The Hawaii Department of Taxation uses the term "Hawaii tax I.D." to refer to the unique account identification number assigned to each tax account. This is different from a Social Security number.
The Hawaii tax I.D. starts with a two-letter account type identifier followed by 12 digits. The "GE" account type stands for General Excise/Use and County Surcharge Tax.
You can register online and receive your tax I.D. by filing Form BB-1 through Hawaii Business Express . To learn more about Hawaii tax I.D. numbers, see items 12 - 19 of this edition of Hawaii's Tax Facts publication.
