Hi there tanyavanv,

It's important that all your employees are paid the right amount for the hours they've worked. QuickBooks Online is a great tool able to help you calculate and pay your employees by either cheque or direct deposit. I can point you in the right direction for assistance with payroll calculations.

For assistance with payroll deductions having too little or too much deducted, I recommend reaching out to the QuickBooks Online support team outside of the Community. They'll be able to view the pay in the system with you in a secure setting to see why the calculation is the way it is, so that it can be modified to be the right amount. You can reach them using these options:

Schedule a Callback or start a Chat: click (?)Help in the upper right > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat.
Social Media: Facebook and X / Twitter

If you have any other questions, feel free to reach out here.
