Yes, you owe federal income tax on all interest your savings account earns

The interest a high interest savings account generates is taxable income. The IRS treats it the same way it treats wages or other money you receive—you must report it on your tax return and pay federal income tax on it. Many states also tax savings account interest as part of your state income tax. The bank or financial institution holding your account will send you a form showing how much interest you earned during the year, and that amount becomes part of your taxable income.

This applies regardless of how small the interest payment is. Even if your account earned $5 in interest over the year, that $5 is taxable. The tax you owe depends on your overall income and tax bracket, not on the size of the interest payment itself.

Key Takeaways

  • Banks report savings account interest to the IRS on Form 1099-INT, and you must include that amount on your tax return.
  • The tax rate you pay on interest income depends on your federal tax bracket, which ranges from 10% to 37% depending on your total income.
  • Most states tax savings account interest as ordinary income, though a few states do not tax interest income at all.
  • You may owe taxes on interest even if the bank has not yet sent you the 1099-INT form, because the interest accrues when it is credited to your account.

How banks report your interest to the IRS

Your bank will issue you a Form 1099-INT if you earned $10 or more in interest during the calendar year. This form lists the total interest paid to your account and is sent to both you and the IRS by January 31 of the following year. Even if you do not receive a 1099-INT because your interest was under $10, you still owe tax on whatever you earned.

The 1099-INT shows interest from all accounts you hold at that bank. If you have multiple savings accounts at different banks, each bank sends its own 1099-INT. You must add up all the interest from all your 1099-INT forms and report the total on your tax return, typically on Schedule B (Interest and Ordinary Dividends) if your interest income exceeds $1,500, or directly on Form 1040 if it is $1,500 or less.

The bank reports the interest based on when it was credited to your account, not when you withdraw it. If interest posts on December 31, it counts as income for that tax year even if you do not touch the money until the following year.

What tax rate applies to your interest income

Savings account interest is taxed as ordinary income, meaning it is taxed at your regular federal income tax rate. Your federal tax bracket depends on your total income for the year. If you earn $11,000 in wages and $500 in interest, your taxable income is $11,500, and the interest is taxed at whatever bracket that $11,500 falls into.

Federal tax brackets for 2024 range from 10% to 37%, depending on your filing status and total income. A person in the 22% bracket pays 22 cents in federal tax on every dollar of interest earned. A person in the 37% bracket pays 37 cents per dollar. This is different from long-term capital gains, which have their own lower tax rates—interest income does not receive that preferential treatment.

Your state may also tax the interest. Most states treat savings account interest as ordinary income and tax it at their state income tax rate, which varies by state from roughly 1% to 13%. A handful of states—including Illinois, Mississippi, and Tennessee—do not tax interest income at all, though they may tax other types of income.

When you owe taxes on interest that has not been paid yet

You owe federal income tax on interest in the year it is credited to your account, not in the year you withdraw it or spend it. If your account earns interest monthly and that interest posts on the last day of each month, you owe tax on all twelve months of interest for that year, even if you leave the money untouched.

This matters most if you close an account partway through the year. Interest that posts before you close the account is taxable for that year. Interest that would have posted after closure is not your responsibility. If you are unsure whether interest has posted, check your account statement or contact the bank—the posting date is what matters to the IRS, not the date you notice it.

How to report interest income on your tax return

If your total interest income from all sources is $1,500 or less, you report it directly on Form 1040, line 1b. If it exceeds $1,500, you must use Schedule B to itemize each source of interest and then transfer the total to Form 1040. You will need your 1099-INT forms in front of you to fill out either form accurately.

If you have interest income but did not receive a 1099-INT (because it was under $10 or the bank made an error), you still report it. Keep your account statements as proof. The IRS may not know about small amounts of unreported interest, but reporting it protects you from penalties if the bank later corrects its records or if you are audited.

If you file electronically, tax software will usually walk you through entering 1099-INT information. If you file by paper, write the amounts in the spaces provided on Schedule B or Form 1040, depending on your total interest income.

Strategies to reduce taxes on savings account interest

You cannot avoid the tax, but you can reduce the amount of interest you earn and therefore the tax owed. Keeping money in a regular savings account that earns little to no interest means less taxable income. However, this trade-off usually costs you more in lost earnings than you save in taxes.

A more practical approach is to hold savings in tax-advantaged accounts if you are saving for a specific purpose. Money in a Roth IRA or Roth 401(k) grows tax-free and withdrawals in retirement are not taxed. Money in a traditional IRA or 401(k) grows tax-deferred, meaning you do not pay tax on the interest until you withdraw it in retirement. A 529 college savings plan allows interest to grow tax-free if used for education expenses. These accounts have contribution limits and withdrawal rules, so they work best if you are already planning to save for retirement or education.

For money you need to keep accessible, a high interest savings account still makes sense despite the tax. The interest rate is high enough that even after taxes, you come out ahead compared to a regular savings account. The tax is simply the cost of earning that interest.

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 tax return, the IRS will likely catch the discrepancy when it matches your return against the 1099-INT. This can trigger an audit notice or a bill for back taxes plus penalties and interest.

The penalty for not reporting income is typically 20% of the unpaid tax, plus interest that accrues from the original due date. If the underreporting is deemed intentional fraud rather than an honest mistake, penalties can reach 75%. Even small amounts of unreported interest can trigger correspondence from the IRS, which costs time and stress to resolve.

Reporting the interest, even if it is a small amount, is simpler and cheaper than dealing with the IRS later. If you made a mistake on a prior year return, you can file an amended return (Form 1040-X) to correct it.

Frequently Asked Questions

Do I owe taxes on interest if I earned less than $10?

Yes. The $10 threshold only determines whether the bank must send you a 1099-INT form. You still owe tax on any interest you earned, even if it is $1 or $5. Keep your account statements as proof of the amount.

Can I deduct the taxes I pay on savings account interest?

No. Interest income is added to your taxable income, and you pay tax on it at your regular rate. You cannot deduct the tax itself. However, if you paid investment fees to earn that interest, some of those fees may be deductible under certain circumstances—consult a tax professional about your specific situation.

What if I moved money between banks during the year?

Each bank reports only the interest it paid you while you held an account there. If you had $10,000 at Bank A for six months earning interest, then moved it to Bank B for six months, Bank A sends a 1099-INT for its six months of interest and Bank B sends a separate 1099-INT for its six months. You report both on your tax return.

Do I owe taxes on interest if I have not withdrawn the money yet?

Yes. The moment interest is credited to your account, it becomes taxable income for that year. You do not have to withdraw it or spend it for the tax to apply. The tax is based on when the interest posts, not when you use the money.

Is there a way to earn interest without paying taxes on it?

Regular savings accounts and high interest savings accounts are always taxable. Tax-free interest growth happens in retirement accounts like Roth IRAs or 529 plans, but these have contribution limits and rules about when you can withdraw the money. For accessible savings, you will pay tax on the interest earned.
