Seeing a credit name does not establish eligibility, and credits are not the same as deductions.
A form label is not an eligibility conclusion, and no calculator on this site supplies a line-by-line filing result.
Important limitations
This guide omits many definitions, exceptions, elections, worksheets, attachments, and special situations. It does not determine filing requirements or tell a visitor what to enter on a line.
