# How does *Arizona state income tax and unemployment insurance* work in 2026?

One flat 2.5 percent income tax. An $8,000 unemployment wage base that empties by February. A withholding form with seven boxes. Arizona is the lightest payroll state in the country.

If you are pricing where to put your next US hire on cost, Arizona is the answer most spreadsheets miss. The state takes 2.5 percent of every paycheque, full stop.

A $90,000 Phoenix hire pays roughly **$2,250 a year** in state income tax. The same hire in California pays around $8,370. Effective 1 January 2026, that gap shows up on the take-home line of every offer letter you write.

You have heard Arizona is a low-tax state. You probably haven’t seen what it actually does to a payroll line item.

This page covers the flat 2.5 percent rate, the $8,000 unemployment wage base, the seven-box A-4 withholding form, and the quarterly filing cadence.

Adding it up

## Arizona taxes every employee at the same flat rate

Arizona charges a single **flat 2.5 percent** on all taxable income under ARS § 43-1011, confirmed for 2026 by the [Arizona Department of Revenue](https://azdor.gov/sites/default/files/document/FORMS_INDIVIDUAL_2026_140iES.pdf). Every filer. Every dollar.

The flat rate has applied since tax year 2023, when the state replaced its old graduated 2.59 to 4.5 percent ladder under [SB1828 (2021)](https://www.azleg.gov/legtext/55leg/1R/bills/SB1828S.pdf). Only Indiana, North Dakota, and Pennsylvania run a comparably low single rate among states that levy income tax at all. Compare the picture in [New Mexico](/country-hiring-guides/united-states/new-mexico/state-income-tax-and-unemployment-insurance), where graduated brackets still apply, or [Nevada](/country-hiring-guides/united-states/nevada/state-income-tax-and-unemployment-insurance), which levies no state income tax at all.

David writes code for a Phoenix software company. You pay him $120,000. Arizona’s share of his annual tax bill is roughly **$3,000**. Move his job to the Bay Area and the state share climbs above $11,000.

If you run a national pay band and price total cost by US average, you are over-estimating Arizona by thousands of dollars per head.

| Filing status | Taxable income | Rate | Source |
| --- | --- | --- | --- |
| Single, head of household, married filing separately | All bands | 2.5% | ARS § 43-1011; SB1828 (2021) |
| Married filing jointly, qualifying surviving spouse | All bands | 2.5% | ARS § 43-1011; SB1828 (2021) |

### What flat rate does to payroll operations

Flat-rate withholding removes the marginal-rate maths from every payslip. The employee earning $60,000 and the employee earning $200,000 pay the same effective state rate.

There is no bracket creep. No annual indexation argument. No employee asking why the marginal rate on a bonus looks different from their normal paycheque.

The withholding system is built around a percentage election, not a bracket lookup. That is the whole reason Form A-4 has seven options instead of a wage table.

## Unemployment insurance stops paying itself by February

New Arizona employers pay **2.0 percent on the first $8,000 of wages** per employee, set by the [Arizona Department of Economic Security](https://des.az.gov/services/employment/unemployment-individual/unemployment-insurance-tax-employer-resources) under [ARS Title 23, Chapter 4](https://www.azleg.gov/arstitle/23/0004.htm). The annual cap is **$160 per head**.

After enough quarters to be experience-rated, your actual rate lands somewhere in the **0.03 to 8.36 percent** band. A high-turnover employer drifts toward the top. A stable one with few claims settles near the floor.

Jordan runs operations for a 30-person Tempe startup. Every full-time employee earning over $8,000 a year hits the SUTA cap by the end of February. After that, unemployment is zero on every paycheque until next January.

Forecast that. Your Q1 cash flow takes the whole annual UI bill in eight weeks, then nothing.

| Stage | Rate | Max per employee / year | Source |
| --- | --- | --- | --- |
| New employer (until experience-rated) | 2.0% | $160.00 | Arizona DES UIT-0603A FY2026 |
| Experience-rated, lowest step | 0.03% | $2.40 | Arizona DES UIT-0603A FY2026 |
| Experience-rated, top step | 8.36% | $668.80 | Arizona DES UIT-0603A FY2026 |
| Reserve-ratio formula authority | Cumulative contributions minus benefits, divided by average taxable payroll | Sets annual experience rate | ARS Title 23, Chapter 4 |

The $8,000 base is one of the lowest in the country. Most states have moved north of $15,000, and a handful run above $50,000. Arizona has held the line.

