Arizona Estate Tax Calculator (2026 Exemption Limits & Inheritance Liabilities)

Arizona's record in the engine's 2026 state estate tax table sets hasEstateTax to false, with an exemption of $0 and no brackets. The primitive checks that flag first and returns before any rate is applied.

At the default $5,000,000 gross estate the calculator returns $0.00 of Arizona estate tax, an effective rate of 0.00%, an exemption threshold of $0, and $5,000,000.00 distributed to heirs. Every other estate value produces the same tax figure. The tool is behaving correctly; Arizona simply supplies nothing for it to compute.

No Arizona estate tax entry means no exemption to clear and no bracket ladder to walk.

1. Value the gross estate. Date-of-death fair market value of all real property, business interests, securities, cash, and life insurance proceeds. The calculator accepts the figure as entered.
2. Subtract allowable deductions. The deductions box comes off the gross and the result is floored at zero. That subtraction runs in the config; the state test it feeds has a fixed answer in Arizona.
3. Look Arizona up in the state estate tax table. The lookup returns hasEstateTax: false, so the function exits with a tax of $0, an exemption threshold of $0, and a taxable estate above exemption of $0.
4. Return $0. The net estate reaches beneficiaries with no Arizona reduction at any size.

1. Start with the gross estate. A $5,000,000 gross estate at fair market value, before deductions.
2. Check Arizona's table entry. No estate tax and no brackets, so no threshold or schedule is loaded.
3. Compute the state estate tax due. $0.00.
4. Distribute the net estate. The full $5,000,000.00 passes to beneficiaries.
5. What this excludes. Arizona's state-level result only; the federal return is separate and appears nowhere in this figure.

Each line is a distinct run of this calculator.

At a $1,000,000 estate. Arizona estate tax = $0.00; net to heirs $1,000,000.00.

At a $10,000,000 estate. Arizona estate tax = $0.00; net to heirs $10,000,000.00.

At a $15,000,000 estate. Arizona estate tax = $0.00. At $15,001,000, one thousand dollars further on, still $0.00. The step costs $0.00.

At a $25,000,000 estate. Arizona estate tax = $0.00; net to heirs $25,000,000.00.

At a $50,000,000 estate. Arizona estate tax = $0.00; net to heirs $50,000,000.00.

The marginal cost of the next $1,000,000 of estate value is $0.00 at every point in the range, and the effective rate stays at 0.00% from the bottom of it to the top. The reverse question -- how much can pass before Arizona takes a share -- has no answer in dollars, because the branch that computes a share is never reached.

That flat line is the finding, not a missing feature. On a state with a genuine exemption cliff, the values either side of the threshold differ; here $14,999,000 and $15,001,000 return the identical $0.00.

It is reasonable to suspect the zero is being produced by generous deductions. It is not, and the calculator will demonstrate that in three runs.

Deductions at $0 on a $5,000,000 gross estate: tax $0.00, net distributed $5,000,000.00. Deductions at $1,000,000: tax $0.00, net distributed $4,000,000.00. Deductions at $5,000,000: tax $0.00, net distributed $0.

Net distributed tracks the deduction dollar for dollar. The tax line never moves. The total Arizona estate tax saved by claiming the largest deduction tested is $0.00.

The Statutory Exemption Threshold output reads $0 on this page. Read literally that suggests Arizona exempts nothing and taxes everything, which is exactly backwards.

The primitive fills that field with a statutory number only when a state has an estate tax. Arizona's early return sets it to $0 as a null value, together with hasEstateTax: false and a taxable estate above exemption of $0. The distinguishing evidence is the tax figure beside it: a regime that really taxed from the first dollar would show a threshold of $0 and a substantial tax, whereas here the tax at $50,000,000 is $0.00.

The engine contains no federal estate tax computation. No federal exemption exists in its 2026 tables, and it applies no unified credit, no portability of a deceased spouse's unused exclusion, no add-back of lifetime taxable gifts, and no generation-skipping transfer tax.

A $50,000,000 estate returning $0.00 here therefore reports a zero Arizona bill against an entirely uncomputed federal position. Anyone using this page as a total transfer tax estimate is reading it for something it does not contain.

Arizona is also absent from the engine's separate 2026 state inheritance tax table, which holds records for Pennsylvania, Nebraska, Maryland, Kentucky, and New Jersey only. Those are different taxes on different payers, so one being zero would not settle the other; in Arizona's case neither table generates a charge.

The calculator models a single state. Real property located in a state that does levy an estate tax is taxable there on that state's own schedule, whatever the decedent's domicile, and there is no input on this page to represent it. An Arizona estate holding out-of-state real property gets $0.00 here and an uncomputed liability elsewhere.

• Federal estate tax under IRC Chapter 11. Not computed, and no federal exemption figure exists in the engine's tables.
• Federal generation-skipping transfer tax under IRC Chapter 13. Not computed.
• Out-of-state situs and apportionment. One state per run, with no allocation of value between jurisdictions.
• Valuation discounts. Minority-interest and marketability adjustments on closely held entities are not applied.
• Community property characterisation. The calculator takes one gross estate figure and has no input for splitting value between spouses.

• Reading the $0 exemption threshold as a taxable-from-dollar-one regime. The tax beside it is $0.00 at $50,000,000.
• Assuming deductions produced the zero. With deductions at $0 the answer is $0.00; with deductions at $5,000,000 it is $0.00.
• Taking the headline as the whole death tax bill. No federal figure is included.
• Expecting out-of-state property to be covered. It is not modelled at all.
• Waiting for a threshold at higher values. The sweep runs to $50,000,000 and the answer never changes.
