How does Hawaii state income tax and unemployment insurance work in 2026?

How Hawaii compares to the rest of the United States

Only California and New York are in the same range as Hawaii on top marginal rate, and Hawaii is the only one of those three with the rate hitting at $325,000 single income. California's 13.3 percent peaks above $1,000,000. New York's 10.9 percent peaks above $25,000,000.

For a $250,000 Hawaii compensation package, state income tax alone runs to roughly $19,000 versus zero in Florida, Nevada, or Texas. The Hawaii premium for a senior earner is around 7 to 8 percent of gross salary in state income tax alone, before TDI and the Prepaid Health Care Act layered cost.

What this means for offer letters

Kai's $200,000 Honolulu offer carries roughly $15,400 in annual Hawaii income tax. The same offer in Texas or Florida costs zero state tax. Leilani is a Maui sales lead at $325,000. Her offer crosses into the 11 percent top bracket. Above that line, every additional dollar of base or bonus is taxed at the highest rate in the western United States.

Bake the full Hawaii ladder into your offer-letter take-home calculator before the first 2026 hire, and remember that Acts 46 and 47 of 2024 keep widening the brackets through 2031, so the gross-to-net you model in 2026 is not the gross-to-net you should model in 2028.

Why Q1 cash matters for a Hawaii payroll

Most low-wage-base US states clear their annual UI bill inside January for a typical full-time hire. Hawaii does not. At $64,500, the wage base spreads across most of the year for a $90,000 hire, so UI lines drip onto every paycheque until late September.

Makoa runs a Hilo operations team of eight people earning between $80,000 and $150,000. His combined 2026 UI bill at the new-employer rate is roughly $12,400 plus $52 in E&T assessment. The amount is split across the calendar year rather than concentrated in Q1, which is the opposite of how California payroll behaves.

How FUTA interacts

Federal Unemployment Tax (FUTA) is 6.0 percent on the first $7,000. A Hawaii employer that pays state UI in full and on time receives a FUTA credit of 5.4 percent, leaving an effective FUTA of 0.6 percent ($42 per employee per year). Hawaii's UI Trust Fund has been positive through the 2020s, so the state has not been subject to FUTA credit reduction in recent years. Verify via IRS Schedule A (Form 940) each January.

How the premium split works in practice

Hawaii TDI is one of the more complex premium-split mechanics in US payroll. The statute caps the employee share at 0.5 percent of weekly wages OR $7.50, whichever is less, and the employer pays the remainder. If the carrier premium is below 1 percent of wages, the rule lets the employer and employee share equally. Above 1 percent of wages, the employer carries the excess.

Kai earns $200,000 at a Honolulu tech company. His weekly wage of $3,846 is above the $1,500.21 cap, so his deduction is the flat $7.50 every week, $390 across the year. The employer pays the rest of the carrier premium, which for a typical small-employer policy runs to roughly the same dollar amount, putting the total per-head TDI cost at roughly $750 a year.

What TDI actually pays out

TDI funds short-term wage replacement for non-work-related illness or injury. Work-related injury goes to workers' compensation, a separate scheme under Haw. Rev. Stat. ch. 386. The benefit is 58 percent of average weekly wages up to the $871 maximum for 2026, payable after a 7-day waiting period for up to 26 weeks per disability.

Pregnancy is covered when it causes inability to work. Hawaii does not run a state Paid Family Leave programme alongside TDI. It is one of the states without state PFL, unlike California (PFL alongside SDI) or Connecticut (PFMLA).

Carrier or state plan

The default for most Hawaii employers is to buy an approved private TDI policy from a carrier like MetLife, Guardian, Prudential, or HEMIC. Large employers can self-insure with state approval and a posted bond. The state plan is a backstop, mostly used by employers between carrier policies. The carrier handles claims; the state DCD audits compliance.

The 1.5 percent of gross earnings cap is the binding constraint

Leilani is a Maui sales lead earning $9,000 a month. Her PHC premium is $600 per month total. 50 percent of $600 is $300. 1.5 percent of $9,000 is $135. The lower of the two binds, so she pays $135 a month and the employer pays $465. The employer effective share is 77.5 percent, not the headline 50 percent.

For lower-paid employees the gap widens. A part-time front-desk employee earning $2,500 a month under a $500 premium has the 1.5 percent cap bind at $37.50. The employer pays $462.50, or 92.5 percent of the premium. PHC is the single most-underestimated line item on a Hawaii employer's cost model.

