Is the US or Canada a lower-tax country?

Federal-only, the US is lower at most working incomes — its standard deduction ($16,100 single, 2026) and 10%/12% lower brackets beat Canada's 15% federal rate from $16,129. Adding state/provincial: at $100,000 gross, US federal-only take-home is $79,180 (79.2% net) versus CA Ontario take-home $74,639 (74.6% net). The US lead widens once you live in a no-tax state (TX, FL, NV, WA) and narrows in CA/NY. Canada's lead is in healthcare, paid leave, and lower out-of-pocket costs — not direct tax.

How does a US 401(k) compare to a Canadian RRSP?

Both are tax-deferred retirement vehicles with employer matching common but not mandatory. US 401(k) limit 2026: $23,500 (estimated, indexed) employee + $7,500 catch-up if 50+; total including employer match $70,000. Canadian RRSP limit 2025: 18% of earned income up to $32,490 (rising annually). Withdrawals are taxed at marginal rate in both. Canada has the additional TFSA ($7,000/yr 2025; tax-free growth and withdrawal) — closest US analog is Roth IRA but only $7,000/yr with income limits.

If I move from the US to Canada, what happens to my tax residency?

Canadian tax residency triggers when you establish 'significant residential ties' (a home, spouse, dependants in Canada) or via 183-day rule. US residency ends on departure for resident aliens, but US citizens remain taxed on worldwide income forever. The US-Canada tax treaty provides foreign tax credits, totalization (Social Security ↔ CPP), and IRA/RRSP recognition (transfers possible in limited cases). FBAR filing is still required for any non-US accounts.

Can I transfer my 401(k) to an RRSP?

Yes — a one-time transfer is permitted under the US-Canada treaty. The 401(k) balance must be a 'lump-sum distribution' from a US plan; CRA allows the gross amount (before US 30% withholding) into a Canadian RRSP under section 60(j). You'll need to claim foreign tax credit for the 30% US withholding. Transfers from IRAs are similarly possible but the procedure is more complex. Get specialist US-Canada cross-border advice before any transfer — the wrong sequence triggers double tax with no credit.

Is sales tax different between the US and Canada?

Yes — the US has no federal sales tax; states + cities levy 0% to ~10.25% combined. Canada has federal GST 5% + provincial PST/HST: combined burden ranges from 5% (Alberta, Yukon, NWT, Nunavut) to 15% (NS, NB, NL, PE — HST). Ontario is 13% HST; Quebec is 5% GST + 9.975% QST. On groceries, both countries exempt most basic food. Effective consumption tax is generally higher in Canada, especially in the Atlantic provinces.

US vs Canada Tax — Side-by-Side Comparison for 2026 / 2025

The US and Canada both use progressive federal income tax with state/provincial layers, payroll taxes, and tax-deferred retirement accounts — but the structural details diverge enough to materially change your take-home if you cross the border. This page compares federal + state/provincial income tax, payroll taxes, and retirement schemes using IRS 2026 federal figures (single filer, standard deduction) and CRA 2025 federal + Ontario provincial figures.

Take-home pay on the same nominal salary

Same numeric amount taxed as both a USD salary (IRS federal-only, single filer) and a CAD salary (CRA federal + Ontario provincial + CPP/EI). State income tax is excluded on the US side for clarity — pencil it in separately (see structural-differences table below).

Gross salary	US federal	US FICA	US take-home	CA fed + ON	CPP + EI	CA take-home	Gap
$50,000	$3,820	$3,825	$42,355	$6,962	$3,587	$39,451	+$2,904
$100,000	$13,170	$7,650	$79,180	$19,853	$5,508	$74,639	+$4,541
$150,000	$24,734	$11,475	$113,791	$36,363	$5,508	$108,130	+$5,661
$250,000	$51,304	$15,514	$183,182	$76,247	$5,508	$168,245	+$14,937

Gap shows US take-home minus Canada take-home on the same nominal gross. US federal-only excludes state tax (0–13.3%); add ~$5–13k for state tax in CA/NY/NJ at $100k. Canada side uses Ontario as a representative middle-tax province.

Retirement: 401(k)/IRA vs RRSP/TFSA

Tax-deferred accounts mirror each other but with different limits. US 401(k) accepts $23,500/yr employee + $7,500 catch-up at 50+; total including employer match capped at $70,000. Canadian RRSP accepts 18% of prior-year earned income to a $32,490 cap (2025). Both reduce current taxable income; both are taxed at marginal rate on withdrawal.

Canada's TFSA has no clean US equivalent. $7,000/yr (2025), tax-free growth, tax-free withdrawal — and unused room carries forward indefinitely. Roth IRA is the closest US analog but limited to $7,000/yr with income phase-out (single MAGI $146k–$161k 2026 estimated). Roth 401(k) has no income limit but follows 401(k) deferral rules.

Cross-border treaty. The US-Canada treaty recognises 401(k) and RRSP as 'pensions'; growth is deferred for residents of either country. One-time RRSP-to-401(k) and 401(k)-to-RRSP transfers are possible but procedurally complex (US 30% withholding + foreign tax credit dance). TFSA is NOT treaty-protected — IRS treats it as a foreign trust subject to Form 3520/3520-A reporting and PFIC rules on equity holdings inside.

If you're moving US → Canada

Tax residency: Canadian residency triggers via 'significant residential ties' (home, spouse, dependants) or 183+ days. US residency ends for resident aliens on departure but US citizens remain taxed on worldwide income forever.
US citizen trap: Continue filing US returns from Canada. Use Foreign Earned Income Exclusion (~$130k 2026) + Foreign Tax Credit to avoid double taxation. Renouncing requires Form 8854 + may trigger expatriation tax.
401(k) / IRA: Stays in the US until withdrawal. Canada-resident withdrawal is taxed in both countries, with foreign tax credit. Or transfer to RRSP under section 60(j) (one-shot lump sum, treaty-recognized).
TFSA caution: US citizens shouldn't open TFSA — IRS requires annual Form 3520/3520-A, and PFIC reporting kills any tax efficiency. Stick with RRSP, taxable accounts, and IRA/401(k).
Healthcare: Universal provincial coverage replaces employer health insurance. No more $300+/mo premium deductions — this is a meaningful net-after-cost benefit not visible in pure tax tables.
FBAR / FATCA: Report any Canadian account exceeding US$10k aggregate via FinCEN Form 114 (FBAR). Form 8938 (FATCA) thresholds start at US$50k.

If you're moving Canada → US

Tax residency: US residency triggers via Substantial Presence Test or green card. Canadian residency ends when you sever significant ties (home sold, spouse joins, dependants relocate).
RRSP: Stays preserved; treaty-recognized as US pension (no annual taxation on growth). Withdrawals in the US are taxed at marginal rate; Canadian 25% withholding tax credit available on US return. Or transfer to 401(k) under treaty (limited circumstances).
TFSA: Lose treaty protection on departure; consider closing before leaving. If kept, file US Form 3520/8938 annually and watch for PFIC traps.
Capital gains: Canada deems disposition at departure (the 'departure tax' on world property) — calculate the unrealized gain that crystallizes. US then steps up basis on entry, so plan the timing carefully.
State choice matters: A move to TX/FL/NV/WA leaves you with US federal only — typically beats Canadian federal+ON at $100k+. CA/NY/NJ adds 9–13% on top, narrowing the gap.
Social Security ↔ CPP: Years credited under one system can count toward the other via the Totalization Agreement — useful if you split a career across both.
