Hawaii Paycheck Calculator
Enter what you are paid before tax and how often, and see roughly what you take home in Hawaii. It shows federal income tax, Hawaii income tax withholding, Social Security and Medicare.
This is an unofficial estimate from published rules. Your employer's payroll system, your federal Form W-4 and your Hawaii Form HW-4 decide what is really withheld. The real tables are in Booklet A from the Hawaii Department of Taxation and in the tax tables from the IRS.

How it works
Your pay for the year is the paycheck times the number of paychecks. Pre-tax savings come off first. For federal tax, the 2026 standard deduction for your filing status comes off next, and the rest is taxed band by band with the 2026 federal brackets.
Hawaii withholding follows the annual method in Booklet A. From your yearly pay after pre-tax savings it subtracts a fixed amount for each allowance you claim and one extra withholding allowance, then taxes what is left band by band, with rates from 1.4% to 7.9%. Married workers use a wider set of bands. Both allowance amounts are inputs you can change. Social Security takes 6.2% of pay up to a yearly limit and Medicare takes 1.45%, with an extra 0.9% on pay above 200,000 in a year. Hawaii's temporary disability insurance, local taxes and credits are not included.
Worked example
A paycheck of $3,000.00 before tax, with $150.00 put into pre-tax savings and 1 allowance, comes to about $2,175.22 after tax. Federal tax is $287.38, Hawaii tax is $157.89, Social Security is $186.00 and Medicare is $43.50. Over a year that is about $56,556 in take-home pay.
Questions
Why are the Hawaii withholding rates lower than the income tax rates?
Withholding uses its own set of bands, topping out at 7.9%, while the tax on a finished return has higher top rates. The difference is settled when you file.
What is the extra withholding allowance?
It is a fixed yearly amount that the state's withholding method subtracts from everyone's pay before applying the bands. You can change it here if the state changes it.
Which table do heads of household use?
Booklet A puts unmarried heads of household with single people, so choose the single option for the Hawaii part. The federal part uses the head of household brackets when you pick that status.
