Benton County, Washington — Tax Sale & Surplus Procedure

Local operations layer. The legal framework (redemption periods, surplus rights, statutes, case law) lives on the parent page → washington. This page covers how Benton County actually runs it. Legal information, not legal advice. Last verified: 2026-06-02.

C0. Identity

• County seat: Prosser (most populous city: Kennewick)
• Population: ~206,873 (2020 Census; FIPS 53005)
• Recording unit: county (recorder = Benton County Auditor)
• FIPS: 53005
• Parent legal framework: washington — Washington is a tax-deed, judicial-foreclosure state; the county treasurer is the selling authority (RCW 84.64.080). No private lien certificates. Benton County inherits all of this; the locals below are the operational layer only.

C1. Local Tax Sale

• Conducts own sale? Yes. The Benton County Treasurer initiates foreclosure on real property that has been delinquent for three full years, forecloses judicially in Benton & Franklin Counties Superior Court (shared court), and then conducts a public auction. https://www.bentoncountytax.com/foreclosure-and-distraint
• Platform: Bid4Assets — Benton County has conducted its annual tax foreclosure sale on Bid4Assets’ online auction platform; the county-specific storefront URLs follow the pattern bid4assets.com/storefront/BentonNov<YY> (e.g., BentonNov17 through BentonNov20 for past auctions). A re-offer auction page is maintained at https://www.bid4assets.com/benton. No 2026 auction has been scheduled as of verification date (see C5 notes on interim policy).
• Calendar: Annual, historically culminating in November. Per the county: “Both processes [foreclosure and distraint] start in June of each year culminating in final sale in November.” https://www.bentoncountytax.com/general-questions
  • Historical pattern confirmed by dated Bid4Assets storefronts: Nov 2017, Nov 2018, Nov 2019, Nov 2020 sales all confirmed via search results.
  • Next known sale: None officially announced as of 2026-06-02. As of February 2024 the county announced a pause on all surplus and tax-title property auctions pending a policy update (see C5); no restart date announced as of verification. https://www.bentoncountywa.gov/government/elected_officials/commissioners/property_listings.php
• Rate within statutory range: N/A locally — delinquent-tax interest is set by state statute (RCW 84.56.020), not by the county. See washington.
• Registration & deposit: Per Bid4Assets auction terms (confirmed via search): a single $1,000 deposit +$35 processing fee is required; bidders must complete vesting information before accessing deposit instructions; payment accepted by certified check/money order or wire transfer only (ACH, credit card, money transfers rejected). Auctions are no-reserve.
  • Note: Deposit terms confirmed from prior auction pages retrieved via search; individual storefront pages returned 403 at verification. → see needs_verification.
• Bidder requirements: Online registration on Bid4Assets; certified funds for deposit; vesting information required upfront.
• Delinquent list location: Delinquent property owners are notified via legal notices published in a local newspaper. No dedicated online delinquent list URL was found on the county’s official pages. https://www.bentoncountytax.com/general-questions

C2. Local Redemption → framework: right-of-redemption

• Where/how to redeem locally: Pay all delinquent taxes, interest, penalties, and foreclosure costs to the Benton County Treasurer’s Office (Kennewick or Prosser location). The county’s online payment portal is unavailable for properties in foreclosure after the Certificate of Delinquency is filed; delinquent account payments must be made in full via cash or cashier’s check. https://www.bentoncountytax.com/online-payments
• Deadline: Up to close of business the day before the sale date (RCW 84.64.070). See washington for the statutory framework.
• Local fees: No locally-set fees beyond the statutory amounts — all interest and costs are governed by RCW 84.56.020 and RCW 84.64.
• Redemption contact:
  • Office: Benton County Treasurer
  • Kennewick: 7122 W Okanogan Pl E110, Kennewick, WA 99336 | 509-735-8505
  • Prosser: 620 Market St, PO Box 630, Prosser, WA 99350 | 509-786-2255
  • Email: Treasurer@co.benton.wa.us | Foreclosure@co.benton.wa.us
  • https://www.bentoncountytax.com/foreclosure-and-distraint
• Deviations from state default: None identified. Post-sale redemption does not exist for ordinary owners under Washington law; the three-year right for minors/incompetent persons (RCW 84.64.070) applies by operation of state law.

C3. Local Surplus / Excess Proceeds → framework: surplus-funds

• Claim filing venue: The Benton County Treasurer’s Office (the office that conducted the sale). Per the FAQ: “Any amount received at sale that is more than the taxes and collection costs due will be given to you.” https://www.bentoncountytax.com/general-questions
• Statutory framework: RCW 84.64.080(10) — surplus belongs to the record owner on the certificate-of-delinquency date; claim deadline is three years after the sale date; unclaimed funds deposit into the county current expense fund. See washington for full surplus waterfall.
• Claim form: No dedicated surplus-claim form was found on the bentoncountytax.com forms page at verification. Forms available on that page were limited to property tax refund, REET refund, ACH payment, and address change forms. → needs_verification: confirm whether a dedicated excess-proceeds claim form exists or whether claimants submit documentation directly to the Treasurer’s foreclosure department. https://www.bentoncountytax.com/forms
• Local deadline notes: Three years from date of sale (RCW 84.64.080(10)); the county does not appear to publish a shorter local deadline. Redemption and claim inquiries directed to Foreclosure@co.benton.wa.us.
• Unclaimed list published: Not found on the county’s official website. → needs_verification.
• Contact: Benton County Treasurer, Foreclosure Dept.
  • Email: Foreclosure@co.benton.wa.us
  • Phone: 509-735-8505 (Kennewick) | 509-786-2255 (Prosser)
  • URL: https://www.bentoncountytax.com/foreclosure-and-distraint

