RRSP for US Citizens in Canada: Cross-Border Retirement Planning

How an RRSP Works for Canadian Tax Purposes

A Registered Retirement Savings Plan is Canada's flagship tax-deferred retirement vehicle. Contributions are deductible from your Canadian taxable income up to your annual contribution room (18% of prior-year earned income to a 2025 maximum of CAD 32,490, plus carryforward). The plan grows tax-free inside Canada, and distributions are taxed as ordinary income at your marginal rate in the year of withdrawal. Most Canadians use RRSPs as the core of their retirement savings.

As a US citizen Canadian resident, you get the Canadian deduction in full and you generate Canadian tax savings on contribution. The question is whether the IRS taxes the contribution as US-side income (no — it is excluded under treaty interpretation) and whether the IRS taxes the inside-the-plan growth annually (no — Rev. Proc. 2014-55 gives automatic deferral).

• Annual contribution room: 18% of prior-year earned income up to CAD 32,490 (2025).
• Contribution carryforward is unlimited — unused room rolls indefinitely.
• Withdrawals taxed as ordinary income in the year received.

Rev. Proc. 2014-55 and Automatic US Deferral

Before 2014, US citizens with RRSPs had to file Form 8891 every year to elect to defer the inside-the-plan growth from current US tax. Forget the form once and the deferral was lost, with cascading exposure on every year of growth. Revenue Procedure 2014-55 ended that era. Now the deferral is automatic for any eligible RRSP holder — you do not file 8891, you do not file an election, you simply do not include the annual growth on your Form 1040.

The deferral runs until you take a distribution. At that point the entire distribution is US ordinary income, except for any portion attributable to your own after-tax contributions (which is rare because Canadian deductibility means almost all RRSP contributions came from pre-tax dollars). Foreign tax credits for the Canadian withholding tax on the distribution generally zero out the US bill.

Reporting an RRSP to the IRS Even When You Owe No Tax

Automatic deferral does not mean automatic invisibility. Your RRSP is a foreign financial account for FBAR purposes — its peak balance counts toward the $10,000 aggregate trigger. It is also a specified foreign financial asset for FATCA purposes — its year-end and peak balances count toward the Form 8938 thresholds for filers abroad ($200,000 year-end / $300,000 peak for single).

• FBAR (FinCEN Form 114) — RRSP balances count toward the $10,000 aggregate.
• Form 8938 — RRSP balances count toward FATCA thresholds.
• No Form 8621 — the funds inside the RRSP are not treated as PFICs because of Rev. Proc. 2014-55.
• No Form 3520 / 3520-A — the RRSP is not treated as a foreign trust requiring those filings.

Contribution Strategy as a US Citizen in Canada

Contributing to an RRSP gives you a Canadian deduction and US deferral. There is no clean US-side equivalent of the Canadian deduction — your earned income is still subject to US tax — but the foreign tax credit on the Canadian tax you actually pay generally absorbs the US bill. The net result for a typical employee is that the RRSP contribution saves Canadian tax now, the inside-the-plan growth is shielded in both systems, and you pay tax on distribution at retirement age when you can plan around your bracket.

Contribute up to your full Canadian room before contributing to a TFSA (which is a US disaster — see WO-CR02) or non-registered accounts. If you have access to a US 401(k) through a US employer of record, that 401(k) is also a treaty-protected pension under Article XVIII and remains a clean vehicle. RRSP and 401(k) can coexist in the same household.

• Max your RRSP room first — Canadian deduction plus US deferral.
• Avoid TFSAs as a US citizen — fully taxable in the US and triggers Form 3520 / 3520-A.
• US 401(k)s and IRAs are treaty-protected and can stay where they are.

Distribution Mechanics and Cross-Border Withholding

When you take an RRSP distribution as a non-resident of Canada, the CRA withholds 25% under Part XIII (or 15% on periodic pension payments under the treaty's reduced rate). As a US-resident retiree drawing on a Canadian RRSP, you report the distribution on Form 1040, claim a foreign tax credit for the Canadian withholding, and the net US tax is usually zero because the Canadian rate matches or exceeds your US rate on the same income.

Lump-sum withdrawals before age 71 are allowed but expensive — Canadian withholding scales with size, and you lose the deferral. Most cross-border retirees convert RRSPs to RRIFs at age 71 and draw down on the regulated minimum schedule, which qualifies for the lower 15% treaty withholding rate as a periodic pension.

Common Mistakes

The most common mistake is filing the old Form 8891 anyway — the form is obsolete and filing it is harmless but signals confusion. The second most common mistake is including RRSP inside-the-plan growth as US income on Form 1040 because a US accountant unfamiliar with Rev. Proc. 2014-55 thinks it should be reported. The third is forgetting RRSP balances on FBAR or 8938. WO-CR02 (US → Canada Hub) and WO-CS05 (US-Canada Tax Treaty) cover the wider corridor mechanics.
