What is Making Tax Digital (MTD) for VAT?
Making Tax Digital (MTD) for VAT is an HMRC initiative requiring VAT-registered businesses to keep digital VAT records and submit VAT returns using MTD-compatible software. It became mandatory for all VAT-registered businesses from April 2022, unless exempt.
How often do I need to file VAT returns?
Most VAT-registered businesses must submit quarterly VAT returns (4 times per year). Each quarterly return covers a 3-month period and must be submitted within one month and 7 days of the end of the quarter.
Who must follow the MTD for VAT rules?
All VAT-registered businesses must comply with MTD rules, regardless of turnover, unless they have an exemption approved by HMRC. New VAT-registered businesses are automatically enrolled. Those below the VAT threshold may opt in voluntarily.
What are the requirements for MTD-compatible VAT filing?
  • Keep VAT records digitally using MTD-compatible software
  • Submit VAT returns electronically via an API (not the HMRC portal)
  • Maintain digital links between all data sources to avoid manual entry
  • Preserve digital VAT records for at least six years
Can I upload my VAT data from a spreadsheet?
Yes. 11taxassist supports Excel spreadsheet upload for VAT returns. You can prepare your VAT figures in a spreadsheet and upload them directly into our platform. The software will validate the data and submit it to HMRC via the MTD API — maintaining a fully digital link.
How do I sign up for Making Tax Digital for VAT?
HMRC automatically signs up VAT-registered businesses for MTD unless exempt. To file VAT returns under MTD, you'll need a Government Gateway account and VAT registration number. Agents must use an Agent Services Account (ASA) to manage clients' VAT returns.
What is MTD for Self Assessment (MTD for ITSA)?
MTD for Income Tax Self Assessment is a new HMRC initiative requiring sole traders and landlords to keep digital records and submit quarterly updates of their income and expenses using MTD-compatible software, followed by a Final Declaration at year-end. It replaces the traditional annual Self Assessment return for those who qualify.
Who needs to use MTD for Self Assessment?
You'll need to use MTD for Income Tax if you are a sole trader or landlord registered for Self Assessment and your qualifying gross income from self-employment and/or property exceeds the threshold: over £50,000 from April 2026, over £30,000 from April 2027, and over £20,000 from April 2028. Partnerships will be included at a later date.
What counts as "qualifying income" for MTD?
Qualifying income is your combined gross income (turnover before expenses) from self-employment and property. This includes UK and overseas rental income. It does not include employment income, dividends, savings interest, or pension income.
How many submissions are required each year?
Under MTD for ITSA you must submit:
  • 4 Quarterly Updates (summaries of income and expenses)
  • 1 Final Declaration (replaces your annual Self Assessment return)
Total: 5 submissions per year.
What is a Final Declaration?
The Final Declaration replaces the traditional Self Assessment tax return for MTD users. After all four quarterly updates, you confirm all income sources are complete and accurate, add any additional income (employment, dividends, etc.), claim allowances and reliefs, and finalise your tax position. It must be submitted by 31 January following the end of the tax year.
What are the quarterly update deadlines?
Q1 (6 Apr – 5 Jul): due 7 August
Q2 (6 Jul – 5 Oct): due 7 November
Q3 (6 Oct – 5 Jan): due 7 February
Q4 (6 Jan – 5 Apr): due 7 May
Final Declaration: due 31 January (following year)
What are the penalties for missing MTD deadlines?
For 2026–27, HMRC will not apply late submission penalties for missing quarterly update deadlines (soft-landing period). However, penalties for late Final Declarations and late payments still apply from day one. From 2027–28, a points-based system applies: each missed deadline earns a penalty point, and after 4 points, a £200 fine per further missed deadline.
Am I exempt from MTD for Income Tax?
You may be exempt if you are digitally excluded (e.g. due to age, disability, or location without reliable internet). If exempt, you must still file Self Assessment in the traditional way. Check your eligibility using HMRC's online tool or contact HMRC directly.
What do I need to get started?
You'll need: a Government Gateway user ID and password, your National Insurance number, your Unique Taxpayer Reference (UTR), and details of your income sources. Register on 11taxassist, connect your HMRC account, and our software guides you through everything.
Do partnerships need to use MTD for Income Tax?
Not yet. HMRC has confirmed partnerships will be brought into MTD for Income Tax at a later date, but no timeline has been set. Currently only sole traders and landlords are required to comply.
