    Reminders as Tax Deadline Nears
    The Hawaii individual income tax return and payment for tax year 2018 was due Monday, April 22, 2019. However if you did not file by the April deadline, you are granted an automatic 6-month extension of time to file extending the deadline to October 20, 2019. Note that if you have a balance due, the extension of time to file is not an extension of time to pay. We encourage you to use Hawaii Tax Online to file and pay your taxes.
