Arizona Tax Preparer Requirements 2025-2026

Arizona is one of the simplest states in which to start a tax preparation business. No state license is required, no surety bond, no state-mandated continuing education, and no exam to pass. A federal PTIN at $18.75 per year is the only formal requirement. What Arizona does have is a 2.5% flat income tax rate, 100% military retirement exclusion, a complete Social Security exemption, a dollar-for-dollar charitable credit stack worth up to $3,131 for married filers, a major snowbird and retiree client base, and one of the most consequential tax law uncertainties of the 2026 filing season: the unresolved OBBBA conformity dispute. As of the date of this guide, no Arizona statute has been enacted to adopt the federal tip income deduction, overtime deduction, auto loan interest deduction, or $6,000 senior deduction from the One Big Beautiful Bill Act (OBBBA). Governor Hobbs issued Executive Order 2025-15 directing ADOR to place these items on Form 140, but two conformity bills have been vetoed and the legal authority remains contested. This guide covers every requirement Arizona paid preparers need to know for TY2025 returns filed in 2026.

Does Arizona Require a State Tax Preparer License?

Arizona does NOT require non-credentialed paid tax preparers to obtain a state license, pass an exam, post a surety bond, or register with the Arizona Department of Revenue (ADOR). There is no Arizona preparer registration program for non-credentialed individuals. Any person who obtains a federal PTIN may legally prepare Arizona individual income tax returns for compensation.

ADOR retains authority to suspend a preparer's e-file privileges for violations such as filing inaccurate returns, claiming credits clients do not qualify for, or engaging in fraud. But this is an enforcement action taken after a violation, not a licensing gate that applies before a preparer can work.

What Non-Credentialed Preparers Can and Cannot Do

Non-credentialed preparers may prepare individual and business Arizona returns (Form 140, Form 140PY, Form 140NR, and all supporting schedules), provide tax planning advice, and represent clients before ADOR in writing. They may NOT use the titles CPA, PA, or EA, and they may not represent clients before the IRS in examination or collection matters beyond returns they personally prepared, unless they have earned the IRS Annual Filing Season Program (AFSP) Record of Completion.

The AFSP Record of Completion is a voluntary credential requiring 18 hours of CE annually (including a 6-hour Annual Federal Tax Refresher course). It does not convert a non-credentialed preparer to a licensed status, but it does grant limited IRS representation rights and signals professional commitment to clients. Enrolled Agents (EA) require passing the 3-part IRS Special Enrollment Exam and 72 CE hours every three years, and have unlimited IRS representation rights.

PTIN: The Only Mandatory Requirement

2026 PTIN fee: $18.75 ($10.00 IRS base fee plus $8.75 third-party contractor fee). This is the IRS-published figure; some third-party sources have cited $19.75, which is incorrect. Renew annually by December 31 at irs.gov/ptin. Renewal takes approximately 15 minutes online. Your PTIN must appear on every paper return you prepare and on the electronic records for every return you e-file.

An EFIN (Electronic Filing Identification Number) is required if you plan to e-file Arizona returns through the IRS Fed/State e-File program. Arizona does not issue a separate state EFIN. Apply through IRS e-Services. Note that Arizona mandates e-filing for fiduciary, partnership, and corporate returns (tax year 2020 forward), but there is no volume-based e-file mandate for individual income tax returns at the Arizona state level. The federal IRS rule requires e-filing if you expect to file 11 or more covered returns in a calendar year.

FTC Safeguards Rule (WISP)

Every paid tax preparer, including solo practitioners in Arizona, must maintain a Written Information Security Plan (WISP) under the Gramm-Leach-Bliley Act (15 U.S.C. 6801(b)). Required elements include a designated responsible individual, multi-factor authentication (MFA) for all systems containing customer information, a documented risk assessment, and an incident response plan. FTC penalties reach up to $46,517 per violation per day. A free WISP template is available at IRS Publication 5708.

OBBBA Conformity: Critical Practice Alert for TY2025

This is the most consequential compliance issue for Arizona preparers in the 2026 filing season. Read this section carefully before filing any TY2025 Arizona return that claims tip income, overtime, auto loan interest, or the $6,000 senior deduction.

Arizona Uses Static Conformity

Arizona conforms to the Internal Revenue Code as of a fixed reference date. For tax years beginning in 2025, that date is January 1, 2025. Arizona does not automatically adopt new federal tax legislation. When Congress enacts a tax law change, Arizona requires a separate state legislative action to update its conformity date and adopt those changes.

