Hello, everyone.

My client, C corporation filed a Final Return that tax period was Aug, 2024.

They got a Refund with interest from IRS. That interest is $10,000 which IRS writes a letter that it said they has to file as a Interest income on March, 2025.

Should they file another Final Return that tax period is Aug, 2025?

Or should they amend their final tax return?

If they amend, they has to pay penalty because it was over the due date.

Please help.

Thank you for your support!!
