Making positive adjustments and netting to zero
Note: For more information on deductions, see the Payroll User Guide.
Sometimes, when you create an adjustment where gross pay less other deductions leaves a positive balance, you must use a wash deduction to net an adjustment to zero. For example, when you record a payment to an employee by a third party. Since you do not make this payment to the employee, the wash deduction reduces the net to zero and takes the place of what normally would be the employee's net pay.
Making an adjustment and then netting it to zero records the taxable wages for the employee, but does not affect company balances.
