The Riverside County tax auction is an online sale of tax-defaulted properties run by the county Treasurer-Tax Collector through the Bid4Assets platform. The next sale opens at 8:00 AM Pacific Time on April 23, 2026, and runs through April 28.1Riverside County Treasurer-Tax Collector.

Registering and Funding Your Bid
Registration happens on Bid4Assets, and the platform will not let you place a bid without a cleared deposit. The deposit is $5,000, refundable if you don’t win.3NBC Los Angeles.

Deposits are submitted by wire transfer or cashier’s check payable to the auction platform, and the funds have to clear before the April 20 cutoff. Follow the exact transfer instructions on Bid4Assets, because a deposit that lands late or routes to the wrong account will not be credited in time. Miss the deadline and you are locked out of the sale.
How the Bidding Runs
Each parcel has its own closing time on its listing page, staggered across the April 23–28 window.1Riverside County Treasurer-Tax Collector. TC-223 Every property carries a minimum bid set by the tax collector. Under California law, that floor cannot be less than the total amount needed to redeem the property, meaning all back taxes, penalties, and costs, plus the sale expenses. Because penalties and interest have compounded over the years the property sat in default, the minimum is generally well above the raw delinquent tax figure.
Bids are placed in set increments through the platform. An overtime feature extends the closing window if a bid comes in during the final minutes; the clock resets in short blocks until the activity stops. That means late sniping doesn’t work, but it also means you need to stay logged in and watching if you’re serious about a parcel. Bid4Assets allows a maximum-bid setting so the system bids incrementally on your behalf, though many buyers prefer to bid manually and react to competition in real time.
Who Can Bid
All bidders must be at least 18 years old.5Riverside County Treasurer-Tax Collector. Procedural Information for Tax Sale – TC 222 The tax collector and their staff cannot participate. A current property owner cannot buy back their own parcel for less than the minimum bid. If you won a parcel at a previous auction and failed to complete the purchase, the tax collector can bar you from bidding for five years.6California State Controller’s Office. Chapter 7 Tax Sale FAQ
Otherwise the field is open. Out-of-state bidders, corporations, and LLCs all participate regularly. State law says “any person, regardless of any prior or existing lien on, claim to, or interest in, the property, may purchase at the sale.”7California Legislative Information.

Paying and Getting the Deed
If you win, full payment is due to Bid4Assets by 1:00 PM Pacific Time on Friday, May 1, 2026.8Riverside County Treasurer-Tax Collector.

Once the Treasurer-Tax Collector receives full payment, the office executes a tax deed transferring ownership to you.9California Legislative Information. California Revenue and Taxation Code 3708 The statute requires the tax collector to record the deed with the County Recorder immediately.10California Public Law.

What Survives the Tax Deed
A tax deed wipes out most pre-existing liens and encumbrances. Mortgages, judgment liens, and deeds of trust are extinguished. Several categories of interests survive the sale, however, and this is where buyers most often get burned.
- Any property taxes and special assessments that become due on the secured roll after the sale date remain your responsibility.
- Recorded easements, separately held water rights, and deed restrictions all survive.
- Federal tax liens are not automatically discharged. The IRS has 120 days from the date of sale to redeem the property by reimbursing you for the purchase price plus interest at 6 percent per year.11Office of the Law Revision Counsel. 26 USC 7425
- Unpaid assessments under the Improvement Bond Act of 1915 and unpaid Mello-Roos special taxes not covered by the sale proceeds can carry forward.
- If a taxing agency did not consent to the sale, its liens survive.
The federal redemption right is the one that catches people off guard. For 120 days after you buy, the IRS can effectively take the property back. You get your money plus interest, but you lose the deal along with anything you spent on improvements or repairs during that window.
Title Isn’t Insurable Right Away
Title companies generally will not issue a policy on property bought at a tax auction. Former owners and former lienholders have one year from the date the tax deed is recorded to challenge the validity of the sale in court. During that year, no title insurer will guarantee clear title.
After the one-year window closes, most buyers still need to file a quiet title action, a lawsuit asking the court to formally confirm ownership and extinguish any remaining claims. Only after a court order does title insurance typically become available. You can sometimes shortcut the process by obtaining quitclaim deeds from the former owner and every prior lienholder, but that is rarely practical with tax auction properties.
A quiet title action in California typically costs several thousand dollars in attorney fees and filing costs and can take months to resolve. Budget for it from the start. Until you have clear, insurable title, selling or refinancing the property is very difficult.
As-Is, No Inspection
The county makes no guarantees about anything. There is no warranty on physical condition, zoning compliance, building code status, environmental contamination, or occupancy. You cannot inspect the interior before bidding. You are buying a legal interest in a parcel based on public records, a drive-by, and your own research.
If someone is living in the property, removing them is your problem, and that may mean formal eviction at your own expense. If the property is contaminated, you could inherit cleanup liability. If the structure was built without permits or violates current zoning, bringing it into compliance is on you. The county’s position is simple: you bid on what you know, and everything you didn’t know is your risk.
Due Diligence Before You Bid
Do the homework well before the auction opens. At minimum, research the parcel’s assessed value, check for recorded easements or encumbrances, drive by the property, review zoning and land use designations, and search federal tax lien records. The county assessor’s and recorder’s offices have online tools that cover much of this.
Pay particular attention to parcels with unusually low minimum bids relative to assessed value. There is usually a reason nobody redeemed the property: environmental contamination, landlocked parcels with no legal access, flood-zone locations, or structures beyond economical repair. The deals that look best on paper are often the ones that cost the most once cleanup, legal fees, and quiet title costs are added in.
Transfer Tax at Recording
When the deed records, expect to pay California’s documentary transfer tax at $1.10 per $1,000 of the purchase price. On a $50,000 winning bid, that comes to $55. Some cities within Riverside County add their own transfer tax on top of the county rate, so confirm the combined figure before finalizing your numbers. Recording fees themselves come out of the sale proceeds, not your pocket.
