Private Activity Bonds: Financing Projects With Public Benefits

Private Activity Bonds: Financing Projects With Public Benefits

4 Min.

Private Activity Bonds (PABs) are issued by State or Local Governments to finance projects with public benefits, and they offer tax benefits if they meet specific criteria. This article provides an overview of PABs, their uses, tax treatment, and eligibility criteria.

Basics of Private Activity Bonds

Private Activity Bonds are financial instruments issued by State or Local Governments or authorities on behalf of these entities. They serve the purpose of financing projects that offer specific financial benefits to qualified ventures. While PABs might sound like a government initiative, they are primarily used to fund projects driven by private entities, and the government typically does not pledge its credit for these bonds. Private Activity Bonds are sometimes referred to as conduit bonds due to their role as intermediaries.

Understanding PABs

PABs are essentially municipal bonds that aim to attract private investment for projects that carry public benefits. However, these bonds come with stringent criteria that determine the eligibility of the projects they can finance. Here are some of the qualified projects that may be financed through PABs:

  1. Student Loans: PABs can be used to fund and refinance student loans, making education more accessible.
  2. Airports: Projects related to airports, such as expansion or modernization, can benefit from PAB financing.
  3. Private Universities: Private universities can use PABs to fund infrastructure improvements and expansions.
  4. Hospitals: Building or expanding healthcare facilities is a common use for PAB financing.
  5. Affordable Rental Housing: PABs can support the construction of affordable rental housing units.
  6. Mortgage Provision for Lower-Income Borrowers: These bonds can help lower-income borrowers access mortgages.
  7. And more: Various other projects that serve public interests are eligible for PAB financing.

However, it's essential to note that not all projects can benefit from PABs. The proceeds from PABs cannot be used to finance projects such as airplanes, specific health club facilities, gambling facilities, stadiums, golf courses, oil refineries, or liquor stores. These exclusions help maintain the tax-exempt status of PABs.

Benefits of PABs

One of the primary advantages of PABs is that they can reduce financing costs for projects by providing an exception from federal taxes. State and local governments issue PABs on behalf of private companies and nonprofit organizations, enabling them to borrow at lower interest rates compared to corporate bonds or bank loans. This, in turn, attracts businesses and labor to regions, ultimately creating a public benefit.

However, it's crucial to remember that PABs generally pay taxable interest unless they receive specific exemptions from the federal government.

Tax Treatment of Private Activity Bonds

Under Section 103(a) of the Internal Revenue Code (IRC), interest earned on private activity bonds is generally not excluded from gross income, unless the bond qualifies as a "qualified bond." The Tax Reform Act of 1986 introduced changes, subjecting interest from private activity bonds to the Alternative Minimum Tax (AMT). However, it's worth noting that hospital and non-profit college bonds are exceptions to this rule. Due to this tax treatment, yields on private activity bonds are often higher compared to other bonds.

Criteria for Private Activity Bonds

According to Section 141 of the IRC, a municipal bond is categorized as a private activity bond if it meets specific criteria:

  1. More Than 10% for Private Business: If over 10% of the proceeds from a bond issue are used for any private business, and if more than 10% of the sale proceeds of the issue are secured by a private business property, the bond will be considered a private activity bond.
  2. Loans to Non-Governmental Borrowers: A municipal bond can also be classified as a private activity bond if the amount of proceeds used to make loans to non-governmental borrowers exceeds 5% of the proceeds or $15 million, whichever is less.

These criteria help differentiate between bonds that serve public purposes and those primarily benefiting private businesses.


Private Activity Bonds play a vital role in financing projects that offer public benefits while attracting private investment. These municipal bonds, issued by State and Local Governments, come with specific eligibility criteria to ensure they support projects with genuine public interest. PABs provide tax benefits, although some are subject to the Alternative Minimum Tax. Understanding the tax treatment and eligibility criteria is essential for those involved in PAB-related financing and investment decisions. Whether it's funding student loans, expanding airports, supporting affordable housing, or other projects, PABs serve as a valuable tool in promoting public well-being and economic growth.
