KEY INSIGHT
A Canadian RRSP is NOT automatically tax-deferred in the United States. Without a treaty election on Form 8833, the IRS taxes RRSP growth annually as ordinary income. However, the Canada-US Double Tax Treaty (Article XVIII, paragraph 7) allows US residents and US citizens to elect to defer US tax on RRSP/RRIF accumulations until withdrawal — matching how Canada treats the RRSP. This election must be made on Form 8833 in the first year you become a US resident (or the first year you have RRSP income, if you forgot to elect earlier). The RRSP must also be reported annually on FBAR (FinCEN 114).

Key Facts

The Treaty Election: Form 8833 and Article XVIII(7)
The Canada-US Tax Treaty (formally: the Convention Between Canada and the United States of America with Respect to Taxes on Income and on Capital, as amended) contains a specific provision for RRSPs and RRIFs in Article XVIII, paragraph 7. This paragraph allows a US resident or US citizen who is a beneficiary of a Canadian RRSP or RRIF to elect to defer US income tax on income accrued in the plan until distribution. Without this election: the IRS treats the RRSP as a foreign grantor trust (IRS Notice 2003-75), which means the annual growth (interest, dividends, capital gains inside the RRSP) is currently taxable to the US beneficial owner each year. With the election: US tax is deferred until distributions are made from the RRSP or RRIF — matching Canadian treatment. How to elect: file Form 8833 (Treaty-Based Return Position Disclosure) with your Form 1040. Check the applicable DTA article (Article XVIII(7) for Canada). The election is made once per plan and carries forward — you do not need to refile Form 8833 every year for the same RRSP after the initial election. First year timing: make the election in the first year you become a US tax resident with an existing RRSP, or in the first year you open an RRSP as a US resident. Late elections: the IRS will generally allow late Form 8833 elections through amended returns, but it is better to elect on time.
RRSP FBAR and Form 8938 Reporting Obligations
An RRSP is a foreign financial account for FBAR purposes (FinCEN 114). If the RRSP account value exceeds $10,000 at any point during the year: file FBAR. Multiple RRSPs: report each one separately (FBAR requires account-by-account disclosure). The RRSP account number (Canadian institution's reference) is the identifier. RRSP spousal: report the spousal RRSP you contributed to (you have a financial interest even if the account is in your spouse's name). Form 8938 (FATCA): RRSP is also reported on Form 8938 if total foreign financial assets exceed the applicable threshold ($50,000 for US residents; $200,000 for Americans abroad). The treaty deferral election does not eliminate the reporting obligation — you must still report the account; you just don't report the annual income if you've made the Article XVIII(7) election. Form 3520/3520-A (Foreign Trust): the IRS has historically argued that an RRSP is a foreign grantor trust. However, IRS Notice 2003-75 provides that a US beneficiary of an RRSP is not required to file Forms 3520/3520-A for RRSPs (and RRIFs, PRPPs) — the reporting obligation is limited to FBAR and Form 8938. This Notice remains in effect; do not file Form 3520 for your RRSP unless specifically advised otherwise.
RRSP Contributions and Withdrawals: US Tax Treatment
Contributions: RRSP contributions are deductible in Canada but are NOT deductible in the US. A US resident who contributes to an RRSP gets no US tax deduction. The contribution is made with after-US-tax dollars. This creates an important basis issue: the contributed amounts are 'basis' from a US perspective. Growth: deferred under the treaty election. Withdrawals: when you withdraw from the RRSP (or convert to RRIF with mandatory annual withdrawals), the full gross withdrawal is subject to US ordinary income tax rates. BUT — the basis created by the non-deductible contributions reduces the taxable amount: taxable withdrawal (US) = gross RRSP withdrawal − basis in the RRSP (accumulated non-deductible contributions). Tracking basis: critical to document every RRSP contribution made while a US resident, as these create US basis. Canadian withholding on RRSP withdrawals: 25% withholding for non-resident withdrawals (reduced to 15% under the DTA for periodic payments; 25% for lump-sum). This Canadian withholding becomes a Foreign Tax Credit on your US return (Form 1116). RRIF withdrawals: same treaty deferral applies. RRIF minimum withdrawals begin at age 71 — plan ahead for the US tax impact of mandatory RRIF distributions.
TFSA: The Problem Account for US Persons
The Tax-Free Savings Account (TFSA) is one of Canada's most popular savings vehicles — but it is a serious problem for US tax purposes. Why: the TFSA has no equivalent under US tax law. The IRS likely treats the TFSA as a foreign grantor trust (Form 3520/3520-A) or as a plain taxable account — there is no treaty provision equivalent to Article XVIII(7) for TFSAs. US consequences: (1) TFSA growth is currently taxable in the US each year — dividends, interest, and capital gains inside the TFSA are not deferred for US purposes. (2) Form 3520 (Annual Return to Report Transactions with Foreign Trusts) may be required each year if the TFSA is treated as a foreign grantor trust — the $10,000 penalty for failure to file Form 3520 applies. (3) FBAR and Form 8938 reporting required. (4) PFIC issues: if the TFSA holds Canadian mutual funds or ETFs, PFIC rules apply (see below). Practical advice for dual US-Canadian residents: consider not using a TFSA if you have US filing obligations. If you have a TFSA from before establishing US residency: consult a cross-border CPA on your specific position — some argue the TFSA is not a trust but rather a standard foreign account.
PFIC Rules and Canadian Mutual Funds / ETFs in RRSPs
PFIC (Passive Foreign Investment Company) rules apply to foreign corporations that are primarily passive in nature. Most Canadian mutual funds and ETFs are PFICs for US tax purposes. PFIC consequences without election: (1) 'Interest charge' regime: gains and 'excess distributions' (distributions exceeding 125% of average distributions over prior 3 years) are taxed at the highest ordinary income tax rate plus an interest charge going back to the year the PFIC shares were acquired. (2) No capital gains rates — all PFIC gains are ordinary income. PFIC elections to mitigate: (1) QEF (Qualified Electing Fund) election: annual inclusion of pro-rata share of PFIC ordinary earnings and net capital gain. Requires a PFIC annual information statement (Form 8621). Few Canadian fund companies provide this statement. (2) Mark-to-Market (MTM) election: elect to be taxed on unrealised gains annually; losses deductible against prior MTM gains. Used when QEF is unavailable. For RRSPs with treaty deferral election: when the PFIC holdings are inside an RRSP and the Article XVIII(7) election is in place — the prevailing view is that PFIC rules do not apply to RRSP holdings while deferral is in effect, because the income is not currently recognised. However, this is not explicitly confirmed by IRS guidance. The PFIC issue is most acute for TFSAs (no deferral) and non-registered Canadian accounts. Safest approach for US residents: hold US-listed ETFs (not Canadian-listed) in RRSPs to avoid PFIC complexity.
Introduction

