Hawaii State Modernized E-File (MeF) Program

In conjunction with the Internal Revenue Service’s Modernized E-File Program, this program provides electronic filing and payment options for filers of Hawaii individual income tax.

Hawaii Forms Reproduction

In order to be acceptable for filing purposes, reproductions of Hawaii tax forms must meet certain conditions and requirements. A reproduced form is any Hawaii tax form that is not provided by Department of Taxation. If you are a software developer who would like to reproduce Hawaii tax forms, please see our software vendors website.
