RRSP for Americans in Canada: Automatic Treaty Deferral & PFIC Rules — 2026

  • RRSP wrapper: Automatic US tax deferral under Rev. Proc. 2014-55 (2014) — no annual Form 8891 required when 1040 is filed on time
  • Funds inside RRSP: Canadian mutual funds and ETFs inside the RRSP are still PFICs — Form 8621 required per fund annually
  • TFSA: Foreign trust under IRS rules — Form 3520 required annually; income NOT tax-deferred for US purposes
  • PFIC default rate: 37% + interest charge on gains calculated from year of purchase — if no election made
  • RDSP: Registered Disability Savings Plan — also a PFIC without specific treaty analysis
  • Safe solution: US-listed funds (Vanguard, Fidelity, iShares) in US brokerage accounts are NOT PFICs

How the Trap Works

RRSPs are tax-deferred in Canada but taxable nightmares in the US without the right election.

🇨🇦
In Canada: RRSP is a tax-deferred retirement account
Canadians contribute pre-tax income to RRSPs, it grows tax-free inside the account, and withdrawals are taxed as ordinary income in retirement. This is exactly how a 401(k) works in the US.
🇺🇸
Since 2014: RRSP = Automatic US Treaty Deferral
Rev. Proc. 2014-55 (effective 2014) eliminated the annual Form 8891 filing requirement. Since then, RRSP and RRIF growth receives automatic US tax deferral under the US-Canada treaty Article XVIII — provided you file your annual US 1040 returns on time. No annual Form 8891 is needed. The RRSP is treated similarly to a 401(k) for US tax purposes during accumulation.
📋
The Real 2026 Risk: What's Inside Your RRSP
The automatic deferral protects the RRSP wrapper — but Canadian-domiciled mutual funds and ETFs held inside the RRSP remain individually classified as PFICs. Each requires a separate Form 8621 filing annually. Canadian bank advisors routinely recommend holding Canadian mutual funds inside RRSPs — for US persons, this creates a PFIC compliance problem even with the treaty deferral on the account itself. Solution: hold only individual Canadian stocks or US-domiciled funds inside the RRSP.
⚠️
TFSA: A different problem entirely
The Tax-Free Savings Account (TFSA) is NOT treated as a retirement account by the IRS — it is classified as a foreign trust. Annual Form 3520 filing is required. Income inside a TFSA is currently taxable for US persons — the tax-free treatment applies only in Canada. Most US expat CPAs advise Americans not to open or contribute to TFSAs.

FAQ

Common questions.

What if I held an RRSP but didn't file US returns for some years?

Rev. Proc. 2014-55 grants automatic treaty deferral — but only when annual US 1040 returns were filed. If you held an RRSP during years you did not file US returns, the automatic deferral did not apply for those years and PFIC rules may have applied to accumulated growth. The IRS Streamlined Filing Compliance Procedures (foreign or domestic) allow eligible non-willful taxpayers to come into compliance. Engage a cross-border CPA specializing in US-Canada issues immediately — the earlier you address this, the lower the complexity and cost.

Can I keep my RRSP after moving to the US?

Yes — and in fact, the US-Canada treaty allows you to continue deferring US tax on RRSP growth after you leave Canada, provided you make the proper treaty election. You cannot contribute to a Canadian RRSP once you are no longer a Canadian tax resident, but existing accounts can be maintained. When you eventually withdraw from the RRSP, the income is taxable in the US (and potentially in the state you live in — states do not all honor the federal treaty treatment).

RRSP automatic deferral since 2014 — but Canadian funds inside are PFICs. The Canada guide covers every cross-border retirement account trap.

RRSP automatic treaty deferral (no Form 8891 since 2014), TFSA Form 3520 trap, Canadian fund PFIC exposure — all covered in the Canada guide.
