1099 INT with FBO Minor Child

it depends on whether your minor child is required to file a tax return.  You are not required to report it, unless you choose to,

• At what point does a child have to file a tax return?

The IRS also has a cutoff level for "unearned income," such as dividends or interest. If your child's income is above this year's level, they need to file; below that point, they aren't required to file a tax return. The amount for 2023 is $1,250.

If your child's income is less than the amount shown, you also are not required to include it on your tax return. If it's greater and there are no earnings such as wages you can choose to claim it only if you don't want to file for your child.

• Form 8814 - Parents use this form to report their child’s income on their return, so their child will not have to file a return.
