Marion County Tax Estimator

How property tax works in Marion County

Your bill is the assessed value of your home multiplied by the combined rate of every authority that taxes it — the county, the school district, the city or township, and often a fire or library district. Those rates are set separately and added together, which is why two houses of identical value on opposite sides of a district line can owe different amounts.

Across Marion County, the median home is worth $383,300 and the median property tax bill is $3,382. Dividing one by the other gives the effective rate of 0.882% used above. That is the honest way to estimate a bill without knowing which districts a specific address falls into.

Marion County in the national picture

Marion County is an ordinary American county on this measure. Its 0.88% sits within 15% of the national median of 0.84%, which puts it in the broad middle where most of the country lives. That matters when you are comparing offers: the rate here is not the thing that will decide the deal either way.

For scale, the range across the whole country runs from about 0.08% at the bottom to 3.64% at the top. That is a spread of more than twenty to one on the same house, and it is decided almost entirely by where the line on the map falls rather than by anything about the property itself.

What 0.88% costs at each price point in Marion County

The rate is a percentage, so the bill scales straight with the value the assessor puts on the property: $200,000 → $1,765 a year ($147 a month); $350,000 → $3,088 a year ($257 a month); $500,000 → $4,412 a year ($368 a month); $750,000 → $6,617 a year ($551 a month); $1,000,000 → $8,823 a year ($735 a month).

The median home in Marion County is assessed around $383,300, which is why the typical bill here lands near $3,382. If you are looking above that price, read the row that matches your budget rather than the median — the median describes the county, not your purchase.

One caveat that catches people out: these figures use assessed value, and in many states that is not the same as the price you paid. Some states assess at a fixed fraction of market value, and some cap how fast an assessment can rise for an existing owner. Both make the published rate look higher or lower than what a specific household actually pays.

What property tax takes out of a Marion County income

Median household income in Marion County is $74,624 and the median property tax bill is $3,382. That is 4.5% of gross household income going to property tax alone — before any income tax, before FICA, and before the mortgage the tax sits on top of.

Above about 4%, property tax stops being a line item and starts being a constraint. In Marion County it is 4.5%, which means a household here is carrying roughly $282 a month in tax on the home before principal, interest or insurance. It is the single strongest argument for checking the assessment rather than assuming it is right.

This is also the number that rent quietly reflects. A landlord in Marion County pays the same $3,382 on a comparable property and prices it into the lease, so the tax reaches renters too — it just arrives without a bill attached.

Why Oregon counties charge such different rates

Property tax is set locally, so Oregon does not have one rate — it has 36. They run from 0.53% in Josephine County to 1.01% in Gilliam County, with Marion County at 0.88%, 29th cheapest of 36.

That is a comparatively tight range for a US state — 1.9 to one between the extremes — which usually means Oregon funds a large share of school costs at state level rather than leaving districts to raise it locally. Where the state carries more, local rates converge.

The practical consequence is that a rate you were quoted for Oregon as a whole is close to meaningless. The number that applies to you is the one for your county, and often for your district within it.

Property tax and income tax in Oregon, together

Oregon taxes income as well as property, so a full picture of what living in Marion County costs needs both. The property side is local and is on this page; the income side is set at state level and applies wherever in Oregon you live.

The two are worth adding together rather than comparing separately, because states trade them off against each other. A state with a low income tax often leans harder on property, and vice versa — which is why a single-tax comparison between two states can point the wrong way.

What the Marion County figure is, and what it is not

The 0.88% on this page is an effective rate: the Census Bureau's median property tax paid in Marion County ($3,382) divided by its median home value ($383,300), both from the American Community Survey five-year estimates. It is a real, citable measure of what owners here actually pay.

It is not a millage rate, and it is not the number on your tax bill. Your bill is the sum of every levy that reaches your parcel — county, school district, city or township, and often a fire, library or water district — applied to your assessed value after any exemption you qualify for. Two houses of the same value on opposite sides of a district line in Marion County can owe different amounts, and both are correct.

Use this figure to compare Marion County against other places and to sanity-check an escrow estimate. Use the assessor's roll to find out what you owe.

Marion County at a glance

Marion County has a population of about 346,532, 130,600 housing units, and a median household income of $74,624.

At that size there are typically a handful of taxing districts inside the county, so the rate on this page is an average across them rather than the figure for any one address.

The Oregon rules that change your Marion County bill

Measure 50 caps growth in assessed value at 3% a year for existing property, and it reset every assessed value in 1997 to 90% of the 1995–96 figure. Two identical Oregon houses can therefore carry very different assessed values purely because of what they were worth thirty years ago. The consequence for Marion County is that the effective rate on this page describes the county as a whole, not your position in it: a recent buyer and a long-term owner of identical houses here are taxed on different values, legally and by design.

