Savings account interest counts as taxable income

The interest your bank pays you on a savings account is ordinary income to the IRS, taxed at your regular income tax rate. If your savings account earned $50 in interest last year, that $50 gets added to your other income — wages, self-employment earnings, investment gains — and taxed accordingly. You do not get a separate, lower rate for interest the way you might for long-term stock gains.

Your bank reports this interest to both you and the IRS on a Form 1099-INT each January. The threshold for receiving the form is low: most banks send one if you earned $10 or more in interest during the year, though some send them at $1. Even if you do not receive a 1099-INT, you still owe tax on the interest if you earned it.

The tax you owe depends on your total income and your tax bracket. Someone in the 12 percent federal bracket pays 12 cents on each dollar of interest. Someone in the 22 percent bracket pays 22 cents. State income tax, where it exists, stacks on top of that.

Key Takeaways

  • Savings account interest is taxed as ordinary income at your regular tax rate, not at a special lower rate.
  • Your bank sends you a Form 1099-INT in January reporting interest of $10 or more, and the IRS gets a copy too.
  • You report the interest on your tax return even if you do not receive a 1099-INT, and even if the amount is small.
  • High-yield savings accounts pay more interest, which means more tax owed, but the after-tax return is usually still better than traditional savings accounts.

How the IRS finds out about your interest

Banks are required to report interest to the IRS using Form 1099-INT. They send you a copy (usually by January 31) and file a copy with the IRS under your Social Security number. The IRS then matches what you report on your tax return against what the bank reported. If you do not report the interest, the IRS will notice the mismatch.

This matching system is automated and catches most unreported interest. The penalty for not reporting is typically 20 percent of the unpaid tax, plus interest on the unpaid amount, compounding daily. It is far cheaper to report the interest than to ignore it and hope the IRS does not notice.

If you have multiple savings accounts at different banks, each bank sends its own 1099-INT. You add up all the interest from all the forms and report the total on your tax return.

Where to report interest on your tax return

If you file Form 1040 (the main individual income tax form), you report savings account interest on Schedule 1, Part I, line 8a. The line is labeled "Interest." You write in the total interest from all your 1099-INT forms.

If your total interest income is $1,500 or less and you have no other investment income, you can report it directly on Form 1040 without filing Schedule 1. But if you use tax software, it usually handles this automatically — you enter the 1099-INT information and the software puts it in the right place.

If you are married and file jointly, you combine your interest with your spouse's interest and report the combined total. Each person's 1099-INT goes to the IRS separately, but you report one combined number on your joint return.

When interest is too small to report

There is no dollar threshold below which interest becomes tax-free. Even $1 of interest is technically taxable income. However, if your total income is low enough that you do not owe tax anyway, reporting the interest does not create a tax bill — it just increases your reported income without pushing you into a tax bracket where you owe anything.

The practical threshold is whether you are required to file a tax return at all. For 2024, a single person under 65 with no dependents does not have to file if their income is below $14,600. If your only income is $200 in savings account interest, you do not have to file. But if you have wages or other income that puts you over the threshold, you must report the interest too.

If you do not file a return but the bank reported your interest to the IRS, the IRS may send you a notice asking why you did not file. It is simpler to file and report the interest than to explain why you did not.

High-yield savings accounts and the tax trade-off

A high-yield savings account might pay 4 to 5 percent annual interest, compared to 0.01 percent at a traditional bank. On $10,000, that is $400 to $500 per year instead of $1. The tax on that extra $400 is real — if you are in the 22 percent bracket, you owe $88 in federal tax on the extra interest. But you still come out ahead: you keep $312 more than you would have at a traditional account.

The tax does not erase the benefit of a higher rate. It just means the after-tax return is lower than the advertised rate. If a high-yield account pays 4.5 percent and you are in the 24 percent bracket, your after-tax return is roughly 3.4 percent. That is still much better than the 0.01 percent after-tax return at a traditional bank.

Some people move money to high-yield accounts in December to capture a few months of interest, then move it back. The interest is still taxable in the year you earned it, regardless of when you move the money. This strategy does not reduce your tax bill.

Tax-advantaged alternatives to regular savings accounts

If you want to save money without paying tax on the interest each year, a Roth IRA or Roth 401(k) lets you earn interest tax-free, as long as you follow the withdrawal rules. Money in a Roth grows without any annual tax bill. When you withdraw it in retirement, the interest comes out tax-free.

A traditional IRA or 401(k) defers the tax: you do not pay tax on the interest while the money is in the account, but you pay tax on withdrawals in retirement. This is useful if you expect to be in a lower tax bracket later.

A 529 college savings plan also grows tax-free if the money is used for education. Interest in a 529 is not taxed as long as you withdraw it for tuition, room and board, or other may have access to education expenses.

These accounts have contribution limits and withdrawal rules. A regular savings account has no limits and no restrictions, which is why most people use them for emergency funds or short-term goals. The tax on the interest is the trade-off for that flexibility.

What happens if you do not receive a 1099-INT

If you earned interest but your bank did not send you a 1099-INT, you still owe tax on it. Banks are only required to send a 1099-INT if interest reaches $10 or more, but some banks have lower thresholds. If you earned $5 in interest and received no form, you still report it on your tax return.

You can find your interest income by logging into your bank account online or calling the bank. Most banks show year-to-date interest earned in the account summary. If you cannot find it, ask the bank directly — they have a record of every cent paid to your account.

If you report interest that the IRS did not receive a 1099-INT for, there is no problem. The IRS knows that not all interest is reported on 1099-INT forms. What matters is that your return matches the total interest you actually earned.

Frequently Asked Questions

Do I have to pay state income tax on savings account interest?

Yes, in states with income tax. The interest is added to your state taxable income and taxed at your state rate. Seven states (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, and Wyoming) have no income tax, so residents of those states pay only federal tax on interest. Other states tax it like any other income.

What if I earned interest in a joint account with my spouse?

The bank reports the interest to the IRS under one Social Security number, usually the primary account holder's. You and your spouse should decide who reports it on the tax return — typically whoever the 1099-INT is issued to. If you file jointly, it does not matter which of you reports it, as long as the total is reported once.

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

No. Interest income is taxable, but the tax you pay on it is not deductible. You cannot reduce your taxable income by the amount of tax you owed on the interest. The interest itself is the taxable amount; the tax is what you owe on that amount.

Does a CD earn interest that gets taxed the same way?

Yes. A certificate of deposit (CD) pays interest that is taxed as ordinary income, reported on a 1099-INT just like savings account interest. The bank reports it in the year you earn it, even if you do not withdraw the CD until later. Some CDs allow you to defer withdrawals, but the interest is still taxable in the year it accrues.

What if my savings account interest pushes me into a higher tax bracket?

It can, but only if your total income is close to a bracket boundary. If you earn $50,000 in wages and $2,000 in interest, your total taxable income is $52,000. If that $2,000 pushes you from the 12 percent bracket into the 22 percent bracket, you pay 22 percent on the portion of income above the bracket threshold, not on all $2,000. The tax system is progressive — you do not pay a higher rate on all your income, only on the portion above the threshold.
