Arizona has no state inheritance tax and no state estate tax. Maricopa County Superior Court Probate Division (201 W. Jefferson St., Phoenix) handles Phoenix estate administration. Arizona offers small estate affidavit procedures for estates under $75,000 in personal property, and summary administration for total estates under $75,000, allowing many inherited Phoenix properties to transfer title with simplified procedures. For larger estates, full probate typically runs 6 to 12 months in Maricopa County.
Arizona Inheritance Tax: No State Tax for Phoenix Heirs
Arizona has no state inheritance tax and no state estate tax. Heirs who inherit a Phoenix property owe no Arizona state tax on the inheritance. Federal estate tax applies only to estates exceeding $13.99 million in 2026.
Capital gains and stepped-up basis: The inherited property’s cost basis steps up to fair market value at date of death. A sale shortly after inheriting at or near that value produces minimal capital gains tax. Appreciation above the stepped-up basis is taxed at federal capital gains rates if the property is held and later sold for more.
Arizona community property and inheritance: Property inherited during a marriage is separate property in Arizona — it does not become community property. The inheriting spouse’s non-inheriting spouse has no community property claim on the inherited Phoenix home.
Maricopa County Probate: From Summary Administration to Full Probate
Option 1: Small estate affidavit (ARS § 14-3971). Available when the decedent’s personal property does not exceed $75,000 and real property does not exceed $100,000. Heirs can use an affidavit to collect personal property 30 days after death and record a transfer of real property — no probate court required. This is the most streamlined option for small Phoenix estates.
Option 2: Summary administration (ARS § 14-3973). Available when the total estate (after debts) is $75,000 or less. The court can issue summary administration without full probate proceedings.
Option 3: Full probate — Maricopa County Superior Court Probate Division. For estates exceeding the thresholds above, or for contested estates. The Probate Division is located at 201 W. Jefferson Street, Phoenix, AZ 85003.
Full Arizona probate process:
- File petition to admit will to probate or establish intestacy
- Appointment of personal representative (named in will) or administrator (intestacy)
- Letters Testamentary or Letters of Administration issued
- Notice to creditors — published in a newspaper of general circulation for 3 consecutive weeks; creditors have 4 months after first publication to file claims
- Inventory and appraisement of estate assets (ARS § 14-3706)
- Estate administration — personal representative manages, sells, and distributes estate assets
- Final accounting and petition for distribution
Timeline: Uncontested full probate in Maricopa County typically runs 6 to 12 months. Contested estates, multiple properties, or complex asset structures can run 12 to 24 months.
Key difference from Texas: Arizona does not have the “independent administration” concept in the same form as Texas. Arizona’s personal representative must comply with formal estate administration requirements but generally can sell real property after court appointment without individual sale orders for each transaction (under informal probate proceedings).
The Phoenix Heat Risk for Inherited Properties
For inherited Phoenix properties that are left vacant:
HVAC failure in a vacant Phoenix home in summer is catastrophic. At exterior temperatures of 110°F to 115°F, a Phoenix home without working HVAC reaches interior temperatures of 130°F+ within hours. This causes:
- Flooring buckling (wood, laminate, and some tile adhesives fail at extreme heat)
- Paint blistering on interior and exterior surfaces
- Plumbing joint failure from thermal expansion
- Water heater and appliance damage
Cost of HVAC operation in a vacant Phoenix home during summer: $200 to $450 per month (May through September).
If HVAC fails in a vacant inherited property: Emergency HVAC service in Phoenix during summer can cost $500 to $2,000+ just for the service call, and replacement units are on long backlogs during peak season. Operating a vacant property through a Phoenix summer without a reliable HVAC plan is a serious risk.
The cash sale solution: We purchase inherited Phoenix properties as-is, including properties with HVAC issues, deferred maintenance, and summer condition damage. The inherited property is assessed in its current condition and the offer reflects that — rather than requiring heirs to manage an HVAC crisis 3,000 miles away.
Real Monthly Carrying Costs on an Inherited Phoenix Home
For a $380,000 inherited Phoenix home with no mortgage:
| Expense | Monthly Range |
|---|---|
| Maricopa County property taxes | $250–$380 |
| Vacant home insurance | $175–$350 |
| HVAC (summer months) | $200–$450 |
| HVAC (off-season) | $50–$100 |
| Pool maintenance (if applicable) | $150–$300 |
| Lawn/desert landscaping | $75–$150 |
| General maintenance | $100–$200 |
| Total (summer, with pool) | $950–$1,830 |
Maricopa County property taxes: Arizona uses a limited property value (LPV) system. Residential properties (Class 3) are assessed at 10% of LPV. The effective tax rate on full market value runs approximately 0.6% to 0.9% — significantly lower than Texas (2.0%–3.0%) but still meaningful for non-owner-occupied properties.
