The tax you owe depends on how much interest your account earns, not on the account balance itself

The IRS taxes the interest your savings account earns, not the money you deposit. If your account earns $50 in interest over a year, that $50 is taxable income. The original deposit stays yours tax-free. The interest rate, the account type, and how long you hold the money determine how much interest accumulates—and therefore how much you owe in tax.

Your bank reports this interest to the IRS on a 1099-INT form if you earn $10 or more in a calendar year. You then report that same amount on your tax return as ordinary income, taxed at your regular income tax rate. There is no separate "savings account tax"—it works like wages or other income.

Key Takeaways

  • Interest earned in a savings account is taxed as ordinary income at your regular tax rate, whether that is 10%, 22%, 24%, or higher depending on your income bracket.
  • Your bank sends you a 1099-INT form if you earn $10 or more in interest during the year, and you report that amount on your tax return.
  • High-yield savings accounts earn more interest than traditional savings accounts, which means more tax owed, but the after-tax return is often still higher.
  • Money market accounts and certificates of deposit follow the same tax rule as regular savings accounts—only the interest is taxed, not your principal.
  • If you earn less than $10 in interest, your bank may not send a 1099-INT, but you still owe tax on that interest if you file a return.

How your tax bracket affects what you pay on savings interest

The amount of tax you owe on savings interest depends on your tax bracket—the percentage rate applied to your total income. If you are in the 22% bracket, you pay 22 cents in federal tax on every dollar of interest earned. If you are in the 12% bracket, you pay 12 cents per dollar. The higher your other income, the higher your bracket, and the more tax you owe on the same amount of interest.

This matters because a high-yield savings account earning 4.5% interest looks less attractive once you factor in tax. If you earn $450 in interest and are in the 24% bracket, you owe $108 in federal tax on that interest. Your after-tax gain is $342. State income tax, if your state has it, reduces that further. Some states tax savings interest; others do not.

The tax is due when you file your annual return, usually in April. You do not pay it when the interest hits your account. This means the full interest amount stays in your account and can earn more interest the following year—a small benefit of the delay.

When your bank sends you a 1099-INT and what to do with it

If you earn $10 or more in interest during a calendar year, your bank mails you a 1099-INT form by January 31 of the following year. This form shows the interest amount in Box 1. You receive a copy; the IRS receives a copy. When you file your tax return, you report this same amount on Schedule B (if you have other interest or dividend income) or directly on Form 1040 (if this is your only interest income).

The bank is required to send the form whether or not you actually owe tax—for example, if you are a dependent or have very low income. If you earn less than $10, your bank may not send a 1099-INT, but you still owe tax on that interest if you file a return. Keep your own records of interest earned in case you need to report it.

If you receive a 1099-INT and the amount is wrong, contact your bank when ready. They can issue a corrected form (a 1099-INT marked "CORRECTED") before the filing important date. If you file your return before receiving the form, you can file an amended return once you have the correct figure.

High-yield savings accounts and the tax trade-off

A high-yield savings account might earn 4% to 5% annually, while a traditional savings account earns 0.01% to 0.05%. The higher rate means more interest—and more tax. But even after tax, the high-yield account usually comes out ahead.

Suppose you have $10,000 in a high-yield account earning 4.5% and you are in the 24% tax bracket. You earn $450 in interest, owe $108 in tax, and keep $342. In a traditional account earning 0.02%, you earn $2 in interest, owe less than $1 in tax, and keep roughly $1.50. The high-yield account nets you $340 more, even after tax.

The trade-off shifts if interest rates fall or your tax bracket rises. If rates drop to 2% and you move into the 32% bracket, the math changes. But for most savers, the higher interest rate outweighs the higher tax bill.

Tax-advantaged accounts that avoid or defer this tax

Some accounts let you earn interest without paying tax on it when ready. A traditional IRA or 401(k) holds savings that earn interest tax-free while the money stays in the account. You pay tax only when you withdraw the money in retirement. A Roth IRA goes further: interest earned is never taxed, even in retirement, as long as you follow the withdrawal rules.

A 529 college savings plan works similarly—interest grows tax-free if you use the money for education. A health savings account (HSA) offers tax-free interest if you use withdrawals for medical expenses. These accounts have contribution limits and withdrawal rules, so they are not a fit for all savings goals, but they eliminate the annual tax on interest.

If you are saving for a goal that fits one of these account types, the tax savings can be substantial over time. A regular savings account earning $500 per year in a 24% bracket costs you $120 in tax. The same $500 in a Roth IRA costs you nothing.

Money market accounts and CDs follow the same tax rule

A money market account and a certificate of deposit (CD) earn interest just like a savings account, and that interest is taxed the same way. The bank sends a 1099-INT if you earn $10 or more, and you report it as ordinary income on your tax return. The interest rate is usually higher than a savings account, which means more interest earned and more tax owed.

CDs have one tax quirk: if you withdraw money before the maturity date, you pay an early withdrawal penalty. That penalty is not tax-deductible, so you lose money twice—once to the penalty and once to the tax on the interest you did earn. This is one reason to match the CD term to when you actually need the money.

State income tax on savings interest

Federal tax is only part of the picture. Some states tax savings interest; others do not. States with no income tax—including Texas, Florida, Tennessee, and Wyoming—do not tax savings interest. States with income tax usually tax it at the same rate they tax wages.

A few states offer limited breaks. Illinois does not tax interest income. Iowa does not tax interest from savings accounts held for more than a year. Most states tax all interest the same way, regardless of the account type or how long you hold the money.

If you live in a high-tax state and earn significant interest, moving money to a high-yield account in a no-tax state does not help—your state taxes interest based on where you live, not where the account is held. But if you are considering a move or have flexibility on where to keep savings, state tax is worth factoring into the decision.

Frequently Asked Questions

Do I owe tax on savings interest if I do not receive a 1099-INT?

Yes. If you earn less than $10 in interest, your bank may not send a 1099-INT, but you still owe tax on that interest if you file a return. Keep your own records of interest earned and report it on your tax return.

Can I deduct savings account fees from the interest I report?

No. You report the full interest amount on your tax return. Savings account fees are not deductible. However, if your bank pays you interest and also charges you a fee, the net amount is what you actually receive—the fee reduces your after-tax gain, but does not reduce your taxable interest.

What if I move money between savings accounts during the year?

The interest is taxed regardless of how many times you move the money. Each bank reports the interest earned in their account on a separate 1099-INT. You add up all the 1099-INT forms you receive and report the total interest on your tax return.

Is interest from a joint savings account taxed differently?

The interest is taxed to whoever owns the account or, if it is truly joint, it may be split between owners. Check with your bank on how they report interest from joint accounts. The IRS expects the person whose Social Security number is on the account to report the interest, unless you have a written agreement stating otherwise.

Do I owe tax on interest if I am a dependent?

Yes. Even if someone else claims you as a dependent, you owe tax on interest you earn. Your bank still sends a 1099-INT, and you still report it. Being a dependent does not exempt you from tax on interest income, though you may not owe federal tax if your total income is below the filing threshold for dependents.
