The main purpose of this legislation, known as the FIGHTER Act of 2025, is to provide tax relief for members of the Armed Forces by exempting their regular compensation for active service from federal income taxes. The goal is to recognize and support military personnel by allowing them to keep more of their earnings. Key provisions of the Act include a specific amendment to the Internal Revenue Code that states regular compensation received by active service members of the Armed Forces will not be included in their gross income for tax purposes.
