Updates for Taxpayers

Happy New Year! With the New Year, comes some updates and changes to help the Department of Taxation (DOTAX) better serve you.

We are open for business for the 2020 tax season! On January 2, 2020, all returns due in 2020 can be filed on HTO and all updated (Rev. 2019) paper forms will be posted on DOTAX’s website (tax.hawaii.gov/forms) and available at District Offices. [Please note: If you use third party software to submit your Hawaii income tax return, DOTAX will not receive your return until the IRS begins accepting returns on January 27, 2020.]

If you don’t already have an HTO account, we encourage you to sign up for one. HTO allows you to file returns, make payments, check account balances, manage DOTAX issued licenses/permits, and more. Transactions are fast, accurate, and secure.

Please read on for changes in effect this year.


Some of our forms have changed for 2020 to implement new rates, laws and processes. These forms are identified with “Rev. 2019.” To avoid processing delays, use the most current version of the form for the appropriate filing period.

*Not all forms change every year. To ensure that you are using the appropriate form version for the period you are filing for, log onto HTO to file electronically or access the forms page on DOTAX’s website. Using the correct form Rev. ensures that the tax rates are correct and your return will not be unnecessarily delayed.
