The IRS taxes all savings account interest as ordinary income

Any interest your savings account earns is taxable income in the year you receive it. The IRS treats it the same way it treats wages or salary — you report it on your tax return, and you owe federal income tax on the full amount. Most banks and credit unions will send you a Form 1099-INT if your interest reaches $10 or more in a calendar year, though some institutions report even smaller amounts.

The tax you owe depends on your total income and your tax bracket for that year. Someone in the 22% tax bracket pays roughly 22 cents in federal tax for every dollar of interest earned. State and local income taxes may apply on top of that, depending on where you live. The key point: there is no threshold below which interest becomes tax-free. Even $5 in interest is technically taxable, whether or not the bank reports it.

Key Takeaways

  • All savings account interest is taxable income and must be reported on your federal tax return in the year you earn it.
  • Banks send Form 1099-INT when interest reaches $10 or more, but you owe tax on all interest regardless of whether you receive a form.
  • The tax rate on interest depends on your total income and tax bracket, ranging from 10% to 37% at the federal level.
  • High-yield savings accounts earn more interest, which means a larger tax bill — but the after-tax return is usually still higher than traditional savings accounts.
  • You can reduce taxable interest by holding savings in tax-advantaged accounts like IRAs or 529 plans, where interest grows tax-deferred or tax-free.

How the IRS counts interest income

The IRS counts interest as income in the year it is credited to your account, not when you withdraw it. If your bank credits $50 in interest on December 31, that $50 is taxable in that tax year, even if you do not touch the money until the following year. This is called the accrual method of accounting, and it applies to most consumer savings accounts.

Interest is reported under the category of unearned income on your tax return. You report it on Schedule B (Interest and Ordinary Dividends) if your total interest and dividends exceed $1,500, or directly on Form 1040 if the amount is smaller. The bank's 1099-INT form lists the exact amount they reported to the IRS, so your return should match that figure.

Form 1099-INT and reporting requirements

Banks and credit unions must issue a Form 1099-INT to you and file a copy with the IRS if you earn $10 or more in interest during the calendar year. You will receive it by January 31 of the following year. The form shows the account number, the bank's name, and the total interest paid.

If you do not receive a 1099-INT, you still owe tax on the interest. Some smaller institutions or money market funds may not issue forms for amounts under $10, but the IRS still expects you to report it. If you have multiple savings accounts at different banks, you may receive several 1099-INT forms — add them all together when you file your return. The IRS receives copies of all 1099-INT forms filed by banks, so misreporting or omitting interest income can trigger an audit notice.

Tax brackets and what you actually pay

The amount of tax you owe on interest depends on your marginal tax bracket — the rate applied to your last dollar of income. In 2024, federal tax brackets range from 10% to 37%. A single filer with $50,000 in taxable income falls in the 22% bracket, meaning interest income is taxed at 22%. A filer with $500,000 in income is in the 37% bracket.

State and local income taxes add to the federal bill. New York, California, and several other states tax interest at rates between 5% and 13%. Some states, including Florida, Texas, and Wyoming, do not tax income at all. A person in California earning $100 in savings interest might owe roughly $35 in combined federal and state tax, while someone in Texas owes only the federal portion.

High-yield savings accounts currently pay 4% to 5% APY, which sounds attractive until you factor in taxes. If you earn $500 in interest and owe 24% in combined federal and state tax, your after-tax return is $380. That is still better than a traditional savings account paying 0.01%, but it is important to know the real number you keep.

Tax-advantaged accounts that shield interest from taxes

Certain accounts allow interest to grow without annual tax bills. A traditional IRA or 401(k) defers taxes on interest until you withdraw money in retirement. A Roth IRA or Roth 401(k) lets interest grow completely tax-free if you follow withdrawal rules. A 529 education savings plan allows tax-free growth when money is used for may have access to education expenses.

Health Savings Accounts (HSAs) also grow tax-free if used for medical expenses. If you have high-deductible health insurance, an HSA can be a powerful tool — you earn interest on the balance, and that interest is never taxed as long as you spend the money on medical bills.

These accounts have contribution limits and withdrawal restrictions, so they are not a fit for all savings goals. But if you are saving for retirement or education, moving money into a tax-advantaged account can save you thousands in taxes over time compared to keeping it in a regular savings account.

What happens if you do not report interest income

The IRS matches 1099-INT forms filed by banks against the tax returns it receives. If a bank reports $500 in interest but your return shows $0, the IRS will send you a notice asking for the missing income and any unpaid tax. You will owe the tax plus interest on the unpaid amount, calculated daily from the original due date.

Penalties apply if the underreporting is deemed negligent or fraudulent. A negligence penalty is typically 20% of the unpaid tax. If the IRS determines fraud, the penalty can reach 75%. Even small amounts of unreported interest can trigger correspondence, and the cost of responding — in time, stress, or professional fees — often exceeds the tax owed.

Strategies to minimize interest tax

If you have a large savings balance earning significant interest, consider splitting it across account types. Keep emergency funds in a regular savings account or money market account. Move longer-term savings into a traditional IRA, Roth IRA, or other tax-advantaged account if you meet the contribution limits. This approach does not eliminate the tax, but it defers it or eliminates it entirely for the portion in protected accounts.

Another option is to hold savings in a taxable brokerage account invested in municipal bonds or bond funds. Municipal bond interest is exempt from federal income tax and often from state tax too, though this strategy works best for larger amounts and carries different risks than savings accounts.

For most people, the simplest approach is to accept that savings interest is taxable and factor that into your financial planning. A high-yield savings account earning 4.5% APY and taxed at 24% nets you roughly 3.4% after tax — still significantly better than a 0.01% traditional account, even after taxes.

Frequently Asked Questions

Do I have to report interest if the bank did not send me a 1099-INT?

Yes. The IRS requires you to report all interest income, even if the amount is under $10 and the bank did not issue a form. The bank's failure to send a 1099-INT does not erase your tax obligation. If the IRS discovers unreported interest later, you will owe back taxes plus penalties and interest.

Can I deduct savings account interest as a loss?

No. Interest income cannot be deducted or offset against other income. You report it as taxable income in full. The only way to reduce the tax is to earn the interest in a tax-advantaged account or to use strategies like municipal bonds, which are beyond the scope of regular savings accounts.

What if I have interest from multiple banks?

Add all 1099-INT forms together and report the total on your tax return. If you receive five forms showing $50, $75, $100, $25, and $60, you report $310 in total interest income. The IRS receives copies of all five forms, so your return must match the combined total.

Does interest from a joint account get split between owners for tax purposes?

Not automatically. The bank typically reports all interest to the Social Security number listed as the primary account holder on the 1099-INT. You and the co-owner should agree on how to split the tax liability and report it accordingly on your individual returns. If you disagree, the IRS may contact both of you to clarify.

Is interest from a savings account taxed differently than interest from a CD?

No. Both are taxed as ordinary income at your marginal tax rate. A CD earning 5% APY is taxed the same way as a high-yield savings account earning 5% APY. The only difference is timing — CD interest may be reported in the year it matures rather than the year it accrues, depending on the term and the bank's accounting method.
