Moving from Canada to California: The RRSP Problem, the 13.3% Rate, and What the Treaty Doesn't Cover

California is the state where the usual Canada-to-US script breaks. In most states the move is a rate cut and the RRSP rides along untouched. In California the combined top rate lands within a few points of Ontario's, the state does not recognize the Canada-US treaty, and it taxes the earnings inside your RRSP every year even though you have withdrawn nothing. The departure tax on the Canadian side still applies. The planning problem is different from Florida's: it is not when to leave, it is what to do with the RRSP before you do.

Key takeaways

• California's top rate is 13.3% (12.3% plus a 1% surcharge above $1 million), giving a combined top rate near 50.3%. Ontario, BC, and Quebec are all about 53.5%; Alberta is about 48%.
• California taxes capital gains as ordinary income. There is no preferential rate.
• California does not follow the treaty's RRSP deferral. The Franchise Tax Board taxes the RRSP's annual earnings as they accrue.
• Canada's departure tax applies on the way out regardless of destination.
• Property tax under Proposition 13 is about 1.1% of purchase price with a 2% annual cap; sales tax runs 8.75% to 10.25% in the major metros.

The Canadian departure

Departure tax is a deemed sale of non-registered investments, private company shares, crypto, and foreign property at fair market value on the day you leave. Canadian real estate, RRSPs, TFSAs, and pensions are excluded. Report on Form T1243, list holdings on Form T1161 if the total exceeds $25,000, and post security under Form T1244 to defer tax on illiquid assets.

Because California will tax post-arrival gains as ordinary income at rates up to 13.3% on top of federal, there is less reason than usual to defer realization: a gain realized before departure is taxed once in Canada at half inclusion; the same gain realized after arrival in California is taxed federally at preferential rates and by California at ordinary rates on the full amount, with the treaty's Article XIII(7) basis step-up available federally but not in California.

The RRSP in California

Federally, Article XVIII of the treaty defers US tax on RRSP growth until withdrawal, and the deferral is automatic. California does not conform. The Franchise Tax Board treats the RRSP as an ordinary investment account: interest, dividends, and realized gains inside it are taxable on the California return in the year earned, with no credit for Canadian tax because Canada charges none until withdrawal. When you eventually withdraw, California gives you basis for earnings it already taxed, but the annual drag while you live there is real.

The options, in order of how often we use them:

1. Convert to a RRIF and draw periodically while still a Canadian resident, if retirement is near, so less remains in the account when California starts counting.
2. Restructure holdings inside the RRSP toward assets that produce little annual taxable income (growth equities rather than bonds or dividend payers) so the California inclusion is small.
3. Collapse part or all of the RRSP before departure, paying Canadian tax at your marginal rate in the departure year, when that rate is lower than the combined future drag. This is the right answer more often than people expect for mid-sized accounts and lower departure-year income.
4. Accept the annual inclusion and track California basis carefully. Right for large accounts where the Canadian tax on a collapse would be prohibitive.

California's side

• Income tax. Ten brackets from 1% to 12.3%, plus the 1% Mental Health Services surcharge above $1 million. California taxes worldwide income of residents.
• Capital gains. Ordinary rates. No preferential treatment.
• Sales tax. 7.25% state base; 9.5% in Los Angeles County, 8.625% to 8.75% in San Francisco and the Peninsula, 10.25% in some LA-area cities.
• Property tax. Proposition 13 sets the assessed value at purchase price and limits increases to 2% a year; the effective rate is about 1.1% plus local bonds.
• Estate tax. None at the state level.
• Residency. California audits arrivals and departures; expect to document your residency start date.
• Community property. Assets acquired during marriage while resident are community property, which affects basis at death and division on divorce.

US federal side

Dual-status return in the arrival year, FBAR on Canadian accounts, Form 8938 above thresholds, and the RRSP deferral federally. The TFSA loses its tax-free status; close it before crossing. Equity compensation vesting after the move is split by working days between Canada and the US, and California sources its share by California working days as well.

Who moves to California

Tech workers to the Bay Area and Los Angeles, entertainment and VFX professionals to Los Angeles, biotech to San Diego and South San Francisco, and energy and clean-tech professionals from Alberta. The Vancouver-to-Bay-Area and Toronto-to-Los-Angeles paths are the busiest.

Worked example

A Toronto software engineer moves to San Francisco on July 1 with $300,000 of unrealized gain in a non-registered account, $600,000 in an RRSP producing about $18,000 a year of interest and dividends, and RSUs vesting after the move.

• Departure tax. $300,000 gain, $150,000 taxable, at about 53.5%: roughly $80,000.
• RRSP. Federally deferred. California taxes the $18,000 annual earnings at rates up to 13.3%: roughly $2,000 to $2,400 a year of drag on top of nothing federally. Restructuring the holdings toward growth equities cuts the inclusion.
• RSUs. Split by working days between Canada, US federal, and California.
• California. Salary taxed at combined rates approaching 50%. Sales tax 13% HST becomes 8.625%.

"When you leave Canada, you are considered to have sold certain types of property (even if you have not sold them) at their fair market value (FMV) and to have immediately reacquired them for the same amount. This is called a deemed disposition and you may have to report a capital gain (also known as departure tax)." — Canada Revenue Agency, Leaving Canada (emigrants), https://www.canada.ca/en/revenue-agency/services/tax/international-non-residents/individuals-leaving-entering-canada-non-residents/leaving-canada-emigrants.html

Practitioner note

The RRSP decision has to be made before the departure date, because every option except "accept the drag" requires you to still be a Canadian resident when you act. We run the four options against the client's account size, expected years in California, and departure-year income, and the answer is not always the one that minimizes tax this year.
