Interest counts as income the IRS expects you to report
Yes, interest you earn in a savings account is taxable. The IRS treats it as ordinary income, the same way it treats wages or self-employment earnings. You owe federal income tax on every dollar of interest your bank pays you, no matter how small the amount.
Your bank will send you a Form 1099-INT each January if you earned $10 or more in interest during the previous year. That form goes to the IRS too. Even if your bank does not send you a 1099-INT because your interest was under $10, you still owe tax on it — you just have to report it yourself on your tax return.
The tax rate you pay depends on your overall income and tax bracket. Interest is not taxed at a special rate; it is added to your other income and taxed at whatever rate applies to your total earnings for the year.
Key Takeaways
- All interest earned in a savings account must be reported as income on your federal tax return, regardless of the amount.
- Banks send Form 1099-INT to you and the IRS when interest reaches $10 or more in a calendar year.
- Interest is taxed as ordinary income at your regular tax rate, not at a special rate.
- State and local income taxes may also explore to savings account interest, depending on where you live.
- High-yield savings accounts earn more interest, which means you owe more tax on those earnings.
When your bank sends you a 1099-INT form
Your bank is required to issue a Form 1099-INT if you earned $10 or more in interest during the calendar year. The bank mails it to you by January 31 of the following year. That same form is filed with the IRS, so the agency already knows about your interest income before you file your return.
If you earned less than $10 in interest, your bank will not send a 1099-INT. However, you are still required to report that interest on your tax return. The IRS matches 1099 forms against tax returns, so if your bank reported interest and you did not claim it, the mismatch will be flagged.
Keep your 1099-INT forms in your tax records. You will need the exact interest amount when you file. If you have accounts at multiple banks, you will receive a separate 1099-INT from each one.
How interest income affects your tax bracket and refund
Interest is added to your other income — wages, self-employment earnings, investment gains — to calculate your total taxable income for the year. That total determines which tax bracket you fall into and how much you owe.
If you are in a lower tax bracket, the interest may be taxed at 10% or 12%. If you are in a higher bracket, it could be taxed at 22%, 24%, or higher. A person earning $50,000 in wages plus $500 in interest will owe tax on $50,500 total, not just the wages.
This matters most if you are close to a tax bracket boundary. An extra $1,000 in interest could push you into the next bracket and increase the tax rate on some of your income. It can also affect whether you owe the Alternative Minimum Tax or lose certain deductions that phase out at higher income levels.
State and local taxes on savings interest
In addition to federal tax, most states tax interest income. The rate varies by state. Some states tax interest at the same rate as ordinary income; others have a flat rate. A few states do not tax interest at all.
New Hampshire and Tennessee, for example, do not tax interest income. Most other states do. If you live in a state with income tax, you will report the same interest amount on your state return that you reported to the IRS.
Some cities also impose local income tax. If you live in a place with both state and local income tax — such as New York City or Philadelphia — you may owe tax on your interest at all three levels: federal, state, and local.
Why high-yield savings accounts create a larger tax bill
High-yield savings accounts currently pay 4% to 5% annual interest, compared to 0.01% or less at traditional banks. That higher rate means significantly more interest income — and significantly more tax owed.
A $10,000 deposit in a high-yield account earning 4.5% generates $450 in annual interest. At a 22% federal tax rate, you owe $99 in federal tax on that interest alone. Add state tax and the bill grows. A traditional savings account earning 0.01% on the same $10,000 generates only $1 in interest and essentially no tax.
This does not mean high-yield accounts are a bad choice. The interest you earn is still yours to keep after taxes. But it is important to understand that the higher earnings come with a higher tax bill, and you need to set aside money to pay that tax when it is due.
How to report interest on your tax return
If you file Form 1040 (the standard individual income tax return), interest income goes on Schedule 1, line 8. You add it to your other income sources to calculate your total income.
If you use tax software, the program will ask you to enter the interest amount from your 1099-INT forms. If you file by hand, you write the total interest from all your accounts on the appropriate line.
Keep your 1099-INT forms and bank statements together in your tax file. If the IRS ever questions your return, you will need to show proof of the interest you reported. The IRS has copies of the 1099-INT forms your banks filed, so the numbers must match.
What happens if you do not report interest income
The IRS receives copies of all 1099-INT forms filed by banks. If your return does not include interest that was reported to the agency, you will likely receive a notice asking you to explain the discrepancy. The IRS will calculate what you owe, add penalties and interest charges, and send you a bill.
Penalties for not reporting income start at 20% of the unpaid tax. Interest accrues daily on the unpaid balance. If the IRS determines the omission was intentional, criminal penalties are possible, though they are rare for small amounts of unreported interest.
The simplest approach is to report all interest when you file, even if the amount is small. It takes minutes and avoids months of correspondence with the IRS later.
Frequently Asked Questions
Do I have to report interest if I earned less than $10?
Yes. Your bank does not send a 1099-INT for interest under $10, but you are still required to report it on your tax return. The IRS expects all interest income to be reported, regardless of amount.
Can I deduct the taxes I pay on savings interest?
No. Interest income is taxed, but you cannot deduct the tax itself as an expense. You pay tax on the full interest amount at your regular rate. Some investment expenses are deductible, but savings account interest is not.
What if I have interest from multiple banks?
Add up the interest from all your 1099-INT forms and report the total on your tax return. Each bank sends its own form, but you combine them into one line item on Schedule 1.
Does moving money between my own accounts count as taxable interest?
No. Transferring money from one account to another is not income. Only the interest the bank pays you is taxable. Moving your own money around does not create any tax event.
Is interest from a money market account taxed the same way?
Yes. Money market accounts, certificates of deposit (CDs), and other savings products all generate interest that is taxed as ordinary income. Your bank will send a 1099-INT for any of these accounts if interest reaches $10 or more.
