Turn your question into an organized preparation draft

Get a preparation plan, the Oregon process guide, three fillable worksheets and an editable letter. Optional setup below carries your question and document list into the paid PDF.

Personalize your included letter and evidence organizer

Text-based PDF, up to 8 MB / 10 pages. Your file stays in this browser. Only details you confirm are included in your order. Photos and scanned notices currently need manual entry.

Copy details from your assessment notice. We use these to prepare your letter draft, worksheets and evidence list. These are your entries, not a verified property analysis. You can also buy now and fill them in later.

Start by checking the property facts and valuation basis. Record a specific question before choosing supporting evidence. Preparation does not reopen an expired filing window.

Optional notes are included in your purchase record and PDF. Do not include sensitive documents, account credentials or other people’s personal information.

Your filing route to verify

your COUNTY CLERK, who serves as clerk of the Property Value Appeals Board. The form states that no other county office can accept petitions

Form OR-B-RPP

This is the Oregon statewide route. Your county may use its own office, deadline or fee, so confirm those against your assessment notice or the official directory before you file. The jurisdiction exceptions in this guide list the ones we hold.

Open official filing instructions
Add evidence you have already found (optional)

We organize your entries in the paid PDF; we do not verify them or generate comparable sales in the $29 kit. For each record include the address, sale price or assessment, date, official source and why it is relevant. Use the correct valuation date and local evidence rules.

1. Define the question. Compare the area definitions, dates and source documents before assuming either number is correct.

Notice worksheet: property-record errors to verify

“The two area figures differ. Check whether they measure the same space, and verify the current property record before requesting a correction.”

2. Make an evidence list. Use the filing tracker to separate documents you have from documents you still need.

Filing tracker: evidence index

“To collect and label: current property record, dated floor plan and any measurements needed to resolve the difference. Record each source, date and page number.”

Example preparation summary · fictional, not filed

Question: Do the two area figures use the same measurement definition?

Document index: A — current property record; B — dated floor plan. Add source dates and page numbers before relying on either.

Unresolved: measurement basis, current facts and the appropriate local correction or appeal route.

Next action: verify those points with the official local source before making a correction request.

The useful result: one defined issue and a document checklist. You still verify the facts and the correct local filing route. No correction or tax reduction has been established in this example.

These illustrative entries show how to use two fields in the paid worksheets. The paid PDF carries your optional question and document list into editable worksheets and adds a preparation plan for your selected starting point. It does not contain this fictional property or a verified case for your home.

Your starting details

The notice worksheet also helps you record:

  • Property address and parcel identifier
  • State, county, township and reviewing body
  • Assessment year and valuation date

Make this preparation package your own

Add your name, property details and question before buying. Your entries become a personalized letter draft and preparation plan in the paid PDF. You can edit them later; no need to start with an empty letter.

Prepare your Oregon property tax appeal

Have a current notice? Check its deadline and reviewing office, verify the property details, then organize evidence that supports the correction you are requesting. Confirm official forms and fees before filing.

Preparing for a future window? Use the worksheets to review property records, list errors to investigate and plan your evidence. Buying now does not reopen a closed deadline or guarantee lower taxes.

The kit organizes those steps into a reusable guide and worksheets. It does not find comparable properties for you, file an appeal or replace your local authority’s instructions.

How an Oregon appeal works

The short version, free. The paid kit adds the evidence workbook, filing controls, and editable letter.

  1. Oregon gives every property two values: Real Market Value and a Maximum Assessed Value that rises about 3% a year. Your tax is computed on the LESSER of the two, so check both before you do anything.
  2. The practical test: if RMV is higher than the assessed value printed on your statement, then that assessed figure IS your MAV, and a reduction only cuts your tax if it pushes RMV below it. Otherwise you can win the appeal and save nothing.
  3. File Form OR-B-RPP with your COUNTY CLERK, not the assessor, between the date tax statements are mailed (on or before October 25) and December 31. You cannot file before statements go out.
  4. The board hears petitions from the first Monday in February and must adjourn by April 15. If you miss December 31 and your RMV is off by 20% or more on a home, ORS 305.288 gives the Tax Court a MANDATORY late remedy reaching back two extra years.

What to check on your assessment notice

  • Find REAL MARKET VALUE and ASSESSED VALUE. If RMV is higher than AV, your AV equals your Maximum Assessed Value, and that AV figure is the number your RMV has to get below to save you anything.
  • Maximum Assessed Value is usually NOT printed on the statement, and exception value never is. If RMV is lower than AV, or you cannot tell, call the assessor and ask for the MAV.
  • Did you build, remodel or add on last year? Exception or new-construction value is one of the few things a petition can reliably move.
  • Check whether your county charges a filing fee before you post anything. Multnomah is $30 per account and dismisses petitions that arrive without it.

