Hey Franko, I've split your post into its own thread here to differentiate it from the Payroll Premier conversation.
In regard to this message with Reckon Accounts, this will come up if you're not using a current edition of Reckon Accounts compatible with STP. One thing to check though, have you installed the latest tax table update for your 2019 edition?

Hi Rav, I have checked my edition and it is Reckon Accounts Plus 2019 Release R2 and the tax table is 1920282. In the tax table upgrade guide there was mention of release R2P and mine is simply R2. So I think my version should be compatible with STP. Regards, Franko
