Yes, you owe federal income tax on savings account interest, and most states tax it too

Any interest your savings account earns counts as taxable income. The bank reports it to the IRS on a Form 1099-INT if the interest is $10 or more in a calendar year. You report this interest on your tax return, and it gets taxed at your ordinary income tax rate — the same rate as your salary or wages.

The amount matters less than you might think. Even $5 in interest is technically taxable, though the bank won't send you a form for it. You still owe tax on it if you file a return. Most people with savings accounts earn small enough amounts that the tax bite is minimal, but the obligation is real.

State income tax works the same way in most states. If your state has an income tax, it taxes savings interest just like the federal government does. A few states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — have no state income tax at all, so you'd only owe federal tax.

Key Takeaways

  • Banks report savings interest of $10 or more on Form 1099-INT, which goes to the IRS and your state tax authority.
  • You report this interest on your tax return as ordinary income, taxed at your full income tax rate, not a special rate.
  • Interest under $10 is still taxable but won't appear on a 1099-INT, so you have to track it yourself if the bank doesn't report it.
  • Eight states have no income tax, so residents owe only federal tax on savings interest; all other states tax it as well.
  • High-yield savings accounts earn more interest, which means a larger tax bill — but the after-tax return is usually still better than traditional savings.

How the IRS knows about your savings interest

Banks are required to send both you and the IRS a Form 1099-INT for any account that earns $10 or more in interest during the calendar year. You receive Copy B in the mail by January 31 of the following year. The bank sends Copy A to the IRS at the same time.

The IRS matches the 1099-INT it receives from the bank against your tax return. If you don't report the interest, the IRS will notice the mismatch. This is one of the easiest discrepancies for the IRS to catch because the bank's report is automatic and electronic.

Interest under $10 won't trigger a 1099-INT, but you're still legally required to report it if you file a return. Many people don't know this and assume that if there's no form, there's no tax. That's not how it works. Keep your own records of small interest amounts so you can report them accurately.

What counts as savings account interest

Interest is money the bank pays you for letting them hold your money. It shows up as a separate line item on your account statements, distinct from deposits you make yourself. Regular savings accounts, money market accounts, and certificates of deposit (CDs) all generate interest that's taxable.

High-yield savings accounts earn significantly more interest than traditional savings accounts — sometimes 4% to 5% annually compared to 0.01% or less at big banks. The higher rate means a bigger tax bill, but the after-tax return is usually still higher than you'd get elsewhere. If you have $10,000 in a high-yield account earning 4.5%, you'd owe tax on roughly $450 in interest for the year.

Bonus interest that banks sometimes offer to new customers counts the same way. If a bank gives you $200 for opening an account, that $200 is taxable income and should appear on a 1099-INT.

How much tax you'll actually owe

Your tax rate on savings interest depends on your total income and filing status. Interest is added to your other income and taxed at your marginal rate — the rate that applies to your highest dollars of income. If you're in the 22% federal tax bracket, every dollar of interest is taxed at 22%. If you're in the 12% bracket, it's 12%.

State tax varies by state. New York taxes interest at rates up to 6.85%. California goes up to 13.3%. Some states have flat rates — Colorado is 4.4%, for example. A few states exempt interest income entirely, though this is rare. Check your state's tax authority website to find your state's rate.

The combined federal and state rate is what you actually owe. Someone in the 22% federal bracket living in California would owe roughly 35% of their interest in tax. That same person in Texas (no state income tax) would owe 22%. The difference adds up quickly on larger balances.

Reporting interest on your tax return

If you received a 1099-INT, you report the interest on Schedule B (Interest and Ordinary Dividends), which attaches to your Form 1040. You list each account's interest separately if you have multiple accounts, though many people just add them together and report the total.

The interest amount from Schedule B flows to your Form 1040 as part of your total income. It's not a separate line item on the main form — it gets combined with wages, self-employment income, and other sources to calculate your total taxable income.

If you use tax software, it usually walks you through entering the 1099-INT information. If you file by hand or with a tax professional, bring the 1099-INT with you. The form shows the account number and the exact interest amount, so there's little room for error if you enter it correctly.

When you might not owe tax on savings interest

You don't owe federal income tax if your total income is below the standard deduction for your filing status. For 2024, the standard deduction is $14,600 for single filers and $29,200 for married filing jointly. If your only income is $8,000 in savings interest and you're single, you wouldn't owe federal tax because you're below the threshold.

However, you might still be required to file a return for other reasons — to claim a refundable tax credit, for example. And if you have a 1099-INT, the IRS will expect to see it reported on your return, even if you don't owe tax. Filing shows the IRS that you received and reported the income.

Some people use savings accounts held in the name of a minor child to shift income to a lower tax bracket. The child's standard deduction still applies, so a small amount of interest income might not be taxed. But this strategy has limits, and the rules are complex. A tax professional can advise whether it makes sense for your situation.

Strategies to reduce the tax on savings interest

You can't avoid the tax, but you can reduce the amount of interest you earn and therefore the tax you owe. This sounds backwards, but it matters when comparing accounts. A high-yield savings account earning 4.5% might net you more after tax than a CD earning 5% if the CD has a penalty for early withdrawal that you'd have to pay.

Tax-advantaged accounts like IRAs and 401(k)s let interest grow without annual tax. Interest earned inside these accounts isn't reported on a 1099-INT and doesn't show up on your tax return. You only pay tax when you withdraw the money in retirement. If you have money to save beyond your emergency fund, maximizing contributions to these accounts first reduces your overall tax burden.

Some people use Treasury bonds or I Bonds instead of savings accounts. Interest on I Bonds is exempt from state and local tax, which can save money if you live in a high-tax state. The federal tax is still owed, but the state savings can be significant. These bonds have their own rules and restrictions, so research them before deciding.

Frequently Asked Questions

Do I have to report savings interest if I didn't get a 1099-INT?

Yes. If your interest was under $10, the bank won't send a form, but you still owe tax on it if you file a return. Keep your own records of interest earned and report the total on Schedule B. The IRS expects to see all interest income reported, not just amounts on 1099-INTs.

What if the 1099-INT has the wrong amount?

Contact the bank immediately and ask them to issue a corrected form. They'll send you a corrected 1099-INT and file a corrected version with the IRS. Don't report the wrong amount on your return — wait for the correction. If you've already filed, you can file an amended return once you have the correct form.

Can I deduct savings account fees from the interest I report?

No. You report the full interest amount on your tax return. Account fees are not deductible against interest income. However, if you have significant investment expenses, you might be able to deduct them as miscellaneous itemized deductions, but the rules are strict and the threshold is high.

Is interest from a joint savings account split between owners for tax purposes?

Not automatically. The bank reports the full interest amount on a single 1099-INT. You and the other owner need to decide how to split the income for tax purposes — usually 50/50 if you own it equally. Each person reports their share on their own tax return. Coordinate with the other owner so you don't both report the full amount.

Do I owe tax on interest if I'm retired and don't work?

Yes. Retirement status doesn't change the tax rules. Interest is taxable income regardless of whether you're working. However, if your total income (including interest) is below the standard deduction, you won't owe federal tax. Many retirees fall into this category, but you should still file to report the interest and potentially claim credits you're may have access to to.
