Hi. I am getting the following error code when I try and submit a return to HMRC:
Hmrc Error Code: 400
Status: PERIOD_KEY_INVALID
Message: Invalid period key
I think everything is correctly set up. I go to Reports - VAT Returns. Create New VAT Return - it connects to HMRC and I get a list of open VAT obligations as currently reported by HMRC. I click “Prepare” on the one I need to complete. A VAT return is created with the Period Key 1019 which is correct.
“File VAT Return electronically to HMRC” is ticked. I click Submit Return and the error message is returned. Any ideas?