The OBBBA (One Big Beautiful Bill Act) was signed into federal law on July 4, 2025, after Arizona's January 1, 2025 conformity date. Arizona therefore does not automatically conform to any OBBBA provision. Legislative action is required for each provision to take effect in Arizona.

Executive Order 2025-15: Five Provisions on Form 140

On November 25, 2025, Governor Hobbs issued Executive Order 2025-15 directing ADOR to incorporate five OBBBA provisions on Arizona Form 140 for TY2025:

1. Increased standard deduction ($15,750 single / $23,625 HOH / $31,500 MFJ)
2. $6,000 additional senior deduction for taxpayers age 65 or older (income-limited)
3. Tip income deduction (IRC Section 224, up to $25,000)
4. Overtime pay deduction (IRC Section 225, up to $12,500 single / $25,000 MFJ)
5. Qualified vehicle loan interest deduction

These provisions appear on Form 140 by executive order, not by statute. That distinction matters: the governor cannot enact tax law by executive order under the Arizona Constitution, and the Arizona Legislature has refused to pass conformity legislation on the governor's terms. Two conformity bills were vetoed by Governor Hobbs (January 16, 2026 and February 13, 2026). As of the date of this guide, no conformity statute has been enacted.

Provision-by-Provision Status (June 2026)

What This Means for Your Practice

Clients who claimed the tip deduction, overtime deduction, auto loan interest deduction, or $6,000 senior deduction on their TY2025 Form 140 based on the Executive Order instructions may face Arizona amended return requirements if conformity legislation is ultimately rejected or enacted with different terms. ADOR has stated that penalty relief will apply in that scenario, but the underlying liability would remain due.

Recommended practice steps:

• Document your reasoning for any EO-sourced deduction claimed on a client's return.
• Advise clients who claimed these deductions that the legal authority is contested and that an Arizona amended return may be required depending on the outcome of ongoing budget and conformity negotiations.
• Preserve the client's amendment flexibility through the October 15, 2026 extended deadline.
• Do NOT describe tips, overtime, auto loan interest, or the $6,000 senior deduction as confirmed Arizona law in any client-facing communication.
• Monitor ADOR news releases and the Arizona Legislature for resolution; conformity may be addressed in the ongoing budget package.

For agriculture, construction, and equipment-heavy clients who took 100% federal bonus expensing under OBBBA, the Arizona position on that deduction is also unresolved. This is the most significant dollar-value uncertainty for those clients, and preparer documentation of approach is essential.

Arizona Individual Income Tax for TY2025

Flat 2.5% Rate

Arizona taxes all individual income at a flat 2.5% rate, effective January 1, 2023. The rate applies to all filing statuses, all income levels, and all income types. There are no brackets, no surtax, and no income threshold above which a higher rate applies. The Proposition 208 surcharge (a 3.5% add-on proposed by 2020 voter initiative for incomes above $250,000 single / $500,000 MFJ) was struck down by the Arizona Supreme Court on March 11, 2022, and is no longer applicable.

SB 1318 proposed reducing the flat rate from 2.5% to 2.42% for tax year 2026, tied to a structural surplus formula. As of the date of this guide, SB 1318 was NOT enacted. The rate for TY2025 and TY2026 remains 2.5%.

Arizona does not have a state alternative minimum tax (AMT). No separate AMT computation is required on the Arizona return.

Standard Deduction (TY2025)

Arizona's standard deduction is indexed to the federal standard deduction methodology under ARS 43-1041. For TY2025:

• Single / Married Filing Separately: $15,750
• Head of Household: $23,625
• Married Filing Jointly / Qualifying Surviving Spouse: $31,500

Seniors age 65 or older receive an additional standard deduction above the base amounts:

• Single / Head of Household age 65+: additional $2,000 (or $4,000 if also legally blind)
• MFJ / MFS / Qualifying Widow(er) age 65+: additional $1,600 per qualifying person (or $3,200 if also blind)

The $6,000 additional senior deduction that appears on Form 140 (from EO 2025-15) is a separate item from the standard deduction age add-on described above. As noted in the OBBBA section, the $6,000 EO item does not have statutory authority as of the date of this guide.

Personal Exemptions and Special Subtractions

Arizona does not have a broad per-filer personal exemption equivalent to the historical federal personal exemption. Instead, Arizona provides targeted subtractions and credits:

• Age 65+ subtraction: $2,300 per qualifying taxpayer or spouse
• Blind taxpayer subtraction: $1,500
• Dependent credit (not deduction): $100 per dependent under age 17; $25 per other dependent

There is no broad Arizona personal exemption deduction parallel to the pre-2018 federal $4,050 personal exemption.

