Live in Vancouver, Own Property in Oregon? The Oregon Estate Tax and Probate Trap

If you live in Vancouver or anywhere in Clark County and own real estate on the Oregon side of the river, Oregon’s estate tax can reach your estate — and Oregon measures its $1 million threshold against everything you own, not just the Oregon property. Your family may also face a second probate, in Oregon, to clear title.

Picture a Vancouver couple who came to the river for the obvious reasons. He kept his job at a hospital in Portland. She ran her business out of a leased space off Macadam. They bought in Felida, raised two kids, and enjoyed what the Washington side of the Columbia offers families like them: a higher estate tax exemption and a probate system most lawyers in the country would envy.

They kept one thing from the old life. A rental duplex in Southeast Portland. Bought in 2004 for $180,000. Worth about $600,000 now. Good tenants, no trouble, and the cash flow covered a car payment and then some.

He died first, and everything passed to her. When she died, the Washington numbers worked exactly the way the family expected. Her estate ran a little over $4,000,000. Washington’s exclusion covered the first $3,000,000. The family filed a Washington return, paid what Washington asked, and thought the state tax chapter was closed.

Then the family’s accountant asked about the duplex. An Oregon estate tax return was due.

Nobody had told them that owning a duplex in Multnomah County put them inside Oregon’s estate tax system — and that Oregon measures the entry threshold against everything the decedent owned, not against the duplex. The duplex was worth $600,000. Oregon’s threshold is $1,000,000. They assumed they were nowhere close.

They were not close. They were in.

That family is a composite. The statutes and the math below are real.

Do I need a living trust if I live in Vancouver, Washington?

Probably less urgently than your cousin in Clackamas County — and I would rather tell you that than sell you something you do not need.

Washington gives its families something Oregon does not. Under RCW 11.68.011, the court shall grant nonintervention powers to a personal representative who petitions for them, as long as the estate is solvent and one of the statute’s three conditions is met — the most common being that the person asking was named as personal representative in the will the court admitted. The statute’s own heading says it plainly: settlement without court intervention.

In practice, a Washington personal representative with nonintervention powers administers the estate, pays the debts, sells what needs selling, and distributes to the beneficiaries without going back to a judge for permission at each step.

That is a real difference, and I will not pretend otherwise. In Oregon, the personal representative files an inventory with the court within 90 days under ORS 113.165, and the court supervises the administration. In Oregon, supervision is the default, and families use a trust to avoid it.

In Washington, the lack of supervision is closer to the default, and a well-drafted will that asks for nonintervention powers handles a great many Clark County estates without drama.

So here is the honest answer. If everything you own sits in Washington, your family is intact, your beneficiaries are adults who get along, and your estate is under the Washington exclusion, a will with nonintervention powers may be enough. A revocable living trust earns its keep in Vancouver for four specific reasons, and none of them is “probate is a nightmare here,” because here it often is not.

It earns its keep when you own real property in another state — which, in this county, usually means Oregon. It earns its keep when you have a blended family and the Washington intestacy and community property defaults would land somewhere you never intended. It earns its keep when the estate is large enough that the first death has to be structured rather than simply survived. And it earns its keep when someone in the family needs a share managed rather than handed over — a minor, a beneficiary with a disability, a child in the middle of a divorce.

One sentence before going further: a living trust is not asset protection.

How much can I leave before Washington estate tax applies?

For a death on or after July 1, 2026, the Washington exclusion is $3,000,000 under RCW 83.100.020(1)(a). For a death between January 1 and June 30, 2026, it was $3,076,000. For deaths from July 1, 2025 through the end of 2025, it was $3,000,000, and before that — from mid-2018 through June 30, 2025 — it sat at $2,193,000.

Two things about that number deserve your attention.

The first is that you should not count on it going up. The statute calls for an annual inflation adjustment starting in 2027, tied to a consumer price index it identifies as the Seattle-Tacoma-Bremerton index. The Washington Department of Revenue’s estate tax page, however, says the amount “is not set to increase going forward due to an expired CPI in the statute.” Plan on $3,000,000 and treat any future increase as a pleasant surprise rather than a line in your model.

The second is that the rate schedule moved twice in twelve months, and the direction of the second move is good news. For deaths between July 1, 2025 and June 30, 2026, the table in RCW 83.100.040(2)(a)(ii) ran the top bracket up to 35%. For deaths on or after July 1, 2026, table (iii) applies — the same rates as the original table, topping out at 20% on the portion of a Washington taxable estate above $9,000,000. The brackets begin at 10% on the first $1,000,000 above the exclusion and climb from there. (For the full Washington picture, see my Vancouver and Clark County estate planning page.)

The filing trigger is measured on everything. Washington’s Department of Revenue says a return is required when the decedent’s gross estate, “wherever the assets are located,” is over the filing threshold. Your Idaho cabin and your Arizona condo count toward whether you file, even though the tax is apportioned away from them.

