Small Business Health Insurance in Hawaii 2026: PHCA, HMSA, and Group Plans
Hawaii is the only state in the United States with a pre-ACA employer health insurance mandate. The Hawaii Prepaid Health Care Act of 1974 requires employers to provide health coverage to employees working 20 or more hours per week, well below the ACA’s 30-hour federal standard. For small business health insurance Hawaii employers, PHCA compliance is not optional and applies to businesses of any size. This guide explains the law, which carriers offer small business health insurance in Hawaii, and how ACA tools like SHOP and ICHRA interact with PHCA obligations. For a full overview of the Hawaii market, see the Hawaii health insurance guide.

The Hawaii Prepaid Health Care Act (PHCA) of 1974 requires all Hawaii employers to provide health insurance to employees who work 20 or more hours per week for four consecutive weeks. Employers must pay at least 50% of the monthly premium. The law applies to businesses of any size and is enforced by the Hawaii Department of Labor and Industrial Relations.
The PHCA’s 20-hour threshold is the most important distinction from federal law. Under the ACA, employers with 50 or more full-time equivalent employees must offer coverage to employees working 30 or more hours per week. The PHCA applies to all Hawaii employers regardless of size — a restaurant with two employees each working 22 hours per week must provide PHCA-compliant coverage. This makes small business health insurance in Hawaii obligations broader and more immediate than the ACA alone would require.
According to the Hawaii Department of Labor and Industrial Relations, the PHCA has been in effect since July 1, 1975, making Hawaii the only state with a pre-ACA employer mandate. The law is grandfathered from the ACA’s employer shared responsibility provisions, meaning Hawaii employers operate under PHCA rules rather than the ACA’s employer mandate for employees working 20–29 hours per week.
PHCA Key Requirements for 2026
Cover employees working 20+ hours/week for 4+ consecutive weeks. Pay at least 50% of the monthly premium. Coverage must meet minimum benefit standards set by the Hawaii Department of Labor. Employees working fewer than 20 hours/week or in their first 4 weeks of employment are not covered by PHCA, but may be offered coverage voluntarily.

SHOP Marketplace and Tax Credits for Hawaii Small Businesses
Hawaii small business health insurance employers with fewer than 25 full-time equivalent employees may qualify for the Small Business Health Care Tax Credit through the ACA’s SHOP marketplace. The credit covers up to 50% of premiums paid for qualifying small employers, but only if coverage is purchased through SHOP. Hawaii employers using SHOP can offer HMSA or Kaiser plans through HealthCare.gov’s small business portal.
| Business Size | PHCA Obligation | SHOP Tax Credit Eligible | Recommended Approach |
|---|---|---|---|
| 1–10 employees | Yes, if any work 20+ hrs/wk | Yes; up to 50% credit if avg wages below $56,000 | SHOP for tax credit; HMSA or Kaiser |
| 11–24 employees | Yes | Yes; partial credit (phases out) | Compare SHOP credit vs. direct group plan cost |
| 25–49 employees | Yes | No; above SHOP credit threshold | Direct group plan: HMSA, Kaiser, UHA, or HMAA |
| 50+ employees | Yes; PHCA and ACA mandate both apply | No | Direct group plan; consult agent for ACA compliance |
SHOP Tax Credit Requirement
The Small Business Health Care Tax Credit is only available when coverage is purchased through HealthCare.gov SHOP. Hawaii employers buying group coverage directly from HMSA or Kaiser do not qualify for the federal tax credit, even if they otherwise meet the criteria. Employers within the credit-eligible range should compare SHOP vs. direct carrier costs before enrolling. For a full breakdown of small business health insurance Hawaii tax credit eligibility, see the IRS guide linked above. The IRS SHOP tax credit guide covers eligibility rules and calculation methods in detail.

