Interest on your savings account is taxable income

The interest your bank pays you on a savings account counts as ordinary income on your federal tax return. The IRS treats it the same way it treats wages or salary — you owe income tax on the full amount. Your bank will send you a Form 1099-INT each January listing all the interest you earned during the previous year, and you report that figure on your tax return.

How much tax you actually pay depends on your total income and your tax bracket. Someone in the 22% tax bracket pays roughly 22 cents in federal tax for every dollar of interest earned. Someone in the 12% bracket pays roughly 12 cents. State income tax, where your state has one, applies on top of that. The exact rate varies by state — some states do not tax interest income at all, while others tax it at rates up to 13%.

You owe this tax whether the interest is small or large. Even $5 in annual interest is technically taxable, though the IRS does not require banks to issue a 1099-INT unless interest reaches $10 or more in a calendar year. That does not mean you can ignore smaller amounts — you are still required to report them if you received them.

Key Takeaways

  • All interest earned in a savings account is taxable as ordinary income at your marginal tax rate, both federally and at the state level where applicable.
  • Your bank sends a Form 1099-INT in January for any interest of $10 or more earned during the previous year, and you report this on your tax return.
  • The tax you owe on interest depends on your total income and tax bracket, not on the size of the interest amount itself.
  • Some states do not tax interest income, while others tax it at rates between 1% and 13%, so your state of residence affects your total tax bill.
  • Interest earned in tax-advantaged accounts like Roth IRAs or 529 plans may not be taxable in the year earned, depending on the account type and withdrawal rules.

When the IRS requires your bank to report interest

Banks issue a Form 1099-INT when you earn $10 or more in interest during a calendar year. This form shows your name, Social Security number, the bank's name, and the total interest paid. Your bank mails you a copy and sends another to the IRS, so the agency already knows about the interest before you file your return.

If you earn less than $10, your bank does not send a 1099-INT, but you still owe tax on that interest. You report it directly on your return. The $10 threshold is purely a reporting requirement — it does not create a tax-free zone for small amounts.

Some banks pay interest monthly, others quarterly, and a few still pay annually. Regardless of the payment schedule, all interest earned during the calendar year gets reported on a single 1099-INT issued in January of the following year. If you moved banks mid-year or closed an account, you may receive multiple 1099-INT forms — one from each bank where you held an account.

How your tax bracket determines what you actually pay

The federal tax rate on interest is not a flat percentage — it depends on your total income and filing status. The IRS uses tax brackets, and interest income pushes you into whichever bracket applies to your combined income. If you earn $50,000 in wages and $500 in interest, the IRS treats you as earning $50,500 total, and your interest is taxed at the marginal rate for that income level.

For 2024, federal tax brackets range from 10% to 37%. Most people fall into the 12%, 22%, or 24% brackets. If you are in the 22% bracket, you pay roughly $110 in federal tax on $500 of interest. If you are in the 12% bracket, you pay roughly $60 on the same $500. The exact amount also depends on deductions, credits, and whether you file as single, married filing jointly, or another status.

State income tax stacks on top of the federal amount. New York taxes interest at rates up to 10.9%. California taxes it up to 13.3%. Texas, Florida, and several other states do not tax interest income at all. If you live in a state with no income tax, you owe only the federal tax. If you live in a high-tax state, your total tax bill on interest can be substantial.

Interest in tax-advantaged retirement and education accounts

Interest earned inside certain accounts does not trigger immediate tax. A Roth IRA grows tax-free, meaning interest and investment gains are never taxed as long as you follow withdrawal rules. A traditional IRA defers tax until you withdraw money in retirement. A 529 education savings plan grows tax-free when used for may have access to education expenses.

These accounts exist specifically to let your interest compound without annual tax drag. If you have $10,000 earning 4% annually in a regular savings account, you pay tax on $400 each year. In a Roth IRA, that $400 grows tax-free. Over decades, the difference compounds significantly.

The tradeoff is that these accounts have contribution limits, withdrawal restrictions, or both. A Roth IRA limits how much you can contribute each year based on income. A 529 plan requires the money to be used for education or you pay tax plus a penalty on the earnings. A traditional IRA lets you contribute more but taxes withdrawals as ordinary income. Understanding which account fits your situation requires looking at your timeline and goals, not just the tax treatment of interest.

