Hawaii Standard Deduction

For tax year 2024, the Hawaii standard deduction is $2,200.00 for single filers and $4,400.00 for married couples filing jointly, as published by the Hawaii Department of Taxation. It is subtracted from your gross income to give your Hawaii taxable income.

The standard deduction lowers your Hawaii taxable income, which is the figure the state income tax brackets are applied to. A single filer with $60,000.00 of gross income and the $2,200.00 standard deduction has $57,800.00 of Hawaii taxable income before any other adjustments.

Take whichever is larger. If your total itemised deductions allowed by Hawaii exceed the standard deduction of $2,200.00 (single) or $4,400.00 (married jointly), itemising lowers your taxable income more. Otherwise the standard deduction is simpler and larger. Check the rules with the Hawaii Department of Taxation.

Hawaii's top rate of 11% is one of the highest in the nation, reflecting the state's revenue needs and fiscal structure. Hawaii relies heavily on income tax because it replaced a traditional sales tax with the General Excise Tax (GET), which applies at a low rate (4%) to a very broad base including most services. The income tax helps fund public services on islands where the cost of government services is elevated due to geographic isolation and reliance on imported goods. The legislature has maintained and in some cases expanded the high upper brackets over time.

Hawaii has 12 brackets for 2024. For single filers: 1.4% on $0-$2,400; 3.2% on $2,401-$4,800; 5.5% on $4,801-$9,600; 6.4% on $9,601-$14,400; 6.8% on $14,401-$19,200; 7.2% on $19,201-$24,000; 7.6% on $24,001-$36,000; 7.9% on $36,001-$48,000; 8.25% on $48,001-$150,000; 9% on $150,001-$175,000; 10% on $175,001-$200,000; and 11% above $200,000. Married filing jointly thresholds are double the single amounts. Authority: Hawaii Department of Taxation, Hawaii Revised Statutes §235-51.

Hawaii sets its own standard deduction under Hawaii Revised Statutes §235-54, separate from the federal amount. For 2024 the Hawaii standard deduction is $2,200 for single filers and $4,400 for married filing jointly, compared to the federal amounts of $14,600 and $29,200. Hawaii has historically kept its own standard deduction low, which increases the taxable income base and thus the effective tax burden on residents. Hawaii does offer personal exemptions and various credits that partially offset this difference.

Hawaii does not tax Social Security benefits. However, Hawaii does tax most other forms of retirement income, including distributions from 401(k) plans, IRAs, and pensions from private employers. Hawaii does exempt certain public pension income, including distributions from the Hawaii Employees' Retirement System (ERS). Retirees with significant private retirement income should factor Hawaii's high income tax rates into their planning. See Hawaii Revised Statutes §235-7 for exclusions.
