Interest from savings accounts counts as taxable income
Yes, you owe federal income tax on the interest your high-yield savings account earns. The IRS treats savings account interest the same way it treats wages or other income—you report it on your tax return and pay tax at your ordinary income tax rate, which depends on your total income and filing status.
The bank or financial institution holding your account will send you a Form 1099-INT each January if you earned $10 or more in interest during the previous year. You use this form to report the interest on your federal tax return. Some states also tax savings interest, though the rules vary by state.
The amount you owe in tax depends on your tax bracket. If you're in the 22% federal tax bracket and earn $500 in interest, you'll owe roughly $110 in federal tax on that interest alone (before any state tax). The higher your total income, the higher your tax bracket and the more tax you pay on the interest.
Key Takeaways
- The IRS requires you to report savings account interest as income on your tax return, and you pay tax at your ordinary income tax rate.
- Banks send Form 1099-INT when interest reaches $10 or more in a calendar year, and you must include this on your federal return.
- Your tax rate on interest depends on your total income and filing status—higher earners pay a larger percentage of their interest in tax.
- Some states tax savings interest and some do not; check your state's rules or ask your tax preparer about your specific situation.
- Interest earned in a traditional IRA or 401(k) is not taxed until you withdraw money, but interest in a regular savings account is taxed every year.
How the IRS knows about your interest income
Your bank reports interest to the IRS automatically. When you open a savings account, you provide your Social Security number or tax ID. The bank uses this to file Form 1099-INT with the IRS and send you a copy. The IRS matches the 1099-INT to your tax return, so if you don't report the interest, the IRS will notice the discrepancy.
You must report all interest income, even if the bank doesn't send you a 1099-INT. If you earned less than $10 in interest, the bank may not issue a form, but you still owe tax on that amount. Keep your own records of interest earned if you think the amount might be close to the $10 threshold.
What happens if you don't report the interest
If you fail to report savings account interest on your tax return, the IRS will eventually catch it. When the IRS receives the 1099-INT from your bank and your tax return doesn't match, they send a notice asking for the missing income. You'll owe the tax you should have paid, plus interest on that unpaid tax, plus a penalty for underpayment.
The penalty for not reporting income is typically 20% of the unpaid tax, though it can be lower if you have reasonable cause. The interest compounds daily, so the longer you wait to correct the error, the more you owe. It's far cheaper to report the interest when you file than to deal with an IRS notice later.
Tax-advantaged accounts that shield interest from annual tax
If you want to earn interest without paying tax on it every year, you have other options. A traditional IRA or 401(k) allows interest to grow tax-deferred—you don't pay tax on the interest until you withdraw the money in retirement. A Roth IRA lets interest grow tax-free, meaning you never pay tax on the interest if you follow the withdrawal rules.
These accounts have annual contribution limits and withdrawal restrictions, so they're not a replacement for a regular savings account. But if you have money you won't need for several years, moving some of it into a tax-advantaged account can reduce your annual tax bill. A tax preparer can help you figure out whether this makes sense for your situation.
A 529 college savings plan also grows interest tax-free if the money is used for education expenses. Some states offer a state income tax deduction for 529 contributions, which can further reduce your tax bill.
State income tax on savings interest
Most states that have an income tax also tax savings account interest at your state income tax rate. A few states—including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming—have no state income tax at all, so residents of those states pay only federal tax on interest.
Some states exempt interest income for people over a certain age or with income below a threshold. New Hampshire and Tennessee tax interest and dividends but not wages. Check your state's tax website or ask a tax preparer whether your state taxes savings interest and whether any exemptions explore to you.
How to reduce the tax hit from high-yield savings
You can't avoid tax on savings interest, but you can manage how much interest you earn and therefore how much tax you owe. Keeping money in a regular savings account with a low interest rate means less interest income and less tax. However, this strategy costs you money in foregone interest, so it only makes sense if you're in a very high tax bracket and have other places to put your cash.
A more practical approach is to use a mix of accounts. Keep an emergency fund in a high-yield savings account for quick access. Put longer-term money into a traditional IRA, Roth IRA, or 529 plan where interest grows tax-deferred or tax-free. Spread money across multiple accounts if you're close to a tax bracket threshold, though the tax savings from doing this are usually small.
If you're self-employed or have investment income, you may be able to deduct certain expenses that reduce your taxable income overall, which lowers the tax you pay on interest. A tax preparer can review your situation and suggest strategies that fit your circumstances.
Frequently Asked Questions
Do I have to report interest if I earned less than $10?
Yes. The $10 threshold is when the bank must send you a Form 1099-INT, but you must report all interest income on your tax return, even if it's $1. Keep your own records of interest earned so you can report the correct amount.
What if I have multiple savings accounts at different banks?
Each bank reports interest separately on its own Form 1099-INT. You receive a 1099-INT from each institution and must add up all the interest from all your accounts when you report it on your tax return. The IRS receives all the 1099-INTs and cross-checks them against your return.
Can I deduct savings account interest as a business expense?
No. Interest earned on a personal savings account is income, not a deductible expense. If you have a business account and earn interest on business funds, that interest is still taxable income to your business, though it may be reported differently on your business tax return.
Does a Roth IRA savings account avoid all taxes on interest?
A Roth IRA avoids federal and state income tax on interest if you follow the withdrawal rules—you must be at least 59½ and have held the account for at least five years to withdraw earnings tax-free. If you withdraw early, you may owe tax and a 10% penalty on the earnings, though not on your contributions.
What if my bank reports the wrong amount of interest on the 1099-INT?
Contact your bank when ready and ask them to issue a corrected Form 1099-INT. Once you receive the corrected form, file an amended tax return if you've already filed. Keep documentation of the correction in case the IRS questions the discrepancy.
