California Tax Sale Calendar: When Each County Auctions Tax-Defaulted Property

Dated sales, 2026–27

Sutter's date comes from the Bid4Assets calendar only and is not confirmed on a county page; Santa Clara's registration deadline had already passed when read; Nevada's “register by” date is when registration opens. Sacramento (February 2027), Mariposa (August 2027), Placer (fall 2027), Colusa (spring 2027), Tehama (first half of 2027) and San Diego (2027, date to be set) have named a month or season only. Alpine, Amador and Inyo say no sale is scheduled. Every date should be re-checked on the county's page, linked in the table below.

The statutory clock

1. Default. Secured taxes unpaid at the end of the fiscal year (June 30) make the property tax-defaulted; redemption penalties of 1.5% a month begin (§3436, §4103). The delinquency page has every county's unpaid share.
2. Power to sell. §3691(a)(1)(A): “Five years or more, or three years or more in the case of nonresidential commercial property, after the property has become tax defaulted, the tax collector shall have the power to sell” the property. A county's board of supervisors may elect by ordinance or resolution to keep the five-year period for nonresidential commercial property (§3691(a)(1)(C)). Three years also applies where a city, county or nonprofit, or the holder of a nuisance-abatement lien, has asked that the property be offered (§3691(b)(1)(A)). “Nonresidential commercial property” is everything except a single-family or multifamily residential unit and its land and land zoned and used for commercial agriculture (§3691(a)(1)(D)).
3. Notice and the four-year window. The collector must offer the property within four years of gaining the power to sell (§3692), after mailed and published notice to the owner and parties of interest (§3701–§3704).
4. Redemption ends. The owner may redeem by paying all taxes, penalties and costs until the close of business on the last business day before the sale (§3707).
5. The sale. A public auction to the highest bidder at or above a minimum the collector sets (§3698.5), after the collector's notice of intended sale and the board of supervisors' approval (§3698, §3699); unsold parcels may be re-offered, and the dated list above labels re-offers, follow-up and supplemental sales. Sealed-bid sales and “Chapter 8” agreement sales to public agencies and nonprofits run alongside the auction in some counties (§3771 and following).
6. The deed. The tax deed conveys title free of most encumbrances, but §3712 keeps a list alive: taxes and assessments not yet due, Mello-Roos and 1915 Act assessment installments not paid from the sale proceeds and not already in foreclosure, easements and recorded restrictions, federal tax liens that the sale does not discharge under federal law (§3712(g)), and a few others; read the section before bidding. A challenge runs on §3725's clock: a petition to the board to rescind the sale (§3731) within one year after the deed is executed, then court within one year of the board's decision.
7. Excess proceeds. §4675(a)(1): a party of interest may claim “at any time prior to the expiration of one year following the recordation of the tax collector's deed to the purchaser”. When the excess is more than $150 the county must notify parties of interest of the right to claim (§4676); excess that goes unclaimed may be transferred to the county general fund (§4674).

Every county

58 counties; 47 publish the date of their last sale, 41 link an excess-proceeds claim page, 3 say no sale is scheduled. Parcel counts are as each county or platform publishes them and are not comparable across counties (some count parcels listed before redemptions, some sold after). “—” means not published on the pages read.

County names link to the tax collector's sale page; “excess proceeds” links the county's claim page where one exists. The full notes for every county are in the download: CSV. Read Sun, October 25, 2026; sale platforms are named as the counties name them and are not endorsements.