For a team of ten on full-time salaries, the maximum annual UI bill at the new-employer rate is $1,600. That is the entire foundation of the Arizona payroll-cost arbitrage you hear talked about at hiring offsites.

### The federal credit that pays for itself

[Federal Unemployment Tax (FUTA)](https://www.irs.gov/businesses/small-businesses-self-employed/futa-credit-reduction) starts at 6 percent on the first $7,000 of wages. Pay your state SUTA in full and on time and you get a **5.4 percent** FUTA credit, leaving an effective federal rate of **0.6 percent ($42 per employee per year)**. Colorado employers face the same credit mechanic; see how it stacks in the [Colorado state income tax and unemployment insurance](/country-hiring-guides/united-states/colorado/state-income-tax-and-unemployment-insurance) guide.

Late or partial SUTA erodes the credit. Pay on the wire by the due date and the FUTA bill effectively rounds to nothing. Miss it, and you owe the full 6 percent.

## What is Form A-4?

[*Form A-4*](https://azdor.gov/forms/withholding-forms) is Arizona’s Employee’s Withholding Election, administered by the [Arizona Department of Revenue](https://azdor.gov). Think of it as the state version of the federal W-4, but built around one percentage instead of allowances.

Every new hire completes one within **5 days of starting**. The 2026 form offers seven options: **0.5, 1.0, 1.5, 2.0, 2.5, 3.0, or 3.5 percent**. If the employee files no form, you withhold at the **2.0 percent default** until they choose.

Sofia leads sales for a Tucson SaaS team. On day one she ticks the 2.5 percent box on her A-4. That matches the flat state rate exactly, so her annual withholding lands at roughly zero balance due, zero refund.

If Sofia takes the path of least resistance and skips the form, she defaults to 2.0 percent and ends up owing Arizona at filing.

| Election | Effect | Useful when |
| --- | --- | --- |
| 0.5% to 2.0% | Under-withholds. Employee will owe Arizona tax at filing. | Large itemised deductions, dependent credits, other tax-reducing positions. |
| 2.5% | Exact match to flat rate. Roughly zero balance due, zero refund. | Default-aligned election for most full-time employees. |
| 3.0% to 3.5% | Over-withholds. Employee receives an Arizona refund. | Treating withholding as forced savings. |
| Add flat dollar amount | Same form. Adds a fixed extra deduction on top of the percentage. | Side income that needs covering. |

### The annual refresh nobody remembers

An ordinary percentage election rolls over. The one that does not is the zero-rate election: an employee claiming exempt from Arizona withholding has to renew it every year.

The duty sits with the employee, not with you. To keep the exempt election for the next taxable year they must complete a new A-4 and give it to you by **15 February** of that year, per the [Employer’s Instructions for Arizona Form A-4](https://azdor.gov/sites/default/files/document/FORMS_WITHHOLDING_2026_A-4i.pdf). No new form by that date and you simply revert them to the 2.0 percent default.

### The 5-day default trap

The 2.0 percent default is lower than what most full-time employees actually owe at the 2.5 percent flat rate. A new hire who skips A-4 in week one is under-withheld for the months it takes to notice. They owe Arizona at filing.

The fix is to capture A-4 in onboarding alongside Form I-9 and the federal W-4, in a single digital signing session. The default never fires. The employee makes an informed choice before their first payroll runs.

## How does an Arizona employer file withholding?

Three forms cover the lifecycle. **Form A1-QRT** reconciles each calendar quarter. **Form A1-WP** is the deposit voucher for employers not on EFT. **Form A1-R** is the annual reconciliation, due **31 January**.

All Arizona withholding returns must be filed electronically through [AZTaxes.gov](https://www.aztaxes.gov). The paper option has been off the table since the 2019 tax year.

Arizona Filing Cadence

Three state forms cover the lifecycle. Deposit cadence mirrors the federal schedule and depends on the average liability across the four-quarter look-back. Filing of the quarterly return itself is universal, no matter how often you deposit.

