Frequently Asked Questions
Answers to common questions about cross-border tax filing and our services.
Do I need to file taxes in both Canada and the US?
If you're a US citizen or green card holder living in Canada, yes — you must file tax returns in both countries. Similarly, Canadian residents with US-source income may have filing obligations with the IRS. Our cross-border tax specialists can determine your exact obligations and ensure full compliance.
What is FBAR and do I need to file one?
FBAR (FinCEN Form 114) is required if you're a US person with foreign financial accounts exceeding $10,000 USD in aggregate at any point during the year. This includes Canadian bank accounts, RRSPs, TFSAs, and investment accounts. Failing to file can result in severe penalties.
How can I avoid double taxation between Canada and the US?
The Canada-US Tax Treaty provides mechanisms to avoid double taxation, including foreign tax credits, treaty-based exemptions, and specific provisions for different types of income. Our specialists optimize your returns to take full advantage of these treaty benefits.
