Making Tax Digital (MTD) Compliance Guide - United Kingdom

Making Tax Digital (MTD) is HMRC's initiative to modernise the UK tax system. Since April 2022, all VAT-registered businesses must keep digital records and submit VAT returns through MTD-compatible software. This means no more manual spreadsheets or paper records for VAT purposes. Your accounting software must be MTD-compliant, and your digital records must include specific information about each transaction.

Step-by-Step Process

  1. 1

    Ensure your accounting software is MTD-compatible (Xero is fully compliant)

  2. 2

    Set up digital record keeping for all transactions

  3. 3

    Record the time of supply, value of supply and rate of VAT for each transaction

  4. 4

    Maintain digital links between your records and VAT return submission

  5. 5

    Do not manually transfer data between systems - use digital links only

  6. 6

    Submit your VAT return directly through MTD-compatible software to HMRC

  7. 7

    Keep digital records for at least 6 years

Frequently Asked Questions

Is Xero MTD-compliant?

Yes. Xero is fully MTD-compliant for VAT. SortBooks doesn't submit VAT returns. You still file through Xero's MTD submission, and SortBooks helps by keeping the VAT codes right on the transactions you approve.

What are the penalties for not complying with MTD?

HMRC uses a points-based penalty system. You receive a point for each late submission. Once you reach the threshold (4 points for quarterly filers), you receive a financial penalty of GBP 200 for each subsequent late submission.

How does SortBooks ensure MTD compliance?

SortBooks maintains fully digital records in Xero with proper digital links. Every transaction is categorised with correct VAT codes, and VAT returns can be submitted directly to HMRC through Xero - no manual intervention needed.
