Frequently Asked Questions

How do employee business expenses get treated?

Model on Form 2106 (or 2106-EZ) where applicable.

Does the calculator include employer payroll taxes?

No—these results show employee withholding only; employer FICA and FUTA are separate.

Are employer payroll taxes deducted from employee pay?

No. These are separate costs paid entirely by the employer.

What if I get a mid-year raise?

Update your inputs to reflect new annualized income; withholding adjusts proportionally.

Why does the monthly view differ from my payslips?

We default to 1/12. Day-based payroll (28–31 days) creates small month-to-month differences.
