Arizona Individual Income Tax 2026: Flat 2.5% Rate, Form 140, Due Date and Extensions
Arizona individual income tax uses a flat 2.5% tax rate for tax year 2023 and beyond. For tax year 2025, the individual filing due date is April 15, 2026. If you need more time to file, Arizona Form 204 can provide an automatic extension to file until October 15, 2026, but it is not an extension to pay tax due.
| Individual tax item | What to know | Action |
|---|---|---|
| Form 140 | Arizona resident individual income tax return. | Use the correct current-year form and instructions. |
| Flat tax rate | Arizona taxable income uses a 2.5% flat rate for tax year 2023 and beyond. | Do not use old optional or X/Y tax tables. |

| Extension | Arizona Form 204 must be filed by April 15, 2026, for an automatic extension to file until October 15, 2026. | Pay any tax due by April 15 to reduce penalties and interest. |

| Withholding | Arizona withholding should align with the 2.5% flat tax environment for tax year 2023 and beyond. | Review your Arizona Form A-4 and employer withholding. |
Arizona DOR Refund Status: Where’s My Refund, Processing Time and What to Prepare
Arizona refund status can be checked online through ADOR’s “Where’s My Refund?” page or AZTaxes refund tools. Refund information can also be obtained through the automated phone system by calling 602-255-3381 and choosing the refund option after language selection.
Before checking refund status
- Prepare the Social Security number used on the return.
- Prepare the ZIP code from the return.
- Prepare the filing status reported on the return.
- Prepare the tax year you are checking.
- Know whether the return was e-filed or paper filed.
- Check whether ADOR sent an identity, review or document request letter.
When to call about a refund
ADOR tells paper filers to allow time before contacting Customer Care about a return. Refunds requiring review or investigation may take longer than standard processing. Use the online tool first because phone support may not have more information than the official status system.
Arizona Transaction Privilege Tax: TPT License, AZTaxes Filing, Rates and Due Dates
Arizona Transaction Privilege Tax is commonly called “sales tax,” but ADOR explains that TPT is actually a tax on a vendor for the privilege of doing business in Arizona. Various business activities are subject to TPT and may require licensing.
| TPT topic | What to know | Best action |
|---|---|---|
| TPT license | Businesses engaged in taxable activities may need an Arizona TPT license. | Apply or manage the license through AZTaxes. |
| State, county and city rates | TPT rates vary by business code, region code and city code. ADOR updates rate tables monthly. | Use the current official TPT rate table for the transaction period. |
| Monthly return deadline | Monthly TPT return deadline is generally the 20th after the activity month. | Check the official due date calendar for paper and electronic deadlines. |
| Electronic deadline | ADOR’s calendar lists AZTaxes electronic return/payment deadlines, often near the end of the month, before 11:59 p.m. on the listed date. | Do not wait until the last minute. |
| Electronic filing threshold | TPT filers with annual total tax liability of $500 or more are required to file electronically. | Use AZTaxes and keep confirmation records. |
| TPT license renewal | ADOR notes 2026 TPT license renewals were due January 1, with penalties assessed for renewals received after January 31. | Renew on time and verify business location details. |
Arizona Business Tax Registration: AZTaxes, TPT License, Withholding and Local Codes
Arizona businesses may need ADOR accounts for Transaction Privilege Tax, withholding, corporate income tax, use tax, luxury tax, licensing and other tax activities. AZTaxes is the main portal for many registration, filing and payment actions.
Businesses should check ADOR registration when they
- Sell taxable products or services in Arizona.
- Need a Transaction Privilege Tax license.
- Have employees and Arizona withholding obligations.
- Open or close a taxable business location.
- Sell in multiple Arizona cities or counties.
- Receive ADOR notices or need to file/pay business tax.
Prepare before opening AZTaxes
- FEIN, SSN/ITIN or Arizona account number.
- Legal business name and trade name.
- Entity information from Arizona Corporation Commission if applicable.
- Business location, city and region code details.
- Start date of Arizona taxable activity.
- Tax types needed: TPT, withholding, corporate or other.
Arizona Business Owner Workflow: Corporation Commission → IRS → ADOR → City/County License
Arizona DOR is not the same as the Arizona Corporation Commission, IRS, city business license office or county property office. Use this workflow before launching, hiring, selling taxable items or renewing a license.
| Step | Where to go | Why it matters | Common mistake |
|---|---|---|---|
| 1. Business entity | Arizona Corporation Commission | Forms or searches LLCs and corporations. | Thinking ADOR creates your LLC. |
| 2. Federal EIN | IRS | Needed for payroll, banking and many tax registrations. | Paying unnecessary third-party EIN fees. |
| 3. State tax accounts | Arizona DOR / AZTaxes | Registers TPT, withholding and business tax accounts. | Selling taxable items before licensing. |
| 4. City/county licenses | City or county offices | Local business license, zoning, permit or regulatory rules may apply. | Assuming a TPT license replaces local business license rules. |
| 5. Industry rules | Relevant state or local agency | Contracting, lodging, restaurant, alcohol, tobacco and regulated industries may require extra approvals. | Only setting up AZTaxes and ignoring industry requirements. |
Arizona Withholding Tax: Employer Filing, Form A-4 and Payroll Records
Arizona withholding tax applies when employers withhold Arizona income tax from wages. Withholding should be reviewed in light of the 2.5% flat individual income tax rate for tax year 2023 and beyond. Employees use Arizona Form A-4 to elect withholding percentage.
