Yes, you owe federal income tax on savings account interest, but the amount depends on how much interest you earned and your total income

The IRS treats savings account interest as ordinary income. That means if your bank paid you interest on your savings, you report it on your federal tax return just like wages or salary. You will owe tax on that interest at your regular income tax rate — whether that is 10%, 12%, 22%, or higher, depending on your tax bracket.

The bank will send you a Form 1099-INT in January if you earned $10 or more in interest during the year. That form tells you exactly how much interest the IRS knows about. You report that amount on your tax return, and the IRS cross-checks it against what the bank reported. If you earned less than $10, the bank does not have to send a form, but you still owe tax on that interest if you file a return.

State income tax works the same way in most states — you owe tax on savings interest there too. A handful of states (Illinois, Mississippi, and a few others) do not tax interest income at all, but most do. Check your state's tax agency website to see whether your state taxes savings interest.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your federal tax rate, and you report it on your tax return every year.
  • Your bank sends you a Form 1099-INT in January if you earned $10 or more in interest, and the IRS receives a copy of that form.
  • Most states tax savings interest the same way the federal government does, though a few states do not tax interest income at all.
  • You can reduce the tax you owe on savings by keeping money in accounts that earn little or no interest, or by using tax-advantaged accounts like IRAs or 529 plans if you meet the rules.

How much interest triggers a tax bill

There is no minimum amount of interest that makes you owe federal tax. If you earned $1 in interest, you technically owe tax on it. In practice, you only have to file a federal return if your total income exceeds a threshold — for 2024, that threshold is $14,600 for a single person under 65, and higher if you are married or older. If your only income is $5 in savings interest and you earned nothing else, you probably do not have to file. But if you earned $5 in interest plus $14,000 in wages, you must file and report the interest.

The bank's threshold is different. Banks only send a Form 1099-INT if you earned $10 or more in interest at that bank during the year. If you have accounts at multiple banks and earned $8 at one and $7 at another, neither bank sends a form — but you still owe tax on all $15 if your total income requires you to file.

High-yield savings accounts currently pay 4% to 5% annual interest, so even a modest balance generates taxable income. A $10,000 balance at 4.5% interest earns $450 per year in taxable interest. A $50,000 balance earns $2,250. That interest gets added to your other income and taxed at your marginal rate.

When you do not owe tax on savings interest

You do not owe tax on interest earned in a Roth IRA or Roth 401(k), as long as you follow the withdrawal rules. Interest in these accounts grows tax-free, and you do not report it on your tax return. The same is true for a 529 college savings plan — interest earned stays in the account tax-free as long as you use the money for may have access to education expenses.

Interest in a traditional IRA is also not taxed while it sits in the account, but you will owe tax on it when you withdraw the money in retirement. A Health Savings Account (HSA) works the same way — interest grows tax-free, and you owe no tax if you withdraw it for may have access to medical expenses.

Regular savings accounts, money market accounts, and certificates of deposit (CDs) all generate taxable interest. There is no way around reporting it if you file a tax return and your total income is high enough to require filing.

How to report savings interest on your tax return

When you file your federal return, you report interest income on Schedule B (if you use the long form) or directly on your 1040 (if you use the short form). The IRS form you use depends on how much interest you earned and whether you have other investment income. If you use tax software like TurboTax or TaxAct, the software walks you through entering the interest amount from your Form 1099-INT.

You enter the total interest from all your accounts in one place. If you earned $450 in interest at Bank A and $200 at Bank B, you report $650 total. The IRS already knows about the $450 because Bank A sent a Form 1099-INT, but it only knows about the $200 if Bank B sent one. Either way, you report both amounts.

For your state return, you usually report the same interest amount on your state tax form. Some states have a separate line for interest income; others fold it into total income. Your state tax software or instructions will show you where to enter it.

What happens if you do not report savings interest

If the IRS receives a Form 1099-INT from your bank but you do not report that interest on your return, the IRS will notice the mismatch. The agency cross-checks all 1099 forms against tax returns. If you earned $450 in interest and did not report it, the IRS may send you a notice asking why, or it may simply assess the tax you owe plus penalties and interest.

The penalty for underreporting income is usually 20% of the underpaid tax, plus interest that accrues from the original due date. If you owed $100 in tax on $450 in interest and did not report it, you could end up owing $120 or more by the time interest is added. The longer you wait to correct it, the more interest accumulates.

If you intentionally hide interest income, the IRS can treat it as tax fraud, which carries steeper penalties and potential criminal charges. In practice, most unreported interest is caught through the 1099 matching process, not through investigation.

Strategies to reduce tax on savings interest

The most straightforward way to reduce tax on savings interest is to keep less money in taxable savings accounts. If you have $100,000 earning 4.5% interest, you owe tax on $4,500 per year. If you move $50,000 into a Roth IRA or 529 plan (if you meet the rules), you only owe tax on $2,250.

You can also look for banks offering lower interest rates in exchange for other benefits, though this rarely makes sense — a 4.5% rate that is taxed is still better than a 1% rate that is not. A more practical approach is to use tax-advantaged accounts first (max out your IRA or 401(k) contributions) and keep only emergency funds in regular savings.

If you are in a very low tax bracket, you might owe little or no tax on interest income. Single filers under 65 with less than $14,600 in total income do not have to file a federal return at all. If you are retired and living on Social Security, your interest income might not push you over the filing threshold. Check the IRS filing requirements for your situation before assuming you have to report interest.

State taxes on savings interest

Most states tax savings interest the same way the federal government does — as ordinary income at your state tax rate. Your state tax rate is usually lower than your federal rate (ranging from 1% to 13% depending on the state), so state tax on interest is typically smaller than the federal bill.

A few states do not tax interest income at all. Illinois, Mississippi, and Tennessee do not tax interest or dividend income. If you live in one of these states, you still owe federal tax on savings interest, but you skip the state tax. Some states also offer tax breaks for interest earned in certain types of accounts (like municipal bonds), but regular savings account interest does not may have access to.

If you move to a new state during the year, you may owe tax to both states on interest earned while you lived in each one. The rules for apportioning income between states vary, so check with your new state's tax agency if you relocated mid-year.

Frequently Asked Questions

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

You do not have to file a federal return if your total income is below the threshold for your filing status, even if you earned $1 in interest. But if you earned $1 in interest plus $14,000 in wages, you must file and report the interest. The $10 threshold is only what banks use to decide whether to send a Form 1099-INT.

What if I earned interest in multiple savings accounts?

You add up all the interest from all your accounts and report the total on your tax return. Each bank that paid you $10 or more sends a separate Form 1099-INT, but you combine all of them into one line item on your return. The IRS knows about the interest the banks reported, so report all of it.

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

No. You report the gross interest the bank paid you, not the interest minus fees. If your bank charged you $50 in fees and paid you $100 in interest, you report $100 as income. You cannot deduct the fees against the interest on your tax return.

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

No. Money market accounts, savings accounts, and CDs all generate interest that is taxed as ordinary income. The tax treatment is the same regardless of the account type. The only difference is how much interest each account pays.

What if my bank made an error on my Form 1099-INT?

Contact the bank and ask them to issue a corrected Form 1099-INT (marked as a correction). The bank will send the corrected form to you and the IRS. If you already filed your return with the wrong amount, you can file an amended return (Form 1040-X) once you receive the corrected form.
