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?
You need digital VAT records, MTD-compatible software, and the correct VAT registration details. 1 1 MTD Bridge connects your spreadsheet records to HMRC and validates returns before submission.
Can I upload my VAT data from a spreadsheet?
Yes. 1 1 MTD Bridge 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 validates the data and submits it to HMRC via the MTD API while keeping a digital audit trail.
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.
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.
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 four quarterly updates and one Final Declaration each year. Quarterly updates report your income and expenses, and the Final Declaration confirms your full tax position.
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, claim allowances and reliefs, and finalise your tax position. It must be submitted by 31 January following the end of the tax year.
Am I exempt from MTD for Income Tax?
You may be exempt if you are digitally excluded due to age, disability, or unreliable internet, or if HMRC gives permission. If exempt, you must still file Self Assessment in the traditional way. Contact HMRC for an exemption assessment.