Why most mainland employers get the cost wrong

Mainland employers used to ACA-only obligations forget that PHC applies at a much lower threshold than the ACA employer mandate (which kicks in at 50 full-time-equivalents). PHC applies from the first qualifying employee. On a 30-person Hawaii workforce mixing full-time and part-time roles, the annual employer-paid PHC premium can run $150,000 to $300,000 depending on plan and household composition. That is a cost no other US state requires by statute.

PHC was enacted in 1974 and was specifically exempted from ERISA preemption by a 1983 federal amendment. ERISA does not override it. That is why the mandate has survived every legal challenge for half a century.

The HC-5 waiver is narrower than employers assume

An employee can waive PHC coverage on Form HC-5 only if they have qualifying alternative coverage through a spouse, parent, or other employer. Waiver is not optional for the employee just to avoid the payroll deduction. The employer must verify the alternative coverage and retain the HC-5 on file. Misuse of waivers is one of the more common audit findings in DLIR DCD compliance reviews.

The HW-4 captures four things:

• Filing status. Single, married, certified disabled person, or certain qualifying nonresident military spouse. Each maps to a different Hawaii withholding table.
• Number of allowances. Calculated on the worksheet, one allowance for the employee, one for the spouse if applicable, one per dependent claimed for Hawaii purposes. Each allowance reduces the wage base the table is applied to.
• Additional dollar amount per pay period. A flat-dollar over-withholding line for employees who want to over-pay to cover side income or capital gains.
• Exempt status. Available for employees who expect zero Hawaii income tax liability in the year.

Why the post-2020 federal W-4 doesn't satisfy Hawaii

The 2020 federal W-4 removed allowances and switched to a dollar-amount-of-deductions model. Hawaii kept the allowance model. An employee filing only the post-2020 federal W-4 leaves the employer with no allowance count for the Hawaii table, so the highest-rate default fires until the HW-4 lands in payroll.

That is the single most common over-withholding trap on a multi-state Hawaii payroll. Capture HW-4 alongside Form I-9 and federal W-4 on day one and the default never fires.

The HW-2 and HW-3 year-end pair

At year end, the employer issues a Form HW-2 (Hawaii's wage and tax statement, parallel to W-2) for every Hawaii employee. The employer files an annual Form HW-3 reconciliation by 28 February of the following year, with HW-2s attached. Effective 1 January 2026, employers filing 10 or more W-2 plus HW-2 forms must e-file regardless of withholding tax liability, under a Hawaii Department of Taxation rule change announced late 2025.

The 15th-of-month withholding deadline

Hawaii is unusual on income tax withholding cadence. Form HW-14 is due the 15th of the month after each quarter, not the last day. That is two weeks earlier than most US states. Multi-state payroll teams running a unified last-of-month quarterly close miss the Hawaii deadline by default and pick up a 5 percent late-filing penalty plus interest on the first quarter end.

Makoa runs a Hilo operations team and his payroll provider was on a 30 April first-quarter close cadence. The first Hawaii HW-14 was filed on 30 April, 15 days late. The penalty was 5 percent of withheld tax plus interest from the 15th. On a $40,000 first-quarter withholding total, that was $2,000 in penalty before interest. A single calendar override fixed the cadence going forward.

Hawaii Tax Online (HTO) and the DLIR portal

HW-14, HW-3, and HW-2 file through Hawaii Tax Online at hitax.hawaii.gov. UC-B6 files through the Hawaii Unemployment Insurance Division employer portal. TDI-15 and HC-4 file with DLIR DCD on paper or PDF upload, depending on the year's portal status. Hawaii has not unified the three regimes onto a single portal. Login, account number, and quarterly close are separate for each.

Zero-filing rule

An employer with no Hawaii wages for a quarter still files a zero HW-14 and a zero UC-B6. Skip the zero filing and Hawaii DOTAX and DLIR flag the missing return and start the delinquency clock. The zero filing is the cheapest possible compliance line and the one most often missed by employers between Hawaii hires.

The three-test reality

The same Hawaii worker can sit in three classification buckets depending on which state regime is asking. DLIR UI applies the ABC-style test for unemployment. DOTAX follows the IRS common-law test for income tax withholding. DLIR DCD applies a right-to-control test for workers' comp, TDI, and (by extension) PHC.

