An irrevocable trust is the one you cannot take back. Assets placed in it genuinely leave your control - that is not a flaw, it is the mechanism. Because the property is no longer yours, it can sit outside your taxable estate, beyond most creditors, and outside certain benefit calculations. Real power, real price. The question is whether you have one of the few problems it solves.
The federal estate tax does not start until
$15,000,000
per person for deaths in 2026, per the IRS. Below that line, the tax-driven case for an irrevocable trust mostly is not there - and Arizona itself has no estate tax at all.
The problems it genuinely solves
- Estates above the federal exemption - moving assets and their growth out of the taxable estate.
- Long-term-care planning - positioning assets ahead of ALTCS rules, years in advance, with specialist guidance.
- Asset protection - for people in high-liability work, shielding what is placed in trust.
- Life insurance trusts - keeping a large policy's payout outside the estate.
- Special-needs planning - providing for a beneficiary without disqualifying their benefits.
What it costs you
Control, permanently. Under A.R.S. § 14-10602, a trust is revocable unless it expressly says otherwise - the irrevocable version says otherwise on purpose. You cannot simply pull the house back out because plans changed. This is why the honest starting point for most families is the revocable trust: it solves the common problems (probate, privacy, incapacity, staged inheritances) while you keep every ounce of control.
The honest test
If your reason is "avoid probate" or "keep things private," the revocable trust does that - see the trust guide. If your reason involves the federal exemption, nursing-home planning, professional liability, or a special-needs beneficiary, the irrevocable trust belongs in the conversation, and that is a conversation for a specialist, not a form.
