Calculate your net paycheck in Arizona after federal taxes, the 2.5% top state income tax rate, and FICA deductions. Formula shown, sources cited β no account required.
Arizona moved to a flat income tax rate of 2.5%, one of the most aggressive tax cuts in recent state history. Every earner, regardless of income level, pays the same rate β which means a household earning the state median of $81,486 pays no more proportionally than someone earning twice that. After state and federal withholding, the median Arizona household takes home meaningfully more than workers in neighboring California or Colorado. The cost-of-living index of 110.3 puts Arizona about 10% above the national average, driven largely by housing costs in the Phoenix market. Outside the major metros, purchasing power improves significantly. The flat tax structure also simplifies planning: every additional dollar of income costs exactly 2.5 cents at the state level. Use the paycheck calculator to see your exact after-tax income and compare it to your actual Arizona living costs.
