To ensure that the Payroll Software can successfully send data to the ATO, the following environmental items need to be configured correctly:
TLS 1.2 security channel for web services is enabled by default on all involved operating systems and .NET Framework 4.8 or above is present (client, application server, SQL host server).
C:\Program Files (x86)\Wage Easy Payroll\MCS\MicropayClientServicesService.exe is allowed and can communicate to superchoice.com.au domain and 203.3.142.164 via port 443 (i.e. whitelisting in firewall, proxy, and anti-virus is required)
Please disable temporarily ALL firewall and anti-virus software on the machine and test STP reporting. For example, disable TrendMicro services and disable Windows Defender.
