We understand the importance of accurate payroll tax calculations, suncorp. I'll provide the main key points we need to check to ensure the accuracy of employees' federal and state withholdings.

First is to review your employee’s federal (W-4) and state withholding forms (if applicable), which will determine their tax calculations based on various factors:

• How much your employee is paid
• How often your employee is paid
• Marital status
• Number of dependents
• Other sources of income

Next, check your employee's tax setup in your payroll product. Ensure that their filing status and other relevant fields align with their W-4 or state equivalent forms. If their filing status is set to Exempt or Do not withhold, taxes won't be deducted from their paycheck, regardless of their earnings. If they shouldn't be exempt from tax withholding, you can update their filing status accordingly. Please refer to this article for the complete guide: Enter federal Form W-4 in QuickBooks Payroll.
