Here is a surprising comparison: California has the highest state income tax in the US (up to 13.3%), and when you add US federal tax, total Californians pay is remarkably similar to what Canadians pay. At $100,000 income, California state tax is $5,762 and US federal is ~$17,344, totalling $23,106. Canada (federal + Ontario provincial) totals $24,385 — just $1,279 more. At $150,000, total California (state + federal) is ~$40,524 versus Canada's $42,096 — still very close. On a state-only basis, California's $5,762 vs Canada's $24,385 makes Canada look far more expensive, but this comparison misses the full picture. Americans moving from California to Canada face the same US federal obligation in both locations — the real incremental cost is replacing state tax with Canadian taxes, which at these income levels is similar in total. The key advantage Canada offers: universal healthcare. The key disadvantage: Americans must continue filing US returns even after moving to Canada.

California state income tax ($5,762) is much lower than Canada's combined federal + Ontario provincial tax ($24,385) at $100,000. However, Californians also pay US federal (~$17,344), bringing total CA burden to ~$23,106 — remarkably close to Canada's $24,385. The state-only comparison understates the similarity.

Frequently Asked Questions

Q: Will I still pay US taxes if I move from California to Canada?

Yes. All US citizens and green card holders must file a US federal tax return regardless of where they live. Moving from California to Canada ends your California state tax obligation (once you establish non-residency from California — which requires careful planning given California's aggressive residency rules), but your US federal obligation continues. The US-Canada tax treaty and foreign tax credits typically prevent double taxation.

Q: How do total taxes compare when you include federal?

This is the surprising insight: California state + US federal at $100,000 is approximately $23,106, while Canada (federal + Ontario provincial) is $24,385. The difference is just $1,279 at $100K. At $150,000, total California ($40,524) vs Canada ($42,096) — a gap of only $1,572. California's state tax alone looks tiny compared to Canada, but once you add the US federal tax that both Californians and Canadian-based Americans owe, the comparison is much tighter.

Q: Does California try to tax you after you move to Canada?

California is notorious for pursuing former residents it considers to have not properly ended their California domicile. To break California tax residency, you must change your domicile, register to vote elsewhere, obtain a new driver's license, update professional licenses, and minimize time spent in California. The Franchise Tax Board has been known to audit high-income earners who claim to have moved. Working with a tax professional experienced in California exits is strongly recommended.

Q: Which is better for tech workers — California or Canada?

California (especially Silicon Valley) typically offers higher USD salaries for tech roles. At $200,000+ tech compensation, California state + federal is lower than Canada's combined rates in absolute dollars, making California more favorable on pure income retention. However, Canada offers universal healthcare, lower housing costs in cities like Toronto compared to San Francisco, and a different immigration pathway. Many tech workers find the lifestyle and career tradeoffs more important than the marginal tax difference.

Q: Does Canada have healthcare included in taxes?

Yes. Canada's universal Medicare system provides basic healthcare coverage funded through general taxation. This is a significant benefit compared to California, where individuals typically pay $500-$1,000+/month in private health insurance premiums. When factoring healthcare costs, the total cost-of-living comparison between California and Canada shifts meaningfully.

Q: What are FBAR requirements for Americans living in Canada?

Americans with Canadian bank accounts totalling over $10,000 USD equivalent must file FBAR (FinCEN Form 114) annually. RRSP accounts (Canadian retirement accounts) have special IRS reporting requirements under Form 8891 (now folded into Form 3520). Greenback Expat Tax Services handles these complex filings and specialises in the full US expat return for Canada-based Americans.

Q: How does Canadian healthcare compare to California health insurance?

Canadian universal healthcare covers most medical services at no direct cost to residents. California residents without employer coverage pay significant premiums — average individual health insurance costs $500-$800/month on Covered California. For a California resident spending $8,400/year on health insurance who moves to Canada, the 'tax savings' from universal healthcare is substantial, partially offsetting Canada's higher income tax.
