The IRS taxes your savings interest as ordinary income, at whatever rate matches your tax bracket
Interest earned in a high yield savings account is taxed as ordinary income by the federal government. This means the interest rate on your account does not matter — what matters is how much interest you actually earned, and what your total income was that year. A person in the 24% tax bracket pays federal tax on their savings interest at 24%. A person in the 12% bracket pays 12%. The bank does not withhold this tax automatically; you report it when you file your return.
Most high yield savings accounts earn between 4% and 5% annually right now, which means a $10,000 balance generates roughly $400 to $500 in interest per year. On a $100,000 balance, that is $4,000 to $5,000. All of that interest is taxable income in the year you earn it, whether you withdraw it or leave it in the account.
Your state may also tax this interest. Some states tax savings interest at the same rate as federal income tax. Others tax it at a lower rate or not at all. If you live in a state with no income tax — Florida, Texas, Wyoming, Alaska, South Dakota, Nevada, Washington, or Tennessee — you owe federal tax only.
Key Takeaways
- Savings account interest is taxed as ordinary income at your federal tax bracket rate, not at a flat rate.
- You report interest income on your tax return; the bank does not automatically withhold federal tax from your account.
- Banks send you a 1099-INT form by January 31 each year if you earned $10 or more in interest during that year.
- State income tax on savings interest varies by state — nine states have no income tax at all.
- The interest you earn is taxable in the year you earn it, even if you do not withdraw the money.
When the bank reports your interest to the IRS
Your bank sends you and the IRS a Form 1099-INT by January 31 each year if you earned $10 or more in interest during that calendar year. This form lists the total interest you earned across all accounts at that bank. If you have accounts at multiple banks, you receive a separate 1099-INT from each one.
You do not have to wait for the 1099-INT to report your interest income. You can calculate it yourself by adding up the interest deposits that appeared in your account during the year. Many banks also show your year-to-date interest in the account dashboard or in your monthly statements. If you earned less than $10 in interest, the bank does not send a 1099-INT, but you still owe tax on that interest if your total income requires you to file a return.
The IRS receives a copy of your 1099-INT at the same time you do. If the interest amount on your return does not match what the bank reported, the IRS will flag it. For this reason, report the amount shown on the 1099-INT even if you calculated something different — if there is a discrepancy, contact the bank to correct it before filing.
How your tax bracket determines what you actually owe
Your tax bracket is determined by your total income for the year, not by the source of that income. If you earn $50,000 in wages and $500 in savings interest, your taxable income is $50,500. The interest is taxed at whatever marginal rate applies to that $50,500 — not at a special rate for interest.
For 2024, the federal tax brackets are: 10% on income up to $11,600 (single filer), 12% from $11,601 to $47,150, 22% from $47,151 to $100,525, and so on. If you are single and earn $45,000 in wages, you are in the 12% bracket. If you then earn $3,000 in savings interest, that $3,000 is taxed at 12%, meaning you owe $360 in federal tax on it. If you earn $60,000 in wages instead, you are in the 22% bracket, and the same $3,000 in interest costs you $660.
This is why the interest rate advertised by the bank is not the same as the interest rate you keep. A 5% APY account earning $500 in interest costs you $120 in federal tax if you are in the 24% bracket, leaving you with $380 in actual after-tax interest.
State tax on savings interest varies widely
Nine states — Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire — have no state income tax. If you live in one of these states, you owe only federal tax on your savings interest.
Most other states tax interest income at the same rate as wages. California taxes it at up to 13.3%. New York taxes it at up to 10.9%. Some states offer a small deduction or exemption for interest earned on savings accounts specifically, but this is rare and usually applies only to accounts held for a minimum time or with a minimum balance.
A few states — Illinois, Mississippi, and Missouri — exempt interest income from state tax entirely, even though they tax wages. If you live in one of these states, you owe federal tax on your savings interest but no state tax.
How to calculate your after-tax interest earnings
Start with the interest rate your bank advertises. Multiply it by your account balance to find your annual interest in dollars. Then subtract the federal tax you will owe, based on your tax bracket. Then subtract state tax if your state taxes interest income.
Example: You have $50,000 in a high yield savings account earning 4.5% APY. Your annual interest is $2,250. You are a single filer in the 22% federal tax bracket and you live in Colorado, which taxes interest at the same rate as wages (22%). Your total tax is 44%, or $990. Your after-tax interest is $1,260.
Another example: Same account, same balance, same interest. You are in the 12% federal bracket and you live in Florida, which has no state income tax. Your total tax is 12%, or $270. Your after-tax interest is $1,980. The difference between the two scenarios is $720 per year, even though the account itself is identical.
This calculation assumes your tax bracket does not change during the year. If you expect a significant change in income — a job loss, a large bonus, retirement — recalculate your estimated tax bracket before the year ends.
Interest earned in retirement accounts is not taxed the same way
If you hold a high yield savings account inside a traditional IRA or 401(k), the interest is not taxed in the year you earn it. Instead, you pay tax when you withdraw the money in retirement, at whatever your tax bracket is then. This is called tax-deferred growth.
If you hold a high yield savings account inside a Roth IRA, the interest is never taxed at all, as long as you follow the withdrawal rules. You can earn interest for decades and pay zero federal tax on it.
High yield savings accounts held in regular taxable accounts — the kind most people use — follow the ordinary income tax rules described above. The tax advantage of retirement accounts is one reason people prioritize funding them before opening taxable savings accounts.
Frequently Asked Questions
Do I have to pay taxes on interest if I do not withdraw it?
Yes. Interest is taxable income in the year you earn it, whether you withdraw it, leave it in the account, or transfer it to another account. The IRS taxes accrued interest, not withdrawn interest.
What if I earned less than $10 in interest — do I still owe tax?
The bank does not send a 1099-INT if you earned less than $10, but you still owe tax on that interest if your total income requires you to file a return. Report it on your tax return even without a 1099-INT.
Can I deduct savings account fees from my interest income?
No. Interest income is reported as a single number on your tax return. You cannot reduce it by subtracting fees. However, some investment-related fees may be deductible in other ways — consult a tax professional about your specific situation.
Does moving money between high yield savings accounts trigger taxes?
No. Transferring your balance from one account to another is not a taxable event. Only the interest you earn is taxable, not the principal you move.
What if my bank reports the wrong amount on the 1099-INT?
Contact the bank and ask them to issue a corrected 1099-INT. Once they send the correction to you and the IRS, report the corrected amount on your tax return. Keep documentation of the correction in case the IRS questions the discrepancy.
