Payroll Arizona: Employer Tax and Software Guide

If another founder asked me about Arizona payroll, I would tell them the state pairs one of the simplest tax structures in the country with one of the more demanding wage and hour regimes. This guide covers what Arizona requires, what changed for 2026, and how 10 payroll providers compare on price and fit.

On the tax side there is almost nothing to get wrong. No local income tax in any city or county. No state disability program. No paid family leave contribution. An unemployment wage base of $8,000, among the lowest anywhere, which caps unemployment cost at $160 per employee a year for a new employer.

The demands sit elsewhere. Employees choose their own withholding percentage rather than the employer applying a rate, and an employee who misses the five-day deadline is defaulted to a number that may be badly wrong for them. There are three different minimum wages inside the state, and one city eliminated its tip credit entirely on January 1, 2026.

Earned paid sick time accrues from the first hour worked, and the balance has to appear on every pay stub, not on request. And a late final paycheck exposes you to treble damages, meaning three times the unpaid wages.

What Arizona requires from employers

Arizona payroll taxes come down to two state obligations. Income tax is withheld at a rate each employee picks, and unemployment insurance applies to a low wage base. The rest is paperwork: one registration, a set of returns, and a payment schedule set by how much you withhold.

State income tax

Arizona moved to a flat 2.5 percent income tax in 2023, one of the lowest flat rates in the country. That figure is what an employee ultimately owes on their return. It is not, however, what the employer withholds, and confusing the two is an easy mistake in Arizona payroll setup. Withholding runs on the percentage the employee elects on Form A-4, covered in the next section.

Bonuses follow the same rule: the withholding statute covers wages, salary, bonuses, and other pay alike, so a bonus is withheld at the employee's elected percentage.

Unemployment insurance

The low wage base is the headline. Unemployment tax stops accruing once an employee crosses $8,000 in wages for the year, which for a full-time worker at the state minimum wage happens around the end of the first quarter.

New employers hold the 2.00 percent rate for at least two calendar years before the Department of Economic Security (DES) assigns an experience rating. After that, the rate follows each employer's reserve ratio (taxes paid in, minus benefits charged to the account, measured against average taxable payroll), from 0.03 percent to 8.36 percent.

Registration, returns, and reporting

One registration form covers both agencies, which is a genuine convenience compared with states that require separate applications.

How often Arizona withholding gets remitted

Filing the A1-QRT is quarterly for everyone, but paying is not. The Department of Revenue sets the payment schedule from a four-quarter average: add the Arizona tax withheld over the preceding four calendar quarters, divide by four, and recompute at the start of each new quarter.

The middle row is the one that catches a growing employer. Cross the $1,500 average and Arizona payments move onto whatever federal schedule you are already on, monthly or semiweekly, with no separate state notice. A monthly depositor that incurs a next-banking-day federal liability, meaning a federal deposit large enough to be due the next banking day, becomes semiweekly in Arizona for the rest of that quarter.

Form A-4 and the employee-elected rate

Form A-4 is the Arizona withholding election, and it is the part of Arizona payroll with no real equivalent elsewhere, because it inverts the usual arrangement.

In most states the employer applies a withholding formula to information the employee provides about filing status and dependents. In Arizona the employee simply picks a percentage of gross taxable wages, and the employer withholds exactly that. There are no allowances, no brackets, and no calculation for the employer to perform beyond multiplication.

Two consequences follow for the employer. First, the five-day deadline is short and the default is a real outcome rather than a formality: an employee whose actual liability sits closer to 3.5 percent and who never filed will be under-withheld all year and owe the difference when they file their return.

The second consequence is that the paperwork stays with you. The employee hands Form A-4 to you rather than to the Department of Revenue, so the completed forms are a record you are responsible for holding and producing if asked.

Three minimum wages and earned paid sick time

The wage floor depends on the city

Arizona has a statewide minimum wage that adjusts every January for inflation, plus two cities with their own higher ordinances. All three moved on January 1, 2026, and the state and Flagstaff rates move again on January 1, 2027.

The statewide increase of forty-five cents for 2026 came from the inflation formula in A.R.S. 23-363, tied to the Consumer Price Index between August 2024 and August 2025. Because the adjustment is automatic, there is no legislative event to watch for and the rate simply changes each January.

The A.R.S. 23-363 formula also sets the January 1, 2027 rate. The Consumer Price Index rose 3.4 percent between August 2025 and August 2026, according to the Bureau of Labor Statistics (August 2026 CPI release). That rise lifts the state rate fifty cents to $15.65 after rounding to the nearest five cents.

Where an employee works across jurisdictions in a single week, each city's rate applies to the hours worked inside it once that city's coverage threshold is met. At 2026 rates, twenty hours in Phoenix and twenty in Tucson means $15.15 for the first block and $15.45 for the second.

Earned paid sick time

Arizona has required paid sick time since July 1, 2017 under the Fair Wages and Healthy Families Act, codified at A.R.S. 23-371 through 23-381. Accrual runs at one hour for every 30 hours worked and begins at the commencement of employment.

