What is Form 1099-INT?

The IRS form that reports every dollar of interest income paid to you

Form 1099-INT (Interest Income) is an information return issued by banks, brokerages, the U.S. Treasury, and bond issuers whenever they pay you $10 or more in interest during the year. The payer sends a copy to you and files the same data with the IRS, which uses it to cross-check your return.

Interest income is taxed as ordinary income — at the same rate as wages and salary, with no preferential capital gains rate. In the current elevated rate environment, savers earning 4%–5% on high-yield accounts, money market funds, and Treasury bills are seeing significantly higher interest income than in prior years — and more taxpayers are crossing the $1,500 Schedule B threshold for the first time.

Treasury Interest Is State-Tax-Free: Interest on T-bills, T-notes, T-bonds, I-Bonds, and EE Bonds (Box 3) is fully taxable federally but exempt from all state and local income taxes under federal law. If you earned Treasury interest in 2025, subtract it from your state return's taxable income — this is one of the most commonly missed deductions for savers who shifted to Treasuries.

Who Receives Form 1099-INT?

Virtually anyone with an interest-bearing account or savings bond

You Receive a 1099-INT For:

  • Savings & checking account interest — banks and credit unions
  • High-yield savings accounts (HYSA) — Ally, Marcus, SoFi, etc.
  • Certificates of deposit (CDs) — including early withdrawal penalties
  • Money market accounts — bank money market (not money market funds)
  • Treasury bills, notes, bonds, TIPS — via TreasuryDirect.gov
  • I-Bonds and EE Bonds — in the year you redeem them
  • Corporate bonds — brokerage accounts
  • Municipal bonds — Box 8 (tax-exempt federally)

No 1099-INT For:

  • IRA / 401(k) interest — reported on 1099-R only at withdrawal
  • Roth IRA earnings — tax-free, no current-year reporting
  • HSA earnings — tax-deferred, no current-year reporting
  • Money market fund dividends — reported on 1099-DIV instead
  • Interest under $10 — not required (but still technically taxable)
  • 529 plan earnings — tax-deferred until non-qualified withdrawal

Form 1099-INT Box-by-Box Guide

What every field means and where it goes on your tax return

Box 1
Interest Income — Taxable Total ordinary taxable interest: savings accounts, CDs, money market accounts, corporate bonds. Report on Schedule B Part I → Form 1040 Line 2b. This is the most commonly reported box — most filers will have an amount here.
Box 2
Early Withdrawal Penalty Penalty charged for cashing a CD before maturity. Even though it reduces your net interest, Box 1 shows the gross amount. Deduct Box 2 on Schedule 1, Line 18 — this is an above-the-line deduction.
Box 3
U.S. Savings Bonds & Treasury Interest Interest on T-bills, T-notes, T-bonds, TIPS, I-Bonds, and EE Bonds. Federally taxable → Schedule B. State and local tax-exempt → subtract from your state return. Download from TreasuryDirect.gov — this form is not mailed.
Box 4
Federal Income Tax Withheld (Backup Withholding) 24% withheld if you provided an incorrect or missing TIN. Claim as a tax payment credit on Form 1040 Line 25c — it reduces taxes owed. Submit Form W-9 to your institution to stop future withholding.
Box 5
Investment Expenses Obsolete since TCJA 2017 eliminated miscellaneous itemized deductions through 2025. Generally blank. No deduction available on 2025 federal returns.
Box 6
Foreign Tax Paid Withholding tax paid to a foreign government on foreign bond interest. Claim as Foreign Tax Credit (Form 1116 or Schedule 3 Line 1) — generally more valuable than a deduction. For ≤$300 single / ≤$600 MFJ, claim directly without Form 1116.
Box 7
Foreign Country The foreign country that imposed the tax shown in Box 6. Used when filing Form 1116 for the Foreign Tax Credit.
Box 8
Tax-Exempt Interest (Municipal Bonds) Federally tax-exempt interest from municipal bonds (state/city/county bond issuers). Report on Form 1040 Line 2a — NOT Line 2b. Do not include in Schedule B Part I. May be subject to state tax depending on whether your state exempts its own or all munis.
Box 9
Private Activity Bond Interest (AMT) Subset of Box 8 from bonds subject to Alternative Minimum Tax. If you owe AMT, include Box 9 on Form 6251. Typically relevant only for higher-income taxpayers with significant municipal bond holdings.
Box 10
Market Discount Accrued discount on bonds purchased below par value. May be treated as ordinary income rather than capital gain. Complex — consult IRS Publication 550 or a tax advisor if this box has an amount.
Box 11
Bond Premium (Taxable Bonds) Amortized premium on taxable bonds purchased above face value. Reduces Box 1 taxable interest — report on Schedule B with notation. You must elect to amortize; if not elected, add the premium to cost basis instead.
Box 12
Bond Premium on Treasury Obligations Same as Box 11 but for Treasury securities. Reduces Box 3 income on Schedule B.
Box 13
Bond Premium on Tax-Exempt Bonds Amortized premium on municipal bonds. Reduces Box 8 (already tax-free). Primarily a cost basis adjustment. No current-year tax impact for most filers.
Box 14
CUSIP Number Identifier for the tax-exempt or tax credit bond. Informational — used to identify specific bond instruments. No action required for most filers.
15–17
State Tax Information State payer ID (Box 15), state tax withheld (Box 16), state income amount (Box 17). Report on your state return as required.

