Leaving California is its own financial event.
Most Americans moving to Canada have one tax system to leave and one to enter. Californians have three. The Franchise Tax Board does not let go easily, it keeps taxing certain income after you’re gone, and community property changes how your accounts are treated on both sides of the border. This guide covers the California-specific layer. For everything every American faces — 401(k)s, Roth IRAs, PFICs, FBAR — the national guide is the companion piece.

Three things a Texan or Floridian never has to think about.
Residency doesn’t end when you leave
California decides whether you’re still a resident by looking at where your life is anchored — home, family, licenses, doctors, bank accounts, the lot. Move to Vancouver but keep a house in Palo Alto and a California driver’s license, and the FTB has a case that you never left.
Some income stays Californian after you go
Equity compensation earned while you worked in California is California-sourced when it vests or is exercised, even if you’re a Canadian resident by then. Rental income from a California property and California-source business income follow the same logic.
Community property crosses the border with you
Married Californians own most of what they acquired during the marriage 50/50 by law. Canada has no equivalent concept. How each spouse’s half is treated for Canadian tax, U.S. estate tax and attribution rules needs deciding — ideally before the move, not after.
Terminating California residency: the high-stakes first step.
California taxes residents on worldwide income at the highest state rate in the country — a nine-bracket schedule topping out at 12.3%, plus a further 1% on taxable income above $1 million, per the California Tax Rate Schedules published by the Franchise Tax Board. It also has a reputation, earned over decades of audits, for pursuing people who moved away on paper but not in substance. The test is not a day count. It is a weighing of where your closest connections are, and the burden of proving you left is on you. The FTB sets out the framework in its guidance on part-year resident and nonresident status.
That means a clean departure is a project with a date attached. You want the day you stop being a California resident to be the same day, or earlier than, the day you become a Canadian tax resident — no gap where you are resident in both, and no gap where you are resident in neither and Canada’s departure rules and California’s residency rules argue about your capital gains.
The things that keep you Californian are mundane: a home you still own and can return to, a spouse or minor children who stay behind, a California driver’s license and voter registration, professional licenses, the family doctor and dentist, the bank branch, the storage unit, the country club. None of them alone is fatal. Together they are how audits are lost.
The things that prove you left are equally mundane, and they need to be dated: a lease or purchase in Canada, Canadian bank accounts and credit cards, a provincial driver’s license and health-card application, updated addresses on every U.S. account, resignation from California boards and memberships, and a part-year California return that draws a hard line under your last resident day.
Also on the list: if you were a green-card holder rather than a citizen, or you may eventually give up citizenship, the state-level exit and the federal U.S. exit tax are separate questions with separate timelines. Don’t let a clean California departure create a messy federal one.
Eight things to do, in this order.
Each one is either dated evidence that you left, or a decision that gets more expensive after your residency date.
Fix the dates
Choose your last California day and your first Canadian residency day, and make them the same. Everything below is timed against them. Our guide to when an American becomes a Canadian tax resident covers the Canadian side.
Decide what happens to the house
Sell before you leave, sell after, or rent it out. Each has a different California, federal and Canadian consequence. Renting is the choice that most often keeps people Californian. Which of the three is right depends on your basis, your timeline and how the rest of your departure looks — it’s the first thing we work through. See “Your California home” below.
Map your equity compensation
List every unvested RSU grant, unexercised option and deferred-comp balance with grant dates and vest dates. California will claim its share of anything earned there; Canada will tax it as employment income when it vests. Both can be true at once.
Settle the U.S. account decisions while you’re still a U.S. resident
Roth conversions, 401(k) consolidation, harvesting gains or losses — the moves covered in the national retirement-accounts guide. A Roth conversion done as a California resident is also taxed by California, so the sequencing has a state layer too. The order of these against your residency dates is where most of the money is saved or lost.
Document fair market value on arrival day
Canada treats you as having acquired everything you own at its value on your residency date. California and the IRS keep your original basis. Three different gain numbers on the same sale is normal — but only if you have the day-one valuation.
