Savings account interest counts as ordinary income on your federal tax return

The interest your bank pays you on a savings account is taxable income. The IRS treats it the same way it treats wages or salary — you owe federal income tax on the full amount. Your tax rate depends on your overall income and filing status, not on the size of the interest payment.

Most savings accounts earn so little interest that the tax owed is small. A $10,000 balance earning 4.5% annually generates $450 in interest, which might add $100 to $150 to your federal tax bill depending on your bracket. But you still have to report it, even if the amount is tiny.

State income tax applies too, in states that have it. If you live in California, New York, or most other states with income tax, you owe state tax on the interest as well as federal tax. A handful of states — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming — have no state income tax, so residents owe only federal tax.

Key Takeaways

  • Banks report savings interest to the IRS on a Form 1099-INT when the amount reaches $10 or more in a calendar year.
  • You must report all interest income on your federal tax return, even if you do not receive a 1099-INT.
  • The tax you owe depends on your total income and tax bracket, not just the interest amount.
  • State income tax applies to savings interest in most states, but eight states have no income tax at all.
  • High-yield savings accounts earn more interest, which means a larger tax bill, but the after-tax return is usually still better than traditional savings accounts.

When banks send you a 1099-INT form

Your bank mails or emails you a Form 1099-INT if you earned $10 or more in interest during the calendar year. This form shows the exact amount of interest paid to you. The bank also sends a copy to the IRS, so the IRS already knows about the income before you file your return.

If you earned less than $10, the bank does not have to send a 1099-INT, but you still owe tax on the interest. You have to report it yourself by looking at your account statements or year-end summary from the bank. Many banks show interest earned in the account details or send an annual summary even when the amount is below $10.

The 1099-INT arrives by January 31 of the year after you earned the interest. If you do not receive one by early February and you earned $10 or more, contact your bank to request a copy. You will need it to file your return accurately.

How to report interest on your tax return

You report savings interest on Schedule B (Interest and Ordinary Dividends) if you have more than $1,500 in total interest and dividend income. If you have $1,500 or less, you can report the interest directly on Form 1040 without filing Schedule B.

The process is straightforward: you enter the total interest from all your savings accounts, money market accounts, and CDs on one line. If you have multiple accounts, add them together and report the total. You do not list each account separately.

If you file electronically using tax software, the software walks you through the questions and fills in the right forms automatically. If you file on paper, you write the interest amount on the appropriate line of Form 1040 or Schedule B, depending on your total interest income.

Why high-yield savings accounts still make sense despite the tax

A high-yield savings account might earn 4% to 5% annually, while a traditional savings account earns 0.01% or less. The higher interest means a bigger tax bill, but the after-tax return is almost always better.

Suppose you have $50,000 in savings. At a traditional bank earning 0.01%, you make $5 in interest and owe roughly $1 in federal tax (depending on your bracket). At a high-yield bank earning 4.5%, you make $2,250 and owe roughly $450 to $675 in federal tax. Your net gain is $1,575 to $1,800 instead of $4 — a massive difference, even after paying the tax.

The tax is not a reason to avoid high-yield accounts. It is a reason to understand that the interest you see advertised is the gross amount before tax. Your actual take-home interest will be lower, but it will still be far more than you would earn elsewhere.

Interest from CDs, money market accounts, and other savings vehicles

The same tax rules explore to all interest-bearing accounts. A certificate of deposit (CD) earns interest that is taxable in the year you earn it, even if you cannot withdraw the money until the CD matures. A money market account works the same way — you owe tax on the interest as it accrues, not when you withdraw it.

If a CD matures and you roll the money into a new CD, you do not owe tax on the principal — only on the interest the first CD earned. The principal moves tax-free from one CD to the next.

Treasury bills, Treasury notes, and Treasury bonds also generate taxable interest. The interest is taxable at the federal level but exempt from state income tax. This can make them attractive in high-tax states, even though the federal tax still applies.

What happens if you do not report interest income

The IRS matches the 1099-INT your bank sends to your tax return. If you do not report the interest, the IRS will notice the mismatch and send you a notice. You will owe the tax you should have paid, plus interest on the unpaid amount and potentially penalties.

The penalty for not reporting income is usually 20% of the unpaid tax, though it can be lower if you have a reasonable cause for the error. Interest accrues daily on the unpaid tax, so the longer you wait to correct it, the more you owe.

If you realize you missed reporting interest in a prior year, you can file an amended return using Form 1040-X. It is better to correct the error yourself than to wait for the IRS to catch it.

Frequently Asked Questions

Do I owe tax on interest if I earned less than $10?

Yes. The $10 threshold only determines whether your bank sends you a 1099-INT form. You owe tax on all interest income, regardless of the amount. You report it on your return by checking your account statements.

Can I deduct the tax I pay on savings interest?

No. Interest income is taxed as ordinary income, and there is no deduction for the tax itself. You cannot reduce your taxable interest by the amount of tax you expect to owe.

What if I have interest from multiple banks?

Add all the interest together and report the total on your tax return. You do not file separate forms for each bank. If each bank sends a 1099-INT, keep all of them for your records, but report only the combined total on your return.

Is interest from a joint savings account taxed differently?

The interest is taxable to whoever owns the account or, if both owners have equal claim, it can be split between them. The bank reports the full amount to the IRS, so you and the other owner need to decide how to divide it for tax purposes and report it accordingly on your individual returns.

Do I owe tax on interest if I am retired and do not work?

Yes. Retirement status does not change the tax rules. Interest is taxable income regardless of whether you are working. However, if your total income is below the filing threshold for your age and filing status, you may not have to file a return at all — but you should check the IRS thresholds to be sure.