Capital Gains

Arizona taxes capital gains at the standard flat 2.5% individual rate. There is no preferential Arizona capital gains rate. Long-term and short-term gains are both taxed at 2.5%, without the federal rate distinction (0%, 15%, 20%). A limited subtraction may apply for capital gains from the sale of certain Arizona small business stock under ARS 43-1022, but this is narrow in scope. Clients holding investment portfolios or real estate will pay Arizona tax at 2.5% on all gains.

Arizona Retirement Income: What Is and Is Not Exempt

Arizona offers some of the most favorable retirement income treatment in the country, but the rules differ sharply by income type. Getting these distinctions right is high-stakes for retiree clients.

Military Retirement: 100% Excluded, No Cap

All benefits, annuities, and pensions received as retired or retainer pay from any U.S. Armed Forces branch (Army, Navy, Air Force, Marine Corps, Coast Guard, Space Force) are 100% excluded from Arizona income tax under ARS 43-1022(26). This exclusion applies to the full dollar amount regardless of how large the pension is. There is no dollar cap and no income test.

Important correction: Some older websites and third-party sources cite a $3,500 cap for Arizona military retirement. That figure was the limit that applied in tax years 2019 through 2020. The full exclusion with no dollar cap took effect for tax years beginning January 1, 2021. If you encounter the $3,500 figure in your software or reference materials, it is outdated and incorrect for TY2025.

If both spouses each receive military retirement income, each subtracts 100% of their own amount independently. The Survivor Benefit Plan (SBP) annuity paid to surviving spouses is taxable under federal law; Arizona follows federal treatment on SBP taxability.

Federal Civilian Pension (CSRS/FERS): Up to $2,500 Subtraction Only

Federal government retirees under CSRS (Civil Service Retirement System) or FERS (Federal Employees Retirement System) receive only a partial exclusion. Arizona allows a subtraction capped at $2,500 per year under ARS 43-1022(2)(a). This is not a full exclusion. A federal employee retiring with a $40,000 annual CSRS pension can subtract only $2,500 from Arizona gross income; the remaining $37,500 is taxable at 2.5%.

This distinction matters enormously when advising clients comparing military retirement against federal civilian retirement from a state tax standpoint. A military retiree with the same pension dollar amount pays zero Arizona tax on retirement income; a CSRS or FERS retiree owes Arizona tax on virtually all of it.

Arizona state and local government pensions (ASRS, CORP, PSPRS, and similar plans) carry a similar $2,500 subtraction cap under ARS 43-1022(2)(b). Private pensions, IRA distributions, and 401(k) distributions receive no special exclusion and are taxed at the full 2.5% rate.

Social Security: 100% Excluded, No Income Limit

Arizona does not tax Social Security benefits. Under ARS 43-1022(10), the amount included in federal AGI under IRC Section 86 is subtracted in full from Arizona gross income. Because Arizona starts from federal AGI (which includes the taxable portion of Social Security up to 85%), this subtraction removes the entire taxable SS amount from Arizona's calculation. The exclusion applies regardless of income level; there is no phase-out or income threshold.

Railroad Retirement Act benefits receive identical treatment under the same statute.

Arizona Charitable Tax Credits: The Dollar-for-Dollar Stack

Arizona's charitable credit system is one of the most powerful tax planning tools available to Arizona residents. These are dollar-for-dollar nonrefundable credits directly against Arizona income tax liability, not deductions. A client who itemizes and also takes Arizona charitable credits receives a federal deduction AND an Arizona dollar-for-dollar credit for the same contribution, depending on the category.

All credits in this section have an extended contribution deadline: donations made up to April 15, 2027 can be applied against TY2026 Arizona tax liability. This allows post-year-end tax planning once you know the client's exact Arizona tax bill.

The two STO credits (Forms 323 and 348) stack. A married couple can contribute up to $3,131 total to private school tuition organizations and claim a full dollar-for-dollar Arizona credit. Combined with the QCO credit ($1,009), a married couple can potentially offset up to $4,140 in Arizona tax liability through charitable contributions alone, before accounting for the foster care and public school credits.

All credits are nonrefundable: they can reduce Arizona tax liability to zero but cannot generate a refund. Contributors must give to certified organizations; direct donations to schools do not qualify for the STO credits. Both STO credits require the contribution to go to an ADOR-certified School Tuition Organization, which then allocates scholarships to eligible students.

Property Tax Credit (Form 140PTC): Refundable Credit for Low-Income Seniors

Arizona provides a refundable income tax credit for qualifying low-income residents who are either age 65 or older, or who receive Title 16 Supplemental Security Income (SSI), and who paid property taxes or rent on their Arizona primary residence during the tax year.

