Tax Year 2018 Hawaii Income Tax Brackets
|Tax Bracket||Tax Rate|
|Tax Bracket||Tax Rate|
Both Hawaii's tax brackets and the associated tax rates were last changed two years prior to 2018 in 2016.
Hawaii has twelve marginal tax brackets, ranging from 1.4% (the lowest Hawaii tax bracket) to 11% (the highest Hawaii tax bracket). Each marginal rate only applies to earnings within the applicable marginal tax bracket .
In Hawaii, different tax brackets are applicable to different filing types. Married couples filing their Hawaii income tax return jointly will usually have wider tax brackets than those filing separately or as an individual.
How do Hawaii tax brackets work?
Technically, you don't have just one "tax bracket" - you pay all of the Hawaii marginal tax rates from the lowest tax bracket to the tax bracket in which you earned your last dollar. For comparison purposes, however, your Hawaii tax bracket is the tax bracket in which your last earned dollar in any given tax period falls.
You can think of the bracketed income tax as a flat amount for all of the money you earned up to your highest tax bracket, plus a marginal percentage of any amount you earned over that. The chart below breaks down the Hawaii tax brackets using this model:

Hawaii Tax Deductions
When calculating your Hawaii income tax, keep in mind that the Hawaii state income tax brackets are only applied to your adjusted gross income (AGI) after you have made any qualifying deductions.
Qualifying deductions might include an itemized deduction, the Hawaii standard deduction, exemptions for dependants, business expenses, etc.
Remember that Hawaii may have very different deduction laws from the Federal Income Tax, so you may have to write a whole new list of deductions for your Hawaii income tax return.

Hawaii Standard Deductions & Personal Exemption Amounts
In addition to marginal tax brackets, one of the major features of the Hawaii income tax is deductions. The three most common deductions encountered by taxpayers are the Hawaii Standard Deduction, the Hawaii Personal Exemption, and the Hawaii Dependent Deduction. The current values of these deductions for tax year 2018 are as follows:
|Standard Deduction (Single)||Standard Deduction (MFJ)||Personal Exemption||Dependant Exemption|
The standard deduction, which Hawaii has, is a deduction that is available by default to all taxpayers who do not instead choose to file an itemized deduction. Essentially, it translates to $2,200.00 per year of tax-free income for single Hawaii taxpayers, and $4,400.00 for those filing jointly.
The Personal Exemption, which is supported by the Hawaii income tax, is an additional deduction you can take if you (and not someone else) are primarily responsible for your own living expenses. Likewise, you can take an additional dependent exemption for each qualifying dependent (like a child or family member), who you financially support.
The Federal income tax also has a standard deduction, personal exemptions, and dependant deductions, though they are different amounts than Hawaii's and may have different rules.
