How Are Zero Coupon Bonds Taxed?

Zero coupon bonds are taxed differently because they don’t pay regular interest. Instead, they’re sold at a discount and reach full value at maturity. Each year, investors must report “imputed interest”—the difference between the purchase price and maturity value—even though they don’t receive cash until maturity. This amount gets taxed as ordinary income. Some, like municipal zero coupon bonds, may be exempt from federal or state taxes. But, most are fully taxable.

A financial advisor can help you with zero coupon bonds by addressing tax impacts, managing imputed interest, and aligning them with your goals.

What Are Zero Coupon Bonds?

Zero coupon bonds are a type of bond that differs from traditional bonds in that they don’t pay periodic interest, also known as “coupons,” over time. Instead, they are sold at a substantial discount to their face value and mature at full value.

For example, an investor might purchase a zero coupon bond for $700 that will pay $1,000 at maturity. The difference between the purchase price and the face value represents the bondholder’s return. These bonds are often issued by corporations, municipalities or the federal government, and they typically have longer maturities, ranging from 10 to 30 years.

The way zero coupon bonds work is straightforward: You buy the bond at a discounted price and wait for it to mature. There are no interest payments along the way, so your return is solely realized when the bond reaches maturity and you receive its full face value. This makes them an attractive option for investors who want a guaranteed return at a specific future date, such as for a child’s college education or retirement. However, because you won’t receive any payments until maturity, you need to be comfortable with the long-term nature of this investment.

How Zero Coupon Bonds Are Taxed

While zero coupon bonds can provide a predictable future payout, there is an important tax consideration. Despite not receiving cash payments, the IRS requires investors to pay taxes annually on the imputed interest, or the amount the bond is theoretically earning each year as it grows toward its face value. This phantom income can be a drawback, especially for investors in higher tax brackets.

Imputed interest represents the bond’s accrued value as it approaches maturity. This amount is treated as taxable income by the IRS and is taxed as ordinary income, not as capital gains. Investors must report this imputed interest annually, even though they won’t receive the bond’s full value until maturity.

For federal tax purposes, the interest earned on zero coupon bonds is taxed at the investor’s regular income tax rate. Additionally, state and local taxes may apply, depending on where you live and the type of bond. However, some zero coupon bonds, such as municipal bonds and select corporate zero coupon bonds with tax-exempt status, may offer tax advantages, as the interest earned on these bonds may be exempt from federal or state taxes.

Pros and Cons of Zero Coupon Bonds

Like other financial instruments, zero coupon bonds come with their own set of advantages and drawbacks. Here are three you should consider for each.

Pros of Zero Coupon Bonds

Certainty of future payout: One of the biggest advantages of zero coupon bonds is the certainty of their future payout. Because they don’t have fluctuating interest rates, you know exactly how much you will receive at maturity. This makes them a popular choice for goals like saving for retirement or funding a child’s education.
Lower cost of entry: Zero coupon bonds are typically sold at a deep discount to their face value, allowing investors to enter at a lower cost. This can make them attractive for those looking to invest a smaller amount of money upfront with the expectation of a larger return down the line.
No reinvestment risk: Additionally, since zero coupon bonds don’t pay interest periodically, investors don’t face reinvestment risk. In other words, you won’t need to worry about finding new investment opportunities for the interest payments you would otherwise receive from traditional bonds.

Cons of Zero Coupon Bonds

Tax treatment: Even though you don’t receive actual cash payments until maturity, the IRS requires you to pay taxes on the bond’s “imputed interest” each year. This phantom income can result in a tax bill without any cash in hand to cover it.
Long maturities: Another drawback is that zero coupon bonds tend to have long maturities, often spanning 10 to 30 years. This means your investment is tied up for a significant period, limiting liquidity if you need the funds earlier than expected.
Sensitivity to rate changes: Lastly, zero coupon bonds are sensitive to interest rate changes. If interest rates rise, the value of your bond on the secondary market could fall, leaving you with a potential loss if you need to sell before maturity.

Bottom Line

A man reviewing his investment portfolio.

Zero coupon bonds are taxed differently from traditional bonds due to their lack of periodic interest payments. Investors are required to report and pay taxes annually on imputed interest, even though they don’t receive cash until the bond matures. This phantom income can lead to unexpected tax liabilities, especially for those in higher tax brackets. It’s important to understand these tax implications before investing in zero coupon bonds, as they can significantly impact your overall return.
