Hawaii Contractor Tax Obligations and GET Requirements

Hawaii imposes a general excise tax (GET) on virtually all business activity conducted within the state, and contractors operating in Hawaii face a distinct set of tax obligations that differ meaningfully from sales tax regimes found in most other states. This page covers the structure of GET as it applies to contractors, how the tax is calculated and passed on, the classification distinctions that affect rates, and the compliance boundaries that define contractor liability. Understanding these obligations is essential context for any licensed contractor operating under Hawaii contractor license requirements.

Definition and scope

The general excise tax is a privilege tax imposed on the gross income of businesses operating in Hawaii, administered by the Hawaii Department of Taxation under Hawaii Revised Statutes (HRS) Chapter 237. Unlike a retail sales tax, GET is levied on the business itself — not technically on the consumer — though businesses are permitted to visibly pass it on to customers.

For contractors, GET applies to gross receipts from all contracting work performed in Hawaii. This includes new construction, renovation, repair, installation, and specialty trade work. The scope is broad: both general contractors and specialty contractors bear GET liability on the revenue they receive. Contractors who are also employers carry separate obligations under the Hawaii state income tax withholding system and federal payroll tax frameworks, but those are distinct from the GET filing structure.

Scope and coverage limitations: This page addresses Hawaii state tax obligations only. Federal income tax, federal self-employment tax, and IRS reporting requirements fall outside the scope of Hawaii state GET compliance and are not covered here. County-level taxes in Hawaii are limited to real property tax and do not impose additional GET-type levies on contractor income. Contractors performing work outside Hawaii — including those holding an out-of-state contractor license while temporarily working in-state — are subject to GET on income sourced to Hawaii only.

How it works

The standard GET rate for most contracting activity is 4% of gross receipts at the state level (Hawaii Department of Taxation, GET Overview). An additional county surcharge of 0.5% applies in Honolulu County (Oahu), bringing the effective rate to 4.712% when the GET is visibly passed on using the permitted surcharge formula. Maui County, Hawaii County, and Kauai County do not currently impose the surcharge, leaving those areas at the base 4% rate.

Contractors are permitted — but not required — to pass GET costs on to customers as a line item. When contractors choose to pass the tax on, the Hawaii Department of Taxation authorizes a specific markup formula rather than a simple percentage addition. For the 4% rate, the permitted pass-on amount is 4.166% of the contract amount. For the 4.5% combined rate (Oahu), the permitted amount is 4.712%.

GET filing structure for contractors:

  1. Registration: Contractors must register with the Hawaii Department of Taxation before conducting business. Registration is completed via Form BB-1 (Basic Business Application).
  2. Filing frequency: Determined by annual tax liability. Businesses with GET liability over $4,000 per year file monthly; those between $2,000 and $4,000 file quarterly; those under $2,000 file semiannually (Hawaii Department of Taxation, Filing Deadlines).
  3. Gross receipts basis: GET is calculated on total gross receipts — deductions for labor costs, materials, or subcontractor payments are generally not available unless a specific exemption applies.
  4. Subcontractor deduction: A licensed general contractor paying a licensed subcontractor may deduct those payments from gross receipts before calculating GET, provided the subcontractor is separately registered and paying GET on those same amounts. This prevents double taxation on the same revenue.
  5. Payment: Filed electronically through the Hawaii Tax Online portal maintained by the Department of Taxation.

The subcontractor deduction is a critical distinction for Hawaii contractor subcontractor relationships and requires that subcontractors hold active GET registrations.

Common scenarios

General contractor billing a property owner: The GC reports the full contract amount as gross receipts. If the GC paid licensed subcontractors, those payments are deductible. The remaining net amount is subject to GET at the applicable county rate.

Specialty contractor working directly for a property owner: A licensed roofing, electrical, or plumbing contractor billing the end client directly reports the full invoice amount as GET-eligible gross receipts. There is no deduction for materials. Contractors in these trades — including those covered under Hawaii roofing contractor services, Hawaii electrical contractor services, and Hawaii plumbing contractor services — operate under the same GET structure.

Solar installation contractors: Solar work qualifies for a state income tax credit under HRS Chapter 235, but GET liability on contracting revenue applies regardless of the tax credit. Contractors in this space, detailed further at Hawaii solar contractor services, must still register and remit GET on gross contracting receipts.

Public works contractors: Contractors on state or county public works projects are subject to GET. There is no blanket exemption for government contracts. Additional compliance requirements for this category are addressed at Hawaii public works contractor requirements.

Decision boundaries

GET vs. federal tax obligations: GET is a state privilege tax and runs parallel to — not in lieu of — federal income tax, self-employment tax, and payroll obligations. A contractor's GET filing does not satisfy or reduce federal tax liability.

Licensed vs. unlicensed status: GET registration and contractor licensing are separate regulatory tracks. The Hawaii DCCA Contractors License Board administers licensing; the Hawaii Department of Taxation administers GET. A contractor can be GET-registered without being licensed, or licensed without being GET-registered — both are independently required. Operating without a license has consequences addressed at Hawaii contractor registration vs. licensing.

Incorporated vs. sole proprietor: Both entity types are subject to GET. The business entity structure affects income tax filing but does not change GET rate or applicability. The broader context of contractor pricing and how GET interacts with cost structures is covered at Hawaii contractor costs and pricing.

Out-of-county work: A contractor based on Oahu performing work on Maui is subject to GET at the rate applicable to the county where the work is performed — Maui's 4% rate, not Oahu's 4.5% combined rate. This geographic distinction matters for multi-island contractors and connects to Hawaii county-specific contractor rules.
