Can California Tax Your Pension After You Move Out of State?

California cannot tax your pension after you move out of state, provided you have genuinely become a resident somewhere else. Federal law blocks any state from taxing retirement income paid to someone who no longer lives or is domiciled there, and that protection covers traditional pensions, 401(k) distributions, IRA withdrawals, and CalPERS and CalSTRS benefits. The complication is that California’s Franchise Tax Board decides whether your move was real, and with a top income tax rate of 13.3%, the state has strong incentive to look closely.

The Federal Law That Shields Your Pension

Under 4 U.S. Code § 114, no state may impose income tax on retirement income paid to a person who is not a resident or domiciliary of that state.¹ The statute was enacted in 1996 and applies directly to California. Once you are genuinely a non-resident, California loses its authority to tax the pension you earned there.

The protected categories are broad:

Qualified employer plans, including 401(k)s, 401(a) pension plans, and profit-sharing plans
403(a) annuity plans and 403(b) tax-sheltered annuities used by governments and nonprofits
Traditional IRAs and SEP-IRAs
Eligible 457(b) deferred compensation plans offered by state and local governments

Public pensions earned through decades of California employment are covered. CalPERS pensions come from qualified trusts under IRC Section 401(a), placing them squarely inside the federal protection, and CalSTRS and other public retirement systems work the same way.¹

The Ten-Year Rule for Nonqualified Deferred Compensation

Nonqualified deferred compensation, common in executive pay packages, gets protected only under narrower conditions. Section 114 shields nonqualified plan income only if the payments are made as a series of substantially equal periodic payments over your life expectancy (or the joint life expectancy of you and a beneficiary), or over a period of at least ten years.²

Excess benefit plans, which pay retirement benefits above IRS contribution and benefit caps, are also protected regardless of the payment schedule.²

A lump-sum payout from a nonqualified plan, or one spread over fewer than ten years without fitting the life-expectancy or excess-benefit categories, is not protected. California can source that income to the state and tax it. This trips up executives who accept lump-sum payouts around the time they leave.

Income California Can Still Tax After You Leave

The pension shield covers retirement income, not everything you receive after moving. Under Revenue and Taxation Code Section 17951, California taxes non-residents on income derived from California sources.³ Several categories keep their California character no matter where you live.

Stock options and restricted stock units granted for California services stay California-source income when you exercise or vest, even years later. The FTB sources this income to where you performed the work, not where you lived when the payout occurred.⁴ The same logic applies to deferred compensation tied to services performed in California.⁵

Rental income from California property and capital gains from selling California real estate remain taxable in California.⁵ So does income from a California-based business, partnership, or S-corporation you have an interest in.

Proving You Are No Longer a California Resident

The federal protection only applies once you are actually a non-resident, and California defines residency by where your life is centered, not by your driver’s license alone. A resident is anyone in the state for other than a temporary or transitory purpose, or anyone domiciled in California but temporarily outside it.⁶

The FTB compares your ties to California against your ties to your new state. The factors it weighs include:

Days spent in California versus your new state
Where your spouse and children live
The location of your principal residence
Which state issued your driver’s license and registered your vehicles
Where you are registered to vote
Where you maintain professional licenses
Where you bank and initiate financial transactions
Where your doctors, dentists, and other providers are located
Club, religious, and professional memberships
Where you own real estate and hold investments

No single factor decides the question. The FTB looks at the overall picture and weighs the strength of each connection.⁷ A vacation home in California is not fatal by itself. A vacation home plus your longtime doctor, your country club, and your voter registration is a different story.

Professional Licenses

The FTB specifically considers whether you maintain an active California professional license when identifying your closest connections.⁸ If you hold a California medical, legal, CPA, or real estate license you no longer need, letting it lapse or moving it to inactive status removes one argument against you. Keeping it active for occasional California work is not fatal, but it counts against your non-residency position.

The Six-Month Visitor Rule

California regulations offer some protection for people who keep a home in the state but live elsewhere. If you are domiciled outside California, maintain a permanent home at that domicile, spend fewer than six months total in California during the tax year, and confine your California activities to those of a seasonal visitor or tourist, you are generally treated as present only for a temporary purpose.⁹ Owning a California home and holding local bank accounts for personal expenses is compatible with this treatment. Conducting business or performing services in California is not.

Filing the Year You Move

In the year you leave California, you file Form 540NR as a part-year resident, whether you moved in January or in December.¹⁰ Schedule CA (540NR) allocates your income between the resident portion of the year (all income taxable) and the non-resident portion (only California-source income taxable), and the two combine into your California taxable income for the year.¹¹

Pension distributions received while you were still a California resident are fully taxable. Distributions received after your residency ended are generally excluded under the federal protection, unless they fall inside one of the nonqualified deferred compensation exceptions.

Stopping California Withholding on Your Pension

Pension administrators often keep withholding California tax until you tell them otherwise. File Form DE 4P, Withholding Certificate for Pension or Annuity Payments, with your plan administrator to elect out of California withholding.¹² If you skip this step you will keep overpaying and then claiming refunds, which creates a cash-flow drag and hands the FTB a data point suggesting you still consider yourself connected to California. Set up withholding for your new state if it taxes retirement income; several states do not tax it at all, and others tax it well below California’s rates.

If the FTB Challenges Your Move

California audits high-income taxpayers who claim to have left more aggressively than most states. The FTB generally has four years from the date you file to open an audit, six years where it alleges a substantial understatement, and no limit at all in fraud cases.

If the FTB concludes you were still a California resident, the exposure is significant:

Back taxes on your worldwide income for every year reclassified as residency
An accuracy-related penalty of 20% of the underpayment for negligence or substantial understatement¹³
A fraud penalty of 75% of the underpayment where the FTB shows intentional evasion¹³
Interest compounding from the original due date

Documentation is the best defense. Keep records of your move date, your new lease or home purchase, the date you changed your driver’s license and voter registration, and the date you updated your address with banks and brokers. Save travel records that show how many days you spent in California each year after the move. When an audit letter arrives years later, contemporaneous documents carry more weight than any argument you can make from memory.

For most retirees drawing on traditional pensions, 401(k)s, and IRAs, the federal shield under 4 U.S.C. § 114 is direct and reliable. California cannot tax that income once you are a non-resident. The real work is making sure California agrees that you are.
