California's Billionaires Are Leaving California. Should You?

Disclaimer: This article is for educational purposes only and does not constitute tax, legal, or financial advice. California residency law is complex and fact-specific. Consult a qualified tax professional or attorney before making residency decisions.

In January 2026, Google co-founder Larry Page quietly purchased two Miami mansions for a combined $173 million. Around the same time, Sergey Brin dissolved or relocated at least 15 California-based LLCs, re-registering seven of them in Nevada. Peter Thiel's investment firm, Thiel Capital, signed a lease for a new office in Miami's Wynwood district on New Year's Eve.

Three of the wealthiest people in American history made the same move at the same time. That's not coincidence. That's strategy.

The catalyst? California's proposed Billionaire Tax Act, a ballot initiative that would impose a one-time 5% excise tax on residents with a net worth exceeding $1 billion. For Page and Brin, whose combined net worth exceeds $518 billion, the math is straightforward: stay in California and owe roughly $26 billion in state taxes, or establish residency elsewhere and owe nothing.

But here's what most people miss: the legal framework these billionaires are using to leave California is the same one available to anyone earning $75,000 or more. The difference is scale, not method. The steps are identical whether your net worth is $518 billion or $518,000.

If you're a remote worker, digital nomad, travel nurse, retiree, or business owner paying California's 13.3% top income tax rate, this guide breaks down exactly what Page, Brin, and Thiel are doing — and how you can do the same thing for a fraction of the cost.

What California Takes From You Every Year

California has the highest state income tax rate in the nation. The top marginal rate hits 13.3% on income over $1 million, but even mid-range earners feel the weight. Here's what California's income tax costs at different income levels compared to Florida, which charges zero state income tax:

Your Annual Income	California State Tax (Effective Rate)	Florida State Tax	Your Annual Savings
$75,000	~$3,375 (4.5%)	$0	$3,375
$150,000	~$9,827 (6.55%)	$0	$9,827
$300,000	~$25,499 (8.5%)	$0	$25,499
$500,000	~$48,574 (9.7%)	$0	$48,574
$1,000,000+	~$123,100+ (12.3%+)	$0	$123,100+

Put another way: if you earn $300,000 in California, you work until approximately April 15th just to cover your state income tax. In Florida, that money is yours from January 1st.

Over five years, a $300,000 earner saves $127,495 by establishing Florida residency. Over ten years, that's a quarter of a million dollars. These aren't theoretical numbers. This is money that stays in your pocket — or doesn't.

Your Tax Base offers Florida residency plans starting at $55/month that include a real Florida residential address, tax compliance monitoring, and access to licensed CPAs.

Why the Billionaires Are Moving Now (and Why You Should Too)

The urgency isn't just about the Billionaire Tax Act. Three things are happening simultaneously that make 2026 the most important year to establish residency outside California:

1. The FTB is hiring aggressively

California's Franchise Tax Board increased compliance audit staff by 30% in 2025. The FTB's audit rate for targeted noncompliance cases now exceeds the IRS audit rate by more than 2x, particularly for higher-income brackets in real estate, tech, and business ownership. More auditors means more audits. The window to make a clean exit gets smaller every year.

2. The proposed wealth tax has no exit provision

Unlike a standard income tax, the Billionaire Tax Act would apply to residents as of January 1, 2026. That date has already passed. If you were a California resident on that date and the measure passes, you could owe the tax regardless of where you move afterward. The initiative's backers have already collected 25% of the required 874,641 signatures to qualify for the November 2026 ballot. While this specific measure targets billionaires, it sets a precedent. If a 5% wealth tax passes for billionaires today, a lower threshold could follow for millionaires tomorrow.

3. Remote work has eliminated the last excuse

Before 2020, leaving California often meant leaving your job. That's no longer true. Remote work policies are permanent at most major employers. If your job doesn't require you to physically be in California, your only reason for paying 13.3% in state income tax is inertia.

How Page, Brin, and Thiel Are Actually Doing It

The media focuses on mansion purchases and LLC dissolutions, but the actual legal strategy behind every successful California exit follows the same three-phase process, whether you're worth $173 billion or $173,000.

Phase 1: Establish a New Domicile

Domicile is the legal term for your permanent home — the place you intend to return to when you're away. California can only tax you as a resident if you're domiciled there. Changing your domicile requires two things: physical presence in your new state and the intent to make it your permanent home.

Larry Page did this by purchasing real estate in Miami. But you don't need to buy a mansion. You need a legitimate Florida residential address that satisfies domicile requirements.

