How to Appeal Property Taxes in Pima County, Arizona (2026 Guide)

The 2027 Pima County residential Notice of Value was mailed Friday, February 13, 2026, so the normal Assessor-level appeal deadline was Tuesday, April 14, 2026. If you missed that county petition deadline and did not already start the administrative appeal, the remaining 2026 route for the same valuation notice is a direct Arizona Tax Court appeal by December 15, 2026.

To file at the Assessor level in the normal window, use Arizona DOR Form 82130R, “Residential Petition for Review of Valuation,” and submit it to the Pima County Assessor at ASRpc@pima.gov or 240 N. Stone Ave., Tucson, AZ 85701-1200. There is no fee for the administrative appeal; court filing is separate and can involve filing fees.

How assessments work in Pima County

Pima County does not reassess homes only when they sell. The Assessor annually discovers, lists, classifies and values real property, then mails a Notice of Value by March 1 for the following tax year. In 2026, homeowners received the Tax Year 2027 value notice; that value is for taxes first payable in fall 2027.

Your notice has two numbers that matter: Full Cash Value (FCV) and Limited Property Value (LPV). FCV is the Assessor’s market-value estimate. LPV is the value used to calculate taxes for most real property, and for existing property it generally can rise only 5% per year unless there is a significant change such as new construction, parcel split/combination or a change in use. For a typical owner-occupied home, the classification is Class 3 and the assessment ratio is 10%, so a $350,000 LPV becomes a $35,000 limited assessed value before tax rates are applied.

For residential property, Pima says it uses the market approach, analyzing the previous 36 months of sales for properties similar in size, age, quality, location and other characteristics. That means the best appeal evidence is usually not “my taxes are too high”; it is proof that the Assessor’s value or classification is wrong.

One Pima-specific trap: lowering FCV does not always lower the next bill. If your LPV is already far below FCV, a modest FCV reduction may not change taxable value. Before filing, compare the FCV, LPV, property class and listed home characteristics on your parcel record.

Whether you should appeal

Appeal if you can show one of these with evidence: the FCV is above market, the property record is wrong, your home is misclassified, or the LPV calculation is incorrect. Start by searching your parcel on the Pima County Assessor site and checking living area, lot size, year built, pool, outbuildings, quality, condition and legal class.

Good evidence for Pima homes includes three to five comparable sales near your valuation date; photos and contractor estimates for serious condition problems; a recent appraisal; or documents showing primary-residence classification. Form 82130R specifically asks for your opinion of value and the method you are using, such as market sales approach or cost approach.

Pima publishes appeal volume, but not a clean homeowner “success rate” or median reduction. In its 2025 annual report, the Assessor reported 1,391 total appeals, 841 resolved at the Assessor level, 804 total State Board of Equalization hearings, 347 withdrawals by agents at SBOE, and 402 valuation changes approved by SBOE. Treat that as useful workload context, not a promise that your case will be reduced.

Step-by-step how to file

1. Confirm the deadline on your notice. For the 2026 mailing cycle, the 2027 Real Property Notices of Value were mailed February 13, 2026. The Assessor’s stated deadline to petition was April 14, 2026. The general rule is 60 days after the Notice of Value mail date or the deadline printed on the notice.

2. Download the right form. Homeowners use Residential Petition for Review of Valuation, DOR Form 82130R. If an agent represents you, attach Agency Authorization, DOR Form 82130AA. If multiple parcels are one economic unit, check whether Multiple Parcel Appeal Form, DOR Form 82131 is needed. Commercial and other real property generally use DOR Form 82130, not the residential form.

3. Fill in the tax year and parcel number exactly. The current Pima residential form is marked for Tax Year 2027. Include the value on the notice, your requested FCV and LPV/class if applicable, and your basis for appeal. Sign it; unsigned petitions can be rejected.

4. Attach evidence, not arguments alone. Put the parcel number on supporting documents. For comparable sales, include address, parcel if possible, sale date, sale price, size, age and why the sale is comparable. If the issue is classification as a primary residence, attach proof such as Arizona driver license, voter registration, tax-return address page, utility bill or vehicle registration.

5. Submit to Pima County Assessor. The official residential form lists email submission to ASRpc@pima.gov and mail to 240 N. Stone Ave., Tucson, Arizona 85701-1200. You may also hand-deliver to the Assessor’s office at 240 N. Stone Ave. I found email, mail and hand-delivery instructions for the initial Assessor petition; I did not find a separate Pima Assessor appeal portal for Form 82130R. For later SBOE appeals, the State Board offers online filing plus mail/hand-delivery requirements.

6. Keep proof. Save your sent email, attachments and timestamp. If mailing, use a trackable service; the U.S. Postal Service postmark is evidence of timely filing.

What happens after

The first review is not a courtroom hearing. The Assessor assigns an appraiser to review the petition and may schedule an inspection. On Form 82130R you can check the box requesting a meeting with Assessor staff. If you cannot attend, submit written evidence before the meeting date. The Assessor must rule on all regular Notice of Value petitions by August 15.

If the Assessor grants exactly what you requested, you generally cannot appeal further. If you disagree with the Assessor’s decision, Pima County homeowners go to the Arizona State Board of Equalization, not a local county board. In Maricopa and Pima counties, the Board of Equalization function is handled by SBOE members and appointees.

The SBOE deadline is 25 calendar days after the Assessor’s decision is mailed. You may also bypass SBOE and go to Tax Court within 60 days after the Assessor’s decision. If you never filed the Assessor petition, you may file directly in Tax Court by December 15 of the valuation year — for the 2027 notice mailed in 2026, that date is December 15, 2026.

SBOE hearings for Pima property are held in person in Pima County, typically at the State Office Building North, 400 W. Congress, Tucson, with the exact room on the mailed hearing notice. SBOE says hearing notices are mailed at least 14 days before the hearing, evidence from earlier levels is not automatically forwarded, and for Class 3 homes under $3 million FCV it recommends bringing an original plus two copies. SBOE must complete regular valuation hearings and issue decisions by October 15. There is no true “paper only” safe option: if you do not appear, the panel may or may not review your evidence.

Local tips

Look at LPV before estimating savings. Suppose a Tucson homeowner reduces LPV from $350,000 to $330,000. Class 3 residential assessment is 10%, so taxable assessed value drops by $2,000. Using Pima County’s adopted FY 2026 county-related total rate of $5.1961 per $100 of net assessed value, the county-portion savings would be about $103.92: $2,000 ÷ 100 × 5.1961. A full tax bill includes school, city/town and special district rates. In one official 2025 Tucson tax area example, combined primary and secondary rates were 13.9274 per $100, which would make the same reduction about $278.55 before any primary tax reduction. Your exact rate depends on your tax area code.

Use the Assessor’s own model facts. Because Pima values homes by comparing sales and characteristics, wrong square footage, a listed pool you do not have, or a condition issue not visible from the street can be more persuasive than broad claims about the market.

Check relief programs separately from appeals. Arizona has no general “homestead exemption” that automatically cuts every owner-occupied home’s assessed value. But Pima administers valuation relief for disabled veterans, widows/widowers, disabled persons and nonprofits, generally requiring filing between the first Monday in January and March 1 unless a waiver applies. The Senior Property Valuation Protection option can freeze limited value in three-year increments for qualified seniors age 65+, with a September 1 application deadline; it does not freeze the tax rate or the tax bill.

Do not appeal just because the tax bill rose. The Assessor cannot change tax rates. Pima tax rates are adopted annually by the Board of Supervisors and other taxing jurisdictions, and tax bills are issued by the Treasurer. Your appeal is about value, classification or an objective property-tax error.
