US vs Canada Taxes Compared: What $100,000 Really Pays in 2026
Real 2026 numbers for a $100K salary on both sides of the border: US federal plus FICA versus Canadian federal, Ontario provincial tax, CPP and EI — plus cross-border rules for commuters and movers.
The Windsor–Detroit Commuter: Why This Comparison Matters
Quick answer: Thousands of people live in Windsor, Ontario and work in Detroit, Michigan every day — earning US dollars while living under Canadian tax residency. The US-Canada tax treaty plus foreign tax credits stop most double tax, but you still file in both countries.
The Windsor–Detroit corridor is the busiest cross-border commuter belt between the two countries, which makes it the perfect real-world example for a US vs Canada tax comparison. A Windsor resident working in Detroit typically pays US federal tax (plus Michigan state tax) on those wages first, then reports the same income on a Canadian return and claims a foreign tax credit for the US tax already paid. The result: double tax is mostly eliminated, but double filing is compulsory.
The trap beginners fall into is residency plus state tax: days spent in each country, residential ties, and Michigan filing obligations all matter. Track your cross-border workdays carefully and get cross-border advice before filing season, not after.
$100K in the US: Federal $13,170 + FICA $7,650
For a single filer earning $100,000 USD in 2026, the US federal-only baseline is simple. Use our Tax Refund Calculator to estimate your own refund or balance due on these figures.
| US Component ($100,000 USD, single, 2026) | Amount |
|---|---|
| Federal income tax | $13,170 |
| FICA (Social Security + Medicare) | $7,650 |
| Total burden | $20,820 |
| Take-home (state $0 baseline) | $79,180 |
The $79,180 take-home uses a $0 state-tax baseline. Real take-home is lower in states with income tax — compare your state on our Paycheck Calculator to see what your salary keeps per paycheck after state withholding. High-tax US states narrow the gap with Ontario significantly.
$100K in Canada (Ontario): The Full Walk-Through
For a single filer earning $100,000 CAD in Ontario in 2026, every layer is computed below. Currency is not converted — dollars stay local: $100K means $100,000 USD on the US side and $100,000 CAD on the Canada side.
Canadian federal tax: $14,393
2026 federal brackets (single, CRA verified): 14% to $58,523, 20.5% to $117,045, 26% to $181,440, 29% to $258,482, 33% above. Note the lowest bracket is 14% (cut from 15% via Bill C-4) — not 15%.
Gross federal: 14% x $58,523 = $8,193.22 plus 20.5% x $41,477 = $8,502.79, giving $16,696.01. The 2026 Basic Personal Amount (BPA) is max $16,452 — a base of $14,829 for everyone plus a $1,623 supplement that phases out from $181,440 to zero at $258,482. At a 14% credit value, the BPA credit is $2,303.28. Federal net: $16,696.01 − $2,303.28 = $14,392.73, about $14,393.
Ontario provincial tax: $6,446
2026 Ontario brackets (representative province, CRA verified): 5.05% to $53,891, 9.15% to $107,785, 11.16% to $150,000, 12.16% to $220,000, 13.16% above. Gross Ontario tax: 5.05% x $53,891 = $2,721.50 plus 9.15% x $46,109 = $4,218.97, giving $6,940.47. The Ontario BPA is approx $11,865 (secondary source — CRA T1 reconfirmation pending), worth $599.18 at 5.05%, leaving basic provincial tax of $6,341.29. Ontario applies a 20% surtax on basic tax above $5,818 (plus an extra 36% above $7,446, for 56% total — pushing the top marginal rate to effectively 20.53%): 20% x ($6,341.29 − $5,818) = $104.66. Ontario total: $6,445.89, about $6,446.
CPP and EI payroll deductions
CPP 2026 (CRA verified): 5.95% rate on earnings between the $3,500 exemption and the $74,600 YMPE gives a max CPP1 of $4,230.45; the second tier (CPP2) charges 4% up to the $85,000 YAMPE for a max of $416.00. At $100K both maximums apply: $4,230.45 + $416.00 = $4,646.45. EI 2026 (CRA and ESDC verified): 1.63% to the $68,900 maximum insurable earnings gives a max employee premium of $1,123.07, which applies in full at $100K.

