The tax rate on your savings interest depends on your total income, not the interest amount alone

The interest your bank pays you is taxed as ordinary income, which means it gets added to your wages, self-employment earnings, and any other money you made that year. The tax rate you pay on that interest is whatever tax bracket you fall into based on your total income — not a separate rate just for interest.

If you earned $35,000 in wages and $200 in savings interest, the IRS treats that $200 as part of your $35,200 total income. You do not pay tax on the interest separately. Instead, you pay tax on all $35,200 at the rate that applies to someone in your income bracket.

For 2024, federal tax brackets range from 10% to 37%, depending on how much you earned and whether you file as single, married filing jointly, or another status. Your actual rate depends on where your total income lands, not on how much of it came from interest.

Key Takeaways

  • Savings interest is taxed as ordinary income at your regular tax bracket rate, which ranges from 10% to 37% federally depending on your total earnings.
  • You report interest on your tax return using the 1099-INT form your bank sends you, which lists all interest earned that year.
  • If you earned less than $600 in interest from one bank, that bank may not send a 1099-INT, but you still owe tax on it.
  • Some states tax interest income and some do not, so your total tax bill includes both federal and state tax where applicable.
  • High-yield savings accounts pay more interest than traditional savings accounts, which means you owe more tax on the earnings.

How your tax bracket determines what you pay

Tax brackets are ranges of income, and each range has a rate attached. When your total income (wages plus interest plus everything else) falls into a bracket, you pay that rate on the income in that bracket only — not on your entire income.

For example, in 2024, if you are single, the first $11,600 of income is taxed at 10%, the next portion up to $47,150 is taxed at 12%, and so on. If your total income is $40,000, you pay 10% on the first $11,600 and 12% on the remaining $28,400. Your savings interest of $200 falls somewhere in that $28,400 and is taxed at 12%.

The brackets change each year and differ based on your filing status. A married couple filing jointly has wider brackets than a single filer, so the same amount of interest might be taxed at a lower rate for them. The IRS publishes updated brackets every January.

What the 1099-INT form tells you and when you receive it

Your bank sends you a Form 1099-INT early in the year (usually by January 31) if you earned interest during the previous year. This form lists the total interest you earned from that bank and is the document you use to report that interest on your tax return.

If you earned less than $600 in interest from a single bank in 2024, that bank is not required to send you a 1099-INT. However, you still owe tax on that interest — you report it yourself on your return even without the form. If you have accounts at multiple banks, each one sends its own 1099-INT if the threshold is met, and you add all the interest together on your return.

The bank also sends a copy of the 1099-INT to the IRS, so the IRS knows how much interest you earned. This is why it is important to report all interest on your return, even small amounts — the IRS matches what you report to what the banks reported.

State income tax on savings interest

Most states tax interest income the same way the federal government does — as ordinary income at your state tax bracket rate. However, a few states do not have income tax at all, and some have special rules for interest.

States without income tax include Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in one of these states, you owe federal tax on your interest but no state tax. If you live elsewhere, you owe both federal and state tax on the interest.

State tax rates vary widely. Some states tax interest at rates as low as 1%, while others go as high as 13%. Your state tax bill is separate from your federal bill, and you report state interest income on your state tax return (if your state requires one).

How high-yield savings accounts change your tax bill

A high-yield savings account pays significantly more interest than a traditional savings account — sometimes 4% to 5% annually compared to 0.01% or less at a regular bank. This means you earn more money, and you owe more tax on those earnings.

If you have $10,000 in a traditional savings account earning 0.01%, you earn $1 per year and owe roughly 10 to 37 cents in federal tax depending on your bracket. The same $10,000 in a high-yield account earning 4.5% earns $450 per year, and you owe roughly $45 to $166 in federal tax. The higher interest is real money in your pocket, but the tax bill is real too.

This does not mean high-yield accounts are a bad choice — you still come out ahead. But when you are deciding where to keep your money, remember that the interest you earn is taxable income, and the higher the rate, the more you owe.

Reporting interest on your tax return

When you file your federal tax return, you report all interest income on Schedule B (if you have more than $1,500 in interest or dividends) or directly on Form 1040 (if you have $1,500 or less). You list each 1099-INT you received and add up the total interest.

That total gets transferred to your main tax form, where it is added to your other income to calculate your total income and your tax bracket. You do not calculate tax on the interest separately — it all gets combined.

If you use tax software, it usually walks you through entering the 1099-INT information, and the software calculates where it fits in your brackets. If you file by hand or with a tax professional, they handle this step for you.

What happens if you do not report interest income

The IRS receives a copy of every 1099-INT your bank sends you. If you do not report the interest on your return, the IRS will notice the mismatch between what you reported and what the bank reported. This can trigger a notice asking you to explain the difference or pay the tax you owe plus penalties and interest.

Even small amounts of unreported interest can cause problems. It is simpler and cheaper to report it correctly the first time. If you are unsure whether you need to report interest, a tax professional or the IRS website can clarify based on your situation.

Frequently Asked Questions

Do I owe tax on interest if I earned less than $600?

Yes. The $600 threshold only determines whether your bank sends you a 1099-INT form. You still owe tax on all interest you earned, even if it is $50 or $100. You report it on your return yourself if you do not receive a form.

Can I deduct savings account fees from my interest income?

No. You report the full interest amount on your return. Fees you pay to the bank are not deductible against interest income for most taxpayers. You pay tax on the interest and the fees come out of your own money.

What if I moved money between banks during the year?

Each bank reports only the interest it paid you while you had money there. If you earned $100 at Bank A and $50 at Bank B, you receive two 1099-INT forms and report a total of $150 on your return. You add them all together.

Does interest from a money market account get taxed differently?

No. Money market accounts, savings accounts, and certificates of deposit all report interest on 1099-INT forms and are all taxed as ordinary income at your regular tax bracket rate. The account type does not change the tax treatment.

What if I earned interest in a joint account with someone else?

The bank reports the full interest amount on a 1099-INT. You and the other account holder need to decide how to split it for tax purposes — usually 50/50 unless you have a different agreement. Each person reports their share on their own tax return.