Cut the California anchors
Driver’s license, voter registration, professional licenses, club memberships, doctors, bank branch. Move or close each one and keep the paperwork. This is the file you hand to whoever defends your position later.
Sort community property before the border
Decide which spouse owns what, and whether a transmutation agreement or retitling makes sense, while California law still governs. See the community-property section below.
File the part-year return and stop
Your final California return is a part-year return through your last resident day, plus nonresident returns in later years only if you still have California-source income. If you’ve done the steps above, that’s usually just the equity compensation until it runs out.
Income California keeps taxing after you leave.
The rule is source, not residence. If the income was earned in California, or comes from California property, California taxes it regardless of where you live when you receive it. For most people leaving for Canada, that comes down to four things.
| What | California’s position | What Canada does | What to plan |
|---|---|---|---|
| RSUs and stock options | The portion earned during California workdays is California-sourced at vest or exercise, allocated by time worked in the state — the method set out in FTB Publication 1004, Equity-Based Compensation Guidelines. | Taxes the full benefit as employment income when it vests or is exercised while you’re resident. | Build the grant-by-grant map before the move. Foreign tax credits are how the two are reconciled. Cross-border stock options guide |
| Deferred compensation | Generally California-sourced to the extent earned there, with federal law limiting states’ reach on certain periodic retirement payments. | Taxable when received as a resident. | Ask how each plan pays out. Lump sums and installment schedules are treated differently. |
| A California rental | Rental income and eventual sale gain are California-sourced. A nonresident sale is subject to withholding of 3 1/3% of the sales price at closing unless an exemption or the alternative calculation applies — see the Instructions for Form 593, Real Estate Withholding. | Reports the same income; credits the U.S. and California tax paid. | Renting the home is often what keeps a departure from being clean. Weigh the income against the audit exposure. |
| Business income | Income from a business, partnership or S-corp with California operations is apportioned to California. | Taxes worldwide income once you’re resident, including your share of U.S. entities — with structuring consequences. | Entity choice that worked in California can be wrong in Canada. Review before, not after. |
What is not on the list: your 401(k), IRA and Roth. Federal law — 4 U.S.C. §114 — bars any state from taxing the retirement income of a nonresident, and the definition covers qualified plans: 401(a) trusts, SEPs, 403(a) and 403(b) plans, IRAs, 457 and governmental plans. Certain nonqualified deferred compensation also qualifies, but only where it is paid in substantially equal periodic payments over life expectancy or at least ten years — which is why deferred comp sits in the table above and your 401(k) does not. Once you have left cleanly, those qualified accounts belong to the IRS and the CRA only. That is the national guide’s territory.
Your California home: sell, rent, or hold.
Californians arrive at this decision with two things other Americans don’t have: a Prop 13 property-tax basis that may be a fraction of what a new buyer would pay, and the largest untaxed gain on a primary residence most households will ever see. Both push toward holding. Both need to be weighed against what holding does to your residency position.
Selling before you leave is the simplest. You use the federal primary-residence exclusion — up to $250,000 of gain for a single filer, $500,000 on a joint return, if you have owned and lived in the home for at least two of the five years before the sale, per IRS Topic no. 701, Sale of your home — as a U.S. resident, California taxes the gain above it as part of your final resident year, and Canada has no claim because you weren’t resident yet. The house is gone from the closest-connections analysis.
Selling after you leave keeps the federal exclusion available as long as you still meet that two-of-five-year test, but the gain above it is now California-sourced nonresident income with 3 1/3% withheld at closing, and Canada sees a sale of property acquired — for its purposes — at its value on your arrival day. If the market moved between arrival and sale, Canada taxes that piece. Timing the sale close to the move keeps the Canadian slice small.
Renting it out gives you income and preserves the Prop 13 basis, and it is the single most common reason a California departure is challenged. A home you can return to is the strongest connection there is. If you rent, the rest of the file has to be spotless.
On the Canadian side, the home you buy next qualifies for the principal residence exemption from day one — but to the IRS it’s just a house, and the gain above the federal exclusion is taxable when you eventually sell. Buying property in Canada as an American covers that purchase.
