self-Employed & Sole Traders
-
April 2026: Self-employed individuals with business or property income over £50,000 will need to comply with MTD for ITSA
-
April 2027: Those earning above £30,000 will follow
-
April 2028: Those earning above £20,000 will need to comply
Property Income Earners
Landlords with qualifying income from rental properties will also fall under MTD rules. This includes those with joint property income and married couples allowance recipients.
Important Note on Partnerships
Partnerships are currently excluded from MTD for ITSA regulations. HMRC intends to extend MTD to partnerships in the future, but no date has been announced.

Required Software for MTD
Functional Compatible Software

-
Record and store electronic records
-
Submit data to HMRC via digital links
-
Maintain adequate records
MTD Compatible Software Options
Popular options include:
All offer features such as automatic VAT calculations, bank statement imports, and support for quarterly submissions. Cloud-based MTD software is recommended for easy access and data security.
Keeping Electronic Records Accurately
Digital records must include:
-
Business name, address, and National Insurance number
-
VAT number (if applicable)
-
Details of income and expenses
-
Accounting period dates
-
Invoices, bank statements, and receipts
Important: Quarterly updates are now cumulative, allowing errors to be corrected as part of the following update without needing to resubmit previous quarters.
Quarterly Submissions Explained
Instead of the traditional annual tax return, businesses under MTD must submit digital quarterly updates. This ensures HMRC receives real-time data and helps you stay on top of your tax affairs.
Submission Deadlines
The quarterly deadlines are the 7th of the month after the quarter end (changed from the 5th to align with VAT reporting deadlines):
-
Jan-Mar: 7 May
-
Apr-Jun: 7 August
-
Jul-Sep: 7 November
-
Oct-Dec: 7 February
Late or missed submissions attract penalty points and potential financial penalties.
Common Pitfalls and Errors
-
Not using compatible software
-
Missing a VAT return deadline
-
Incomplete or inaccurate business records
-
Forgetting to submit quarterly updates
-
Using multiple platforms without digital links
Penalties for Non-Compliance
Late Submission Penalty Points
You get one penalty point per missed deadline. When you hit the threshold (e.g., four points for quarterly submissions), a £200 penalty applies. Points accrue separately for VAT and Income Tax.
Points thresholds:
-
Monthly submissions: 5 points = £200 penalty
-
Quarterly submissions: 4 points = £200 penalty
-
Annual submissions: 2 points = £200 penalty
Points expire after 24 months if you remain below the threshold.
Late Payment Penalties (Updated Rates from April 2025)
No penalty for the first 15 days
After 15 days: 3% penalty on the outstanding tax amount
After 30 days: Additional 3% penalty on the outstanding tax amount (total 6%)
After 31+ days: 10% per annum daily interest on the outstanding amount
Interest Rate: HMRC charges interest at 8.5% from April 2025 (Bank of England base rate plus 4 percentage points).
Inaccuracy Penalties
Incorrect submissions due to negligence or deliberate errors incur penalties ranging from 15% to 100% of the tax due.
