Grant anticipation notes are short-term municipal debt instruments that let a state or local government borrow against a grant it has been formally promised but has not yet received. The government issues notes to investors, spends the proceeds on the project right away, and repays note holders once the grant money actually arrives. The pledged grant is the security, which is what distinguishes these notes from general-purpose municipal borrowing.
How the Borrow-Against-a-Grant Mechanic Works
Large grants rarely land in a government’s bank account on the day they are approved. A state might win approval for a federal highway grant in January and not see the first reimbursement check until the following year. In the meantime, contractors have to be paid and materials have to be ordered. That timing gap is exactly what a grant anticipation note is built to close.
The structure is straightforward. The issuer sells notes in the municipal bond market at a stated interest rate and pledges a specific grant as the source of repayment. Investors are essentially lending against the government’s grant receivable. When the grant funds show up, the issuer applies them to pay off principal and interest.
Because the security is a narrow, identified revenue stream rather than the issuer’s full taxing power, the pricing turns on the reliability of that particular grant. Most structures include a covenant that the issuer will pursue collection of the grant and apply the proceeds exclusively to the notes, will not pledge the same revenue elsewhere, and will deposit the incoming funds into a segregated trust account so they flow directly to note holders rather than through the general fund. Some deals add a subordinate pledge of other available funds as a backup if the grant is delayed or reduced, but that secondary source is not what drives the credit.
Traditional short-term GANs generally mature within three months to three years, timed to line up with the expected grant receipt. Bridge the gap, retire the debt.
GARVEEs: The Dominant Form of Grant Anticipation Financing
By far the most widely used version of this instrument is the Grant Anticipation Revenue Vehicle, or GARVEE. GARVEEs are bonds or notes backed by future federal-aid highway funding under Title 23 of the U.S. Code. Congress authorized the approach in 23 U.S.C. ยง 122, which allows federal reimbursement not just for construction costs but also for the debt service on bonds issued to fund eligible highway projects.1Office of the Law Revision Counsel. 23 U.S. Code 122 – Payments to States for Bond and Other Debt Instrument Financing
That reimbursement rule is the unusual feature. Federal highway grants ordinarily reimburse the cost of building roads and bridges. Under Section 122, the federal government also reimburses interest payments, principal retirement, issuance costs, and insurance costs on the bonds themselves.2Federal Highway Administration. Grant Anticipation Revenue Vehicle (GARVEE) Bonds A state can build a highway now and use annual federal-aid apportionments to cover debt service over many years, spreading a large capital cost across the facility’s useful life.
That is why GARVEEs, unlike traditional short-term GANs, often carry maturities running a decade or longer. Each year’s federal apportionment covers that year’s debt service.2Federal Highway Administration. Grant Anticipation Revenue Vehicle (GARVEE) Bonds
Federal reimbursement of GARVEE debt service is capped at the federal share that would apply to the underlying project, which is typically 80 percent for federal-aid highway work and varies by program. The state remains responsible for the matching share, the same way it would with a pay-as-you-go project.1Office of the Law Revision Counsel. 23 U.S. Code 122 – Payments to States for Bond and Other Debt Instrument Financing
Who Issues Grant Anticipation Notes and for What
State departments of transportation are the most frequent issuers, given how heavily highway and transit projects lean on federal formula grants. But the instrument is not limited to roads. Counties, municipalities, transit authorities, port authorities, and other special-purpose entities also issue GANs whenever they hold a formal grant commitment that has not yet been disbursed.
Common project types include:
- Highway and bridge construction funded through federal-aid apportionments, the classic GARVEE case.
- Transit expansion, including light rail and bus rapid transit projects funded through Federal Transit Administration grants.
- Community development projects funded through Community Development Block Grants and similar HUD programs.
- Water, sewer, and environmental remediation work where federal or state grants cover a large share of cost.
The common thread is a big gap between when money must be spent and when grant reimbursements arrive. The larger and more capital-intensive the project, the more useful the anticipation note becomes.
Tax Treatment for Investors
Interest on GANs is generally excluded from federal income tax under IRC Section 103, which provides that gross income does not include interest on state or local bonds.3Office of the Law Revision Counsel. 26 USC 103 – Interest on State and Local Bonds That exemption is the same one that drives the broader municipal bond market and is the main reason individual investors buy municipal notes rather than taxable alternatives.
