Arizona Paycheck Calculator (2026 Take-Home Pay)

Arizona applies a single 2.5% rate to taxable income, the lowest rate among the states that use a flat schedule. There are no brackets to climb and no local wage taxes, so state withholding scales in a straight line with taxable pay. The paycheck comes out of one subtraction:

The calculator makes four passes over the annual salary:

1. FICA Payroll Tax Computation: Assessed on the full gross salary, before any pre-tax deduction is subtracted. - Social Security (OASDI): 6.20% withheld on wages up to the 2026 statutory wage base ($184,500). - Medicare (HI): 1.45% withheld on all gross earnings (no wage cap), plus 0.90% Additional Medicare Tax on earnings exceeding $200,000 (single) or $250,000 (married filing jointly).
2. Federal Income Tax Withholding: Evaluated using 2026 progressive federal tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%) on gross salary less the pre-tax deduction, after applying standard deduction thresholds ($16,100 single / $32,200 married joint).
3. Arizona State Income Tax Withholding: A flat 2.5% applied to the same gross-less-pre-tax figure. No state standard deduction and no state personal exemption are subtracted first, which is why the state line here is higher than an Arizona employer would actually withhold.
4. Pay Period Proration: Annual net compensation is divided across the designated pay frequency (26 bi-weekly, 24 semi-monthly, 12 monthly, or 52 weekly pay periods).

Consider an employee in Arizona earning $75,000 annually, paid bi-weekly (26 paychecks per year), filing single, with $3,500 in annual pre-tax 401(k) contributions.

1. Gross pay per paycheck. $75,000 ÷ 26 pay periods = $2,884.62 before any withholding.
2. Pre-tax deduction. The $3,500 annual 401(k) contribution reduces each paycheck by $134.62 and also shrinks the wages used to calculate federal and state income tax; FICA is still assessed on the full gross amount.
3. FICA payroll taxes. Social Security withholds 6.2% of gross pay and Medicare withholds 1.45%, for $220.67 per paycheck.
4. Federal income tax withholding. Applying the 2026 federal schedule to the reduced taxable wage withholds $265.38 per paycheck.
5. Arizona state tax withholding. The flat 2.5% applied to the same reduced wage withholds $68.75 per paycheck.
6. Net take-home pay. $2,884.62 gross, minus $134.62 pre-tax, minus $220.67 FICA, minus $265.38 federal tax, minus $68.75 state tax leaves $2,195.19 per paycheck, equal to $57,075.00 per year, an effective total tax rate of 19.23%.

From Month Two To The Twelve-Month Total

A flat 2.5% is the lowest broad-based state rate in the country, and the cumulative view shows how little of the annual gap Arizona is actually responsible for.

Step 7 -- Two months of cumulative pay. The schedule's first row shows $6,250.00 of cumulative gross against $4,756.25 of cumulative take-home. Row two doubles both: $12,500.00 gross, $9,512.50 take-home, with $2,987.50 accumulated on the deduction side.

Step 8 -- The full year. By month twelve the schedule reaches $75,000.00 of cumulative gross and $57,075.00 of cumulative take-home, adding $4,756.25 every month without variation.

Step 9 -- What the year actually withheld. The cumulative deduction column closes at $17,925.00. That column carries the $3,500 pre-tax 401(k) contribution alongside the tax, so tax alone is $17,925.00 - $3,500 = $14,425.00, an effective total tax rate of 19.23% on $75,000.00 of gross pay.

Step 10 -- Why the monthly increment never changes. The cumulative columns advance by a constant amount each month. That is by construction: the engine caps Social Security at the $184,500 annual wage base and charges the extra 0.9% Medicare above $200,000 for a single filer, then divides the resulting annual total by twelve. The step-change a real ledger shows when Social Security stops mid-year is therefore invisible in this schedule. On $75,000 of gross the question does not arise -- neither threshold is within reach.

Sweep the salary axis and the Arizona line does nothing interesting, which is itself the finding. State withholding rises from $25.48 per bi-weekly check at $30,000 of salary to $68.75 at $75,000, $116.83 at $125,000 and $285.10 at $300,000, a perfectly straight line with no kink anywhere in it. There is no state bracket edge on this page because Arizona has no brackets. Every step in an Arizona take-home curve comes from the federal schedule or from FICA.

The federal edge that lands at $70,000 of gross salary

With the default $3,500 pre-tax deduction and the $16,100 single standard deduction, the federal 12% band is exhausted at exactly $70,000 of gross salary.

