Making Tax Digital, explained

A practical, plain-English guide to MTD for UK businesses, sole traders and landlords. Updated for 2026.

What is Making Tax Digital?

Making Tax Digital (MTD) is HMRC's long-running programme to move UK tax record-keeping and submission online. The idea is straightforward: keep your records digitally, send them to HMRC through software, reduce errors, close the tax gap.

In practice it means three things for most businesses: digital records, digital links, and digital submission. You can't store transactions on paper alone. You can't retype numbers between tools. You can't submit by post.

The MTD timeline at a glance

  • April 2019 MTD for VAT begins for businesses over the £85,000 threshold.
  • April 2022 MTD for VAT extended to all VAT-registered businesses regardless of turnover.
  • April 2026 MTD for Income Tax Self Assessment (ITSA) starts for sole traders and landlords with income above £50,000.
  • April 2027 MTD for ITSA threshold drops to £30,000.
  • Future MTD for Corporation Tax — currently no firm date.

What records you need to keep

For each transaction your software must hold:

  • The date of the supply
  • The net value (VAT-exclusive amount)
  • The VAT rate
  • The VAT amount (where applicable)
  • For most businesses, the supplier or customer name

A photo of a receipt isn't a digital record on its own — the underlying data has to be captured into accounting software. This is exactly the bit AvroBooks automates: the transition from a paper or PDF document to a structured, MTD-compliant record.

Digital links: the rule that catches people out

Under MTD, data must move between systems without manual retyping. A digital link can be an API connection, an exported CSV imported into another tool, a direct write between accounting and bridging software — but it cannot be someone copying a number from a spreadsheet into a tax return form.

How AvroBooks helps with MTD

  • Captures source documents and converts them into structured digital records.
  • Records every transaction with date, net, VAT rate and amount per line.
  • Syncs to Xero via API — a digital link by HMRC's definition.
  • Maintains an audit trail so you can demonstrate continuous digital records.
  • Stores documents securely in UK/EU data centres for the required retention period.

Common questions

Can I still use Excel? Yes — alongside bridging software. But the link between your Excel sheet and the bridging tool has to be a digital link, not a manual retype.

Do I have to be VAT-registered? No. MTD for ITSA applies to all sole traders and landlords once thresholds bite, regardless of VAT status.

Will MTD penalties be expensive? Initially modest — HMRC uses a points-based system before financial penalties kick in. But repeated non-compliance escalates fast.
