California has the highest marginal income tax rate in the country at 13.3%. Nevada has zero. That gap is why more California retirees move to Las Vegas than any other destination. We ran the actual math for three different California households — modest, comfortable, and high-income — so you can find your scenario and see what you're actually leaving on the table by staying.
Before the scenarios, here's what California actually taxes in retirement:
| Income Type | California Rate | Nevada Rate | Annual Saving (per $100K) |
|---|---|---|---|
| IRA / 401(k) distributions | 1%–13.3% marginal | 0% | $2,000–$13,300 |
| Social Security income | Taxable above threshold | 0% | Up to $3,200 |
| Pension income | Taxable (CA public pensions exempt) | 0% | $2,000–$9,000+ |
| Capital gains (long-term) | Taxed as ordinary income | 0% | $1,000–$13,300 |
| Investment dividends | Taxed as ordinary income | 0% | $500–$5,000+ |

California's Franchise Tax Board actively audits residents who claim Nevada domicile while maintaining significant California ties. If you spend more than half your time in California, maintain a California home, or have business interests there, you remain subject to California taxation. True Nevada domicile requires: Nevada driver's license (get it within 30 days), Nevada voter registration, Nevada bank accounts, Nevada estate documents — and spending the majority of your time here. The savings above require genuine relocation, not a P.O. box. Consult a tax attorney who specializes in California domicile exits before relying on any of these projections.
