An amortizable bond premium occurs when you pay more than a bond’s face value, and the extra amount can be spread out over the life of the bond. Amortizing bond premium is generally optional but affects how bond interest income is reported.
📈 Why It Happens
Investors pay a premium when a bond offers a higher interest rate than current market rates. The premium reflects the bond’s added value—but for tax purposes, it can be gradually deducted.
🧾 Tax Treatment
- Taxable Bonds (e.g., corporate or U.S. Treasury bonds):
- You can elect to amortize the premium.
- The amortized amount reduces taxable interest income each year.
- You cannot deduct the premium as a lump sum.
- Tax-Exempt Bonds (e.g., municipal bonds):
- You must amortize the premium.
- The amortized amount does not reduce taxable income, but it lowers the bond’s cost basis, affecting gain/loss when sold.
🛠️ Example:
You buy a bond for $1,100 with a face value of $1,000, and it matures in 10 years.
- The $100 premium is amortized over 10 years.
- Each year, you reduce your taxable interest income by $10 (for taxable bonds).
📄 How to Report
- Use Form 1099-INT or Form 1099-OID to report interest income.
- Keep track of amortization using Form 8949 or your own records.
- You may need to make an election under IRC Section 171 to amortize the premium.
