No PAYE showing on new business account

Hello, We set up a new company a few weeks ago and have been submitting weekly FPS via Sage50 payroll. Logged in to our HMRC account today to pay the 1st PAYE month and there is nothing showing. Can anyone suggest anything before I make the dreaded call to HMRC helpline? I have checked with Sage and they say that because the FPS' have gone through then HMRC must be receiving the information and the problem must be their end. Thanks

Hi,

This is a Sage50 issue as HMRC have ceased accepting RTI returns from windows 7 and 8. Impacted customers will need to complete one or more of the following options:

Upgrade their computers current operating system.
Submit using a supported operating system.
Install Sage software on a computer with a supported operating system:
Sage 50 Accounts software
Sage 50 Payroll software

Thank you.
