1040 tax forms are available for free on the Internal Revenue Service website. The forms are in a PDF format and can be filled out on a computer.
In addition to the various 1040 forms, the IRS website provides instructions for each form, and taxpayers can prepare and file their federal tax forms online for free. The site offers taxpayers help with basic questions and a self-service system for checking on the status of filed returns. Taxpayers who find errors in their previously filed returns can make amendments online and check on the status of amended returns as well. The site also offers mailing addresses for those preferring to file paper returns.
