Lane County typically mails its annual property tax statements in the second half of October, with the first payment due in mid-November. For anyone closing on a Eugene home this fall, that statement arrives within weeks of getting the keys. Most new owners open it expecting a number that roughly tracks what they just paid for the house. Often it doesn't, and the gap isn't a mistake by the assessor's office. It's how Oregon's property tax law is built.
Buyers who moved from California sometimes assume the opposite of how things actually work here. California's Proposition 13 resets a home's taxable value to the purchase price every time it sells. Oregon's Measure 50 does the reverse: it passes the seller's assessed value straight through to the buyer, unchanged, and that value keeps growing at up to 3 percent a year from wherever it already was. The price on the closing statement has almost nothing to do with the number the county uses to calculate the bill.
Assessed Value Was Frozen in 1997 and Has Been Compounding Ever Since
Measure 50 took effect in 1997 and rolled every property's assessed value back to its 1995-96 value minus 10 percent. From that starting point, assessed value has been allowed to grow no more than 3 percent annually, with exceptions carved out for new construction, remodels, subdivisions, and rezoning. Real market values in Eugene have moved far faster than 3 percent a year for most of that stretch, so the two numbers on every Lane County tax statement, real market value and assessed value, have drifted further apart with each passing year.
Lane County's own assessment materials put the county-wide pattern in plain terms: on average, residential properties in Lane County are taxed on an assessed value that comes to roughly half of real market value. That average hides a wide range parcel by parcel, because a home's specific assessed value depends entirely on how long it has been compounding at 3 percent, not on what it happens to be worth today.
The City's Own Example Shows How Wide the Gap Gets
Eugene's own finance FAQ uses a set of new apartment buildings to illustrate the mechanism. Two student housing complexes came onto the tax roll in 2023 with real market values of nearly $90 million each. Because new construction is assessed using a county-wide ratio rather than its full market value, the assessed value on those buildings came in at only $36 million, meaning the city collects tax revenue on about 40 percent of what the buildings are actually worth.
The same FAQ makes the residential version of that point even sharper with a direct comparison: one home that sells for $750,000 might pay $2,000 in property tax that year, while another home that sells for the identical $750,000 could pay $10,000. Same price, same year, five times the tax bill. The difference comes down to how long each home's assessed value has been building at 3 percent and what exceptions, if any, reset that clock along the way.
| Home A | Home B | |
|---|---|---|
| Sale price | $750,000 | $750,000 |
| Basis for the tax bill | Assessed value carried over from a long-held, lightly-changed property | Assessed value reflecting a recent addition, remodel, or new construction |
| Annual property tax | Around $2,000 | Around $10,000 |
Two buyers looking at comparable listings, working from the same comps, can end up with carrying costs that look nothing alike once the first tax bill lands.
New Construction and Recent Remodels Carry the Least Cushion
The gap between assessed value and real market value matters for more than the base tax bill. Oregon's Measure 5 caps total property tax at $10 per $1,000 of real market value for general government and $5 per $1,000 for education. When a property's assessed value sits close to its real market value, as it typically does for new construction or a home that just underwent a major addition, there's less room before hitting that ceiling. Long-held homes with a wide gap between assessed and market value rarely bump into the cap, because their higher real market value gives the calculation more headroom.
That means a newly built home or a recently remodeled one in Eugene, even if it's priced right in line with an older home two streets over, may already be sitting closer to what the rate caps allow. The older home has decades of built-in cushion. The new one doesn't.
One Line on Every Eugene Tax Bill Isn't a New Tax at All
Every property tax statement in Eugene carries a line for urban renewal, and it often raises questions from new owners who assume it's an extra charge. It isn't. Eugene has two urban renewal districts, Downtown and Riverfront, and they work through tax increment financing: growth in assessed value within district boundaries gets redirected to fund redevelopment rather than flowing to the county's general pool. The total tax rate doesn't go up because of it. The revenue is simply routed differently.
The Riverfront district is where that mechanism is most visible on the ground. The city's Downtown Riverfront redevelopment turned the old EWEB industrial yard along the Willamette into what's now called the River District, and developer Atkins Dame has already delivered two buildings there: Heartwood, a 95-unit market-rate apartment building completed in April 2024, and Portal, a 130-unit building completed in 2025. A 2024 plan amendment raised the Riverfront district's spending limit by $75 million to keep that pipeline moving.
Several of these downtown and riverfront projects were also approved for Multi-Unit Property Tax Exemptions, which reduce property taxes on qualifying new housing for a set number of years. For a buyer eyeing a newer unit downtown or along the riverfront, that exemption can mean an unusually low tax bill in the near term. It's a temporary reduction, not a permanent feature of the parcel, and the bill typically steps up once the exemption period ends.
What to Check Before You Write an Offer
The purchase price tells you what a home is worth to a buyer and seller today. It tells you nothing about what the county will bill you next November. A few steps close that gap before you're under contract:
- Pull the actual assessed value and payment history for the specific parcel through Lane County's Regional Land Information Database rather than estimating from the sale price or from nearby comps.
- Ask how long the current owner has held the property. A long hold means decades of 3 percent compounding on an older base. A recent sale, addition, or remodel means the assessed value may already sit close to full market value.
- For new construction or converted units near downtown or the riverfront, ask directly whether the property carries a Multi-Unit Property Tax Exemption and when it expires.
- Treat a lender's escrow estimate as a starting point, not a guarantee. It's typically built from the sale price, and Oregon's assessed-value system means the real number can land higher or lower once the actual parcel history is factored in.
- If a value looks off once you own the home, Lane County's Board of Property Tax Appeals hears assessment appeals each year, with the deadline printed directly on the tax statement.
A Few Questions Worth Asking
Does buying a home in Eugene reset the assessed value to what I paid? No. Measure 50 passes the seller's assessed value to the buyer unchanged, and it continues growing at up to 3 percent a year from wherever it already stood. The sale price plays no role in resetting that number.
When will I get my first tax bill after closing? Lane County has mailed annual statements in the second half of October in recent years, according to county reporting on the 2025-26 cycle, with the first payment due in mid-November. Whatever the statement shows reflects the assessed value already on file for that parcel, not the number from your closing documents.
Is the urban renewal line on my bill an added cost? No. It's a redirection of taxes already being collected within the Downtown or Riverfront district boundaries, not an additional charge on top of your regular rate.
