Tax Anticipation Note (TAN)

Tax Anticipation Note (TAN)

A Tax Anticipation Note is a short-term debt instrument issued by a state or local government to bridge the gap between when it needs to spend money and when it expects to receive tax revenue. The government borrows now, spends the proceeds on capital projects or current operations, and repays the note once the anticipated taxes come in. Most Tax Anticipation Notes mature in one year or less, often timed to coincide with the annual tax collection deadline. Interest income from Tax Anticipation Notes is typically exempt from federal income tax, which keeps borrowing costs low for the issuer.

Think of a Tax Anticipation Note like a municipal payday loan: the government borrows against incoming tax checks it knows are coming.

Why Governments Issue Tax Anticipation Notes

Government revenues are cyclical. Property taxes might come in twice per year. Sales taxes arrive monthly. Income taxes peak at filing deadlines. But operating expenses and capital project needs do not wait for tax collection dates. A city that needs to begin bridge construction in June but will not collect property taxes until December faces a six-month cash flow gap. A Tax Anticipation Note fills that gap at a lower cost than other forms of short-term borrowing.

Tax Anticipation Notes are also faster to issue than long-term general obligation bonds, making them useful for urgent capital needs or unexpected shortfalls. In most jurisdictions, they can be authorized by the legislative body without a voter referendum.

How Tax Anticipation Notes Work as Investments

Investors buy Tax Anticipation Notes at a discount to face value, similar to Treasury bills. On the maturity date, the government repays the full face value. The investor's return is the difference between the discounted purchase price and the face value received at maturity. Because the notes are backed by specific anticipated tax receipts that have priority over other claims once collected, they are considered low-risk. That low risk, combined with federal tax exemption on the interest, makes them particularly attractive to investors in high tax brackets.

Tax Anticipation Notes vs. Other Anticipation Notes

Tax Anticipation Notes are one of several short-term municipal debt instruments, each backed by a different expected cash inflow.

  • Revenue Anticipation Notes (RANs): Backed by future revenues from municipal projects or facilities rather than tax collections.
  • Bond Anticipation Notes (BANs): Issued in advance of a planned long-term bond offering; repaid with the proceeds when the bonds are sold.
  • Tax and Revenue Anticipation Notes (TRANs): Combine Tax Anticipation Note and Revenue Anticipation Note features, backed by a mix of both tax and non-tax revenue.
  • Grant Anticipation Notes (GANs): Backed by expected federal grant funds.

Risks of Tax Anticipation Notes

The core risk for investors is that anticipated tax revenues do not materialize as projected. Economic downturns, delinquent taxpayers, or unexpected drops in assessed property values can all reduce collections below what the government forecast when it issued the note. California municipalities experienced exactly this risk during the 1990s when some communities could not repay Tax Anticipation Notes after expected revenues failed to arrive. Rating agencies evaluate each issuer's revenue base and tax collection history when assigning credit ratings to these instruments.
