Estate Planning in Idaho
Idaho is a community property state with a double step-up in basis and one of the few states recognizing electronic wills. But there's a critical gap: Idaho does NOT allow transfer-on-death deeds for real property. Every neighboring state does. For Idaho families who own a home, ranch, or land, a living trust isn't optional — it's the only way to avoid probate for real estate.

What most people don't know about Idaho
Idaho is a community property state — but unlike every one of its neighboring states, it does NOT allow transfer-on-death deeds for real property. Washington, Oregon, Montana, and Nevada all permit TOD deeds that transfer a home directly to a beneficiary at death without probate. Idaho doesn't. If your family home, ranch, or land isn't held in a trust, community property with right of survivorship (CPWROS), or joint tenancy, it must go through probate. This is the single biggest reason Idaho families need a living trust — a gap that many people don't discover until it's too late.

Plain English Rules
- •Idaho does NOT allow transfer-on-death deeds for real property — unlike all neighboring states; a trust, CPWROS, or joint tenancy is required to avoid probate for real estate
- •As a community property state, Idaho provides a double step-up in basis — both halves of community property reset to fair market value when one spouse dies, potentially saving tens of thousands in capital gains tax
- •Idaho recognizes electronic wills — one of a small number of states allowing wills created, signed, and witnessed in digital format
- •Holographic wills are valid if the signature and material provisions are in the testator's handwriting — no witnesses needed
- •Community property passes entirely to the surviving spouse under intestacy; separate property gives the spouse half if there are children or surviving parents
- •Idaho has no state estate tax or inheritance tax — only the federal estate tax applies to very large estates
What Actually Breaks
Real property not in trust, CPWROS, or joint tenancy
Must go through full probate — Idaho does not allow TOD deeds for real estate, unlike all neighboring states
Community property titled as joint tenancy instead of CPWROS
Loses the double step-up in basis — only the decedent's half gets a basis reset; CPWROS provides both probate avoidance AND the full double step-up
Holographic will with typed material provisions
May be invalid as a holographic will — material provisions must be in the testator's handwriting
No will, married with children (separate property)
Surviving spouse receives only one-half of separate property — children receive the other half; community property goes entirely to spouse
Separate property commingled with community property
Property may be presumed community — without documentation showing separate character, the property classification may shift, affecting inheritance
No advance directive before incapacity
Medical decisions fall to a statutory surrogate hierarchy; Idaho separates the living will from the healthcare POA
Electronic will not meeting Idaho's specific requirements
Invalid — electronic wills have specific requirements under Idaho Code § 15-2-1105; not all digital documents qualify
If This Is Your Situation
Married with children (intestacy — community property)
Surviving spouse receives ALL of the decedent's community property half
Married with children (intestacy — separate property)
Surviving spouse receives ONE-HALF of separate property; children share the other half
Married, no children, surviving parents (intestacy — separate property)
Surviving spouse receives ONE-HALF of separate property; parents receive the other half
Married, no children, no parents (intestacy)
Surviving spouse inherits the entire estate — both community and separate property
Want to avoid probate for real estate
Must use a revocable living trust, CPWROS (for married couples), or joint tenancy — Idaho does NOT allow TOD deeds for real property
Estate under $100,000 in personal property
Small estate affidavit available — 30-day waiting period; presented directly to asset holders; community property affidavit also available for surviving spouse
Want maximum tax benefit on community property
Use CPWROS — combines automatic probate avoidance with the double step-up in basis; both halves of CP reset to fair market value at first death

How Idaho Actually Works
Idaho adopted the Uniform Probate Code (modified), making its probate system generally efficient. Informal probate without a hearing is the default for uncontested estates, holographic wills are recognized, interested witnesses don't invalidate wills, and the state recently joined the small group allowing electronic wills.
As a community property state, Idaho provides one of the most powerful tax advantages available: the double step-up in basis. When one spouse dies, both halves of community property receive a new basis equal to fair market value — not just the decedent's half. For a couple who bought a home for $150,000 that is now worth $500,000, this resets the surviving spouse's basis to $500,000. Sell the next day? Zero capital gains tax. This benefit is only available if the property is titled as community property or CPWROS — not joint tenancy.
But Idaho has a critical gap that makes it different from every neighboring state: it does not allow transfer-on-death deeds for real property. Washington, Oregon, Montana, and Nevada all have TOD deed statutes. Idaho doesn't. This means any real estate not held in a trust, CPWROS, or joint tenancy must go through probate. For families who own a home, ranch, or farmland, a revocable living trust is essentially mandatory if they want to avoid probate.
CPWROS (community property with right of survivorship) is an underused alternative for married couples. It provides automatic transfer to the surviving spouse at death (no probate), preserves the double step-up in basis (because it's still community property), and is simpler than a trust. For couples whose primary goal is 'everything goes to my spouse,' CPWROS delivers that without court involvement. The state updated its homestead exemption in July 2025 to $175,000 per person ($350,000 for married couples), providing additional creditor protection.
