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

The interest your savings account earns is taxed as ordinary income, which means it uses the same tax brackets as your wages or salary. You do not pay a flat percentage on the interest itself. Instead, you add the interest to your other income for the year, and the combined total determines your tax bracket and rate.

If you earned $50,000 in wages and $200 in savings interest, the IRS treats you as having $50,200 in taxable income. That $200 gets taxed at whatever marginal rate applies to your income level — which could be 10%, 12%, 22%, or higher, depending on your filing status and total earnings.

The only exception is if your interest income is very small. If you earned less than $5 in interest during the year, you do not have to report it to the IRS, though reporting it does not hurt.

Key Takeaways

  • Savings interest is taxed as ordinary income at your marginal tax rate, which varies by your total income and filing status, not by a fixed percentage on the interest.
  • You must report all interest income of $5 or more on your tax return, even if the bank does not send you a Form 1099-INT.
  • The bank will send you a Form 1099-INT by January 31 if you earned $10 or more in interest during the year, but you are responsible for reporting smaller amounts yourself.
  • State and local income taxes also apply to savings interest in most states, adding 3% to 13% depending on where you live.
  • High-yield savings accounts earn more interest but are taxed the same way as regular savings accounts.

How your tax bracket determines what you actually pay

Your marginal tax rate — the rate applied to your last dollar of income — is what matters for savings interest. In 2024, the federal brackets for single filers range from 10% on the first $11,600 of income to 37% on income over $578,100. If you are married filing jointly, the brackets are wider.

Say you are single, earn $35,000 in wages, and have $500 in savings interest. Your total taxable income is $35,500. You fall into the 12% bracket, so that $500 interest is taxed at 12%, meaning you owe $60 in federal tax on it. If you were in the 22% bracket, the same $500 would cost you $110.

This is why high earners pay more tax on the same interest amount — not because banks charge them more, but because their marginal rate is higher. A person earning $150,000 with $500 in interest pays tax at 24%, while someone earning $30,000 pays at 12% on the same $500.

State and local taxes on savings interest

Most states tax savings interest as ordinary income, adding their own state income tax on top of federal tax. State rates range from zero in states like Texas, Florida, and Wyoming to over 13% in California and New York.

Some states offer small breaks: Illinois exempts interest income entirely, and Mississippi exempts interest on savings accounts specifically. But these are rare. In most places, you pay both federal and state tax on the full interest amount.

If you live in a state with no income tax, you still owe federal tax on savings interest. If you live in a state with income tax, you owe both. A person in California earning $500 in interest might pay roughly $60 in federal tax (at 12%) plus $65 in state tax (at 13%), totaling $125 on that $500.

When the bank reports your interest to the IRS

Banks send a Form 1099-INT to you and the IRS when you earn $10 or more in interest during the calendar year. This form arrives by January 31 and lists all interest paid by that bank. If you have accounts at multiple banks, you will receive a separate 1099-INT from each one.

You are required to report all interest income of $5 or more, even if the bank does not send a 1099-INT. If you earned $8 in interest at a small credit union that does not issue forms, you still report it on your tax return. The IRS matches 1099-INT forms to your return, so unreported interest on a 1099 will trigger a notice.

Keep your 1099-INT forms and any statements showing interest earned. You will need them to fill out your tax return or to provide to a tax preparer. The form shows the interest amount in Box 1, and that is the number you report on Schedule B (if you have more than $1,500 in interest) or directly on Form 1040 (if you have $1,500 or less).

High-yield savings accounts and tax treatment

High-yield savings accounts earn significantly more interest than traditional savings accounts — sometimes 4% to 5% annually compared to 0.01% at a regular bank. But the tax treatment is identical. That higher interest is still taxed as ordinary income at your marginal rate.

The advantage of a high-yield account is that you earn more money before taxes. The disadvantage is that you also owe more tax on it. If you earn $500 in interest at a high-yield account instead of $50 at a regular account, you pay tax on the full $500, not just the extra $450.

This matters for tax planning. Some people move money to high-yield accounts in years when their income is lower, so the interest is taxed at a lower rate. Others keep money in regular accounts in high-income years to minimize the tax hit. Neither strategy is wrong — it depends on your situation.

What to do if you did not receive a 1099-INT

If you earned $10 or more in interest and did not receive a 1099-INT by early February, contact the bank directly. Ask them to reissue the form or confirm that interest was paid. Banks sometimes delay or send forms to the wrong address.

If the bank confirms you earned interest but will not issue a form, you still report it on your tax return. Write the bank name and the interest amount on Schedule B. The IRS may follow up if the amount does not match their records, but reporting it yourself prevents penalties for unreported income.

If you earned less than $10 in interest, no 1099-INT is required, but you should still report it if it is $5 or more. Small amounts add up across multiple accounts, and the IRS expects complete reporting.

How to minimize tax on savings interest

You cannot avoid tax on savings interest, but you can reduce it by earning interest in tax-advantaged accounts. Money in a traditional IRA or 401(k) earns interest tax-free until you withdraw it. Money in a Roth IRA or Roth 401(k) earns interest tax-free permanently, as long as you follow withdrawal rules.

If you have a high income and want to save beyond retirement account limits, a 529 education savings plan allows interest to grow tax-free if used for education expenses. Otherwise, regular taxable savings accounts are your only option, and the interest is taxed annually.

Some people use savings bonds or Treasury bills as an alternative. Interest on I Bonds and Series EE Bonds is tax-deferred until you cash them in, and it may be tax-free if used for education. Treasury bills are taxed federally but not by most states. These are not better or worse than savings accounts — just different timing and tax treatment.

Frequently Asked Questions

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

You must report interest of $5 or more, even if the bank does not send a 1099-INT. Interest under $5 does not have to be reported. If you have multiple accounts, add up the interest from all of them — if the total is $5 or more, report it.

What if my savings interest pushes me into a higher tax bracket?

Interest income is added to your other income, so it can push you into a higher bracket. However, only the income in the new bracket is taxed at the higher rate. If you earn $500 in interest that moves you from the 12% bracket to the 22% bracket, only the portion of income above the bracket threshold is taxed at 22%, not all $500.

Can I deduct savings account fees from my interest income?

No. You report the full interest amount on your tax return. Fees you pay to the bank are not deductible against interest income. However, if you have significant investment expenses, you may be able to deduct them as miscellaneous itemized deductions, though this is limited and rarely worthwhile for most people.

Is interest from a money market account taxed differently?

No. Money market accounts, savings accounts, and certificates of deposit are all taxed the same way — as ordinary income at your marginal rate. The bank will send a 1099-INT if you earn $10 or more, and you report it on your tax return the same way.

What if I earned interest but the bank closed my account?

You still owe tax on the interest earned while the account was open. The bank should send a 1099-INT for the year the account was closed, showing interest through the closing date. If they do not, contact them and ask for a corrected form or a written statement of interest paid.
