Taxable Income = Gross Salary – Pre-Tax Deductions (401k, HSA, Health Insurance)
Federal Tax = Progressive brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%)
Iowa State Tax = (Taxable Income – Iowa Standard Deduction) × 4.82%
Iowa Standard Deduction (2025) = $5,000 (single) or $10,000 (married)
FICA = 7.65% (6.2% SS + 1.45% Medicare)
Net Pay = Gross – (Federal + Iowa State + FICA + Pre-Tax)
