San Joaquin County tax sales, California

Verified

San Joaquin is the second dated future sale in this set, and the furthest out. The county auctions page, gives a date of auction of March 17 to March 18, 2027 on Bid4Assets, with the storefront link to be provided at a later date. The March 2026 sale, which ran March 11 to March 12, 2026, is the template for the 2027 terms: 125 parcels in the results, of which 104 were redeemed before the sale, 15 removed, 2 drew no bids, and 4 sold, which is the highest redemption share in this set and a warning against counting list size as supply. A reoffer was published for May 27 to May 28, 2026.

Next sale: Wednesday, March 17, 2027 to Thursday, March 18, 2027. Dated sale published on the county auctions page read November 9, 2026: March 17 to March 18, 2027, starting at 8:00 a.m. and closing at various times, on bid4assets.com, with the link to be provided at a later date. The registration and deposit deadline for that sale was not published on the page read, so the 2026 deadline is stated below only as the past pattern.

San Joaquin is small and redemption heavy: 4 of 125 listed parcels sold in March 2026, for $57,500, $69,077, $126,500, and $427,500. Treat the March 2027 list as a research list first and a buying list second, and recheck it close to the sale date.

Dates and deadlines

Next sale	Wednesday, March 17, 2027 to Thursday, March 18, 2027
Sale date and pattern	One online auction a year, in March, on Bid4Assets. Next sale: Wednesday, March 17, 2027 to Thursday, March 18, 2027, starting at 8:00 a.m. Pacific Time. The March 2026 sale ran March 11 to March 12, 2026, with a reoffer May 27 to May 28, 2026.
The list	The parcel list is published in the county notice of public internet auction, with parcel numbers, names, addresses, and minimum bids, and linked from the county auctions page. The 2026 results show how fast the list shrinks: 104 of 125 parcels were redeemed before the March 2026 sale. A list cost is not published on the auctions page read November 9, 2026.
Registration and deposit	Create a Bid4Assets account, complete vesting information, then fund the deposit. The deposit is $5,000 plus a $35 non refundable Bid4Assets processing fee, and it must be received by Bid4Assets by certified check or wire no later than 1:00 p.m. Pacific Time one week prior to the tax sale. For the 2026 sale the registration deadline was Wednesday, March 4, 2026 at 1:00 p.m. Pacific Time; the 2027 deadline was not published as of November 9, 2026.
Minimum bid and how bidding works	Bidding is in increments of $100 or higher until the parcel is sold to the highest bidder, and no bid is accepted for less than the minimum bid. Current secured property taxes for 2025 to 2026 are not included in the minimum bid amount, so the winner must pay those separately and on time.
Redemption before the sale	Parties of interest have until 5:00 p.m. Pacific Time on the day prior to the tax sale to redeem in certified funds, meaning cash, cashier check, or wire transfer. For the 2026 sale the cutoff was Tuesday, March 10, 2026 at 5:00 p.m. Pacific Time. There is no extended right of redemption in California.
Reoffer	Any parcel remaining may be reoffered on the internet at bid4assets.com. For the 2026 sale the reoffer was published as May 27 to May 28, 2026. A reoffer date for the 2027 sale was not published as of November 9, 2026.

Research San Joaquin County parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across San Joaquin County, searchable by address, owner, or county, including parcels that never reach a sale list.

How California tax defaulted property sales work

Default runs on a five year clock. Property taxes that go unpaid become tax defaulted. After five years of default (three years for nonresidential commercial property and the other classes the code names), the property becomes subject to the tax collector's power to sell under Revenue and Taxation Code Section 3691. Until that clock runs, there is nothing to buy: California sells no tax liens.
The county sets a Chapter 7 auction. With the board of supervisors' approval, the tax collector publishes notice and offers the property at public auction under Chapter 7 of Part 6. The minimum price is set by Section 3698.5(a): not less than the total amount necessary to redeem the property, plus costs. Most of the counties in this set now sell online under the electronic auction provisions (Section 3692.2); the county's own tax sale page names the platform and the terms.
The owner can stop the sale until the last business day. Redemption stays open until the close of business on the last business day before the sale begins (Section 3707), and a redemption in full ends the power to sell that parcel. Parcels are pulled right up to that deadline, so a list researched a week out is not the list that sells.
The sale is an auction of the property itself. The highest bidder at or above the minimum wins. Counties gate bidding behind a refundable deposit funded days ahead, and winning bids are due in full on the deadline the county terms set, usually within days of the close. A winner who does not pay forfeits the deposit and the parcel returns to inventory.
The buyer receives a tax deed, and unsold parcels come back as reoffers. The tax collector issues a tax deed under Section 3712; there is no redemption after the sale. A parcel that draws no bid at the minimum is not finished: under Section 3698.5 the tax collector may offer it again, including at a reduced minimum, and Chapter 8 (Section 3771 and following) routes some properties to public agencies and nonprofits instead. The leftover channel in California is a second, cheaper auction, and it is part of the pricing decision on the first one.

