Frequently Asked Questions

Question 1- Do I need to file tax returns in both the US and Canada when I relocate?

Answer 1- You may have filing obligations in both countries, depending on your tax residency, citizenship, income sources and the timing of your move. A relocation does not automatically end all Canadian tax obligations or establish US tax residency for every purpose. Your circumstances should be reviewed to determine the appropriate filing requirements.

Question 2- What happens to my Canadian tax residency when I move to the US?

Answer 2- Canadian tax residency depends on the facts and circumstances, including residential ties and other relevant considerations. Your departure date and the treatment of income around the move may affect your Canadian tax reporting. US tax residency is determined separately under applicable US rules, with treaty provisions potentially relevant in certain cases.

Question 3- Can I claim foreign tax credits on my US and Canadian tax returns?

Answer 3- Foreign tax credits may be available to mitigate double taxation, subject to the applicable domestic tax rules and treaty provisions. The amount and timing of the credits can differ between countries, so the income and taxes should be reviewed in the context of both returns.

Question 4- Can you help employers with cross-border employee assignments?

Answer 4- Yes. Taxoria can assist with cross-border employment tax compliance, Canadian T4 reporting, taxable benefit calculations, gross-ups and hypothetical tax calculations, as applicable to the engagement.

Question 5- When should I seek cross-border tax advice?

Answer 5- Ideally, before relocating or accepting a cross-border assignment. Early planning can help identify potential residency issues, filing requirements and tax implications before they become more difficult to address. Assistance is also available after a move has occurred.
