Frequently Asked Questions
Why do my deductions seem so high?
Federal and state taxes, FICA, and benefit premiums add up quickly. For a middle-income earner, expect:
- Federal tax: 12-22% of taxable wages
- State tax: 0-10% depending on state
- FICA: 7.65% guaranteed
- Benefits: Varies widely
What's the difference between gross and net pay?
Gross: Total earned before any deductions Net: What actually hits your bank account (gross minus all deductions)
Should I see employer contributions on my stub?
Sometimes. Employer portions of taxes (FICA, FUTA, SUTA) and benefit matches may appear for informational purposes but aren't your deductions.
Why does my YTD seem wrong?
Common causes:
- Mid-year raise or new position
- Bonus or commission that inflated one period
- Correction of prior period error
- Change in benefit elections
What if I don't recognize a deduction?
Contact your HR or Payroll department. You should understand every line item on your stub.
