Making Tax Digital for VAT
Invoicemonk keeps your UK VAT records in the HMRC-required digital form, with every box-1-to-box-9 figure traceable back to the source invoice, and submits the VAT return through the HMRC MTD API. Live since April 2022.
Built for United Kingdom from day one
What MTD for VAT requires
HMRC MTD for VAT (in force for all VAT-registered businesses since 1 April 2022) requires digital record keeping for VAT data, a digital link between source invoices and the return, and submission of the VAT return through HMRC's MTD API rather than the legacy portal. Manual cut-and-paste or unlinked spreadsheets are non-compliant.
How Invoicemonk meets MTD
Every invoice line carries the VAT rate, net, VAT amount, and reverse-charge flag; box 1–9 figures are computed from the invoice ledger with full digital linkage. The VAT return is filed through the HMRC MTD API via OAuth2; obligations, returns, and payments flow back into the dashboard. Reverse charge for construction services (CIS) and EU acquisitions/dispatches post-Brexit are handled correctly.
Who this applies to
All UK VAT-registered businesses, regardless of turnover. Voluntary registrations are included since April 2022.
Cryptographic artefacts, in every jurisdiction we cover
Invoicemonk issues cryptographically signed structured invoices in every one of the 18 jurisdictions we cover, using the local artefact the tax authority requires:
- CSID — ZATCA (Saudi Arabia)
- IRN — GST India (NIC IRP), FIRS Nigeria, GRA Ghana
- UUID — MyInvois Malaysia
- QR + Control Unit Number — KRA eTIMS (Kenya)

Each mandate page documents the local artefact, signing algorithm, certificate authority, and the spec section that requires it.
