Yes, you pay federal income tax on high yield savings interest, and possibly state tax too

Interest earned in a high yield savings account is taxable income. The bank reports it to the IRS on a Form 1099-INT, and you report it on your tax return. The interest counts as ordinary income, which means it is taxed at your regular income tax rate — not at a lower capital gains rate. There is no threshold: even $1 in interest is taxable, though you only have to report it if your total interest income exceeds $10 (the IRS reporting threshold for 2024, though this may change year to year).

The tax is due on the interest you earned during the calendar year, regardless of whether you withdraw the money. If you earn $500 in interest between January and December, you owe tax on that $500 even if it stays in the account. You pay the tax when you file your annual return, usually by April 15 of the following year.

State income tax applies the same way in most states. If your state has an income tax, you report the same interest income on your state return. A handful of states — including Pennsylvania, Illinois, and Mississippi — do not tax interest income at all, so residents of those states owe federal tax but not state tax. A few others tax interest only if it exceeds a certain amount (usually $1,200 or more per year). Check your state's tax authority website to confirm your state's rules.

Key Takeaways

  • High yield savings interest is taxed as ordinary income at your federal tax rate, and you report it on Form 1099-INT when you file your return.
  • State income tax on savings interest varies: some states do not tax it at all, while others tax it the same way the federal government does.
  • The bank automatically withholds no tax from savings interest, so you may owe money when you file unless you adjust your withholding elsewhere.
  • Interest earned in tax-advantaged accounts like IRAs or 529 plans is not taxed in the year it is earned, though withdrawal rules differ by account type.

The bank does not withhold tax from savings interest

Unlike a paycheck, where your employer withholds federal and state income tax before you receive the money, a bank does not withhold tax from savings interest. The full amount of interest is deposited into your account, and you are responsible for setting aside money to pay the tax when you file your return.

This matters if you earn enough interest that it pushes you into a higher tax bracket or if you have other income sources. For example, if you earn $50,000 in wages and $3,000 in savings interest, your taxable income is $53,000, and you pay tax on the full amount. If you did not plan for that extra $3,000 in tax liability, you may owe money in April.

One way to handle this is to increase the tax withholding on your paycheck (if you have one) using Form W-4. Another is to make estimated tax payments to the IRS quarterly if you have substantial non-wage income. A tax professional can help you figure out which approach makes sense for your situation.

How much tax you owe depends on your total income and tax bracket

The tax rate on savings interest is your marginal tax rate — the rate you pay on your last dollar of income. For 2024, federal tax brackets range from 10% to 37%, depending on your filing status and total income. If you are in the 22% bracket, you pay 22% federal tax on your interest income. If you are in the 12% bracket, you pay 12%.

Your state tax rate, if applicable, stacks on top of the federal rate. So if you live in a state with a 5% income tax and you are in the 22% federal bracket, you pay 27% total tax on your interest. A $1,000 in interest would cost you $270 in combined federal and state tax.

The higher your total income, the higher your tax bracket, and the more tax you owe on the same amount of interest. This is why a high yield savings account earning 4% interest may not feel as attractive when you factor in taxes: if you are in the 24% federal bracket plus state tax, your after-tax return might be closer to 2.5% or 3%.

Tax-advantaged accounts let you defer or avoid tax on interest

If you want to earn interest without paying tax on it immediately, you can use a traditional IRA or Roth IRA. Both allow you to hold a high yield savings account or money market fund inside the IRA, and the interest is not taxed in the year it is earned.

In a traditional IRA, you pay tax on the interest when you withdraw the money in retirement. In a Roth IRA, you never pay tax on the interest — withdrawals in retirement are tax-free, as long as you follow the rules (you must be 59½ and have held the account for at least five years). The tradeoff is that IRAs have annual contribution limits ($7,000 for 2024 if you are under 50, $8,000 if you are 50 or older) and withdrawal restrictions before retirement.

A 529 college savings plan also lets interest grow tax-free, as long as you use the money for may have access to education expenses. If you withdraw money for non-education purposes, you pay tax on the earnings plus a 10% penalty.

For most people, a regular high yield savings account is still the right choice for emergency funds or short-term savings, because you need access to the money without penalties. But if you have money you will not need for years and you have already maxed out your IRA contributions, a 529 or taxable account may be worth considering.

Form 1099-INT tells you what the bank reported to the IRS

Your bank sends you a Form 1099-INT by January 31 each year, showing the total interest you earned during the previous calendar year. This is the same form the bank sends to the IRS. You use the amount on the 1099-INT to fill out your tax return.

Check the 1099-INT against your own records. If you had multiple savings accounts at the same bank, the interest may be combined on one form. If you had accounts at different banks, you will receive a separate 1099-INT from each one. Make sure the total matches what you expect. If there is an error, contact the bank and ask for a corrected form (a Form 1099-INT with a "corrected" box checked).

If you earned less than $10 in interest during the year, the bank may not be required to send you a 1099-INT, but you still owe tax on that interest if your total interest income from all sources exceeds $10. Keep your own records in case the IRS asks.

Interest earned before you close an account is still taxable

If you close a high yield savings account partway through the year, you still owe tax on all the interest earned up to the closing date. The bank will report that interest on the 1099-INT for that year. You cannot avoid the tax by moving the money to a different bank or account type.

Similarly, if you transfer money from a high yield savings account to a regular savings account or checking account, the interest you earned in the high yield account is still taxable. Moving the money does not change the tax treatment.

The only way to avoid tax on interest is to not earn it (by keeping money in a non-interest-bearing account), to earn it in a tax-advantaged account (like an IRA), or to offset it with losses or deductions — which is rarely practical for savings interest.

Frequently Asked Questions

Do I have to report savings interest if I earned less than $10?

The bank does not have to send you a 1099-INT if you earned less than $10, but you still owe tax on it. If your total interest income from all sources is $10 or more, you must report all of it, including amounts under $10 from individual accounts. Keep your own records.

What if the 1099-INT amount is wrong?

Contact your bank immediately and ask for a corrected Form 1099-INT. The bank will send the corrected version to you and the IRS. Do not file your tax return until you have the correct form. If you already filed and the amount was wrong, you may need to file an amended return.

Can I deduct savings interest as a loss?

No. Savings interest is income, not a loss. You cannot deduct it. The only deductions related to savings are things like investment advisory fees (and only if you itemize deductions, which most people do not), but ordinary savings interest has no deduction.

Is interest from a money market account taxed the same way?

Yes. Money market accounts, high yield savings accounts, and regular savings accounts are all taxed the same way. The interest is ordinary income, reported on Form 1099-INT, and taxed at your marginal rate. The only difference is the interest rate the bank pays you.

What happens if I do not report the interest on my tax return?

The IRS receives a copy of the 1099-INT from your bank. If you do not report the interest, the IRS will likely catch it and send you a bill for the unpaid tax plus penalties and interest. It is much easier and cheaper to report it correctly the first time.
