Hawaii has a general excise tax on the business's gross receipts, not a sales tax, and on Oahu, the City and County of Honolulu, the rate on most services is 4.5%: 4% state GET plus a 0.5% county surcharge effective through December 31, 2030. Cleaning falls under the general rule for services, though no Department of Taxation source naming cleaning or listing exemptions for it was checked. A business may visibly pass GET on to customers, up to a maximum rate of 4.7120% on Oahu.
In Honolulu the tax question isn't what to add to the customer's bill. It's what the business owes on what it takes in. This page covers the Oahu rate and how it's built, the lower rate for subcontracted work, the state minimum wage, and what GET means for your books. Payroll registration and the employee test are on bookkeeping for Hawaii cleaning businesses.
How the 4.5% on Oahu is built
The Hawaii Department of Taxation's GET page sets the state rate at 4% for most activities, including services. The City and County of Honolulu adds a 0.5% county surcharge, effective January 1, 2007 through December 31, 2030, and the surcharge is added only to activities taxed at the 4.0% rate. Together that's 4.5%. Passing GET on to customers is optional, and the department caps the visible pass-on rate on Oahu at 4.7120%; that's a ceiling on what can be passed on, not the tax rate.

Subcontracted cleaning and the 0.5% rate
GET is a tax on the business's gross receipts, not a sales tax charged on the buyer. Subcontracted, or wholesale, services are taxed at 0.5%, and the county surcharge doesn't apply to activities taxed at 0.5%. Cleaning itself is subject to GET under the general rule covering services; no Department of Taxation source naming cleaning or janitorial service, or listing exemptions for it, was checked. More is on my page on Hawaii's general excise tax and cleaning, and how a particular job is taxed is a question for your CPA.

Wages in Honolulu
Hawaii's minimum wage is $16.00 an hour, effective January 1, 2026, and the next announced change is $18.00 on January 1, 2028. This page doesn't cover any City and County of Honolulu wage rule.

What GET means for your books
GET changes how a Honolulu job looks in the books. Think of the 4.5% less as a line on the customer's bill and more as part of the cost of the work: it's figured on your gross receipts, it's made of 4% state GET and the 0.5% county surcharge, and it's the business's tax whether the invoice passes it along or not. Where GET is passed on, the amount collected is tracked so it can be matched against what's owed, and receipts from subcontracted work taxed at 0.5% get their own income line. Labor goes into payroll at the wage actually paid.
I'm a bookkeeper, not a CPA or an Enrolled Agent. I keep GET and gross receipts recorded; how your receipts are taxed and reported is a question for your CPA.