PHCA Compliance Steps for Hawaii Small Businesses
Hawaii small businesses must select a PHCA-compliant health plan, enroll eligible employees (those working 20+ hours for four consecutive weeks), and pay at least 50% of the monthly premium. New employees become eligible after four consecutive weeks at 20+ hours per week. Employers must notify employees of their rights under the PHCA and maintain records for DLIR audits.
Identify PHCA-eligible employees
Any employee who works 20 or more hours per week for four consecutive weeks becomes PHCA-eligible. Track hours carefully; Hawaii’s 20-hour threshold captures many part-time workers in the state’s large hospitality and tourism industry. Seasonal workers who hit the threshold must also be offered coverage.
Select a PHCA-compliant health plan
Choose a group health plan that meets PHCA minimum benefit requirements from an approved carrier: HMSA, Kaiser (Oahu), UHA, or HMAA. The plan must include basic hospitalization, surgical care, and outpatient services. A licensed agent can verify PHCA compliance for a specific plan before enrollment. This step is essential for any Hawaii small business health insurance arrangement.
Pay at least 50% of the premium
PHCA requires employers to contribute at least 50% of the monthly premium for employee-only coverage. Employer contributions are fully deductible as a business expense under federal tax law. Employee premium contributions are made pre-tax through a Section 125 cafeteria plan, reducing payroll tax liability for both employer and employee.
File PHCA documentation with DLIR
Hawaii employers must maintain records of PHCA-eligible employees and coverage offered. The Hawaii DLIR may audit PHCA compliance, particularly for employers in Hawaii’s hospitality sector where seasonal and variable-hour employment is common. Licensed agents assist with PHCA documentation requirements at no additional cost.
Real Scenario: Kauai Restaurant, 8 Employees, 5 Working 25 Hours Per Week
A Kauai restaurant owner has 8 total employees: 3 full-time (40 hrs/week) and 5 part-time at 25 hours per week. All 8 are PHCA-eligible under the 20-hour threshold. Kaiser Permanente is not available on Kauai, so HMSA is the primary option for small business health insurance in Hawaii on the neighbor islands. With 8 employees, the business is SHOP-eligible for the Small Business Health Care Tax Credit. If average employee wages are below $56,000, the owner could receive a federal tax credit covering up to 50% of premiums paid through SHOP — reducing the annual insurance cost significantly. A licensed agent can calculate the SHOP credit vs. direct HMSA group plan pricing to identify the lower total cost.
ICHRA and QSEHRA: Alternatives to Traditional Group Plans
Small business health insurance Hawaii employers that find traditional group plans cost-prohibitive can use Individual Coverage HRAs (ICHRA) or Qualified Small Employer HRAs (QSEHRA) as PHCA-compliant alternatives. Under these arrangements, the employer reimburses employees for individual market plan premiums; employees choose their own HMSA or Kaiser plan and the employer manages a fixed monthly contribution. ICHRA has no size limit; QSEHRA is for employers with fewer than 50 full-time employees.
ICHRA: Individual Coverage HRA
Employer sets a monthly reimbursement amount (any amount). Employees purchase their own individual HMSA or Kaiser plan on or off exchange and submit for reimbursement. No size limit; works for any Hawaii employer. Employees cannot receive ICHRA reimbursements and marketplace subsidies simultaneously. Best for employers with varied workforce needs across multiple islands.
QSEHRA: Qualified Small Employer HRA
For Hawaii employers with fewer than 50 full-time employees. 2026 contribution limits: up to $6,350/year for employee-only coverage; $12,800/year for family coverage. Employees purchase individual HMSA or Kaiser plans and submit receipts. QSEHRA allowances reduce ACA marketplace subsidy eligibility dollar-for-dollar. Simpler administration than ICHRA for smaller employers. Employees needing individual coverage guidance can see the Hawaii individual health insurance guide.
Both ICHRA and QSEHRA can satisfy the small business health insurance Hawaii employer obligation under PHCA when structured correctly. The Department of Labor EBSA small business resources provide HRA compliance guidance. Hawaii-specific PHCA compliance with HRA arrangements should be verified with a licensed agent familiar with both PHCA and federal HRA regulations. For employees who purchase individual coverage through these arrangements, the Hawaii health insurance marketplace guide covers enrollment and subsidy interaction. Employees with incomes that may qualify for Med-QUEST should also review the affordable health insurance guide for Hawaii.
Frequently Asked Questions — Small Business Health Insurance in Hawaii
The most common questions about small business health insurance in Hawaii involve PHCA coverage thresholds, which carriers are available by island, how the SHOP tax credit works, and whether ICHRA or QSEHRA can satisfy the employer mandate.
Is health insurance required for small businesses in Hawaii?
Yes. The Hawaii Prepaid Health Care Act of 1974 requires all Hawaii employers, regardless of business size, to provide health insurance to employees who work 20 or more hours per week for four consecutive weeks. Employers must pay at least 50% of the monthly premium. The obligation applies to businesses with even one eligible employee, making small business health insurance Hawaii obligations broader than the federal ACA 50-employee threshold.
What carriers offer small business health insurance in Hawaii?
Hawaii small business employers can choose from four primary group carriers for 2026: HMSA (available on all six major islands, PPO and HMO), Kaiser Permanente Hawaii (Oahu only, HMO), UHA (statewide, group plans), and HMAA (association-based group plans, primarily Oahu). HMSA is the most widely used carrier for small business health insurance in Hawaii across all islands. On neighbor islands, employers are limited to HMSA, UHA, and HMAA. For help comparing all small business health insurance Hawaii options by island, a licensed agent can provide a no-cost comparison.
What is the SHOP marketplace and does it apply to Hawaii?
The SHOP (Small Business Health Options Program) marketplace at HealthCare.gov allows Hawaii employers with fewer than 50 full-time equivalent employees to offer HMSA or Kaiser health plans to their employees and potentially qualify for the Small Business Health Care Tax Credit. The credit covers up to 50% of premiums for employers with fewer than 25 FTE employees earning average wages below $56,000. Employers must purchase coverage through SHOP to claim the credit. SHOP enrollment is available year-round for qualifying Hawaii employers.
How does the PHCA interact with the ACA employer mandate?
Hawaii is grandfathered from the ACA’s employer shared responsibility provisions for employees working 20–29 hours per week. This means Hawaii employers operate under PHCA rules for those employees rather than the ACA’s 30-hour threshold. For employees working 30 or more hours per week, both PHCA and ACA requirements apply, though PHCA’s 50% minimum premium contribution is the key standard in practice. Hawaii businesses with 50 or more full-time equivalent employees must also comply with ACA reporting requirements regardless of PHCA coverage.
Can I use an ICHRA or QSEHRA instead of a group plan in Hawaii?
Yes. Hawaii employers can use an Individual Coverage HRA (ICHRA) or Qualified Small Employer HRA (QSEHRA) as an alternative to a traditional group plan, provided the arrangement satisfies the PHCA’s 50% minimum contribution requirement. Under ICHRA, the employer reimburses employees for individual HMSA or Kaiser plan premiums with no contribution limit. Under QSEHRA, employers with fewer than 50 full-time employees can contribute up to $6,350/year (employee-only) or $12,800/year (family) in 2026. PHCA compliance with HRA arrangements should be reviewed with a licensed agent familiar with Hawaii law.
