An Inherited Oregon Home Keeps Its Measure 50 Cap. The Real Invoices Are the Estate Tax and the Deferral Lien.

Updated August 2026

Two ledgers matter when an Oregon homeowner dies. The county ledger, the one that produces the annual property tax statement, barely notices. Oregon is one of the strictest no-reassessment-at-transfer states in the country: Measure 50, adopted in 1997, gave every property a maximum assessed value that grows no more than 3 percent a year, and nothing in the statute lets a sale, a probate transfer, or a trust distribution reset it. The low taxable value your parents accumulated over decades passes to you with the deed.

The state ledger is a different story. Oregon runs one of only a dozen state estate taxes, with the lowest threshold in the nation at $1,000,000, a line a single Portland-area house can cross on its own. And if the person who died was enrolled in the Senior and Disabled Property Tax Deferral, the state has been quietly paying the property taxes for years, holding a lien, and charging 6 percent interest, all of which comes due on a statutory clock that starts at death. Heirs who focus on the county bill and miss the state bills get the priorities exactly backwards. Here is each piece, in the order the money actually moves.

The Number That Does Not Move: Maximum Assessed Value

Every Oregon property carries two values on the assessment roll. Real market value (RMV) is the assessor's estimate of what the property would sell for, and it moves with the market. Maximum assessed value (MAV) is the Measure 50 number: under ORS 308.146, each year's MAV is the greater of 103 percent of the prior year's assessed value or 100 percent of the prior year's MAV. Your taxes are computed on assessed value, which is simply the lesser of RMV and MAV.

In a market that has appreciated faster than 3 percent a year, which describes most of Oregon since the 1990s, MAV sits far below RMV, and the gap is pure tax savings. The critical fact for heirs: the statute's list of events that break the 3 percent limit does not include a change of ownership. There is no uncapping, no changed property ratio applied at death, no reset to market value because a deed recorded. The MAV your parents' house carried in their last year rolls forward into yours, still growing at most 3 percent annually.

The mechanism of the transfer does not matter either. Probate under a will, intestate succession, a revocable living trust distribution, a transfer-on-death deed, a surviving joint tenant taking by survivorship: none of them appears in the statute, so none of them touches the MAV. In states with uncapping rules, families restructure title for years to dodge a reassessment. In Oregon there is nothing to dodge.

This makes Oregon structurally kinder to heirs than states that revalue at transfer. It also means the smartest move on the county side is often to do nothing except keep paying the bill.

The Six Events That Do Reset MAV, and the One Heirs Trigger by Accident

ORS 308.146(3) routes a property to a new MAV calculation under ORS 308.149 to 308.166 only in these situations:

• New property or new improvements, such as an addition or a major remodel
• Partition or subdivision of the land
• Rezoning, when the property is then used consistently with the new zone
• Omitted property being added back to the roll
• Disqualification from an exemption, partial exemption, or special assessment
• A lot line adjustment

Most of these are choices, not accidents. But the fifth one catches estates. If the person who died had the property in a special assessment program, or held an exemption that ended at their death, the disqualification itself is an exception event, and the exempt slice of value comes back onto the roll under exception math rather than under the 3 percent limit. Heirs planning to subdivide an inherited lot or build on it should also understand they are volunteering for a new MAV on the new value. The inheritance is not what changes the number. What you do next can.

State Bill One: The Deferral Lien the House May Already Carry

Oregon's Property Tax Deferral for Disabled and Senior Homeowners, ORS 311.666 to 311.701, lets qualifying owners age 62 and up, or those on Social Security disability, stop paying property taxes entirely. The Department of Revenue pays the county each November, records a lien against the home, and charges 6 percent annual interest on everything it advances. Many heirs discover the program exists only when they find the lien.

Death is a repayment event under ORS 311.684. The timing rule in ORS 311.686 is precise: the deferred taxes for all years, plus accrued interest, are due to the Department of Revenue on or before August 15 of the year following the calendar year in which the participant died. A parent who dies in March 2026 leaves an account that must be settled by August 15, 2027. Miss that date and the account goes delinquent, and the statute points to foreclosure.

A participant who deferred for fifteen years on a bill of a few thousand dollars a year can easily leave a balance in the tens of thousands once 6 percent compounding is included. Before distributing anything, an estate should request a payoff figure from the Department of Revenue, because this lien is senior to the heirs' interests and follows the property, not the estate.

How to find out whether the lien exists

Deferral participation is easy to miss because the participant stopped seeing tax bills as anything urgent. Three places to look:

• The most recent property tax statement, which flags accounts where the Department of Revenue is paying
• The county deed records, where the department's lien and its recording fees appear against the property
• A payoff request to the Department of Revenue, which is the only way to get the exact balance with interest through a specific date

Who can keep the deferral running

ORS 311.688 allows two people to step into the program instead of paying it off: a surviving spouse who will be at least 60 within six months of the death, or an heir who meets the program's disability criteria. Either must make the property their homestead within two years of the death and file the continuation claim with the department. An adult child who does not qualify cannot inherit the deferral, only the debt.

State Bill Two: The $1 Million Estate Tax Line a House Can Cross Alone

Oregon has no inheritance tax on the people who receive property, but it levies an estate transfer tax on the estate itself under ORS chapter 118, and its threshold is the lowest of any state: $1,000,000, unchanged since 2012 and not indexed for inflation. Every year of home price appreciation pulls more ordinary families over that line. The federal exemption is more than thirteen times higher, so plenty of estates owe Oregon while owing Washington, D.C. nothing.

The rates run from 10 percent to 16 percent, applied to the amount above $1 million, with the 10 percent bracket covering the first $500,000 over the line. Purely as a labeled hypothetical: an estate holding a $600,000 house plus $550,000 in retirement accounts and savings totals $1,150,000, and the Oregon tax on the $150,000 excess would be about $15,000 at the 10 percent bracket rate. The house did not owe the tax, but the house is usually what pushed the estate over, and it is often the only asset large enough to borrow against or sell to pay it.

