GET Calculation Summary

Understanding Hawaii GET vs Traditional Sales Tax

Hawaii's GET is fundamentally different from a traditional sales tax. It is a privilege tax on the business's gross receipts — not a tax added to the consumer's purchase price. However, businesses routinely pass GET through to customers. Because GET is calculated on total gross receipts (including the GET pass-through amount itself), the effective consumer rate is higher than the headline rate.

The Tax-on-Tax Formula (Oahu 4.5%)

GET Rate: 4.5% (Oahu) | Retail
GET owed = Gross Receipts × 4.5%
If passing through: charge customer = Pre-GET price ÷ (1 − 0.045)
Effective consumer rate = 4.5% ÷ (1 − 0.045) ≈ 4.712%

Wholesale rate: 0.5% (sales to licensed resellers)

Example: $10,000 sale on Oahu (4.5%)

Revenue: $10,000 | Oahu retail | Pass-through: yes
Pass-through amount: $10,000 ÷ (1 − 0.045) = $10,471
GET owed: $10,471 × 4.5% = $471
Business nets: $10,471 − $471 = $10,000 ✓
Customer pays $10,471 | Effective rate: 4.712%

Frequently Asked Questions

What is Hawaii's General Excise Tax and how is it different from a sales tax?
Hawaii's General Excise Tax (GET) is a tax on the gross receipts of businesses — not a consumer sales tax. It is imposed on the seller, not the buyer, and applies at every level of the supply chain (unlike a retail sales tax which typically applies only at the final sale). Because GET taxes gross receipts (including the pass-through of GET itself), it creates a compounding effect. The effective rate on consumers is slightly higher than the headline rate: about 4.166% statewide and approximately 4.712% on Oahu (with the 0.5% county surcharge).
What are the Hawaii GET rates by island/county in 2026?
Hawaii GET rates vary by county: City and County of Honolulu (Oahu) — 4.5% (4% state + 0.5% county surcharge); Kauai County — 4.5% (4% state + 0.5% county surcharge effective January 2023); Hawaii County (Big Island) — 4.25% (4% state + 0.25% county surcharge); Maui County — 4% (no county surcharge). The Big Island surcharge may change — always verify with the Hawaii Department of Taxation (DOTAX).
What is the wholesale GET rate in Hawaii?
Wholesale sales (sales to licensed retailers who then resell to consumers) are subject to GET at only 0.5% rather than the full 4%–4.5% retail rate. This is a significant reduction. However, if the retailer then sells to the consumer, the retailer pays full GET on their gross receipts (which include the wholesale price plus markup). The 0.5% wholesale rate prevents compounding at the wholesale level but does not eliminate GET entirely from the supply chain.
Can Hawaii businesses pass GET through to customers?
Yes. Hawaii law allows businesses to visibly pass the GET through to customers as a separate line item, similar to how mainland businesses add sales tax. When the pass-through is visible, the business charges the customer enough to cover the GET — since GET is calculated on gross receipts INCLUDING the amount passed through, a mathematical gross-up is required. For Oahu (4.5%), the pass-through amount is approximately 4.712% of the pre-GET price to net exactly the GET owed (due to the tax-on-tax nature).
What businesses are exempt from Hawaii GET?
Certain activities are exempt from GET: sales to the federal government; export sales; activities by nonprofit organizations (under strict conditions); insurance proceeds; and some agricultural production activities. Additionally, certain deductions are available, such as the wholesale deduction (0.5% instead of 4%), subcontractor deductions (preventing triple taxation in construction), and the inter-island transportation exemption. GET exemptions are narrower than typical sales tax exemptions — most economic activity in Hawaii is subject to GET.
