Arizona Senior Property Valuation Protection: Form 82104

What the Senior Freeze Actually Protects

Arizona homes have more than one value on the assessor’s records. Full Cash Value is linked to market value. Limited Property Value is a separate figure used for property taxes. The State Board of Equalization explains the difference.

Under the current senior program, counties such as Pima and Maricopa describe a three-year freeze of Limited Property Value. Their guidance also warns that tax rates can change. New construction or other property changes can affect the valuation.

Simple example: If your Limited Property Value stays fixed but your local tax rate rises, your bill may still go up. The freeze gives no set dollar discount, refund, or check. It is different from a property-tax exemption and different from a payment deferral. Our property tax relief terms explain those distinctions.

Who May Qualify

The Arizona Constitution Section 18(7), creates the protection. Your county assessor decides whether your application meets its requirements.

• Age: At least one owner must be age 65 or older.
• Ownership: The qualifying person must be an owner of record. A qualifying majority interest in a living trust can count under the constitutional owner definition; ask the assessor for trust paperwork requirements.
• Home: The property must be your primary residence, not a rental or vacation home. Owners generally must have lived there for at least two years before applying.
• Size: The constitutional option includes the residence and up to ten acres of qualifying appurtenant land. County guidance excludes larger or mixed-use properties.
• Income: The three-year average for the owners must be at or below the applicable limit. Tax-free income can count.

If your adult child or another person is on the title, do not leave that name or income off the form. County guidance, including Mohave’s owner instructions, calls for details and signatures from every owner. A spouse or relative living with you is not automatically a titled owner. Ask the assessor whose income is counted in your specific ownership setup.

Mobile homes may qualify when they meet the ownership and primary-residence rules. A person living in an apartment as a tenant should not use this form. For other Arizona tax paths, consult the site’s Arizona property tax guide.

Income Rules: Know Which Year You Are Checking

For the 2026 application cycle, current county guidance gives these limits for the owners’ average annual income over the previous three years:

The published limits appear in the Maricopa County assessor FAQ and Graham County guidance. They are 2026-cycle figures, not confirmed 2027 limits. Limits follow the federal Supplemental Security Income rate. Confirm the new cycle’s figure.

The 2026 county forms ask for income evidence from 2023, 2024, and 2025. They count taxable and nontaxable sources, which can include Social Security, veterans’ disability payments, pensions, wages, investments, and rental or business income. Do not substitute only the taxable income on your federal return. Ask about unusual payments rather than guessing whether they count.

This is an income screen, not a general claim that every asset disqualifies you. Trusts and investment sales can raise separate questions. Ask the assessor.

How to Apply with Form 82104

1. Get the county version. Start with Arizona’s Form 82104 page, then ask your county assessor whether it needs its own revised form or online application. Do not mail the form to the Arizona Department of Revenue.
2. Enter property details. Copy the parcel number and physical address from your assessor record. List the full names and requested details of all owners.
3. Choose initial or renewal. The form covers both. If this is your first request, mark initial. For a continuing freeze, use the renewal route your county gives you.
4. Report the requested income years. Include income from every source and each owner the county must review. Total each year carefully; the assessor verifies the average.
5. Attach proof. Add copies, not irreplaceable originals. Every required person must sign.
6. Submit and keep evidence. Use only the methods the county accepts. Save the full packet and a dated receipt, confirmation email, or mailing record.

County document lists differ. Pima requests returns or year-end statements. Cochise County’s guidance requests proof of age, residency, and three years of all income. Nonfilers can ask about Social Security and other year-end statements.

Never send a Social Security number or full tax return through an unverified email address. Call the assessor through its official site to confirm how sensitive documents should be submitted.

Deadlines: What Happens After September 2026?

The constitutional deadline is September 1. For a timely application, the assessor must give a decision by December 1. Late applications are processed for the following year, but county intake procedures differ.

As of 13 October 2026, the September 1, 2026 deadline is over. Counties may describe application and valuation years differently. Mohave calls its 2026 filing window a request for 2027 values. Maricopa says 2027 applications open after January 1, 2027. Confirm your county’s exact effective year.

If you missed the date, ask: “What is the first valuation year my next accepted application can protect?” Also ask whether the county will accept a late packet now or wants a new application in the next cycle. Do not guess from an old downloadable form. See Maricopa’s next-cycle instructions for one county example.

Renew Every Three Years and Report Changes

Protection runs in three-year periods. To keep it, a qualified owner must reapply every three years. The constitutional renewal rule directs assessors to send a reminder six months before the required reapplication. Keep your own calendar reminder too. A lost letter is not a safe renewal plan.

Before renewing, gather the newest three-year income record and ask if the assessor needs fresh residence or ownership proof. Check that the property details are correct. Tell the assessor about a sale, adding an owner, moving out, renting the home, or major construction before assuming the freeze remains in force.

There is a financial reason to take this seriously. Arizona’s amended A.R.S. 42-13302 provides for a comparable-property recalculation of Limited Property Value when a home leaves this protection in specified situations. The change came through 2025 Senate Bill 1224. Do not assume a return to the old value. Ask for a written explanation before opting out.

If Your Application Is Denied or Delayed

First, read the assessor’s notice. Find out whether it says you missed the deadline, lack a document, exceed the income cap, have an ownership issue, or do not meet the home-use rule. Keep the notice and the date you received it.

1. Ask the assessor for the exact missing item and the way to supply it, if correction is allowed.
2. Ask whether the notice includes a review or appeal process, and request its written deadline. Do not assume a valuation appeal and a senior-program denial use the same procedure.
3. If you think your home’s assessed value is wrong, ask about the separate property valuation appeal route. Pima warns that some valuation petitions can affect senior-freeze enrollment; confirm consequences first.
4. If you must pay a bill now, contact the county treasurer separately. The assessor cannot promise a payment delay just because your application is pending.

Common Mistakes and Reality Checks

• Expecting a fixed bill: Tax rates and property changes can still affect what you owe.
• Using net taxable income only: Counties include nontaxable sources and use a three-year average.
• Leaving out a co-owner: Ownership affects the income test, signatures, and proof needed.
• Reusing old limits: The published 2026 figures do not establish the 2027 thresholds.
• Forgetting renewal: Reapplication is required every three years; removal may lead to recalculation.
• Calling the wrong office: The assessor handles the protection application; the treasurer handles the bill.

If other bills are a problem, the Arizona senior assistance guide lists other Arizona programs, not property-tax discounts.
