Hawaii Federal Tax ID / EIN numbers are valid in all fifty states. Many states issue "state tax IDs", which can go by names like sales tax number, resale number, and wholesale number. But any Hawaii business that requires a state tax ID will also require the nine-digit Hawaii Federal Tax ID that you can acquire right here.

Federal Tax IDs can go by many names in Hawaii, including:

Employer Identification Number (EIN)
Federal Employer ID Number (FEIN)
Federal ID Number (FIN)
Federal Tax Number (FTN)
Taxpayer Identification Number (TIN)
Federal Taxpayer Identification Number (FTIN)
Or often times, just Tax ID or Tax Number

Generally, Hawaii businesses need a Federal Tax ID.

Establishing a new Hawaii EIN number / Federal Tax ID is often one of the first things a new Hawaii business does. One common reason is that most business license applications will ask for the ID.
