Yes, savings accounts are taxable, but only the interest the bank pays you, not the money you deposited. That interest counts as ordinary income in the year the bank credits it to your account, gets added to your wages and other earnings, and is taxed at your regular federal rate, which runs from 10% to 37% for 2026.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Most savers owe modest amounts, but reporting the interest correctly avoids IRS notices and penalties.
Principal Isn’t Taxed Again, Interest Is
The money you originally deposited is money you already earned and, in most cases, already paid tax on. Moving it into a savings account doesn’t create a new tax event. What the federal government taxes is the new money the bank pays you for keeping funds there.
That interest is gross income under Internal Revenue Code Section 61.2Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined The implementing regulation says it plainly: interest on savings or other bank deposits is fully taxable.3eCFR. 26 CFR 1.61-7 – Interest The IRS does not tax your account balance each year. It taxes the growth.
When the Interest Counts as Income
Interest is taxable in the year the bank credits it, not the year you withdraw it. This is the constructive receipt rule: if the money is available to you, the IRS treats it as received.4eCFR. 26 CFR 1.451-2 – Constructive Receipt of Income For accounts that post interest monthly, every monthly credit becomes income for that calendar year.
You cannot delay the tax by leaving the money in the account. Once the interest hits your balance, it’s reportable for that year.
How Much You’ll Pay
Savings interest is taxed at ordinary income rates, not the lower rates that apply to long-term capital gains. It stacks on top of your wages and other income, and the total determines your marginal bracket. For 2026:1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
- 10%: up to $12,400 (single) or $24,800 (married filing jointly)
- 12%: $12,401–$50,400 (single) or $24,801–$100,800 (joint)
- 22%: $50,401–$105,700 (single) or $100,801–$211,400 (joint)
- 24%: $105,701–$201,775 (single) or $211,401–$403,550 (joint)
- 32%: $201,776–$256,225 (single) or $403,551–$512,450 (joint)
- 35%: $256,226–$640,600 (single) or $512,451–$768,700 (joint)
- 37%: above $640,600 (single) or above $768,700 (joint)
Most savers see their interest taxed at 10% or 12%. The interest itself rarely pushes anyone into a higher bracket; the rate you pay is essentially the one your other income already put you in.
Higher earners owe an extra 3.8% net investment income tax on top of the regular rate once modified adjusted gross income exceeds $200,000 (single), $250,000 (joint), or $125,000 (married filing separately). Savings interest counts as net investment income for this surcharge.5Internal Revenue Service. Topic No. 559, Net Investment Income Tax Someone in the 35% bracket who also owes the NIIT could effectively pay 38.8% on interest.
Most states also tax interest, using the same income definition the federal government uses. State rates run from zero in states with no income tax to over 13% at the top.
The 1099-INT and the $10 Threshold
Banks must send you and the IRS a Form 1099-INT when your account earns $10 or more in interest during the year.6Internal Revenue Service. About Form 1099-INT, Interest Income The form is due to you by January 31.7Internal Revenue Service. General Instructions for Certain Information Returns (2025)
Earning less than $10 does not make the interest tax-free. You still have to report all interest income, even amounts under a dollar.8Internal Revenue Service. Topic No. 403, Interest Received The $10 threshold only controls whether the bank sends paperwork. If you don’t get a 1099-INT, add up the amounts on your monthly statements yourself.
Putting It on Your Return
Interest income goes on line 2b of Form 1040. For most people with one or two bank accounts, that’s the whole job: copy Box 1 of your 1099-INT onto the return.
If your total taxable interest across all sources tops $1,500, you also have to complete Schedule B (Form 1040), listing each bank or institution and the amount it paid.9Internal Revenue Service. 2025 Schedule B (Form 1040) – Interest and Ordinary Dividends With high-yield savings accounts paying 4% or more recently, this is easier to hit than it used to be. A balance of roughly $38,000 at 4% clears the threshold.
Tax software handles the mechanics automatically once you enter the 1099-INT.
