Why a $2.1 Million 401(k) Holder Is Moving From California to Nevada Before His First RMD at 73

A 70-year-old single retiree in Walnut Creek with $2.1 million in a traditional 401(k), $40,000 a year in Social Security, and a $500,000 taxable brokerage is doing something his financial advisor pushed for two years: he is closing on a house in Henderson, Nevada this summer. His first required minimum distribution arrives at age 73. He wants to be a Nevada resident for a full calendar year before that distribution hits his 1099-R.

The driver is a roughly $220,000 net-present-value tax savings that California will otherwise collect from his retirement account, one RMD at a time.

The California Drag on a $2.1 Million 401(k)

California treats every dollar of a traditional 401(k) withdrawal as ordinary income, with marginal rates climbing to 12.3%. On top of that, the state levies a 1% Behavioral Health Services Tax (still widely called the mental health services surtax) on taxable income above $1 million, pushing the effective top rate to 13.3%. Unlike the federal code, California offers no preferential rate for qualified dividends or long-term capital gains, so his $500,000 brokerage account faces the same ordinary-income ladder.

The Social Security calculation matters here, but not the way most people assume. California is one of roughly 41 states that fully exempt Social Security benefits from state income tax, so his $40,000 annual benefit creates zero California tax liability by itself. At the federal level, however, a large RMD pushes his provisional income well above the $34,000 single-filer threshold, making up to 85% of that Social Security federally taxable. That federal inclusion raises his overall adjusted gross income, which in turn drives his California taxable income higher because his 401(k) distributions are fully taxable at the state level.

At 73, his first RMD on a compounded balance lands near $130,000. That distribution alone, stacked on top of other income, puts his California marginal rate on the RMD dollars at around 9.3%. The annual state-tax bill on RMDs alone runs $10,000 to $12,000. Project that forward across the Uniform Lifetime Table for 20 years, with the balance still growing between distributions, and the cumulative California tax on RMDs reaches $200,000 to $240,000.

Nevada charges zero state income tax. The 2026 State Tax Competitiveness Index from the Tax Foundation ranks Nevada 20th overall and California 48th overall, a gap that reflects not just income tax rates but the entire structure of each state’s tax code.

Why the Move Has to Happen Before the RMD Year

The RMD itself is federal. The state-tax exposure is about where you legally reside when the money hits your account. Becoming a Nevada resident in the same calendar year as the first RMD invites California to claim a piece of that distribution on a part-year return. Establishing domicile a full 12 months before the first RMD year takes the entire withdrawal off California’s books.

The California Franchise Tax Board does not let high-net-worth departures go quietly. In 2023, the FTB completed 520 residency audits on out-of-state individuals, more than double the number conducted in 2019. The agency uses a “close connection” test that weighs club memberships, driver’s license location, family location, and even the origination points of phone calls. Keeping what the FTB considers a primary or luxury home in California while claiming residency elsewhere is a primary audit trigger.

Defensible Nevada residency means far more than a mailing address. Our retiree is selling the Walnut Creek house (or converting it to an arm’s-length rental), pulling a Nevada driver’s license, registering to vote in Clark County, moving primary banking and brokerage to a Nevada address, establishing a Nevada physician of record, and documenting fewer than 183 days a year inside California.

Three Moves Before the Calendar Turns

1. Anchor the residency clock now. If the first RMD will arrive in the year he turns 73, every domicile change (license, voter registration, primary physician, bank statements) should be timestamped at least 12 months earlier. Save utility bills, cell-tower records, and travel itineraries: the FTB challenges these claims years after the move.
2. Handle the California house with the tax in mind. A clean sale captures the $250,000 Section 121 exclusion for a single filer and severs a major audit trigger. Renting it through an LLC works only if the lease is arm’s-length and he stops using the property as a part-time residence.
3. Re-domicile the planning alongside the person. Revocable trusts, beneficiary designations, and the estate plan should be redrafted under Nevada law alongside the move. Nevada’s creditor and trust statutes are an added benefit that disappears if the paperwork still points to California.

For a retiree with a seven-figure traditional 401(k), the RMD schedule is fixed by the IRS. The state that taxes those distributions is a choice.
