Hawaii Paycheck Calculator

Five tax lines can come out of a Hawaii paycheck: federal income tax, Social Security (6.2% up to $184,500), Medicare (1.45%), Hawaii state income tax, and your share of temporary disability insurance (TDI). No county in Hawaii taxes wages. Prepaid Health Care premiums that many employers deduct are a benefit cost, so treat them like your other pre-tax elections such as 401(k) and HSA when you fill in the calculator.

Booklet A's annualized method multiplies your pay by the periods in a year, subtracts $1,144 for each allowance on your Form HW-4 plus a $4,350 lump-sum allowance, then runs the rest through the Single or Married schedule. Single starts at 1.4% on the first $9,600 and steps through 3.2%, 5.5%, 6.4%, 6.8%, 7.2%, and 7.6% to 7.9% above $125,000; Married doubles each threshold and reaches 7.9% above $250,000. Head of household uses the Single schedule. Enter your HW-4 allowances, dependents included, in the Hawaii exemptions field.

TDI is Hawaii's state disability premium. The employee share is capped at 0.5% of weekly wages on the first $1,500.21 a week, so at most $7.50 per week in 2026; the actual rate depends on your employer's plan, and 0.5% is the ceiling. This calculator models the ceiling, 0.5% of wages up to $78,010.92 a year, on the line labeled Hawaii temporary disability insurance. If your employer pays more of the premium, your real deduction is lower.

For 2026 the lump-sum allowance rose from $1,650 to $4,350, implementing the Act 46 standard deduction increase, which lowers Hawaii withholding on the same pay; the $1,144 per-allowance amount and the brackets are unchanged, with the next bracket shift scheduled for 2027. The TDI wage base rose from $1,441.72 to $1,500.21 a week. Bonuses are withheld under the aggregate method only, added to regular wages and run through the same schedule. Hawaii has no reciprocity agreements; with no HW-4 on file, employers withhold as single with zero allowances.
