California Can't Tax Your IRA After You Move. It Can Still Tax the House You Sold.
If you are planning to leave California in retirement, the move changes which state taxes your income, but not all of it and not from the day the moving truck leaves. This applies to anyone with IRAs, 401(k)s, a pension or California real estate who is weighing a move in 2026 or later.
The Short Answer
Under federal law (4 U.S.C. §114), California cannot tax IRA, 401(k), 403(b), 457 or pension distributions you receive after you become a nonresident, and that holds for 2026. California can still tax income you received while you were a resident, gains on California real estate, stock option income tied to work you did here, and some deferred compensation.
Why Can't California Tax My IRA After I Move?
Federal law bars any state from taxing the retirement income of a nonresident. The statute, 4 U.S.C. §114, covers distributions from qualified employer plans such as 401(k)s, IRAs (including SEP IRAs), 403(a) and 403(b) annuities, governmental 457 plans and government pensions. The Franchise Tax Board puts it plainly in its guide for people who change residency: California does not tax the IRA distributions or qualified pension income of a nonresident.
What matters is where you live when the money is paid out, not where you earned it. Thirty years of 401(k) contributions made while working in Los Angeles don't give California a claim on withdrawals you take as a resident of another state. The flip side also holds. A pension check you receive while you are still a California resident is taxable here, even if your move is a month away.
What Can California Still Tax After I Leave?
Some income keeps a California source no matter where you live. The FTB taxes it under nonresident rules, and federal law doesn't protect it.
| Income | Received after you become a nonresident |
|---|---|
| IRA, 401(k), 403(b), governmental 457 and pension distributions | Not taxed by California |
| Nonqualified deferred compensation paid in substantially equal installments over your life or at least 10 years | Not taxed by California |
| Nonqualified deferred compensation paid as a lump sum or over a shorter period | Can be taxed by California, to the extent it was earned for work here |
| Gain on California real estate, including a former home or a rental | Taxed by California |
| Employee stock option income for work performed in California | Taxed by California on the California share |
The deferred compensation line is the one executives miss most often. Federal protection applies only to installment payments that run for life or at least 10 years, or to certain plans that exist solely to pay benefits above the qualified-plan limits. An election made years ago to take a five-year payout can leave that income taxable by California after you have moved away.
How Does California Tax the Income It Still Can?
California taxes a nonresident's California-source income at a rate set by all of their income. The FTB first computes tax as if you were a resident on everything you received, divides that tax by your total income to get an effective rate, and then applies that rate to the California portion.
That means income California can't tax still affects the rate on income it can. Suppose, as a rounded hypothetical, a couple living in Nevada sells a Santa Monica rental for a $400,000 gain in the same year they take $200,000 from their IRAs. California can't tax the IRA withdrawals. It does tax the $400,000 gain, at a rate calculated on $600,000 of income rather than $400,000.
When Does California Decide You Moved?
California, not you, decides when your residency ended. Under state law, you are a resident if you are in California for other than a temporary or transitory purpose, or if your permanent home is still here while you are away temporarily. Spending more than nine months of a year in California creates a presumption of residency, and spending less than nine months creates no presumption either way.
In practice, the state looks at where your strongest ties are. A household that buys a home in another state but keeps the California house and still spends most of its time here may find the move date on its tax return isn't the one the FTB accepts. The FTB's Publication 1031 lays out the factors it weighs.
Does the Timing of the Move Matter?
For anything you choose the timing of, yes. Income received during the part of the year you are a California resident is taxed under resident rules, and California has no lower rate for capital gains. Its top rate reaches 13.3%.
Two decisions show the effect most clearly. A Roth conversion completed in the months before you become a nonresident is California income. The same conversion completed after the move is a distribution California can't tax, though your new state's rules then apply. Selling a California home works the other way: any taxable gain stays California income whenever the sale closes, so moving first doesn't change California's claim on it.
Where It Fits in Your Plan
A move out of California touches your taxes and your house at once, and each has its own calendar. The Tax Management Journey® is built for that problem. It weighs tax decisions across several years and both states, rather than one return at a time, so a conversion and a home sale can each land in the year where it costs least. That often means sequencing the move itself alongside your CPA, because the date you leave sets which state's rules apply to everything that follows.
If you already work with an advisor, the useful question is whether your move date has been part of the tax plan or only part of the moving plan.
