Hello there, Central Lutheran.

Just like the previous responses of my colleagues, QBO will calculate the federal withholding taxes as long as the employee meets the taxable wage base and is set up correct. You can use this link for reference: 0.00 or no income tax withheld from paycheck.

If the same thing happens, I'd recommend reporting this to our Payroll Support Team. They can pull up your account and further review your data. 

1. Click Help in the upper-right corner and select Contact Us.
2. Enter the details of your concern and click Let's talk.
3. Select how you want to reach them and enter the necessary information to complete your request.

Or 

1. Click Help in the upper-right corner and type Talk to a human.
2. Type I still need a human and another options will appear.
3. Type those phrases repeatedly until you get this response:
   OK. Here’s a shortcut to connect with my humans.
4. Click the Contact us link and select how you want to reach them.
5. Enter the necessary details to complete your request.

We'll be right here if you need anything else.
