Hawaii Filing Due Date: Individual income tax returns are due by April 20 — or by the 20th day of the 4th month following the end of the taxable year (for fiscal year filers).
Extended Deadline with Hawaii Tax Extension: Hawaii offers a 6-month extension, which moves the filing deadline to October 20 (for calendar year filers).
Hawaii Tax Extension Form: Hawaii’s tax extensions are automatic, so there is no request form or application to submit. You will automatically receive a Hawaii extension as long as you’ve satisfied all of the following 4 conditions:
• 100% of your properly estimated Hawaii tax liability is paid by the original due date (April 20),
• Your Hawaii tax return is filed by the extended due date (October 20),
• Your tax return includes full payment for any Hawaii tax not already paid, and
• There is no court order requiring you to file your Hawaii tax return before the established due date
NOTE: Failing to fulfill all 4 of the above requirements will make your Hawaii extension null and void.
Hawaii Extension Payment Requirement: An extension of time to file is not an extension of time to pay your Hawaii income tax. All state tax payments are due by the original deadline of the return. Any Hawaii tax not paid by the proper deadline will be subject to interest and penalties. In order to obtain Hawaii’s automatic extension, you must pay 100% of your state tax liability by the original due date. You can make a Hawaii extension payment with Form N-101A, or pay electronically using Hawaii’s Electronic Services portal: tax.hawaii.gov/eservices
Hawaii Tax Extension Tip: If you owe zero Hawaii income tax, you will automatically be granted a Hawaii tax extension. In this case, you don’t need to submit anything in order to extend your Hawaii filing deadline.