▸ For Investors / Operators — Benton County uses Bid4Assets for its annual tax foreclosure auction (historically November; storefront pattern bid4assets.com/storefront/BentonNov<YY>); a $1,000 deposit plus$35 processing fee is required and auctions are no-reserve. Note that as of February 2024 the county paused auctions of county-owned surplus and tax-title land pending a policy update — this applies to already-county-owned parcels, not necessarily to the annual tax foreclosure sale. Redemption must be paid in full (cash or cashier’s check; no online portal) to the Treasurer before close of business the day before the sale. See washington for the 3-year post-sale no-redemption rule for ordinary owners.

▸ For Former Owners — Surplus from a Benton County tax foreclosure is held by the Benton County Treasurer and belongs to the record owner on the certificate-of-delinquency date (RCW 84.64.080(10)). Contact the Foreclosure Department (Foreclosure@co.benton.wa.us; 509-735-8505 Kennewick or 509-786-2255 Prosser) to inquire about or claim surplus funds. The claim deadline is three years from the sale date; unclaimed funds after that window transfer to the county current expense fund.

C4. Offices & Contacts

Note: Benton and Franklin Counties share a Superior Court. The County Clerk listed is for Benton County. The Sheriff conducts judicial-mortgage foreclosure sales (trustee’s sale surplus deposits go to the superior court clerk per RCW 61.24.080).

C5. Local Procedure Notes

• Annual cycle: Foreclosure process begins in June each year; final sale has historically been conducted in November. (Confirmed: bentoncountytax.com/general-questions)
• Online auction platform: Benton County has used Bid4Assets for annual tax foreclosure sales (storefronts dated Nov 2017–2020 confirmed via search).
• Interim policy pause (as of Feb 2024): The county announced it is “not entertaining any offers, nor holding any auctions for Surplus and Tax-Title properties” while updating its Real Property Surplus policies. This policy note specifically refers to tax-title surplus land (already county-owned parcels from prior no-bid auctions), not necessarily the annual tax foreclosure sale. The treasurer’s general-questions page confirms the standard process continues — clarification warranted. → needs_verification. https://www.bentoncountywa.gov/government/elected_officials/commissioners/property_listings.php
• Distraint sales (personal property): Separate from real property foreclosure. Personal property subject to distraint after April 30; mobile homes after October 31. https://www.bentoncountytax.com/foreclosure-and-distraint
• Delinquent notices: Published in legal notices section of a local newspaper (standard WA practice per RCW 84.64.050; county confirmed via FAQ).
• Payment restriction on foreclosure parcels: Online payment portal is suspended once a Certificate of Delinquency is filed; delinquent accounts must be paid in full via cash or cashier’s check at a Treasurer office. https://www.bentoncountytax.com/online-payments
• Court: Foreclosures are filed in Benton & Franklin Counties Superior Court (shared court), consistent with RCW 84.64.050.
• Surplus vs. tax-title land: Benton County distinguishes between: (a) surplus properties — county-owned parcels not acquired via foreclosure, sold under Ch. 36.34 RCW (handled by County Commissioners); and (b) tax-title properties — prior-sale no-bids deeded to the county, sold under Ch. 36.35 RCW (also via Commissioners). Both are distinct from the excess proceeds from a successful foreclosure sale, which are handled by the Treasurer under RCW 84.64.080(10). https://www.bentoncountywa.gov/government/elected_officials/commissioners/property_listings.php

  • Bid4Assets deposit/registration terms ($1,000 +$35) confirmed via search results referencing prior auction pages; the specific storefront pages (bid4assets.com/storefront/BentonNov20 etc.) returned 403 Forbidden at verification. Terms should be re-confirmed when a new sale is announced.
  • Whether the February 2024 auction-pause notice applies to the annual tax foreclosure sale or only to tax-title surplus-land resales; the FAQ still describes a November cycle suggesting the foreclosure auction continues, but this was not reconciled against a current sale announcement.
  • No dedicated surplus/excess-proceeds claim form was found on the Treasurer’s forms page; confirm whether a form exists or whether claimants contact the Foreclosure department directly for instructions.
  • No online delinquent property list URL found; confirm whether a list is published online or only in newspaper legal notices.
  • Benton & Franklin Counties Superior Court clerk information: Josie Delvin identified as County Clerk via search summary — confirm directly from the official clerk’s page; the county pages retrieved did not name the clerk.
  • Confirm current Treasurer’s name (the website bentoncountytax.com does not name the individual treasurer at verification).