That apportionment works like this. Under RCW 83.100.040(2)(b), if any property in the estate sits outside Washington, the tax is the computed amount multiplied by a fraction — the value of property located in Washington over the value of the gross estate. And under RCW 83.100.040(1), intangible property owned by a resident is treated as located in Washington. Your brokerage account, your retirement accounts, your business interests held as intangibles — for Washington’s purposes, those are here.

Does Oregon estate tax apply if I live in Washington?

Yes, if you own Oregon real property or Oregon tangible personal property. This is the trap, and it is the reason this article exists.

ORS 118.010(2)(b) imposes the Oregon estate tax on the estate of a nonresident decedent whose estate includes an interest in Oregon real property or Oregon tangible personal property. Living in Vancouver does not take you out of it. Dying as a Washington domiciliary does not take you out of it. Owning the duplex is what puts you in.

Now the part that catches people. The Oregon filing threshold is in ORS 118.160(1)(c): a return is not required “unless the value of the gross estate is $1 million or more.” That statute does not say Oregon gross estate. And ORS 118.005(6) gives “gross estate” the meaning in section 2031 of the Internal Revenue Code — the federal gross estate, which is everything you own, everywhere.

So the threshold is not measured against your Portland duplex. It is measured against your house in Felida, your retirement accounts, your business, your life insurance if you own the policy, and the duplex. A Clark County estate of $4,000,000 with a $600,000 rental across the river is over Oregon’s threshold by a factor of four, and the $600,000 figure that felt safely under $1,000,000 never enters that calculation.

What Oregon then taxes is only the Oregon slice — but it computes the rate as if the whole estate were Oregon’s. ORS 118.010(6) says the tax is the amount determined under the subsection (4) rate table, multiplied by a fraction whose numerator is the value of the decedent’s Oregon real property and Oregon tangible personal property, and whose denominator is the total gross estate (each less any Oregon natural resource exemption).

That sequence matters. The rate is set by the size of your whole estate. The bill is then scaled down to the Oregon share. A small Oregon rental inside a large estate gets taxed at the rate that large estate earns. (The full Oregon rate table is in my article on Oregon estate tax rates.)

Here is the math for the family above. Assume a $4,000,000 gross estate, a $600,000 Portland duplex, everything else in Washington, a death on or after July 1, 2026, and no deductions (including the federal deduction for state estate taxes, which I leave out to keep the example clean).

State estate tax$85,000$46,875

Total state estate tax: $131,875.

Had that same duplex been in Hazel Dell instead of Southeast Portland, Washington’s fraction would have been 100%, the Washington tax would have been $100,000, and Oregon’s would have been zero. Total: $100,000.

The river cost that family $31,875 — on a property that generated a car payment.

I am not telling you to sell your Oregon real estate. Sometimes the property is worth keeping and the tax is the price of keeping it. I am telling you that the number is knowable in advance, that it is often never run, and that there are structural questions — how the property is titled, who holds it, how the first death is handled — that can be addressed while you are alive and not afterward.

What about the Oregon property — will my family have to open probate in Oregon too?

If the Oregon real property is titled in your individual name when you die, plan on an Oregon proceeding in addition to the Washington one.

ORS 113.015(1)(b) places venue in any county where the decedent’s property was located at the time of death, or where it is located when the proceeding is commenced. Domicile is not part of that subsection. A Vancouver decedent with a duplex in Portland leaves Oregon real property that needs an Oregon court to clear title, which means a second file, a second set of filing fees, and a second creditor period. (I am licensed in both Oregon and Washington, so one lawyer can handle both sides — but it is still two proceedings.)

This is the clearest case in Clark County for a revocable trust, and it has nothing to do with Washington probate being burdensome. It is not. It is that a funded trust holding the Oregon title means there is no Oregon death transfer to clear — the trust owned the duplex before the death and owns it after. The Oregon estate tax exposure does not disappear. The trust is designed to avoid the Oregon court proceeding.

What is a community property agreement, and should I sign one?

A community property agreement is a Washington tool with no Oregon equivalent, authorized by RCW 26.16.120. It lets spouses or domestic partners agree jointly, in writing, about “the status or disposition of the whole or any portion of the community property,” including property acquired later, to take effect upon the death of either.

The formalities are real. The statute requires an instrument in writing “under their hands and seals,” and it must be “witnessed, acknowledged and certified in the same manner as deeds to real estate are required to be.” It can be amended later the same way.

Used correctly, it is efficient. The community estate can pass to the survivor at the first death without a full probate. It is inexpensive, it is fast, and for a first-marriage couple with shared children and an estate under the Washington exclusion, it can be a sensible piece of a plan.

Used carelessly, it is one of the worst documents a blended family can sign.

Think about what it actually does. Everything goes to the survivor, outright, with no strings. If you have children from a prior marriage, you have just handed your entire share to your current spouse and trusted that person — and whoever that person marries after you — to take care of your kids. There is no trust. There is no residence provision. There is no remainder interest. There is a signature and a hope.

