Missing MTD Deadlines: An Expensive Oversight
Making Tax Digital (MTD) is a key part of the UK government’s plan to streamline the tax system. But failing to meet your MTD obligations on time can have costly consequences — from HMRC penalties to unwanted stress. In this second edition of our ‘Mistake Spotlight’ series, we explain how to steer clear of these pitfalls and keep your business compliant and penalty-free.
What is MTD and Why Does It Matter?
Introduced by HMRC, MTD requires UK businesses to maintain digital records and submit tax returns using compatible software. Initially rolled out for VAT-registered businesses, MTD is gradually expanding to cover Income Tax (MTD for ITSA) and Corporation Tax in the coming years.
MTD aims to reduce errors and improve efficiency, but these benefits rely on businesses keeping up with the deadlines. Ignoring MTD submission dates means you could face late filing penalties or interest on unpaid tax.
Key MTD Deadlines You Can’t Afford to Miss
- VAT-registered businesses: Quarterly VAT returns must be filed digitally using MTD-compliant software. These are due one month and seven days after the end of each VAT period.
- Self-employed and landlords (from April 2026): Individuals with income over £50,000 must submit quarterly income tax updates under MTD for ITSA.
- Annual final declaration: A final end-of-year declaration must also be submitted under MTD for ITSA by 31 January after the end of the tax year.
Missing these deadlines can result in automatic penalties. Under HMRC’s new points-based penalty system, repeated delays will quickly stack up, costing you hundreds of pounds without warning.
Common Mistakes and How to Avoid Them
Too many businesses get caught out by simple oversights. Here are some common MTD compliance errors:
- Relying on manual processes: Using spreadsheets or outdated software that’s not MTD-compliant can lead to filing delays or rejections.
- Forgetting submission dates: Without proper reminders or systems in place, it’s easy to miss deadlines — especially if you manage multiple tax obligations.
- Assuming your accountant does it all: While many accountants handle MTD filings, not all are proactive. It’s important to stay engaged with your responsibilities.
To sidestep these problems, choose MTD-compatible software that suits your business size and sector, and develop a filing calendar or reminders to stay ahead of deadlines.