Nominee Interest
If a 1099-INT arrives in your name but part of the interest belongs to someone else (a joint account with a non-spouse, for example), report the full amount on Schedule B and subtract the other person’s share as a nominee distribution. You then issue a 1099-INT to the actual owner for their share.10Internal Revenue Service. Instructions for Schedule B
Backup Withholding and the W-9
When you open an account, the bank has you complete a Form W-9 certifying your taxpayer identification number. If you skip it, provide the wrong number, or the IRS notifies the bank of a mismatch, the bank must withhold 24% of your interest and send it to the IRS.11Internal Revenue Service. Publication 15 (2026), (Circular E), Employer’s Tax Guide
Backup withholding appears in Box 4 of your 1099-INT. It’s not an extra tax; it’s a prepayment credited against your return like wage withholding. But 24 cents of every interest dollar leaves your account immediately. A correct, signed W-9 on file with the bank prevents it.
Early Withdrawal Penalties Are Deductible
If you break a CD or time-deposit account before maturity, the bank’s penalty is deductible as an adjustment to income on Schedule 1 (Form 1040), line 18. It reduces your taxable income before you get to itemizing, and you can claim it even if the penalty exceeds the interest you earned that year.12Internal Revenue Service. Publication 550 (2024), Investment Income and Expenses
The penalty usually appears in Box 2 of the 1099-INT or Box 3 of Form 1099-OID. Report the interest as income first, then take the penalty deduction separately. Tax software doesn’t always prompt for it, so check.
Where These Rules Don’t Apply
Some savings vehicles follow different rules, and it’s worth knowing the edges so you don’t apply the wrong ones.
Interest earned inside a traditional IRA, Roth IRA, HSA, or 529 plan is not taxed in the year it’s credited. Traditional IRAs defer tax until you take distributions. Roth IRAs, HSAs used for qualified medical expenses, and 529 earnings used for qualified education expenses come out tax-free.13Internal Revenue Service. Publication 969 (2025), Health Savings Accounts and Other Tax-Favored Health Plans14Internal Revenue Service. 529 Plans: Questions and Answers The trade-off is contribution limits and withdrawal restrictions a regular savings account doesn’t have.
Series EE and Series I savings bonds let you defer reporting interest until you redeem them or they mature, up to 30 years, and the interest is exempt from state and local income tax.15TreasuryDirect. Tax Information for EE and I Bonds If the proceeds go toward qualified higher education expenses, Form 8815 may exclude the interest from federal tax entirely, subject to income phase-outs.
Opening a savings account in a child’s name doesn’t shelter the interest. If a child’s unearned income tops $2,700 in 2026, the excess can be taxed at the parent’s marginal rate under the kiddie tax rules, which apply to children under 19 (or under 24 if they’re full-time students).16Internal Revenue Service. Topic No. 553, Tax on a Child’s Investment and Other Unearned Income (Kiddie Tax)
Interest in a foreign savings account is still taxable on your federal return, and the account itself may trigger separate reporting. If your combined foreign account balances exceed $10,000 at any point in the year, you must file an FBAR with FinCEN regardless of how much interest you earned. Penalties for non-willful failures start at $10,000 per violation.17Internal Revenue Service. Report of Foreign Bank and Financial Accounts (FBAR) A separate FATCA filing on Form 8938 may also apply at higher thresholds.18Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets
When You Need to Pay Quarterly
If interest income will push what you owe at filing time to $1,000 or more, the IRS expects quarterly estimated payments through the year rather than a single April settlement.19Internal Revenue Service. Estimated Taxes Most W-2 employees with moderate savings are covered by paycheck withholding. Retirees, self-employed workers, and anyone with a large high-yield balance should run the numbers.
To avoid the underpayment penalty, pay at least 90% of your current-year tax or 100% of last year’s tax, whichever is smaller. Bumping up your W-4 withholding at work is often simpler than filing quarterly vouchers.
What Happens If You Don’t Report It
The IRS gets a copy of every 1099-INT the bank sends you, and its matching program flags unreported interest automatically. The usual result is a CP2000 notice proposing additional tax. If you simply forgot, paying the corrected amount plus interest on the underpayment resolves it. If you owe and pay late, the failure-to-pay penalty runs 0.5% per month on the unpaid balance, capped at 25%.20Internal Revenue Service. Failure to Pay Penalty For most savings-account amounts the penalty is small, but it compounds with interest charges and is easily avoided by reporting the number in the first place.
