California Will Never Tax a Dime of Shohei Ohtani’s $680 Million. The Federal Law He’s Counting On Also Protects Your 401(k) the Day You Retire Across State Lines
A 30-year-old federal statute already blocks high-tax states from following your retirement savings across state lines, but one timing mistake voids the entire protection and hands your old state exactly what it wanted.

If you own a 401(k), IRA, 403(b), or pension in a high-tax state and plan to retire somewhere cheaper, a 30-year-old federal statute has already done the hardest part of your tax planning. The state where you earned that retirement money cannot tax a single dollar of it once you become a resident somewhere else. That is the exact rule shielding Shohei Ohtani’s deferred $680 million from California if he ever leaves, and it protects your rollover the day your U-Haul crosses the border.
The Buried Rule Inside Every Qualified Plan
The Pension Source Tax Act of 1996 flatly prohibits any state from taxing the retirement income of a person who no longer lives there. If you spent 30 years contributing to a 401(k) in California, New York, or New Jersey, and you retire to Florida, Tennessee, or Wyoming, your old state loses jurisdiction the moment you establish domicile elsewhere. It does not matter that the money was earned in-state, matched in-state, or deferred in-state. Distribution follows the retiree, not the employer.
The Statute Doing the Work
The credibility anchor is 4 U.S. Code § 114, enacted as Public Law 104-95 on January 10, 1996. The text is unusually blunt for tax law: “No State may impose an income tax on any retirement income of an individual who is not a resident or domiciliary of such State.” Congress passed it specifically to stop California and other high-tax states from chasing former residents into retirement.
This is the same mechanism Ohtani’s camp is leaning on. His Dodgers contract defers $68 million annually, paid on July 1 of each year from 2034 through 2043, totaling $680 million without interest. During his playing years, he draws just $2 million per season. If he is domiciled outside California when those deferred checks arrive, California, which ranks 48th in overall tax competitiveness on the Tax Foundation’s 2026 State Tax Competitiveness Index and carries a 13.3% top marginal individual income tax rate (14.4% when the uncapped payroll tax is included), collects nothing. That is a potential state tax bill north of $90 million that simply evaporates with a change of address.
What Qualifies, and What Doesn’t
The protection covers qualified plans you already recognize: 401(k), 403(b), 457(b), traditional and Roth IRAs, SEP-IRAs, SIMPLE IRAs, defined-benefit pensions, and ESOPs. It also covers nonqualified deferred compensation, but only when payments are made in substantially equal periodic installments over your life expectancy or over a period of at least 10 years. A single lump-sum payout from a nonqualified plan is fair game for your old state.
The shield does not extend to regular wages earned before you moved, stock options exercised after leaving, RSUs that vest post-move for pre-move work, or severance. The statute protects retirement income. It does not protect deferred W-2 income restructured to look like it.
Locking It In
- Change your domicile before your first distribution. Driver’s license, voter registration, physical residence, mailing address, doctors, and vehicle registration should all move. A second home in Nevada while you keep the California house does not cut it.
- If you have nonqualified deferred comp, elect installment payments of 10 years or longer under Section 409A rules before separation. A lump sum forfeits the shield.
- Roll your 401(k) into an IRA after you have moved. The protection travels with the account.
- Keep dated records proving where you slept. High-tax states run residency audits, and the burden falls on you.
- Compare real purchasing power, not just headline rates. BEA Regional Price Parity data for 2024 puts California’s cost-of-living index at 110.7, the highest of any state in the country, while Wyoming carries no state income tax and, after adjusting for local prices, leads all states in real per capita personal income at $75,501.
The Trap That Voids the Whole Thing
The catch is domicile, and California fights it aggressively. The Franchise Tax Board can claim you never truly left if your “closest connections” remained in-state. Family ties, business interests, bank accounts, safe deposit boxes, professional licenses, church memberships, and even gym memberships all get scored. A single distribution taken before the move is legally complete is taxable by the old state, and it can drag later payments into audit territory.
The statute is federal and airtight, but it only protects nonresidents. Prove the move first, then take the money. With the national personal saving rate sitting at 2.8% in the second quarter of 2026, according to the Bureau of Economic Analysis, every dollar of retained retirement income matters. This statute is the largest single protection hiding in plain sight inside your plan documents.
Editor’s note: This article was updated to reflect the Tax Foundation’s 2026 State Tax Competitiveness Index, which ranks California 48th overall (up from the previously cited 49th), and to add California’s 13.3% top marginal income tax rate and 14.4% all-in rate including the uncapped payroll tax. The cost-of-living comparison was corrected using BEA Regional Price Parity data for 2024, which shows California’s index at 110.7 as the highest in the nation, and Wyoming’s real per capita personal income at $75,501 as reported by the BEA in February 2026. Ohtani contract payment mechanics were also clarified to reflect the $68 million annual installment structure.