For TY2025 filings in 2026:

• Income threshold (single-person household): $47,712
• Income threshold (two or more persons in household): $59,640
• Maximum credit: $502 (refundable)

Renters must obtain a signed Arizona Form 201 from their landlord documenting the property tax portion of rent. The 140PTC is one of the few refundable Arizona credits and is particularly valuable for fixed-income seniors whose Arizona tax liability is zero.

Pass-Through Entity Tax (PTET) and SALT Cap Planning

Arizona has enacted a Pass-Through Entity Tax (PTET) election for partnerships and S corporations. Under the PTET election, the entity pays Arizona income tax at 2.5% at the entity level. That entity-level payment is a deductible business expense for federal purposes and is not subject to the individual SALT cap, creating a workaround for high-income pass-through owners.

Individual partners or shareholders receive a corresponding Arizona credit to prevent double taxation. Arizona requires the entity to give members 60 days' written notice of the PTET election and allows individual members to opt out.

The OBBBA temporarily increased the federal SALT cap to $40,000 for 2025 ($40,400 for 2026) for taxpayers below an income phase-out. This reduced but did not eliminate the PTET benefit for highest-bracket Arizona taxpayers. For clients with Arizona pass-through income above the SALT cap threshold, the PTET election remains worth analyzing. Arizona state income tax at 2.5% is relatively modest, so the PTET benefit is most material when the client also has income in other states with higher tax rates.

Arizona Transaction Privilege Tax (TPT): What Preparers Need to Know

Arizona's Transaction Privilege Tax is a privilege tax levied on vendors for the right to conduct taxable business activities in the state. It is functionally similar to a sales tax, though the legal incidence falls on the seller rather than the buyer. The state base rate is 5.6%. Combined state and local rates range from approximately 8.05% (Scottsdale) to 11.2% depending on the city and county.

Tax Preparation Services Are NOT Subject to TPT

Tax preparation services are not subject to Arizona TPT. Arizona's TPT applies only to specifically enumerated business classifications (contracting and construction, restaurant and food service, commercial lease, tangible personal property rental, amusement, publishing, and others). There is no "professional services" classification in Arizona's TPT framework. Tax preparation, bookkeeping, and tax consulting are professional services where the deliverable is human expertise, not tangible property, and are outside the taxable base.

An independent Arizona tax preparer does not need to collect or remit TPT on fees charged for preparation services. If you also sell tangible goods (software packages, printed forms, supplies), the tangible property sale may trigger a separate TPT obligation.

Short-Term Rentals and TPT: A High-Frequency Client Issue

Residential rental income from rentals of fewer than 30 consecutive days IS subject to Arizona TPT under the transient lodging classification. Clients with Airbnb, VRBO, or other short-term rental properties in Arizona must register for TPT with ADOR and collect and remit TPT on short-term rental income. This is one of the more common compliance gaps for Phoenix, Scottsdale, and Tucson property owners who started renting short-term through platforms without understanding the TPT obligation. Long-term residential rentals (30 days or more) are exempt from TPT.

Arizona Military Tax Rules: Active Duty and Retirees

Arizona is home to six major military installations: Luke AFB (Glendale), Davis-Monthan AFB (Tucson), Fort Huachuca (Sierra Vista), Yuma Proving Ground, MCAS Yuma, and Luke's satellite training at other West Valley locations. Each installation generates a distinct client population with different tax profiles.

Active-Duty Pay and Domicile

Arizona does not tax active-duty military pay for personnel whose state of legal residence (domicile) is a state other than Arizona. Servicemembers stationed at Arizona installations but domiciled elsewhere use DD Form 2058 to establish their state of legal residence with their payroll office. Arizona taxes active-duty pay only if Arizona is the servicemember's legal domicile.

Basic Allowance for Housing (BAH) and Basic Allowance for Subsistence (BAS) are excluded from income both federally and under Arizona law. Combat zone exclusion applies for all months serving in a designated combat zone; Arizona conforms to the federal exclusion.

Guard and Reserve drill pay is taxable. Annual training pay is taxable unless the training occurs in a designated combat zone.

Military Spouse Residency Relief Act (MSRRA)

Under the MSRRA, military spouses may elect to use the servicemember's state of legal residence for income tax purposes. A spouse who is legally domiciled in Texas (a no-income-tax state) and accompanies their servicemember spouse to Davis-Monthan AFB can file in Texas rather than Arizona, provided the spouse has not taken actions that establish Arizona domicile independently (such as obtaining an Arizona driver's license or registering to vote in Arizona). This is a frequently missed planning opportunity and a significant source of tax savings for military families at Arizona installations.

