I need to deduct hours from monthly pay how do you do this?

Let me ensure you can follow the steps in deducting hours from your employee's monthly pay, Lozza. 

Deductions offered in QuickBooks Online (QBO) has two types. 

• After tax deductions 
  
  These types of deductions must be agreed upon in writing by the employee or be included in the employee's contract. 
   
• Loan repayments
  
  Loans given to employees for expenses such as rail tickets are not taxed.
   

Here's the steps to follow when you add/edit a deduction: 

1. Go to the Payroll and choose the applicable employee.
2. Click Actions at the top right of the page, then Deductions.
3. Enter the deduction you want to add from the list. If you can’t find the deduction you’re looking for, you can create a new one.
4. Click on the plus icon, then select Add next to the following to add the type of deduction:
   • After-tax deduction
   • Repayment
5. Once done, hit Save.
