E-filing information for 1120 Hawaii
Electronic filing mandate
Hawaii doesn't have an e-file mandate.
Returns supported for electronic filing
You can electronically file the following return types:
- C Corporation
- S Corporation
- Consolidated / combined
- Amended
- Short year
Returns not supported for electronic filing
You can't electronically file the following return types:

Signature requirements for electronic filing
Hawaii doesn’t have a specific signature form for business returns. Hawaii considers the act of completing and filing electronically an authorized signature.
Resubmit returns
If you need to make a change to a return that you have already electronically filed, and Hawaii has already accepted it, then amend and paper file the return. If Hawaii rejects the return, you may make the changes, correct the rejection, and resubmit.
Attachments
Hawaii requires a valid federal attachment in the electronic file. Therefore, if the federal return is not supported for electronic filing by the IRS, you can't e-file the state return.
Hawaii allows PDF attachments in the electronic file. Refer to the
PDF attachment
worksheet in Forms
view to review the PDFs that UltraTax CS automatically attaches. Hawaii has specific naming conventions when you attach PDFs; refer to Publication EF-8, Hawaii Software Developers and Transmitters Handbook for Corporate Modernized e-file for a list of accepted file names.Payment methods
Hawaii allows electronic funds withdrawal (direct debit), electronic funds transfer (EFT), or a check mailed with voucher for balance due returns.
Bank information and a requested payment date are required when you are requesting EFW. Hawaii will use the bank information you enter on the
Bank
federal screen. If you have different bank information for Hawaii, use the HIBank
screen in the General
folder.
