T4 box 14 seem to pickup data from other years or could be a math problem.
I will do more testing tonight.
Had to go back to 2.20 today to print T4’s for client.
More info from test.
Books were converted with 2.17
Upgraded to 2.193
Upgraded to 2.20
Upgraded to 2.20.1
All t4 info works ok until 2.20.1
When I look at the employee accounts setup I now have 3 more accounts then on previous versions.
Insurable hours , pensionable earnings and insurable earnings for each employee. I also now have the government total report showing.
The t4 box 14 is now IH + PE + IE + regular salary.
