Withholding Tax – For Employers


Employers need to withhold Hawaii income taxes on employee wages. Employers then pay the withheld taxes to the State of Hawaii, Department of Taxation (DOTAX). Employees reconcile their withholding taxes paid as part of their Individual Income tax return. Withholding is required on:
  (a) Wages for services performed in the State.
  (b) Wages for services performed outside the State if:
    1. The services are performed by an employee whose regular place of employment for services for the employer is in the State; OR
    2. The wages are paid out of an office in the State or a field office of an employer whose head office is in the State.

Federal withholding rates are subject to change by the IRS. For information on Hawaii rates, please refer to the Appendix of Booklet A, Employer’s Tax Guide for tax withholding rates and tables.

All withholding taxpayers need to file returns quarterly (due April 15, July 15, October 15, and January 15) using Form HW-14. If changes need to be made to a return already submitted, please file an amended return for that filing period.

Reminder for W-2 or HW-2 Submittal

Beginning Tax Year 2020, the Form HW-3, Employer’s Return and Reconciliation of Hawaii Income Tax Withheld from Wages, is not required. Form HW-30, a simple transmittal for W-2 or HW-2 forms, is only required for paper submissions of W-2 or HW-2 forms.

Effective January 1, 2022, Form W-2/HW-2 must be filed with the Department of Taxation (Department) and furnished to the employee no later than January 31st following the close of the calendar year. Please see Tax Announcement 2021-08 for more details.

Taxpayers using Hawaii Tax Online will be asked to submit the W-2 or HW-2 forms by (1) manually entering the data into the web form, (2) using simple file upload with Excel, or (3) upload using the bulk filing system (a.k.a., FSET).

Frequently Asked Questions (FAQs)


How do I get a withholding (WH) account number?

Use Form BB-1 to request a withholding (WH) account number. You may also add a withholding account on Hawaii Tax Online if you already have a login.

How much does it cost to obtain a Withholding account?

There is no fee to open a withholding account.

Can I e-pay or e-file my returns?

Absolutely! All taxpayers are encouraged to e-file or e-pay to ensure that transactions are posted quickly and accurately.

Do I need to issue employees Form W-2/HW-2?

Yes, issue employees Form W-2 or HW-2 by January 31 and submit a copy of the Form W-2 or HW-2 information to DOTAX by February 28 using Form HW-3.

What’s the difference between IRS Form W-2 and Hawaii Form HW-2?

The forms are essentially the same. Either can be issued to your employees. DOTAX accepts the IRS Form W-2 or our Form HW-2.

Why do I have two (2) withholding tax account numbers, one with an “R” at the end?

Each withholding taxpayer has two tax numbers:

  • WH-###-###-####-01 is the withholding periodic account.
  • WH-###-###-####-01R is the withholding annual/reconciliation account.

The account is generally referred to without the “R” at the end. The account with the “R” at the end is used to reconcile your withholding accounts annually. [NOTE: Taxpayers who open a withholding account after January 1, 2020 will only have one tax number. No “R” account will be assigned.]

If I hire seasonal, part-time, and full-time employees in the State of Hawaii, do I need to withhold taxes for all types of employees?

Yes. Any payment of wages to employees may be subject to withholding tax. Please refer to Booklet A, Employer’s Tax Guide (Revision 2017) for more information on withholding requirements.

Other FAQs

Please send a copy of the Form HW-4 for that employee to the Tax Assessor in the district office where you file your withholding tax returns. For more information relating to withholding allowances see Tax Information Release No. 95- 4.
