Do I need to file taxes in both Canada and the US if I work across the border?

It depends on your residency status and the nature of your income. Canadian residents earning US-source income typically report it on their Canadian return and can claim a foreign tax credit for US taxes paid. US citizens living in Canada must also file US returns. Our Mississauga team navigates both tax systems to minimize double taxation.

What is FBAR and do I need to file it?

FBAR (FinCEN 114) is a US filing requirement for US persons with foreign financial accounts exceeding $10,000 USD at any point during the year. Many Canadians with US citizenship or green cards must file. Penalties for non-compliance are severe. We help clients assess their FBAR obligations and file accurately.

What is withholding tax on Canadian income paid to non-residents?

Canada withholds 25% tax (reduced by tax treaties) on certain payments to non-residents, including dividends, rental income, royalties, and management fees. We help non-residents understand their withholding obligations and file NR4, NR6, and Section 216 returns to recover overpaid withholding taxes.

Can BOMCAS Canada help with US expat tax returns for Canadians?

Yes. We assist US citizens and green card holders living in Mississauga and Ontario with their US federal tax returns, FBAR filings, FATCA disclosures, and Foreign Earned Income Exclusion claims — while coordinating with your Canadian tax obligations to avoid double taxation.

How cross-border tax services works for Mississauga clients

Cross-Border Tax Services in Mississauga, Ontario should give Mississauga clients a complete understanding of what the service includes, how records are reviewed, and what happens after the filing or advisory work is complete. BOMCAS Canada treats cross-border tax services as part of a broader tax and accounting picture, not as an isolated form or short checklist. That approach is especially useful when bookkeeping, payroll, GST/HST, corporate tax, personal tax, and CRA correspondence overlap.

The first step is to understand the facts. For cross-border tax services, that usually means reviewing travel history, foreign slips or returns, canadian slips, investment statements, property records and asking targeted questions about timing, income, expenses, ownership, filing history, and CRA account balances. A careful intake helps prevent missed information and gives the client a clear list of what is still needed before the work can be finalized.

The main deliverables often include canadian tax residency review, foreign income reporting support, tax treaty coordination, foreign asset disclosure discussion, departure and arrival tax planning, cra response support. Each deliverable is prepared with attention to accuracy, documentation, and practical follow-up. Where the file involves deadlines, we identify the dates that matter and help the client prioritize the most urgent items first. Where the issue involves a CRA notice or past error, we focus on a response that is complete, factual, and easy to follow.

Many Mississauga clients come to this service because something has become messy, late, unclear, or difficult to explain. Common issues include double reporting concerns, foreign tax credit support, residency tie questions, foreign asset disclosure, u.s. or international income, cra questions about foreign slips. These issues can affect cash flow, refunds, penalties, interest, shareholder balances, HST accounts, payroll accounts, personal tax benefits, or future financing applications. Cleaning up the issue properly can therefore have benefits beyond the immediate tax return.

Our process is also designed for practical communication. Clients receive plain-language explanations of what was reviewed, what was prepared, what assumptions were used, and what should be done next. When additional services are required, we can coordinate this work with bookkeeping services, corporate tax preparation, payroll services, GST/HST filing, or CRA audit representation.

Clients often need cross-border tax services after a deadline, software conversion, staffing change, business growth period, property transaction, payroll issue, or CRA letter. In those situations, the most important step is not simply producing a form; it is rebuilding a reliable file. We look for missing months, unsupported balances, duplicate entries, inconsistent HST or payroll treatment, and transactions that may need more explanation before filing.

Once the records are organized, we prepare the required schedules and explain the results before submission. This review can identify tax balances, possible refunds, installment needs, cash flow pressure, or records that should be improved for next year. The goal is to help the client move from reactive problem-solving to a cleaner, repeatable process.

BOMCAS Canada also helps clients understand what should be retained after the work is complete. Copies of filed returns, confirmations, statements, reconciliations, receipts, contracts, payroll reports, and CRA correspondence should be stored in a way that can be retrieved quickly.
