Arizona Property Tax Guide: Pay, Search, Due Dates & Exemptions
Arizona property tax is handled mostly at the county level. Your county assessor manages valuation, classification, exemptions and many correction issues. Your county treasurer handles tax bills, payments, receipts, delinquent taxes and most payment records.
This guide explains how to search an Arizona parcel, pay the treasurer, understand October and March due dates, read the notice of valuation, review exemptions, check senior relief options, and appeal a value or classification before the deadline.
Quick Answer
To look up or pay Arizona property tax, start with the county where the property is located. Use the county assessor for parcel records, ownership, valuation, classification and exemption questions. Use the county treasurer for tax bills, payment history, receipts, delinquent balances and tax lien questions.
Arizona property taxes are usually split into two installments. The first half is due October 1 and becomes delinquent after November 1 at 5:00 PM. The second half is due March 1 and becomes delinquent after May 1 at 5:00 PM.

Arizona Property Tax Offices: Assessor vs Treasurer vs ADOR
Arizona property tax is not handled by one single statewide payment portal. The Arizona Department of Revenue provides statewide property tax guidance, forms and oversight, but county offices handle most parcel-level work.
For most homeowners, the assessor and treasurer are the two offices that matter. The assessor values and classifies the property. The treasurer bills and collects the tax after values and tax rates are applied.
| Office | Main Job | Use This Office For | Do Not Use It For |
|---|---|---|---|
| County assessor | Valuation, classification, parcel records and many exemptions. | Notice of valuation, owner record, property class, appeal, senior freeze and exemption questions. | Final payment receipt or delinquent tax payoff. |
| County treasurer | Tax bills, payment collection, receipts and delinquency records. | Paying tax, checking paid status, duplicate bill, escrow payment and tax lien questions. | Changing value, class or parcel characteristics. |
| Arizona Department of Revenue | State property tax guidance, forms and oversight. | State forms, property tax publications, credits and statewide guidance. | County parcel balance or county payment receipt. |
| State Board of Equalization | Certain valuation and classification appeals after assessor-level review. | Appeal route after county assessor decision when eligible. | Paying the tax bill. |
- Confirm the property county.
- Open the county assessor for value and parcel records.
- Open the county treasurer for tax bill and payment records.
- Use ADOR forms only when the county or state instructions require them.
How to Search Arizona Property Tax Records
Most Arizona counties provide online tools to search property records. The assessor search usually shows parcel data, owner information, legal description, values and classification. The treasurer search usually shows tax bills, installments, payment history and balances.
Start with the parcel number if you have it. Address search can work, but formatting may differ by county. Owner-name search can be useful, but it may be delayed if there was a recent sale, trust transfer, estate change or mailing-address correction.
If you cannot find the property: try the parcel number without dashes, remove apartment/unit formatting, search only the street number and street name, or contact the assessor for help.
How to Pay Arizona Property Tax
Arizona county treasurers collect property taxes. Payment options may include online card or e-check, mail, drop box, in-person counter, phone payment, escrow payment by a mortgage servicer, or other county-specific methods.
Before paying, verify the county, parcel number, tax year, installment, owner name and amount. A payment to the wrong parcel or wrong year can delay receipts and may not stop interest on the correct account.
| Payment Route | Best For | Check Before Paying |
|---|---|---|
| County treasurer online portal | Quick payment, printable receipt and balance lookup. | Parcel, year, installment, service fee and posting time. |
| Mail payment | Taxpayers with a paper bill and no urgent receipt need. | Correct mailing address, coupon, check memo and postmark instructions. |
| In person or drop box | Urgent receipt, old bill, delinquent balance or complicated account. | Office hours, accepted payment methods and proof of identity if needed. |
| Mortgage escrow | Owners whose lender collects tax monthly. | Treasurer paid status and lender escrow disbursement confirmation. |
- Open the official county treasurer website.
- Search by parcel number if possible.
- Confirm the tax year and installment.
- Review convenience fees and payment cutoff times.
- Save the confirmation and print the official receipt after posting.
Arizona Property Tax Due Dates and Delinquent Dates
Arizona property taxes are usually payable in two halves. The first half is due October 1 and becomes delinquent after November 1 at 5:00 PM. The second half is due March 1 and becomes delinquent after May 1 at 5:00 PM.
If the total tax is $100 or less, the full amount is due October 1 and becomes delinquent after December 31 at 5:00 PM. Some county pages also note that if a delinquency date falls on a weekend or legal holiday, the delinquency time may move to the next business day.
| Date | What It Means | What to Do |
|---|---|---|
| October 1 | First half of property taxes is due. | Pay first half or confirm escrow payment plan. |
| After November 1 at 5:00 PM | First half becomes delinquent if unpaid. | Pay before cutoff or verify full-year payment option with county treasurer. |
| December 31 at 5:00 PM | Taxes of $100 or less become delinquent if unpaid. | Pay small bills in full before this cutoff. |
| March 1 | Second half of property taxes is due. | Pay the second installment or verify escrow has paid. |
| After May 1 at 5:00 PM | Second half becomes delinquent if unpaid. | Pay before cutoff to avoid delinquent interest and collection problems. |
- Open your county treasurer tax bill page.