A1-QRT · quarterly return (all employers)

A1-WP · deposit voucher (non-EFT)

A1-R · annual reconcile 31 Jan

AZTaxes.gov · e-file mandate

| Form | What it is | Frequency | Due |
| --- | --- | --- | --- |
| Form A1-QRT | Arizona Quarterly Withholding Tax Return | Quarterly (every employer) | 30 April, 31 July, 31 October, 31 January |
| Form A1-WP | Payment of Arizona Income Tax Withheld (deposit voucher, non-EFT) | Per deposit (quarterly, monthly, semi-weekly, or one-banking-day) | By deposit due date |
| Form A1-R | Arizona Withholding Reconciliation Return, plus W-2 / 1099-R copies | Annual | 31 January following the tax year |
| Form A1-APR | Annual Payment Withholding Tax Return (small employers only, with prior approval) | Annual | 31 January |

### Deposit cadence is federal-aligned

Arizona uses the federal four-quarter look-back to set deposit cadence. Employers with average quarterly liability under $1,500 deposit quarterly. Average $1,500 to $50,000 puts you on monthly. Above $50,000, semi-weekly.

A single deposit obligation of $100,000 or more on any one payday triggers the next-banking-day rule, the same trigger as federal. The A1-QRT still reports the quarter even when you are on a semi-weekly deposit schedule.

### The zero-filing rule

A quarterly filer with zero Arizona withholding for the period still files a zero A1-QRT. Skip it and AZTaxes flags a missing return, then starts the delinquency clock.

Annual A1-R is required even in a zero year if you were active for any part of it.

## Do Arizona cities or counties charge a local payroll tax?

No. Arizona has no city or county tax on payroll. There is no equivalent of Birmingham’s occupational tax, Philadelphia’s wage tax, or New York City’s local income tax.

Withholding registration is state-only via the Arizona Joint Tax Application. Cities collect Transaction Privilege Tax, which is a sales-tax variant on business activity, not a payroll deduction.

| Tax type | Levied on | On payroll? | Source |
| --- | --- | --- | --- |
| Arizona state income tax | Employee wages | Yes, 2.5% flat | ARS § 43-1011 |
| City income tax | None levied | No | Arizona Department of Revenue |
| County income tax | None levied | No | Arizona Department of Revenue |
| Transaction Privilege Tax (TPT) | Seller’s gross receipts on taxable business activity | No | ARS Title 42, Chapter 5 |

Three things to keep straight on Arizona local tax:

- **TPT is not payroll.** Phoenix charges 8.6 percent combined state-plus-city on business receipts. Tucson levies 2 percent at city level. None of it appears on a payslip.
- **Local minimum wages exist.** Flagstaff and Tucson run higher floors than the state. Phoenix uses the state figure. The [Arizona wages and overtime page](/country-hiring-guides/united-states/arizona/wage-overtime-and-meal-break-law) covers the city table.
- **One registration covers payroll.** The Joint Tax Application registers you for state withholding and state unemployment in a single filing. No separate city payroll registration.

For multi-state employers, the absence of city payroll tax is a real operational simplification. Pennsylvania has dozens of municipalities running local Earned Income Tax. [Alabama](/country-hiring-guides/united-states/alabama/state-income-tax-and-unemployment-insurance) has Birmingham, Bessemer, and Gadsden each levying their own city occupational tax. Arizona payroll is one state return, one state UI filing, one federal stack.

## What is the Arizona minimum wage and overtime rule in 2026?

Arizona’s state minimum wage in 2026 is **$15.15 per hour**, indexed to inflation every January. Two cities run higher floors: **Flagstaff at $18.35** and **Tucson at $15.45**.

Overtime defers entirely to federal: **1.5x regular rate** for non-exempt hours over 40 in a workweek. Arizona adds no state daily-overtime premium and no double-time rule.

| Jurisdiction | 2026 minimum wage | Annual indexation |
| --- | --- | --- |
| Arizona (state floor) | $15.15 / hour | CPI-W, every 1 January, under Proposition 206 (2016) |
| Flagstaff | $18.35 / hour | Greater of state plus $2 or local CPI, under Flagstaff Minimum Wage Act |
| Tucson | $15.45 / hour | Scheduled steps under Tucson Proposition 206 ordinance |
| Federal floor | $7.25 / hour | Static since 2009, 29 USC § 206(a)(1) |
| Federal overtime rule | 1.5x regular rate over 40/week | 29 USC § 207 (FLSA) |

Because Arizona indexes annually with CPI, the state minimum has moved up every January since 2017. The Industrial Commission of Arizona publishes the new rate in October each year for the following January.

