The IRS counts your savings interest as income, and you report it on your tax return
Interest you earn in a high yield savings account is taxable income. The IRS treats it the same way it treats wages or salary — you owe federal income tax on the money. Your bank will send you a form at the end of the year showing how much interest you earned, and you'll report that amount when you file your taxes.
The amount of tax you actually pay depends on your total income and which tax bracket you fall into. Someone earning $30,000 a year will pay less tax on $500 of interest than someone earning $150,000. The interest itself is always taxable, but the tax rate applied to it varies.
State and local taxes may also explore, depending on where you live. Some states tax interest income, and some do not. If you live in a state with income tax, you'll typically report the same interest amount to both your state and the federal government.
Key Takeaways
- Your bank sends you a Form 1099-INT each January showing all interest earned in the previous year, and you report this amount on your federal tax return.
- Interest income is taxed at your ordinary income tax rate, which depends on your total earnings and filing status, not at a special rate.
- You only owe tax on interest actually earned and credited to your account, not on the full balance you're holding.
- If you earned less than $10 in interest during the year, your bank may not send a 1099-INT, but you still report any interest you earned.
- State income tax on savings interest varies by state — some states don't tax it at all, while others treat it like federal income.
The Form 1099-INT: what your bank sends and when
In late January or early February, your bank will mail or email you a Form 1099-INT if you earned $10 or more in interest during the previous calendar year. This form shows exactly how much interest you earned in that account. You'll receive one form for each bank or financial institution where you held an account that earned interest.
The 1099-INT has three copies: one for you, one for the IRS, and one for your state tax authority (if applicable). The bank keeps a record and sends the same information to the IRS, so the amount you report on your tax return should match what the IRS already knows about you.
If you earned less than $10 in interest, your bank typically won't send a 1099-INT. However, you are still required to report any interest you earned, even if you don't receive the form. Keep your own records of interest earned if you're below the reporting threshold.
How interest income affects your tax bracket and what you owe
Interest income is added to your other income — wages, self-employment earnings, investment gains — to calculate your total taxable income for the year. This total income determines which tax bracket you fall into and how much federal tax you owe overall.
For example, if you earned $45,000 in wages and $800 in savings interest, your taxable income is $45,800. The interest doesn't get taxed at a separate rate; it's straightforward part of your total income. If that $45,800 puts you in the 22% tax bracket (for 2024, depending on your filing status), then roughly 22% of your total income is owed in federal tax — not 22% of just the interest.
The practical effect is that earning interest in a high yield savings account can push you into a higher tax bracket if you're close to the boundary. Someone earning $46,000 in wages who then earns $5,000 in interest might move from one bracket to the next, paying a higher rate on some of their income. This is rare with savings interest alone, but it's worth understanding if you have substantial savings.
State taxes on savings interest vary widely
Some states don't tax interest income at all. Others tax it at the same rate as federal income. A few states have special rules — for instance, some exempt interest earned on certain types of savings accounts or only tax interest above a certain threshold.
If you live in a state with income tax, you'll report your interest income to that state when you file your state return. The amount is the same as what you report federally, but the tax owed may be different because state tax rates and brackets differ from federal ones. Check your state's tax authority website or ask a tax preparer about your state's specific rules.
If you live in a state with no income tax — such as Florida, Texas, or Wyoming — you won't owe state tax on your savings interest, though you'll still owe federal tax.
When you should report interest even without a 1099-INT
If you earned less than $10 in interest during the year, your bank won't send you a 1099-INT. You are still required to report that interest on your tax return. The IRS expects you to keep your own records and report all income, regardless of whether you receive a form.
Similarly, if you opened an account late in the year and earned a small amount, or if you moved money between accounts and earned interest in multiple places, make sure you're tracking all of it. Add up the interest from all your accounts and report the total.
Keeping a straightforward spreadsheet or using your bank's online statements to track interest is the easiest way to stay organized. When tax time comes, you'll have the numbers ready.
How to report interest income on your tax return
On your federal return, interest income goes on Schedule B (if you have more than $1,500 in interest and dividend income combined) or directly on Form 1040 (if you have less). You'll list each account or institution and the amount of interest earned, then add it all up and transfer the total to your main return.
If you use tax software, it will usually walk you through entering this information. If you file by hand or work with a tax preparer, bring your 1099-INT forms and any records of interest you earned below the reporting threshold.
For state taxes, follow your state's instructions. Most states have a similar process — you report interest income on a state schedule or form and include it with your state return.
The relationship between interest rates and your tax bill
Higher interest rates mean more interest earned, which means more taxable income and a larger tax bill. This is why the interest rate your bank offers matters: a high yield savings account earning 4.5% APY will generate more taxable income than one earning 0.01%, and you'll owe more tax on those earnings.
However, this doesn't mean you should avoid high yield accounts to reduce taxes. Earning $500 in interest and paying $100 in tax leaves you $400 ahead. Earning $10 in interest and paying $2 in tax leaves you $8 ahead. The tax is a cost of earning the interest, but you're still coming out ahead.
If you're in a very high tax bracket, the after-tax return on your savings is lower than the stated APY. Someone in the 37% federal tax bracket plus state taxes might keep only 55% of the interest they earn. This is worth considering if you're deciding between savings and other uses for your money, but it doesn't change the fact that interest is taxable income.
Frequently Asked Questions
Do I have to pay taxes on interest I don't withdraw?
Yes. The IRS taxes interest when it's earned and credited to your account, not when you withdraw it. If your bank credits $500 in interest on December 31, you owe tax on that $500 in that year, even if you don't touch the money until the following year.
What if I have multiple high yield savings accounts?
Each bank sends its own 1099-INT. You'll report the interest from each account separately on Schedule B (or directly on Form 1040 if your total interest is under $1,500), then add them all together for your total interest income.
Can I deduct anything to offset the interest income?
Generally, no. Interest income is added to your other income with no deduction. However, if you borrowed money to fund the savings account, you cannot deduct the interest you paid on that loan against the interest you earned — that's not how the tax code works.
What happens if I don't report the interest?
The IRS receives a copy of your 1099-INT from your bank. If you don't report the interest, the IRS will notice the discrepancy and may send you a notice asking for the tax owed, plus penalties and interest on the unpaid amount. It's much simpler to report it correctly the first time.
Does interest from a high yield savings account count as earned income?
No. Interest is considered unearned income. This matters for certain tax credits and deductions that depend on earned income, such as the Earned Income Tax Credit. However, it's still fully taxable income for federal and state purposes.