Transition to Retirement: The Key Conversation

Separating servicemembers who plan to retire to Arizona and collect military retirement are often surprised that Arizona taxes none of their retirement pay. A client transitioning from active duty to retirement with a $60,000 annual pension, combined with $20,000 in Social Security and $10,000 in VA disability compensation, owes zero Arizona income tax on all three income streams. That planning story, told clearly, is the strongest reason for a military-adjacent Arizona practice to position itself as the specialist for transition planning.

High-Value Arizona Client Niches

California, Oregon, and Washington Snowbirds and Retirees

The Phoenix and Scottsdale metros attract one of the largest concentrations of high-net-worth California, Oregon, and Washington retirees and part-year residents in the country. These clients arrive with:

• Domicile transition complexity: Abandoning California domicile requires severing the California Franchise Tax Board's residency factors (voter registration, driver's license, bank accounts, professional associations, social ties, business interests). California aggressively audits claimed domicile changes for high-income taxpayers. Oregon and Washington have similar enforcement postures for different reasons.
• California-source income carve-outs: Even after successfully establishing Arizona domicile, California taxes income sourced from California (rental income from California property, income from California-based S corps or partnerships, deferred compensation from California employers). Arizona allows a credit for taxes paid to other states, but preparing both returns correctly requires understanding how each state defines source income.
• Part-year returns: Arizona Form 140PY for the year of the move. The prior state return is required for income earned in that state during the transition year.
• Snowbirds under 183 days: Clients spending fewer than 183 days per year in Arizona and maintaining a California residence remain California residents for tax purposes even if they claim Arizona as their primary home for other reasons. These clients often require both an Arizona nonresident return and a California resident return.

Tech Sector: ASU Research, Intel, TSMC, GoDaddy

Arizona's growing tech corridor (Chandler, Tempe, Scottsdale) employs large populations of highly compensated employees at Intel, Taiwan Semiconductor Manufacturing Company (TSMC's new Fab 21), GoDaddy, and Arizona State University research operations. These clients bring:

• RSU income taxable as ordinary income at vest: Arizona taxes at 2.5% in the year of vesting.
• ISO exercises: federal AMT exposure (Arizona has no state AMT, so the AMT calculation is purely federal).
• Nonresident employees: Arizona source income rules apply for income earned in Arizona by nonresidents.
• QBI deduction for founders with pass-through income: flows through from federal AGI to Arizona without a separate adjustment.

Tucson: University and Military

Tucson's tax market has two primary professional niches beyond general individuals. University of Arizona graduate student stipends and fellowships follow federal taxability rules; Arizona follows federal treatment. International students have complex nonresident alien rules at both the federal and state level. Davis-Monthan AFB generates active-duty filers with domicile issues and, increasingly, transition-to-retirement clients benefiting from Arizona's 100% military retirement exclusion.

Agriculture: Pima County, Yuma, Casa Grande

Arizona agriculture (cotton, cattle, lettuce, citrus, hay, dairy) is economically significant in Pima County, Yuma County, and the Casa Grande area. Farm income is reported on Schedule F federally; Arizona follows federal Schedule F treatment. The most significant TY2025 issue for agricultural clients is the OBBBA uncertainty around 100% bonus depreciation and Section 179 for large equipment purchases. An Arizona farmer who federally expensed a $500,000 tractor purchase under OBBBA's restored 100% expensing may face Arizona income on a portion of that amount if conformity is not enacted. Quantify this exposure for your agricultural clients now rather than at amended return time.

Starting a Tax Preparation Business in Arizona

LLC Formation

Arizona LLCs are formed through the Arizona Corporation Commission (ACC).

• Articles of Organization filing fee: $50 (online or paper)
• Annual report: None required. No annual fee.
• Franchise tax: None. Arizona has no franchise tax or gross receipts tax on LLCs.

Arizona requires most newly formed LLCs to publish a notice of formation in an approved newspaper for three consecutive weeks. Exception: LLCs whose registered agent address is in Maricopa County or Pima County are exempt from the publication requirement. For LLCs formed outside those two counties, publication costs approximately $40 to $300 depending on the county.

A single-member Arizona LLC taxed as a disregarded entity pays no entity-level Arizona income tax. Income flows directly to the member's individual return and is taxed at 2.5%. There is no self-employment tax at the state level; SE tax is a federal-only obligation.

No Local Income Tax

Arizona cities and counties do not impose local income taxes or local earned income taxes. All income taxation is at the state level only. This is a meaningful operational simplicity advantage compared to states like Ohio and Pennsylvania, where preparers must track multiple municipal taxing jurisdictions for clients who live, work, or earn income in different cities.
