Alameda County Tax Lien Sale: Bidding, Fees, and Tax Deeds

An Alameda County tax lien sale is actually a tax deed sale: California does not sell liens against delinquent property, it sells the property itself, and the winning bidder receives a recorded deed once payment clears.¹ Alameda County runs these sales online through Bid4Assets, and the next auction is scheduled for March 20–23, 2026.²

When and Where the Auction Happens

Bidding for the March 2026 sale opens on March 20 at 8:30 AM Pacific Time and closes on March 23. Individual lots can close at staggered times, and late bids in the final minutes trigger an extension so other bidders have a chance to respond.² If you plan to compete on more than one parcel, watch the auction window closely.

Everything happens on Bid4Assets. The county does not run an in-person sale, and there is no backup way to bid if you miss the registration deadline.

Registering and Placing Your Deposit

You need a Bid4Assets account with completed vesting information before you can even see the deposit instructions, so this is not a last-day task. Vesting is how you want to hold title, and whatever name you enter during registration is the name that will appear on the recorded deed.²

A refundable $5,000 deposit plus a non-refundable $35 processing fee are required to bid. For the March 2026 sale, the deposit must be in by 1:00 PM Pacific Time on March 17, 2026. One deposit lets you bid on any number of parcels, but you must have enough money ready to pay for every property you win. Deposits for non-winning bidders are returned by eCheck within 10 business days after the auction closes.²

The platform uses proxy bidding. You enter your maximum, and the system bids on your behalf in small increments to keep you ahead, up to that limit. Properties sell strictly as-is, with no interior inspection and no warranties about condition, zoning, boundaries, or legal status. Research every parcel independently before you bid.

How Minimum Bids Are Set

Each property has a minimum bid built from what it would cost the owner to redeem: defaulted taxes, delinquent and redemption penalties, a redemption fee, publishing and processing costs, administrative costs, and any outstanding property tax postponement loan balance. The minimum has nothing to do with market value. Some Alameda County minimums have opened as low as a few hundred dollars, usually on small or difficult-to-develop lots. There is no hidden reserve above the published starting amount.

Fees Added on Top of Your Winning Bid

Settlement instructions arrive by email after the auction closes. For the March 2026 sale, full payment is due by 1:00 PM Pacific Time on March 25, 2026, with no exceptions.² The settlement figure is not just your bid. Several charges get added:

Documentary transfer tax of $0.55 per $500 of the purchase price, equivalent to $1.10 per $1,000.³
City transfer tax where applicable. Oakland charges between $10 and $25 per $1,000 depending on the sale price, Berkeley charges $15 to $25 per $1,000, and Hayward charges $8.50 per $1,000.⁴
A recording fee of $17 per parcel, which can rise with the page count of the deed.
A $35 administrative fee per parcel won.²

The city transfer taxes are what catch new bidders off guard. On a $500,000 Oakland property, that line alone can run $7,500 to $12,500 depending on the price bracket. Build these numbers into your maximum bid before the sale, not after you’ve won.

If a winning bidder fails to pay by the deadline, the county keeps the $5,000 deposit. California law does not allow the county to simply roll the property over to the next-highest bidder, so defaulting carries real consequences.²

What the Tax Deed Wipes Out and What Survives

Once payment clears, the Treasurer-Tax Collector issues a tax deed and the Clerk-Recorder records it. The deed clears most prior encumbrances, including previous mortgages, judgment liens, and the delinquent tax liens that drove the sale. Several categories survive and transfer to you as the new owner:

Taxes and special assessments that become payable on the secured roll after the sale date.
Liens held by any taxing agency that did not consent to the sale.
All easements, including prescriptive easements, and water rights with separately held title.
Federal IRS liens that are not discharged under federal law, even when the tax collector properly notified the IRS.
Unpaid Mello-Roos special taxes under the Community Facilities Act, if not satisfied by the sale proceeds.
Unpaid assessments under the Improvement Bond Act of 1915, under the same rule.⁵

The IRS liens and Mello-Roos obligations are the ones that can genuinely cost you money after you’ve won. Before bidding, check whether the parcel sits in a Mello-Roos community facilities district and whether any federal tax liens have been recorded against the property or its former owner. The county will not do this research for you.

Getting Insurable Title After the Sale

The deed makes you the legal owner, but most title insurance companies will not issue a policy based on a tax deed alone. Insurers treat tax sales as risky because of possible procedural defects in notice, unknown heirs, or unresolved encumbrances. To get marketable title that a lender or future buyer will accept, you will likely need to file a quiet title action.

A quiet title action asks a judge to confirm your ownership and extinguish competing claims. It typically takes several months and requires serving notice on anyone who might have had an interest in the property. Attorney fees generally range from a few thousand dollars on an uncontested case to significantly more if someone contests the deed. If you plan to resell or refinance, budget this cost into your total investment.

If You’re the Owner Facing a Sale

You can stop the sale by paying all delinquent taxes, penalties, and costs in full, but the window closes at the end of business on the last business day before the auction begins. Mailed payments must physically arrive at the tax collector’s office before that cutoff; postmark dates do not count.⁶

Once that deadline passes, all legal and equitable interest in the property is gone. California has no post-sale redemption period. The right to redeem revives only if the property fails to sell at auction, or if the tax collector approved a credit transaction with the winning bidder and the bidder never paid in full by the required date.⁶

Claiming Excess Proceeds

When a property sells for more than the delinquent taxes and costs owed, the county holds the surplus as excess proceeds. Former owners and other parties with a recorded interest in the property at the time of sale can file a claim. The deadline is one year from the date the county records the tax deed to the purchaser, and the claim must be postmarked on or before that date.⁷

The claim must include whatever information and proof the county’s board of supervisors requires to verify the claimant’s interest. If a third party files on your behalf, such as a claims recovery company, state law requires them to disclose the amount and source of the proceeds and tell you that you can file directly with the county at no cost.⁷ Those companies often charge substantial fees for a filing former owners can handle on their own.

When multiple parties file, proceeds are distributed by legal priority. A former owner with equity will typically have the strongest claim, but recorded lienholders can also recover depending on the surplus available and their position in the priority chain.
