Final answer:
Kailani should report the interest income from her Form 1099-INT on her federal tax return, either on Schedule B or directly on Form 1040 in the 'Interest and Ordinary Dividends' section, depending on the total amount of her interest income.
Step-by-step explanation:
The income reported on Form 1099-INT for interest income that Kailani received from the lending bank should be reported on her federal tax return as income. Specifically, this interest income should be included on Schedule B (Form 1040A or 1040) if required or directly on Form 1040 (or 1040A) in the section for 'Interest and Ordinary Dividends' under the 'Income' category. If Kailani is required to fill out a Schedule B, she would list the total interest amount on Line 1. However, if the total amount of interest she received during the year is less than the threshold requiring a Schedule B, she would report it directly on her Form 1040 without needing to complete Schedule B.
As Kailani does not have any other interest or dividends to report, she does not need to concern herself with complicating her tax filing with additional schedules for other types of income. It is important to report this income to avoid any discrepancies with the IRS, as they will have received a copy of the Form 1099-INT from the lending bank as well.
