Yes, you owe income tax on savings account interest

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 must report it on your tax return, and you may owe federal income tax on it. Most banks will send you a Form 1099-INT in January showing how much interest you earned the previous year, and that figure goes on your tax return.

How much tax you actually owe depends on your total income and your tax bracket. Someone in the 12% federal tax bracket pays roughly 12 cents in federal tax for every dollar of interest earned. Someone in the 22% bracket pays roughly 22 cents per dollar. State and local income taxes may also explore, depending on where you live.

The bank does not withhold this tax automatically — you pay it when you file your return or through quarterly estimated tax payments if you have a large amount of interest income. This is different from a paycheck, where your employer withholds tax upfront.

Key Takeaways

  • Banks report savings interest to the IRS on Form 1099-INT, and you must include that amount as income on your tax return.
  • The tax you owe depends on your tax bracket; interest is taxed at your marginal rate, not a flat rate.
  • You do not have to report interest under $10 if the bank does not send you a Form 1099-INT, but you still owe tax on it.
  • High-yield savings accounts earn more interest than traditional savings accounts, which means higher tax bills unless the account is in a tax-advantaged structure.
  • State and local taxes may explore to savings interest in addition to federal tax, depending on your state.

When the bank sends you Form 1099-INT

Your bank will mail or email you a Form 1099-INT if you earned $10 or more in interest during the calendar year. This form shows the total interest paid to you and goes to both you and the IRS. You receive Copy B; the IRS receives Copy A.

The form arrives by January 31 of the following year. If you earned interest at multiple banks, you will receive a separate 1099-INT from each one. You must report the total from all forms on your tax return, whether you file Form 1040 (the main individual return) or another form depending on your situation.

If you earned less than $10 in interest, the bank may not send a 1099-INT. However, you still owe tax on that interest — you just have to track it yourself and report it on your return.

How your tax bracket determines what you pay

Savings interest is added to your other income and taxed at your marginal tax rate — the rate that applies to your highest dollar of income. If you earn $50,000 in wages and $500 in savings interest, that $500 is taxed at whatever bracket your $50,500 total falls into, not at a separate rate.

For 2024, federal tax brackets for single filers range from 10% on the first portion of income to 37% on income above $191,950. A married couple filing jointly faces different bracket thresholds. Your state may also tax interest income at rates ranging from 0% (in states with no income tax) to over 10% in high-tax states.

This means the same $1,000 in interest costs different people different amounts. Someone earning $30,000 total income might owe roughly $100 in federal tax on that interest; someone earning $200,000 might owe roughly $370.

Tax-advantaged accounts that shield savings interest

If you want to earn interest without paying tax on it when ready, certain account types defer or eliminate the tax:

  • Individual Retirement Accounts (IRAs) — Interest earned in a traditional IRA or Roth IRA is not taxed while it sits in the account. With a Roth IRA, you never pay tax on the interest when you withdraw it in retirement (if you follow the rules). With a traditional IRA, you pay tax when you withdraw the money.
  • Certificates of Deposit (CDs) in an IRA — A CD held inside an IRA gets the same tax deferral as other IRA investments.
  • Health Savings Accounts (HSAs) — If you have a may have access to high-deductible health plan, interest in an HSA is not taxed as long as you use withdrawals for medical expenses.
  • 529 college savings plans — Interest earned in a 529 plan is not taxed if you use the money for may have access to education expenses.

These accounts have contribution limits, withdrawal rules, and may be able to access requirements. A regular savings account outside these structures offers no tax shelter — all interest is taxable.

What happens if you do not report savings interest

The IRS receives a copy of every Form 1099-INT your bank sends. If you do not report that interest on your tax return, the IRS will likely notice the mismatch between what the bank reported and what you reported (or did not report). This can trigger an audit notice or a bill for back taxes plus penalties and interest.

The penalty for underreporting income is typically 20% of the underpaid tax, plus interest that accrues from the original due date. If the IRS determines the underreporting was intentional, the penalty can reach 75%. Even if it was an honest mistake, you will owe the tax plus interest.

Reporting the interest takes minutes — you straightforward add the amount from your 1099-INT to your other income on your tax return. It is far cheaper and simpler than dealing with an audit later.

How high-yield savings accounts change your tax picture

High-yield savings accounts currently pay 4% to 5% annual interest, compared to 0.01% or less at traditional banks. This means a $10,000 balance earns $400 to $500 per year instead of $1. The higher interest is attractive, but it also means a higher tax bill.

If you are in the 24% federal tax bracket and earn $500 in interest, you owe roughly $120 in federal tax on it (plus any state tax). The after-tax return is closer to 3% or 3.5%, not the advertised 4% or 5%. This is still better than a traditional savings account, but it is worth factoring into your decision about where to keep your money.

The tax impact is one reason some people keep emergency funds in a high-yield account (for the interest) but move longer-term savings into an IRA or other tax-advantaged account (to avoid annual tax on the interest).

State and local taxes on savings interest

In addition to federal income tax, most states tax savings interest at their ordinary income tax rate. Nine states have no income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes interest and dividends but not wages). In these states, you owe only federal tax on savings interest.

In other states, the tax rate ranges from roughly 1% to over 13%, depending on the state and your income level. New York, California, and New Jersey are among the higher-tax states. Your state tax bill on $500 in interest could be anywhere from $0 (in a no-income-tax state) to $65 or more (in a high-tax state with a high bracket).

Some states offer tax breaks for interest earned in certain accounts or for certain types of savers (such as seniors), but these are uncommon. Check your state's tax authority website or speak with a tax preparer if you want to know your state's specific rules.

Frequently Asked Questions

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

Yes. The $10 threshold only determines whether the bank sends you a Form 1099-INT. You still owe tax on any interest you earned, even if it is $1. You must track it yourself and report it on your return.

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

No. You report the gross interest the bank paid you. Account fees are not deductible against interest income on your personal tax return. You pay tax on the full amount the bank reports on the 1099-INT.

What if I moved money between banks mid-year and earned interest at two places?

You will receive a separate 1099-INT from each bank showing the interest each one paid. Add all the amounts together and report the total on your tax return. The IRS will receive copies from both banks, so they will expect to see the combined total.

Is interest from a joint savings account taxed differently?

The interest is taxed to whoever owns the account or, if both people own it jointly, it may be split between you. The bank will issue the 1099-INT in the name of the account owner or primary account holder. If you own it jointly and want to split the tax liability, you may need to file amended returns or work with a tax preparer to allocate it correctly.

Do I owe tax on interest if I have not withdrawn it yet?

Yes. You owe tax on interest in the year it is earned and credited to your account, even if you leave it sitting there and do not withdraw it. The IRS taxes interest on an accrual basis, not when you actually use the money.