At $69,000 of salary. Take-home is $2,034.77 per bi-weekly check, federal withholding $218.46, state $62.98. Annual net is $52,904.00.

At $70,000, at the boundary. Take-home is $2,064.71 per check, federal withholding $223.08, state $63.94. Annual net is $53,682.50, so that thousand added $778.50.

At $71,000, past it. Take-home is $2,090.81 per check, federal withholding $231.54, state $64.90. Annual net is $54,361.00, and the same thousand now adds only $678.50.

The edge costs $100.00 of annual take-home on an identical raise, and Arizona is responsible for none of it: the state took $25.00 of each of those two thousands, flatly, on both sides.

The Social Security wage base at $184,500

At $184,000 of salary, annual net is $129,857.50 with FICA of $541.38 per check.

At $185,000, annual net is $130,547.00, FICA $543.13. That thousand was worth $689.50.

At $186,000, entirely above the base, annual net is $131,267.50 and FICA per check is $543.69. That thousand was worth $720.50, $31.00 more than the one below it, because the 6.2% Social Security component has stopped and only 1.45% Medicare continues.

None of that reaches the schedule. At $186,000 its twelve rows still rise by one constant increment, because FICA is settled annually before it is divided by twelve.

The marginal cost of the next $1,000

Annual net take-home is $56,396.50 at $74,000 of salary, $57,075.00 at $75,000 and $57,753.50 at $76,000. Each additional $1,000 of salary is worth $678.50 of annual take-home in Arizona, and costs $321.50 in tax. Exactly $25.00 of that cost is the state's share, at every salary, because 2.5% of a thousand does not vary.

Running the calculator backwards

Sweeping the salary axis in $500 steps at the default settings, $106,000 is the first salary at which the bi-weekly check reaches $3,000, paying $3,004.17 against $2,991.13 at $105,500. And $139,000 is the first salary whose annual net take-home clears $100,000, at $100,225.00 against $99,895.75 at $138,500. A round intermediate result worth keeping: at $125,000 of salary the bi-weekly check is exactly $3,500.00.

The pre-tax dollar, priced

At $3,500 of pre-tax deductions, annual net take-home is $57,075.00, with state withholding of $68.75 per check.

At $10,000, annual net take-home is $52,017.50, with state withholding of $62.50 per check.

Contributions rose by $6,500.00 while spendable take-home fell by only $5,057.50. The $1,442.50 difference is tax never withheld, and the whole $10,000 remains the employee's money. Arizona's flat rate makes the state portion of that saving trivially predictable: 2.5% of the extra $6,500, or $162.50 across the year.

The Total Effective Tax Rate output reads 19.23% at $3,500 and 17.31% at $10,000, falling because the contribution is excluded from that ratio's numerator, while the schedule's Cumulative Deductions column rises because it counts the contribution as a deduction. Same page, opposite direction, both correct for what they measure.

Multiplying the paycheck by 26 instead of reading the annual output. Twenty-six times $2,195.19 is $57,074.94, six cents under the engine's $57,075.00. The annual figure is computed first and the check derived from it, which is why annual net stays $57,075.00 whether you pick weekly ($1,097.60), bi-weekly ($2,195.19), semi-monthly ($2,378.13) or monthly ($4,756.25).

Reading Cumulative Deductions as a tax total. The column closes at $17,925.00 against $14,425.00 of real tax. Quoted as tax it reads 23.90% of $75,000 where the correct figure is 19.23%, overstating the burden by 4.67 percentage points.

Treating this state figure as what an Arizona employer withholds. It is not. The engine applies 2.5% with no state standard deduction and no personal exemption subtracted, so the $68.75 per check here is an upper bound on real Arizona withholding, not a match to it.

• No state standard deduction and no state personal exemption. The flat 2.5% is applied to gross less the pre-tax box and nothing else. This is the single largest source of overstatement in the state line on this page.
• No local wage taxes. Arizona cities and counties levy none on wages, and none are modelled.
• No W-4 detail. No dependents, no multiple-jobs checkbox, no extra per-period withholding, no other-income entry. Filing status is single or married filing jointly and nothing else.
• One pre-tax box, no post-tax box. 401(k), HSA and FSA contributions share one annual field with no employer match and no per-plan limit. Roth contributions, garnishments and post-tax premiums are absent.
• FICA is annual, then prorated. The twelve schedule rows never show the wage-base step at any salary, for the reason given in Step 10.
• Two definitions on one page. The effective rate output excludes the pre-tax deduction from its numerator; the Cumulative Deductions column includes it, and the gap is exactly the contribution.
