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 you earn $500 in interest over a year, that $500 gets added to your wages, self-employment income, and any other money you made, and you owe federal income tax on the total. Most banks send you a Form 1099-INT in January showing how much interest you earned the previous year, and you report that number on your tax return.
The tax you owe depends on your overall income and which tax bracket you fall into. Someone earning $30,000 a year pays a lower rate on that interest than someone earning $150,000. State income tax also applies in most states — your state taxes the interest at whatever rate it uses for regular income. A few states (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming) have no state income tax at all, so residents there owe only federal tax on interest.
The bank does not withhold tax from the interest before it hits your account. The money goes in full, and you handle the tax bill when you file your return or make quarterly estimated payments if you owe a large amount.
Key Takeaways
- Savings account interest is taxed as ordinary income at your federal tax rate, plus your state rate if your state has income tax.
- Your bank reports the interest on Form 1099-INT, which you receive by January 31 and must report on your tax return.
- The amount of tax you owe depends on your total income for the year and which tax bracket that puts you in.
- You do not pay tax on the interest until you file your return — the bank does not withhold it automatically.
- Interest under $10 may not generate a Form 1099-INT, but you still owe tax on it if you have other income.
When you receive the Form 1099-INT and what it shows
Banks mail Form 1099-INT by January 31 each year for any account that earned $10 or more in interest during the previous calendar year. The form shows the account holder's name, Social Security number, the bank's name and tax ID, and the total interest paid. If you had multiple savings accounts at the same bank, the interest from all of them gets combined on one form. If you banked at different institutions, each one sends its own 1099-INT.
You receive a copy in the mail and the IRS receives a copy electronically. When you file your federal return, you report the interest amount from Box 1 of the 1099-INT on Schedule B (Interest and Ordinary Dividends) if you have more than $1,500 in total interest and dividends, or directly on Form 1040 if you have less. Your state tax return may have its own line for interest income, or it may follow the federal number.
If you earned less than $10 in interest, the bank does not send a 1099-INT, but you still owe tax on that money if you have other income. Keep your own records of small interest amounts and report them on your return.
How your tax bracket determines what you actually pay
The federal tax rate on interest is not a flat percentage — it depends on your total income for the year. The IRS uses tax brackets, which are income ranges with different rates. For 2024, a single person with $30,000 in total income falls into the 12% bracket, meaning the last dollars of income (including interest) are taxed at 12%. Someone with $100,000 in income is in the 24% bracket.
This means $500 in interest does not cost the same person the same amount of tax. A person in the 12% bracket pays roughly $60 in federal tax on $500 of interest. A person in the 24% bracket pays roughly $120 on the same $500. State tax stacks on top — if your state has a 5% income tax, you owe an additional $25 on that $500.
Tax brackets change each year, and the IRS publishes new ones in late 2023 for the 2024 tax year. If you want to estimate what you will owe before filing, multiply your interest by your federal bracket rate, then add your state rate. The IRS website and most tax software show current brackets.
Interest from high-yield savings accounts and money market accounts
High-yield savings accounts and money market accounts pay more interest than traditional savings accounts — sometimes 4% to 5% annually instead of 0.01%. That higher interest is also fully taxable at your ordinary income rate. A $10,000 balance in a high-yield account earning 4.5% generates $450 in interest per year, all of which is taxable income.
The bank still sends a 1099-INT for the interest, and you report it the same way as interest from any other savings account. The only difference is the dollar amount. Some people use high-yield accounts specifically because the interest helps offset inflation, but they factor in the tax cost when deciding whether the rate is worth it.
If you have multiple high-yield accounts at different banks, each bank sends its own 1099-INT. Add all the interest amounts together when you file your return.
What happens if you do not report the interest
The IRS receives a copy of every 1099-INT that your bank sends. If you do not report the interest on your return, the IRS computer system flags the discrepancy and can send you a notice asking for the missing income and the tax owed, plus penalties and interest on the unpaid amount. The penalty for not reporting income is usually 20% of the underpaid tax, and interest accrues daily until you pay.
If the interest amount is small — say, $50 — the IRS may not pursue it aggressively, but it is still technically a violation. The safest approach is to report all interest, even small amounts. If you lost your 1099-INT or never received it, contact the bank and ask for a duplicate, or call the IRS at 800-829-1040 and they can help you track it down.
Strategies to reduce interest income tax
You cannot avoid tax on savings interest entirely if you earn it, but you can reduce how much interest you earn in the first place. Some people keep emergency funds in a regular savings account earning almost nothing rather than a high-yield account, to keep taxable income lower. This is usually not a smart trade-off — the tax on extra interest is almost always less than the interest itself.
A more practical approach is to use tax-advantaged accounts for savings that you want to grow without annual tax bills. Roth IRAs and Roth 401(k)s let you earn interest and investment gains tax-free, as long as you follow withdrawal rules. Traditional IRAs and 401(k)s defer the tax until you withdraw the money in retirement. Certificates of Deposit (CDs) in regular savings accounts are also taxed annually on interest, so moving money to a Roth IRA CD can eliminate that tax.
If you are retired and living on a fixed income, you may also be able to use a Series I Savings Bond (issued by the U.S. Treasury), which earns interest that you can defer reporting until you cash it in, potentially years later. These bonds have purchase limits and other rules, so check the Treasury website before buying.
State income tax on savings interest
Most states tax savings interest at the same rate they tax wages and other income. A few states treat interest differently — for example, some states exempt interest income for people over 59½, or cap the tax on retirement account interest. Check your state's tax authority website to see if any exemptions apply to you.
If you live in a state with no income tax and move to one that does, or vice versa, the tax treatment of your interest changes. Interest earned while you lived in the no-tax state is not taxed retroactively by the new state, but interest earned after you move is taxable in your new state. Keep records of when you moved and which state you were in when the interest was paid.
Frequently Asked Questions
Do I have to report interest if I earned less than $10?
The bank does not send a 1099-INT for interest under $10, but you still owe tax on it if you have other income. Report it on your return using your own records. If interest is your only income and it is under $10, you may not be required to file a return at all, depending on your age and filing status.
What if I earned interest in a joint account?
The bank reports the full interest amount on a 1099-INT in the name and Social Security number of the first account holder listed. You and the other owner need to decide how to split the income for tax purposes — usually 50/50, but it can be different if you contributed unequally. Report your share on your return and keep documentation of the split in case the IRS asks.
Can I deduct savings account fees from the interest income?
No. Interest is reported as gross income, and account fees are not deductible against it. If your bank charges a monthly fee that exceeds the interest you earn, you still owe tax on the interest and lose money overall. This is one reason to shop for accounts with no fees.
Do I owe tax on interest if I am a dependent?
Yes, you owe tax on interest income even if someone else claims you as a dependent on their return. Your parent or guardian does not report your interest on their return — you report it on yours. You may still be required to file your own return depending on the amount of interest and other income you earned.
What if the bank made an error on the 1099-INT?
Contact the bank immediately and ask them to issue a corrected 1099-INT (marked as a correction). They will send the corrected form to you and the IRS. If you already filed your return with the wrong amount, file an amended return (Form 1040-X) once you receive the corrected 1099-INT.
