Hawaii applies a distinct capital gains tax rate that is lower than its highest ordinary income tax brackets. While federal long-term and short-term capital gains rules determine how much gain is recognized and taxed by the IRS, Hawaii adds its own state-level layer. Understanding how Hawaii’s unique approach interacts with federal tax law is essential for investors, real estate owners, and business sellers preparing for taxable events in 2025.
What Are Capital Gains?
Capital gains occur when you sell a capital asset for more than your adjusted basis. Hawaii follows federal rules to determine what counts as a capital asset and how gains are calculated. Assets that frequently generate gains include stocks, bonds, real estate, cryptocurrency, business interests, and collectibles.
There are two types of capital gains:
- Realized Capital Gains: Gains recognized when an asset is sold. These create a taxable event at both the federal and Hawaii state levels.
- Unrealized Capital Gains: Gains on unsold assets. These increases in value are not taxed until you sell the asset.
Hawaii taxes only realized gains and applies a fixed tax rate rather than a progressive bracket structure.
Long-Term vs. Short-Term Capital Gains
Federal tax rules distinguish capital gains based on how long you held the asset before selling it. This classification affects federal tax liability, which combines with Hawaii’s state tax.
- Short-Term Capital Gains: Gains on assets held 1 year or less. These are taxed federally as ordinary income at rates from 10% to 37% in 2025.
- Long-Term Capital Gains: Gains on assets held for more than 1 year. These qualify for lower federal rates of 0%, 15%, or 20%.
Hawaii does not differentiate between long-term and short-term gains for the purpose of applying its state tax rate. The state uses the same fixed rate of 7.25% regardless of holding period.

Hawaii Capital Gains Tax in 2025
Hawaii imposes a maximum capital gains tax rate of 7.25% on realized gains. This is a distinct rate that applies instead of Hawaii’s higher ordinary income tax brackets.
Key points for Hawaii taxpayers:
- Hawaii taxes all capital gains at a 7.25% rate.
- This rate is lower than Hawaii’s top ordinary income rate, which exceeds 10%.
- Hawaii does not differentiate between long-term and short-term gains for state tax purposes.
- Gains excluded federally, such as the Section 121 home sale exclusion, are generally excluded in Hawaii as well.
- Hawaii conforms to federal gain-recognition rules but applies its own fixed rate.
- Taxpayers should watch for potential legislative proposals to increase the 7.25% rate, as such discussions occur regularly in the state legislature.
Case Study: How Capital Gains Taxes Apply in Hawaii
A Hawaii resident earns $130,000 in wages and realizes a $60,000 long-term capital gain from selling stock.
- Federal Impact:
- The $60,000 gain falls into the 15% federal long-term bracket.
- Federal tax owed is approximately $9,000.
- NIIT may apply if the taxpayer’s modified adjusted gross income exceeds federal thresholds.
- Hawaii Impact:
- Hawaii applies its fixed 7.25% capital gains rate.
- State tax owed is $60,000 × 7.25% = $4,350.
Total combined tax liability: approximately $13,350, plus NIIT if triggered.
Strategies to Reduce Capital Gains Taxes
With Hawaii applying a distinct capital gains rate and federal law imposing its own layers of taxation, effective planning focuses on coordinated strategies.
- Hold assets for more than 1 year: This reduces your federal tax rate even though Hawaii applies the same rate regardless.
- Harvest tax losses: Realized losses can offset gains and reduce the amount subject to federal and Hawaii taxes.
- Time recognition for lower-income years: Lower federal income may reduce long-term bracket impact and avoid NIIT.
- Use 1031 exchanges for real estate: Defers both federal and Hawaii gain recognition for qualifying properties.
- Review legislative proposals: Hawaii frequently considers raising capital gains tax rates, which can influence timing decisions.
Conclusion
Hawaii capital gains tax in 2025 is based on a fixed 7.25% rate applied to all realized gains. While this is lower than the state’s highest ordinary income tax brackets, it still creates a meaningful tax burden when combined with federal rules. By leveraging holding periods, loss-harvesting strategies, and deferral techniques, Hawaii taxpayers can reduce total exposure and plan capital transactions more effectively.
