Hawaii Paycheck Tax Calculator: How Hawaii Withholding Works
A Hawaii paycheck calculator has more to get right
than most: a progressive withholding schedule, HW-4 allowances and a
possible TDI share. On your pay stub, the income tax usually appears
as SIT or HI state withholding
and TDI as its own line; our
pay stub abbreviations list
explains the other codes.
Federal Withholding for Hawaii Paychecks
Federal withholding uses your Form W-4 and the 2026 IRS Publication
15-T tables. The calculator supports filing status, Step 2(c), Step 3
credits and Step 4(a), 4(b) and 4(c). If you claim the new overtime
or tips deductions, our
W-4 Step 4(b) worksheet guide
shows how to enter them, and our
2026 federal tax withholding guide
covers the rest.
Prepaid Health Care
Hawaii's Prepaid Health Care Act requires employers to offer health
coverage to employees who work at least 20 hours a week for four
weeks in a row. The employer pays at least half the premium, and
your share can't exceed 1.5% of your gross wages. If it's taken
pre-tax through a cafeteria plan, enter it in the Section 125 field.
Nonresidents and Military Spouses
Hawaii taxes wages earned for work done in Hawaii, whether or not
you live there, and it has no reciprocal agreements with other
states. Qualifying nonresident military spouses can be exempt from
Hawaii withholding; pick the matching option in the calculator's
withholding exception field.
No Local Income Tax
No Hawaii county taxes wages. Honolulu, Maui, Hawaii County and
Kauai add nothing to paycheck deductions. The general excise tax
(GET) is charged on sales, not withheld from pay.
Bonuses
Bonuses are subject to Hawaii withholding along with federal
withholding (usually a flat 22% on separately paid bonuses) and
FICA. See why bonuses are taxed so high.
Employer Payroll Costs in Hawaii
Employers pay state unemployment tax
on the first $64,500 of each employee's wages in 2026, under rate
schedule C with a 2.4% rate for new employers. They also pay at
least half the TDI premium, their share of Social Security and
Medicare and federal unemployment tax. At year-end, our
W-2 form generator
can use the same wage and withholding totals.
Why Your Actual Hawaii Paycheck May Differ
This calculator is a close estimate, not your employer's payroll
run. Your HW-4 on file, your employer's TDI and health plan
contributions, benefit elections, year-to-date wages and a 27th
biweekly payday in some years can all move the result a little.
Three-paycheck months
change monthly cash flow but not the tax on each check. For a full
checklist, see why your paycheck is lower than expected.
