When it runs
Spring, with a follow-up re-offer in June. In 2026 the county Tax Sales page listed the main Tax Defaulted Auction for May 8 to May 11, 2026, and a second event on Bid4Assets for June 12 to 15, 2026. The Bid4Assets storefront for that June event is titled a Tax Defaulted Properties Re-offer Auction; it opened June 12, 2026 at 11:00 AM ET (8:00 AM PT) and closed June 15, 2026, with closing times that varied by parcel. Both 2026 events have ended. Confirm the next year's dates on the county Tax Sales page before planning around them.
Registration and deposit

Bidding is online through Bid4Assets. Create a free Bid4Assets account, then post the deposit the county requires. For the June 2026 re-offer the storefront states: "A single $2,000 deposit (plus a $35 non-refundable processing fee) is required to participate in the County of Tuolumne Tax Sale," and that "for Tuolumne County, all prospective bidders MUST fill out their vesting information before they are allowed to access the deposit instructions." That deposit had to reach Bid4Assets no later than 4:00 PM ET (1:00 PM PT) on Monday, June 8, 2026, four days before bidding opened. Deposits from non-winning bidders are refunded by eCheck within 10 business days after the auction closes. The settlement deadline for that sale was June 18, 2026 at 4:00 PM ET (1:00 PM PT). The county also links Bid4Assets' "How to Participate in County Tax Sales" guide and the State Controller's bidder information page.

Sale format and venue
California deed state: Tuolumne sells the property itself, not a lien, and the Treasurer & Tax Collector runs the auction online on Bid4Assets. There is no in-person bidding component advertised on the county page. The county cites Revenue and Taxation Code 3691 and explains that property with unpaid current or prior year taxes as of July 1 is declared tax defaulted, and that parcels still unpaid after five years may be sold at a tax auction; the owner can stop the sale by paying in full before June 30 of the fifth year or by starting an installment plan before the sixth year of delinquency. The county states the sale's purpose is to return tax defaulted property to the tax rolls, either by selling it or by forcing redemption. Buyer beware language is explicit: all parcels are sold as is, no warranty of any kind, no guarantee of access or building permits, the county assumes no liability for other liens, encumbrances or easements whether recorded or not, and ALL SALES ARE FINAL with no refund for inadequate research. The June 2026 event was a re-offer of 4 properties with bids starting as low as $500 and no reserve, which is a useful signal that unsold May parcels come back at a lower minimum. The Tax Sales page also hosts excess proceeds claim forms and estimated proceeds sheets for the 2018, 2019, 2021, 2022, 2024, 2025 and 2026 sales. The county page listed two 2026 dates: May 8 to May 11 for the main auction and June 12 to 15 for the re-offer.

Tuolumne County tax sale list and auction calendar

For Tuolumne County tax sale 2026 searches, use the county-run sources below rather than a copied parcel list, and confirm the parcel, registration cutoff, deposit, and payment deadline against the county before you bid. If the parcels on this list are vacant land rather than houses, what buying land at a tax sale hands you is the place to start.

  1. Confirm the advertised parcel list

    Use Property Listing (2026 Webpage Defaulted List, PDF) as a starting reference. Check which sale or list it covers; a Lands Available or office information page is separate from an auction parcel list. Ask the sale office for the advertised parcels for the auction you plan to attend.
  2. Register to bid

    Bidding is online through Bid4Assets. Full requirements are in the sale card above.
  3. Sale day

    Spring, with a follow-up re-offer in June. Bidding runs on Bid4Assets; check posted sale dates, registration status, and bidding windows there.
  4. Confirm with the office

    If public notices disagree, call the county office that runs the sale before bidding. Do not rely on a third-party list for final parcel status.

Before you bid in Tuolumne County

  1. Confirm the parcel list before pricing

    Open Property Listing (2026 Webpage Defaulted List, PDF). Confirm whether this reference contains the auction parcels or covers a different list. Get the advertised parcel list from the county before you price a bid, and recheck it before the sale.
  2. Confirm registration and deposit

    Bidding is online through Bid4Assets. Create a free Bid4Assets account, then post the deposit the county requires. For the June 2026 re-offer the storefront states: "A single $2,000 deposit (plus a $35 non-refundable processing fee) is required to participate in the County of Tuolumne Tax Sale," and that "for Tuolumne County, all prospective bidders MUST fill out their vesting information before they are allowed to access the deposit instructions." That deposit had to reach Bid4Assets no later than 4:00 PM ET (1:00 PM PT) on Monday, June 8, 2026, four days before bidding opened. Deposits from non-winning bidders are refunded by eCheck within 10 business days after the auction closes. The settlement deadline for that sale was June 18, 2026 at 4:00 PM ET (1:00 PM PT). The county also links Bid4Assets' "How to Participate in County Tax Sales" guide and the State Controller's bidder information page.

  3. Check the state rules that change the bid

    Read the California due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth. Which liens survive is state law, so read what survives a tax deed in California before you price the title work.
  4. Set a walk-away number

    Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.

California rules

Redemption
Tax-defaulted property may be redeemed until the right of redemption is terminated (section 4101). That right terminates at the close of business on the last business day prior to the commencement date of the tax sale, and the start of the auction counts as the sale date no matter when bidding closes. A redemption payment sent by mail must be received in the tax collector's office before that deadline. California has no post-sale redemption period: once the auction opens, a record owner who has not redeemed loses all legal and equitable interest in the property. Two situations revive the right of redemption. The right revives if the property is not sold, and it revives on the next business day if the tax collector approved a credit sale and the buyer did not pay in full by the deadline the tax collector set.
Deed deposit
The tax collector may require a deposit and must give public notice before the sale of its amount, payment method, and due date, and of whether it is a condition of bidding or applies toward the purchase price. On a sale the tax collector approves as a deferred-payment transaction, the deposit may be $5,000 or 10 percent of the minimum bid price, whichever is greater. Counties set the specific figure, so confirm it on the county page or auction platform.
Surplus proceeds
Sale proceeds first cover statutory distributions, then taxes, assessments, and county costs. Anything left is excess proceeds held in the delinquent tax sale trust fund. A party of interest may file a claim at any time before one year after the tax collector's deed to the purchaser is recorded. Distribution runs first to lienholders of record before the tax deed was recorded, in order of their priority, then to persons with title of record. Excess proceeds not claimed within that year may be transferred to the county general fund.
Governing statute
Cal. Rev. & Tax. Code, Division 1, Part 6 (sections 3351 to 3972)

What the deed conveys: The deed conveys title free of encumbrances existing before the sale, subject to listed exceptions that survive: taxes and assessment installments not yet payable, liens of taxing agencies that did not consent to the sale, certain special assessments not included in the redemption amount, easements and recorded restrictions, recorded irrevocable offers of dedication, unpaid Improvement Bond Act of 1915 assessments not satisfied from the proceeds, federal IRS liens not discharged by the sale, and unpaid Mello-Roos special taxes. A tax deed is not marketable or insurable title on its own, and most buyers file a quiet title action before resale. See the due diligence guide.
