    Tax Filing Tips from the Hawaii Department of Taxation

    Hawaii Individual Income Tax Forms
      Download and print PDF forms and instructions for Hawaii Residents (N-11) and Non-Residents (N-15) HERE.
      Limited quantities of printed forms may be picked up at all tax offices and Hawaii State Public Libraries.
      E-file Form N-11, Hawaii Resident Income Tax Return, for free on HTO (Click on “File Return” and select N-11.)

    Hawaii Business Tax Forms (General Excise, Transient Accommodations, Withholding)
      Business tax types may e-file on HTO for free. If filing on paper, use revision year 2017 for tax year 2018, and revision year 2018 for tax year 2019.
      Changes have been made to the mailing of booklets for GE, TA, and WH tax types. Forms will no longer be customized and bound in a booklet. Instead, a packet of blank forms will be mailed only to those who returned the request form by July 31, 2019. This is the last year we will mail forms.

    Treasury Offset Program Intercepts
      If you have an outstanding Hawaii tax debt, the federal government’s Treasury Offset Program allows the Hawaii Department of Taxation (DOTAX) to intercept your federal income tax refund to offset your Hawaii tax debt.
      In late February, DOTAX began sending letters of intent to offset to taxpayers with outstanding Hawaii tax debt via certified mail. If you received a notice of intent to offset, any federal income tax refund you may receive will be intercepted by DOTAX to offset your Hawaii tax debt. To prevent the interception of your federal income tax refund, within 60 days of the notice, you must pay your debt in full, request a review of your debt by providing proof of payment, or submit a copy bankruptcy document.
      If you are already on a payment plan, your federal income tax refund will be intercepted, which may reduce the length of your agreement, but does not change your payment amount or due dates.
      You may pay your debt online at HTO, by mailing a check using the payment voucher enclosed in the letter you received, or in person at any tax office.
      Should you have any additional questions, you may call the DOTAX Collection branch at (808) 587-1600. Due to the high call volume, we would appreciate your patience and understanding as we work with you to resolve your debt.
