Living in the United States and working in Canada is legal for US citizens and green card holders, but it takes three things lined up at once: a Canadian work permit, a tax plan that handles filings in both countries, and a workable routine for crossing the border. Most people who do this live in border regions like Detroit, Buffalo, or Bellingham, though the same rules apply to anyone who flies into Canada for work on a regular schedule. The work authorization is the entry ticket. The taxes are where most commuters get into trouble.
Getting a Canadian Work Permit
Most foreign nationals need a work permit to hold a job in Canada.1Government of Canada. Work Permit Permits split into two groups: those that require a Labour Market Impact Assessment (LMIA), and those that don’t. An LMIA is a document from Employment and Social Development Canada confirming no Canadian citizen or permanent resident is available for the role, and the Canadian employer has to apply for it before you can apply for the permit.2Government of Canada. Find Out if You Need a Labour Market Impact Assessment Because that adds time and cost, most US citizens look at LMIA-exempt options first.
CUSMA Professional Permits
The Canada-United States-Mexico Agreement (CUSMA, formerly NAFTA) creates several LMIA-exempt categories for US citizens. The most-used one is the professional category, covering a defined list of occupations including engineers, accountants, scientists, and management consultants. You need US citizenship, a prearranged job offer from a Canadian employer in a listed occupation, and the educational credentials the occupation requires. CUSMA professional status can often be granted directly at a Canadian port of entry, which is much faster than most permit routes.
Intra-Company Transfers
If your current employer has offices in both countries, an intra-company transfer (ICT) permit can move you to the Canadian office without an LMIA. It applies to executives, managers, and workers with specialized knowledge of the company’s products or processes. Updated Canadian guidance from 2024 says applicants generally need at least two years of experience with the foreign company to qualify, up from the previous one-year benchmark.3KPMG.

Social Insurance Number
Once your permit is in hand, you need a Canadian Social Insurance Number (SIN) before you can legally start work. A SIN is required to work in Canada and to receive government program benefits.4Government of Canada. Social Insurance Number – Do You Qualify Temporary workers get a SIN starting with “9” that expires with the work permit. You’ll also need it to open an interest-bearing Canadian bank account, which most employers require for payroll.
If You’ll Work Remotely From the US
Not every reader here plans to physically cross into Canada. If a Canadian company hires you and you do all your work from a home office in the United States, you generally don’t need a Canadian work permit, because you aren’t working in Canada. Canada also typically can’t tax employment income for work performed entirely on US soil, since its taxing authority over non-residents reaches only Canadian-source income, meaning income earned while physically present in Canada. Occasional trips to the Canadian office complicate this: those days can trigger Canadian tax obligations and possibly permit requirements. The cleaner you keep the geographic split, the simpler your compliance.
Crossing the Border for Work
US citizens don’t need a visa to enter Canada, and visitors can stay up to six months.5Government of Canada. What You Need to Enter Canada6Immigration, Refugees and Citizenship Canada. How Long Can I Stay in Canada as a Visitor Entering to work is different. Tell the officer you’re crossing for employment and present your work permit or the Port of Entry letter issued with your authorization, along with a valid US passport or passport card.
Commute daily or several times a week and border time compounds fast. A NEXUS card is worth the money. NEXUS gives access to dedicated lanes at land crossings and expedited kiosks at airports, cutting wait times significantly.7U.S. Customs and Border Protection. Benefits of NEXUS The card costs $120 for five years and includes Global Entry when reentering the US.
A Warning for Green Card Holders
US citizens can cross without any effect on their immigration status. Green card holders have to be more careful. Prolonged absences can be treated as abandonment of permanent residency. The general benchmark is more than a year outside the US, but abandonment findings can happen with shorter trips if the government believes you no longer treat the US as your permanent home.8USCIS. International Travel as a Permanent Resident Daily or weekly commuting while keeping your US home and coming back each night or weekend shouldn’t create problems. The risk is with extended, continuous stays in Canada.
Filing Taxes in Both Countries
This is where the arrangement gets genuinely complicated. You’ll owe tax in two countries on the same wages, and the system for preventing double taxation works, but only if you use the right relief mechanism.
US Tax on Worldwide Income
US citizens and green card holders owe federal income tax on their worldwide income regardless of where they earn it.9Internal Revenue Service. US Citizens and Residents Abroad Filing Requirements Your Canadian salary goes on your US return.
