Banks do not tax your savings account directly, but they report the interest you earn to the IRS, and you owe federal income tax on that interest

Your bank does not take a tax cut from your account balance or charge you a tax fee. What happens instead is this: when your savings account earns interest, the bank sends a record of that interest to both you and the IRS on a form called a 1099-INT. You then report that interest as income on your federal tax return, and you pay income tax on it at your regular tax rate.

The amount of interest you earn depends on your account's interest rate and your balance. A savings account earning 4% annual interest on $10,000 generates $400 in taxable interest. A savings account earning 0.01% on the same balance generates $1 in taxable interest. The bank does not withhold this tax automatically — you owe it when you file your return.

Some states also tax savings account interest as part of state income tax. A few states do not tax interest income at all. Your state's rules are separate from federal tax, so you may owe both.

Key Takeaways

  • Banks report savings account interest to the IRS on Form 1099-INT, and you report that interest as income on your tax return.
  • You pay federal income tax on savings interest at your regular tax rate, which varies based on your total income and filing status.
  • Most banks do not withhold tax from interest automatically, so you owe the full amount when you file your return.
  • Some states tax savings interest and some do not, so check your state's rules in addition to federal requirements.
  • Interest earned in a traditional IRA or Roth IRA is not taxed the same way as interest in a regular savings account.

When you receive a 1099-INT and what it means

Your bank sends you a 1099-INT by January 31 each year if you earned $10 or more in interest during the previous calendar year. The form shows the total interest your account generated. You receive one copy and the IRS receives another.

The 1099-INT is not a bill — it is a record. You use it to fill out your tax return. If you earned interest from multiple banks or accounts, you will receive multiple 1099-INT forms, one from each institution. You add all the interest together and report the total on your return.

If you earned less than $10 in interest, the bank does not send a 1099-INT, but you still owe tax on that interest if you are required to file a return. Keep your own records of small amounts of interest.

How much tax you owe on savings interest

The tax you owe on savings interest depends on your tax bracket, which is determined by your total income for the year and your filing status. If you earn $35,000 a year and file as single, you are in a different tax bracket than someone earning $100,000. The interest is taxed at your marginal rate — the rate that applies to your highest income.

For example, if you are in the 22% federal tax bracket and earn $500 in savings interest, you owe approximately $110 in federal tax on that interest. If you are in the 12% bracket, you owe approximately $60. The IRS does not calculate this for you — you report the interest on your return, and the tax is part of your total tax bill.

State income tax works the same way. If your state taxes interest and your state tax rate is 5%, you owe an additional $25 on that $500 in interest. Some states have no income tax at all, so residents owe nothing to the state.

Savings accounts versus tax-advantaged accounts

Interest earned in a regular savings account is always taxable. Interest earned in a traditional IRA or Roth IRA is not taxed the same way. In a traditional IRA, interest compounds tax-free while the money is in the account, and you pay tax when you withdraw it. In a Roth IRA, interest compounds tax-free and you pay no tax on withdrawals in retirement, provided you follow the rules.

A high-yield savings account (HYSA) earns more interest than a regular savings account, but the interest is still fully taxable at your regular rate. The higher interest rate does not change the tax treatment. A money market account works the same way — all interest is taxable.

If you want to reduce the tax you owe on savings, moving money to a tax-advantaged account like an IRA is one option, but you must meet income limits and contribution limits set by the IRS. A financial advisor or tax professional can help you understand whether this makes sense for your situation.

What happens if you do not report savings interest

The IRS receives a copy of every 1099-INT your bank sends. If you do not report the interest on your return, the IRS will notice the discrepancy. The agency matches 1099 forms to tax returns automatically.

Failing to report interest can result in penalties and interest charges on the unpaid tax. The penalty is typically 20% of the unpaid tax, plus interest that compounds daily. If the IRS determines the omission was intentional, the penalty can be higher. It is much cheaper to report the interest, even if you owe tax on it.

If you made an honest mistake and did not report interest in a prior year, you can file an amended return using Form 1040-X. The sooner you correct it, the lower the interest charges will be.

State-by-state differences in interest taxation

Most states that have an income tax also tax interest income. However, a few states do not tax interest at all. Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming have no state income tax. If you live in one of these states, you owe federal tax on savings interest but no state tax.

Other states have special rules. Some tax interest but not dividends, or vice versa. Some offer a small deduction for interest income. Illinois does not tax interest or dividends at all, even though it has an income tax. You need to check your specific state's rules, which you can find on your state's department of revenue website.

If you moved during the year, you may owe tax to two states. The state where you lived on December 31 is the one that taxes your full-year income. States have different rules for part-year residents, so check both your old and new state's requirements.

Reporting interest on your tax return

You report savings interest on Schedule B (Interest and Ordinary Dividends) if your interest income is more than $1,500, or directly on Form 1040 if it is $1,500 or less. You list each 1099-INT separately, or you can total them if you have multiple accounts.

The interest amount from your 1099-INT goes into the "Interest Income" section of your return. This is added to your other income (wages, self-employment income, capital gains, and so on) to calculate your total taxable income. Your tax is then calculated based on that total.

If you use tax software, it will walk you through entering the 1099-INT information. If you file by hand or work with a tax professional, bring all your 1099-INT forms with you.

Frequently Asked Questions

Do I have to pay tax on savings interest if I earned very little?

Yes, if you are required to file a tax return, you must report all interest income, even small amounts. However, if your total income is below the filing threshold for your age and filing status, you may not be required to file at all. Check the IRS website for current income thresholds.

Can I avoid taxes by keeping my savings account balance low?

You cannot avoid tax by keeping a low balance — you owe tax on whatever interest you earn, regardless of the amount. However, lower balances do earn less interest, which means less tax. Moving money to a tax-advantaged account like an IRA is a better strategy if you want to reduce taxable interest.

What if my bank did not send me a 1099-INT but I earned interest?

If you earned $10 or more in interest and did not receive a 1099-INT by January 31, contact your bank. If the bank confirms you earned interest, ask for a corrected form. If you earned less than $10, keep your own records and report the interest on your return anyway.

Is interest from a money market account taxed differently than interest from a savings account?

No, both are taxed the same way. Money market accounts typically earn higher interest rates, but the interest is fully taxable at your regular income tax rate, just like savings account interest.

Do I owe tax on interest if I moved the money to a different bank during the year?

Yes, you owe tax on all interest earned during the year, regardless of which bank held the money or when you moved it. Each bank reports only the interest earned while your money was with them, so you may receive multiple 1099-INT forms. Add them all together and report the total.
