Most Expensive States: What You're Really Paying

Hawaii's cost of living index is 193.3. That means a lifestyle that costs $100,000 anywhere else in the country costs $193,300 in Honolulu. That's not a rounding error. That's a second income.

The 10 Most Expensive States in 2026

Ranking states by cost of living requires more than median home prices. It means stacking housing, groceries, transportation, healthcare, and taxes into a single number. Here's how the top ten shake out:

• Hawaii — Cost of living index: 193.3. Annual income needed to live comfortably: $141,127.
• Massachusetts — Index: ~150. Comfortable income needed: $118,431.
• California — Index: ~142. Comfortable income needed: $107,357.
• New York — Median home price above $400,000 statewide, with New York City pushing well beyond $700,000.
• Alaska — Remote geography drives grocery and fuel costs sharply higher. Comfortable income needed: $100,289.
• Maryland — Property taxes average 1.09% effective rate, and the state adds a local piggyback income tax on top of state rates.
• Washington — No income tax, but a median home price above $575,000 and a 6.5% state sales tax close the gap fast.
• Connecticut — Top marginal income tax rate of 6.99% and a median home price over $380,000.
• New Jersey — The highest effective property tax rate in the country at 2.13%, plus a top income tax rate of 10.75%.
• Oregon — Top state income tax rate of 9.9%, and Portland metro housing costs rival Seattle.

The common thread: high housing costs and high taxes compound each other. Paying 10% income tax on a $120,000 salary hurts more when your mortgage already consumes 40% of take-home pay.

Why Taxes Tip the Scale

People underestimate how much the tax layer adds to already-high costs. California's top marginal income tax rate is 13.3%, the highest in the nation. A household earning $300,000 in San Francisco pays that rate on every dollar above $1 million, but also faces a 1.1% average effective property tax rate on a median home worth over $700,000.

New Jersey compounds the problem differently. The state's 2.13% effective property tax rate means a $400,000 home costs $8,520 per year in property taxes alone, before insurance, maintenance, or mortgage interest. That's $710 per month added to your housing bill.

Washington sidesteps income tax but compensates with aggressive sales taxes. Seattle's combined sales tax rate hits 10.25%. Spend $60,000 per year on taxable goods and services and you're writing the state a $6,150 check annually.

The Hidden Costs Most People Miss

The cost of living index captures groceries and rent. It doesn't fully capture what happens when you combine a high-cost state with a high-tax structure and then factor in the assets you're building.

Estate taxes are one example. Massachusetts and Oregon both impose state-level estate taxes with exemptions as low as $1 million. In a state where a median home already costs $500,000, a $1 million estate is not a wealthy family. It's a house and a retirement account. Our post on Estate Tax by State: Where Your Heirs Pay Most covers exactly how much each state takes.

Capital gains treatment is another gap. California taxes capital gains as ordinary income, up to 13.3%. Sell a home with $500,000 in appreciation and the state wants up to $66,500. That's on top of federal capital gains tax.

Property tax relief is one area where some expensive states partially offset costs. Connecticut and Maryland offer homestead exemptions, but they rarely close the full gap. Our guide to States With the Lowest Property Taxes shows where the real deals are.

What You Should Do With This Information

Comparing states on one metric at a time produces bad decisions. A state with no income tax can still be expensive when housing and sales taxes are factored in. A state with high income taxes can be a net positive if housing costs are low enough to offset them.

The only way to know your actual number is to model it against your specific income, spending habits, and asset picture.
