The IRS taxes savings account interest as ordinary income in the year you earn it

Interest from a high-yield savings account is taxed the same way as wages or salary — at your full ordinary income tax rate, which depends on your tax bracket. The bank reports what you earned to the IRS on a 1099-INT form, and you report that same amount on your tax return. There is no special rate for savings interest, no waiting period, and no threshold below which it escapes taxation.

The timing matters: you owe tax on interest in the year the bank credits it to your account, even if you do not withdraw the money. If your account earned $500 in interest during 2024, that $500 is taxable income for the 2024 tax year, due when you file in 2025.

The amount you owe depends entirely on your tax bracket. Someone in the 22% bracket pays roughly $110 in federal tax on that $500 in interest. Someone in the 37% bracket pays roughly $185 on the same $500. State and local income tax may explore on top of that, depending on where you live.

Key Takeaways

  • Banks report savings interest to the IRS on Form 1099-INT, and you must report the same amount on your tax return as ordinary income.
  • You owe tax on interest in the year it is credited to your account, regardless of whether you withdraw it or leave it to compound.
  • The tax rate on interest is your marginal income tax rate — the same rate that applies to your salary or other income — not a special lower rate.
  • Interest earned in a traditional IRA or 401(k) is not taxed until you withdraw it; interest in a Roth IRA grows tax-free if you follow withdrawal rules.
  • Some states do not tax interest income, while others tax it at the same rate as federal income; your state matters as much as your federal bracket.

How the 1099-INT form works and when you receive it

Your bank sends you a 1099-INT by January 31 of the year following the one in which you earned the interest. If you earned $10 or more in interest during 2024, the bank must issue the form. The form shows the total interest credited to your account across all accounts you hold at that bank.

You receive a copy for your records and a copy goes to the IRS. When you file your tax return, you report the amount from Box 1 of the 1099-INT on Schedule B (if you have other interest or dividend income) or directly on Form 1040 (if this is your only interest income). The IRS matches what you report against what the bank reported, so the numbers must align.

If you hold accounts at multiple banks, each will send its own 1099-INT. You add up all the interest from all the forms and report the total on your return. If you earned less than $10 at a particular bank, that bank may not issue a form, but you still owe tax on that interest — you report it even if you do not receive a 1099-INT.

Why high-yield accounts create a larger tax bill than traditional savings

A high-yield savings account currently pays 4% to 5% APY, while a traditional savings account at a large bank pays 0.01% to 0.05%. On a $10,000 balance, the difference is stark: a high-yield account earns roughly $400 to $500 per year, while a traditional account earns $1 to $5. That extra $395 to $499 is taxable income.

The tax on that interest is real money out of your pocket. If you are in the 24% federal bracket and your state taxes income at 5%, you pay roughly 29% of the interest in combined tax. On $500 in interest, that is about $145 in tax owed. Over five years, if you earn $2,500 in interest, you owe roughly $725 in tax.

This does not mean high-yield accounts are a bad choice — the interest still grows your money faster than a traditional account, even after tax. But it does mean the advertised rate is not the rate you keep. If a high-yield account pays 4.5% and you are in the 24% bracket, your after-tax return is closer to 3.4%.

Tax-advantaged accounts where savings interest grows without when ready tax

If you have access to a traditional IRA or 401(k), interest earned inside that account is not taxed in the year it is earned. The interest compounds tax-deferred, meaning you owe no federal tax until you withdraw the money in retirement. This can significantly accelerate growth over decades, because the money that would have gone to taxes stays in the account and earns interest on itself.

A Roth IRA works differently: you pay tax on the money before you put it in, but then all interest and growth is tax-free forever, including when you withdraw it in retirement. If you expect to be in a higher tax bracket later, a Roth can save you more money than a traditional account.