Canadian Tax on Your Employment Income
Canada taxes non-residents on Canadian-source income, including wages for work physically done in Canada. You’ll pay Canadian federal income tax on that pay plus a surtax that stands in for provincial tax for non-residents. Your Canadian employer withholds both, similar to how a US employer withholds federal and state taxes.
The Foreign Tax Credit
The US-Canada tax treaty prevents double taxation, and for a US resident the practical mechanism that delivers that relief is the Foreign Tax Credit.10Internal Revenue Service. Foreign Tax Credit You file Form 1116, report the Canadian income taxes you paid, and the IRS credits them against your US tax on the same income. The credit can’t exceed the US tax attributable to your foreign-source income, calculated as total US tax multiplied by foreign taxable income divided by total taxable income.11Internal Revenue Service. Foreign Tax Credit – How to Figure the Credit Canadian tax rates are generally comparable to or higher than US federal rates, so the credit often wipes out most or all of the double-tax problem.
Why the FEIE Almost Certainly Doesn’t Apply
The Foreign Earned Income Exclusion (FEIE) lets qualifying taxpayers exclude up to $132,900 of foreign earnings for the 2026 tax year.12Internal Revenue Service. Figuring the Foreign Earned Income Exclusion It doesn’t apply to you if you live in the United States. The FEIE requires either bona fide residence in a foreign country for a full tax year, or physical presence in a foreign country for at least 330 days in a 12-month period.13Internal Revenue Service. Foreign Earned Income Exclusion – Bona Fide Residence Test A cross-border commuter whose home is in the US fails both tests. The FEIE is built for Americans living abroad. Claiming it when you don’t qualify is an audit risk.
Watch Your State
Your state of residence can add another layer. Not every state gives a credit for taxes paid to a foreign country the way the federal system does. Some states only credit taxes paid to other US states, which can leave you paying full Canadian tax and full state income tax on the same earnings with no offset. Check your state’s rules before you assume the federal Foreign Tax Credit logic carries over.
Social Security and CPP
The US-Canada totalization agreement coordinates Social Security contributions so you don’t pay into both systems on the same wages.14Social Security Administration. Totalization Agreement with Canada The default rule: you pay into the country where you physically work. Employed by a Canadian company doing the work in Canada means contributing to the Canada Pension Plan (CPP) instead of US Social Security.
There’s an exception for workers temporarily sent to Canada by a US employer. If the assignment is expected to run five years or less, you can stay on US Social Security. The employer requests a certificate of coverage to establish the exemption. The agreement also lets you combine contribution periods from both countries to qualify for benefits, which matters if your career spans both.
Health Insurance
Health coverage is where cross-border commuters often end up exposed. Most US employer-sponsored plans give limited or no coverage for care received outside the United States. Some reimburse emergency treatment abroad; routine care in Canada usually isn’t covered. Canadian provincial health insurance generally requires you to be a provincial resident, which you aren’t. The result is a gap: potentially no coverage while you’re at work in Canada.
Options to close it include supplemental international health insurance, travel medical insurance sized to your work trips, or a careful call with your US insurer to see what your specific plan covers across the border. If your Canadian employer offers group health benefits, ask whether work-permit holders can enroll. Don’t assume either system covers you by default.
Driving Across for Work
If you commute by car, you can drive your US-registered vehicle in Canada as a temporary import for as long as your work permit is valid.15Transport Canada. Temporarily Importing Vehicles For stays longer than three months, Transport Canada recommends declaring the vehicle as a temporary import, which also lets you register it provincially. Permanent import or re-registration isn’t necessary for normal commuting.
Auto insurance deserves more attention than most commuters give it. Your US policy may or may not cover regular driving in Canada, and a daily work commute is different from a vacation drive. Call your insurer before you start commuting. Confirm your coverage extends to Canada, ask whether trip frequency matters, and find out whether you need a rider or endorsement. If they won’t cover regular cross-border driving, find an insurer who will or add a separate Canadian policy.
Getting Paid and Moving Money
Canadian employers usually pay by direct deposit into a Canadian account, so you’ll likely need one. Canadian banks allow non-residents to open accounts with a passport, immigration documents, and a work permit. Your SIN is required for any interest-earning account. Some US banks with Canadian operations, or Canadian banks with US correspondents, can start the paperwork before you arrive.
Earning Canadian dollars while spending US dollars at home makes currency exchange a recurring cost. Rates move, and bank conversion fees eat into your pay. Many commuters keep accounts on both sides of the border and use specialized transfer services that beat retail bank rates. Keep records of the exchange rates you actually receive on each transfer, since you’ll need them to convert your Canadian income to US dollars on your tax return.
