Marin County, CA tax sales

County offices

County notes

• •County seat San Rafael. The Marin County Department of Finance states it "serves as the County's auditor, controller, tax collector, treasurer, and public administrator," so the Tax Collector sits inside Finance rather than in a standalone office.
• •Tax Collector office hours are Monday to Friday, 9:00 am to 4:30 pm.
• •The auction platform is Public Surplus. The county links to the organization page titled "County of Marin - Tax Sale," which lists no current auctions, consistent with the county saying no auction is scheduled.
• •Investors should treat Marin as a low-volume, irregular deed market. Recent public auctions on record are March 2024, 2017, and 2014.
• •Minimum bid is set at no less than redemption amount plus an estimate of current year taxes and costs, so opening prices track back taxes rather than market value.
• •Sealed bid sales are a separate track for unusable parcels and are restricted to contiguous owners or easement or undivided-interest holders. Bid forms must be issued by the Marin County Tax Collector's office and submitted with certified funds.
• •The county cites California Revenue and Taxation Code sections 3692, 3692.3, 3712, 3725, and 4675 for sale conditions, surviving encumbrances, the one-year challenge window, and excess proceeds claims.
• •For questions on redemption, the proposed sale, or excess proceeds the general information page directs callers to (415) 473-6133. The sealed bid page lists (415) 473-6909 for sealed bid questions, and the property list page lists 415-473-6154 for document access.

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.California Revenue and Taxation Code 3707 - right of redemption terminates at close of business on the last business day before the saleCal.

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.California Revenue and Taxation Code 3706 - sale at public auction to the highest bidder, no bid below the approved minimum priceCal.

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.California Revenue and Taxation Code 4675 - claims for excess proceeds within one year of recordation of the tax deed, and claim priorityCal.

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.California Revenue and Taxation Code 3712 - the deed conveys title free of encumbrances existing before the sale, with listed exceptionsCal.
