There are two ways to create a bonus check. The easiest method to use
depends on whether you want to award the employee a particular pre-tax (gross)
amount, or a particular after-tax (net) amount.
To give a bonus based on a pre-tax (gross) amount
Include the bonus on the employee's next regular paycheck:
If you don't already have a Bonus payment type in your company payroll, set it up from the Compensation List. How?
Then when you preview the next paycheck for this employee (How do I create one paycheck and preview it?), click Add Payment or Deduction from the bottom of the paycheck and select the Bonus payment.
In the window that opens, enter the amount of the bonus in the Current box.
Intuit Online Payroll will treat the bonus as compensation and calculate the deductions.