When Do You Need Schedule B?

The $1,500 rule and other triggers for the additional schedule

File Schedule B If:
  • Total taxable interest (Box 1 + Box 3 from all 1099-INTs) exceeds $1,500
  • You had a financial interest in or signature authority over a foreign bank account
  • You received a distribution from a foreign trust
  • You received interest as a nominee (received interest belonging to someone else)
Skip Schedule B If:
  • Total interest is $1,500 or less from all sources
  • All interest is from domestic accounts only
  • No foreign accounts, trusts, or nominee situations apply
In this case, enter total interest directly on Form 1040, Line 2b.
Elevated rates mean more taxpayers need Schedule B in 2026. At 4.5% APY, a $35,000 balance generates ~$1,575 in interest — already over the $1,500 threshold. Combined with even modest interest from a second account, many savers who never filed Schedule B before will need it for their 2025 return.

How to Report Interest Income on Your Return

Step-by-step from 1099-INT to Form 1040

1
Gather All 1099-INT Forms Collect every 1099-INT from all banks, brokerages, and credit unions — they must arrive by January 31. For Treasury Direct (I-Bonds, T-bills), you must download your 1099-INT from TreasuryDirect.gov — it is not mailed. This is the most frequently missed source of interest income.
2
Total Your Taxable Interest Add all Box 1 amounts + all Box 3 amounts across every 1099-INT you received. This is your total taxable interest income. If the total exceeds $1,500, you'll need to complete Schedule B Part I before entering the total on Form 1040, Line 2b.
3
Report Tax-Exempt Interest Separately Box 8 (municipal bond interest) goes on Form 1040, Line 2a — not Line 2b. It is informational and does not increase your federal taxable income. Check whether your state taxes out-of-state municipal bond interest.
4
Subtract Treasury Interest on Your State Return Box 3 (Treasury/I-Bond interest) is federally taxable but state and local tax-exempt. Find your state return's "U.S. obligation interest" deduction line and subtract your total Box 3 amount. This is one of the most commonly missed state-tax deductions for savers who moved into Treasuries.
5
Handle Special Boxes Deduct Box 2 (early withdrawal penalty) on Schedule 1, Line 18. Claim Box 4 (backup withholding) as a tax payment on Form 1040 Line 25c. Claim Box 6 (foreign tax) on Form 1116 or Schedule 3 Line 1.

