How La Paz County Assesses Property

10%of market value

Assessed by: La Paz County Assessor's Office

Assessment cycle: annual

Notices typically mailed: January through mid-March

In La Paz County, your property tax is calculated using Arizona's 10% assessment ratio for residential properties. For example, if your home's market value is $100,000 (the county median), your assessed value would be $10,000 (10% of $100,000). At La Paz County's effective rate of 0.83%, your annual property taxes would be approximately $831. This two-step system helps keep property taxes affordable and predictable for homeowners throughout the county.

The Appeal Process

Appeals are heard by the La Paz County Assessor / County Board of Equalization / Arizona State Board of Equalization. After filing your appeal, the Assessor's office will review your evidence and may schedule an informal meeting to discuss your concerns. If you proceed to a Board of Equalization hearing, you'll present your evidence before board members who will make a decision based on the documentation provided. Decisions are typically issued in writing within statutory timeframes.

1

Step 1: Review your Notice of Valuation carefully when it arrives (typically between January and mid-March). Compare your property's Full Cash Value to recent sales of similar homes in your area.

2

Step 2: Gather evidence to support your appeal within 60 days of the notice mailing date. This includes comparable property sales, photos of property condition, repair estimates for damage, or appraisals showing a lower market value.

3

Step 3: Complete the Petition for Review of Valuation form (DOR 82130R for residential properties) available from the Assessor's office or online at www.lapaz.gov. Include all supporting documentation and evidence with your petition.

4

Step 4: Submit your completed petition to the La Paz County Assessor's Office by mail or in person before the 60-day deadline. You may request an informal meeting with the Assessor to discuss your appeal. The Assessor must respond to all appeals by August 15.

5

Step 5: If you disagree with the Assessor's decision, you can appeal to the County Board of Equalization within 25 days of receiving the Assessor's decision. This requires filing additional forms with supporting evidence.

6

Step 6: If still unsatisfied after the Board of Equalization decision, you may appeal to Arizona Tax Court within 60 days of the Board's mailed decision. Tax appeals for all Arizona counties are heard at Maricopa Superior Court in Phoenix.

7

Step 7: Alternatively, property owners may bypass the administrative process entirely and file directly with Tax Court on or before December 15 of the valuation year, though this option requires paying court filing fees.

Frequently Asked Questions

What is the deadline to appeal my property taxes in La Paz County for 2026?
You must file your property tax appeal within 60 days from the date your Notice of Valuation was mailed by the La Paz County Assessor. Notices are typically mailed between January and mid-March each year. For example, if your 2026 Notice of Valuation was mailed on February 21, your appeal deadline would be approximately April 22, 2026. The mailing date is printed on your Notice of Valuation. Missing this 60-day window means you cannot appeal your assessment for that tax year and must wait until the following year. Forms are available online at the county website or by calling the Assessor's office at (928) 669-6165.
How do I file a property tax appeal in La Paz County?
To file a property tax appeal in La Paz County, first obtain the Petition for Review of Valuation form (DOR 82130R for residential properties) from the Assessor's office at 1112 Joshua Avenue Suite 204 in Parker, online at www.lapaz.gov, or by calling (928) 669-6165. Complete the form with details about why you believe your property is overvalued, and gather supporting evidence such as comparable sales data, photos, or an independent appraisal. Submit your completed petition with all evidence to the Assessor's office by mail or in person within 60 days of your Notice of Valuation mailing date. You can request an informal meeting with the Assessor to discuss your concerns, and the Assessor must provide a decision by August 15.
What exemptions are available to reduce my property taxes in La Paz County?
La Paz County offers several property tax exemptions including the Widow/Widower Exemption, Disabled Persons Exemption, Senior Property Valuation Protection (freeze), and Disabled Veteran Exemption. These exemptions can reduce or freeze your assessed value, potentially saving hundreds of dollars annually. Eligibility requirements include Arizona residency, income limits, and specific qualifying conditions such as age 65+ for senior freeze or total disability certification for disabled exemptions. All exemptions must be applied for between the first business day in January and March 1 each year at the La Paz County Assessor's Office. Contact the Assessor at (928) 669-6165 to determine which exemptions you qualify for and to obtain current year income limits and exemption amounts.
How much can I save by appealing my property taxes in La Paz County?
The amount you can save depends on how much your assessment is reduced through the appeal process. In La Paz County, with an effective tax rate of 0.83%, every $10,000 reduction in your property's assessed market value saves approximately $83 per year in property taxes. For example, if you successfully reduce your home's assessed value from $120,000 to $100,000, you would save approximately $166 annually. Successful property tax appeals nationwide save homeowners an average of $700 per year, though results vary based on the evidence presented and the validity of your claim. If your property is overvalued compared to similar homes in your area, an appeal could provide significant long-term savings.
What happens at a Board of Equalization hearing in La Paz County?
If the La Paz County Assessor denies your initial appeal, you can escalate to the County Board of Equalization within 25 days of the Assessor's decision. At the Board hearing, you will present your evidence and explain why your property valuation should be reduced. The Board members or hearing officer will review your documentation, may ask questions, and listen to the Assessor's position. Hearings are quasi-judicial proceedings where decisions are based solely on the evidence presented. The Board has authority to increase, decrease, or maintain your property's assessed value. You'll receive a written decision by mail, typically by the third Friday in November. If you disagree with the Board's decision, you can appeal to Arizona Tax Court within 60 days.
What evidence do I need for a successful La Paz County property tax appeal?
Strong evidence for a La Paz County property tax appeal includes recent comparable sales data from at least three similar properties in your area that sold for less than your assessed value, photographs documenting any damage or deferred maintenance affecting your property's value, and repair estimates from licensed contractors for needed work. A professional appraisal showing your home's market value is below the Assessor's valuation can be particularly compelling evidence. You should also review your property record card from the Assessor to identify any errors in square footage, number of bedrooms or bathrooms, or other characteristics. The more documentation you provide showing your property's true market value is lower than the assessed value, the better your chances of a successful appeal.
Can I still appeal my La Paz County property taxes if I missed the 60-day deadline?
If you miss the 60-day deadline to appeal your Notice of Valuation, you generally cannot appeal your assessment for that tax year through the standard administrative process with the County Assessor and Board of Equalization. However, you have alternative options: you can file a direct appeal to Arizona Tax Court on or before December 15 of the valuation year, bypassing the administrative process entirely (though this requires court filing fees). Another option is to file a Notice of Claim for property tax errors for the current year and up to three previous years if you believe there was an error in valuation or classification. For future years, mark your calendar when you receive your Notice of Valuation to ensure you don't miss the deadline.
How does La Paz County's property tax rate compare to other Arizona counties?
La Paz County has one of the lowest property tax burdens in Arizona, with an effective rate of 0.83% and a median annual tax bill of just $831 for a home valued at $100,000. This is significantly lower than Arizona's largest counties like Maricopa County ($1,783 average) and Pima County ($1,994 average). Only Greenlee County has a lower rate in Arizona at 0.39%. La Paz County's low median home values combined with the modest tax rate make it one of the most affordable counties for property owners in the state. The county's tax burden is also well below the national median property tax bill of $2,400, making it attractive for retirees and those seeking affordable homeownership in Arizona.
