Sales Tax on Cleaning Services in Hawaii (2025)

Hawaii Doesn't Have a Sales Tax at All. It Has the GET, and the Difference Matters

Ask a mainland accountant about Hawaii's "sales tax" and you will get an answer that misses the actual mechanics. Hawaii imposes a General Excise Tax (GET) under Hawaii Revised Statutes Chapter 237, administered by the Department of Taxation (DOTAX), and the GET is levied on the seller's gross income for the privilege of doing business in the state, not on the buyer's purchase. That legal distinction has a very practical consequence for cleaning operators: you cannot simply add a tax line labeled "sales tax" to an invoice the way you would in a true sales-tax state, because that is not what you are collecting. Most Hawaii businesses pass the GET through to customers as a separately stated charge, which is legal, but it must be identified correctly, and DOTAX has specific guidance on how that pass-through should be labeled and calculated to avoid pyramiding the tax on itself.

Services, including cleaning, janitorial, and maid services, are taxed under HRS §237-13 at the standard 4.0 percent state GET rate. On top of that, Honolulu County (the island of Oahu) imposes a county surcharge of 0.5 percent under HRS §237-8.6, bringing the effective combined rate on Oahu to 4.5 percent. The state's own Tax Facts 37-1 (revised May 2025) is the authoritative source for confirming current county surcharge status, since surcharge elections and rates have shifted across the neighbor islands over the past decade and should be verified against that document before finalizing any invoice rate for a specific county.

How the GET Applies to Cleaning Service Revenue by County

Registration Through Hawaii Tax Online and Sourcing Rules

Cleaning businesses register through Hawaii Tax Online (hitax.hawaii.gov) or by filing paper Form BB-1, obtaining a GET license before generating taxable gross income. Sourcing for services under Hawaii Administrative Rules §18-237-8.6-03 attaches to the place where the service is used or consumed, meaning a cleaning company headquartered on Oahu but sending a crew to a client property on Maui would need to apply Maui's applicable combined rate to that specific job, not Oahu's rate, since the service is consumed at the Maui location. For a business running crews across island lines, this requires tracking job-site county on every invoice rather than defaulting to your home county's rate.

DOTAX operates a toll-free assistance line at 1-800-222-3229 for registration and rate questions, which is worth using directly rather than relying on mainland-focused tax software defaults, since most off-the-shelf sales tax engines are not built around the GET's seller-liability structure and can misconfigure the pass-through calculation.

Worked Example: A $10,000 Monthly Contract on Oahu

For a cleaning business earning $10,000 in monthly gross income from a commercial contract on Oahu, the GET liability at the 4.5 percent combined rate is $10,000 × 0.045 = $450. Unlike a sales tax state, this $450 is technically the seller's own tax liability on gross income, not money held in trust for the state. If you choose to pass the cost through to your client as a separately stated visible charge, common practice, you would add the $450 to the invoice, but note that if you then owe GET on that pass-through amount itself (because the passed-through GET becomes part of your gross income), the effective rate on a fully grossed-up invoice can run slightly higher than a flat 4.5 percent. Many Hawaii businesses use a grossed-up multiplier for this reason rather than a simple percentage add-on; DOTAX guidance provides the correct multiplier tables to avoid under-collecting on the pyramiding effect.

Why "GET" Is Not Optional Terminology on Your Invoice

Labeling your pass-through charge "sales tax" on a Hawaii invoice is more than a cosmetic error. Because the legal incidence of the GET falls on the seller, mislabeling the charge can create confusion in a DOTAX audit about whether you understood your own liability structure, and it can create customer disputes if a client later checks their receipt against Hawaii's public consumer education materials, which explicitly explain that Hawaii has no sales tax and that the charge they are seeing is a general excise tax pass-through. Get your invoice template reviewed against current DOTAX guidance before your first commercial contract, and revisit it any time the county surcharge landscape shifts, since that has happened more than once over the past several years across the neighbor islands.

The general excise tax is not a sales tax, and treating it as one is the most expensive mistake a mainland contractor makes entering this market. The department's general excise tax overview explains that the tax is imposed on the business rather than the customer, which is why it applies to essentially all gross income including service revenue that would be exempt elsewhere. The AICPA state and local tax resource center is the better reference for modeling how that structure changes a bid built on mainland assumptions.

Registering a Cleaning Business Under a GET License, Not a Sales Tax Permit

A common early mistake among mainland transplants opening a cleaning business in Hawaii is searching for a sales tax registration process that simply does not exist here. What you register for is a GET license, obtained through Hawaii Tax Online or paper Form BB-1, and that license covers your gross income from every taxable activity you conduct, cleaning services, any retail sale of supplies, and any other business activity generating income, all under one account rather than separate registrations by activity type. DOTAX assigns a filing frequency, monthly, quarterly, or semiannual, based on your projected annual GET liability, and new businesses should expect to start on a more frequent filing schedule until a payment history establishes a lower-risk profile with the department.

Because the GET taxes gross income rather than net profit, a cleaning business operating on thin margins in a competitive market like Honolulu still owes GET on its full gross receipts, not on whatever remains after paying crew wages, fuel, and supplies. Building this into your pricing model from the start, rather than treating GET as an afterthought calculated at tax time, is the difference between a sustainable margin and a business that discovers its actual profitability is thinner than expected once the full-year GET liability comes due.