Common Mistakes to Avoid

Errors that most commonly lead to IRS notices and overpaid taxes

Forgetting to download Treasury Direct 1099-INT TreasuryDirect does not mail 1099-INT forms. Log into TreasuryDirect.gov each January, go to Manage Direct → 1099 Tax Forms, and download. Failing to do this is the single most common source of unreported interest income.
Reporting Box 8 (tax-exempt) as taxable income Municipal bond interest in Box 8 is federally tax-exempt. It goes on Form 1040 Line 2a — not Line 2b. Putting it on Line 2b means paying federal income tax on money that's legally tax-free.
Paying state tax on Treasury interest Box 3 (I-Bonds, T-bills, T-notes, T-bonds) is exempt from state and local income taxes. Most states have a specific deduction line for "U.S. obligation income." Forgetting this deduction means overpaying state taxes on every dollar of Treasury interest.
Missing the Schedule B filing requirement If your total taxable interest from all sources exceeds $1,500, you must file Schedule B. In the current high-rate environment, many savers crossing this threshold for the first time may not know Schedule B is required. The IRS will flag returns where income appears to be above $1,500 but Schedule B is missing.
Not deducting the CD early withdrawal penalty Box 2 is a deductible above-the-line penalty that reduces your AGI. It belongs on Schedule 1, Line 18 — not as a reduction to Box 1 income on Schedule B. Many taxpayers simply subtract it mentally but never actually claim the deduction on the return.
Missing I-Bond interest at redemption All interest accrued on an I-Bond since purchase is taxable in the year you redeem it — not spread across the years it accrued. A $10,000 I-Bond redeemed after 3 years at 6% average may generate $1,800+ in interest appearing on a single 1099-INT, creating a larger-than-expected tax bill.

Frequently Asked Questions

Common questions about Form 1099-INT and interest income taxation

Is interest from a high-yield savings account taxed differently?

No. Interest from any savings account — whether a 0.01% traditional account or a 5% HYSA — is taxed identically as ordinary income at your marginal federal income tax rate. There is no preferential rate for interest income the way there is for qualified dividends or long-term capital gains.

Is Treasury bill interest exempt from state taxes?

Yes. Interest on U.S. Treasury obligations — T-bills, T-notes, T-bonds, I-Bonds, EE Bonds, and TIPS — is exempt from state and local income taxes under federal law. This interest appears in Box 3 of your 1099-INT. On your state return, subtract Box 3 from your taxable income. It remains fully subject to federal income tax.

How do I get my 1099-INT from TreasuryDirect for I-Bonds?

TreasuryDirect does not mail 1099-INT forms. You must download them yourself: log into your account at TreasuryDirect.gov, navigate to "Manage Direct," then select "1099 Tax Forms," and choose the applicable tax year. Download and save the PDF. If you redeemed I-Bonds in 2025, your 1099-INT will reflect all accumulated interest since the date of purchase.

Do I owe taxes on interest under $10 if I didn't receive a 1099-INT?

Technically yes — all interest income is taxable regardless of amount. The $10 threshold determines when a payer is required to issue a 1099-INT, not when income is taxable. In practice, the IRS rarely pursues very small unreported amounts, but the legal obligation exists. If you earn interest on multiple accounts each just under $10, the combined total should still be reported.

Is municipal bond interest ever taxable?

Municipal bond interest is federally tax-exempt but may be taxable at the state level. Most states exempt interest from their own state's bonds but tax interest from other states' bonds. A few states (like California and New York) are notable for taxing out-of-state muni interest. Additionally, interest from private activity bonds (Box 9) may be subject to the Alternative Minimum Tax.

Does interest income affect my Social Security benefits?

Yes. Interest income (including tax-exempt interest from Box 8) is counted in the "combined income" formula that determines how much of your Social Security benefits are taxable. For single filers, combined income over $25,000 causes up to 50% of benefits to become taxable; over $34,000 causes up to 85% to be taxable. Retirees with significant interest income may push more of their Social Security into the taxable range.

What is backup withholding and how do I stop it?

Backup withholding is a 24% tax withheld from interest payments when you haven't provided a valid TIN (Social Security Number) to the payer, or when the IRS has notified the payer that your TIN is incorrect. The withheld amount appears in Box 4 and is credited against your tax liability on Form 1040 Line 25c. To stop backup withholding, submit Form W-9 with your correct TIN to the financial institution.

About IRS Form 1099-INT (2026)

Form 1099-INT (Interest Income) is issued by banks, credit unions, brokerages, and the U.S. Treasury whenever they pay $10 or more in interest during the year. With interest rates remaining elevated through 2025, more taxpayers than in prior years are receiving significant 1099-INT amounts — particularly from high-yield savings accounts, money market accounts, Treasury bills, and I-Bond redemptions. Interest income is taxed as ordinary income at marginal rates, with no preferential capital gains treatment.

Key distinctions: Box 1 (taxable interest) and Box 3 (Treasury/I-Bond interest) go on Schedule B and Form 1040 Line 2b. Box 8 (municipal bond interest) is federally tax-exempt and goes on Line 2a only. Treasury interest (Box 3) is additionally exempt from all state and local taxes. Schedule B is required when combined taxable interest exceeds $1,500.
