Problem
Personal Tax: Users receive 'Invalid_Grant' or 'Invalid_Client' error when attempting to use retrieve HMRC data feature
Resolution
Please note: To use this feature you need to be on the latest version – currently Version 17.3.1 HMRC have now resolved an issue on their server, but this has caused all existing authorisation tokens to become invalid. Therefore you will need to remove any existing authorisation in your software and create a new one. To remove an existing authorisation in Personal Tax you need to: – Go to Setup and choose Authorised Agents – You can have authorisations setup at Practice Level (one for all staff) or at an individual staff level – You will need to reset whichever already exists by clicking the ‘Reset agent credentials’ button You can switch to use Practice level if you just want to go through the authorisation process once, to re-authorise you need to: – Go back to the Main Personal Tax screen and choose ‘Retrieve HMRC Data’ (on any client) and this will start the authorisation process with HMRC again. Please Note : The HMRC authorisation process does now include an identity check for security reasons. This is based upon your personal information and must be completed (just once) in order to gain access to your client’s data. You should then find that when you Retrieve the data the error no longer appears.