The paperwork clock: Form OR-706 and the payment are due 12 months after the date of death. An extension of time to file is available, but it does not extend the time to pay, and paying late adds a 5 percent penalty plus interest. Note that the property tax appeal calendar and the estate tax calendar run independently, and a defensible date-of-death appraisal serves both jobs, so commission it early.

Exemptions Are Personal. The Veteran's Discount Dies With the Veteran.

Oregon's property tax exemptions attach to a qualifying person, not to the parcel. The clearest example is the disabled veteran exemption under ORS 307.250, which knocks a slice of assessed value off a qualifying veteran's homestead. When the veteran dies, the exemption does not ride along to whoever gets the house. A surviving spouse who remains unmarried can qualify in their own right, but only by filing their own claim with the county assessor, with the discharge papers, death certificate, and marriage certificate to prove it, and the exemption ends at any remarriage.

Two practical consequences for estates:

• Tell the assessor about the death rather than quietly keeping a personal exemption on the roll. Remember that disqualification from an exemption is one of the ORS 308.146(3) exception events, so the value comes back on the roll either way, and doing it late invites corrections.
• Surviving spouses should file immediately. The veteran exemption claim, and the deferral continuation under ORS 311.688, are both filings the county and state will not make for you.

Why Two Identical Houses Get Different Bills: Compression in One Paragraph

Alongside Measure 50 runs the older Measure 5, which caps the taxes actually charged at $5 per $1,000 of real market value for education levies and $10 per $1,000 for general government. When the math on a tax statement exceeds those limits, the bill is compressed down to them, local option levies first.

The wrinkle heirs should notice: compression is computed on RMV while regular taxes are computed on assessed value, so an inherited home's bill depends on both numbers. A drop in RMV can sometimes cut the bill through compression even when assessed value stays put. That interaction is worth checking before deciding whether an appeal is worth filing at all.

Meanwhile, the Ordinary Bill Keeps Its Own Calendar

None of the above pauses the regular tax bill, which the estate or the heirs must keep current while everything else is sorted out. Under ORS 311.505, Oregon property taxes are payable in thirds:

• November 15: first one-third due. Paying two-thirds by this date earns a 2 percent discount; paying in full earns 3 percent.
• February 15: second one-third due
• May 15: final one-third due

Late installments accrue interest at one and one-third percent per month. An estate short on cash should still make these payments before almost anything else, because unpaid current taxes stack a second lien on top of whatever the deferral program already holds.

The First Fourteen Months, In Order

Every deadline above runs on its own statute, so the safest way to hold them is as one sequence from the date of death:

• Right away: pull the last tax statement and the deed records. Confirm whether a deferral lien exists and which exemptions the owner was claiming.
• Early in the estate: commission a date-of-death appraisal. It anchors the OR-706 if one is needed, and doubles as appeal evidence.
• Surviving spouse, promptly: file the ORS 307.250 veteran exemption claim and, if continuing a deferral, the ORS 311.688 election. Neither happens automatically.
• By October 25: watch for the county tax statement and read the RMV, assessed value, and any lien notations line by line.
• By December 31: petition the Property Value Appeals Board through the county clerk if the RMV overshoots and the MAV or compression math says a cut would actually lower the bill.
• By 12 months after death: file Form OR-706 and pay any Oregon estate tax if the estate tops $1,000,000.
• By August 15 of the year after the year of death: pay off the deferral account, taxes plus 6 percent interest, unless a qualifying spouse or disabled heir has continued it.

Nothing on that list involves the county reassessing the house, because Oregon does not do that. The list is entirely about state bills coming due and personal filings that lapsed at death.

The October Statement and the December 31 Window

County tax statements go out by October 25 each year under ORS 311.250. That statement is the estate's first look at the current RMV, the assessed value, and any liens or exemption changes. If the RMV looks high, the challenge goes to the county Property Value Appeals Board, the body Oregon renamed from the Board of Property Tax Appeals effective January 1, 2024 under HB 2031. Petitions are filed with the county clerk, in Multnomah, Washington, Clackamas, or whichever county holds the property, between the statement mailing and December 31. Lose at the board and the path continues to the Magistrate Division of the Oregon Tax Court, and from there to the Regular Division.

One Oregon-specific warning before you file: because taxes ride on the lesser of MAV and RMV, cutting the RMV only lowers the bill if the reduction pulls RMV below MAV, or if it produces savings through Measure 5 compression. On a long-held family home where MAV sits far under market value, a successful RMV appeal can be a paper victory that changes nothing. Run that arithmetic first. Our Oregon property tax appeal guide walks through the full sequence, and this check is the step most inherited-property owners skip.

When does an appeal make sense on an inherited home? Chiefly when the assessor's RMV overshoots what the estate can prove, and the gap reaches below MAV or into compression territory. Estates hold unusually strong evidence:

• The date-of-death appraisal already commissioned for the estate, a professional opinion of value on or near the assessment date
• Condition photos taken for the listing or the insurance file, which are usually brutally honest about a dated kitchen or a failing roof
• Repair bids gathered while deciding whether to fix the house or sell it as-is
• The record card's blind spots, since decades under one owner often leave the county describing a house that no longer matches reality

The shape of the Oregon inheritance, then: the county tax bill is usually the one thing that takes care of itself, protected by a cap with no death exception. The estate's real work is on the state side, a deferral payoff due the August after death, an estate tax return due twelve months out, and the exemption filings that only living people can make. Sequence those three, and the Measure 50 house does what it has done for decades, which is grow 3 percent a year and no more.
