Getting Back Into U.S. Tax Compliance
Many U.S. citizens living in Canada — including “Accidental Americans” — are surprised to learn that they may still have ongoing U.S. tax filing obligations, even if they have lived in Canada for years. Discovering this can feel overwhelming, but there are established IRS programs designed specifically to help individuals return to compliance.
Our firm regularly assists Canadian-resident U.S. citizens who were previously unaware of their U.S. filing requirements, including those seeking relief under the IRS Streamlined Offshore Procedures. We take a careful, compliance-focused approach to assess eligibility, prepare the required filings, and guide clients through the process with clarity and discretion.
If you believe you may have unfiled U.S. tax returns or information reporting obligations, we invite you to get in touch to discuss your situation and next steps.
