Investing in tax liens can be an appealing opportunity for California investors seeking strong returns. When property owners fall behind on their property taxes, counties can place a lien on the property and sell it at auction to recover the unpaid balance. Investors who purchase these liens gain the right to collect the delinquent taxes plus interest. In rare cases, they may even acquire the property if the debt remains unresolved. While this strategy can generate meaningful profits, it also requires a clear understanding of California’s legal framework, auction process and financial risks.
For help with your own portfolio, whether related to real estate or not, consider talking to a financial advisor.
How Tax Lien Investing Works in California
Tax lien investing can allow investors to potentially earn significant returns. When property owners in California fail to pay their property taxes, counties can sell tax liens at auction to recoup the unpaid taxes. Investors who purchase these liens pay the delinquent tax amount and, in return, receive the right to collect the taxes owed plus interest.
Tax lien auctions are typically held online, making it accessible for investors across the state and beyond. Counties will announce these auctions, providing details about the properties and the unpaid taxes. Investors must register in advance, often providing a refundable deposit to participate. During the auction, the highest bidder wins the lien certificate, which grants them the right to collect the debt from the property owner.
Another important aspect of tax lien investing in California is the redemption period. After the auction, property owners have a set period, typically five years, to repay the delinquent taxes along with any interest and penalties. If the owner redeems the lien within this period, the investor receives their initial investment plus the accrued interest. The interest rate is determined by the state and can vary, providing potentially lucrative returns for the investor.
If the property owner fails to redeem the lien within the redemption period, the investor can initiate foreclosure proceedings. This process allows the investor to take ownership of the property, often at a fraction of its market value. However, this outcome is relatively rare as most property owners will redeem their liens to avoid losing their property. Nonetheless, the possibility of acquiring property adds an additional layer of potential profit for investors.
Ways to Invest in Tax Lien Properties in California
With careful planning and due diligence, tax lien investing can be a profitable addition to your investment portfolio. Here are three common ways you could get into investing in these properties.
- Online tax lien auctions: Counties across the state frequently hold these auctions to sell liens on properties with unpaid taxes. Investors can register online, review the list of available properties, and place bids.
- Buy directly from county offices: Some counties allow investors to buy tax liens that were not sold during the initial auction. By contacting the county tax collector’s office, investors can obtain a list of available liens and make purchases directly.
- Networking with real estate professionals: Building a network with real estate professionals, including realtors, property managers and other investors, can provide valuable insights and opportunities for investing in tax lien properties. These professionals often have access to information about upcoming auctions and available liens.
Tips for Tax Lien Investing in California

Tax lien investing in California offers attractive returns, but it requires a strategic approach. Here are five essential tips to help you reach your goals:
- Research the property: Before investing in a tax lien, thoroughly research the property in question. Understand its market value, location and any existing liens or encumbrances.
- Understand the legal process: Familiarize yourself with California’s specific legal requirements for tax lien investing. Each county may have different rules and procedures for auctions, redemption periods and foreclosure processes.
- Evaluate the redemption period: California typically offers a five-year redemption period during which the property owner can repay the owed taxes plus interest. Evaluate the likelihood of redemption and the interest rate offered to determine the potential profitability of your investment.
- Be prepared to pay the delinquent taxes: Register for county auctions in advance, review the list of available properties and prepare to bid. Winning bidders must pay the delinquent taxes to obtain the lien certificate.
- Seek professional guidance: Consult with a financial advisor or real estate professional who specializes in tax lien investing. They can provide valuable insights, help you navigate the process and ensure that you make informed decisions.
California-Specific Rules and Regulations
California has unique rules that set its tax lien process apart from other states. As such, it’s important for investors to understand how local regulations work before participating in an auction.
One of the most notable differences is California’s five-year redemption period, which is longer than the redemption timelines in many other states 1 . During this period, property owners can repay their delinquent taxes, interest and penalties to reclaim their property. For investors, this means returns may take longer to materialize, and the likelihood of acquiring the property through foreclosure is relatively low.
Another important distinction is that counties in California may follow slightly different procedures for tax lien sales, including registration requirements, bidding formats and auction schedules. Some counties conduct premium bid auctions, where investors compete by offering higher amounts above the base tax lien, while others may use alternative formats. Investors should review each county’s specific auction guidelines so they know how bidding works and what deposits or documentation may be required.
California also limits the interest and penalties applied to redeemed liens. Interest rates are set by state law and may be adjusted periodically, which means potential returns can vary depending on when the lien is purchased.
Additionally, California does not allow for the sale of liens with preexisting environmental hazards or certain encumbrances, and some counties offer detailed property information to help investors avoid these risks.
Bottom Line

Buying tax liens in California can offer investors a unique investment opportunity with the potential for significant returns. By understanding the auction process, researching properties thoroughly and being aware of the legal and financial implications, investors can navigate this market effectively. It’s important to stay informed about county-specific regulations and redemption periods to maximize profitability and minimize risks.