What happens if you do not report interest income

The IRS matches the 1099-INT your bank sends to the agency against your tax return. If you report $200 in interest but your bank reported $500, the IRS notices the discrepancy. The agency may send you a notice asking for the missing $300, plus interest and penalties on the unpaid tax.

Penalties for underreporting interest income typically run 20% of the unpaid tax, though they can be higher if the IRS determines the underreporting was intentional. If you owed $110 in tax on $500 of unreported interest and did not pay it, you might owe $110 plus $22 in penalties plus interest accrued since the original due date. The longer you wait to correct it, the more interest accumulates.

If you genuinely forgot to report small amounts of interest, you can amend your return using Form 1040-X. Filing an amended return before the IRS contacts you often results in lower penalties. If the IRS initiates contact first, penalties are harder to avoid.

Strategies to reduce tax on savings interest

The most direct way to reduce tax on interest is to earn less interest — which sounds obvious but matters in practice. High-yield savings accounts currently pay 4% to 5% annual interest, while traditional savings accounts at large banks pay 0.01% to 0.05%. Moving $10,000 from a traditional account to a high-yield account means earning $400 to $500 per year instead of $1 to $5. The tax on that extra $395 to $499 is real money, but so is the interest itself.

Putting money into tax-advantaged accounts reduces taxable interest directly. If you max out a Roth IRA contribution ($7,000 in 2024 for most people), that money earns interest tax-free. If you have a child and open a 529 plan, education savings grow without annual tax. These strategies work best when you have a clear timeline — retirement in 10 years, college in 5 years — because early withdrawal penalties can erase the tax benefit.

Holding bonds or bond funds in taxable accounts creates tax drag similar to savings interest, but municipal bonds issued by states and cities often pay interest that is exempt from federal tax. This strategy makes sense only if you are in a high tax bracket and have substantial money to invest. For most people with ordinary savings accounts, the simplest approach is to accept the tax as a cost of earning interest and focus on earning enough interest to make the tax worthwhile.

Reporting interest on your tax return

Interest income goes on Schedule 1 (Form 1040), which is part of your main federal tax return. You list the total interest from all sources — all your 1099-INT forms combined — on one line. If you earned interest from multiple banks, add them together and report the total.

If your total interest income exceeds $1,500, you must also file Schedule B (Interest and Ordinary Dividends), which requires you to list each source of interest separately. Most people with ordinary savings accounts stay under this threshold, so Schedule 1 alone is sufficient.

State tax returns vary by state. Some states have a separate schedule for interest income; others fold it into the main return. Your state tax form will specify where to report it. If you use tax software, it typically walks you through entering the 1099-INT information, and the software places it in the correct location on both federal and state returns.

Frequently Asked Questions

Do I have to report interest if I earned less than $10?

Yes. The $10 threshold only determines whether your bank sends a 1099-INT form. You are still required to report all interest earned, even amounts under $10. If you earned $5 in interest and no 1099-INT was issued, you report that $5 directly on your tax return.

What if I earned interest in multiple banks?

Add all the interest together and report the total on Schedule 1. If you received multiple 1099-INT forms, you do not file them all separately — you combine the amounts. If total interest exceeds $1,500, you also file Schedule B listing each bank individually.

Can I deduct the tax I pay on interest as a loss?

No. Interest income is taxed as ordinary income, and you cannot deduct the tax itself. You can deduct investment losses in some cases, but that applies to stocks, bonds, and other investments, not to interest earned on savings accounts.

Is interest taxable if I do not withdraw it from the account?

Yes. The IRS taxes interest in the year it is earned, whether you withdraw it or leave it in the account to compound. If your bank credits $100 in interest to your account on December 31, you owe tax on that $100 in that tax year, even if you never touch the money.

What states do not tax interest income?

Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming do not have state income tax at all, so interest is not taxed at the state level. New Hampshire and Tennessee tax only interest and dividend income, not wages. All other states tax interest as ordinary income at rates varying from roughly 1% to 13%.