- Check whether the bill is split into two halves or under the $100 rule.
- Review county posting and postmark rules.
- Save proof if your mortgage company pays from escrow.
Arizona Notice of Valuation: What It Shows
County assessors mail a Notice of Valuation to the owner of record. For real property, the notice is mailed before March 1. The notice usually includes Full Cash Value, Limited Property Value and the property classification.
This notice is not the same as the fall tax bill. It is your early warning to check the value and classification. If the Full Cash Value is too high or the property class is wrong, the appeal deadline starts from the notice mailing date.
| Notice Item | Plain Meaning | What to Check |
|---|---|---|
| Full Cash Value | Often used as the assessor’s market-value-related number. | Compare with sales, property condition and similar parcels. |
| Limited Property Value | A value used in Arizona’s property tax system for primary tax calculations. | Compare with prior year, class and assessor notes. |
| Property classification | The legal class assigned to the property. | Make sure owner-occupied residential, rental, commercial, vacant land or other class is correct. |
| Parcel characteristics | Land, improvement, size, use, year built and other property details. | Look for wrong square footage, use, acreage, pool, garage or structure details. |
| Mailing date | The date that starts the appeal timeline. | Count the appeal deadline from the official mailing date. |
How Arizona Property Tax Is Calculated
Arizona property tax is based on property value, classification, assessment rules and local tax rates. Local rates can include county, city, school, community college and special district levies.
The exact county formula can be confusing because Arizona uses Full Cash Value, Limited Property Value, property class and different tax rates. For user purposes, the practical workflow is simple: check the assessor value and class first, then check the treasurer bill and tax rates.
| Part of Bill | Who Controls It | Why It Can Change |
|---|---|---|
| Value | County assessor | Market changes, property improvements, new construction, split/combination or correction. |
| Classification | County assessor | Owner occupancy, rental use, commercial use, vacant land or other use changes. |
| Tax rates | Taxing jurisdictions | Budgets, school districts, bonds, overrides and special district levies. |
| Bill and payment | County treasurer | Installments, prior delinquency, interest, fees, tax lien activity or escrow timing. |
Simple rule: If the property facts, value or class are wrong, contact the assessor. If the amount due, receipt or delinquency status is wrong, contact the treasurer.
Arizona Property Tax Exemptions and Relief Programs
Arizona property tax relief depends on your property, income, age, disability, status and county records. Some programs reduce taxable value, some freeze valuation, and some are claimed as an income tax credit.
Do not assume you qualify automatically. Most relief programs require an application, affidavit, form, deadline or annual/renewal verification through the county assessor or Arizona Department of Revenue.
| Program or Relief | Who It May Help | Where to Start |
|---|---|---|
| Senior Property Valuation Protection Option | Qualified seniors by age, income and primary residence rules. | County assessor / ADOR Form 82104. |
| Widow, widower or disability exemption | Eligible Arizona residents meeting statutory conditions and limits. | County assessor affidavit and required documents. |
| Disabled veteran-related exemption | Certain veterans with qualifying disability status, subject to current law and county review. | County assessor and current ADOR/county instructions. |
| Property Tax Refund Credit | Qualified individuals who paid property tax or rent on Arizona property. | ADOR Form 140PTC. |
| Owner-occupied residential classification | Homeowners whose primary residence class is wrong. | County assessor classification correction. |
- Check the property classification on the assessor record.
- Ask the county assessor which exemptions or valuation protection options may apply.
- Use current-year forms, because income and eligibility rules can change.
- Keep proof of age, disability, residency, ownership, income and occupancy.
- Do not miss county filing deadlines.
How to Appeal Arizona Property Value or Classification
If you believe the Full Cash Value is greater than market value or the property classification is wrong, you can file a Petition for Review with the county assessor. For real property, the appeal is generally due within 60 calendar days of the Notice of Valuation mailing date.
Personal property appeals have a shorter timeline. Arizona Department of Revenue guidance states that real property appeals must be filed within 60 days and personal property appeals within 30 days.
- Find the notice mailing date.
- Confirm whether the issue is value, classification or factual property error.
- Gather evidence before filing: sales, appraisal, photos, repair estimates, income data if relevant, or property-detail correction proof.
- Use the county assessor Petition for Review route.