Employer checklist
- Register for Arizona withholding when required.
- Collect and maintain Arizona Form A-4 from employees.
- Deposit and file withholding according to assigned ADOR frequency.
- Keep payroll, W-2 and 1099 records.
- Use AZTaxes or official ADOR tools for payments where available.
Employee withholding tip
If refund or balance due results are unexpected, employees should review Arizona Form A-4 and federal withholding together. Arizona withholding is separate from federal IRS withholding.
Arizona Corporate Income Tax: Business Filing, Extensions and Estimated Payments
Corporations with Arizona income, Arizona activity or Arizona filing obligations should review ADOR corporate income tax forms and instructions. Corporate filing is separate from Arizona Corporation Commission entity records and separate from TPT licensing.
Businesses that should check corporate tax
- C corporations doing business in Arizona.
- Corporations with Arizona-source income.
- Entities registered with the Arizona Corporation Commission but unsure about tax filing.
- Businesses making Arizona estimated income tax payments.
- Tax professionals filing corporate returns or extensions.
Do not confuse three systems
Arizona Corporation Commission records, ADOR corporate income tax filing and AZTaxes TPT licensing are different tasks. A business may need more than one depending on legal structure and activity.
Arizona Property Tax: Why ADOR Is Not Usually Where You Pay Your Bill
Arizona property tax bills, assessments, valuation notices and exemptions usually involve county offices. ADOR provides state-level information and certain property tax guidance, but most owner-facing payment and assessment questions start with your county assessor or county treasurer.
| Property tax issue | Usually correct office | Why |
|---|---|---|
| Property tax bill or payment | County treasurer | County treasurers collect property tax bills. |
| Assessed value or valuation notice | County assessor | Assessment and valuation questions start locally. |
| Exemption or classification | County assessor | Eligibility and local records are county-based. |
| Appeal or dispute | County process / tax court path when applicable | Deadlines and documents depend on local notice type. |
| State property tax information | Arizona DOR property tax pages | ADOR provides statewide forms, education and guidance. |
Arizona Rental Tax: Residential Rental, Short-Term Rental and TPT Confusion
Arizona rental tax rules can be confusing because long-term residential rental, short-term lodging, city TPT and platform collection are not always the same. ADOR notes that starting January 1, 2025, residential rental property owners should no longer collect and remit city TPT on income from long-term lodging stays of 30 or more consecutive days.
Rental owners should verify
- Whether the stay is 30 or more consecutive days.
- Whether the activity is short-term lodging or long-term residential rental.
- Whether city, county or state TPT applies to the transaction type.
- Whether a platform collected the correct taxes.
- Whether local license, permit or zoning rules apply.
Platform collection warning
Airbnb, Vrbo and other platforms may collect some taxes in some situations, but owners should not assume every state, county, city and local obligation is covered for every transaction. Keep gross receipts, platform reports, exemption records and license details.
Arizona DOR Notice, Audit, Lien or Collection Issue: What To Do Next
An ADOR notice can involve refund verification, missing returns, account mismatch, TPT license renewal, TPT liability, income tax balance, withholding, audit, bankruptcy, lien, collection, offer-in-compromise or other tax account issues. Do not ignore it, but verify the contact through official ADOR channels.
| Notice type | First thing to check | Best action |
|---|---|---|
| Refund or identity notice | Tax year, SSN, filing status and requested verification method. | Use official ADOR or AZTaxes tools; avoid suspicious links. |
| Missing return notice | Tax type, period and filing confirmation records. | Compare with your submitted return and respond with proof if needed. |
| TPT notice | License number, location, activity month, city/region code and amount. | Prepare AZTaxes records and rate table support. |
| Withholding notice | Deposit period, payroll records and payment confirmations. | Compare payroll records before calling. |
| Audit contact | Callback number, tax type, period and requested documents. | Verify using ADOR’s listed callback numbers. |
| Lien or collection issue | Amount, tax year, account ID and deadline. | Contact ADOR promptly through official contact paths. |
Arizona Local Tips: Phoenix, Mesa, Tucson, City TPT and County Offices
Arizona tax searches often involve multiple government offices. ADOR handles state tax administration and centralized TPT tools, but entity formation, county property tax, local permits and some city rules may belong somewhere else.
Phoenix business tip
Phoenix-area businesses should check TPT business codes, city codes, Maricopa County issues and local licensing. A TPT license does not automatically solve every city permit or zoning requirement.
Mesa office tip
The Mesa office has different public hours than the Phoenix office and is listed as closed on Fridays. Check the official locations page before visiting.
Tucson and Pima County tip
For Tucson-area property tax bills, values or exemptions, start with Pima County offices. Use ADOR for state income tax, TPT and official tax account questions.
Short-term rental tip
Short-term lodging may involve TPT and local rules. Platform collection may not cover every obligation, especially when ownership, location or business activity changes.
Business entity tip
Arizona Corporation Commission handles many LLC and corporation records. ADOR handles tax accounts. Many businesses need both plus an IRS EIN.
Call-before-visiting tip
ADOR says it aims to reduce the need to travel or wait in line. Before visiting, check the office page and bring notices, returns, payment confirmations, IDs and license details.
Arizona DOR Offices: Phoenix, Mesa and Tucson Service Strategy
