Hawaii Capital Gains Tax Calculator
Hawaii taxes capital gains as ordinary income at the state level, which means a gain on selling shares, property or other investments is added to your other income and taxed using the Hawaii income tax brackets, with no separate preferential long-term rate like the federal system provides. This calculator estimates the Hawaii state tax on a capital gain by stacking the gain on top of your other taxable income and applying the sourced Hawaii Department of Taxation brackets for tax year 2024, then taking the difference. Enter your gain, your other annual taxable income and your filing status to see the state tax attributable to the gain and the effective rate on it. The result is the Hawaii state portion only; federal capital gains tax, which has separate short-term and long-term rates set by the IRS, is calculated separately. Because the gain stacks on your other income, the same gain is taxed at a higher rate the more you already earn. Some states provide specific exclusions or preferential treatment for certain gains; this tool uses the standard ordinary-income method and links the Hawaii Department of Taxation so you can confirm any special rule that applies to you.

Why is Hawaii's income tax so high compared to other states?
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.
What are Hawaii's 2024 income tax brackets and rates?
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.

Why is Hawaii's standard deduction so low?
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.
Does Hawaii tax retirement income and Social Security?
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.
