Arizona is one of the most tax-friendly states for homeowners in the US, with an average effective property-tax rate of just 0.51% of market value — 49th out of 50 states according to the Tax Foundation’s 2024 State Business Tax Climate Index and ATTOM Data Solutions property-tax analysis. On a $350,000 home that works out to roughly $1,785 per year, or $149 per month — far below the national median. This calculator lets you enter any home value, apply the statewide average or a county-specific preset, and see your estimated annual and monthly bill in seconds.
How Arizona property tax works
Arizona property tax is levied on the assessed value of the property, not the full market price. For residential homes, the assessed value equals 10% of the Limited Property Value (LPV) — a figure the county assessor calculates and that is capped by Arizona Revised Statutes §42-13302 at no more than 5% growth per year, regardless of how fast the broader market moves.
The annual tax bill is then:
Annual Tax = Assessed Value x Combined Levy Rate
where the levy rate is set each year by adding together all applicable overlapping taxing jurisdictions: the state, the county, the city or town, the school district, and any special districts (fire, flood control, community facilities). Because Arizona’s LPV cap keeps assessed values below soaring market values during housing booms, the effective rate against market value stays low — the 0.51% figure this calculator uses.
Worked example
A homeowner buys a $400,000 primary residence in Phoenix (Maricopa County, effective rate ~0.57%):
- Annual property tax estimate: $400,000 x 0.0057 = $2,280
- Monthly escrow component: $2,280 ÷ 12 = $190
- Approximate LPV-based assessed value (10% ratio): ~$40,000
Now compare the same $400,000 home across three Arizona counties:
| County | Effective rate | Annual tax | Monthly |
|---|---|---|---|
| Graham County | 0.45% | $1,800 | $150 |
| Arizona avg | 0.51% | $2,040 | $170 |
| Maricopa (Phoenix) | 0.57% | $2,280 | $190 |
| Coconino (Flagstaff) | 0.55% | $2,200 | $183 |
| Pima (Tucson) | 0.62% | $2,480 | $207 |
| Yuma County | 0.71% | $2,840 | $237 |

Why Arizona property taxes are low
Three structural features keep Arizona’s property taxes among the lowest in the US:
- LPV growth cap. The Limited Property Value cannot rise more than 5% in any single year, disconnecting assessed value from fast-rising market prices (ARS §42-13302).
- 10% residential assessment ratio. Only 10% of LPV counts as the taxable base, versus up to 18% for commercial and 15% for agricultural land.
- Primary-residence classification. Owner-occupied homes automatically receive the 10% ratio and are protected from the higher commercial rate.
In addition, Arizona’s Senior Property Valuation Protection programme freezes the LPV for qualifying homeowners aged 65 or older, and separate exemptions exist for widows/widowers and people with disabilities. These reductions must be applied for through your county assessor and are not reflected in this calculator’s estimates.
Note: This calculator estimates tax based on market value using an effective rate, which is a simplified approach. Your actual bill depends on the LPV your assessor assigns, all applicable district levies, and any exemptions you claim. Verify with your county assessor for an exact figure.
