How to Buy Tax Deeds in California: A Complete Investor Guide

How California tax deed sales work

California is a tax deed state, not a tax lien state. Counties do not sell interest-bearing lien certificates. Instead, when property taxes go unpaid, the county tax collector eventually sells the property itself at public auction, and the winning bidder receives a tax deed conveying title.

The legal engine behind this is the "power to sell." Under California Revenue and Taxation Code, most residential and commercial property that remains tax-defaulted for five years (three years for certain non-residential and nuisance-abated parcels) becomes subject to the tax collector's power to sell. Only then can the parcel be offered at a tax-defaulted land sale.

The five-year default timeline

Understanding the timeline matters because it is also the owner's redemption window. Property does not go to auction the first year taxes are missed.

Here is the general sequence most California counties follow:

• •Taxes become delinquent and the parcel is declared "tax-defaulted" after the fiscal year closes.
• •Redemption penalties accrue at 1.5% per month (18% per year) on the defaulted amount, plus fees.
• •After five years of continuous default, the property becomes subject to the power to sell.
• •The tax collector schedules a public auction, usually online, and gives statutory public notice to the owner and lienholders.
• •The owner can redeem by paying all taxes, penalties, and costs up until the close of business on the last business day before the auction.

Where and how the auctions run

Most California counties, including large ones like Los Angeles, San Bernardino, Riverside, and Sacramento, run their tax-defaulted sales online through third-party auction platforms. Smaller counties may still hold in-person or sealed-bid sales.

To participate you typically register on the county's chosen platform, submit a refundable deposit (often a few thousand dollars or a percentage of expected bids), and agree to the county terms. Auctions are usually held once a year, though counties can hold reoffer or sealed-bid sales for parcels that did not sell.

The opening bid generally covers the defaulted taxes, penalties, and costs of sale. Winning bids above that amount can create excess proceeds, which the former owner or lienholders may later claim.

What you actually get and what you don't

A California tax deed conveys the county's interest in the parcel. In most cases the sale extinguishes the defaulted property tax lien and many junior liens, but it does not automatically give you clean, insurable title.

Certain encumbrances can survive a tax deed sale. These commonly include IRS federal tax liens (which carry a 120-day federal redemption right after the sale), other government liens, certain special assessments and bonds, and easements. Title companies also generally will not insure a tax-deed title until a quiet title action or a statutory waiting period clears the record.

Redemption and the one-year rescission risk

Once the auction closes and the deed records, the former owner's ordinary right of redemption ends. That is a key difference from tax lien states, where owners often have a long post-sale redemption period.

However, California law allows a tax deed to be rescinded in limited circumstances, such as a defect in the sale process or an owner who was not properly noticed. A rescission action generally must be brought within one year of the recording of the tax deed. This is why experienced investors treat the first year after purchase as a period to verify notice was proper before making large improvements.

Due diligence before you bid

Because you usually cannot inspect the interior and the sale is final, research is everything. Before bidding on any California parcel, check the following:

• •Confirm the assessor parcel number, legal description, and that the parcel is a usable lot rather than a sliver, easement, or landlocked strip.
• •Search for surviving liens, especially IRS federal tax liens and government or special-assessment liens.
• •Check zoning, code violations, and whether structures are habitable or condemned.
• •Review FEMA flood zones and environmental hazards that affect value and financing.
• •Estimate quiet title costs and time, since you will likely need it to sell or insure the property.
