$45,000 After Taxes in Arizona (2026)

A single filer paid $45,000 in Arizona has $28,900 of federal taxable income after the $16,100 standard deduction. The top slice of that income falls in the 12% federal bracket, which starts at $12,400 of taxable income, and federal income tax comes to $3,220, or 7.16% of the salary.

Payroll tax is federal and the same in Arizona as everywhere else: on $45,000 of wages it is $3,443, made up of $2,790 of Social Security at 6.2% of every dollar and $653 of Medicare at 1.45%.

Arizona taxable income is $29,250, and Arizona taxes it at its flat 2.5% rate. State income tax is $731, 1.63% of the salary. Arizona has a single flat rate of 2.5% on all taxable income, the lowest flat individual income tax rate in the country alongside North Dakota's top rate.

Altogether $7,394 of a $45,000 Arizona salary goes to tax, an effective total rate of 16.43%, which leaves $37,606 a year: $3,134 a month, $1,446 every two weeks, $723 a week, or $18 an hour over 2,080 hours.

At $45,000, Arizona ranks 12th of 51 jurisdictions for take-home pay, highest first. A no-tax state leaves $731 more a year, and the median state $540 less than Arizona. The lowest take-home at $45,000 is $35,518, in Oregon, $2,088 less than in Arizona.

Across the state line the same $45,000 leaves a single filer: California $37,589, $17 less; Nevada $38,338, $731 more; Utah $36,959, $647 less; Colorado $37,066, $540 less; New Mexico $37,370, $236 less.

These Arizona figures treat the whole $45,000 as wages, take the standard deduction, claim no dependents and include no federal credits. A pre-tax 401(k) contribution or health premium would lower taxable income and raise take-home; a second income or itemized deductions would change it again.
