At this level most of your income falls in the 10% and 12% federal brackets after the standard deduction. Contributing to a 401(k) or HSA lowers the income that's taxed (though not the Social Security and Medicare portion), so pre-tax deductions are one of the few levers that noticeably change take-home pay here.
Arizona note: Flat 2.5%. Arizona's standard deduction conforms to the federal standard deduction by statute (2026 federal amounts applied). Arizona has no separate personal exemption.
