6 Documents Arizonans Need for the Senior Property Valuation Freeze

Nothing slows down an application like a missing piece of paper.

Arizona counties don’t all ask for exactly the same documents, so it helps to know what yours wants.

Here’s what to gather for the senior property valuation freeze, with examples from several counties.

Note: This is general information, not legal or tax advice. Assessment rules, income limits, paperwork requirements, and deadlines are subject to change, so confirm the current details with your county assessor.

1. Your Signed Application

The Arizona Department of Revenue publishes the senior freeze application as Form 82104.

Maricopa County’s assessor asks for a completed and signed 2026 application, so use the version your county’s page names.

Mohave County’s assessor says each owner of the property title must be listed, with a name and date of birth, and must sign.

If you share the title with a spouse, that means both of you.

Form 82104 has you certify under penalty of perjury that your answers are true.

Read it before you sign.

2. Proof You’re 65

You can prove your age for the senior freeze with a birth certificate, a driver’s license or a passport, according to Cochise County’s assessor.

Maricopa County’s assessor asks for proof that at least one household member is 65 or older.

Pima County’s 2025 form requires at least one owner to be 65 by September 1 and says to send copies, never originals.

3. Proof of Residency

Residency proof for the senior freeze can be an Arizona driver’s license, a state ID or a voter registration card, according to Mohave County’s assessor.

A primary residence is the home you occupy for nine months of the calendar year.

Pinal County asks you to bring your Arizona driver’s license.

If it’s under two years old, bring a voter registration card, a utility statement or a vehicle registration too.

Cochise County wants a record that shows your physical address for the two years before you apply.

Check that the address on each paper matches the home you’re freezing.

Mohave County’s assessor also requires two years in the home before you apply, so if you moved within the last two years, call your assessor before you file.

4. Three Years of Tax Returns

For the senior freeze, Mohave County's assessor asks for copies of pages 1 and 2 of your federal tax return for each year it lists.

Its 2026 window listed 2023, 2024 and 2025.

Maricopa County's assessor lists the first two pages of your Form 1040 for the last three years, from all property owners.

Each window asks for a new set of years, so pull the years your county's current page names.

5. Social Security and 1099 Statements

Maricopa County's assessor lists Social Security and 1099 statements for senior freeze applicants who didn't file federal returns.

Those are your Social Security statement and any 1099 forms for the last three years.

The county's 2026 form also lists veterans' benefit statements.

Pinal County's page names Social Security benefits, retirement and pension income, annuities and wages among the income types on its list.

If you're retired, Cochise County's assessor asks for all other sources of income, so any pension or retirement statements belong in your stack.

6. Trust Paperwork

In Pinal County, the senior freeze application needs proof of the trustees when a trust holds the home.

If you're unsure whether your county wants trust papers, ask your assessor before you file.

Income Limits

The senior freeze caps the combined income of every owner on the title.

The returns and statements above exist to prove you're under that cap.

The 2026 limit is $47,712 for one owner and $59,640 for two or more.

Yavapai County's page listed limits of $46,416 for one owner and $58,020 for two or more on applications filed in 2025.

Limits change from year to year, so use the figures on your county's page for the year you file.

Mohave County's assessor counts income from all sources, taxable and non-taxable.

Maricopa County's assessor says that includes Social Security and veterans' disability payments.

Cochise and Maricopa counties average your income over three years instead of judging a single year.

Renewal Paperwork

The senior freeze holds your Limited Property Value for three consecutive years, according to Maricopa County's assessor, and then you have to renew.

Mohave County's assessor says you have to renew the option in 2-1/2 years.

Form 82104 says to renew during the last six months of the three-year period, after you receive a notice of reapplication.

Pinal County's assessor notifies owners six months before the current period expires.

Keep a copy of everything you file now, so you know what you sent the first time.

Cochise County's assessor says the freeze holds your property valuation but not your tax bill, so keep the freeze in mind when you budget for aging in place.

When and How to File

You file the senior freeze application with the assessor in the county where your primary residence is located.

Mohave County's window for freezing 2027 values ran from January 5 through September 1, 2026.

Cochise, Maricopa and Mohave counties all name September 1 as the deadline.

Yavapai County's 2025 deadline was September 2, so read your county's date instead of assuming.

Pinal County's assessor takes applications in person only and won't accept them by mail.

Yavapai County's 2025 page says applications can be submitted in person, by mail or by email.

Send every supporting document with the application, including proof of age, residency and income verification for the past three years.

Senior Property Valuation Freeze Documents by County

The senior property valuation freeze documents you gather depend on your county, and each assessor's list reads a little differently.

Mohave County's list has tax return pages, and Maricopa County's has Social Security and 1099 statements for applicants who didn't file returns.

Check your county's list before you copy anything.
