10 Most Expensive States to Live in 2026
Hawaii tops the most expensive list at nearly twice the national average cost of living. California, Massachusetts, and New York are close behind. Here is what drives the high costs and what you actually pay for everyday expenses in each state.

Why Each State Is So Expensive
Hawaii: Island Isolation
Nearly every consumer good must be shipped to the islands. Food, building materials, fuel, and manufactured goods all carry a significant shipping premium. Local production of food is limited by land area. A gallon of milk in Honolulu costs $6 to $9 versus $3 to $4 in the Midwest. Electricity rates in Hawaii average over $0.40 per kWh, compared to $0.13 nationally. Housing is scarce on limited land with high demand from both residents and vacation buyers.
California: Supply Restrictions and Taxes
California's housing cost problem is primarily supply-side: restrictive zoning, lengthy permitting processes, and high construction costs have limited new housing production for decades. The state has 13.3% top income tax rate, sales taxes of 7.25% to 10.75%, and high property taxes in absolute dollar terms (though Prop 13 caps rate increases for existing owners). Gasoline also runs $1 to $1.50 more than the national average due to unique fuel blend requirements and taxes.
New Jersey: Property Taxes
New Jersey has the highest effective property tax rate in the country at approximately 2.1% to 2.5% of assessed value. On a $475,000 home, that is $10,000 to $12,000 per year in property taxes alone, or $833 to $1,000 per month added to your housing cost. This fundamentally shifts the financial calculation compared to low-property-tax states. Even if you buy at a lower price, the carrying cost of ownership remains very high.
Within-State Variation Matters
State averages mask significant variation within state borders. New York State has a cost of living index near 139, but that is dominated by New York City and its suburbs. Buffalo, Rochester, and Syracuse have cost of living indexes of 90 to 95, well below the national average. A remote worker who can live anywhere in New York can find genuinely affordable options despite the state's overall expensive reputation.
Similarly, California's cost of living varies enormously. San Francisco and Los Angeles are extreme outliers. Fresno, Bakersfield, and Redding have housing costs 40% to 60% lower than the Bay Area. For people who must live in a high-cost state for family or lifestyle reasons, the choice of city within the state can matter as much as the state choice itself.
