Hawaii Self-Employed Tax Guide for 2026
Self-employed in Hawaii means juggling two different state taxes. There's the income tax, with brackets that climb to 11%, and there's the General Excise Tax — a tax on your gross receipts that most mainland freelancers have never heard of. Add deadlines that fall on the 20th instead of the 15th, and it's easy to get something wrong. Here's the 2026 playbook.
Hawaii's income tax brackets
Hawaii has twelve brackets from 1.4% to 11%. Act 46 is widening the brackets and raising the standard deduction in stages through 2031, so the same profit costs a little less each year. A gig worker with $55,000 of net profit typically pays an effective Hawaii income tax rate around 6% to 7%.
The General Excise Tax (GET)
GET applies to gross business receipts, not profit. It's 4% statewide and 4.5% on Oahu, Kauai, Maui and Hawaii Island because of county surcharges. Rideshare and delivery drivers, freelancers and short-term hosts generally need a GET license and must file Form G-45 periodically plus an annual G-49. Many businesses pass GET on to clients at about 4.712% (4.166% outside surcharge counties) to cover it.
GET is deductible
The GET you pay is a Schedule C business expense. That reduces your federal income tax, self-employment tax and Hawaii income tax, softening the double hit.
Deadlines on the 20th
Hawaii estimated payments on Form N-1 are due April 20, June 20, September 20, 2026, and January 20, 2027. The N-11 resident return is due April 20, 2027. Don't assume your federal reminders cover Hawaii.
Deductions that matter in Hawaii
High living costs make the home office deduction and the business share of phone and internet worth tracking. Driving distances are shorter than on the mainland, but mileage still counts: 72.5¢ per mile January–June and 76¢ July–December 2026.
How much to set aside
Plan on 30% to 35% of net profit for federal, SE and Hawaii income tax, and separately set aside 4% to 4.5% of gross receipts for GET. The Hawaii self-employed tax calculator estimates the income tax side.
