Making Tax Digital (MTD) Deadlines: What UK Businesses Must Know for 2026 & Beyond
Making Tax Digital (MTD) is transforming how UK businesses, landlords, and self-employed individuals manage their tax affairs. Introduced by HM Revenue & Customs (HMRC), MTD moves the UK tax system fully online—reducing errors, improving efficiency, and simplifying compliance.
If you’re wondering about MTD deadlines, who they apply to, and how to prepare, this guide from 11TaxAssist explains everything in plain English.
What Is Making Tax Digital (MTD)?
Making Tax Digital is HMRC’s initiative to digitalise the UK tax system. Under MTD, businesses and individuals must:
- Keep digital tax records
- Use HMRC-compatible accounting software
- Submit tax updates electronically
This replaces paper records and older manual submission methods.
Is Making Tax Digital Only for VAT?
No. Making Tax Digital applies to more than just VAT.
Current & Upcoming MTD Rollout
- MTD for VAT – Live since April 2022
- MTD for Income Tax (ITSA) – Starts April 2026
- MTD for Corporation Tax – Expected no earlier than April 2026
Why Is HMRC Introducing Making Tax Digital?
HMRC’s key goals include:
- Reduce costly tax errors
- Save time for businesses and the self-employed
- Cut the estimated £10 billion lost each year through mistakes
- Create a paperless, digital tax system
For business owners, this means better accuracy — but stricter compliance.
What Is the MTD Deadline?
MTD for VAT (Already Active)
If you are VAT-registered, MTD already applies to you — even if you registered voluntarily.
- Deadline: April 2022 (already passed)
- VAT records must be kept digitally
- VAT returns submitted via MTD software
MTD for Income Tax (ITSA) – Key Dates
If you’re self-employed or a landlord, these deadlines matter most:
- April 2026 – Income over £50,000
- April 2027 – Income £30,000–£50,000
You’ll need to submit quarterly digital updates, plus an annual declaration.
Missed the MTD Deadline? Will You Be Fined?
Yes — but here’s how penalties work under HMRC’s new system:
- Miss a deadline → penalty point
- Reach the threshold → £200 fine
- Late payments → penalties up to 4%
This system works similarly to driving penalty points.
How to Register for MTD (Important Timing Rules)
- Register at least 3 days before VAT deadline (no Direct Debit)
- Register at least 7 days before VAT deadline (with Direct Debit)
Late registration can delay payments and trigger penalties.