The headcount test is not a simple snapshot. When your headcount moves above and below fifteen during the year, the 40-hour cap applies if you had fifteen or more employees on the payroll for at least part of a day in each of twenty different calendar weeks, in either the current or the preceding year. Those weeks do not have to be consecutive.

Employees exempt from overtime are assumed to work forty hours a week for accrual purposes unless their normal week is shorter.

Pay frequency and final pay

The treble damages provision is the detail that changes the risk calculation. Arizona has no state overtime statute for private employers and a light regulatory touch generally, but an employee who is paid late can recover three times the unpaid amount, which turns a modest administrative slip into meaningful exposure.

10 payroll providers for Arizona employers compared

Every provider below files Arizona state withholding and unemployment insurance. Because there is no local income tax and the withholding calculation is trivial, the differentiators here are unusual: whether the platform prints earned paid sick time on the statement, and whether it can assign different minimum wage rates by work location for employers with Tucson or Flagstaff staff.

Sick-time printing and per-location wage rates are not settled by any vendor's pricing page, and both can change with the plan tier. The table below therefore sticks to published price, multi-state cost, and trial terms, and the two Arizona questions sit on the demo checklist further down.

OnPay

OnPay sells one plan at $49 per month plus $6 per employee, with no tiers to climb; HR tools and time tracking are optional add-ons. Tax filing covers all 50 states with no multi-state surcharge, and year-end W-2 and 1099 filing sits in the base price. The company also maintains dedicated Arizona paid sick leave documentation and accrual policy setup, which is directly relevant given the pay stub disclosure requirement.

Gusto

Gusto pairs automatic tax filing and published pricing with new hire self-onboarding, digital I-9s and W-4s, and state new hire reporting on its entry plan. That plan, Simple, runs $49 per month plus $6 per employee after a base increase during 2025.

The constraint is the single-state limit on Simple. One hire in California, Nevada, or New Mexico moves you to Plus at $80 plus $12 per employee.

Patriot Software

Patriot Software offers the cheapest full-service payroll in this comparison, at every headcount in the cost table below. Full Service is $37 per month plus $5 per employee and covers federal, state, and local tax deposits and filings, while new hire reports stay with you. Basic is $17 plus $4 if you file taxes yourself, which in Arizona means handling the A1-QRT and UC-018 quarterly returns by hand.

Square Payroll

At $35 per month plus $6 per person, with multi-state payroll included, Square runs just behind Patriot on price at every headcount in the cost table. For a Phoenix or Tucson restaurant already running Square point of sale, timecard data flows straight into payroll. Hours drive both sick time accrual and the correct city wage rate, so having that data in one system removes two separate reconciliation problems.

SurePayroll

SurePayroll is sold by Paychex and built for very small employers and household employers. The Small Business plan is $29 per month plus $7 per employee, with a flat $9.99 monthly multi-state fee rather than a per-state charge.

QuickBooks Workforce Payroll

Workforce Payroll (formerly Payroll Core) is $50 per month plus $7 per employee, and the case for it still comes down to one thing: if your books live in QuickBooks Online, payroll reaches the general ledger without an export.

ADP RUN

ADP RUN is this comparison's pick for compliance depth, and every RUN package includes multi-jurisdiction payroll for staff who work in more than one state. In Arizona the harder boundary is local: assigning the correct Tucson or Flagstaff rate by work location is closer to a configuration problem than a tax one, so ask to see it set up in the demo.

The cost is opacity. ADP does not publish RUN pricing, and all four packages (Essential, Enhanced, Complete, and HR Pro) are quoted individually. Its package page does say there is no contract to sign and that service can be ended at any time.

Paychex Flex

Paychex competes on service rather than software: Paychex Flex offers the option of a dedicated payroll specialist, and its premium support adds advisors familiar with your business. Pricing is quote-only across the Basic, Foundations, Advanced, and Complete packages. The Arizona case is specific: if you have staff across Phoenix, Tucson, and Flagstaff and want someone to call when a wage rate question arises, that access has value.

Paylocity

Paylocity sits between small-business payroll and full human capital management (HCM) software, aimed at companies that have outgrown basic payroll. Its tax geolocation audits each employee's taxes against their location, and time off accruals are configured inside payroll rather than in a separate tool, which matters given the pay stub disclosure requirement. Pricing comes through a quote request with a demo rather than a published rate.

Rippling

Rippling unifies payroll, HR, and IT provisioning (setting up devices and software accounts) on one employee record. Its pricing page publishes no rates and ends in a custom quote form. Rippling's small-business page starts the platform at $8 per user per month plus a $40 monthly base fee, and its blog prices payroll as a separate module at $8 per employee billed annually or $10 billed monthly, with every other product added the same way.

What each provider actually costs an Arizona employer

The table below models published rates at three headcounts. Arizona is one of the states where these figures come close to the whole software cost, since there is no state disability program, no paid family leave contribution, and no local filings to add on top.

Patriot is the cheapest published option at every headcount, and Square runs close behind. Patriot does charge $12 per month per additional state and sells time and attendance separately, which matters more here than elsewhere because sick time accrual depends on hours data. Gusto Simple is competitive until one out-of-state hire forces the Plus tier, taking a 25-person payroll from $199 to $380 per month.

