Oregon Estate Planning: The Complete Guide to Wills, Trusts, and Tax Traps

Oregon has estate planning rules that don't exist in most other states. A $1 million estate tax threshold that hasn't been adjusted since 2012. No spousal portability — meaning married couples can't share exemptions. Medicaid estate recovery that reaches beyond probate into trusts, joint accounts, and Transfer-on-Death Deeds. And the nation's first Death with Dignity Act alongside the POLST system Oregon pioneered in 1991.

These aren't edge cases. They affect middle-class homeowners, retirees, and anyone relocating from a community property state like Washington or California.

The Five Documents Every Oregon Resident Needs

1. Last Will and Testament

Oregon requires a written will, signed by the testator, witnessed by two competent adults (ORS 112.235). Electronic wills are explicitly invalid. Holographic (handwritten, unwitnessed) wills are not recognized if created in Oregon.

A self-proving affidavit — signed before a notary public alongside the witnesses — eliminates the need to track down witnesses during probate. It's optional but strongly recommended.

Parents of minor children should use the will to nominate a guardian. Without a nomination, the court decides based on statutory preferences, and family disagreements can lead to costly litigation.

2. Durable Power of Attorney

A durable financial power of attorney lets your designated agent manage your finances if you become incapacitated. Without one, your family may need a court-appointed conservatorship — a process that costs $3,000 to $10,000 and strips your legal rights.

Oregon also recognizes a durable healthcare power of attorney, though most residents use the statutory advance directive form instead (which includes health care representative appointment).

3. Oregon Advance Directive

Oregon's statutory advance directive form was revised following Senate Bill 199. It lets you appoint a health care representative and document your treatment preferences — including decisions about life-sustaining treatment, artificial nutrition, and pain management.

The form requires either two witnesses or notarization. Your health care representative can make decisions on your behalf when you can no longer communicate your own wishes.

4. POLST Form (If Applicable)

Oregon created the Portable Orders for Life-Sustaining Treatment (POLST) program in 1991. Unlike an advance directive — which expresses preferences — a POLST is a medical order signed by your physician that emergency responders must follow.

POLST forms are appropriate for people with serious illnesses, advanced frailty, or anyone whose health status means they might not survive CPR or aggressive treatment. They are not general planning documents for healthy adults.

5. Beneficiary Designation Review

This isn't a single document — it's a review of every account that passes by beneficiary designation: life insurance, IRAs, 401(k)s, POD bank accounts, TOD investment accounts, and Transfer-on-Death Deeds.

Oregon does not automatically revoke an ex-spouse's beneficiary designation after divorce. If your IRA still names your ex-spouse, they receive the account — regardless of what your will says. Coordinating these designations with your will is the single most important step in Oregon estate planning.

Oregon's $1 Million Estate Tax Trap

The federal estate tax exemption is approximately $13.99 million per person (2025). Oregon's exemption is $1 million — fixed since 2012, not indexed to inflation.

With Portland, Bend, and Eugene home values appreciating rapidly, a family with a $600,000 home, $300,000 in retirement accounts, and a $200,000 life insurance policy has a $1.1 million estate and owes Oregon estate tax.

The graduated rate structure runs from 10% to 16%. An estate worth $1.5 million owes approximately $50,000. At $2 million, the bill is approximately $101,250.

The Portability Problem

Federal law lets a surviving spouse inherit the deceased spouse's unused exemption. Oregon does not. Each spouse gets exactly one $1 million exemption, and it disappears at death if not used.

A married couple with $2 million in combined assets who uses simple wills leaving everything to the surviving spouse wastes the first spouse's entire exemption. A credit shelter trust preserves both exemptions, potentially saving $101,250 in estate tax.

Probate in Oregon: Two Tracks

Simple Estate Affidavit

Estates valued at $275,000 or less — with no more than $200,000 in real property and $75,000 in personal property — qualify for this simplified process. Filing fee: $124. Must wait at least 30 days after death before filing.

Formal Probate

Estates exceeding these thresholds require court-supervised administration. Progressive filing fees run from $278 to $1,176. The personal representative must publish a newspaper notice for three consecutive weeks and file an asset inventory within 90 days. Creditors have four months from first publication to present claims.

Community Property and Oregon Relocators

Oregon is a common-law property state, not a community property state. Couples relocating from Washington, California, Idaho, or other community property states face a specific risk: losing the double step-up in basis on community property assets.

Under federal law, community property receives a full step-up in basis on both halves when one spouse dies — not just the deceased spouse's half. If community property is commingled into a common-law state like Oregon, that double step-up can be lost, exposing the surviving spouse to substantial capital gains taxes on appreciated assets.

Oregon's Uniform Disposition of Community Property Rights at Death Act (ORS 112.705 to 112.775) provides some protection, but proactive planning — including a community property trust agreement — is essential for relocating families.

Medicaid and Oregon's Augmented Estate Recovery

Oregon's Medicaid estate recovery reaches the "augmented estate" under ORS 416.350. This includes assets passing outside probate: revocable trust assets, joint tenancies, and Transfer-on-Death Deeds. Basic probate-avoidance strategies do not protect against Medicaid recovery.

The income cap for Medicaid long-term care eligibility is $2,982 per month (2026). Applicants over this limit must establish an income cap trust (Miller Trust) to qualify. The asset limit is $2,000 — and Oregon counts retirement accounts (IRAs, 401(k)s) as available assets.

Recovery is deferred while a surviving spouse, minor child, or blind/disabled child of any age survives. But once that protection lifts, the Department of Human Services pursues recovery aggressively.

Next Steps

Oregon's estate planning requirements are more demanding than most states, but the core documents — will, power of attorney, advance directive, and coordinated beneficiary designations — handle the majority of situations.

The Oregon Basic Estate Planning Kit provides Oregon-specific checklists, worksheets, and decision guides for each of these documents, including the credit shelter trust analysis for couples approaching the $1 million threshold.
