Hello and welcome to the QuickBooks Community, Mandy
We'll be happy to share some guidance on changing contribution amounts for your employee in QuickBooks Online Advanced Payroll.
You can keep the employee on the same contribution plan and simply edit the amount of their individual contribution. To do this:
1. Go to the Employee list and click on the employee to edit
2. Select Pension settings
3. Check they are on the correct pension contribution plan
4. On the percentages for the Employee Contribution Percentage tick Override
5. Enter the percentage they want (If applicable, repeat for Employer Contribution Percentage)
6. Save
On the next payroll, the new pension amount will be calculated and submitted to Nest (if Pensionsync is active). You can also find further options for making additional contributions on the Nest site.
Thanks for reaching Intuit QuickBooks support on the Community today. We'll be around if you have any further questions!
