Hawaii Income Tax Brackets & Rates 2026

Hawaii Income Tax Overview for 2026

Hawaii (HI) uses a graduated income tax system with 12 brackets, where rates range from 1.4% to 11%. Hawaii has 12 tax brackets, among the most of any state, with a top rate of 11%.

For the 2026 tax year, Hawaii residents must file both state and federal income tax returns. Your HI state tax is calculated on your state taxable income, which generally starts with your federal adjusted gross income (AGI) and applies state-specific adjustments and deductions. The Hawaii standard deduction is $2,200 for single filers and $4,400 for married couples filing jointly.

Because Hawaii uses graduated brackets, your effective tax rate will be lower than the top marginal rate. Only the portion of income within each bracket is taxed at that rate. Your combined federal and HI effective tax rate depends on your total income, filing status, deductions, and credits.

SALT Deduction and Hawaii Taxes in 2026

The State and Local Tax (SALT) deduction allows taxpayers who itemize on their federal return to deduct state and local taxes paid, including state income taxes and property taxes. Under the One Big Beautiful Bill Act (OBBBA), the SALT cap has been raised to $40,000 for the 2026 tax year, up from the $10,000 cap that was in place since 2018.

For Hawaii residents, this is significant. With a top state rate of 11%, many HI taxpayers pay substantial state income taxes. Combined with property taxes, the $40,000 SALT cap provides meaningful relief compared to the previous $10,000 limit. Taxpayers should compare their total SALT amount against the $40,000 cap to determine whether itemizing benefits them over the standard deduction.

The $40,000 SALT cap applies to the combined total of state income taxes (or sales taxes if elected), local income taxes, and property taxes. This cap is the same regardless of filing status. Use our SALT Deduction Calculator to determine your optimal strategy.

How Federal Taxes Apply to Hawaii Residents

All Hawaii residents are subject to federal income tax, which uses seven progressive brackets for 2026: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The federal standard deduction is $16,100 for single filers and $32,200 for married filing jointly. Under the OBBBA, new provisions include tax-free overtime pay, tax-free tips for service workers, and an additional $4,000 deduction for seniors aged 65 and older.

Your total tax liability as a HI resident combines your federal tax obligation with your Hawaii state tax plus FICA taxes (Social Security at 6.2% and Medicare at 1.45%). Self-employed individuals in Hawaii owe both the employee and employer portions of FICA (15.3% total) but can deduct the employer portion.

Tax Planning Tips for Hawaii Residents

• Evaluate itemizing vs. standard deduction: With the $40,000 SALT cap, HI residents with high state income and property taxes should compare their itemized deductions against the standard deduction each year.
• Maximize retirement contributions: Contributing to a 401(k) or traditional IRA reduces both your federal and Hawaii taxable income, providing a double tax benefit.
• Consider HSA contributions: If eligible, an HSA provides triple tax savings: deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses. The 2026 limit is $4,300 for individuals.
• Review withholding: Use your combined federal and state tax liability to ensure proper withholding, avoiding both underpayment penalties and excessive refunds.
• Track estimated payments: If you have self-employment income or significant investment income, make quarterly estimated payments to both the IRS and Hawaii to avoid penalties.

Hawaii vs. Other States: Tax Comparison

Compared to the national landscape, Hawaii's top rate of 11% is above average. States like Florida, Texas, and Nevada have no income tax at all, while states like California (12.3%) and New York (10.9%) have even higher top rates. When comparing states, consider the full tax picture including property taxes, sales taxes, and cost of living, not just income tax rates.
