California tax sales are public auctions where counties sell properties whose owners have fallen years behind on property taxes. Residential and agricultural parcels become eligible after five years of default; nonresidential commercial property can be sold after three.1California Legislative Information. California Code RTC 3691 The winning bidder pays off the delinquent tax debt, receives a tax deed, and takes the property as-is, with none of the inspections, disclosures, or financing contingencies a normal purchase would include. The appeal is price. The risk is everything the deed doesn’t actually clean up.
When a Property Can Be Sold
A parcel becomes “tax-defaulted” the day the owner misses a payment, but the county cannot sell it immediately. Under Revenue and Taxation Code Section 3691, the tax collector gains the power to sell after five years of default for residential property, multifamily buildings, and agricultural land, and after three years for nonresidential commercial property.1California Legislative Information. California Code RTC 3691 A county can opt out of the shorter commercial timeline by resolution and apply five years to everything.
The timeline can also accelerate to three years on any property type when a city, county, or nonprofit formally asks the tax collector to offer the parcel at the next sale, or when a nuisance abatement lien has been recorded against it.1California Legislative Information. California Code RTC 3691
The owner can stop the sale by paying every dollar owed, including original defaulted taxes, delinquent penalties, redemption penalties, a redemption fee, and county administrative costs. That right of redemption expires at 5:00 p.m. on the last business day before the sale.2San Diego County Treasurer-Tax Collector. Right of Redemption Once bidding opens, redemption is over. California gives no post-sale redemption period, which means a buyer who completes the purchase does not have to worry about the former owner reclaiming the property by paying back taxes.
Public Auctions vs. Agreement Sales
Two different procedures move tax-defaulted property out of county hands, and each is open to a different kind of buyer.
Chapter 7 Public Auctions
Public auctions are the route open to anyone. The property goes to the highest bidder, and the tax collector may hold the sale in person or online.3California Legislative Information. California Code RTC 3692.2 Many counties now run their sales through third-party online auction platforms, which has opened these auctions to bidders statewide. The Board of Supervisors must authorize the sale by resolution before the tax collector can proceed.4California State Controller. Chapter 7 Tax Sales Frequently Asked Questions
Chapter 8 Agreement Sales
Agreement sales skip the auction entirely. Taxing agencies and qualifying nonprofits can buy tax-defaulted parcels through negotiated agreements with the board of supervisors.5California Legislative Information. California Code RTC 3791 Nonprofits are limited to substandard residential properties or vacant land and must use what they buy to serve low-income residents or dedicate the land for public use.6California Legislative Information. California Code RTC 3791.4 Private individual buyers do not qualify for agreement sales.
Finding Upcoming Sales and Registering to Bid
County tax collector websites are the most useful starting point. Most counties publish the upcoming auction list with parcel numbers, addresses, and minimum bids well before the sale date. Legally, the tax collector must also publish notice of the sale once a week for three consecutive weeks in a newspaper of general circulation, with the first publication at least 21 days before the sale.7California Legislative Information. California Code RTC 3702
Registration procedures vary by county. Expect to supply your legal name or entity name, taxpayer identification number, and contact details, and to create an account on whichever online platform the county uses. Deadlines close well before the auction date, often a week or more out.
A deposit is almost always required. The amount varies, and counties generally insist on a cashier’s check or wire transfer. Personal checks and credit cards are typically not accepted.
Due diligence is on you. The property sells as-is, with no warranty about condition, occupancy, zoning, or title status. Pull a title report, drive the parcel, check for recorded liens and environmental issues, and verify the address matches what you think you’re buying. Bidding blind on a parcel number is how new buyers end up with landlocked slivers, uninhabitable structures, or title problems that cost more to fix than the property is worth.
Bidding, Payment, and the Tax Deed
Bidding opens at the minimum bid, which equals the total needed to redeem the property plus county costs: defaulted taxes, delinquent penalties, redemption penalties, a redemption fee, and any outstanding property tax postponement loan balance.8California Legislative Information. California Code RTC 3698.5 No bid below that amount will be accepted.9California Legislative Information. California Code RTC 3706 If the parcel doesn’t sell, the tax collector can lower the minimum and reoffer it later.
Win the bid and the clock starts immediately. Payment windows vary by county and are measured in business days, not weeks. Some counties demand full payment within 24 hours; others allow three business days. The sale becomes legally complete when the tax collector receives payment in full.10California Legislative Information. California Code RTC 3707 Miss the deadline and you forfeit the deposit and the property. Have the funds staged before you place a bid.
After payment clears, the tax collector executes a tax deed and records it with the county recorder. Recording can take several weeks. The buyer also owes documentary transfer tax of $0.55 per $500 of the purchase price, and some cities add their own transfer tax on top.
What the Tax Deed Clears and What Survives
A California tax deed conveys title free of most pre-sale encumbrances. Mortgages, deeds of trust, and private judgment liens recorded against the former owner are generally wiped out. That is the central reason tax sales attract buyers at all.
Revenue and Taxation Code Section 3712 then lists what survives anyway:11California Legislative Information. California Code RTC 3712
- Easements, prescriptive easements, separately held water rights, and recorded restrictions on the property.
- Future tax installments and special assessments that will appear on the secured roll after the sale date.
- Special assessment liens not included in the redemption amount at the time of sale.
- Federal IRS liens that federal law does not allow the sale to discharge, whether or not the tax collector notified the IRS.
- Unpaid Mello-Roos special taxes not satisfied by sale proceeds or being collected through a separate foreclosure.
- Unpaid assessments under the Improvement Bond Act of 1915 not covered by sale proceeds.
- Unaccepted recorded offers to dedicate the property for public use, and recorded options held by a taxing agency to buy the property.
The IRS lien exception has its own twist. When a federal tax lien exists on the property, the IRS has 120 days after the sale to redeem by paying the purchaser the price plus interest and allowable expenses.12Office of the Law Revision Counsel. 28 USC 2410 If the IRS acts, you get your money back and lose the property. Check for federal tax liens before bidding, because the government can unwind an otherwise finished sale for four full months.
Getting Title You Can Insure, Sell, or Borrow Against
Here is the part that catches first-time buyers off guard. A tax deed by itself usually is not enough to obtain title insurance. Title insurers worry about claims from former owners, lienholders whose interests may not have been properly extinguished, parties with unrecorded interests, and procedural errors in the sale. Without title insurance, selling the property to a conventional buyer or using it as mortgage collateral is generally not possible.
The standard fix is a quiet title action, a lawsuit asking a court to declare your ownership valid against all other claimants. An uncontested California quiet title action typically runs several thousand dollars in attorney fees and court costs and takes six to twelve months. Build that time and expense into your bid math from the start.
If the former owner or a tenant still occupies the property, the county will not evict them for you.4California State Controller. Chapter 7 Tax Sales Frequently Asked Questions You handle the eviction yourself through the standard California process, which adds further time and legal expense before you can take possession.
Excess Proceeds for Former Owners
If you lost a property to a tax sale and arrived here looking for the money left over, there is a claim process. When the auction price exceeds the minimum bid, the surplus (after county costs) goes into a delinquent tax sale trust fund.13California Legislative Information. California Code RTC 4674 Lienholders of record are paid first in order of priority, then anyone who held title before the tax deed was recorded.14California Legislative Information. California Code RTC 4675 Claims must be filed within one year of the date the tax deed is recorded. After that, unclaimed funds can be moved into the county general fund, and the chance to recover anything closes with them.
