Oregon Estate Planning 2026: The $1M Exemption, No Portability, and What Oregon Families Must Know

Oregon imposes its own estate tax starting at $1,000,000 — the lowest threshold in the country. The federal exemption is $15,000,000, so most national estate planning coverage ignores this entirely. That's a problem for Oregon families: a Portland couple with a home worth $750,000, two IRAs, and a rental property can easily have an estate over $1M and owe $100,000 or more in Oregon estate tax that their attorney never mentioned. There's no portability — the first spouse to die loses their $1M exemption unless it was planned into a bypass trust. And yet Oregon has no state gift tax, making annual gifting one of the most tax-efficient strategies available. This guide explains what Oregon residents actually need to know in 2026.

How Oregon estate tax works in 2026

Oregon imputes its own estate tax under ORS Chapter 118, separate from the federal system. The tax applies to the Oregon taxable estate — generally the gross estate (all property the decedent owned or had power over at death) less allowable Oregon deductions. The first $1,000,000 is effectively exempt: the rate table starts at zero for estates below that threshold.

Above $1M, the tax is graduated, starting at 10% on the first taxable bracket and rising to 16% on amounts over $9.5M. The rates are marginal — only the excess above each bracket threshold is taxed at the higher rate. A $3M estate pays 10% on the first bracket, 10.25% on the second, and 10.5% on the remainder — not 10.5% on everything.

Source: ORS 118.010. Oregon taxable estate = federal taxable estate (as modified under Oregon law). The marital deduction and charitable deduction generally reduce the taxable estate as under federal rules. Actual liability is computed on Form OR-706.

What Oregon families actually owe — illustrative amounts

The table below shows approximate Oregon estate tax for common estate sizes, assuming the gross estate passes entirely through the taxable estate (no marital deduction, no charitable deduction, no bypass trust). Actual liability depends on the full OR-706 computation and allowable deductions.²

The portability problem — the biggest planning gap for Oregon married couples

Oregon does not allow portability. When the first spouse dies, any unused portion of their $1M exemption is permanently lost — it cannot be transferred to the surviving spouse the way the federal DSUE can. This makes the bypass trust — also called a credit shelter trust or family trust — one of the most important estate planning tools available to Oregon married couples.³

The cost of not planning for Oregon couples

Consider a married couple with $3M in combined assets. Both spouses die over the next 20 years.

Without a bypass trust:

• Spouse 1 dies. All assets pass to Spouse 2 under the marital deduction — zero Oregon tax at the first death. But Spouse 1's $1M exemption is permanently lost.
• Spouse 2 dies with $3M (estate grew over time). Oregon taxable estate: $3M. Tax: approximately $205,000.

With a bypass trust:

• Spouse 1's estate plan includes a bypass trust funded with $1M of individually-titled assets at death.
• Spouse 1's $1M exemption is fully used by the bypass trust. The surviving spouse is the income beneficiary and can access principal for health, education, maintenance, and support (HEMS).
• Spouse 2 dies with $2M in their individual estate (the other $1M is in the bypass trust, outside the survivor's taxable estate). Spouse 2 has their own $1M Oregon exemption. Oregon taxable estate on $2M: $1M taxable → approximately $101,250.
• Tax savings from the bypass trust: approximately $103,750 on a $3M estate.

At $5M combined, the planning difference grows: without a bypass trust, the second spouse faces approximately $425,000 in Oregon estate tax. With bypass trusts for both spouses (if assets are equalized), each uses their $1M exemption and the taxable estate at the second death is $3M — approximately $205,000. Savings: $220,000, before accounting for any annual gifting or irrevocable trust strategies.

Asset titling is prerequisite — the bypass trust only works if assets are in the right name

A bypass trust in a will or revocable trust does nothing unless assets are individually titled in the name of the spouse who dies first. Joint tenancy with right of survivorship (JTWROS) passes automatically to the survivor — bypassing the trust. Couples with everything in joint accounts need to retitle a portion into individual names to make the bypass trust work. This is one of the most common, most costly Oregon estate planning mistakes.

Oregon's no-gift-tax advantage: annual gifting permanently reduces your estate

Oregon has no state gift tax, and gifts made during life do not come back into the Oregon gross estate — there is no lookback period under Oregon law.³ This makes lifetime gifting one of the most tax-efficient estate planning tools available to Oregon residents.

The federal annual exclusion is $19,000 per donor per recipient in 2026 ($38,000 for married couples who gift-split).³ Every dollar given away under the annual exclusion permanently exits the Oregon taxable estate — with no Oregon tax, no federal gift tax, and no Oregon gross estate inclusion at death. A couple with two adult children can remove $76,000 per year from their combined Oregon estate. Over 10 years that is $760,000 permanently outside Oregon's reach — and the assets' future appreciation is removed as well.

