Canadian on an L-1 Transfer: The Tax Side of Being Moved by Your Company

The L-1 is the corporate move: your employer transfers you from the Canadian office to the U.S. one. It feels like the easiest way to arrive — the company handles the visa, often the movers, sometimes the house-hunting trip. Which creates a dangerous assumption: the company is handling the taxes too.

Mostly, it isn't. Your employer handles its compliance — payroll withholding, its own filings. Your personal cross-border position — the Canadian exit, the dual-status year, the accounts you left behind, the equity you're carrying — is yours. Here's what an L-1 transferee actually needs to watch.

The relocation package is (mostly) taxable

That generous package — movers, temporary housing, a lump-sum allowance, house-hunting trips — is, for U.S. federal purposes, generally taxable compensation. Some employers "gross up" to cover the tax; many don't, or only partially. If nobody told you the $20,000 relocation benefit would appear in your income, the first pay stub or the W-2 will. Know before you spend it.

Two payrolls, one year

Transfers often straddle systems: Canadian payroll until the transfer date, U.S. payroll after — and sometimes a messy overlap where duties are performed in one country while pay runs through the other. That split matters, because where you performed the work drives which country taxes the income and what the treaty does with it. Bonuses earned over a period spanning the move, unused vacation paid out after departure, trailing Canadian pay — each needs to land in the right country's column. The totalization agreement keeps you from paying into both CPP and U.S. Social Security for the same work, but only if the payrolls are set up correctly.

Stock options and RSUs cross the border with you

This is the L-1's signature tax problem. Equity granted while you worked in Canada but vesting or exercised after you moved is sourced across both countries, generally based on where you worked during the earning period. Both Canada and the U.S. will want their slice; the treaty referees. Handled well, you get credits and no double tax. Handled by ignoring it, you get taxed twice or misreport in one country. If you're carrying options or RSUs across the border, this single issue justifies professional help.

The standard arrival stack still applies

Everything every Canadian arriver faces applies to you too:

• Substantial Presence Test residency — a normal L-1 year makes you a U.S. tax resident on worldwide income (how the day-count works);
• a dual-status first-year U.S. return;
• a final Canadian return with a departure date, and departure tax on non-registered investments;
• FBAR once your Canadian accounts top the $10,000 combined threshold (full guide), with the RRSP reportable-but-deferred and the TFSA a genuine problem to address before residency starts.

Don't let the ease of the move lull you

The L-1's comfort is the trap: because the company moved you, the personal filings feel like someone else's job. They aren't — and HR's relocation guide was written for employees from everywhere, not for the specific U.S.–Canada mesh of departure tax, treaty sourcing, and account reporting.