How bidding works in San Joaquin County

Create a Bid4Assets account and register for the San Joaquin County sale, filling out vesting information before you are allowed to access the deposit instructions. Registration is free on Bid4Assets, but the deposit below is required to bid, and bidders must be at least 18 years old. Questions on registration and bidding go to Bid4Assets at (877) 427-7387 or customerservice@bid4assets.com, and county questions to (209) 468-2133 or tax@sjgov.org.

The deposit gate is real. California online sales close registration and deposit funding days before the auction opens, and an unfunded deposit cannot bid. The deadline that decides whether you are in the sale is the deposit deadline, not the auction date.
Payment clocks are short and enforced. Winning bids come due on the county's deadline, often within days of the close, and a missed payment forfeits the deposit. Fund the maximum bid before the auction opens, not after it closes.

Terms: what a bid actually costs

Deposit, San Joaquin County	The deposit is $5,000 plus a $35 non refundable Bid4Assets processing fee, paid to Bid4Assets by certified check or wire, and it must be received no later than 1:00 p.m. Pacific Time one week prior to the tax sale. Make the deposit well in advance of the auction to ensure eligibility. If you are not the winning bidder, the deposit is automatically refunded within 10 business days of the close of the auction, by check to the name and address in your Bid4Assets profile for check or wire deposits.
Payment, San Joaquin County	Successful bidders must settle with Bid4Assets by certified check or wire. A documentary transfer tax of $0.55 per $500 of the sales price is collected in addition to the bid, plus a $35 administrative fee per parcel purchased, charged by Bid4Assets. For the 2026 sale, deed vesting information was required by Monday, March 16, 2026 and full payment was required by Thursday, March 19, 2026; the 2027 payment deadline was not published as of November 9, 2026. If settlement is not completed by the payment deadline, the deposit is forfeited and the bidder is banned from future tax sales. All sales are final.
What is sold	The property itself, by tax deed. California sells no tax liens or certificates to the public at any stage: the Chapter 7 auction is the whole event, and the deed is what the winning bid buys.
Minimum bid	The minimum price under Section 3698.5(a), built from the delinquent taxes, penalties and costs the code specifies. At a first offering the floor is the full statutory amount, not a market estimate. Reoffers under Section 3698.5 can carry a lower minimum, which is why the same parcel can be two very different buys in two rounds.
Redemption	The owner may redeem until the close of business on the last business day before the sale begins. After the sale there is no redemption, by anyone, at any price. Everything about a California bid is priced on that hard stop.
The deed	A tax deed issued by the tax collector under Section 3712. It conveys the title described in the statute, free of most liens and encumbrances, with statutory exceptions (liens of public agencies with priority and recorded easements among them). It is not a title insurance policy; title work after the sale is the buyer's job.
Costs on top of the bid	The deposit mechanics and payment deadline in the county terms, plus documentary transfer tax and recording charges as the county publishes them, and current year taxes the sale terms assign to the buyer.

Reoffers and the redemption problem

San Joaquin reoffers unsold parcels at a published second sale date, which was May 27 to May 28, 2026 for the March 2026 sale, and the same pattern is expected after March 2027, though no reoffer date was published as of November 9, 2026. The real leftover story here is redemption: 104 of 125 parcels in the March 2026 results were redeemed before the sale, 15 were removed, and only 2 drew no bids, so the March 2027 list will almost certainly shrink in the same way before bidding opens. The county reserves the right to reject any bid, withdraw a property at any time before or during the sale, or cancel a sale at any point prior to the issuance of the deed.

Before you bid

Work the list twice. Redemption pulls parcels until the close of business on the last business day before the sale. The list a county publishes at notice is the research list; the list that actually sells is shorter. Re-check the morning the auction opens.
As is, and the deed is not a policy. No interior access, occupants may be in place, and the tax deed's statutory exceptions leave title homework behind the sale. Drive the property, read the county disclosures, and budget the title and cleanup work.
Price the reoffer before the first sale. Parcels that draw no bid at the minimum return under Section 3698.5, sometimes at a reduced minimum. Decide in advance whether you are a first round buyer at the statutory floor or a reoffer buyer waiting for the second price.
