An employee is on SMP. Her pension contribution should be 5% of qualifying earnings based on her regular salary. QB is incorrect. How can I fix the problem?

Hello Simonb1, 

Welcome to the Community page, 

Can we ask which payroll it is you are using, is it standard or advanced?

The way to tell which one you have is when you click on payroll on the main left-hand navigation bar, if you get two other tabs then that is standard if you get no other tabs showing then that is advanced when clicking on the payroll tab.
