Official websiteCounty notes
- Auction contact for bidder questions is (714) 834-3411 or TaxAuction@octreasurer.gov, per the county Property Auctions page.
- No tax lien certificates and no over-the-counter sales in Orange County; the only path is the internet deed auction.
- Two auction tracks exist: real property parcels and timeshare intervals, each with its own Bid4Assets storefront, and unsold timeshares get a later re-offer.
- Redemption cuts off at 5:01 p.m. on the last business day before the auction opens, so listed parcels can drop out up to the day before bidding.
- Total cost to a winner is the bid plus a 3% buyer's premium ($100 minimum) plus $0.55 per $500 documentary transfer tax.
- Statutory lists (Notice of Impending Power to Sell, Notice of Public Auction, Notice of Property Tax Delinquency, Three-Year Delinquency) are posted as PDFs on the Published Notices page under R&T 36.5.
- At the time of research the county site still showed the June 25, 2025 auction as the most recent; verify the current date before publishing a forward-looking sale date.
California 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.