High-yield savings accounts held inside these retirement accounts follow the same tax rules as the account itself. A high-yield savings account inside a traditional IRA earns interest tax-deferred. A high-yield savings account inside a Roth IRA earns interest tax-free. However, these accounts have contribution limits and withdrawal rules, so they are not a replacement for a regular savings account — they serve a different purpose.

State and local taxes on savings interest

Federal income tax is only part of the picture. Most states also tax interest income at their own rates, which range from 0% to roughly 13% depending on the state. A few states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — do not tax interest income at all. If you live in one of these states, you owe only federal tax on your savings interest.

If you live in a state that does tax interest, the combined federal and state rate can be substantial. Someone in the 24% federal bracket living in California (which taxes interest at up to 13.3%) pays roughly 37% of their interest in combined tax. On $500 in interest, that is roughly $185.

Some cities and counties also levy local income tax on interest, though this is less common. If you live in a place with local income tax — such as New York City or certain Ohio municipalities — add that rate to your federal and state rates to find your true tax burden on savings interest.

Strategies to reduce the tax impact of high-yield savings

You cannot avoid tax on savings interest, but you can structure where you hold the money to minimize it. The most straightforward approach is to keep money you will need within the next few years in a regular high-yield savings account and accept the tax. The after-tax return still beats inflation and beats a traditional savings account.

If you have longer-term money — funds you will not touch for five or more years — consider whether a Roth IRA makes sense for you. You can contribute up to $7,000 per year (or $8,000 if you are 50 or older), and all growth is tax-free. This works best if you have earned income and are not already maxing out retirement contributions.

For very large balances, some people use a combination: keep three to six months of expenses in a high-yield savings account for emergencies, and move longer-term savings into a Roth IRA or other tax-advantaged account. This balances liquidity with tax efficiency. However, this strategy only works if you have the income to contribute and do not need the money before retirement.

What happens if you do not report savings interest on your tax return

The IRS receives a copy of every 1099-INT your bank sends. If you do not report the interest on your return, the IRS will eventually notice the discrepancy and send you a notice. You will owe the tax you should have paid, plus interest on that unpaid tax (currently around 8% per year), plus penalties that can range from 20% to 75% of the unpaid tax depending on the reason for the error.

If the IRS determines you intentionally did not report the interest, the penalties are steeper and can include criminal charges in extreme cases. If it was an honest mistake, the IRS is usually willing to work with you, but you still owe the tax and interest. It is far cheaper and simpler to report the interest when you file.

If you earned less than $10 at a bank and did not receive a 1099-INT, you still owe tax on that interest. Report it on your return even without the form. The amount is small enough that the IRS is unlikely to pursue it, but the law requires you to report all interest income.

Frequently Asked Questions

Do I have to report savings interest if I earned less than $600?

Yes. The $600 threshold applies only to certain types of income reported on newer forms like 1099-K. For interest income on a 1099-INT, you must report all interest, even $1, if you earned it. However, banks only issue a 1099-INT if you earned $10 or more, so small amounts may not generate a form — but you still owe tax on them.

Can I deduct the taxes I pay on savings interest from my taxable income?

No. Interest income is added to your taxable income; you cannot deduct the tax you owe on it. You can deduct investment expenses in some cases, but not the income tax itself. The tax is calculated after you report all your income.

What if I have a joint account with my spouse — how is the interest taxed?

The bank reports the total interest on the 1099-INT. You and your spouse must decide how to split it for tax purposes, usually based on each person's ownership stake in the account. If you own it equally, you each report half the interest. You should keep records of how you split it in case the IRS asks.

Does interest earned in a money market account get taxed the same way as a savings account?

Yes. Money market accounts are savings accounts, and interest earned in them is reported on a 1099-INT and taxed as ordinary income at your full tax rate, just like interest from a high-yield savings account.

If I move money between high-yield accounts, do I owe tax on the transfer?

No. Moving money from one account to another is not a taxable event. You only owe tax on the interest the money earns, not on the money itself. Each bank reports only the interest it paid you, so transferring between banks does not create extra tax.