The RRSP is Canada's most valuable retirement savings vehicle — but for Americans living in Canada, Canadians moving to the US, and dual citizens, the RRSP creates significant US tax complexity. The Canada-US DTA provides a deferral mechanism, but it requires an active election. Failure to elect means paying US tax on RRSP growth every year — a common and costly mistake for cross-border individuals who don't know about the Form 8833 requirement.

Cross-Border Planning Checklist: Moving from Canada to the US with an RRSP

If you are moving from Canada to the United States with an existing RRSP, follow this sequence:

  1. Before departure from Canada: Confirm your RRSP account details (account numbers, institution, current value, all contributions made with after-tax Canadian dollars — these form your future US basis). Consider making a final RRSP contribution for the year of departure (deductible in Canada for the full year if you are a Canadian resident at December 31, or departure date if you depart before year-end).
  2. Year of US arrival: File Form 8833 with your first US tax return to elect treaty deferral under Article XVIII(7). Keep a copy permanently. Report the RRSP on FBAR (FinCEN 114) — file by October 15. If total foreign assets exceed $200,000 (living abroad) or $50,000 (US resident), report on Form 8938.
  3. During US residency: File FBAR annually. Do not contribute to the RRSP (no US tax benefit). Track any contributions made — they create US basis. Review RRSP holdings — consider switching to US-listed ETFs to avoid PFIC exposure.
  4. At RRSP withdrawal: Calculate US taxable amount = gross withdrawal − accumulated US basis. Claim Canadian withholding tax as Foreign Tax Credit on Form 1116. Report on Form 1040 as ordinary income.

