What's different about Hawaii for the self-employed
- Hawaii's general excise tax (GET) applies to the self-employed on gross receipts, not profit: 4% plus a 0.5% county surcharge in every county. It is separate from income tax and not included here.
- Personal exemptions for dependents and Hawaii's refundable food/excise credit are not included.
- Hawaii's General Excise Tax is levied on the business (not the customer) on gross receipts from virtually all business activities, including services; the rate is 4% for most activities plus a 0.5% county surcharge (Honolulu, Kauai, Hawaii County and Maui through 2030).
- A GET license is required to do business in Hawaii; registration (Form BB-1 or Hawaii Tax Online) costs a one-time $20 fee.
- Hawaii LLC annual reports ($15) can be filed any time during the quarter the report is due, which is tied to the entity's registration date (e.g., Q3 filers by September 30).
Hawaii estimated payments and deadlines
Hawaii collects its own estimated income tax with Form N-200V, separately from the IRS. Required if you expect to owe at least $500 in Hawaii tax after withholding and credits, and your withholding and credits will be less than the smaller of 60% of this year's tax or 100% of last year's tax.

LLC fees and sales tax in Hawaii
- Forming an LLC: $50 state filing fee.
- Annual Report: $15, every year, due by the end of the quarter your LLC registered in.
- General excise tax: 4% statewide, plus local rates. It is charged to the business on its gross receipts, including services, rather than added to a sale as a sales tax.
A single-member LLC is taxed exactly like a sole proprietorship unless it elects S or C corporation status, so the self-employment tax figures on this page apply either way.