Annual gifting impact table (Oregon couple, 2 children, $38K/year/child)

*Assumes principal only, 10% marginal rate bracket. Actual savings higher when future appreciation on gifted assets is also removed from the taxable estate.

Direct tuition payments and direct medical expense payments — made directly to the institution or provider — are unlimited gifts that never reduce the federal lifetime exemption and have no Oregon estate tax consequence. For grandparents with college-age grandchildren, this is additional gifting capacity on top of the $19K annual exclusion.

Oregon estate planning for larger estates ($3M–$15M+)

For Oregon families with $3M to $15M in net worth, the bypass trust and annual gifting are the foundation, but irrevocable trust strategies significantly reduce Oregon estate tax on amounts the bypass trust and exemption don't shelter.

Key strategies for Oregon HNW families

Spousal Lifetime Access Trust (SLAT). A SLAT transfers assets out of the grantor's estate while giving the trustee discretion to benefit the spouse. The grantor uses their federal lifetime exemption ($15M in 2026) to fund the SLAT — the contribution is a gift for federal purposes, removing the assets and all future appreciation from both the federal and Oregon taxable estates. For Oregon families with estates well above $2M, SLATs can shelter millions from both Oregon and federal estate tax simultaneously. See SLAT guide.

GRAT (Grantor Retained Annuity Trust). A zeroed-out GRAT transfers expected appreciation above the §7520 hurdle rate out of the estate at minimal gift-tax cost — no federal lifetime exemption consumed if zeroed out. At a §7520 rate of 5.00% (May/June 2026), any asset that outperforms 5% annually transfers the excess to heirs tax-free at both the Oregon and federal level. Best used for appreciated real estate, closely-held business interests, or publicly-traded stock expected to rise. See GRAT calculator.

Intentionally Defective Grantor Trust (IDGT) installment sale. Transfer a business interest or real estate portfolio to an IDGT via installment note at the applicable AFR (mid-term AFR ~4.08%, June 2026). Future appreciation above the note's interest rate passes to the trust completely outside the grantor's Oregon and federal taxable estate. See IDGT guide and calculator.

Family Limited Partnership / Family LLC. Consolidating family assets into an FLP or LLC and then gifting minority interests (with valuation discounts of 20–35% for lack of control and marketability) can significantly reduce the Oregon taxable value transferred. Oregon applies no state-level restriction on FLP valuation discounts for estate tax purposes. See FLP guide and valuation discount calculator.

Charitable Remainder Trust (CRT/CRUT). Converts appreciated assets — farmland, timber, business interests, appreciated stock — into a lifetime income stream while removing the asset from the Oregon taxable estate and generating a federal charitable deduction. Oregon-basis farmland held for decades that would trigger substantial capital gains at sale can often be contributed to a CRUT, with capital gains deferred inside the trust and converted to distributed income. See CRT guide.

Oregon natural resource exemption — farm, forestry, and fishing

Oregon provides an estate tax exemption for qualifying natural resource property — farmland, forestland, and commercial fishing properties — under ORS 118.140.⁴ The exemption allows qualifying businesses up to $15,000,000 in natural resource property to pass free of Oregon estate tax, provided the property meets use, ownership, and continuation requirements.

This is a significant planning tool for the Willamette Valley wine and farming community, the Coast Range and Cascades timber landowners, and commercial fishing families. The requirements are detailed and require careful structuring — a qualifying small family business can use the exemption in addition to the $1M individual exemption, potentially sheltering large estates from most or all Oregon estate tax. This exemption does not apply to rental real estate, vacation properties, or investment land not actively used in a natural resource business.

Oregon vs. neighboring states: the relocation calculus

Oregon's $1M exemption and 10–16% rate structure make it one of the most estate-tax-burdensome states in the West. Neighboring states vary dramatically:

Moving from Oregon to Idaho, Nevada, or Arizona eliminates Oregon estate tax exposure on non-Oregon-situs property — and all three states also have no income tax on capital gains the way Oregon does. The key planning consideration: Oregon real estate remains subject to Oregon estate tax even if the owner moves away (situs taxation). A Lake Oswego home still triggers Oregon estate tax in the owner's estate even if they've relocated to Boise or Las Vegas. See California and Washington estate planning for comparison of the full West Coast picture.

Establishing domicile in a new state requires more than owning property there. The key factors: changing voter registration, updating driver's license, filing a Declaration of Domicile if the new state offers one (Florida does; Idaho and Nevada do not), spending more than 183 days/year in the new state, updating estate planning documents to reference the new state's laws, and changing all financial account addresses. Oregon may audit domicile claims made within 2 years of significant estate tax savings.

2026 Oregon estate tax repeal ballot measure

The Oregon Repeal Estate Tax Initiative qualified for the November 2026 ballot.⁵ If passed by voters, Oregon's estate tax would be eliminated entirely — repealing ORS Chapter 118 for future decedents. The measure would have no effect on estates of decedents who died before its effective date.

