Federal withholding uses IRS Publication 15-T. The state line is an estimate of the statutory tax, not the state wage-bracket table, so the stub can differ.

Social Security is 6.2% up to $184,500. Medicare is 1.45%, plus 0.9% after $200,000 from one employer. Payroll programs we could verify are listed on the paycheck.

Iowa has no employee local wage tax in this calculator.
Why might my pay stub differ?
This page assumes you live and work in the same state. Reciprocity, pre-tax benefits, and a different allowance count can change the state line.
