Making Tax Digital - functional compatible software

Under the new UK Making Tax Digital (MTF) VAT rules, ‘Functional Compatible Software’ is a single program or set of programs, products or software applications that are able to:

  • Record and store VAT digital records;
  • Submit to HMRC data for the completion of VAT returns via HMRC’s API platform; and
  • Receive data and information in return from HMRC via the API platform.

Where software is not able to perform all of the above requirements, for example a spreadsheet, it may be used in conjunction with other packages or bridging software to complete the digital journey.

Digital Links for data transfer

A digital link is an electronic or digital transfer or exchange of data between software programs, products and applications.

Where there is a transfer of VAT data between packages in the completion of the return, this must be done digitally without manual intervention. There must be digital links between the programs, apps etc., where there is any transfer, copy and pasting, recapture or modification of the data. Each piece of software must be digitally linked to create the digital journey.

Digital links may include:

  • A digital link may include linked cells on spreadsheets
  • Emailing spreadsheet, CVC or similar data where it is then uploaded into other software for the return preparation
  • Transfers via memory sticks or similar portable device
  • XML and CSV imports or exports
  • API transfers
  • But excludes ‘cut and paste’ manual process to move data

HMRC will provide for a 1-year digital link soft-landing. This means until 30 March 2020, businesses will not be required to have all digital links in place. The exception is the transfer of data to the API filing. This must be done digitally.


VAT return filings

The submission of the VAT return data, and any other supplementary data, must be via an Application Programming Interface (AFI). This should be via API-enabled accounting software, but the following alternatives are acceptable:

  • Bridging software which connects accounting software to the HMRC API Platform, and allow data to be sent back and forth
  • API-enabled spreadsheets that incorporate the MTD APIs. They may record the VAT transactions themselves, or combine with accounting software to submit the VAT return data
