How Much Can Property Taxes Increase in Arizona? 2026 Complete Guide
Updated July 2026
Quick Answer
Arizona caps property taxes on two sides at once. Since Proposition 117 took effect in tax year 2015, the taxable value of every locally assessed property, called the Limited Property Value or LPV, can rise no more than 5% per year. There is no separate 10% tier for commercial property or second homes: the 5% cap applies to all of it. On the other side, the Arizona Constitution limits counties, cities, and community college districts to 2% annual growth in their primary property tax levy, plus new construction. Voter-approved overrides and bond levies sit outside that cap, which is why your bill can still climb faster than 2% in some years.
One more thing that surprises people moving from California: Arizona's cap does not reset when a home sells. The capped LPV passes to the buyer.
Most homeowners never challenge their assessment, usually because nobody tells them they can or shows them how. That gap is the whole reason AppealDesk exists: see what your county has your home on record at, free, and if the number looks wrong we build the case for $49.
Arizona's Limited Property Value and the 5% Annual Increase
Arizona assigns every property two values each year. The Full Cash Value (FCV) is the assessor's estimate of what the property is worth on the market, and it can move without limit. The Limited Property Value (LPV) is the value your taxes are actually calculated from, and under Proposition 117 (approved by voters in 2012, effective tax year 2015, codified at A.R.S. 42-13301) it can grow at most 5% per year. Since 2015, both primary taxes and secondary taxes, meaning bonds and voter-approved overrides, are levied on LPV only. Full Cash Value never appears on the math side of your bill anymore; it mostly matters as the ceiling LPV can never exceed and as the value you argue about in an appeal.
Because the 5% cap compounds while market values can jump 15% or 20% in a hot year, a gap tends to open between what your home would sell for and what you are taxed on. A home with an LPV of $300,000 this year can carry an LPV of at most $315,000 next year, no matter what the Phoenix or Tucson market did. That predictability is the whole point of the cap.
Here is the part many guides get wrong, including an earlier version of this one: the LPV does not reset when the property sells. Arizona is not California. Under Prop 13, a California home is reassessed to its purchase price when it changes hands. In Arizona, the buyer inherits the seller's capped LPV, and the 5% limit keeps running as if nothing happened. There is no penalty for buying, no fresh start at market value, and no reason to fear a tax spike simply because you closed on a house. Two identical neighboring homes generally do not carry wildly different taxable values just because one sold recently.
A fresh valuation only happens in a handful of situations spelled out in statute, known as "Rule B" valuations: new construction, additions or modifications, a parcel split or combination, a change in how the property is used, or property that was omitted from the roll entirely. In those cases the assessor does not simply use market value. Rule B sets the new LPV at the county's average ratio of LPV to Full Cash Value for similar property in the same class, which frequently lands the new value below a straight market number.
The 2% Levy Limit: Why Your Bill Can Still Go Up
The value cap is only half the system. The Arizona Constitution (article IX, section 19, implemented at A.R.S. 42-17051) also limits how much revenue counties, cities, and community college districts can raise from their primary property tax levy: at most 2% more than the prior year, plus whatever new construction added to the roll. This is a limit on the government's total take, not on your individual bill, but it acts as a brake on rates. When capped values rise across a county, the levy limit forces primary rates down to keep total collections inside the 2% envelope.
The exceptions matter. Voter-approved overrides, school district bonds, and other secondary levies sit outside the 2% limit. If your district passes a budget override or a new bond, that amount lands on your bill on top of everything the caps control. So the honest answer to "do property taxes go up every year in Arizona?" is: your taxable value usually rises up to 5%, your local governments' base levies rise up to 2% plus growth, and anything voters approve gets added on top. Most Arizona homeowners see modest annual increases, not flat bills.
Caps and rate limits only control how fast your bill can grow. Nothing in them checks whether the number underneath is right. Assessors in Arizona set values with mass-appraisal models that price thousands of homes at once, and nobody reviews yours unless you challenge it.

