The Tax Math: California vs Nevada
California taxes retirement income — including 401k withdrawals, traditional IRA distributions, and pension income — as ordinary income, up to 13.3% at the top bracket. Nevada has no state income tax at all.
For a retiree withdrawing $80,000/year from a traditional IRA: a California resident in the 9.3% bracket pays $7,440/year in state income tax. A Nevada resident pays $0. Over a 25-year retirement, that difference (before accounting for investment growth of the saved taxes) is $186,000 — nearly 19% of the original $1M portfolio.
Social Security benefits add another layer. California taxes Social Security to the same extent as the federal government (up to 85% of benefits at higher incomes). Nevada does not. For someone receiving $24,000/year in Social Security, that's up to $1,900/year in additional California taxes avoided.
Cost of Living: Where the Savings Are
Nevada's overall cost of living is approximately 5–8% below the US average, while California's is approximately 38–42% above it. The gap is wide, but it's not uniformly distributed across spending categories.
Housing is where the disparity is most extreme. The median home price in the Las Vegas metro is roughly $420,000 vs $800,000+ in the Los Angeles metro and $1.5M+ in the San Francisco Bay Area. For retirees who own their homes outright, this translates directly into lower property taxes (Nevada's effective rate is ~0.5% vs California's ~0.75%, though Prop 13 complicates California comparisons for long-term owners).
Healthcare, groceries, and utilities are more comparable between states. The big financial wins for Nevada retirees are housing costs, income taxes, and for high earners, capital gains taxes (California has no preferential capital gains rate — gains are taxed as income).
Running the Portfolio Math
A $1M portfolio supporting $70,000/year in spending (adjusted for location) lasts approximately 28 years in a California budget scenario (higher taxes, higher COL). The same $1M in Nevada — with the same actual lifestyle quality — requires only about $52,000/year after tax and COL adjustments, extending runway to approximately 35+ years under median return assumptions.
That's 7+ additional years of security from the same portfolio size. In practical terms, it means a retiree with $1M in Nevada can achieve the same lifestyle as someone with $1.35M in California. The geographic arbitrage math is powerful.
These numbers use Sagery's Geographic Arbitrage calculator with 2026 COL indices. Individual results vary based on housing situation, income composition, and spending patterns.
Nevada's Real Trade-offs
Nevada's advantages are real, but so are the trade-offs. Summer temperatures in Las Vegas regularly exceed 110°F, and air conditioning costs are significant. Water is a long-term concern for the entire Southwest — Lake Mead has been at historically low levels, and future restrictions could affect the region.
Nevada's healthcare infrastructure is thinner than California's. Serious medical conditions may require travel to specialists in Utah, Arizona, or California. This matters more as you age.
Reno and Henderson offer more temperate climates than Las Vegas proper, slightly higher COL, but still dramatically better tax treatment than California. The geographic arbitrage benefit isn't limited to the Las Vegas Strip suburbs.
The Part-Transition Strategy
Some California retirees use a "part-year residency" strategy: establish Nevada domicile (utility bills, voter registration, driver's license, primary banking) while spending winters in California near family. California aggressively audits former residents who try to split residency — you need clear, documented proof of Nevada as your primary domicile.
A cleaner approach that avoids scrutiny: complete the move, establish genuine Nevada residency, and use the savings to fund extended visits to California. The after-tax savings of genuine Nevada residency are large enough to pay for a lot of California time.
For retirees whose entire social network, adult children, and healthcare providers are in California, the calculus changes. The financial optimization has to be weighed against what actually makes a retirement meaningful.
