For disaster relief, requests can be made using Form L‑115A for Hurricane Lala and Form L‑115B for Hurricane Lowell.

Taxpayers may make tax payments online at Hawaiʻi Tax Online at https://hitax.hawaii.gov. If taxesare owed on the return, failure to pay by the deadline may result in the imposition of penalties and interest.

File Electronically

Taxpayers are encouraged to electronically file (e-file) their tax returns. E-filing reduces delays and speeds up processing times, resulting in faster refunds than those who file by paper.

Form G-45 and TA-1 may be e-filed for free using DOTAX’s online tax filing system, Hawaiʻi Tax Online (HTO) at https://hitax.hawaii.gov.

Form N-11 and N-15 may be e-filed for a fee using one of the approved commercial tax preparation software options provided at https://tax.hawaii.gov/eservices/software/.

Taxpayers may also e-file their Form N-11 for free using HTO at https://hitax.hawaii.gov.

Tax Forms

Tax forms and instructions are available to view, download and print online at https://tax.hawaii.gov/forms/. Printed tax forms and instructions are available for pick up at all state tax offices. Public libraries also carry printed N-11 and N-15 forms in limited quantities and haveprinted N-11 instructions available for reference use only.