What Is Arizona's Property Tax Rate in 2026?
Arizona has no single statewide property tax rate. Your bill is built in three steps: the LPV, times an assessment ratio set by property class, times the combined rates of every jurisdiction that taxes your parcel (county, city, school district, community college, and any special districts). For an owner-occupied primary residence, Class 3, the assessment ratio is 10% of LPV. A $400,000 LPV therefore produces a $40,000 assessed value, and a combined rate of, say, $10 per $100 of assessed value would mean a $4,000 bill before rebates. Owner-occupied homes also receive the state Homeowner Rebate, which offsets part of the school district primary tax automatically.
Commercial and industrial property, Class 1, is assessed at a higher ratio: 15.5% of LPV for tax year 2026, stepping down to 15.0% in 2027 as the final year of the phase-down enacted in 2022 under SB 1093. Residential rentals are Class 4 and are assessed at 10%, the same ratio as owner-occupied homes, not the commercial ratio.
Actual combined rates vary widely by location. Maricopa County parcels in Phoenix, Scottsdale, or Mesa carry different totals than Pima County parcels in Tucson, because each overlapping district sets its own rate each August. Rather than quote figures that shift every year, pull your own parcel: every county treasurer posts the exact rates applied to your bill, and your annual Notice of Value shows both values the math starts from. As a rough national reference, Arizona's effective rates on owner-occupied homes consistently rank below the U.S. average, helped by the 10% ratio and the Homeowner Rebate, but the precise figure for your address depends entirely on your districts.
Does Arizona Charge More Property Tax for a Second Home?
Somewhat, yes, but not the way most people assume. A second home or a residential rental falls into Class 4 instead of Class 3. The assessment ratio is identical, 10% of LPV, and the 5% cap applies exactly the same. The difference is the Homeowner Rebate: it applies only to owner-occupied primary residences, so a second home pays the full school primary tax with no state offset. The result is a moderately higher bill on the same value, not a punitive second-home rate. If you convert a rental back into your primary residence, tell the assessor so the classification and rebate follow.
Do Additions and ADUs Increase Property Taxes in Arizona?
Yes. New construction is one of the events that triggers a Rule B valuation. When you add square footage, build a casita or ADU, or make significant modifications, the assessor values the changed property using the county's average LPV-to-FCV ratio for similar property, rather than simply stacking market value on top of your capped base. Your existing cap protection is not wiped out; the property is revalued under the statutory formula, and the 5% cap resumes from the new LPV going forward. You may see older articles cite a specific dollar threshold that triggers reassessment; we could not verify one in current law, so treat any addition or permitted improvement as something your assessor will pick up, and check with your county assessor before assuming a project stays off the roll.
The Senior Freeze and Arizona's Homestead Exemption in 2026
Arizona does have a senior freeze, contrary to what some older guides claim. The Senior Property Valuation Protection Option, added to the constitution by Proposition 104, freezes the LPV of a primary residence for owners age 65 or older who have lived in the home at least two years and whose average household income over the past three years falls under the limit. For 2026, the inflation-adjusted limits are $47,712 for a single owner and $59,640 when two or more owners share title. The freeze lasts three years and is renewable; apply through your county assessor. A frozen LPV does not freeze the tax rate, so bills can still move a little, but it stops the 5% annual value climb entirely for qualifying seniors.
One clarification searchers frequently need: Arizona's "homestead exemption" is not a property tax break. It is creditor protection, shielding a chunk of your home equity from certain judgments. If you are looking for property tax relief, the tools are the Homeowner Rebate on Class 3 homes, the senior freeze described above, and, when your value is simply too high, an appeal.

Proposition 117 caps the Limited Property Value, the figure your bill is actually built on.
A cap limits how fast the number grows. It does not check whether the number was right to begin with.
What you can do about it
What the Caps Do Not Check: Your Actual Value
Everything above limits how fast values and levies grow. None of it asks whether the starting value is correct. If the assessor's Full Cash Value for your home is inflated, the 5% cap just compounds an inflated number forever, and every future bill inherits the error. The cap is a speed limit, not an audit.
Arizona values a year ahead, which trips people up. The Notice of Value mailed in February or March sets your value for the following tax year; the notice mailed in early 2026 governs your 2027 taxes. You have 60 days from the mailing date on the notice to file a Petition for Review with your county assessor. In Maricopa County, for example, the 2027 notices went out February 20, 2026, making that deadline April 21, 2026. The assessor must answer by August 15. If you are denied, you can go to the State Board of Equalization (in Maricopa and Pima counties) or your County Board of Equalization within 25 days of the assessor's decision, or file directly in Arizona Tax Court by December 15. Because the whole cycle runs roughly 18 months ahead of the bill, the time to challenge a bad value is when the notice arrives, not when the bill does.
A real AppealDesk order, Maricopa County
In May 2026, a homeowner in Maricopa County ran the check. The county had their home on record at $2,331,000, while recorded sales of comparable homes supported about $1,830,550: an over-assessment of $500,450, worth roughly $1,092 per year if corrected. Their packet laid out the comparable sales, the forms, and the filing steps. Nobody at the county was ever going to run that check for them.
Growth limits only help if the number they grow from is fair. If your assessment jumped after a purchase, new construction, or a revaluation, that new number is the one nobody has reviewed. Checking it is free and takes about a minute.

Frequently Asked Questions
Do property taxes go up every year in Arizona?
Usually, but within guardrails. Your Limited Property Value can rise at most 5% per year, county and city primary levies can grow at most 2% plus new construction, and voter-approved overrides or bonds can add more. Most homeowners see steady, modest increases rather than sudden jumps.
Does my taxable value reset when I buy a home in Arizona?
No. The seller's capped LPV transfers to you and the 5% cap keeps running. Only new construction, parcel splits, a change of use, or omitted property trigger a fresh Rule B valuation, and even then the formula uses the county's average LPV-to-FCV ratio, not raw market value.
What happens to my taxes if I add a pool, addition, or ADU?
Permitted improvements are picked up as new construction and valued under Rule B. Your value goes up to reflect the improvement, then the 5% cap resumes from the new LPV. Check with your county assessor about how a specific project will be treated.
Is there a property tax break for seniors in Arizona?
Yes. The Senior Property Valuation Protection Option freezes the LPV for three renewable years for owners 65 and older who meet the residency and income tests. For 2026 the income limits are $47,712 for one owner and $59,640 for two or more owners.
Do I still need to appeal if I have the 5% cap?
If your value is wrong, yes. The cap limits growth but never verifies the underlying number. A successful appeal lowers the value every future capped increase compounds from, so the savings repeat year after year.