If you are running a Flagstaff or Tucson hire, geocode the work location. A state-floor wage paid to an employee actually working inside Flagstaff is a back-wage liability the moment payroll runs.

### Why Arizona has no daily-overtime layer

Arizona never adopted a state overtime statute. Non-exempt employees earn the federal 1.5x premium for hours over 40 in a workweek, and that is the full story.

Exempt employees are exempt under the federal duties tests: executive, administrative, professional, computer, outside-sales. No California-style daily-8 rule, no seventh-day premium, no alternative workweek vote.

## How Teamed runs Arizona payroll end to end

Teamed becomes your legal employer of record in Arizona for [a flat from $599 per employee per month](/pricing).

You hire the person. We register them, capture Form A-4 on day one (so the default is designed not to fire), run payroll on the federal-aligned cadence, file every state return, and apply Flagstaff or Tucson minimum-wage rules at the geocoded work location. Paid leave accrual under the [Arizona paid family and sick leave](/country-hiring-guides/united-states/arizona/paid-family-and-sick-leave) rules runs in parallel. Termination payments follow the at-will rules covered in the [Arizona termination and at-will exceptions](/country-hiring-guides/united-states/arizona/termination-law-and-at-will-exceptions) guide.

Zero FX mark-up. Statutory employer cost passes through itemised on every invoice.

What an Arizona hire through Teamed looks like, day to day:

- **Day 0.** The Arizona Joint Tax Application registers the employer with the Department of Revenue (withholding) and Department of Economic Security (unemployment) in one filing. Teamed’s US entity (Teamed US Inc., Delaware) is the legal employer of record.
- **Day 1.** Employee onboarded with Form A-4 (percentage chosen, not defaulted), federal W-4, and Form I-9 in a single digital signing session. New-hire reporting filed with the Department of Economic Security within 20 days of start.
- **Ongoing.** Deposits run quarterly, monthly, semi-weekly, or one-banking-day per the federal-aligned schedule. A1-QRT files at end of every quarter regardless. FICA, FUTA, SUTA, state income tax all calculated and remitted. Multi-state day-count ledger maintained for any employee who travels.
- **Year end.** Form A1-R reconciliation filed by 31 January with all W-2 copies. Exempt-election renewals chased and collected by 15 February, and anyone who misses the date reverts to the 2.0 percent default. Annual rate notice from Economic Security received and applied to the next year’s SUTA.

Pricing is one number per employee per month, in any currency you pay us in, with no FX mark-up between your billing currency and the US dollars Teamed remits to the State of Arizona. Statutory employer cost passes through at cost, itemised on the invoice.

Behind the platform sit real HR and legal experts with deep local employment-law expertise, including a US employment specialist and a payroll lead who knows the Arizona quarterly cadence, the Flagstaff and Tucson minimum-wage geocoding, and the SUTA-cap forecasting that concentrates UI cost in Q1. When something looks off on a payslip, you reach an actual person, not a chatbot or a pooled queue.

Contractor onboarding, EOR payroll, and entity graduation all live on one platform. An Arizona contractor who converts to W-2 keeps their record. That same employee can graduate from EOR to your own Delaware C-corp without changing systems. One timeline. One platform.

### When EOR is the right call (and when it isn’t)

EOR works while you’re testing the Arizona market, ramping a small remote team, or running one or two Arizona hires alongside a larger US payroll elsewhere.

Once you have six or more Arizona employees and predictable hiring ahead, the maths of running your own US entity starts to win. Arizona has no city payroll tax to register for, so the registration burden is lighter than Pennsylvania or Alabama. Teamed’s [Crossover Calculator](https://www.teamed.global/tools/crossover-calculator) tells you the month the EOR model stops being right. The conversation is built into the relationship.

Teamed Client Operations

Arizona is the simplest state we run payroll in. One flat 2.5 percent income tax, no city payroll layer, A-4 is one percentage box. The trap is the 5-day default. A new hire who skips the form gets withheld at 2 percent automatically, and that’s under what most people actually owe. We capture A-4 in onboarding day one. The default never fires.

A note from Tom Price-Daniel

The 2.5 percent flat rate is not the number that bites. The 2.0 percent default is.  
Skip Form A-4 in the first 5 days and the employee under-withholds for every payroll that follows, plus anyone claiming exempt must hand you a fresh form by 15 February each year or drop to the default.  
Two deadlines. One box. No margin.