Without a Will: How Idaho Distributes Your Estate
This is where Idaho gets complicated — and where the community property distinction matters most. Idaho is a community property state. Assets acquired during marriage are generally owned equally by both spouses. Assets owned before marriage, or received as a gift or inheritance during marriage, are separate property. When someone dies without a will, these two categories follow different rules.
Idaho's intestacy rules follow the community/separate property distinction. Community property passes entirely to the surviving spouse — straightforward. But separate property is split differently: the spouse receives only half when there are children or surviving parents. If there are no children and no parents, the spouse inherits everything.
This means families with significant separate property — inherited land, pre-marriage assets, or gifts — need to plan carefully. Without a will or trust, half of that separate property passes to children or parents, not the surviving spouse.
Married with children (same marriage)
Community property: surviving spouse receives ALL of the decedent's community property half. Separate property: surviving spouse receives ONE-HALF; children share the other half.
Married with children from a prior relationship
Same as above — community property all to spouse; separate property 1/2 to spouse, 1/2 to children.
Married, no children
If surviving parents: community property all to spouse; separate property 1/2 to spouse, 1/2 to parents. If no parents: spouse inherits the entire estate.
Single with children
Children inherit the entire estate equally by representation.
Single, no children
Parents inherit equally. If no parents, siblings and their descendants by representation. Then grandparents (split paternal/maternal).
Survival period: 120 hours (5 days)
Idaho's intestacy for community property is straightforward — all to the surviving spouse. But separate property follows a different rule: the spouse gets half if there are children OR surviving parents. This means a surviving spouse with children from the current marriage still loses half of the decedent's separate property. Half-blood relatives inherit equally. Posthumous relatives conceived within 10 months of death can inherit. The CPWROS option eliminates the need for probate entirely for community property.
Wills in Idaho
What makes a will valid
A written will signed by the testator (or by another person at the testator's direction and in the testator's presence) and signed by at least two witnesses. Alternatively: a holographic will with signature and material provisions in the testator's handwriting. Also: an electronic will meeting Idaho Code § 15-2-1105 requirements.
What people think
That a TOD deed can be used to avoid probate for real estate, or that all community property automatically avoids probate.
What actually happens
Idaho does NOT allow TOD deeds for real property. Standard community property still requires probate for the decedent's half — only CPWROS bypasses probate automatically. This is the most common gap in Idaho estate planning. The state offers three valid will forms (formal, holographic, electronic) and interested witnesses do not invalidate the will.
Common failure
Assuming a TOD deed is available for the family home (it isn't in Idaho). Also: titling community property as joint tenancy, which loses the double step-up in basis. And holographic wills with typed material provisions.
When a trust is better
When you own real property (since Idaho has no TOD deeds), when you want to avoid probate and maintain the double step-up, when managing distributions to minors, or for incapacity planning. A trust is more essential in Idaho than in most other states because of the TOD deed gap.
Execution checklist
- Ensure the testator is 18+ and of sound mind
- Choose the form: formal (witnessed), holographic (handwritten), or electronic (digital)
- For formal wills: sign and have two witnesses sign after observing the signing or acknowledgment
- For holographic wills: signature and material provisions in your handwriting
- For electronic wills: comply with Idaho Code § 15-2-1105 requirements
- Execute a self-proving affidavit (notarized) — strongly recommended
- Review community/separate property titling — consider CPWROS for married couples
- Address real property in a trust since Idaho has no TOD deeds
Power of Attorney in Idaho
What it does
Grants authority to a named agent to manage financial and legal affairs on behalf of the principal. Healthcare decisions require a separate directive.
Key rule
Idaho follows the Uniform Power of Attorney Act. The POA must include specific durability language.
Real-world friction
Financial institutions may reject POAs they consider outdated. Using Idaho's statutory form reduces rejection risk.
Common mistake
Assuming a financial POA covers healthcare decisions. Idaho separates these — you need a durable financial POA, a living will, AND a healthcare POA.
Healthcare Directive in Idaho
What it covers
Your preferences for life-sustaining treatment (living will under the Natural Death Act) and the designation of a healthcare agent for all medical decisions during incapacity (healthcare POA).
What's different
Idaho separates the living will from the healthcare POA — they are distinct documents serving different purposes. The living will covers only terminal conditions; the healthcare POA covers broader medical decisions.
Execution requirements
Living will: two witnesses required. Healthcare POA: written and signed.
Common misunderstanding
Thinking a living will covers all medical decisions. It doesn't — it only applies to terminal or irreversible conditions. The healthcare POA provides authority for all medical decisions during incapacity.
Probate in Idaho
When required
When assets are held solely in the decedent's name without CPWROS, joint tenancy, beneficiary designation, or trust — and the estate exceeds $100,000 in personal property or includes any real property not otherwise exempt.
What makes Idaho different
Idaho's most distinctive probate feature is the absence of TOD deeds for real property. Every neighboring state — Washington, Oregon, Montana, Nevada — allows them. Idaho doesn't. This means a trust or CPWROS is required for any family wanting to keep real estate out of probate. The state does offer a community property affidavit for surviving spouses and a $100,000 small estate affidavit for personal property. Electronic wills are recognized. The UPC-based informal probate process is efficient when uncontested.
