Appeal deadlines by county
Assessment season is the only season this fight exists. These are the standard filing rules for the jurisdictions we cover deeply, from our versioned rules data with official sources. Your own notice can carry its own date — that one wins. Always confirm with the county.
| Jurisdiction | Where you appeal | Filing rule | Season | Fee |
|---|---|---|---|---|
| Clackamas County, Oregon | Clackamas County Property Value Appeals Board (PVAB — formerly the Board of Property Tax Appeals, BOPTA) | Petition must be filed with the County Clerk by December 31 following the mailing of the tax statement (next business day if Dec 31 falls on a weekend or legal holiday). | Tax statements mail in October. PVAB petitions are due December 31. Hearings run roughly February–April. | No filing fee for a PVAB petition (re-verify with the Clackamas County Clerk). |
| Multnomah County, Oregon | Multnomah County Property Value Appeals Board (PVAB — formerly the Board of Property Tax Appeals, BOPTA) | Petition must be filed with the county by December 31 following the mailing of the tax statement (next business day if Dec 31 falls on a weekend or legal holiday). | Tax statements mail in October. PVAB petitions are due December 31. Hearings run roughly February–April. | No filing fee for a PVAB petition (re-verify with Multnomah County). |
| Washington County, Oregon | Washington County (OR) Property Value Appeals Board (PVAB — formerly the Board of Property Tax Appeals, BOPTA) | Petition must be filed with the county by December 31 following the mailing of the tax statement (next business day if Dec 31 falls on a weekend or legal holiday). | Tax statements mail in October. PVAB petitions are due December 31. Hearings run roughly February–April. | No filing fee for a PVAB petition (re-verify with Washington County). |
| King County, Washington | King County Board of Equalization (BOE) | Petition must be filed with the King County Board of Equalization by July 1 of the assessment year OR within 60 days after the date the value-change notice was mailed, whichever is LATER. The mailing date is printed on your notice — the clock runs from that date, not the day you opened it. | Value notices mail area-by-area, roughly May through November. Your 60-day window starts at YOUR notice's mailing date — check the notice, not the calendar. | No filing fee (re-verify with the King County BOE). |
| Clark County, Washington | Clark County Board of Equalization (BOE) | Petition must be filed with the Clark County Board of Equalization by July 1 of the assessment year OR within 30 days after the date the value-change notice was mailed, whichever is LATER. (State law lets counties extend this window to up to 60 days — confirm Clark County's current window with the BOE before relying on day 31–60.) | Notices of Value generally mail in spring/summer; the filing window runs from YOUR notice's printed mailing date. | No filing fee (re-verify with the Clark County BOE). |
| California (statewide rules — county windows vary) | Your county's Assessment Appeals Board (in some small counties, the Board of Supervisors sitting as the Board of Equalization) | Formal appeal (Application for Changed Assessment, form BOE-305-AH) must be filed in the regular filing window: July 2 – September 15 in counties where the assessor mails assessment notices to all taxpayers by August 1, and July 2 – November 30 in the rest. CHECK YOUR COUNTY — the two windows differ by 11 weeks. Supplemental and escape assessments have their own 60-day windows from the notice date. | Assessed-value notices mail around July; the formal window opens July 2 and closes September 15 or November 30 depending on county; tax bills mail in October. | Varies by county: many are free; some charge a processing fee (roughly $30–$60). Re-verify with your county clerk of the board. |
| Texas (statewide rules — every county has an Appraisal District) | The Appraisal Review Board (ARB) of your county Appraisal District | Protest must be filed by May 15 OR within 30 days after the Notice of Appraised Value was delivered, whichever is LATER (Tex. Tax Code §41.44). If the deadline falls on a weekend or holiday, it moves to the next business day. File even if you're still gathering evidence — you can supplement later. | Notices of Appraised Value mail April–May; the default protest deadline is May 15; informal meetings and ARB hearings run May–July; tax bills mail in October. | No filing fee for an ARB protest. |
