Payroll costs the state adds

What Hawaii charges an employer on top of wages: unemployment tax, and any paid-leave or disability program funded through payroll, and who must carry workers’ comp. Federal Social Security, Medicare and unemployment tax apply in every state and are already in the calculator. Workers’ comp premiums depend on the class code and the insurer, so the card gives the rules, not a rate.

Workers’ compensation

Hawaii Department of Labor and Industrial Relations, Disability Compensation Division

Who must carry it
Any employeeAny employer with one or more employees, full-time or part-time, permanent or temporary, must provide workers’ compensation coverage, except those excluded by HRS § 386-1. labor.hawaii.gov
Where to buy it
Private insurersMost employers buy from insurance carriers authorized to write workers’ compensation in Hawaii (the Department of Commerce and Consumer Affairs keeps the list); the alternative is director-approved self-insurance. Employees may not be made to pay toward premiums. labor.hawaii.gov
Owners
Excluded from covered employment are sole proprietors, partners, LLC members with at least a 50% interest, anyone owning at least 50% of the corporation they work for, and unpaid officers owning at least 25% of a corporation with no employees (HRS § 386-1). No employer may require a worker to incorporate, form an LLC or become a partner as a condition of employment. capitol.hawaii.gov
Construction
A contractor who takes on work under a contract is the employer of everyone doing that work, including the employees of its subcontractors and their subcontractors (HRS § 386-1). capitol.hawaii.gov

Employer pays
The cost not withheld from employees (at least half of the premium); amount depends on the insurer premium
Wage cap
$1,500.21 a week per employee (the maximum weekly wage base)

New-employer rates usually last one to three years — longer in some states (four years in Indiana, four to five in D.C.); then the state assigns your own rate, and your rate notice wins over any figure here. The calculator below uses the new-employer rate where one is clear. Where a state’s own pages could not be read, the card says so and gives the U.S. Labor Department’s figure.

Sales tax on your work

What Hawaii’s tax agency says about repair and installation labor on buildings and the parts and fixtures that go into them. This is what the agency’s pages say, not tax advice.

Labor
TaxedHawaii has no sales tax, but its general excise tax (GET) applies to a contractor’s gross income from building, repairing or improving structures: 4% plus the county surcharge. Businesses may pass it on to customers.No repair vs. new construction split. Qualifying payments to subcontractors can be deducted from gross income; the cost of materials can’t.
Materials
Customer, in the price or on the billMaterials are part of the contract price taxed at 4% plus surcharge, which the contractor may pass on to the customer; the supplier’s sale of materials built into the job is a wholesale sale taxed at 0.5%.
Also
Each county adds a 0.5% surcharge, in effect through 2030.

Licenses and state fees

The license a shop needs from the state to contract for each trade, the board that issues it and the fees on its own schedule. Cities and counties can add their own licenses, registrations and permit fees; exam vendors and fingerprinting may charge more.

Plumbing, HVAC and Electrical

State license

Hawaii Contractors License Board (Department of Commerce and Consumer Affairs, Professional and Vocational Licensing Division)

  • Plumbing C-37 Plumbing contractor
  • HVAC C-52 Ventilating and air conditioning contractor
  • Electrical C-13 Electrical contractor

Generally, anyone who offers to, holds oneself out as able to, or contracts to perform residential, commercial, or public works construction, alterations, or improvements must hold a contractor license.

FeeAmount
Application fee (non-refundable)one-time$50
Examination feeone-time (per exam part; most classifications have two parts)$75
Initial license feescontracting entity or sole proprietor, licensed Oct 1 of an even year – Sept 30 of an odd year (license fee $355 + recovery fund $150 + education fund $10 + compliance resolution fund $148)one-time (license runs to Sept 30 of the next even year)$663

Biennial renewalcontracting entity and sole proprietor (total)2 years$353

Initial totals are from the Board’s FAQ and match HAR 16-53-17: $663 = license fee $355 (original $260 plus half the $190 renewal) + recovery fund $150 + education fund $10 + compliance resolution fund $148; $494 = $260 + $150 + $10 + $74. Renewal $353 = $190 + education fund $5 + recovery fund $10 + compliance resolution fund $148. All licenses expire Sept 30 of even-numbered years. An entity also needs a licensed Responsible Managing Employee (RME), who pays separate fees (RME license fees $438 or $334 depending on the year of the biennium; renewal $208).

Plumbing Plumbing work itself must be done by an individual licensed as a plumber (PM or PJ) by the Board of Electricians and Plumbers (HRS 444-9.5, ch. 448E) — separate license not covered here.

Electrical Electrical work itself must be done by an individual licensed as an electrician (ES or EJ) by the Board of Electricians and Plumbers (HRS 444-9.5, ch. 448E) — separate license not covered here.

