Remote Work for a Canadian Employer

US residents who work remotely for a Canadian employer face a unique set of cross-border issues. Employment income earned while physically present in the US is generally US-source income, even if the employer is Canadian. This affects payroll withholding, social security contributions, and treaty benefit eligibility. Both the employer and employee have compliance obligations in this arrangement.

Key Points

  • Income earned while working in the US is US-source income under Article XV of the Canada-US Tax Treaty.
  • The Canadian employer may need to register for US payroll taxes or use a US employer-of-record.
  • Canada generally cannot tax employment income for services performed entirely outside Canada.
  • The Totalization Agreement determines which country's social security system applies.
  • If the employee occasionally travels to Canada for work, those days create Canadian-source income.
  • State tax obligations depend on the US state of residence and its specific rules for remote workers.

Action Items

  1. 1.Confirm with your employer how US payroll tax withholding will be handled (direct registration or employer-of-record).
  2. 2.Obtain a certificate of coverage under the Totalization Agreement to avoid dual CPP and Social Security contributions.
  3. 3.Track any days worked physically in Canada, as those create Canadian-source income subject to Canadian tax.
  4. 4.File your US return reporting all employment income, including any Canadian-source portion.
  5. 5.Claim foreign tax credits on Form 1116 for any Canadian tax withheld on Canadian-workday income.
  6. 6.Check your state of residence for any specific remote-worker tax rules or credits.

Frequently Asked Questions

Does my Canadian employer need to withhold US taxes?

If you are a US resident working in the US, the employer should withhold US federal and state taxes. Many Canadian employers set up a US payroll entity or use an employer-of-record service to handle this.

Do I still contribute to CPP?

Under the Totalization Agreement, a worker generally contributes to the social security system of the country where they work. If you work in the US, you would typically pay into US Social Security, not CPP, unless a certificate of coverage assigns you to the Canadian system.

What if I work some days in Canada and some in the US?

You must allocate income based on workdays in each country. Canadian-workday income is taxable in Canada (subject to treaty thresholds), and all income is taxable in the US. Foreign tax credits prevent double taxation.

TFSA US Tax Trap

The Tax-Free Savings Account is tax-exempt in Canada but receives no treaty protection in the US. The IRS classifies a TFSA as a foreign grantor trust, requiring Forms 3520 and 3520-A annually. Failure to file can result in penalties starting at $10,000 per form per year.

Critical

FBAR Filing Requirements

The Report of Foreign Bank and Financial Accounts (FBAR) must be filed by any US person with foreign financial accounts exceeding $10,000 in aggregate at any point during the year. The FBAR is filed electronically with FinCEN, not the IRS, and has its own deadline and penalty regime.

Core

Substantial Presence Test

The Substantial Presence Test (SPT) uses a weighted formula across three years to determine if a foreign national is a US tax resident. If you meet the test, you are taxed on worldwide income. Understanding the SPT is essential for snowbirds and anyone splitting time between Canada and the US.