I have written about what happens when a trust splits correctly at the first death but never addresses whether the surviving spouse can stay in the house. A community property agreement does not even get that far. It skips the structure entirely.

Two more limits worth knowing. The agreement “shall not derogate from the right of creditors.” And a court can set it aside or cancel it for fraud or under some other recognized head of equity jurisdiction, at the suit of either party.

There is one genuine federal tax advantage that comes with Washington community property, and this is the piece that CPAs and advisors should be watching. Under 26 U.S.C. § 1014(b)(6), the surviving spouse’s one-half share of community property held under the community property laws of a state is treated as property acquired from the decedent — provided at least half of the whole community interest was included in the decedent’s gross estate. The practical effect is a new basis on both halves at the first death, not just the decedent’s half.

For a Clark County couple holding appreciated real estate or a long-held concentrated position, that is a meaningful difference from the treatment most Oregon couples get across the river. It is also a reason not to casually convert separate property into community property, or community property into separate property, without someone running the tax consequences first. Characterization is not a formality. It drives basis, it drives what each spouse can control at death, and for families who moved here from Oregon or another separate-property state, it is often muddled.

What happens if I die in Clark County without a will?

Washington’s intestacy statute, RCW 11.04.015(1), gives the surviving spouse or domestic partner all of the decedent’s share of the net community estate, plus one-half of the net separate estate if the decedent is survived by issue. If there is no issue but a surviving parent or issue of a parent, the spouse takes three-quarters of the separate estate. If none of those exist, the spouse takes it all.

Read that against Oregon, because the difference is sharper than most people expect and it runs against Washington in exactly the situation where it matters most.

Oregon’s statute distinguishes. Under ORS 112.025(1), a surviving spouse takes the entire net intestate estate when all of the decedent’s descendants are also descendants of that spouse. Under ORS 112.025(2), the spouse takes only one-half if any descendant is not the spouse’s. Oregon noticed the blended family and wrote a different rule for it.

Washington’s statute makes no such distinction. A second marriage with stepchildren and a first marriage with shared children run through the same formula. In a community property state, where the bulk of a long marriage’s wealth is community property, all of the decedent’s share of the net community estate to the survivor is a very large number — and the children from the first marriage are looking at half of a separate estate that may be small or may be nothing.

If you are remarried in Clark County and you have children from an earlier relationship, the Washington default is not a plan. It is a result.

Can a small estate skip probate in Washington?

Sometimes, and the Washington version is narrower than Oregon’s in one way that matters.

RCW 11.62.010 allows collection by affidavit when the value of the probate estate, less liens and encumbrances and excluding the surviving spouse’s or domestic partner’s community property interest, “does not exceed one hundred thousand dollars,” and at least 40 days have passed since the death. It reaches personal property, debts owed to the decedent, and securities.

It does not clear title to real property. If there is a house, this is not your tool.

The $100,000 figure also has no inflation adjustment. It has sat where it sits while Clark County home values and retirement balances did what they did.

Oregon, for comparison, allows a small estate affidavit under ORS 114.510(1)(a) where personal property does not exceed $75,000 and real property does not exceed $200,000 — and Oregon’s version does reach real property. Under ORS 114.515(3), the Oregon affidavit may be filed 30 days after death.

So Washington is lighter on full probate and narrower on the shortcut. Oregon is heavier on full probate and broader on the shortcut. Neither state built a system that quietly handles a Clark County family with a house on this side and a rental on that one.

Where is probate filed in Clark County?

Clark County Superior Court, at the Clark County Courthouse, 1200 Franklin Street, Vancouver, Washington 98660. The mailing address is PO Box 5000, Vancouver, WA 98666.

If the estate also includes Oregon real property, that second proceeding goes to the Oregon circuit court for a county where the property sits — Multnomah County for a Portland rental, Lincoln County for a beach house in Lincoln City, Clackamas County for something in Oregon City or Lake Oswego.

Two courts. Two counties. Two states. One family, trying to settle one estate, during the worst month of their lives.

The decision in front of you

Living in Vancouver means you drew the better jurisdiction. Washington’s exclusion is three times Oregon’s. Washington’s probate, for a solvent estate with a named personal representative, is close to self-directed. Washington gives married couples a basis advantage at the first death that most Oregon couples do not get. Many Clark County families need less planning than their neighbors across the bridge, and I would rather say that out loud than let you buy a structure to solve a problem you do not have.

But the Columbia River is a tax border, and Oregon’s reach does not stop at it. If you own real property or tangible personal property on the Oregon side, you are inside a system with a $1,000,000 entry threshold measured against everything you own, a rate set by the size of your whole estate, and a court that will want its own probate file to clear the title.

The question is not whether you need a trust. The question is narrower and more useful than that. What do you own on the Oregon side, what is it worth today, who is titled on it, and what does the bill look like if you die this year?

That is an afternoon of work while you are alive. It is not available to your family afterward.
