Businesses that have run payroll in Hawaii in the past can find their Tax ID on notices received from the Hawaii Department of Taxation, such as the Withholding Tax Return (Form HW-14), or by calling the agency at (800) 222-3229. The Hawaii Withholding ID number format is WH-000-000-0000-01 (or -02). The agency is no longer accepting customer IDs formatted as W00000000-00. If you have a number that starts with a W, you can find your new ID number by visiting this website and entering your old ID number
You can find your UI Account Number on notices received from the Hawaii Department of Labor and Industrial Relations, such as the Contribution Rate Notice, Quarterly Wage Report (Form UC-B6), or by calling the agency at (808) 586-8914. 

Contribution Rate: You can find your Contribution Rate on the Contribution Rate Notice that you have received from the Hawaii Department of Labor and Industrial Relations. It ranges from 0.0% – 5.6%, with a wage base of $45,900 in 2018. Please do not include the E&T rate component. If you're unsure, verify your rate by calling the agency at (808) 586-8915. 

Register a new company

Income tax withholding 

Register online with the Hawaii Department of Taxation. We recommend you start by using the Wizard to guide you through the process. The registration process can take 2-3 days. Please keep this time frame in mind when planning your first payroll in Hawaii. Alternatively, your request will be processed in 3 weeks if registering by mail, or same-day if you register in person at a local Hawaii Department of Taxation office. Note that the format of your Hawaii Withholding ID will be WH-000-000-0000-01 (or -02). 

Unemployment tax 

New employers in Hawaii will need to register online with the Department of Labor to obtain an account number within 20 days after hiring an employee. You should receive your number and contribution rate about 2 weeks after registering. The rate for a new employer is typically 2.4%. If you're unsure, verify your rate by calling the agency at (808) 586-8915. 

Temporary disability insurance

Hawaii employers are required to provide TDI (Temporary Disability Insurance) coverage for eligible employees to help cover nonwork-related injuries and illnesses. Employers can choose to cover the entire cost or withhold up to 0.5% of eligible employees' wages (not to exceed $5.34/week) to share the cost of coverage. 

Gusto does not handle TDI payments since these are sent to private TDI insurance carriers obtained by your company. If you elect to share the TDI cost with an eligible employee, we will still deduct this amount from the employee's wages when you run payroll. However, this amount will stay in your bank account so that you can pass this along to your insurance carrier.
