There is no fixed amount of bank interest that is automatically tax-free under federal law. Every dollar of interest your savings account, checking account, or CD pays you counts as ordinary income.1Office of the Law Revision Counsel. 26 U.S.C. 61 – Gross Income Defined Whether you actually owe tax on it depends on your total income, your filing status, and whether the money is sitting in a tax-advantaged account. For most people the practical answer to “how much bank interest is tax free” is: as much as fits under your standard deduction once all your other income is counted, and nothing beyond that.
How Bank Interest Is Taxed
Interest from a bank deposit is treated the same way as wages. It stacks on top of your other income and is taxed at your marginal rate.2eCFR. 26 CFR 1.61-7 – Interest For 2026, federal ordinary income rates run from 10% to 37% depending on total taxable income and filing status.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
So if your job already puts you in the 22% bracket, the next dollar of savings interest is taxed at 22% too. There is no separate, lower rate for interest, and no built-in personal exemption for it.
When the Standard Deduction Covers Your Interest
The most common way people end up paying no tax on bank interest is by having little enough total income that the standard deduction absorbs everything. For the 2026 tax year, the standard deduction is:3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- $16,100 for single filers
- $32,200 for married couples filing jointly
- $24,150 for head of household
Taxpayers 65 or older get an additional deduction of roughly $1,600 to $2,000 on top of those figures, depending on filing status.4Office of the Law Revision Counsel. 26 U.S.C. 63 – Taxable Income Defined
If your wages, Social Security, interest, and everything else combined stay below your standard deduction, you owe no federal income tax. A retired single filer with $10,000 in Social Security and $3,000 in bank interest lands well under $16,100 and pays nothing. If your gross income falls below the deduction, you also usually do not need to file a return at all, though special rules apply if you have self-employment income or owe certain other taxes.5Internal Revenue Service. Check if You Need to File a Tax Return
For a working household, wages typically eat up the deduction long before interest gets counted. Once that happens, every dollar of interest is taxable. The standard deduction only makes interest effectively tax-free when your overall income is quite low.
The $10 Rule Is Not a Tax-Free Threshold
A widespread misconception says the first $10 of bank interest is tax-free. It is not. The $10 figure is only the point at which the bank has to send you and the IRS a Form 1099-INT.6Office of the Law Revision Counsel. 26 U.S.C. 6049 – Returns Regarding Payments of Interest It is a paperwork trigger for the bank, not an exemption for you. If you are otherwise required to file a return, you must report all your interest, right down to a few cents, whether or not you got a 1099.7eCFR. 26 CFR 1.6049-6 – Statements to Recipients of Interest Payments
Interest That Is Actually Tax-Free by Law
A few kinds of interest are legally excluded from federal income tax no matter how much you earn. None of them are ordinary bank deposit interest, but if you are looking for genuinely tax-free interest, these are the categories to know.
Municipal Bond Interest
Interest on bonds issued by state and local governments is generally excluded from federal income tax.8Office of the Law Revision Counsel. 26 U.S.C. 103 – Interest on State and Local Bonds The exclusion applies at any income level, which is why higher-income investors often hold “munis.” Certain private-activity and arbitrage bonds do not qualify. State income tax treatment varies: many states exempt interest on bonds issued in-state and tax interest on bonds from other states.
U.S. Savings Bond Interest Used for Education
If you cash in Series EE or Series I savings bonds and use the proceeds for qualified higher education expenses, the interest can be excluded from federal tax entirely.9Office of the Law Revision Counsel. 26 U.S.C. 135 – Income From United States Savings Bonds Used to Pay Higher Education Tuition and Fees The bonds must have been issued after 1989, the owner must have been at least 24 when the bonds were bought, and the expenses must be for you, your spouse, or a dependent.10TreasuryDirect. Using Bonds for Higher Education The exclusion phases out at higher incomes. For 2025, the phase-out began at $99,500 of modified adjusted gross income for single filers and $149,250 for joint filers, with the benefit gone entirely at $114,500 and $179,250.11Internal Revenue Service. Form 8815 – Exclusion of Interest From Series EE and I U.S. Savings Bonds Married filing separately is disqualified. Thresholds adjust with inflation.
Interest Inside Tax-Advantaged Accounts
If your savings sit inside certain accounts, the interest follows the account’s rules instead of showing up as taxable interest on your return:
- Health Savings Accounts. Earnings inside an HSA are tax-free while they stay in the account, and withdrawals for qualified medical expenses are also tax-free.12Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans
- Roth IRAs. Interest grows without current tax, and qualified distributions after age 59½ (and at least five years after your first contribution) come out tax-free.13Internal Revenue Service. Roth IRAs
- Traditional IRAs and 401(k)s. Interest is not taxed as it accrues, but withdrawals are taxed as ordinary income. The tax is deferred, not erased.
A CD held inside an IRA, for example, does not generate a taxable 1099-INT for you each year.
The Extra 3.8% Tax for Higher Earners
At the other end of the income scale, high earners pay an additional 3.8% net investment income tax on interest and other investment income. It kicks in once your modified adjusted gross income passes:14Office of the Law Revision Counsel. 26 U.S.C. 1411 – Imposition of Tax
- $200,000 for single or head of household
- $250,000 for married filing jointly
- $125,000 for married filing separately
The 3.8% applies to the lesser of your net investment income or the amount by which your MAGI exceeds the threshold.15Internal Revenue Service. Topic No. 559 – Net Investment Income Tax These thresholds are not indexed to inflation, so more taxpayers cross them each year. This surtax is on top of the regular income tax on the interest.
Reporting Your Interest
Collect every Form 1099-INT from your banks and credit unions by early February, and check your statements for small interest payments under $10 that never generated a 1099. Those amounts still belong on your return. If your total taxable interest is more than $1,500, you have to complete Schedule B (Form 1040) and list each payer.16Internal Revenue Service. About Schedule B (Form 1040) – Interest and Ordinary Dividends If it is $1,500 or less, you can put it straight on the 1040.
The IRS gets a copy of every 1099-INT your bank issues, so unreported interest is one of the easiest mismatches for its automated systems to spot. Leaving small amounts off the return can trigger a failure-to-pay penalty of 0.5% of the unpaid tax per month, up to 25%.17Internal Revenue Service.
