How the Income Tax Calculator Is Calculated

Net income is estimated by starting from taxable income (gross income minus deductions), applying a simplified progressive federal tax estimate, subtracting FICA payroll tax at the standard combined 7.65% rate, and subtracting the state tax rate you enter.

This is a simplified single-filer estimate that excludes credits and itemized deductions — useful for a quick planning number, not a substitute for a tax professional.
