The General Excise Tax: a gross receipts tax, not a sales tax
If you're selling into Hawaii and treating it like any other state, you're already making a costly mistake. While most states tax the end consumer on retail purchases, Hawaii taxes your business on virtually all gross receipts — services, wholesale transactions, and B2B sales that would be exempt almost anywhere else.
The quick version: $100,000 in gross receipts or 200 transactions triggers registration. SaaS is fully taxable — there's no cloud carve-out.
The tax stacks up as a product moves through the supply chain ("pyramiding"). And if you pass the tax to your buyers, the amount you collect becomes additional taxable income.
Hawaii GET rate table
| Field | Value |
|---|---|
| State base rate | 4.0% |
| Average combined rate | 4.44% |
| Local add-on range | 0% to 0.5% |
| Maximum combined rate | 4.5% |
| Rates vary by county/city | Yes — 5 jurisdictions |
| Sourcing | Destination-based |
Four counties (Oahu, Hawaii Island, Maui, Kauai) add a 0.5% surcharge; Kalawao County has no surcharge.
$100,000 or 200 transactions — gross receipts, not just taxable sales
If your business makes more than $100,000 in gross receipts from Hawaii sales or hits 200 transactions in the current or prior year, Hawaii requires you to register. Notice it says gross receipts, not just taxable sales — that's a massive difference since Hawaii taxes almost everything.
- Marketplace sales count toward the threshold, but you're not separately liable once the marketplace collects GET.
- Register by the first day of the month following when you meet the threshold.
SaaS is fully taxable — no carve-out
GET isn't a "true object" test state. It's a gross receipts tax on business income. Unless an activity is specifically exempt, it's taxable — and digital goods and services aren't exempt.
| Product / service | Tax treatment |
|---|---|
| SaaS (B2B and B2C) | Taxable at 4% |
| Downloaded software (any license) | Taxable |
| Streaming / subscription software | Taxable |
| Digital goods (e-books, music, video) | Taxable |
| Data processing / cloud storage | Taxable |
The gross-up quirk: GET you collect from customers becomes part of your taxable receipts. Most businesses charge ~4.71% to break even instead of exactly 4%.
Everything is taxable — including groceries and prescriptions
| Product category | Tax treatment |
|---|---|
| Groceries & unprepared food | Taxable at 4% |
| Prepared food & restaurant meals | Taxable at 4% |
| Clothing & apparel | Taxable at 4% |
| Prescription drugs | Taxable at 4% — no exemption |
| Manufacturing machinery (retail) | Taxable at 4%; 0.5% if for resale/wholesale |
| Raw materials (wholesale, documented) | 0.5% |
Groceries and prescription drugs are taxable — most states give consumers a break here. Hawaii does not.
Hawaii does not offer sales tax holidays
Because GET taxes the business instead of the consumer, temporary tax breaks for shopping simply don't work administratively. GET applies year-round at the standard 4% rate plus surcharges.

Not home-rule — and not an SST member
Hawaii is not a home-rule state — one state registration covers GET statewide, including county surcharges. Hawaii is not an SST member and likely never will be, since GET works fundamentally differently from consumer sales taxes.
Voluntary Disclosure Agreement (VDA)
Hawaii offers a formal VDA program directly or through the MTC. Lookback reduced from 4 years to 3 years. Penalties waived; interest owed in full. Process takes 60-90 days.
Audit risk in Hawaii
Hawaii's Department of Taxation actively enforces its rules. The biggest trap: businesses underestimating GET's broad reach. Common triggers: service businesses assuming GET doesn't apply, high volume of wholesale-rate transactions without documentation, discrepancies between federal returns and GET filings. Statute of limitations: 3 years if filed; indefinite if never filed.
Recent changes & quirky rules
GET applies at every level of the supply chain — the same dollar can be taxed multiple times before reaching a consumer.
A valid resale cert drops GET from 4% to 0.5% — you still owe tax, just at the wholesale rate.
Exemptions & resale certificates
Hawaii uses Form G-16 (Resale Certificate), which reduces GET from 4% to 0.5% rather than eliminating it. Hawaii does not accept the SST Uniform Exemption Certificate. GET applies broadly with few true exemptions — wholesale/resale gets the reduced rate, but nonprofits, government, manufacturing, and healthcare generally have no blanket exemption. No direct pay permits.
Your next step: get clarity on Hawaii's GET
- Approaching $100,000 or 200 transactions? Register before you hit the threshold.
- Service business or SaaS provider? Don't assume exemption — GET applies broadly.
- Already registered? Verify your gross-up rate and county surcharge calculations.
