Answer: You can visit IRS website at www.irs.gov and go to forms and publication section, and search for form 1040. Alternatively, you can click the this link to download the Tax Form 1040.
The last date to file Tax Form 1040 is April 15. If you need to file an extension, file Form 4868. The extension form will give you an additional 6 months to file your tax return. Though any payment required must be sent before April 15 to avoid any penalties.