FAQ

Frequently Asked Questions

What happens if I never filed Form 8833 for my RRSP and I'm now a US resident?

Without a timely Form 8833 election, the IRS treats RRSP income (growth) as currently taxable in the US each year. If you have been a US resident for several years without making the election, you may have unreported RRSP income on past US returns. Options: (1) File amended returns (Form 1040-X) for open years (generally the last 3 years) to include the treaty election on Form 8833 for each year. This 'backdates' the election retroactively. Because the RRSP income was not previously reported, the amended returns would typically show zero additional tax (the treaty election means no tax is due) — but you are making the disclosure. (2) If income was already reported on previous returns: amended returns to claim the treaty deferral may generate a refund of taxes paid on RRSP growth. (3) If using Streamlined Compliance Procedures: include Form 8833 with the amended returns. Practical experience: the IRS generally accepts late Form 8833 elections through amended returns without penalty, particularly when the taxpayer can show the failure was an oversight and no US tax was evaded (since treaty deferral eliminates the tax). Document the election carefully and retain permanently.

Can a US citizen living in Canada contribute to an RRSP and get a US deduction?

No — RRSP contributions are not deductible for US federal income tax purposes. The US tax code provides deductions only for contributions to US-qualified retirement plans (401(k), IRA, SEP-IRA, etc.). The Canada-US DTA Article XVIII(7) provides deferral of RRSP income but does NOT extend deductibility of RRSP contributions. Result: a US citizen in Canada contributes $30,000 to an RRSP: Canadian deduction — yes, saves ~$12,000–$15,000 in Canadian tax. US deduction — no. The $30,000 is made with after-US-tax dollars and becomes US basis in the RRSP. On withdrawal: Canadian RRSP tax applies at marginal rate; US taxes the amount above the US basis. If the Canadian rate is higher than the US rate: the Foreign Tax Credit should offset US tax. The RRSP is still worth using for US citizens in Canada primarily for the Canadian tax benefit — the US basis tracking is an administrative burden but not a disaster.

Should a US citizen in Canada use a TFSA?

Generally no — unless you have specific advice from a cross-border CPA on your situation. The TFSA's tax benefits in Canada (tax-free growth and withdrawal) are not recognised by the US. For a US citizen using a TFSA: (1) TFSA growth is fully taxable in the US each year as ordinary income — the 'tax-free' Canadian benefit is fully offset by US taxation. (2) If the TFSA is a foreign trust: Form 3520 required annually — $10,000 penalty for failure. (3) PFIC issues if Canadian funds are held. (4) FBAR and Form 8938 reporting required. Alternatives: US citizens in Canada should instead maximise their US Individual Retirement Account (IRA or Roth IRA) — these are US-recognised retirement plans. Roth IRA: $7,500/year limit; no deduction, but tax-free growth and withdrawals. Canada's treatment of Roth IRA: not tax-deferred in Canada (Canada does not recognise Roth IRAs as pension plans); growth is taxable in Canada annually. There is no perfect answer — a cross-border CPA can help optimise between Canadian and US registered account usage.

How is RRSP income taxed when I'm a US resident receiving RRIF withdrawals?

RRIF mandatory annual withdrawals are taxed as follows: Canada: RRIF withdrawals are ordinary income in Canada; Canadian withholding applies (25% for lump sum, 15% for periodic under DTA). US (with treaty election in place): the RRIF withdrawal is taxable as ordinary income in the US. Calculation: US-taxable amount = gross RRIF withdrawal − pro-rata share of accumulated US basis. US basis is the total of non-deductible contributions made to the RRSP while a US resident (each year tracked). If you never contributed while a US resident: zero basis — full withdrawal is US-taxable. Foreign Tax Credit: Canadian withholding tax on the RRIF withdrawal is creditable dollar-for-dollar against your US income tax liability on the same income (Form 1116). In most cases where Canadian rates exceed US rates: the FTC eliminates US income tax on RRIF withdrawals, and no double taxation occurs. State income tax: some US states do not recognise the Canada-US DTA and may tax RRIF withdrawals without allowing an FTC. Check your state — this is particularly relevant in California.
