Vancouver to San Francisco: The RRSP Trap and the Bay Area's Cost Layers

Vancouver to the Bay Area is a tech corridor with a lateral tax move: BC's combined top rate of about 53.5% becomes about 50.3% in California. The differences are the RRSP, which California taxes annually, RSUs sourced three ways, and a Vancouver home that faces three vacancy taxes if kept empty.

Key takeaways

• BC's roughly 53.5% 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.
• BC's 12% combined GST and PST becomes 8.625% sales tax in San Francisco.
• A Vancouver home kept empty faces three vacancy taxes. MSP ends on permanent departure.

The BC departure

Departure tax applies to non-registered investments, private company shares, crypto, and foreign property at fair market value on the departure date. BC 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 for illiquid assets. The Vancouver home is excluded, but kept empty it invites BC's Speculation and Vacancy Tax, Vancouver's Empty Homes Tax, and the federal Underused Housing Tax; rent it under NR6 and Section 216, or sell in the departure year. MSP ends on permanent departure.

San Francisco's side

Graduated California state rates to 12.3% plus a 1% surcharge above $1 million, for a combined federal and state top rate near 50.3%; capital gains taxed as ordinary income; 8.625% sales tax in San Francisco, 9.125% to 9.375% on the Peninsula and in the South Bay; Proposition 13 property tax at about 1.1% of purchase price with a 2% annual cap; no estate tax; aggressive residency audits; community property.

The RRSP in California

Federally 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 Canadian resident, or accept the annual inclusion and track California basis.

RSUs and California sourcing

RSUs granted in Canada that vest after the move are split between Canada and the US by working days over the vesting period, and California sources its share by California working days as well. Both payrolls may withhold on the full amount. Because California taxes the gain on a later sale at ordinary rates, the decision to hold or sell vested shares is a California decision as much as a federal one.

Who makes this move

Vancouver software engineers to the Bay Area's technology companies, BC founders relocating startups to the Bay Area, Vancouver AI researchers to the region's AI labs, and BC biotech researchers to South San Francisco's life sciences cluster.

Worked example

A Vancouver software engineer moves to San Francisco 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, RSUs vesting after the move, and a Vancouver condo sold in the departure year.

• Departure tax. $250,000 gain, $125,000 taxable, at about 53.5%: roughly $67,000. Cheaper than California's ordinary-rate treatment later.
• RRSP. Federally deferred. California taxes the $12,000 annual income; restructuring reduces it.
• RSUs. Split by working days between Canada, US federal, and California.
• Condo. Sold as a resident under the principal residence exemption. No vacancy taxes.
• San Francisco. Combined top rate about 50.3%. Sales tax 12% becomes 8.625%.

Official sources

"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

California does not conform to federal tax treaty provisions; income excluded from federal income under a treaty may be taxable by California. — California Franchise Tax Board, Publication 1031, Guidelines for Determining Resident Status, https://www.ftb.ca.gov/forms/2025/2025-1031-publication.pdf

The speculation and vacancy tax is an annual tax based on how owners use residential properties in areas in B.C. affected most by the current housing shortage crisis. — Government of British Columbia, Speculation and vacancy tax, https://www2.gov.bc.ca/gov/content/taxes/speculation-vacancy-tax

Practitioner note

Vancouver-to-Bay Area founders sometimes move in the window between a funding round and a liquidity event, when the departure-date valuation is defensible and the deemed gain is smaller than it will be later. We get the valuation, file T1244, and make the Article XIII(7) election on the first US return.
