Important: K3 recommends reading all of the Digital VAT (UK) documentation here before starting training or testing on the K3 Digital VAT (UK) App. Failure to do so may lead to making an incorrect submission and the potential for locking data accidentally.


Before you can use the K3|imagine Making Tax Digital (MTD) app, you need to sign up with HMRC for the Making Tax Digital scheme.


You can find more information about signing up to the scheme in the HMRC's Overview of Making Tax Digital.


HMRC gives you a Government Gateway login that you use to identify yourself and the App to the HMRC Making Tax Digital Service. You need this login when you first use the Making Tax Digital (MTD) app.


The following prerequisites also apply:


  • You have installed connector/bridging software between your financial system(s) for VAT and the K3|imagine Digital VAT (UK) app.
  • VAT setups are configured fully in your financial system(s).
  • You have configured your financial system to extract VAT records and send them to the K3|imagine Digital VAT (UK) app.
  • You have uploaded transactions for the period you wish to submit, via your connector/bridging software, to the K3|imagine Digital VAT (UK) app.