- Save filing confirmation and watch for assessor response deadlines.
| Evidence Type | Best For | How to Use It |
|---|---|---|
| Recent comparable sales | Full Cash Value dispute. | Use similar location, size, age, condition and sale date. |
| Purchase closing statement | Recent buyer with value above purchase evidence. | Show arm’s-length sale price and date. |
| Photos and repair estimates | Condition, damage or deferred maintenance. | Label photos and connect repairs to value impact. |
| Property characteristic correction | Wrong square footage, land size, class, use or improvement detail. | Mark the incorrect assessor record and attach proof. |
| Rental or commercial income records | Income-producing property. | Use clear operating data and explain the valuation relevance. |
New Arizona Property Owner Checklist
New owners often assume the county record, mailing address, mortgage escrow and tax bill will update automatically. That can cause missed notices, wrong addresses and late payment problems.
- Search the county assessor record after closing.
- Confirm owner name, mailing address, situs address and parcel number.
- Check the county treasurer page for open tax balances.
- Ask your lender whether taxes are escrowed and when payment will be sent.
- Watch for the valuation notice before March 1 and the tax bill later in the year.
- Review classification and exemption options with the assessor.
Escrow warning: Even if your mortgage company is supposed to pay, you should still verify the county treasurer shows payment posted before delinquency.
Late Payments, Interest and Tax Lien Risk
If Arizona property tax is not paid by the delinquency cutoff, interest and collection issues can begin. County treasurer pages may show interest, fees, prior-year taxes, lien information or tax sale records.
Do not ignore an old balance just because the current year looks paid. A prior-year delinquency can affect payoff, title transfer, refinancing, tax lien sale status or escrow review.
| Problem | Start Here | What to Ask |
|---|---|---|
| Payment posted late | County treasurer | Posting date, interest, receipt and payment source. |
| Mortgage escrow did not pay | Treasurer plus lender | County balance, lender disbursement date and escrow shortage. |
| Prior-year tax due | County treasurer | Full payoff amount through a specific date. |
| Tax lien notice | County treasurer | Lien status, redemption amount, deadlines and receipt rules. |
| Wrong owner or mailing address | Assessor and treasurer | Which office updates the record and whether past bills were mailed. |
Do not wait: Delinquent tax issues can become more expensive and harder to fix. Contact the county treasurer for the current payoff instead of estimating interest yourself.
Refunds, Duplicate Payments and Form 140PTC
If you paid the wrong parcel, paid twice, or paid after a mortgage company already paid, contact the county treasurer. Treasurer offices handle account-level payment records and refund routing.
Do not confuse a county payment refund with Arizona Form 140PTC. Form 140PTC is an Arizona property tax refund credit claim used by qualified individuals for taxes paid on Arizona property owned or rented by the taxpayer.
| Issue | Correct Route | Documents to Keep |
|---|---|---|
| Duplicate county payment | County treasurer | Receipts, parcel number, check/card details and payment dates. |
| Wrong parcel paid | County treasurer | Confirmation number, payer name, intended parcel and paid parcel. |
| Escrow overpayment | County treasurer and mortgage servicer | Escrow statement, county receipt and lender disbursement record. |
| Property tax refund credit | Arizona Department of Revenue Form 140PTC | Tax/rent records, income information and ADOR instructions. |
Arizona Personal Property and Business Property Tax
Arizona property tax can also involve personal property, especially business personal property. This may include taxable equipment, machinery, furniture, leased property or other business assets depending on the county and property type.
Personal property valuation notices can have different timing and appeal rules than real property. ADOR guidance states that personal property appeals generally must be filed within 30 days.
Keep purchase records, asset lists, depreciation schedules, lease documents and disposal proof.
Check value, class, account number, owner name and business location.
Personal property appeals can move faster than real property appeals, so review notices immediately.
Use the county treasurer for payment after the account is billed.
Common Arizona Property Tax Mistakes
Most problems come from mixing up offices, missing appeal deadlines, assuming escrow paid, or waiting until a tax lien notice arrives.
The treasurer cannot reduce value or change property classification. Start with the assessor.
The valuation appeal deadline is tied to the notice, not the later tax bill.
Full Cash Value is important, but Limited Property Value and class can also affect the bill.
Check the treasurer record before November and May delinquency cutoffs.
Match parcel number, tax year, installment and owner name before submitting payment.
Relief programs usually require forms, documentation and deadlines.
Documents to Keep
Good records help with valuation appeals, exemptions, refunds, escrow questions and future sales.
| Situation | Documents to Keep | Why It Helps |
|---|---|---|
| Property search | Parcel number, legal description, owner name and mailing address. | Helps match assessor and treasurer records. |
| Tax payment | Bill, receipt, confirmation number, check/card record and postmark proof. | Supports paid status and refund claims. |
| Value appeal | Notice, comparable sales, appraisal, photos, repair estimates and property records. | Shows why value or class should change. |
| Exemption or senior freeze | Age, income, disability, residency, ownership and occupancy proof. | Supports eligibility review. |
| Mortgage escrow | Escrow statement, lender confirmation and county receipt. | Shows whether the lender paid on time. |
