Alberta to California: The Rare Corridor Where Your Tax Bill Goes Up

Most Alberta exits are a tax cut. California breaks the pattern. Alberta's combined top rate is about 48%, the lowest in Canada. California's combined federal and state top rate is about 50.3%, capital gains are taxed as ordinary income, and the state taxes RRSP earnings every year. For a Calgary energy engineer moving into the Bay Area's climate-tech sector or an Edmonton developer moving to Los Angeles, the income tax rate can rise, and the RRSP acquires an annual cost it never had.

Key takeaways

• Alberta's roughly 48% top rate sets the departure tax. On a $300,000 unrealized gain, about $72,000.
• California's combined top rate is about 50.3%, and its rates on capital gains are ordinary rates.
• California does not follow the treaty on RRSPs: the account's annual earnings are taxable on the California return.
• Alberta's 5% GST becomes 8.625% to 10.25% sales tax in the major California metros.
• AHCIP ends on permanent departure.

The Alberta departure

Departure tax applies to non-registered investments, private company shares, crypto, and foreign property at fair market value on the departure date. Alberta 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.

Because California will tax post-arrival gains at ordinary rates on the full amount, there is a case for realizing gains before departure while Alberta taxes them at half inclusion and 48%. A Calgary corporation is deemed sold, loses CCPC status, and becomes a US controlled foreign corporation with Form 5471 filings; wind it up before you go.

The RRSP decision

Federally the RRSP is deferred under Article XVIII of the treaty. California does not conform, and the Franchise Tax Board taxes the interest, dividends, and realized gains inside the account each year. Before the departure date, the choices are to restructure the holdings toward growth assets that throw off little annual income, to draw the account down while still an Alberta resident at Alberta rates, or to accept the annual California inclusion and track basis. For a mid-sized RRSP and a low departure-year income, a partial collapse in Alberta is often cheaper than years of California drag.

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, up to 10.25% in some cities; Proposition 13 property tax at about 1.1% of purchase price with a 2% annual cap; no estate tax; aggressive residency audits; community property.

Who makes this move

Calgary energy engineers into Bay Area climate-tech and energy-transition firms, Edmonton and Calgary software developers into Los Angeles and the Bay Area, and Alberta clean-energy professionals into California's utility and storage sector.

Worked example

A Calgary engineer moves to San Jose on June 30 with $250,000 of unrealized gain in a non-registered account, $500,000 in an RRSP producing about $15,000 a year of income, and a professional corporation wound up before departure.

• Departure tax. $250,000 gain, $125,000 taxable, at about 48%: roughly $60,000.
• RRSP. Federally deferred. California taxes the $15,000 annual income at rates up to 13.3%: roughly $1,500 to $2,000 a year. Restructuring toward growth equities reduces it.
• Corporation. Capital dividend account paid and wound up as an Alberta resident.
• California. Salary taxed at combined rates approaching 50%, a slight increase from Alberta. GST 5% becomes sales tax 9.375%.

"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

Alberta-to-California is the file where we most often recommend paying more Canadian tax on purpose: realizing gains and drawing down the RRSP in Alberta at 48% and half inclusion, rather than carrying them into a state that taxes gains at ordinary rates and RRSP earnings annually. The math depends on years in California and the account size, and we run it before the date is set.
