Does Hawaii's general excise tax apply to work for the federal government?

The GET is not a sales tax, and the difference decides everything

Three features of the GET run against mainland instincts, and each matters on a federal job. First, the tax is on the business, measured by gross receipts, with no general exemption for costs or thin margins; a contractor is taxed on the top line, which makes the effective burden on a low-margin bid much larger than 4.5 percent of profit, and the burden compounds on a layered job, because the same construction dollar can be reached once at the prime level and again at the subcontractor level. Second, passing the tax on is a pricing decision, not a legal mechanism: businesses may visibly pass the GET to customers, up to a maximum of 4.712 percent to account for the tax on the passed-through tax itself, but nothing obligates the customer to pay it, and a federal customer whose contract declares the price tax-inclusive has already answered the question. The bid is the moment of truth: the GET belongs in the cost build-up like labor and fuel, at the pass-on rate if the pricing structure allows it, and a contractor who discovers the tax after award has no one to invoice. Third, immunity doctrines do not rescue the position. Because the incidence is on the seller, work for the federal government is taxable gross income unless a specific exemption applies, and the federal exemptions are narrow: sales of tangible personal property to the United States (Haw. Rev. Stat. section 237-25(a)(3)), shipbuilding and ship repair on federally owned surface vessels (section 237-28.1), and scientific work under a federal contract or subcontract (section 237-26), which leaves dredging, construction, and most other contracting receipts inside the base.

Hawaii's general answer to that pyramiding is a lower rate rather than an exemption: transactions at the intermediate level, goods and services sold to a licensed business that resells them, are taxed at the wholesale rate of 0.5 percent instead of the 4 percent retail rate, so a layer that adds no final value bears half a percent. Contracting gets its own mechanism, and it is the largest piece of relief available to a Hawaii prime contractor. Haw. Rev. Stat. section 237-13(3)(B) allows a contractor to deduct amounts that are included in the measure of the contracting tax on another taxpayer who is itself a contractor as defined in section 237-6, so the prime is taxed on the job net of the subcontracted portion while the subcontractor is taxed on what it received, and the work is reached once rather than twice. The deduction is conditioned rather than automatic: the payee has to be a contractor within the statutory definition, and the prime has to report the subcontractor's name and general excise number on its return, which makes the deduction a records discipline set up at award rather than a computation attempted at year end. On a federal job priced tax-inclusive, that discipline is the difference between bearing the tax on a margin and bearing it on money that was merely passed through.

The maritime exemptions, read precisely

Hawaii does carve real maritime activity out of the GET, and the carve-outs reward exact reading (Haw. Rev. Stat. section 237-24.3(3)). Exempt categories include amounts received from loading or unloading cargo from ships, barges, vessels, or aircraft, including stevedoring, whether or not the vessels travel interstate or between the islands; tugboat services including pilotage, and the towage of ships, barges, or vessels in and out of state harbors or from one pier to another; the transportation of pilots or government officials to vessels offshore, along with rigging gear, freight checking, standby charges, and mooring use; and wharfage and demurrage paid to the state transportation department. For a marine operator, the map this draws is specific: the towing side of the business, harbor towage, pier-to-pier movements, assist work, sits inside the exemption, while a dredging contract is contracting or service income that the exemption does not mention, and characterizing dredged material as "cargo" to pull excavation work into the cargo-handling exemption is the kind of argument that reads better in the field than it will in an assessment protest. The practical discipline for a mixed project is separation: where a project includes exempt towage alongside taxable dredging or construction, the contract and the invoices should state the exempt charges separately, supported by records distinguishing the activities, because an undifferentiated contract price is taxed as an undifferentiated contract price, and exemptions claimed by allocation after the fact carry the burden uphill. Exempt amounts are also still reported: the GET return discloses gross income and claims exemptions on schedule, so the exemption is a reporting position renewed every period, not a reason to stay off the rolls.

The use tax side: vessels, equipment, and ship stores

The companion levy is the use tax on property imported into Hawaii for use in the state, measured by landed value, the property's value on arrival including shipping, insurance, and duty (Haw. Admin. R. section 18-238-1), and it is the tax a mobilizing contractor worries about with a fleet steaming toward the islands. Two provisions do most of the protective work. Property imported for temporary use, with the intent that it not be kept permanently in the State, and in fact removed, is excluded from taxable use under the definition of use in Haw. Rev. Stat. section 238-1, and the statute's own illustrations include a contractor importing equipment to perform a construction contract with the intent to remove it, and removing it, at completion, which describes a project fleet. The statute itself states the test as intent plus actual removal, but the Department's rule adds a ceiling: temporary use does not include property located in or in use within the State for more than 365 days (Haw. Admin. R. section 18-238-2(g)(3)). The result is a two-part discipline. Equipment scheduled to stay longer than a year, such as the spread for a fourteen-month dredging contract, should be treated as outside the exclusion unless the position is taken deliberately against the rule. Equipment meant to stay permanently does not earn the exclusion by looking brief, because intent and removal remain conditions whatever the duration. Within the 365 days, the demobilization record, and not the project length alone, is what the position rests on. And goods imported by the owner of a vessel engaged in foreign or interstate commerce that are held and used solely as ship stores, the supplies required for operating and maintaining the vessel, are exempt. The documentation matching the exemptions is cheap and worth keeping deliberately: the project schedule and demobilization records that prove the temporary intent, and the segregation of ship-store purchases from project consumables, since consumables bought in Hawaii carry GET in their price while imported ones invite the use tax question. What the temporary-use exclusion does not do is answer the income tax: a project of any length still generates Hawaii gross receipts and Hawaii payroll for apportionment purposes, and the fleet's presence on the measuring dates can add a property factor, so the mobilization memo should cover the formula's three factors alongside the excise questions.

Registration, filing, and the mid-project scramble

The GET runs on registration and periodic self-assessment: register before the first Hawaii receipts, file the periodic return, monthly once the annual liability is more than modest, with the payment due by the twentieth of the following month, and reconcile annually on the year-end return. Federal agencies increasingly check, asking contractors mid-project for evidence of state tax registration and payment, and the contractor who registered at contract signing answers with an account number while the one who did not begins a scramble that plays out in front of the customer. Late registration is recoverable, the receipts were taxable from day one and the cure is registration plus back-filed periods with interest, but it is the sort of administrative noise that a one-hour registration at bid acceptance forecloses. Entity registration with the state's business registry is a separate question that government contracting typically forces anyway, and doing both together, with the exemption analysis and the use tax memo, is the whole mobilization package.

Practice notes

The Hawaii checklist for a mainland contractor fits on one page, and it is a bid-stage document, not a mobilization one: price the GET at the combined county rate, at the pass-on rate where the pricing structure permits and as an absorbed cost where the contract is tax-inclusive; register for the GET and the business registry at award; confirm that every subcontractor qualifies as a contractor under section 237-6, collect its general excise number, and set up the records the subcontract deduction requires before the first progress payment; structure and invoice exempt maritime services separately from taxable contracting; paper the temporary-use position for every imported hull and piece of equipment, with the demobilization plan documented from the start, the 365-day ceiling calendared, and the intent documented rather than inferred from the schedule; segregate ship stores; and set the apportionment tracking, receipts, project payroll, property presence on the measuring dates, before the first crew flies out. The recurring failure is not any single rule; it is sequencing, the contractor who prices without the tax, registers when asked, and reconstructs the exemptions at year end, each step costing money the bid-stage version of the same work would have kept.
