How Much Can Property Taxes Increase in Arizona? 2026 Complete Guide

Updated March 2026

Quick Answer

Arizona has multiple protections limiting property tax increases:

• 5% annual cap on primary residence assessed value increases
• 10% annual cap on commercial and secondary homes
• 2% annual limit on tax levies for existing properties (with voter overrides)
• Constitutional expenditure limit restricts government spending

This makes Arizona one of the more taxpayer-friendly states, especially compared to no-cap states. However, these protections reset when you buy, and voter-approved overrides can still increase your bill.

Arizona's Property Tax Protection System

Arizona uses a multi-layered approach to limit tax increases:

1. Assessment Value Caps (Prop 117)

• Primary residences: 5% annual increase maximum
• All other property: 10% annual increase maximum
• Based on "Limited Property Value" (LPV)
• Resets to Full Cash Value on sale

2. Levy Limits

• 2% cap on increased taxes from existing property
• New construction excluded from cap
• Voter overrides can exceed limit
• School district bonds exempt

3. Constitutional Spending Limits

• State and local government spending capped
• Based on population + inflation
• Provides overall fiscal restraint
• Can be overridden by vote

The 5% Assessment Cap Explained

Since 2015, Arizona has protected homeowners with strict caps:

How It Works

1. Your Limited Property Value (LPV) can only increase 5% per year
2. Taxes are calculated on LPV, not market value
3. The gap between LPV and market value can grow over time
4. Protection continues until property sells

Example Scenario

• 2020 Purchase: $400,000 (LPV = Full Cash Value)
• 2021: Market value $450,000, LPV = $420,000 (5% increase)
• 2022: Market value $500,000, LPV = $441,000 (5% increase)
• 2023: Market value $550,000, LPV = $463,050 (5% increase)
• 2024: Market value $600,000, LPV = $486,203 (5% increase)

Tax savings: Based on $113,797 less value!

Limited Property Value vs. Full Cash Value

Understanding these two values is crucial:

Full Cash Value (FCV)

• Market value as determined by assessor
• What your property would sell for
• Can increase without limit
• Used for new purchases

Limited Property Value (LPV)

• Capped value for tax purposes
• Increases maximum 5% (residential) or 10% (other)
• Creates growing "protection gap"
• Resets to FCV on sale

The Protection Gap

In hot markets like Phoenix/Scottsdale:

• 10-year owners might have 40-50% gaps
• Saves thousands annually
• Major consideration when selling
• New buyer pays on full value

When Caps Don't Apply

Several situations eliminate cap protection:

1. Property Sale/Transfer

• Resets to Full Cash Value
• New owner starts fresh
• Even family transfers may trigger
• Check exemptions carefully

2. New Construction

• Additions over $5,000
• Major improvements
• Reassessed at completion
• Partial reset possible

3. Voter-Approved Overrides

• School bonds
• Municipal overrides
• Special districts
• Can add significantly to bill

4. Change in Use

• Converting residential to rental
• Commercial use changes
• Loses 5% cap, gets 10%

Real-World Impact

Let's examine actual scenarios:

Phoenix Metro Growth

Recent market conditions:

• Home values increased 40-60% (2020-2023)
• Protected properties saw 5% annual tax value increases
• New buyers faced full market assessments
• Long-term owners saved $3,000-5,000 annually

Example: Scottsdale Homeowner

• Bought 2015: $500,000
• 2024 market value: $850,000
• 2024 LPV: ~$660,000
• Annual tax savings: ~$2,800

Example: Tucson Retiree

• Bought 2010: $250,000
• 2024 market value: $400,000
• 2024 LPV: ~$335,000
• Annual tax savings: ~$650

New Buyer Reality Check

• 2024 Purchase: $600,000
• Neighbor's identical home LPV: $450,000
• New buyer pays ~$1,500 more annually
• No protection until future years

Comparison to Other States

Arizona Advantages

• More generous than California (5% vs 2%)
• Broader than Florida (all residential, not just homestead)
• Simpler than Texas (one rate, clear rules)
• More stable than Colorado (constitutional protection)

Arizona Disadvantages

• No portability like Florida
• Higher cap than California
• Full reset on sale (no inheritance protection)
• Overrides common in growing areas

What This Means for You

If You're a Current Homeowner

1. Enjoy protected increases - 5% predictability
2. Budget accordingly - Still plan for increases
3. Consider staying put - Gap grows annually
4. Watch for overrides - Vote participation matters

If You're Buying in Arizona

1. Expect full assessment - No inherited protection
2. Research tax history - Check override patterns
3. Factor in 5% growth - Future budgeting
4. Compare total costs - Not just purchase price

Strategic Considerations

For Long-Term Residents:

• Protection compounds over time
• Moving costs you tax savings
• Renovate carefully (permits = reassessment)
• Estate planning matters (transfers reset)

For Investors:

• 10% cap still provides protection
• Rental properties get commercial rate
• Factor into ROI calculations
• Consider hold strategies

Take Action Now

Whether buying or owning in Arizona:

1. Understand Your Values - Check both LPV and FCV
2. Calculate Your Gap - Know your protection level
3. Appeal If Overvalued - Even with caps, accuracy matters
4. Plan Major Decisions - Sales and improvements reset values

Frequently Asked Questions

How much can my Arizona property taxes actually increase each year?

Your assessed value can increase maximum 5% (primary residence) or 10% (other property). However, your tax bill can increase more if voters approve bonds, overrides, or rate increases.

What happens if I add a pool or addition?

Improvements over $5,000 trigger reassessment of that portion. Your base property keeps its cap, but the addition is assessed at current market value.

Can I transfer my tax protection to a new home?

No, Arizona doesn't offer portability like Florida. When you sell, you lose accumulated protection and start fresh at the new property.

Do I still need to appeal if I have the 5% cap?

Yes! The cap limits increases but doesn't fix overvaluation. If your Full Cash Value is too high, you're still overpaying. Appeals can reduce both values.

How does Arizona's system compare for retirees?

Mixed results:

• Pro: 5% cap provides predictability
• Pro: Lower rates than many states
• Con: No senior freezes like some states
• Con: No portability for downsizing

What areas have the most overrides?

Generally:

• Growing suburbs (Queen Creek, Gilbert, Peoria)
• High-performing school districts
• Infrastructure-heavy areas
• Tourist destinations (Sedona, Flagstaff)
