I'd gladly guide you in adding holiday pay in QuickBooks Online Core Payroll, mollsprings.
In QuickBooks Online Core Payroll, employers can compensate employees for time off taken as a holiday. Here's how to do this:
On the left navigation panel, go to Payroll.
On the Employees tab, select the employee.
Open the Pay Types section by clicking Start or Edit.
Tick Holiday if the option is available. If not, press the plus icon under Other earnings. Then, enter a name.
Hit Save.
Once you add a pay type to the employee's record, set a default amount for the employee. This amount will be added to the company settings, allowing you to use it for other employees as well.