Oregon carries two values on every property and taxes the lower one. Measure 50 reset assessed value in 1997 to 90% of the 1995–96 figure and caps its growth at 3% a year; real market value is tracked separately and is usually far higher. Because assessed value does not reset on sale, the gap between the two has widened for decades, and the ratio between them differs from one Oregon property to the next.

Measure 5 adds a hard rate ceiling on top: $10 per $1,000 of assessed value for general government and $5 per $1,000 for education. When the two collide, levies are compressed rather than the cap being breached.

These are Oregon rules and they apply in every county in the state, Marion County included. What varies locally is the rate, not the relief — so if you qualify for the relief and have not claimed it, the Marion County assessor is where that gets fixed.

The ten-year figure, which is the one that decides a purchase

A single year's property tax is a number people accept without much thought. The decade is the number that changes decisions, because unlike a mortgage it never amortises away and unlike income tax it does not fall when your income does.

On Marion County's median home value of $383,300, held ten years with assessed value rising at the capped 3% a year, Marion County collects about $38,769. The cheapest county in the state collects $23,205 over the same period and the dearest $44,301 — a spread of $21,096 on identical property, decided entirely by location.

The same house at the national median rate of 0.84% would run $36,783 over ten years, so Marion County costs about $1,986 more across the decade than a typical American county would.

Set that against the mortgage to see the weight of it. On a $383,300 purchase the ten-year property tax bill in Marion County is roughly 13% of the amount financed at 80% loan-to-value — before insurance, before maintenance, and before any millage increase. It is the largest recurring cost of ownership after interest, and the only one that a district can raise without asking you.

Treat the figure as an order of magnitude rather than a forecast. It assumes Marion County's current effective rate holds, and rates move with district budgets, which the value cap does not limit — it caps the base, not the levy. What it is reliable for is the comparison: the gap between two counties is far more durable than either absolute number.

Appealing a Marion County assessment: what it is worth

You cannot appeal the tax rate — that is set by budget votes you have no standing to challenge individually. What you can appeal is the assessor's opinion of your property's value, and that is a factual claim you can be right or wrong about.

The arithmetic decides whether it is worth your afternoon. On the median home in Marion County, $383,300, the bill runs about $3,382 a year. A 10% reduction in assessed value is worth roughly $338 a year, and because the corrected value carries forward it is nearer $1,691 across five years. Under $60 a year, the paperwork rarely pays; over $400, it usually does.

What wins is comparable sales, not hardship. Three to five recent arm's-length sales of genuinely similar properties — same neighbourhood, similar size, age and condition — near your valuation date. What loses is what the bill does to your budget, what the previous owner paid, or that the rate went up. Assessors decide value; none of those speak to value.

Also check the record itself before arguing valuation, because errors are commoner than contested opinions: square footage that includes an unfinished basement, a bathroom that does not exist, a garage counted twice, land area from a survey predating a lot split. A factual correction is usually granted without a hearing.

Deadlines are set locally here and are short — often thirty to forty-five days from the date the assessment notice was mailed, not from when you read it. Check the notice itself for the date, because missing the window generally forfeits the year regardless of how strong the case was.

How the bill is paid, and what happens if it is not

Most owners with a mortgage never pay this directly. The servicer collects roughly $282 a month alongside principal and interest on the median Marion County bill, holds it in escrow, and pays the county when it falls due. The consequence is that a rise reaches you as a change in your monthly payment months after the fact, with no obvious connection to the assessment notice that caused it.

Read the annual escrow analysis when it arrives. It shows the bill actually paid, and it is the cheapest way to catch an assessment you would have appealed had you noticed — by the time the payment changes, the appeal window for that year has usually closed.

The weight here is unusual enough to plan around: the median bill is 4.53% of median household income, so the monthly escrow line is a substantial fixed commitment rather than a rounding item. Lenders qualify borrowers on the full payment including it, which is why a high-tax jurisdiction reduces the price a given income can support — the tax competes with the mortgage for the same debt-to-income headroom.

Unpaid property tax is also secured against the house itself, which is what separates it from every other tax. States permit a tax lien, and eventually a tax sale, at the end of a statutory redemption period. It is slow and heavily noticed, so it is nearly always avoidable — but the mechanism means an unpaid property tax bill can never simply be written off the way an unpaid income tax debt sometimes is.

The Oregon counties either side of Marion County

The Oregon counties immediately cheaper than Marion County: Baker County at 0.88%, Clackamas County at 0.87%, Washington County at 0.87%. On a $400,000 home the move from Marion County to Washington County would save about $54 a year.

Immediately more expensive: Union County at 0.89%, Linn County at 0.91%, Multnomah County at 0.96%. If you are weighing Marion County against Union County, the rate gap on a $400,000 home is about $13 a year — worth knowing, but rarely the largest difference between two places.

Comparisons like these are the reason to use an effective rate rather than a millage. Millage rates are not comparable across county lines because assessment practices differ; tax paid over value paid is.

