CONTRIBUTED CONTENT: Idaho has no estate tax, so why do you still need an estate plan?

Idaho has no estate tax, no inheritance tax, and no gift tax. At the federal level, the estate and gift tax exemption sits at $15 million per person for 2026, indexed for inflation after that. Very few Idaho families will ever owe any sort of death tax.

But taxes were never the main reason to plan your estate. An estate plan decides who receives your property, who raises your children, who acts for you if you can't, and how much time and money your family spends in court.

Without a will, Idaho decides who inherits

If you die without a will, Idaho's intestacy statute (Idaho Code § 15-2-102) controls the division and distribution of your property. Your surviving spouse receives your half of the community property. Your separate property, such as assets you owned before marriage or received by gift or inheritance, is divided basically as follows:

• No children or surviving parents: all to your spouse.

• No children, but a parent survives: half to your spouse, half to your parents.

• Children who survive you: half to your spouse, half to your children.

If your spouse survives you, children from a prior relationship receive nothing from the community property. An unmarried partner receives nothing at all.

Probate is hard to avoid without a plan

Idaho's small estate affidavit lets heirs collect personal property without going to court, but only if the probate estate is worth $100,000 or less after liens and at least 30 days have passed since death. The affidavit cannot transfer real estate. If you own a home or any other real estate at death, your family will generally need a probate proceeding to transfer it.

A revocable living trust, beneficiary designations, and survivorship ownership can let assets pass outside probate. Keep beneficiary designations current: life insurance and retirement accounts generally pass to the named beneficiary regardless of what your will says.

Your will is where you name a guardian for your children

Idaho lets a parent name a guardian, and alternates, for a minor child in a will. A child 14 or older may object to the appointment. Without your nomination, a judge chooses without any input from you.

Minor children also cannot manage an inheritance themselves. A trust lets someone you choose manage the money and decide when your children receive it, instead of leaving it to a court-supervised conservatorship.

Incapacity planning matters as much as death planning

An estate plan protects you while you're alive, too. A durable financial power of attorney under Idaho's Uniform Power of Attorney Act names someone to pay bills and manage accounts. And a health care power of attorney names a health care agent and records your treatment wishes. Without these documents, your family may have to ask a court for a guardianship or conservatorship – a slow and costly process that is not kept private within the family.

Marriage alone doesn't solve this. Idaho generally requires both spouses to join in selling or mortgaging community real estate, so one spouse's incapacity can stall a home sale or refinance.

Federal tax rules still reward planning

Two federal rules still matter:

• Portability. A surviving spouse can use the deceased spouse's unused federal estate tax exemption, but only if the estate files a timely federal estate tax return (Form 706) making the election. This is only necessary for couples who have enough wealth to be subject to the federal estate tax, but it makes a massive difference if it applies to you.

• Basis step-up on community property. When the first spouse dies, both halves of community property generally receive a new income tax basis equal to fair market value in Idaho. That can sharply reduce capital gains tax when the surviving spouse sells the real estate later.

The bottom line

Idaho's lack of an estate tax is good news, but it doesn't decide who inherits, who cares for your children, or who speaks for you in a crisis. A basic plan, typically a will or trust, powers of attorney, an advance health care planning document, and updated beneficiary designations, handle all of that. Don’t leave any of this to chance and don’t assume you can take care of it at some point down the line…down the line shows up quicker than many realize.
