Tax Lien Certificate


A Tax Lien Certificate is a legal document that grants the holder the right to collect unpaid property taxes, plus interest and penalties, from a delinquent property owner. It is issued by a local government when a property owner fails to pay their property taxes on time. In exchange, the certificate purchaser pays the owed tax debt, and the property owner is obliged to pay them back with interest.


The phonetic pronunciation of “Tax Lien Certificate” is: tæks liːn sərˈtɪfɪkət

Key Takeaways

  1. Tax Lien Certificates are a type of investment where an investor purchases the lien on a property for the unpaid taxes. This allows the property owner to pay their overdue taxes and the investor typically earns a high interest rate on their investment.
  2. Investing in Tax Lien Certificates can be a profitable venture, as the interest rates can range from 8% to 50%. However, it also carries risks, such as the property owner defaulting on their loan or potential issues with the condition of the property.
  3. In order to invest in Tax Lien Certificates, an investor must participate in tax lien auctions, which may be held online or in person. Research and due diligence are crucial to success in these auctions, as the investor needs to understand the value of the property and potential risks associated with each certificate.


A Tax Lien Certificate is important in the world of business and finance, as it represents a legal claim by a government authority against a property due to the owner’s unpaid taxes. These certificates offer a secure and potentially lucrative investment opportunity for investors, who essentially pay the delinquent taxes on behalf of the property owner. In return, the investor earns the right to collect interest on the tax debt, often at a higher rate than traditional investment vehicles. Furthermore, it encourages property owners to promptly pay their due taxes, helping the government continue to fund essential public services and foster a healthy financial environment for the community. Thus, Tax Lien Certificates play a crucial role in safeguarding both public and private interests in the finance sector.


A tax lien certificate serves as an essential financial instrument primarily used by municipalities and governmental bodies to recover unpaid property taxes. As property owners are legally obliged to pay taxes on their properties, failure to do so can result in the local government issuing a tax lien – a claim on the delinquent property to secure the payment of taxes. Consequently, in an auction, tax lien certificates are sold off to investors, who pay the owed taxes on behalf of the property owners.

The purpose of these certificates is to support local authorities in quickly raising the necessary funds for public expenditures, such as infrastructure, education, and public services, which would otherwise struggle due to delayed tax payments. An investor who purchases a tax lien certificate effectively becomes a lien holder and earns the right to collect the owed taxes, along with any interest and penalties, directly from the property owner within a specified timeframe, as dictated by the respective laws. The interest rates on the certificates offer an attractive return on investment, hence making tax liens a sought-after investment option.

In a worst-case scenario where the property owner defaults on tax lien repayments, the lien holder may be entitled to foreclose the property, potentially securing a valuable asset at below market value. This arrangement not only assists governmental bodies in maintaining a steady revenue stream but also provides a unique and relatively low-risk investment opportunity for wisely-executed tax lien investments.


Example 1: John’s Property Tax LienJohn owns a residential property in Arizona, but he failed to pay his property taxes this year. As a result, the local government placed a tax lien on his property. An investor named Mary bought the tax lien certificate during a public auction. Mary paid the outstanding tax amount plus any interest and penalties. In return, she earned the right to collect the debt from John along with interest. If John fails to pay Mary within the redemption period (usually between 1-3 years), she can foreclose the property and take ownership.

Example 2: Downtown Commercial BuildingA commercial building located in a downtown area has a tax lien placed on it due to unpaid property taxes. The total amount of unpaid taxes is $50,000. An investor, Robert, decides to purchase the tax lien certificate at an auction and pays the $50,000 to the local government. The property owner has a redemption period to pay back Robert, and during this time, Robert earns interest on his investment. If the property owner fails to pay Robert within the redemption period, Robert has the right to foreclose on the property and take ownership, potentially making a significant profit.

Example 3: Abandoned PropertyAn abandoned property in a rural area has a tax lien due to years of accumulated unpaid property taxes, which now amount to $10,000. Sarah, a real estate investor, purchases the tax lien certificate at a public auction for the amount owed. After the redemption period passes and the previous property owner fails to repay the debt, Sarah has the right to initiate foreclosure proceedings. Once she gains ownership of the property, she can rehabilitate the property and sell it at a profit or rent it to generate passive income.

What is a Tax Lien Certificate?

A Tax Lien Certificate is a legal document issued by a government agency as a claim against a property due to unpaid property taxes. The certificate grants the holder the right to collect the owed taxes, including interest, from the property owner.

How do Tax Lien Certificates work?

When a property owner fails to pay property taxes, the government places a tax lien on the property. The government then auctions off the tax lien certificates to investors, allowing them to pay the owed taxes on behalf of the delinquent property owner. In return, the investor receives the right to collect the taxes, including interest and penalties, from the property owner.

How do I invest in Tax Lien Certificates?

To invest in Tax Lien Certificates, you must first research the rules and regulations in the municipality or county you are interested in investing in, as they may vary. Then, you can attend tax lien auctions held by the local government or purchase tax liens online if available. Keep in mind that investing in Tax Lien Certificates requires a considerable amount of due diligence and research on the properties involved.

What are the risks associated with investing in Tax Lien Certificates?

Although Tax Lien Certificates may offer potentially high returns due to the interest rates, they also carry risks. The property owner may have financial or legal problems that make it difficult to collect the taxes owed. Additionally, if the property owner does not pay the taxes and the property becomes subject to foreclosure, there may be hidden costs or other issues with the property that decrease its value.

What are the potential returns on investing in Tax Lien Certificates?

The potential returns on investing in Tax Lien Certificates can be quite high due to the interest rates charged on the outstanding taxes. Interest rates can range from 12% to over 36% per annum, depending on the jurisdiction. However, it is important to remember that these returns are not guaranteed, and the investment carries risks.

How long will it take to collect on my Tax Lien Certificate investment?

The length of time it takes to collect on a Tax Lien Certificate investment can vary based on several factors, including the property owner’s financial situation and the jurisdiction’s redemption period. The redemption period is the time frame during which the property owner can pay their owed taxes, including interest and penalties, to clear the lien. This period can range from a few months to several years.