Choosing a payroll provider for Arizona

Every provider on this list files Arizona taxes, so the choice turns on five Arizona-specific questions. Ask each provider all five in the demo.

Payroll services in Phoenix

A Phoenix employer runs on the statewide rules with nothing layered on top: the state minimum wage of $15.65 from January 1, 2027 ($15.15 in 2026), no city income tax, and no municipal payroll ordinance of its own. Every provider above files for a Phoenix business, so the shortlist is the same one the rest of this guide describes.

The one genuinely local decision is whether to hand payroll to a Phoenix bookkeeping firm rather than run software yourself. A firm costs more and gives you somebody who knows your business. A platform costs less and expects you to press the buttons. Many local firms run payroll on one of the platforms above, so ask which one before paying for both.

The rest of the metro does not change the answer. Scottsdale, Mesa, Tempe, Chandler, and Glendale all sit on the state rate, so a business hiring across the valley needs no location logic at all. Add one person in Tucson or Flagstaff, though, and location-based wage rates go from irrelevant to the first thing to check in a demo.

Before you choose

FirstHR is an onboarding and HR platform, not a payroll provider. Payroll runs, payroll tax filing, and benefits administration come from the providers above, so if running payroll is the problem in front of you, one of them is the answer.

What we handle is the document layer that feeds payroll: onboarding workflows that put Form A-4, the W-4, and the I-9 on each new hire's first-day task list, e-signatures on offer letters, employee records, and document management for US small businesses at a flat $98 a month for up to 10 people or $198 for 11 to 50.

Two of the Arizona requirements above are document and workflow problems rather than payroll problems, namely getting Form A-4 completed inside the five-day window so nobody lands on the default rate by accident, and filing the new hire report within twenty days of the hire date. Both fit a task with a due date in the onboarding workflow.

Frequently Asked Questions

What are the Arizona payroll taxes an employer has to handle?

Two at the state level, plus federal: income tax withholding at the percentage each employee elects on Form A-4, and unemployment insurance on the first $8,000 of wages at 2.00 percent for new employers. There is no local income tax, no state disability program, and no paid family leave contribution.

What is Arizona Form A-4 and what happens without it?

The Employee's Arizona Withholding Election. Rather than allowances or brackets, the employee picks a flat percentage of gross taxable wages from a fixed list: 0.5 through 3.5 percent in half-point steps, or zero where the employee expects no Arizona tax liability. Without a form within five days of hire, the employer withholds at the 2.0 percent default. The employee hands the form to the employer, and a zero election has to be renewed each year by February 15.

What is the Arizona unemployment insurance wage base and rate?

$8,000 per employee for 2026, among the lowest in the country. New employers pay a flat 2.00 percent for a minimum of two calendar years, capping annual cost at $160 per person. Experienced employers range from 0.03 to 8.36 percent. Quarterly wage reports go on Form UC-018.

What is the minimum wage in Arizona?

The state rate is $15.65 an hour from January 1, 2027 ($15.15 in 2026), set each year by the inflation formula in A.R.S. 23-363. Tucson sits at $15.45 for 2026 and Flagstaff at $18.95 from January 1, 2027 ($18.35 in 2026).

Statewide and in Tucson the tip credit tops out at $3.00, leaving a tipped cash wage of $12.65 statewide from January 1, 2027 ($12.15 in 2026) and $12.45 in Tucson. Flagstaff eliminated its tip credit entirely in 2026: every employee there receives the full rate regardless of tips.

Does Arizona require paid sick leave?

Yes, under A.R.S. 23-371 through 23-381. Accrual is one hour per 30 hours worked from the commencement of employment. Employers with 15 or more employees allow up to 40 hours per year; smaller employers up to 24 hours. A 90-day waiting period before use is permitted, front-loading is allowed instead of hourly accrual, and unused time carries over subject to the annual cap.

Does earned paid sick time have to appear on the pay stub in Arizona?

Yes. The employer must record, in each regular paycheck or an attachment, the sick time available, the amount taken to date that year, and the pay received as sick time. Showing the balance only when an employee asks falls short, and so does a platform that tracks accrual internally without printing it.

How often must Arizona employers pay employees?

At least twice a month under A.R.S. 23-351, on two paydays no more than sixteen days apart and designated in advance. Monthly payroll is not permitted for most employees, which catches out employers extending a payroll calendar built in another state.

When is a final paycheck due in Arizona?

Within seven working days or by the end of the next regular pay period, whichever comes first, for a discharged employee, under A.R.S. 23-353. An employee who resigns is paid by the regular payday for the pay period in which they quit. Late payment exposes the employer to treble damages under A.R.S. 23-355, meaning three times the unpaid amount.

How long do Arizona employers have to report a new hire?

Twenty days from the date of hire, reported to the Arizona Department of Economic Security New Hire Reporting Center, with rehires counting again. Alongside it, a new Arizona hire needs Form A-4 within five days, the federal W-4 and I-9, and the written notice of rights required under the Fair Wages and Healthy Families Act.