What actually sets your Marion County bill

Three numbers decide your bill, and the rate is only one of them. The first is assessed value, and Oregon does not reach it by a single fixed fraction. Oregon carries two values on every property and taxes the lower one. Measure 50 reset assessed value in 1997 to 90% of the 1995–96 figure and caps its growth at 3% a year; real market value is tracked separately and is usually far higher. Because assessed value does not reset on sale, the gap between the two has widened for decades, and the ratio between them differs from one Oregon property to the next.

The second is how fast that value is allowed to move, and Oregon restrains it: 3% a year on a qualifying home. That single rule means the published Marion County rate is an average over owners in very different positions, not a prediction of your bill.

The third is the combined rate of every authority that reaches your parcel — the county, the school district, the city or township, often a fire or library district. They are set separately and added, which is why two houses of identical value on opposite sides of a line in Marion County owe different amounts and both figures are correct.

Buying in Marion County? Read this first

Property tax is the part of the monthly cost buyers most often underestimate, because it does not surface until the lender builds the escrow. On a $400,000 home in Marion County it adds roughly $294 a month on top of principal, interest and insurance — $3,529 a year.

And here is the Oregon trap. Assessed value under Measure 50 does NOT reset on sale — it keeps growing at 3% from its 1997 base. Oregon is one of the few states where buying does not trigger a revaluation, which is why assessed and market values here diverge so widely.

Then ask what relief you qualify for in your first year. Deadlines are short and often fall early in the year. Relief that is not claimed is not given.

If your Marion County assessment looks wrong

You can contest the assessed value. You cannot contest the rate — that is set by elected bodies and is not open to appeal. So the question to answer before filing is narrow: would this property actually sell for what the assessor says it is worth?

Gather comparable sales close to the assessment date rather than to today. An assessor is defending a valuation as of a particular day, and recent sales that postdate it carry little weight.

Deadlines are short and usually run from the date the assessment notice is mailed rather than from when you opened it. The Marion County assessor's office is where the clock is published, and missing it costs the whole year — there is no late appeal in most jurisdictions.

Marion County property tax questions

How much is property tax in Marion County?

The effective rate in Marion County is 0.88%, from a median tax bill of $3,382 on a median home value of $383,300. On a $400,000 home that is about $3,529 a year, or $294 a month once it is in escrow.

Is property tax high in Marion County?

No, it is close to typical. Marion County charges 0.88% against a national median of 0.84%, which puts it in the broad middle where most of the country sits.

Which Oregon county has the lowest property tax?

Josephine County at 0.53%, with Gilliam County the most expensive at 1.01%. Marion County sits at 0.88%, 29th cheapest of the 36 Oregon counties with published data.

Will my Marion County tax bill change when I buy?

Assessed value under Measure 50 does NOT reset on sale — it keeps growing at 3% from its 1997 base. Oregon is one of the few states where buying does not trigger a revaluation, which is why assessed and market values here diverge so widely.

Do seniors pay property tax in Marion County?

Measure 5 adds a hard rate ceiling on top: $10 per $1,000 of assessed value for general government and $5 per $1,000 for education. When the two collide, levies are compressed rather than the cap being breached. That is a Oregon rule and it reaches Marion County like every other county in the state; the Marion County assessor or treasurer handles the application.

Can my Marion County assessment go up without limit?

No. Oregon caps the annual increase in assessed value at 3% on a qualifying home. Measure 50 caps growth in assessed value at 3% a year for existing property, and it reset every assessed value in 1997 to 90% of the 1995–96 figure. Two identical Oregon houses can therefore carry very different assessed values purely because of what they were worth thirty years ago.

Is my Marion County home taxed on its full market value?

Not straightforwardly. Oregon carries two values on every property and taxes the lower one. Measure 50 reset assessed value in 1997 to 90% of the 1995–96 figure and caps its growth at 3% a year; real market value is tracked separately and is usually far higher. Because assessed value does not reset on sale, the gap between the two has widened for decades, and the ratio between them differs from one Oregon property to the next.

Can I appeal my Marion County assessment?

You can contest the assessed value, but not the rate — the rate is set by elected bodies and is not open to appeal. Deadlines are short and usually run from the date the assessment notice was mailed rather than from when you opened it. The Marion County assessor's office publishes the current window, and in most jurisdictions there is no late appeal.

Does Oregon have an income tax as well?

Yes. Oregon taxes income at graduated rates up to 9.90%, on top of the property tax on this page. Worth adding the two together before comparing Oregon against anywhere else.

Do I need a parcel number to use this calculator?

No, and that is deliberate. The Marion County assessor's own estimator generally asks for one, which is fine if you already own the property and useless if you are deciding whether to buy it. This works from the home value instead. It is an estimate built on the county's effective rate, which averages across every district inside Marion County, so your exact bill depends on your district combination and on any exemption you qualify for. For the binding figure, the Marion County assessor or treasurer is the authority.