Two prior Oregon efforts to reform the estate tax — HB2301 (which would have raised the exemption to $7M and set a flat 7% rate) and SB405 (which would have conformed Oregon's exemption to the federal level) — both failed in committee during the 2025 legislative session. The ballot initiative is the remaining avenue for change in the near term.

Planning implication: Do not defer Oregon estate planning based on the possibility of repeal. If the initiative fails or is delayed, families who waited will have lost another year of gifting and trust formation. If it passes, the bypass trust and irrevocable trust structures already in place will still have transferred appreciated assets out of the estate — the planning is not wasted. Act under current law; benefit from any future change.

Portland/Willamette Valley case study: Mike and Linda, age 70 and 68

Mike and Linda live in Lake Oswego. Their combined assets:

• Primary residence (JTWROS): $900,000
• Rental property (Mike's name): $450,000 (low basis: $80,000)
• Brokerage account (JTWROS): $650,000
• Mike's rollover IRA: $500,000
• Linda's IRA: $400,000
• Total gross estate: $2,900,000

Without planning — Mike dies first:

• All joint assets pass to Linda via right of survivorship. Mike's IRA rolls over to Linda. Oregon marital deduction = $0 Oregon tax at first death.
• Mike's $1M Oregon exemption is permanently lost. Linda has $2.9M.
• Linda dies with $3.2M (modest growth). Oregon taxable estate: $2.2M after her $1M exemption. Tax: approximately $170,000.
• Plus: inherited IRAs are IRD — no step-up in basis. Children pay ordinary income tax on every dollar withdrawn. Federal estate tax: $0 (below $15M).

With planning:

• Retitle the rental property to Mike's individual name (already done). Retitle $100,000 of brokerage into Mike's individual name only.
• Credit shelter trust in Mike's revocable trust: At Mike's death, $1M funds the bypass trust (rental property + individual brokerage). Mike's Oregon exemption is fully used. Linda is the income beneficiary; principal accessible for HEMS.
• Annual gifting: $38,000/year ($19K each) to their daughter. Over 10 years, $380,000 permanently outside both Oregon and federal estates — along with all future appreciation.
• Linda's estate at death: $1.9M individual (gross estate grew, less $380K gifted) + $1M bypass trust (outside her estate). Linda's $1M exemption → $900K taxable. Oregon tax: approximately $90,000 — down from $170,000 without planning.
• Net savings from bypass trust + gifting: Approximately $80,000 in Oregon estate tax, before accounting for capital gains planning on the rental property and IRA income tax strategies.

For Mike and Linda, who might pay $3,000–$7,000 in legal fees to establish the bypass trust and retitle assets, the expected Oregon estate tax savings of $80,000+ represents a 10–25× return on that investment.

7 Oregon estate planning mistakes that cost families the most

1. Titling everything as JTWROS. Joint accounts bypass the decedent's trust — making bypass trust funding impossible at the first death and wasting the first spouse's $1M Oregon exemption permanently.
2. Assuming federal rules apply. Oregon does not have portability. An advisor or attorney who says "you're fine — you're under the $15M federal limit" is thinking federally only. Families with $2M–$6M estates often have significant Oregon exposure that federal planning analysis never surfaces.
3. Waiting on the repeal ballot measure. The 2025 legislative reforms both failed. The 2026 initiative may or may not pass. Families who defer planning incur another year of appreciation inside the estate and another year without annual gifts permanently exiting the estate.
4. Not retitling assets to fund the bypass trust. A bypass trust in a revocable trust or will must be funded to work. Assets that remain in JTWROS or are beneficiary-designated to the surviving spouse bypass the trust and waste the exemption.
5. Holding highly appreciated Oregon real estate inside the estate. Holding until death preserves the federal step-up in basis — but also keeps the appreciation inside the Oregon taxable estate. For families where real estate appreciation has pushed the estate well beyond $2M, GRAT or IDGT structures can shift future appreciation outside the estate while leaving current basis-anchored decisions intact. See real estate estate planning strategies.
6. Neglecting the IRA income tax trap. IRAs don't get a step-up in basis at death and are subject to ordinary income tax when inherited. A $500K IRA is worth only $315K–$370K after-tax to heirs in the top bracket. Roth conversions during life reduce the Oregon taxable estate (IRAs are includable) and convert pre-tax dollars to tax-free at potentially lower rates. See IRA estate planning.
7. Ignoring Oregon situs property after moving. Oregon real estate in an estate is subject to Oregon estate tax even if the decedent was domiciled in another state at death. Families who move to Idaho, Nevada, or Washington but retain an Oregon vacation home or rental property still owe Oregon estate tax on that property. Converting real property to an LLC interest may convert it to intangible personal property that follows the owner's new domicile — but this requires careful legal and tax analysis.
