Quebec to California: The RRSP Gets Hit From Both Sides

Montreal's AI, gaming, and VFX sectors send a steady stream of talent to the Bay Area and Los Angeles, and the tax picture is the least favourable of any Quebec exit. Quebec's combined top rate is about 53.3%; California's combined federal and state rate is about 50.3%, with capital gains at ordinary rates and the RRSP taxed annually. The departure year runs through Revenu Québec, the CRA, and the IRS, and then the Franchise Tax Board starts.

Key takeaways

• Two Canadian departure returns: the federal T1 and Revenu Québec's TP-1, with matching departure dates.
• Quebec's roughly 53.3% top rate sets the departure tax. On a $300,000 unrealized gain, about $80,000.
• California's combined top rate is about 50.3%; capital gains at ordinary rates.
• California does not follow the treaty on RRSPs: the account's annual earnings are taxable on the California return.
• Quebec's 14.975% combined GST and QST becomes 8.625% to 10.25% sales tax. RAMQ ends on departure.

The three-authority departure

The federal deemed disposition applies to non-registered investments, private company shares, crypto, and property outside Canada; Quebec mirrors it. Report on federal Form T1243 (with T1161 for the property list if it exceeds $25,000) and on the Quebec equivalents. The 16.5% Quebec abatement is built into the 53.3% combined rate.

Because California taxes post-arrival gains at ordinary rates on the full amount, realizing gains before departure at Quebec's half inclusion is often cheaper than carrying them into California, even at 53.3%.

RAMQ ends when you leave Quebec to settle outside Canada. QPP paid later to a California resident is taxable only in the US under the treaty (California follows federal treatment of Social Security-type benefits).

The RRSP decision

Federally the RRSP is deferred under Article XVIII of the treaty. California does not conform: the Franchise Tax Board taxes the interest, dividends, and realized gains inside the account each year. Before departure, restructure toward growth assets that produce little annual income, draw the account down while still a Quebec resident, or accept the annual California inclusion and track basis. For Montreal tech movers with mid-sized RRSPs, restructuring is usual.

California's side

Graduated rates to 12.3% plus a 1% surcharge above $1 million; capital gains at ordinary rates; sales tax 8.625% in San Francisco, 9.5% in Los Angeles County; Proposition 13 property tax at about 1.1% of purchase price with a 2% annual cap; no estate tax; aggressive residency audits; community property. Los Angeles adds a gross receipts business tax that catches freelancers in entertainment from the first dollar.

Who makes this move

Montreal AI researchers to the Bay Area, Montreal gaming and VFX artists to Los Angeles, Quebec aerospace engineers to Southern California's defence and space sector, and Montreal biotech to San Diego.

Worked example

A Montreal VFX supervisor moves to Los Angeles on July 1 with $250,000 of unrealized gain in a non-registered account, $400,000 in an RRSP producing about $12,000 a year of income, and a Plateau condo sold in the departure year.

• Departure tax. $250,000 gain, $125,000 taxable, at about 53.3%: roughly $67,000 across the T1 and TP-1. Cheaper than California's ordinary-rate treatment later.
• RRSP. Federally deferred. California taxes the $12,000 annual income at rates up to 13.3%; restructuring reduces it.
• Condo. Sold as a resident under the principal residence exemption on both returns.
• California. Combined top rate about 50.3%. Sales tax 14.975% becomes 9.5%.

"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

Quebec-to-California is the file where the departure date carries the most weight, because it fixes the T1, the TP-1, the RRSP restructuring window, and the California residency start all at once. We set the date last, after the RRSP and gain decisions are made.