Keeping the license

Renewal
PlumbingHawaii contractor licenses, including C-37 plumbing, all expire September 30 of even-numbered years and renew every two years; individual journeyman and master plumber licenses renew every three years by June 30 (2027, 2030, 2033). cca.hawaii.govHVACHawaii contractor licenses, including C-52 ventilating and air conditioning, all expire September 30 of even-numbered years and renew every two years. cca.hawaii.govElectricalHawaii contractor licenses, including C-13 electrical, expire September 30 of even-numbered years and renew every two years; individual electrician licenses renew every three years by June 30 (2026, 2029, 2032). cca.hawaii.gov
Continuing ed.
PlumbingThe contractor license itself has no continuing-education rule, but active journeyman and master plumbers must complete the Board of Electricians and Plumbers’ continuing competency course on the 2021 Uniform Plumbing Code to renew for the July 1, 2024 to June 30, 2027 period; the board names the course, not a number of hours. cca.hawaii.govHVACThe Contractors License Board’s renewal requirements (fees, tax clearance, insurance and any bond) include no continuing education for contractor licenses. cca.hawaii.govElectricalThe contractor license has no continuing-education rule, but active licensed electricians (except maintenance electricians) must complete the Board of Electricians and Plumbers’ continuing competency course on National Electrical Code updates to renew; the board names the course, not a number of hours. cca.hawaii.gov
Reciprocity
The Hawaii Contractors License Board has no reciprocity agreements; every applicant must meet the same licensing and exam requirements. cca.hawaii.gov

Beyond the trade license

Contractor registration, bond and insurance the state asks of a trade shop

Registration
In Hawaii the specialty contractor license from the Contractors License Board (for example C-37 plumbing, C-13 electrical, C-52 ventilating and air conditioning) is the contractor license itself; there is no extra statewide contractor registration on top of it. Individual electricians and plumbers also need their own licenses from the Board of Electricians and Plumbers. cca.hawaii.gov
Bond
The Hawaii Contractors License Board has no standard bond amount, but it may require a surety bond as proof of financial integrity before issuing a license, and any bond it imposes must be kept current at renewal (HAR 16-77). cca.hawaii.gov
Insurance
$300,000Hawaii contractors must carry liability insurance of at least $100,000 per person and $300,000 per occurrence for bodily injury and $50,000 per occurrence for property damage, plus workers’ compensation if they have employees, and keep the coverage continuous; a lapse forfeits the license (HAR 16-77-8). cca.hawaii.gov

State or city license?

State license only Who licenses the trades in Hawaii

Contractor licenses and individual electrician and plumber licenses are issued by the state (DCCA’s Contractors License Board and Board of Electricians and Plumbers); the counties issue building, electrical and plumbing permits and register owner-builders. cca.hawaii.gov

State and city pages read

What Hawaii law says about lien rights on private jobs — the notices, the deadline to file and the deadline to sue — and whether a statute sets payment deadlines or caps retainage. Read from the statute itself; it is not legal advice.

Mechanic’s lien

Haw. Rev. Stat. §§ 507-41 to 507-49Chapter 507, Part II. Mechanic’s and Materialman’s Lien

You, hired by the owner
Before or when a homeowner signs a contract for home construction or improvements, a licensed contractor must explain verbally all lien rights of everyone on the job and the homeowner’s option to demand a bond, and must give a written signed contract containing that information before work starts (HRS § 444-25.5). A violation is an unfair or deceptive practice under chapter 480. There is no pre-lien notice on non-residential jobs. capitol.hawaii.gov
Subs and suppliers
No preliminary noticeHawaii’s lien part has no preliminary notice for subcontractors or suppliers; every claimant files the same Application for a Lien with the circuit court and serves the owner, the general contractor and the party who contracted for the work (HRS § 507-43(a)). capitol.hawaii.gov
File the lien
45 daysFile the Application for a Lien and Notice of Lien in circuit court no later than 45 days after the date of completion, which is when a notice of completion has been published twice and filed with the court clerk; if no notice is published within one year, completion is deemed to be one year after actual completion (HRS § 507-43(b), (f), (g)). The lien attaches only after a court hearing finds probable cause. Subs and suppliers have the same deadline. capitol.hawaii.gov
Enforce it
3 monthsThe lien expires 3 months after the court enters the Order Directing Lien to Attach unless you start proceedings to enforce it within that time (HRS § 507-43(e)); the foreclosure action is filed in the circuit court where the property is (§ 507-47). capitol.hawaii.gov
Homes
On repairs or improvements to property used mainly as a dwelling, a supplier has no lien for materials sold to a general contractor or sub who was required to be licensed but was not, or if it gave the contractor unreasonable credit; a credit application or reasonable credit inquiry makes the credit prima facie reasonable (HRS § 507-49(a)). capitol.hawaii.gov

Statutes read

Payment deadlines and retainage

Private jobs (public contracts have their own rules)

Prompt payment
Statute sets deadlinesOn private jobs a contractor must pay its sub within 10 days after the later of receiving the sub’s invoice with required supporting documents or being paid by the owner for that work, with interest at 1.5% per month from the due date unless there is a bona fide dispute (HRS § 444-25, which does not apply to public contracts). Section 444-25 sets no deadline for the owner to pay the prime contractor. capitol.hawaii.gov
Retainage
No private-job capHawaii sets no retainage cap or release deadline for private jobs; the lien part only lets the owner hold back from the contractor enough to cover filed liens (HRS § 507-48). capitol.hawaii.gov

There is no heating season at Honolulu airport: the normals show no heating degree days at all and 4,767 cooling degree days a year, with the most in August.

The lightest months for heating and cooling together are January and February (268 and 246 degree days).

The normals show no nights at or below freezing. Days reaching 90 °F: about 32 a year, the most in August.

NOAA’s population-weighted state figures cover only the 48 contiguous states, so Hawaii is shown by this station alone.