What’s inside

✓The two-minute RMV-versus-MAV test that tells you whether an Oregon appeal can lower your bill at all, using numbers already on your statement.
✓The three exceptions where an RMV cut still saves money even when assessed value is pinned to MAV, including the compression case that most write-ups miss entirely.
✓The county filing fees no state publication mentions, including the $30 that gets Portland petitions dismissed, and the question to ask your clerk.
✓The county clerk rule, the county-by-county filing methods, and the postmark trap that voids a timely-mailed petition.
✓ORS 305.288 in plain terms: the late appeal the Tax Court MUST grant on a 20% dwelling error, with no excuse required, reaching back two extra years.
✓Why good and sufficient cause will not save you, quoted from the statute, so you do not build a late appeal on a ground the law excludes.
✓The increase risk at the Tax Court that does not exist at the board, so you know where to stop.
✓A ready-to-edit petition letter citing the right Oregon statutes.

How it works

  1. Buy the kit — the PDF lands in your inbox instantly.
  2. Run the RMV-versus-MAV test BEFORE you calendar anything. If your real market value sits well above your maximum assessed value, a reduction may not lower your bill by a cent, and Oregon is the one state where the honest first answer is often do not file.
  3. Gather the evidence on the checklist and edit the appeal-letter template.
  4. File the current instrument required by your COUNTY CLERK, who serves as clerk of the Property Value Appeals Board. The form states that no other county office can accept petitions before your deadline.

Different process where you live?

Oregon is not one system. These jurisdictions have local filing routes, forms or deadlines that can differ from the statewide overview. The kit covers each one in its own section.

Multnomah County (Portland)
All property in Multnomah County, the state's largest appeals volume.
Deadline
From the mailing of tax statements through December 31, 2026.
Filed with
The Multnomah County Property Value Appeals Board, filed through the County Clerk (Division of Assessment, Recording and Taxation).
Form
Form OR-B-RPP (150-310-063).
Lane County (Eugene)
All property in Lane County.
Deadline
From the mailing of tax statements through December 31, 2026, hand delivered by 4:00 p.m.
Filed with
The Lane County Property Value Appeals Board, filed through the County Clerk.
Form
Form OR-B-RPP (150-310-063).
Washington County
All property in Washington County.
Deadline
From the mailing of tax statements through December 31, 2026.
Filed with
The Washington County Property Value Appeals Board, filed through the County Clerk.
Form
Form OR-B-RPP (150-310-063).
Deadline: Under ORS 309.100(2) a petition must be filed during the period following the date the tax statements are mailed and ending DECEMBER 31. You cannot file early: the window opens only when statements go out, which ORS 311.250(1) requires on or before October 25, so the practical window is about nine weeks. For the 2026-27 cycle you are appealing the January 1, 2026 value, statements mail on or before October 25, 2026, taxes are due November 15, 2026, and the petition deadline is Thursday, December 31, 2026. December 31, 2026 is a Thursday and is not a holiday, so there is NO weekend extension this year. Where the last day does fall on a weekend or holiday, ORS 187.010(3) moves it to the next business day. File with the COUNTY CLERK: ORS 309.024(2) makes the county clerk the clerk of the board, and the form states that no other county office can accept petitions. From there, an appeal of the board's order goes to the Oregon Tax Court Magistrate Division within 30 DAYS of the order's mailing under ORS 305.280(4), and the Department of Revenue stresses that this is 30 days and not one month. A magistrate decision goes to the Regular Division within 60 days under ORS 305.501(5)(a), again 60 days and not two months.

What Oregon charges to file

These are your county or state’s fees, not ours. Listed so there are no surprises.

  • There is NO statewide Property Value Appeals Board filing fee, and ORS chapter 309 authorizes none. But several counties charge anyway, and no state publication mentions it, which makes this the single easiest way to lose an Oregon petition.
  • Multnomah County (Portland) - $30.00 per account, payable to Multnomah County. If the petition arrives without it you have 20 days from notification to pay or the petition IS DISMISSED.
  • Lane County (Eugene) - $35.00 per tax account, capped at $350.00 for multiple accounts in one platted subdivision under the same ownership.
  • Washington County - no fee. The county states expressly that there is no fee for filing an appeal with the Property Value Appeals Board.
  • Clackamas and Deschutes Counties - neither publishes a fee either way. Treat this as unknown rather than as zero and call the clerk before you file.
  • Oregon Tax Court - $50 to file a complaint in the Magistrate Division, $281 in the Regular Division. Fee deferral or waiver is available for individual taxpayers who cannot afford it.
  • The 31 counties not listed above have not been individually verified. Given that the largest county in the state charges, call your own county clerk and ask rather than assuming.
