The IRS does not see your TFSA as tax-free

TFSA & PFIC Traps for US Citizens in Canada

If you are a US citizen or green card holder living in Canada, your "tax-free" TFSA and your everyday Canadian mutual funds can quietly become a US tax and reporting nightmare. The IRS taxes TFSA income and treats Canadian funds as PFICs. We clean it up and keep it compliant.

Quick answer

Does a US citizen in Canada have to pay US tax on a TFSA?

Generally, yes. A TFSA's Canadian tax exemption does not automatically exclude its income from a US citizen's or green-card holder's US return. Interest, dividends and gains may therefore be taxable in the United States. FBAR and Form 8938 reporting depend on their separate thresholds. Canadian mutual funds and ETFs may be passive foreign investment companies requiring Form 8621 analysis. Whether a particular TFSA arrangement is also a foreign trust requiring Forms 3520 or 3520-A is fact-dependent; the IRS has not issued TFSA-specific guidance that makes those trust forms universal.

Four separate reviews

Do not collapse TFSA reporting into one yes-or-no answer

  • Report the account's income under US tax rules.
  • Test the account for FBAR and Form 8938 reporting.
  • Review each Canadian fund for Form 8621 and PFIC treatment.
  • Analyze the account terms and administration before concluding that foreign-trust forms apply.

The Three Account Traps

TFSA - not tax-free to the IRS

Income and gains inside a TFSA are taxable on your US return. Depending on the structure it can also be a foreign trust, triggering Form 3520 and 3520-A.

Canadian mutual funds = PFICs

Most Canadian funds and ETFs are PFICs under the definition in IRC §1297. Each needs a separate Form 8621 yearly, with punitive default tax unless a QEF or mark-to-market election is made.

RRSP - the one with treaty cover

RRSPs get treaty deferral under Article XVIII(7) of the Canada-US Tax Treaty, so growth is not taxed until withdrawal. They still need FBAR/8938 reporting but avoid the PFIC and trust traps.

What We Do

  • Prepare Form 8621 for each PFIC, with QEF or mark-to-market election analysis to minimize tax
  • File Form 3520 and 3520-A where a TFSA or RESP is treated as a foreign trust
  • Apply RRSP treaty deferral correctly and report RRSP, TFSA, and RESP on FBAR and Form 8938
  • Recommend a cleaner go-forward structure to avoid PFIC and trust reporting entirely
  • Coordinate catch-up under the IRS Streamlined Procedures if past years of TFSA or PFIC reporting were missed

TFSA & PFIC FAQs

Is a TFSA taxable in the US?
Yes. The IRS does not treat the TFSA as tax-free. Its income and gains are taxable on your US return, and it may also be a foreign trust requiring Form 3520 and 3520-A.
Why are Canadian mutual funds a PFIC problem?
They are Passive Foreign Investment Companies. Each fund needs its own Form 8621 each year, and the default regime applies top ordinary rates plus an interest charge unless a QEF or mark-to-market election is made.
Is my RRSP taxed by the IRS?
Generally no, while it grows. The treaty defers US tax on RRSP growth until withdrawal. It still needs FBAR and usually Form 8938 reporting, but avoids the PFIC and trust traps.
What should I hold instead?
Many US persons in Canada move toward US-domiciled ETFs or individual securities to avoid PFIC and trust reporting. We review your accounts and map a compliant, lower-friction structure.

Not sure what else might be exposed?

TFSA and PFIC issues rarely show up alone. Run the 60-second diagnostic to check FBAR, Form 5472, FinCEN BOI, and other cross-border triggers at the same time.
