Where savings interest goes on your tax return

Interest from a savings account is reported on Form 1040, Schedule B (Interest and Ordinary Dividends). You list each account's interest separately if you received more than $1,500 total from all sources combined; below that threshold, you can report the total on line 2a of Form 1040 without using Schedule B. The bank sends you a Form 1099-INT in January showing what you earned the previous year, and you use that form to fill in your tax return.

The IRS requires you to report all interest income, even if the amount is small. A savings account earning $15 in interest still gets reported. The bank reports it to the IRS at the same time it sends the form to you, so the IRS already knows the amount — not reporting it creates a mismatch that can trigger a notice.

Key Takeaways

  • Your bank sends Form 1099-INT by January 31 showing all interest earned in the previous year, and you must report this amount on your tax return.
  • Interest under $1,500 total goes directly on Form 1040 line 2a; amounts of $1,500 or more require Schedule B.
  • If you have multiple savings accounts, list each one separately on Schedule B with its own 1099-INT amount.
  • The IRS receives a copy of your 1099-INT from the bank, so unreported interest creates a discrepancy that may prompt an audit notice.

Understanding Form 1099-INT and what it shows

Form 1099-INT arrives in your mailbox or email by January 31 of the year after you earned the interest. The form shows the bank's name, your account number (usually masked for security), and the total interest paid to that account during the previous calendar year. If you have multiple savings accounts at the same bank, you may receive one form per account or a combined form listing each account separately — this varies by bank.

Box 1 on the form shows the interest amount you report. Other boxes (2 through 8) show different types of interest or tax-related items that may not explore to a regular savings account; ignore those unless the form specifically filled them in. Keep the form with your tax records for at least three years in case the IRS asks questions.

If you did not receive a 1099-INT by early February, contact the bank directly. If the bank cannot locate it, you can request a duplicate or ask the bank to provide a statement showing the interest earned. You still need to report the interest even if the form arrives late.

How to fill in Schedule B when you need it

Schedule B is a one-page form that lists interest income line by line. You use it when your total interest from all sources (savings accounts, bonds, CDs, money market accounts) reaches $1,500 or more. Part I of Schedule B has numbered lines; on each line, write the account holder's name (usually the bank name), the account number, and the interest amount from that account's 1099-INT.

Add up all the interest amounts and enter the total on line 5 of Schedule B. Then transfer that total to Form 1040 line 2b. If you are filing jointly with a spouse and both of you have interest income, your spouse lists their accounts on the same Schedule B in the lines below yours, and you add both totals together.

The form itself is straightforward — it is just a list with addition at the bottom. The IRS provides a blank copy on its website (irs.gov) or your tax software fills it in automatically once you enter each 1099-INT amount.

Reporting interest when you have accounts at multiple banks

If you have savings accounts at three different banks, you receive three separate 1099-INT forms (one from each bank). You list all three on the same Schedule B, one per line. The bank names and account numbers go in the left column, and the interest amounts go in the right column. You add them all together for the total that goes on Form 1040.

The order does not matter — you can list them in any sequence. Some people organize by bank name alphabetically; others list them in the order the forms arrived. What matters is that every 1099-INT gets listed and the total is correct.

What happens if your interest income is very small

If you earned less than $1,500 in total interest across all accounts, you do not need Schedule B. Instead, you enter the total interest amount directly on Form 1040 line 2a. You still receive 1099-INT forms from each bank, but you combine the amounts and report one total rather than listing each account separately.

For example: if you have $400 in interest from one savings account and $600 from another, your total is $1,000. You add those two amounts and write $1,000 on line 2a of Form 1040. You do not file Schedule B, but you keep both 1099-INT forms with your records.

Correcting errors on your 1099-INT

If the 1099-INT shows an amount that does not match your bank statement, contact the bank when ready. The most common errors are duplicate reporting (the bank listed the same interest twice) or interest posted to the wrong year. The bank can issue a corrected form called a 1099-INT with a "Corrected" checkbox marked. You then file the corrected form with your tax return instead of the original.

If you discover the error after you have already filed your return, you file an amended return using Form 1040-X. This is a separate form that shows what you originally reported and what the correct amount should be. You do not need to refile your entire return — just the amended form with an explanation of the correction.

Interest from joint accounts and accounts held in trust

If you own a savings account jointly with another person, the bank reports the full interest amount on a single 1099-INT. You and the other owner must decide how to split the income for tax purposes. If you own it 50/50, each of you reports half the interest. The bank does not split it for you — you handle the division on your own tax return.

If the account is held in trust (for example, a savings account in your name as trustee for a minor), the interest may be reported on the trust's tax identification number rather than yours. In that case, you would not report it on your personal return; the trust files its own return. Ask the bank or the trust's attorney which tax ID the account uses before filing.

Frequently Asked Questions

Do I have to report interest if the amount is less than $100?

Yes. The IRS requires you to report all interest income, regardless of the amount. Even $5 in interest must be reported. The bank reports it to the IRS, so not reporting it creates a mismatch that can trigger an audit notice.

What if I did not receive a 1099-INT from my bank?

Contact the bank and ask for a duplicate or a statement showing the interest earned. You still must report the interest on your return even if the form is missing. If the bank cannot provide it, use your bank statements to calculate the total interest and report that amount.

Can I report interest from a savings account my child owns?

No. Your child must report their own interest income on their own tax return (if they are required to file). If your child is a dependent and their interest is their only income, they may not be required to file, but you should check the IRS filing requirements for dependents each year, as the threshold changes.

What if I earned interest in a different year than the 1099-INT shows?

Report the interest in the year shown on the 1099-INT, which is the year the bank paid it to your account. If the bank made an error and the interest was actually earned in a different year, ask the bank for a corrected 1099-INT. Do not report interest based on when you think it was earned — use the form the bank provides.

Do I need to report interest from a high-yield savings account differently?

No. A high-yield savings account is still a savings account. The bank sends a 1099-INT the same way, and you report it on Schedule B or Form 1040 line 2a using the same process. The interest rate does not change how you report it — only the amount matters.