This is where most people make their first mistake. A P.O. box doesn't count. A virtual mailbox alone may not satisfy all requirements. The Florida Declaration of Domicile (required to formally establish Florida as your legal home) requires a residential address, and so does a Florida driver's license.

Your Tax Base provides a real Florida residential address included with every plan. This address satisfies Declaration of Domicile requirements, Florida driver's license applications, and voter registration. It's the same type of documented address that establishes legal presence in the state.

Phase 2: Sever Ties With California

Establishing a new domicile is only half the equation. The FTB uses a 19-factor test (documented in their own Residency and Sourcing Technical Manual) to determine whether you've genuinely left California. If too many factors still point to California, the FTB will argue you never really left — regardless of what your driver's license says.

Strongest factors (the FTB cares about these the most):

• Where you maintain your primary residence
• Where your spouse and dependents live
• Where you're registered to vote

Moderate factors:

• Where your vehicles are registered
• Where you maintain bank accounts
• Where your professional licenses are active
• Where you receive mail

"Soft ties" that still trigger audits:

• Active California gym memberships
• California medical and dental providers
• Storage units in California
• California club or organization memberships
• California professional or religious affiliations

That last category surprises people, but it shouldn't. The FTB has been known to subpoena dental records, gym membership logs, and country club attendance to prove a taxpayer maintained closer ties to California than they claimed. This is documented in the FTB's own technical manual. They're not bluffing.

Peter Thiel's approach was systematic: Thiel Capital opened a physical office in Miami, establishing business presence outside California. Brin went further, dissolving entities tied to everything from his superyacht to a private air terminal at San Jose airport. They're not just moving. They're methodically severing every provable connection.

You should do the same: close California bank accounts, transfer vehicle registrations, update your voter registration, move professional licenses, change your address with every financial institution, cancel California subscriptions and memberships, and establish equivalent ties in Florida.

Your Tax Base's compliance monitoring service tracks your state ties and flags anything the FTB could use against you in an audit. Plans with compliance monitoring start at $90/month.

Phase 3: Document Everything

The FTB has four years from the later of your filing date or the return due date to initiate a residency audit. That means every day you spend in each state, every transaction, every piece of mail matters for at least four years after you leave.

What to document:

• Days in each state. Track them meticulously. Calendar apps, travel receipts, credit card statements, and cell phone location data all count as evidence. The FTB will use your own data against you if it helps their case — so make sure it helps yours instead.
• Financial transactions by state. Where you spend money tells a story. Make sure the story says "Florida resident."
• Official address changes. Keep dated copies of every address change: IRS Form 8822, USPS change of address, bank statements, insurance policies, everything.
• Florida Declaration of Domicile. File this with the clerk of the circuit court in your Florida county. It's a sworn statement of your intent to make Florida your permanent home. It's not required by law, but it's powerful evidence in an audit.

The IRS Tax Home Test: A Second Layer Most People Forget

State domicile is one issue. Your IRS tax home is another. The IRS defines your tax home as your "regular place of business or post of duty" — essentially where you earn your money. If you're a W-2 remote worker, this is relatively simple. But if you're a travel nurse, contractor, or someone who works in multiple states, the IRS applies a three-factor test:

1. Where is your main place of business? (primary factor)
2. Where do you spend the most working time?
3. Where do you have the strongest historical financial ties?

If you don't have a tax home (common for travel nurses and full-time travelers), you're considered an "itinerant" worker. Itinerant status means you cannot deduct travel expenses. For a travel nurse earning $120,000 with $30,000 in travel-related expenses, losing that deduction costs thousands in additional federal taxes every year.

Establishing a legitimate Florida address and maintaining documented ties to a fixed location solves this. It gives you a tax home that satisfies IRS requirements while simultaneously establishing your Florida domicile.

This is exactly why travel nurses and digital nomads use Your Tax Base. A Florida residential address + tax compliance monitoring gives you both a state domicile and an IRS tax home in one package. Get started for $55/month.

The Myth That Gets People Audited: The 183-Day Rule

Most people believe the "rule" is simple: spend fewer than 183 days in California and you're safe. This is dangerously wrong.

The 183-day safe harbor provision (California Revenue and Taxation Code Section 17016) only applies to people who are already classified as non-residents. It is not a residency test. It's a protection for people who have already established domicile elsewhere.

