Planning Your Move Out of California: A Tax Timing Playbook for Tech Executives
She is a senior director of product at a publicly traded tech company in San Diego. Nine years in. Her RSUs have quietly stacked into more than $2 million in a single stock. She is thinking about a move to Texas or Florida, and she knows California will not let that equity go quietly. The question is not whether she can leave. It is when, and how, and what the state can still reach after she is gone.
How to diversify RSUs without a tax catastrophe is one piece of the puzzle. The other is understanding that a move out of California is itself a tax event, and one you can plan around if you know the rules before you go.
The $2.4 Million Question: When You Move Matters
California determines residency through two tests: how many days you spend in the state (the 183-day rule) and where your permanent home, or domicile, actually is. Spend more than half the year in California and the state presumes you are a resident. But even when you pass the day count, the FTB can still argue you never really left if your family, your doctor, your club memberships, and your voter registration are all still here.
The single biggest mistake tech executives make is treating the move like a date on a calendar rather than a process that takes most of a year. You do not simply leave. You build a case that you have left, and you start building it long before the moving truck arrives.
What California Can Still Tax After You Leave
This is the part that surprises most people. Moving to Texas or Florida does not mean California stops taxing the RSUs that your employer granted while you lived here. The state applies its own sourcing rules to equity compensation: RSUs granted while you were a California resident are treated as California-source income, and the state taxes the portion that vested during your California residency, regardless of where you live when they vest.
The same rule applies to stock options exercised after the move. If the grant date fell during your California residency, California claims a share of the gain. This is not negotiable and not something your new state can override.
There is more detail on how this works in our guide to RSU tax planning for California, including how the state's sourcing formula applies to grants that straddle your move.
The 12-Month Countdown: A Timeline for the Move
A well-planned move gives you time to establish ties to your new state and sever ties to California gradually. Here is what the timeline looks like.
The day count is critical. California uses a strict 183-day rule, and the FTB counts partial days as full days. Leave before midnight and that day counts. Fly back for a weekend and those days count too. Some executives keep a calendar log for the full year just to be safe.
Documentation wins every FTB audit. Keep flight itineraries, credit card statements, lease or purchase agreements, utility bills in your new address, and a signed affidavit from your employer confirming your first day of work in the new location. Without these, the FTB has little reason to believe you left at all.
Beyond Equity: What Else Changes When You Leave
If you own a business or rental property in California, the move introduces a second layer of planning.
For an S corp or multi-entity structure, relocating the business itself means considering new state registration, franchise tax obligations, and whether your entity choice still makes sense in a state without personal income tax. Our post on California capital gains tax strategies covers how the state taxes asset sales, including real estate held through an entity, when the owner has moved out of state.
For rental property you keep in California, Prop 13 protects your property tax basis, but the rental income is still California-source and you will file a non-resident return each year. A 1031 exchange on a San Diego rental property lets you defer capital gains tax if you sell and reinvest, even after you have moved.
The FTB Audit: Why It Happens and How to Win
The California Franchise Tax Board audits residency changes aggressively. When a high-income taxpayer files a part-year resident return and reports a sharp drop in California-source income, the FTB takes notice. They run a nine-factor test that weighs every tie you have, and they are particularly skeptical of moves to zero-tax states.
The factors are not mysterious. The FTB looks at where you spend time, where your family lives, where you are registered to vote, where you hold a driver's license, where your cars are registered, where you bank, where your professionals (doctors, dentists, attorneys) are located, where you belong to clubs and organizations, and where your personal property is kept. A clean break across all nine factors is the only defense that holds up.

What a Strategist Does That a Preparer Does Not
A tax preparer files your return in April based on what already happened. A tax strategist looks at the year ahead and designs the outcome before it is locked in. For a tech executive planning a move out of California, that distinction matters. Your preparer can tell you what you owe after you move. A strategist can help you decide when to move, how to structure the transition of your equity, and what documentation to keep so that what you owe is what the law actually requires, not what the FTB assumes when the records are unclear.
The difference between compliance and strategy is the difference between a surprise tax bill and a planned outcome. When strategies stack, they produce results that no single move can achieve on its own, and that is what year-round planning is built for.
FAQ
How are RSUs taxed in California?
California taxes RSUs as ordinary income at the time of vesting, at the state's regular income tax rates, which can reach 13.3%. If you were a California resident when the RSUs were granted, the state treats that portion of the income as California-source even if you live elsewhere when they vest.
How do I avoid getting double taxed on RSUs when moving out of California?
Double taxation happens when California taxes the income and your new state also claims it. Most states with no income tax, like Texas and Florida, do not tax wage income, so the risk is minimal. For moves to other states, a tax credit on your new state return usually offsets the California tax paid on the same income.
What is the 183-day rule for California residency?
California considers you a resident if you spend more than 182 days in the state during the tax year. Partial days count as full days. The day you leave and the day you return both count. Staying under 183 days is necessary but not sufficient; the FTB also evaluates your domicile and the nine-factor test.
What are the best tax strategies for high-net-worth individuals?
The most effective strategies combine several approaches: timing income and deductions across multiple years, choosing the right entity structure for any business you own, accelerating depreciation on real estate through a cost segregation study, and funding a defined benefit or cash balance plan far beyond what a standard 401(k) allows. A move out of California should be coordinated with all of them.
What is proactive tax planning?
Proactive tax planning means designing your tax outcome before the year closes rather than filing a return that simply reports what happened. It involves quarterly check-ins, scenario modeling, and strategic decisions about entity structure, retirement funding, and income timing that change the tax result itself.
Is it worth getting a tax advisor before moving out of California?
Yes. The cost of a miscalculated residency change can be hundreds of thousands of dollars in unexpected California tax, plus interest and penalties if the FTB audits you and determines you never actually left. A strategist who knows California's sourcing rules and the documentation standards the FTB applies is essential before making the move.
