Interest from your savings account counts as taxable income

The interest your bank pays you on a savings account is taxable income. The IRS treats it the same way it treats wages or freelance earnings — you owe federal income tax on the full amount. Most banks will send you a Form 1099-INT in January showing how much interest you earned the previous year, and you report that figure on your tax return.

The amount of tax you actually pay depends on your total income and your tax bracket, not on the interest amount alone. Someone in the 12% tax bracket pays roughly 12 cents in federal tax per dollar of interest earned. Someone in the 37% bracket pays roughly 37 cents per dollar. State income tax, where it exists, adds on top of that.

The threshold for receiving a 1099-INT is $10 of interest in a calendar year. If you earned less than that, the bank does not have to send you a form, but you still owe tax on the interest if you file a return.

Key Takeaways

  • All savings account interest is taxable federal income, reported on Form 1099-INT if you earned $10 or more in a year.
  • The tax you owe is calculated at your marginal tax rate — the rate that applies to your highest income bracket.
  • State income tax applies to savings interest in most states, adding to your federal tax bill.
  • High-yield savings accounts earn more interest but also generate larger tax bills, so the after-tax return matters more than the advertised rate.
  • You can reduce taxable interest by holding savings in certain retirement accounts like IRAs or 401(k)s, where interest grows tax-deferred.

How the IRS knows about your interest earnings

Banks report interest to both you and the IRS using Form 1099-INT. You receive a copy by January 31 each year for the previous calendar year. The bank files the same information with the IRS, so if you do not report the interest on your tax return, the IRS will notice the mismatch.

The $10 threshold means small accounts often fly under the reporting requirement. If you have $500 in a savings account earning 0.01% annually, you earn 5 cents — no form required. But if you have $10,000 in a high-yield account earning 4.5%, you earn $450 and will receive a 1099-INT. You still owe tax on amounts under $10 if you file a return, but the bank has no obligation to report it.

Some banks offer multiple accounts or products. Each one that generates $10 or more in interest gets its own 1099-INT, so you may receive several forms from the same institution.

What your tax bracket means for savings interest

Your marginal tax rate — the percentage you pay on your last dollar of income — determines how much tax you owe on interest. This is not the same as your overall tax rate. If you are single and earned $50,000 in wages, you fall into the 22% tax bracket for 2024. Any interest you earn gets taxed at 22%, not at a lower rate.

The brackets change each year and depend on your filing status. A married couple filing jointly has higher brackets than a single filer, so the same $1,000 in interest might be taxed at 12% for the couple but 22% for a single person. The IRS publishes updated brackets every January.

This is why high-yield savings accounts can feel less attractive than they look. A 4.5% rate sounds good until you realize that 22% of the interest goes to taxes, leaving you with roughly 3.5% after tax. The math changes if you are in a lower bracket or if you hold the account in a tax-deferred retirement account.

State income tax on savings interest

Most states tax savings interest the same way the federal government does — as ordinary income at your state tax rate. Nine states have no income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only interest and dividends, not wages). If you live in one of these states, you owe only federal tax on your savings interest.

In states with income tax, the rate varies. New York charges up to 10.9% on top of federal tax. California charges up to 13.3%. A resident of California earning $1,000 in savings interest might owe roughly $350 in combined federal and state tax, depending on their bracket. A resident of Florida owes only the federal portion.

Some states offer small deductions or exemptions for interest income, but these are rare and usually explore only to residents over a certain age or with very low incomes. Check your state's tax authority website to see whether your state taxes savings interest and at what rate.

How to report savings interest on your tax return

When you file your federal return, you report the interest from your 1099-INT on Schedule B (Interest and Ordinary Dividends), then transfer the total to line 1b of Form 1040. If you have less than $1,500 in total interest and dividends, you can skip Schedule B and report the amount directly on Form 1040, but most people use the schedule to keep their records organized.

You need the exact amount from your 1099-INT. If you received multiple forms from different banks, add them all together. If a bank made an error on the form, contact them to request a corrected 1099-INT (called a corrected 1099-INT) before you file.

For state taxes, you typically report the same interest amount on your state return. Some states use the federal amount as a starting point; others require you to list it separately. Check your state's tax form instructions — most state revenue websites have worksheets that walk you through the process.

Ways to reduce the tax impact of savings interest

The most direct way to avoid tax on savings interest is to hold the money in a tax-deferred retirement account like a traditional IRA or 401(k). Interest earned inside these accounts is not taxed until you withdraw the money in retirement, and withdrawals may be taxed at a lower rate. A Roth IRA or Roth 401(k) lets the interest grow tax-free forever if you follow the withdrawal rules.

If you have already maxed out retirement account contributions, you can reduce taxable interest by keeping less money in savings. This sounds obvious, but it matters: $10,000 earning 4.5% generates $450 in taxable interest. The same $10,000 in a money market fund or short-term bond fund might generate a lower return but could be more tax-efficient depending on the fund structure and your situation.

You cannot avoid tax on savings interest by not reporting it. The IRS matches 1099-INT forms to tax returns, and underreporting interest is a common audit trigger. If you owe tax and do not pay it, penalties and interest accumulate quickly.

The difference between savings interest and investment income

Savings account interest is always taxed as ordinary income at your full marginal rate. This is different from long-term capital gains (profits from selling stocks or funds held over a year), which are taxed at lower rates: 0%, 15%, or 20% depending on your income. It is also different from may have access to dividends, which get the same preferential rates as long-term gains.

This is why some people move money from savings into investment accounts once they have built an emergency fund. A dollar of interest in a savings account might be taxed at 22%, but a dollar of long-term capital gains might be taxed at 15%. Over time, the tax difference adds up. However, investment accounts carry risk — your principal can go down — while savings accounts do not.

Money market funds and bond funds sit in the middle. They generate interest-like income that is taxed as ordinary income, but some bond funds can be more tax-efficient than savings accounts because they hold longer-term bonds. This is a conversation to have with a tax professional if you have substantial savings.

Frequently Asked Questions

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

The bank does not have to send you a 1099-INT for amounts under $10, but you still owe tax on the interest if you file a return. Report it on Schedule B or directly on Form 1040, depending on your total interest and dividend income. The IRS does not know about it unless you report it, but underreporting is risky.

What if my bank sent me a 1099-INT with the wrong amount?

Contact the bank and ask for a corrected 1099-INT. They will issue a new form marked "corrected" and file it with the IRS. Do not file your tax return until you have the corrected form — if you report a different amount than what the bank reported, you will trigger an IRS notice.

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

No. You report the full interest amount on your tax return. Savings account fees are not deductible for most people. If the fees are large enough to matter, switching to a bank with lower fees is usually more effective than trying to deduct them.

Does a joint savings account change how I report interest?

The bank reports the full interest amount on a single 1099-INT. If the account is jointly owned, you and the other owner need to decide how to split the interest for tax purposes — usually 50/50, but it depends on your ownership agreement. Both of you report your share on your individual tax returns.

Is interest from a CD taxable the same way as savings account interest?

Yes. CDs generate interest income that is taxed as ordinary income at your marginal rate, reported on Form 1099-INT the same way as savings account interest. The only difference is that CD interest is often paid at maturity rather than monthly, so you might receive one larger 1099-INT instead of several smaller ones.
