California vs Hawaii: America's two highest income tax states face off across the Pacific
California and Hawaii occupy a unique shared distinction: they impose the two highest top marginal income tax rates in the nation. California's top rate is 13.3% on income above $1 million, while Hawaii reaches 11% on income above $200,000 (or $400,000 for joint filers). For high earners, both states are punishingly expensive from a tax perspective—but the details of who pays what differ significantly based on income level and lifestyle.
Hawaii and California land far closer together than their headline rates suggest, and which one costs more depends on where you sit. Hawaii's 11% bracket kicks in much earlier—at $200,000 for single filers—while California's rates are more graduated, with the 11.3% bracket not hitting until $698,271. Hawaii is the dearer of the two for a single filer near $100,000 (about $5,800 against $5,100), but California overtakes it from roughly $150,000 up: at $200,000 a single filer pays about $14,400 in California against $13,600 in Hawaii. It's only at very high incomes (above $1 million) that California's 13.3% rate overtakes Hawaii.
The cost-of-living comparison is brutally expensive on both sides. Hawaii has the highest overall cost of living of any state, driven by housing, groceries (30-50% above mainland prices), and energy costs. California's coastal metros (SF, LA, San Diego) rival Hawaii's costs, but inland areas like Sacramento and the Central Valley are considerably cheaper. Property taxes offer a stark contrast: Hawaii's 0.27% effective rate is the lowest in the nation, while California's 0.70% is moderate. Prop 13 limits California reassessments, but Hawaii's base rate is simply much lower.
Key Differences Beyond Income Tax
| Category | Hawaii | California |
|---|---|---|
| Property Tax | Effective rate ~0.71%; Prop 13 caps increases at 2%/year; reassessment only on sale or new construction | Effective rate ~0.32%—lowest in the nation; homeowner exemption of $100,000 on primary residence |
| Sales Tax | Base rate 7.25%, combined up to 10.75%; groceries exempt; highest base rate in the nation | General excise tax (GET) of 4% (4.5% on Oahu); applies broadly including to services and some business-to-business transactions—effectively a hidden tax on everything |
| Cost of Living | Coastal metros extremely expensive; inland areas moderate; groceries slightly above national average | Highest cost of living in the nation; groceries 30-50% above mainland; electricity 2-3x national average |
| Retirement Income | Social Security exempt; all other retirement income taxed as ordinary income at up to 13.3% | Social Security exempt; pension income from contributory government plans exempt; other retirement income taxed at up to 11% |
| Estate Tax | No state estate tax (repealed in 1982) | State estate tax with exemption tied to federal ($13.99M in 2025, rising to $15M in 2026 under OBBBA); top rate 20%—one of the highest state estate tax rates |
Who Benefits from Moving?
Tech workers earning $200K-$500K
A software engineer earning $300,000 pays roughly $23,800 in California income tax versus $22,600 in Hawaii—Hawaii is actually about $1,200 cheaper at this income level, not more expensive, even though Hawaii's 11% bracket hits earlier. Combined with Hawaii's astronomical cost of living, California wins financially for most tech workers.
Millionaires and ultra-high earners
At $2 million income, California's 13.3% top rate produces a tax bill of roughly $230,000 versus Hawaii's approximately $205,000. Above about $1.5M in income, California becomes the more expensive state. But at these income levels, both states cost dramatically more than lower-tax alternatives.
Retirees comparing Maui and San Diego
A retiree with $120,000 in retirement income (pension + IRA) pays about $7,200 in California tax. In Hawaii, with pension exemptions for qualifying plans, the bill could be as low as $3,000-$5,000—but groceries, utilities, and healthcare in Hawaii will easily consume those savings and then some.
Bottom line: At $150,000 income the two states land within about $60 of each other—Hawaii around $9,640 against California's $9,710—so for a typical high earner the income tax is close to a wash, and the decision turns on cost of living rather than on California's higher top marginal rate.

Understanding Each State
Hawaii
This state uses a progressive income tax system with multiple brackets, similar to the federal system. Only the income within each bracket is taxed at that rate, so your effective state rate is lower than the top bracket. Tax planning strategies include maximizing pre-tax retirement contributions to reduce state-taxable income.

California
California has the highest top marginal state tax rate in the US at 13.3%, with progressive brackets starting at 1%. An additional 1% Mental Health Services Tax applies to incomes over $1 million. Despite high taxes, California's economy — tech, entertainment, agriculture — attracts top talent globally. Under OBBBA, the SALT deduction cap rose to $40,000 for 2025 and $40,400 for 2026 (half that if MFS), but is cut by 30 cents for every dollar of MAGI above $500,000 for 2025 ($505,000 for 2026), down to a $10,000 floor — so the highest-income California itemizers see only partial federal relief.

Key Comparison Points
Income tax structure: Hawaii has a progressive income tax (1.4% – 11%), while California has a progressive income tax (1% – 13.3%).
Beyond income tax: State tax comparisons should also consider property tax rates, sales tax, and cost of living. A state with no income tax may have higher property or sales taxes that offset the savings.
SALT deduction cap: Under OBBBA, the 2026 federal SALT cap is $40,400, phasing out above $505,000 MAGI toward a $10,000 floor. This limits the federal tax benefit of living in a high-tax state, so the gross state tax difference remains close to the net difference for most earners — especially high earners inside the phaseout.
