La Paz County Property Tax Appeal, Arizona

On the typical La Paz County home, valued near $100,000 at the county’s effective tax rate of 0.83%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.
2026 Appeal Deadline: 60 days from the date the Notice of Value was mailed (typically mailed by March 1, making the deadline approximately late April or early May 2026)
The appeal deadline is calculated as 60 calendar days from the mailing date of your Notice of Value, which is printed on the notice itself. Assessment notices are typically mailed in February by the county assessor. Property owners must file within this 60-day window to preserve their appeal rights for the administrative process.

How La Paz County Assesses Property
Assessed by: La Paz County Assessor's Office
Assessment cycle: annual
Notices typically mailed: February (by March 1)
In Arizona, owner-occupied residential properties are assessed at 10% of their full cash value (market value). For example, if your home's market value is $100,000, at Arizona's 10% assessment ratio your assessed value would be $10,000, resulting in approximately $830 in annual taxes at La Paz County's effective rate of 0.83%. This assessment ratio is set by state law and applies uniformly across all Arizona counties for primary residences.
The Appeal Process
Appeals are heard by the La Paz County Board of Equalization / Arizona Tax Court. At the informal level, the assessor reviews your evidence and may adjust the value without a formal hearing. If you proceed to the County Board of Equalization, expect a quasi-judicial hearing where you present evidence and the Board makes a decision based on the record. Tax Court appeals are formal judicial proceedings.
Step 1: Review your Notice of Value when it arrives in February or early March. Compare the Full Cash Value shown to recent sales of similar homes in your area. Look for evidence that your property is overvalued.
Step 2: Gather supporting evidence within 60 days of the notice mailing date. Collect comparable sales data showing similar properties sold for less, photographs documenting property condition issues, repair estimates for any defects, and recent appraisals if available.
Step 3: Complete Form 82130 (for general real property) or Form 82130R (for residential property). Include your parcel number, property details, your opinion of value, and attach all supporting documentation. You may request an informal meeting with the assessor on the form.
Step 4: File your Petition for Review with the La Paz County Assessor's Office by mail, in person, or email within the 60-day deadline. The assessor must respond by August 15. If you requested a meeting, the assessor will review your evidence and may adjust the value based on the information provided.
Step 5: If you disagree with the assessor's decision, you may appeal to the County Board of Equalization within 25 days of the date the assessor's decision was mailed. For La Paz County (population under 500,000), appeals go to the County Board rather than the State Board.
Step 6: If still unsatisfied after the County Board decision, you may appeal to Arizona Tax Court within 60 days of the Board's decision. Alternatively, you can bypass the administrative process entirely and file directly with Tax Court by December 15 of the valuation year.
Step 7: Attend your hearing and present your evidence. Whether at the informal assessor level, County Board hearing, or Tax Court, be prepared to demonstrate through comparable sales, photographs, and documentation why your property's assessed value should be reduced.
Required form: Form 82130 (Petition for Review of Real Property Valuation) or Form 82130R (Residential Petition for Review of Valuation)
