Tax deed sale
- Run by
- Orange County Treasurer-Tax Collector (Office of the Treasurer-Tax Collector, County of Orange)
- Frequency
- annual
- Typical timing
- Held as a public internet auction, historically in June. The county page states: "The most recent Orange County Tax-Defaulted property tax auction was on June 25, 2025. A re-offer of unsold timeshare intervals was on September 17." The Board of Supervisors approved that sale on March 11, 2025. As of this check the office had not posted a later auction date; it directs bidders to subscribe for text or email auction updates at octreasurer.gov/taxauctionreminders.
Registration and deposit
Online only. Bidders must be 18 or older, create a free Bid4Assets account, complete vesting information, and post a deposit before the deposit deadline. For the June 25, 2025 sale the storefront required "A single $5000 deposit (plus a $35 non-refundable processing fee)" received by 4:00 PM ET (1:00 PM PT) on June 18, 2025, one week before bidding opened. Deposits accept only certified check, money order, or wire; ACH, credit card, and money transfers are rejected. First-time bidders complete a USA Patriot Act registration. One deposit covers every parcel in the sale and does not cap bidding. Registration is not required to view parcel information or watch the auction. Losing deposits are refunded within ten business days.
Deed state sale. The Treasurer-Tax Collector sells "Tax-Defaulted Property Subject to Power to Sell" under Revenue and Taxation Code 3691, and the site states the office "DOES NOT offer tax lien certificates, or accept over the counter sales." Auction runs online through Bid4Assets, with separate storefronts for real property and for timeshare intervals. Minimum bid is not less than the redemption amount plus costs; parcels drawing no bids may be re-offered at a reduced minimum before the auction closes. The right to redeem terminates at 5:01 p.m. on the last business day before the first day of the auction. Winning bidders pay in full within five business days of the close, by cashier's check payable to "County of Orange" or cash in person; personal checks, business checks, traveler's checks, and cards are refused, and default forfeits the deposit and can bring a ban from future sales. Add a California documentary transfer tax of $0.55 per $500 of sale price, plus Bid4Assets' 3% buyer's premium with a $100 minimum. All sales are final and properties sell as is; the office supplies no title insurance. Tax deeds generally record within two weeks and are mailed by the Clerk-Recorder. A tax deed clears private liens but not certain public liens, assessments, easements, and IRS liens listed under R&T 3712. Excess proceeds claims run under R&T 4675. The county publishes a GIS parcel map of auction parcels and lists properties in the Orange County Register as state law requires.

California statewide rules
- Redemption
- Tax-defaulted property may be redeemed until the right of redemption is terminated (section 4101). That right terminates at the close of business on the last business day prior to the commencement date of the tax sale, and the start of the auction counts as the sale date no matter when bidding closes. A redemption payment sent by mail must be received in the tax collector's office before that deadline. California has no post-sale redemption period: once the auction opens, a record owner who has not redeemed loses all legal and equitable interest in the property. Two situations revive the right of redemption. The right revives if the property is not sold, and it revives on the next business day if the tax collector approved a credit sale and the buyer did not pay in full by the deadline the tax collector set.
- Deed deposit
- The tax collector may require a deposit and must give public notice before the sale of its amount, payment method, and due date, and of whether it is a condition of bidding or applies toward the purchase price. On a sale the tax collector approves as a deferred-payment transaction, the deposit may be $5,000 or 10 percent of the minimum bid price, whichever is greater. Counties set the specific figure, so confirm it on the county page or auction platform.
- Surplus proceeds
- Sale proceeds first cover statutory distributions, then taxes, assessments, and county costs. Anything left is excess proceeds held in the delinquent tax sale trust fund. A party of interest may file a claim at any time before one year after the tax collector's deed to the purchaser is recorded. Distribution runs first to lienholders of record before the tax deed was recorded, in order of their priority, then to persons with title of record. Excess proceeds not claimed within that year may be transferred to the county general fund.
A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