Probate paths
Small estate affidavit· Weeks
For personal property at $100,000 or less. 30-day waiting period. Presented directly to asset holders. Does NOT cover real estate.
Community property affidavit· Weeks
For surviving spouse to claim community property without full probate.
Informal probate· 6–12 months
UPC-based streamlined process. No hearing when uncontested. 4-month creditor claim period.
Formal probate· 12+ months
Court-supervised with hearings. Required when contested.
What people get wrong
Assuming TOD deeds are available for real property in Idaho (they aren't — this is a critical gap). Also: titling community property as joint tenancy instead of CPWROS, which sacrifices the double step-up in basis. And assuming all community property avoids probate — only CPWROS does; standard community property requires probate for the decedent's half.
Trusts in Idaho
When a trust is useful
Essential for any Idaho family owning real property who wants to avoid probate — since TOD deeds are not available. Also useful for managing distributions to minors, maintaining privacy, incapacity planning, or holding property in multiple states. A trust is more important in Idaho than in most states because of the TOD deed gap.
When a trust is unnecessary
Married couples whose only real property is held as CPWROS (which avoids probate and preserves the double step-up). Estates consisting entirely of personal property under $100,000 (which can use the small estate affidavit).
Key mistake
Not creating a trust when you own real property. Idaho's lack of TOD deeds means any real estate not in a trust, CPWROS, or joint tenancy MUST go through probate. This is the single most common planning failure in Idaho.
Common Mistakes
Assuming TOD deeds are available for real property
Idaho does NOT allow transfer-on-death deeds for real estate — unlike Washington, Oregon, Montana, and Nevada. A trust, CPWROS, or joint tenancy is the only way to keep real property out of probate.
Titling community property as joint tenancy
Joint tenancy avoids probate but provides only a single step-up in basis. CPWROS provides BOTH probate avoidance AND the double step-up. For community property, CPWROS is almost always the better choice.
Not creating a trust when owning real property
Because Idaho has no TOD deeds, a trust is the primary tool for avoiding probate on real estate. Without one, the family home, ranch, or land must go through probate regardless of value.
Assuming all community property avoids probate
Only community property with right of survivorship (CPWROS) bypasses probate automatically. Standard community property still requires probate for the decedent's half.
Holographic will with typed material provisions
Idaho requires material provisions to be in the testator's handwriting for a holographic will. Typed dispositive language may invalidate the document.
Not distinguishing community from separate property
Intestacy gives the spouse all community property but only half of separate property when children or parents survive. Without clear documentation, property may be mischaracterized.
Not using CPWROS for the family home
CPWROS is one of the most underused tools in Idaho estate planning. It provides automatic transfer to the surviving spouse at death, double step-up in basis, and no probate — all without the complexity of a trust.
What Most People Actually Need
Most people don't need a trust. They need a valid will, a durable power of attorney, and a healthcare directive — executed correctly under Idaho law. The most common mistakes are ones of execution, not planning.
Check your situation →Frequently Asked Questions
Does Idaho have an estate tax or inheritance tax?›
No. Idaho does not impose a state estate tax or inheritance tax. Only the federal estate tax applies, which currently affects estates exceeding $15 million (2026 threshold).
Does Idaho allow transfer-on-death deeds for real property?›
No. Idaho is one of the few western states that does NOT allow TOD deeds for real estate. Washington, Oregon, Montana, and Nevada all permit them. In Idaho, a trust, CPWROS, or joint tenancy is required to avoid probate for real property.
What is community property with right of survivorship (CPWROS)?›
CPWROS is a form of property titling available to married couples that combines community property benefits (double step-up in basis) with automatic transfer to the surviving spouse at death (no probate needed). It's available for both real and personal property under Idaho Code §§ 15-6-401 to 15-6-402.
Does Idaho recognize electronic wills?›
Yes. Idaho is one of a small number of states that allows electronic wills — wills created, signed, and witnessed in digital format under Idaho Code § 15-2-1105. The requirements are specific and the concept is still relatively new.
What happens if you die without a will in Idaho?›
Community property goes entirely to the surviving spouse. Separate property: the spouse receives half if there are children or surviving parents; the spouse receives everything if there are no children and no parents. The 120-hour survivorship period applies.
What is Idaho's small estate threshold?›
$100,000 for personal property. The small estate affidavit allows simplified transfer with a 30-day waiting period. It does NOT cover real property. A community property affidavit is also available for surviving spouses to claim community property without full probate.
Are holographic (handwritten) wills valid in Idaho?›
Yes. A holographic will is valid if the signature and material provisions are in the testator's handwriting. No witnesses are required. However, holographic wills are more difficult to prove in probate and are more susceptible to challenges.
What is the double step-up in basis?›
When one spouse dies, both halves of community property — including the surviving spouse's half — receive a new tax basis equal to fair market value. This can eliminate capital gains tax on the sale of appreciated assets. The benefit is only available in community property states and only if the property is properly titled as community property (not joint tenancy).