The bottom line
| Canada Component ($100,000 CAD, single, Ontario, 2026) | Amount |
|---|---|
| Federal income tax (net of BPA) | $14,393 |
| Ontario provincial tax (net of approx BPA + surtax) | $6,446 |
| CPP (CPP1 max + CPP2 max) | $4,646.45 |
| EI (max) | $1,123.07 |
| Total burden | $26,608 |
| Take-home | $73,392 |
Total Canada burden: $14,392.73 + $6,445.89 + $4,646.45 + $1,123.07 = $26,608.13, about $26,608 — take-home about $73,392.*
*The Ontario Health Premium ($750 at $100K income) is excluded from the headline take-home and shown here as a footnote. Including it, take-home would be $72,642.
At $100K, Ontario keeps about $5,788 less than the US federal-only baseline — roughly $73,392 vs $79,180 — and the gap shrinks against high-tax US states. See all our side-by-side guides on the Tax Comparison hub.
TN Visas Under USMCA
A TN visa lets Canadian and Mexican professionals work in the US under the USMCA, but it does not change tax residency by itself. Time spent and ties decide where you are taxed — a long stay usually makes you a US tax resident under the substantial presence test. Commuters from Windsor to Detroit should track days carefully and get advice before filing season.
FEIE vs FTC for Americans Living in Canada
Americans living in Canada must still file US returns every year. The Foreign Earned Income Exclusion lets qualifying expats exclude part of their wages, while the Foreign Tax Credit offsets US tax with Canadian tax already paid. Most Canada-based Americans use the credit because Canadian tax is higher. FBAR and FATCA forms may also apply — confirm your filing obligations with a cross-border professional.
Healthcare: The Honest Tradeoff
Canada's extra ~$5.8K gap at $100K funds universal coverage — doctor and hospital care without monthly premiums or deductibles at the point of care. The US side keeps more of the paycheck but households buy health insurance privately, often thousands per year in premiums plus deductibles. Neither side is free: Canada pays through higher payroll and income taxes (with wait times for some procedures), while Americans pay less tax but carry insurance costs and coverage risk. Compare the full burden — tax plus health costs — before deciding which side leaves you better off.
RRSP vs 401(k)
A 401(k) and an RRSP both cut today's taxable income and grow tax-deferred, but contribution limits, employer matches and withdrawal rules differ by country. Neither is automatically better across the border — the right choice depends on where you will retire, employer matching, and treaty treatment of withdrawals. Get cross-border advice before moving either account across the border.
This USA vs Canada comparison has been verified against official IRS Revenue Procedure — Federal Income Tax Rates and Brackets and the CRA Current year tax rates and income brackets (2026), including the Department of Finance report on the Bill C-4 lowest-bracket reduction, CRA CPP contribution rates and maximums, and CRA EI premium rates and maximums. Ontario figures follow CRA T4032ON parameters; the Ontario BPA is marked approximate pending CRA T1 reconfirmation. Cross-border notes reflect the US-Canada tax treaty framework and do not constitute personalized advice.
Frequently Asked Questions
Generally Canada takes a bigger bite at $100K once federal, provincial, CPP and EI combine, while the US federal-plus-FICA load is lighter before state tax. High-tax US states narrow the gap. The real difference is what you get back — Canada funds universal healthcare through taxes, the US does not.
On a $100K salary in 2026, a single American pays about $13,170 federal plus $7,650 FICA and keeps roughly $79,180 before state tax. In Ontario the same $100K pays about $14,393 federal, $6,446 provincial, $4,646 CPP and $1,123 EI, keeping roughly $73,392. Currency is not converted — dollars stay local.
Usually no — the US-Canada tax treaty plus foreign tax credits stop most double tax, but you still file in both countries. Commuters typically pay tax where they live and claim a credit for tax paid across the border. A cross-border accountant is worth it, because residency rules, state taxes and filing deadlines can trap beginners.
