How Tax Delinquent Property Sales Work in California
California is a tax-deed state with no post-sale redemption. Properties become tax-defaulted after one year of unpaid taxes; after 5 years (or 3 years for non-residential property), the county tax collector schedules a public auction. Most California counties now run their tax-defaulted property sales online through Bid4Assets or similar platforms. The winning bidder receives a tax deed shortly after the sale, free of all prior tax liens but subject to certain other recorded interests like IRS liens, special assessments, and easements.
Bidding & Auctions
Most California tax-defaulted auctions are held online via Bid4Assets, Realauction, or county-specific platforms. Registration usually opens 30-60 days before the sale and requires a refundable deposit (commonly $1,000-5,000) plus a non-refundable processing fee. Bidding is ascending-bid with a soft close — late bids extend the auction by a few minutes to prevent sniping. The full purchase price is due within a short window after the sale (typically 24-72 hours), payable by wire or certified funds.
Redemption & Penalties
California has no post-sale redemption. The original owner must pay off all back taxes and penalties before the auction begins to keep the property. Once the auction starts, the owner has lost their right to the property. After the sale, the prior owner has 1 year to claim any "excess proceeds" — money left over after taxes, penalties, and costs are paid — but they cannot recover the property itself.
See California Revenue and Taxation Code, Part 6. Specific procedures vary by county — always verify with the local tax assessor/collector before bidding.

Frequently Asked Questions
How often is the San Francisco County list updated?▾
County release schedules vary. Some counties publish weekly or monthly; others publish quarterly or annually. We update the download after collecting a new official release from County Records. A list can be current for the county's release cycle without changing every day. Verify property and tax details with the county before acting.

Each record includes property address, owner name, mailing address, assessed value, property type, and legal description.
Is the download really free?▾
Not yet. We are validating the next publishable San Francisco County list. Join the notification list and we will let you know when a verified sample is ready.
When are California tax-defaulted property sales held?▾
Each county schedules its own tax-defaulted property auction, typically once a year. Many large counties (Los Angeles, San Bernardino, Riverside) hold sales in spring or fall and publish the calendar 60+ days in advance.
Are California tax sales online?▾
Most California counties now conduct tax-defaulted property sales online, primarily through Bid4Assets. A few smaller counties still use in-person sealed bids, but the trend is fully online with deposit-based registration.
Does California have a redemption period after the sale?▾
No. The owner must redeem before the auction begins. After the auction, the buyer takes title — though the prior owner has 1 year to file a claim for excess proceeds (any sale price above the back taxes and costs).
What liens survive a California tax-defaulted property sale?▾
A tax-deed sale extinguishes most private liens (mortgages, judgments) but does NOT extinguish federal IRS tax liens (subject to a 120-day federal redemption window), most special assessments, or recorded easements. Always title-search before bidding.
