This quick start guide documents how to work with Making Tax Digital for VAT within CCH OneClick.

Note: you need to have signed up/subscribed to MTD for VAT on HMRC’s website, otherwise you will not be able to authorise CCH OneClick with HMRC.

The authorisation with HMRC is expected to last for an 18-month period, so should not need to be repeated frequently. However, if HMRC introduce any new APIs/services, then this may require CCH OneClick to be authorised again.

Please note: once you have signed up to MTD for VAT, HMRC may take up to 72 hours to send a confirmation email.

DO NOT try to enter your VAT registration number in CCH OneClick until you have received this email, otherwise, it will fail.

Businesses that currently pay VAT by Direct Debit cannot sign up for MTD for VAT in the 7 working days leading up to, or the 5 working days after their VAT Return is due. For example, VAT return quarter-end 30th April 2019 means you have to sign up by the 18th April or wait until 9th May 2019 to sign up.