Here's what that means in practice:

• You can spend zero days in California and still owe California taxes if you haven't properly changed your domicile. If the FTB determines your intent was to remain a Californian (based on the 19-factor test), the number of days you spent there is irrelevant.
• You can spend more than 183 days in California and still qualify as a non-resident if you meet the safe harbor conditions: you're in California for a temporary or transitory purpose, and you maintain a permanent home outside the state.

The billionaires understand this. That's why Page bought mansions in Miami rather than simply spending fewer days in San Francisco. Physical presence matters, but documented intent matters more.

Does California Have an Exit Tax?

Not yet. California does not currently impose a departure or exit tax on residents who leave. However, the proposed Billionaire Tax Act functions similarly for those it targets: it applies based on residency status as of January 1, 2026, regardless of subsequent moves.

For everyone else, the risk isn't an exit tax. The risk is a residency audit where the FTB argues you never actually left. The result is the same: you owe California income tax on your worldwide income, plus penalties and interest, sometimes stretching back multiple years.

The best defense against this is a clean, well-documented exit. Every step matters. Every tie you leave uncut is ammunition for the FTB.

Your California Exit Checklist

Whether you're a billionaire or a $100K remote worker, the process is the same:

• Establish a Florida residential address (not a P.O. box)
• File a Florida Declaration of Domicile with your county clerk
• Obtain a Florida driver's license (surrender your CA license)
• Register to vote in Florida
• Register vehicles in Florida
• Open bank accounts with your Florida address
• Update your address with the IRS (Form 8822)
• Notify your employer of your new state of residence
• Transfer professional licenses to Florida (if applicable)
• Update all insurance policies to your Florida address
• Close or transfer California financial accounts
• Cancel California gym memberships, clubs, subscriptions
• Find new medical and dental providers in Florida (or telehealth)
• File a USPS change of address
• Begin tracking days spent in each state (maintain for 4+ years)
• File a California part-year return (Form 540NR) for the year you leave
• Keep all documentation for a minimum of four years after departure

The Bottom Line

Larry Page spent $173 million on Miami real estate. Peter Thiel opened a new office in Wynwood. Sergey Brin dissolved 15 LLCs. They did all of this for the same reason: California's tax environment has become untenable, and the legal path to leave is clear and well-established.

You don't need $173 million. You need a Florida residential address, a documented intent to stay, and a systematic plan to sever your California ties. The legal framework is the same at every income level.

The FTB is hiring more auditors. The proposed wealth tax is advancing. The window for a clean California exit is open right now, but it won't stay open forever.

Frequently Asked Questions

How much does it cost to establish Florida residency?

The state filing fees are minimal (Declaration of Domicile costs around $10, a new driver's license is about $48). The real cost is in setting up a legitimate residential address and ensuring ongoing compliance. Your Tax Base plans start at $55/month and include a residential address, virtual mailbox, and CPA access.

How long does it take to fully exit California?

The process itself can be completed in 30-60 days. However, you should maintain meticulous documentation for at least four years after leaving, as the FTB's statute of limitations for residency audits extends that long.

Can I keep property in California after I leave?

Technically yes, but it's the single biggest residency audit trigger. If you maintain a home in California, the FTB will argue it's your "primary residence." If you must keep California property, rent it out and never stay there. Document everything.

Will California tax my retirement income if I move to Florida?

No. Under federal law (4 U.S.C. Section 114), states cannot tax retirement income of non-residents. Once you've established Florida domicile, California cannot tax your pension, 401(k) distributions, or IRA withdrawals.

What if I work remotely for a California employer?

If you've established domicile in Florida and perform your work from Florida, your income is Florida-sourced (meaning no state income tax). However, if you travel to California for work, the days spent working in California may be subject to California income tax. Track your days carefully.

Does California have an exit tax?

No. California does not currently have an exit tax. The proposed Billionaire Tax Act (2026 ballot initiative) would function as a one-time wealth tax for residents as of January 1, 2026, with a net worth over $1 billion. It has not yet qualified for the ballot.

What triggers an FTB residency audit?

Common triggers include: filing a part-year return with high income, maintaining a California home while claiming non-resident status, keeping California professional licenses active, large capital gains events (stock sales, business exits), and inconsistent information across state and federal returns.

Is a virtual mailbox enough to establish Florida residency?

A virtual mailbox alone may not satisfy all domicile requirements. The Florida Declaration of Domicile and driver's license both require a residential address. Your Tax Base provides a real Florida residential address alongside virtual mailbox services to ensure your domicile is properly established.
