Quick Answer
Report interest income on Form 1040 Line 2b if you earned more than $1,500, or directly on Line 2a if under $1,500. You'll receive Form 1099-INT for accounts earning $10+ in interest. All interest income is taxed as ordinary income at your regular tax rate.

Where to report interest income on your tax return
According to [IRS Publication 17](https://www.irs.gov/pub/irs-pdf/p17.pdf), all interest income must be reported on your Form 1040, but where you report it depends on how much you earned:
$1,500 or less: Report the total directly on Form 1040, Line 2a (Taxable Interest)
Over $1,500: Complete Schedule B and enter the total on Form 1040, Line 2b
Understanding Form 1099-INT
You'll receive Form 1099-INT from any institution that paid you $10 or more in interest during the tax year. This form shows:
Example: Reporting $2,400 in interest income
Let's say you earned interest from multiple sources:
Since this exceeds $1,500, you must:
1. List each source on Schedule B
2. Enter the $2,400 total on Form 1040, Line 2b
3. Pay taxes at your ordinary income rate
If you're in the 22% tax bracket, you'll owe $528 in federal taxes on this interest income.
Types of interest income and tax treatment
Key factors that affect interest income reporting
Special situations to watch for
Accrued interest on bond purchases: If you buy a bond between interest payment dates, part of your purchase price is accrued interest that's immediately deductible.
Original Issue Discount (OID): Zero-coupon bonds and discounted bonds may require annual income recognition even if no cash is received.
Penalty for early withdrawal: If you paid penalties for early CD withdrawal, this reduces your taxable interest income.
What you should do
1. Gather all 1099-INT forms by January 31st
2. Keep records of any interest under $10 that didn't generate a 1099-INT
3. Check for missed interest from forgotten accounts or small amounts
4. Consider timing for interest-bearing investments near year-end
Use our [return scanner](return-scanner) to verify you've reported all required interest income and haven't missed any sources.
Key takeaway: All interest income is taxable at ordinary rates. Report amounts over $1,500 on Schedule B, and remember that you owe taxes on roughly 22-37% of your interest income depending on your tax bracket.

Key Takeaway: All interest income is taxable at ordinary rates - expect to pay 22-37% of your interest earnings in federal taxes depending on your income level.

New investors in their 20s-30s just starting to earn meaningful interest income
Interest income for young investors
As a young investor, you're probably earning interest from high-yield savings accounts, CDs, or maybe your first bond investments. The good news: if you're earning under $1,500 in total interest, reporting is simple - just enter the amount on Line 2a of Form 1040.
Common mistakes young investors make
Forgetting small amounts: That $15 from your old savings account still counts, even without a 1099-INT
Missing online accounts: Digital banks and fintech apps sometimes send 1099-INT forms later
Ignoring savings bond interest: Series I bonds you bought during inflation can generate substantial taxable interest
Building an interest income strategy
Unlike dividends that can qualify for lower tax rates, ALL interest is taxed as ordinary income. This means if you're in the 22% bracket, every $100 in interest costs you $22 in taxes.
Consider focusing interest-bearing investments in tax-advantaged accounts (401k, IRA) where the income grows tax-deferred.
Key takeaway: Young investors should prioritize tax-advantaged accounts for interest-bearing investments since all interest is taxed at ordinary income rates.

Investors in their 40s-60s with substantial interest income from CDs, bonds, and savings
Managing substantial interest income
As your investment portfolio grows, interest income becomes more significant and complex. You're likely dealing with:
Tax-efficient interest income strategies
Municipal bonds: Interest is usually federally tax-exempt, valuable if you're in higher brackets
Treasury securities: Federal taxable but state tax-exempt in most states
Tax-loss harvesting: Offset interest income with capital losses where possible
Account location: Hold high-interest investments in tax-deferred accounts when possible
Planning for retirement transition
Many pre-retirees increase their allocation to interest-bearing investments for safety, but this creates higher tax bills. Consider:
If you're earning $5,000+ in annual interest income and you're in the 32% bracket, you're paying $1,600+ annually in taxes that could potentially be deferred or eliminated with better account placement.
Key takeaway: High earners should consider municipal bonds and tax-advantaged account placement for interest-bearing investments to reduce annual tax liability.