A worker correctly issued a 1099 for federal and Hawaii income tax purposes can still be an employee for UI under the ABC-style test, AND an employee for TDI under the right-to-control test. The misclassification audit can come from any of the three agencies independently.

The PHC liability tail

This is the most-missed exposure on a misclassification audit in Hawaii. If a worker is reclassified as an employee, AND they would have crossed the PHC 20-hour-per-week threshold during the misclassification period, the employer owes both the back PHC premium AND a penalty under Haw. Rev. Stat. ch. 393. The premium itself can run $400 to $700 a month per worker. On a multi-year misclassification of a single contractor working 20-plus hours a week, the back-PHC exposure alone can clear $30,000 before any UI or income tax assessment lands.

Action: classify upfront, audit annually

The safe default for a contractor engagement in Hawaii is to run the ABC-style test for UI alongside the IRS common-law test for income tax at the point of contracting, not on the back end of an audit. If either test indicates employee status, the safest call is to engage through an EOR rather than as a 1099. Teamed handles that analysis automatically and runs the full Hawaii payroll stack from day one, so the misclassification risk never sits on your books.

What a Hawaii hire through Teamed looks like operationally:

• Day 0. DOTAX withholding registration through Hawaii Tax Online, DLIR UI account through the employer portal, DLIR DCD registration for TDI and PHC, and the approved TDI carrier policy plus the approved PHC health insurance plan. Teamed US Inc. (Delaware) is the legal employer.
• Day 1. Employee onboarded with Form HW-4 (filing status and allowance count), federal W-4, and Form I-9 in a single digital signing session. PHC enrolment within four weeks for any employee on the 20-hour trigger.
• Ongoing. Hawaii income tax withheld and deposited on the cadence triggered by prior-year withholding history. TDI premium split between employer and employee with the $7.50/week employee cap enforced. UI on the $64,500 wage base, with the 0.01 percent E&T assessment layered. PHC premium remitted to the carrier monthly with the 1.5 percent of gross earnings employee-share cap enforced per pay period.
• Quarterly. HW-14 filed with DOTAX by the 15th of the month after quarter end. UC-B6 filed with DLIR UI by the last day of the month after quarter end. Both reconciled against the deposit history.
• Year end. Federal W-2 plus Hawaii HW-2 issued to every employee. HW-3 reconciliation filed with DOTAX by 28 February. TDI-15 filed with DLIR DCD by end of February. HC-4 PHC compliance statement filed with DLIR DCD by end of February. UI rate notice for the following year received from DLIR in December and applied to the first January payroll.

Pricing is one number per employee per month, in any currency you pay us in, with no FX mark-up between your billing currency and the US dollars Teamed remits to DOTAX and DLIR. Statutory employer cost (FICA, FUTA, UI, E&T assessment, employer half of TDI, PHC employer share, workers' compensation insurance) passes through at cost, itemised on every invoice and auditable line by line.

Behind the platform sits a named country specialist for the United States and an in-house payroll specialist who knows the Hawaii three-regime split, the HW-14 15th-of-month withholding cadence, the PHC 86.67-hour earnings trigger, the TDI premium split mechanic, and the ABC-style classification test that DLIR UI applies independently of DOTAX. When something looks off on a payslip, you message the same person. No support tickets. No chatbot triage.

Contractor onboarding, EOR payroll, and entity graduation all live on one platform. A Hawaii contractor who converts to W-2 keeps their record. That same employee can graduate from EOR to your own Hawaii-registered entity without changing system. Contractor through EOR to entity, one timeline, same system from first hire.

When EOR is the right call (and when it isn't)

EOR works while you're testing the Hawaii market, ramping a small remote team, or running one or two Hawaii hires alongside a larger US payroll elsewhere.

The compliance overhead is real: HW-14 on the 15th, UC-B6 on the last day, the PHC carrier relationship, the TDI premium split, the three-regime classification audit risk. The maths of running your own Hawaii entity starts to win earlier than in lighter-touch states because the three-regime ongoing overhead has a real cost, often around 10 to 15 Hawaii employees. Teamed's Crossover Calculator shows you the month it flips. We tell you when the model no longer fits and walk you through graduating to your own Hawaii-registered entity. That conversation is built into the relationship.
