RRSP Contributions as a US Citizen in Canada: Deductible Here, Not There, and Still the Right Account

A US citizen living in Canada can contribute to an RRSP like any other Canadian resident, deduct the contribution on the Canadian return, and defer US tax on the plan's growth under the treaty. What they cannot do is deduct the contribution on the US return, which means the contribution creates US basis in the plan that is recovered tax-free on withdrawal. The RRSP is nonetheless the retirement account that works for Americans in Canada: the Canadian deduction is worth more than any US deduction would be, the growth is sheltered on both sides, and the reporting is limited to the FBAR and Form 8938. The TFSA is the account that does not work; the RRSP is the one that does.

Key takeaways

• Canadian side: contributions are deductible up to the annual limit (18% of prior-year earned income to about $32,490 for 2025, plus carried-forward room); growth is tax-free inside the plan; withdrawals are fully taxable.
• US side: contributions are not deductible (with a narrow exception under Article XVIII(8) for contributions to an employer-sponsored plan by a US resident working in Canada); growth is deferred under Article XVIII(7) and Revenue Procedure 2014-55, automatically for eligible individuals; withdrawals are taxable to the extent they exceed US basis.
• US basis: the total of contributions made while the annuitant was a US person (not deducted in the US), plus any amounts previously taxed in the US. Basis is recovered pro rata on withdrawal. Track it from the first contribution.
• Reporting: the RRSP is a foreign financial account on the FBAR and a specified foreign financial asset on Form 8938; no Form 8891 since 2014; no Form 3520.
• Comparison: the RRSP beats a US IRA (no Canadian deduction, and the FEIE blocks IRA eligibility) and the TFSA (taxable in the US, possibly a foreign trust) for an American in Canada.

The Canadian deduction

The annual RRSP deduction limit is 18% of the prior year's earned income (employment, self-employment, rental) up to the dollar maximum, plus unused room from prior years, less pension adjustments from an employer plan. Contributions are deductible in the year made or carried forward. For a US citizen in Canada at a marginal rate of 40% to 53%, a $20,000 contribution saves $8,000 to $10,600 of Canadian tax, which is the binding tax.

The US non-deduction

The Internal Revenue Code does not recognize an RRSP as a qualified plan, so contributions are not deductible on the 1040. Article XVIII(8) of the treaty allows a deduction for contributions to a Canadian employer-sponsored plan (a group RRSP or RPP) by an individual who performs services as an employee in Canada, was contributing to the plan before starting the Canadian employment, and is resident in the US; it does not help a US citizen resident in Canada. In practice, Americans in Canada contribute to RRSPs without a US deduction.

The non-deduction has a modest cost because the foreign tax credit usually eliminates US tax on the Canadian salary regardless; the deduction would have reduced US tax that was already zero. It has a benefit: the contributions create US basis.

The deferral

Under Article XVIII(7), a US resident (including a US citizen resident in Canada) may elect to defer US tax on income accrued in an RRSP until distribution. Revenue Procedure 2014-55 treats eligible individuals as having made the election automatically, eliminating the former Form 8891. The growth inside the plan (interest, dividends, gains) is not reported on the 1040 while it stays in the plan. Canadian mutual funds inside the RRSP are not subject to the PFIC rules because of the deferral.

Withdrawals and basis

When the annuitant withdraws (or the RRIF pays), Canada taxes the full amount (as income for a resident, or by Part XIII withholding for a non-resident). The US taxes the withdrawal to the extent it exceeds the annuitant's basis, recovered pro rata (each withdrawal is part basis, part income, in the ratio of basis to total plan value). For a US citizen who contributed $200,000 to an RRSP now worth $500,000, 40% of each withdrawal is tax-free in the US and 60% is taxable, with a foreign tax credit for the Canadian tax on the whole withdrawal. The credit usually covers the US tax.

Basis must be tracked from the beginning. A US citizen who has contributed for twenty years without records reconstructs basis from contribution receipts and notices of assessment.

Reporting

The RRSP appears on the FBAR (FinCEN Form 114) at its maximum value for the year and on Form 8938 (as a foreign financial asset) if the thresholds are met. Nothing else: no Form 3520 (the RRSP is not a foreign trust for this purpose after the 2014 guidance), no Form 8621 for holdings inside it, no Form 8891.

Versus the alternatives

IRA. Requires taxable compensation not excluded by the FEIE; no Canadian deduction; the US deduction is worth little to someone with no US tax after the credit; the Roth is tainted by Canadian contributions. The RRSP wins.

TFSA. Taxable in the US annually; conservative position is a foreign trust with Forms 3520 and 3520-A. Most Americans in Canada should not hold one. The RRSP wins.

Employer RPP. A defined benefit or defined contribution pension is treaty-deferred like the RRSP; employer contributions are not US income when made; employee contributions are not US-deductible and create basis. Works the same way.

Taxable account. No deduction, no deferral; US-listed ETFs to avoid PFICs. The RRSP wins for retirement savings.

Worked example

A US citizen in Vancouver earning $160,000 CAD contributes $25,000 CAD to an RRSP each year for ten years; the plan grows to $400,000 CAD by the time she retires and moves to Arizona.

• Each year in Canada. $25,000 deducted on the T1, saving about $11,000 CAD at her marginal rate. No US deduction; the foreign tax credit already covers her US tax. Basis accumulates: $25,000 a year, $250,000 CAD total. RRSP on the FBAR and Form 8938.
• In Arizona, RRIF withdrawals of $30,000 a year. Canada withholds 15% ($4,500). US: basis ratio $250,000 / $400,000 = 62.5%; $18,750 tax-free, $11,250 taxable; US tax about $2,500 at her rate less the $4,500 credit (limited to the US tax on the foreign income): zero US tax, about $2,000 of excess credit. Arizona taxes the $11,250 taxable portion at 2.5%.

Practitioner note

The RRSP is the one Canadian account we tell every American in Canada to use, and the one thing we tell them to keep is the contribution record, because twenty years later the basis is the difference between a tax-free withdrawal and a taxable one on the US side. Contribute to the RRSP, close the TFSA, skip the IRA, and keep the receipts.
