- 1.1% to 11% plus GET
Hawaii's top marginal rate of 11% is the third highest in the country, layered over a General Excise Tax. Unlike every other state, Hawaii taxes *gross receipts* rather than net income: the GET is a cost of doing business that applies before you net out expenses, which materially changes the real cost of a Hawaii operation.
Local taxes: There are no county income taxes in Hawaii, but the state GET and the county General Excise Tax on services both apply. Honolulu also charges a county GET on contracting services, so a Honolulu-based contractor pays two excise taxes on gross revenue.

Tax Strategy for consultants
A consultant's deduction profile is dominated by the home office, professional liability insurance, and continuing education, which is a required cost of maintaining a licence or certification. Professional liability insurance is frequently overlooked and is fully deductible as an ordinary and necessary business expense, as is the cost of the credentials clients increasingly require.
Consulting revenue often arrives in large retainers or milestone payments rather than monthly hours. If a client pays a quarterly retainer in advance, the income is taxable on receipt, which can push a single quarter's liability well above a straight-line division of the annual total.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.
