La Paz County is Arizona's second-least populous county with a population of approximately 16,700, located along the Colorado River in western Arizona. The county seat is Parker, and the primary municipalities include Parker and Quartzsite. With a median home value of approximately $100,000 and an effective tax rate of 0.83%, La Paz County property taxes are significantly below both state and national averages, making property tax appeals an important tool for homeowners looking to reduce what is already a relatively modest tax burden in this rural desert community.

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.

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.

How La Paz County Assesses Property

10%of market value

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.

1

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.

2

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.

3

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.

4

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.

5

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.

6

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.

7

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)

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 Value was mailed by the La Paz County Assessor. Since notices are typically mailed in February by March 1, most appeal deadlines fall in late April or early May 2026. The exact deadline is printed on your Notice of Value card. Missing this deadline means you'll have to wait until the next tax year to appeal, so mark your calendar immediately upon receiving your notice and don't delay gathering your evidence.
How do I file a property tax appeal in La Paz County?
To file an appeal in La Paz County, complete Form 82130 for general real property or Form 82130R for residential property, available from the assessor's website at lapaz.gov. Include your parcel number, evidence such as comparable sales, photos, and repair estimates, and your opinion of the correct market value. Submit the form by mail to 1112 Joshua Avenue Suite 204, Parker AZ 85344, deliver it in person during office hours (Monday-Thursday 7am-6pm), or email to assessor@lapaz.gov within 60 days of your Notice of Value mailing date. You can request an informal meeting with the assessor on the form.
What happens after I file my property tax appeal with the La Paz County Assessor?
After you file your Petition for Review, the La Paz County Assessor's office will review your appeal and any supporting evidence you provided. If you requested an informal meeting, they will schedule a time to discuss your concerns. The assessor must respond to your appeal by August 15 of the same year. If the assessor agrees with your appeal, your property value will be adjusted and no further action is needed. If you disagree with the assessor's decision, you have 25 days from the date their decision was mailed to appeal to the La Paz County Board of Equalization for a formal hearing.
What evidence do I need for a successful property tax appeal in La Paz County?
The most compelling evidence for a La Paz County property tax appeal includes recent comparable sales of similar homes in your area that sold for less than your assessed value, demonstrating your property is overvalued relative to the market. Also gather photographs showing property condition issues, deferred maintenance, or damage that affects value. Obtain repair estimates from licensed contractors for any needed work. If your home has unique characteristics or limitations not captured in the assessor's records, document these thoroughly. Recent professional appraisals also carry significant weight if you have one. The key is showing the assessor's Full Cash Value exceeds true market value based on objective evidence.
How much can I save by appealing my property taxes in La Paz County?
According to available data, successful property tax appeals in La Paz County result in average savings of approximately $650 annually. Your actual savings will depend on how much you're able to reduce your assessed value and your specific tax rate. For example, if you reduce your Full Cash Value by $50,000, your assessed value drops by $5,000 (at the 10% assessment ratio), which would save you approximately $415 annually at La Paz County's 0.83% effective rate. Given that the median tax bill in La Paz County is only $831, a successful appeal can reduce your annual property tax burden by a significant percentage.
What property tax exemptions are available in La Paz County?
La Paz County offers several exemptions for qualifying residents. The widow/widower and totally disabled exemptions provide a $4,873 reduction in assessed value for 2026 if your household income is below $39,865 and total assessed property value doesn't exceed $36,454. Disabled veterans receive a prorated exemption based on their VA disability percentage, with 100% service-connected disabled veterans receiving a full exemption on their primary residence with no cap. Applications must be filed between January 2 and March 1 each year at the La Paz County Assessor's Office. These exemptions can reduce your tax bill by $150 to $500 or more depending on your situation and the local tax rate.
Can I appeal directly to court instead of going through the La Paz County Assessor first?
Yes, Arizona law allows property owners to bypass the administrative appeal process and file directly with Arizona Tax Court. If you choose this option, you must file your appeal with the Maricopa Superior Court (which hears all Arizona tax court cases) by December 15 of the valuation year - the same year you received your Notice of Value. This judicial method is available whether you're appealing an assessment on your primary residence or other property types. However, most homeowners find it beneficial to start with the informal administrative process at the county level, as it's free, less formal, and many issues are resolved without needing to go to court. You can always escalate to Tax Court later if needed.
Does La Paz County reassess property values every year?
Yes, La Paz County conducts annual assessments of all properties. The assessor is required to value properties as of January 1 each year for the following tax year and must mail Notice of Value cards to property owners by March 1. However, Arizona law provides important protections through the Limited Property Value system, which caps annual increases at 5% even if your Full Cash Value (market value) rises more dramatically. This means while your property is reassessed annually, your actual taxable value is protected from sudden large increases. If you believe your Full Cash Value is incorrect in any given year, you have the right to appeal within 60 days of receiving your notice.
