Cross-Border Individuals & Families


Having filing obligations in both Canada and the U.S. means two sets of rules, two sets of forms, and two deadlines — and when they aren't coordinated, the same income can end up taxed on both sides. We handle dual Canada–U.S. returns, the tax treatment of cross-border investment accounts, and the disclosure of foreign assets and accounts, so the two filings line up under one plan rather than being prepared in isolation.

Who this is for

  • Families holding Canadian PR alongside a U.S. green card or U.S. citizenship
  • Canadian residents with U.S.-source income or U.S. assets
  • Dual-status individuals holding TFSA, RRSP or RESP accounts who need the U.S. treatment clarified
  • Snowbirds and dual residents who winter between Canada and the U.S.
  • Students and work-permit holders who need their residency status determined
  • Non-U.S. persons who need an ITIN to complete a U.S. filing

What we cover

Dual filing & credit coordination

  • Canadian T1 and U.S. 1040 filed in parallel for the same year
  • Foreign tax credit coordination across borders to prevent the same income being taxed twice
  • Canada–U.S. tax treaty positions: residency tie-breaker and pension articles
  • Employment, self-employment, investment and rental income sourced and reported across both countries

U.S. treatment of cross-border accounts

  • TFSA and RESP characterization and reporting impact under U.S. tax (possible foreign-trust filings)
  • RRSP/RRIF treaty-based deferral and the associated disclosures
  • PFIC (passive foreign investment company) exposure on non-U.S. mutual funds and ETFs
  • Dividends, interest and capital gains in cross-border brokerage accounts handled in both countries

Foreign asset & account reporting

  • FBAR (FinCEN Form 114): required when a U.S. person's foreign financial accounts aggregate over US$10,000
  • Form 8938 (FATCA): reporting of specified foreign financial assets
  • T1135: required when a Canadian resident's specified foreign property exceeds CAD$100,000 in cost
  • Disclosure mapping for foreign real estate, foreign company interests and similar holdings

Residency determination & numbers

  • Form 8843 and U.S. residency (substantial presence test) for students and visiting scholars
  • Residency start/end and first- and last-year filings for work-permit holders and secondees
  • ITIN (W-7) applications and renewals, handled through the certifying-acceptance-agent process
  • Residency-change analysis for relocations, returns and long-term commuting

How we work

  1. 01

    Map the situation

    We first establish each family member's status, income sources and account holdings on both sides to confirm which obligations actually apply to you.

  2. 02

    Gather records

    Through a secure portal we collect both countries' workpapers, account statements and prior returns, flagging items such as PFICs and foreign accounts that need extra disclosure.

  3. 03

    Coordinate the filings

    We align the T1 and 1040 for the same year under the treaty and credit rules, and prepare the accompanying FBAR, 8938 and T1135 filings so both sides are consistent.

  4. 04

    Review & archive

    A CPA reviews the full package before filing; we retain the workpapers and advise on withholding and account arrangements for the year ahead.

Frequently asked

I'm a U.S. citizen living in Canada and I already pay Canadian tax. Do I still file with the IRS?

Yes. The U.S. taxes on the basis of citizenship, so you file a 1040 every year regardless of where you live. The foreign tax credit or the foreign earned income exclusion usually prevents actual double taxation, so in most cases you don't truly pay twice — but the filing itself can't be skipped. How much you can offset depends on the income type and the tax paid in each country.

Is a TFSA really a problem for U.S. persons?

A TFSA is tax-free in Canada, but the U.S. doesn't recognize that status, so the income inside it is generally still reportable year by year on the U.S. side, and some holdings can trigger foreign-trust or PFIC reporting, which adds cost. Whether it's worth keeping depends on your overall picture, so it's worth a conversation before opening one or adding to it.

What's the difference between FBAR and T1135 — do I file both?

They belong to different countries. The FBAR is the U.S. report of a taxpayer's foreign financial accounts, due when they aggregate over US$10,000 at any point in the year; T1135 is the Canadian report of a resident's specified foreign property, due when its cost exceeds CAD$100,000. If you're a taxpayer in both countries and meet each threshold, both can be required.

Do students need to file?

Usually yes. Even with no income, F/J visa holders generally file Form 8843 to claim the days excluded from the substantial presence test; with scholarship, internship or investment income, a full return may be required. Whether you're treated as a tax resident depends on your days present and visa type, and that determination drives which forms apply.

I don't have a U.S. Social Security Number. How do I file in the U.S.?

You can apply for an ITIN (Individual Taxpayer Identification Number). It's for people who aren't eligible for an SSN but have a U.S. filing or withholding obligation, and it's usually applied for together with your first return using Form W-7, with proof of identity. As a certifying acceptance agent, we can verify your original passport so you don't have to mail your documents away.
