You must report savings account interest if you earned more than $5 in a year, but most people with ordinary savings accounts will not reach that threshold
The IRS requires you to report interest income from a savings account on your federal tax return if the total interest you earned in a calendar year exceeds $5. This is a real threshold — if you earned $4.87 in interest, you do not have to report it. If you earned $5.01, you do.
Most savings accounts earn so little interest that the $5 rule eliminates the reporting requirement entirely. A savings account with $1,000 earning 0.01% annually generates 10 cents in interest. Even $10,000 at 4.5% (a high rate for regular savings) produces $450 in interest — which you would report — but the vast majority of people with modest balances will stay well below $5.
Your bank will send you a Form 1099-INT if you earned $10 or more in interest during the year. If you earned between $5 and $9.99, you still have to report it, but your bank will not send a form. You report it yourself on your tax return.
Key Takeaways
- You must report savings interest over $5 per year, even if your bank does not send you a form.
- Your bank sends Form 1099-INT only if interest reached $10 or more, but the $5 threshold still applies.
- Interest income is taxed as ordinary income at your regular tax rate, not at a special rate.
- High-yield savings accounts and money market accounts follow the same $5 reporting rule as regular savings accounts.
How the $5 threshold works in practice
The $5 rule is a filing threshold, not a tax threshold. You owe tax on all interest you earn, regardless of amount — but you only have to report it on your return if it crosses $5. The IRS does not care about $3 in interest; they care about $3,000.
Interest is calculated daily and paid monthly or quarterly, depending on your bank. If you have $5,000 in a high-yield savings account earning 4.5% annually, you earn roughly $187.50 per year, paid in small chunks each month. You will definitely report it. If you have $500 in the same account, you earn about $18.75 per year — still reportable, still above $5.
The threshold resets each calendar year. Interest you earned in 2023 does not count toward your 2024 threshold. Each year stands alone.
When your bank sends Form 1099-INT and what it means
If your interest income reached $10 or more during the calendar year, your bank will mail you a Form 1099-INT by January 31 of the following year. This form shows the total interest you earned and goes to the IRS at the same time it goes to you. The IRS already knows about this income before you file.
The form lists your name, address, Social Security number, and the bank's name and routing number. Box 1 shows the interest paid. If you earned interest from multiple banks, you will receive a separate 1099-INT from each one.
You do not mail the 1099-INT to the IRS yourself. Your bank does that. You keep your copy and use the number from Box 1 when you file your return. If you file electronically, the software will ask you to enter this amount. If you file by paper, you report it on Schedule 1 (Form 1040) or on your 1040 directly, depending on your filing method.
Interest between $5 and $9.99 that does not trigger a 1099-INT
If you earned interest but it fell between $5 and $9.99, your bank will not send a 1099-INT. You still have to report this income on your tax return. You report it the same way you would report interest from a 1099-INT — on Schedule 1 or directly on Form 1040 — but you write in the amount yourself.
This situation is less common now because interest rates have risen and high-yield accounts are more accessible. But it can happen with very small balances or with banks that pay interest quarterly rather than monthly. If you are unsure whether you crossed $5, check your year-end statement or call your bank and ask for the total interest paid in the calendar year.
How interest income is taxed
Interest from a savings account is taxed as ordinary income at your regular tax rate. If you are in the 22% tax bracket, you pay 22% on your interest income. There is no special rate for savings interest, no deduction, and no exemption based on how long you held the money.
This matters because it means the tax you owe depends on your total income for the year, not just on the interest. If you earned $50,000 in wages and $500 in interest, that $500 is taxed at whatever bracket your total income puts you in. If you earned $20,000 in wages and $500 in interest, the tax rate on that interest is different.
If you are married filing jointly, both spouses' interest income combines. If you each have separate savings accounts, you add both together to see if you crossed the $5 threshold.
Multiple accounts and combined interest
If you have savings accounts at more than one bank, you add up the interest from all of them to determine whether you crossed $5. Each bank will send you a separate 1099-INT if that bank's interest reached $10, but the IRS expects you to report your total interest income from all sources.
You report each 1099-INT separately on your return, but the total is what matters for your tax liability. If Bank A paid you $6 in interest and Bank B paid you $4, you received two 1099-INTs (or one from Bank A and nothing from Bank B, depending on the amounts), but you report both and your total interest income is $10.
High-yield savings accounts, money market accounts, and regular savings accounts all follow the same rule. Interest is interest, regardless of the account type or the rate.
What happens if you do not report interest income
If you earned $10 or more in interest, your bank reported it to the IRS on a 1099-INT. The IRS has a copy of that form. If you do not report it on your return, the IRS will notice the discrepancy when they match your return against the 1099-INT they received. This can trigger a notice asking you to explain the difference or pay additional tax plus interest and penalties.
If you earned between $5 and $9.99 and did not report it, the IRS has no independent record — your bank did not send a form. But you are still required to report it. The risk is lower, but the requirement is the same.
The safest approach is to report all interest income, even small amounts. The tax on $5 in interest is less than a dollar. The penalty for not reporting it is not worth the risk.
Frequently Asked Questions
Do I have to report interest if I earned less than $5?
No. The IRS has a $5 threshold for reporting interest income. If you earned $4.99 in interest during the year, you do not have to report it on your tax return. You still owe tax on it in theory, but the IRS does not require you to report amounts below $5.
What if my bank did not send me a 1099-INT but I earned more than $10 in interest?
Contact your bank when ready. Banks are required to send a 1099-INT if interest reached $10. If you earned $10 or more and did not receive one by February 15, ask the bank to issue a corrected form or a duplicate. The IRS expects to see a 1099-INT for that income, and you need it to file accurately.
Do I report interest from a savings account I opened for my child?
If the account is in your child's name and Social Security number, your child reports the interest on their return (or you report it on their behalf if they are a dependent and you file for them). If the account is in your name but held for your child's benefit, you report the interest. The person whose Social Security number is on the account is responsible for reporting.
Is interest from a savings account taxed differently than interest from a CD or money market account?
No. All interest income is taxed as ordinary income at your regular tax rate, regardless of the account type. A savings account, CD, money market account, or any other interest-bearing account follows the same $5 reporting threshold and the same tax treatment.
What if I moved money between banks during the year and earned interest at both?
You add up all interest from all banks for the calendar year. If the total reached $5 or more, you report it. Each bank that paid you $10 or more will send a separate 1099-INT, and you report each one on your return. The total interest is what matters for your tax liability.