Three conditions can knock out the exemption. Interest becomes taxable if the bond is a private activity bond that fails the qualified-bond rules, if it is an arbitrage bond under Section 148, or if it fails the registration requirements of Section 149.3Office of the Law Revision Counsel. 26 USC 103 – Interest on State and Local Bonds For straightforward GANs issued by public entities for public projects, those traps generally do not apply, but bond counsel structures the deal to stay inside the safe harbor.
Many states also exempt interest on their own bonds from state and local tax, which is what produces the “triple tax-exempt” appeal for in-state buyers.
Arbitrage and Rebate
When an issuer sells tax-exempt notes but does not spend the proceeds right away, it invests them in the meantime. If those investment earnings exceed the yield on the notes, the issuer has earned arbitrage. Section 148 defines a bond as an arbitrage bond if proceeds are reasonably expected to be used to acquire higher-yielding investments, and issuers must generally rebate the excess earnings to the federal government to keep the tax exemption.4Office of the Law Revision Counsel. 26 USC 148 – Arbitrage Failing to make the required rebate can retroactively make interest taxable to investors. An initial temporary period allows unrestricted investment before yield restrictions kick in, giving issuers a practical window to deploy the proceeds.5Internal Revenue Service.

Risks to Understand Before Buying or Issuing
GANs are considered low-risk within the municipal market, but low risk is not no risk. The specific dangers depend heavily on the grant behind the notes.
Grant Delay
The most common risk is that the grant arrives later than expected. Federal appropriations are unpredictable, and when Congress operates under a continuing resolution rather than a full budget, obligation authority for highway programs may be released in installments.6Federal Highway Administration. Grant Anticipation Revenue Vehicles (GARVEEs) – FAQs The money is not gone, but a delay can force the issuer to extend the note or draw on backup liquidity, both of which add cost.
No Federal Guarantee
A point many investors miss: the federal government does not guarantee GARVEEs or any other form of grant anticipation debt.6Federal Highway Administration. Grant Anticipation Revenue Vehicles (GARVEEs) – FAQs The notes are backed only by the pledge of the issuing state or local government. If federal funding for the underlying program were cut through legislation, note holders would have no claim on the U.S. Treasury and would fall back on whatever secondary pledges and reserves the bond documents provide.
Formula Grants Versus Discretionary Grants
The type of grant matters enormously. Formula grants, like federal-aid highway apportionments, are distributed automatically based on statutory formulas tied to lane miles, population, fuel consumption, and similar factors. They are relatively predictable because changing the formula requires an act of Congress. Discretionary grants are awarded competitively and depend on annual appropriations decisions. Notes backed by discretionary grants carry meaningfully higher risk because the funding stream is less certain to continue at the expected level.
Rating agencies weigh this distinction heavily. GARVEEs backed by first-lien pledges on federal-aid highway formula funds have historically received investment-grade ratings, reflecting the long track record of the federal highway program. Notes tied to smaller or more politically vulnerable programs face tougher scrutiny.
Legislative and Programmatic Risk
The most remote but most severe risk is a wholesale change to the federal program that funds the grant. A dramatic restructuring of federal-aid highway funding, or a shift in the funding mechanism itself, could put pressure on outstanding GARVEEs. The risk is theoretical for well-established programs, but it matters more for longer-maturity instruments where political conditions can shift over the bond’s life.
How GANs Differ From Other Anticipation Notes
GANs sit in a family of short-term municipal instruments that share the same basic logic: borrow now against a known future revenue source. What differs is the source being anticipated.
- Tax Anticipation Notes (TANs) are repaid from expected tax collections, typically property or income taxes. The security is the issuer’s own tax base.
- Revenue Anticipation Notes (RANs) are repaid from expected non-tax revenues such as fees, charges, or state aid. Broader than TANs but still tied to the issuer’s own revenues.
- Bond Anticipation Notes (BANs) are repaid from the proceeds of a future long-term bond issue. They are placeholder borrowing until the permanent financing closes.
- Grant Anticipation Notes (GANs) are repaid from a specific grant commitment, usually from a higher level of government. The repayment source is external to the issuer.
That external dependency is both the strength and the weakness of a GAN. The revenue stream is insulated from local economic conditions, but it is exposed to decisions made by a different level of government entirely.