Community property meets a country that doesn’t have it.
In California, most property acquired during a marriage belongs to both spouses equally, regardless of whose name is on the account. Canada’s provinces have family-law rules for what happens on separation or death, but for income tax each spouse is taxed on what they legally own and earn, and money moved between spouses triggers attribution rules that send the income back to whoever supplied the funds.
That creates three questions. First, how does the CRA see a California brokerage account titled in one spouse’s name but owned 50/50 under community property — and will it accept splitting the income? Second, for U.S. estate tax, community property gets a full basis step-up on the first death — the entire property, not just the deceased spouse’s half, is revalued under IRC §1014(b)(6), as IRS Publication 555, Community Property explains — which is valuable and easy to lose if assets are retitled carelessly on the way north. Third, if one spouse is a U.S. citizen and the other isn’t, the estate and gift rules between them are already restrictive, and community property adds a layer.
None of this is a reason to panic. It is a reason to have an estate attorney and a cross-border planner look at how things are titled before you cross, while California law still governs the answer. Retitling, a transmutation agreement, or simply documenting the community character of each asset can each be right depending on the couple. Our estate-exposure check is a five-minute first pass.
The rest is the same for every American heading north.
Your 401(k), your Roth, the PFIC problem, the TFSA question, FBAR and dual filing don’t care which state you left. They’re covered once, properly, in the national guide.

What Californians ask before they move.
If I move to Canada, does California stop taxing me?
On your worldwide income, yes — once you’ve actually terminated residency, which California judges by where your closest connections are rather than by a day count. On California-source income (equity compensation earned there, a California rental, California business income), no. That income stays taxable in California as a nonresident.
Does California tax my 401(k) or IRA withdrawals after I leave?
No. 4 U.S.C. §114 bars any state from taxing the retirement income of a nonresident, and the definition covers qualified plans — 401(a) trusts, SEPs, 403(a) and 403(b) plans, IRAs, 457 and governmental plans. Once you have cleanly left, those distributions are a matter between you, the IRS and the CRA. Nonqualified deferred compensation is treated differently: it is protected only where it is paid in substantially equal periodic payments over life expectancy or at least ten years.
What about my unvested RSUs?
The share earned while you worked in California is California-sourced when it vests, even if you live in Canada by then; FTB Publication 1004 sets out the workday allocation method. Canada taxes the same vest as employment income. Foreign tax credits reconcile the two, but only if the allocation is tracked from the start. Map every grant before you move.
Can I keep my California house as a rental?
You can, and many people do. Understand that a home you can return to is the strongest single connection to California, so the rest of your departure has to be unambiguous. The rental income and eventual sale gain remain California-source, a nonresident sale carries 3 1/3% withholding at closing under the Form 593 rules, and Canada will also tax the income and any gain accruing after your arrival.
Should I do a Roth conversion before I leave California, or after?
A conversion while you are still a California resident is taxed by the IRS and by California. Once you are a Canadian resident, a conversion is generally taxable in Canada too, and contributing to or converting into a Roth after that point can compromise the treaty election that keeps the account tax-free in Canada. Which side of your residency date a conversion belongs on depends on your bracket in each country and on how much room you have before the move. It is worth modeling rather than guessing.
Does community property matter once we live in Canada?
Yes, in two ways. The CRA taxes each spouse on what they own, so how community assets are recognized affects who reports the income. And for U.S. estate tax, both halves of community property step up to fair market value on the first death under IRC §1014(b)(6) — see IRS Publication 555 — which is valuable and easy to lose by retitling on the way out. Get advice while California law still governs.
Will California audit me for leaving?
Residency audits are a real risk for higher-income departures, especially where a home is kept or income remains California-sourced. Audits are won on dated evidence: the lease or purchase in Canada, the license and health-card applications, the closed accounts, the part-year return. The checklist above is that evidence.
I’m a green-card holder, not a citizen. Anything different?
The California analysis is the same. Federally, a long-term green-card holder who gives up the card can trigger the U.S. exit tax, which is a separate decision with its own timeline. Read the exit-tax guide before surrendering anything.
