RRSP Contributions as a US Citizen in Canada

Yes, a US citizen living in Canada can contribute to an RRSP, and in most cases should. The RRSP is the core tax-deferred retirement vehicle in Canada, and the Canada-US tax treaty allows the US to recognize the tax deferral if you make a one-time election. But the cross-border mechanics create questions that domestic Canadians never face: whether the contribution is deductible on the US return, how contribution room works when you have earnings in both countries, what happens to employer matching, and whether the RRSP or a US-side account is the better vehicle. The short answer is that the RRSP is deductible on the Canadian return, not directly deductible on the US return, and the treaty election defers US tax on the growth inside the account. For most Americans in Canada with employment income, contributing up to the Canadian limit is the right move.

Is the RRSP contribution deductible on the US return?

No, not directly. The RRSP deduction is a Canadian concept under ITA 60(i). On your US return, the contribution is made with after-tax dollars (from the US perspective). There is no US equivalent of the RRSP deduction, and IRC 219 (which governs IRA deductions) does not extend to foreign retirement plans.

However, the practical impact is smaller than it appears:

• The contribution reduces your Canadian taxable income, which reduces your Canadian tax. Lower Canadian tax means a smaller foreign tax credit on your US return (because there is less Canadian tax to credit). But since Canadian rates generally exceed US rates, the credit typically covers the US tax on Canadian-source income either way. The net effect is that the RRSP contribution saves you Canadian tax at your marginal rate, and the US side is approximately neutral.
• If you have excess foreign tax credits (which most Americans in Canada do), the RRSP contribution has no incremental US cost at all: the credit pool shrinks, but it was larger than needed to begin with.

The treaty election does not make the contribution deductible. It makes the growth inside the RRSP tax-deferred on the US side. Without the election, the IRS would tax the interest, dividends, and capital gains earned inside the RRSP every year as current income, even though you made no withdrawal.

How does the treaty election work?

Under Article XVIII(7) of the Canada-US tax treaty, a US citizen or resident who is a beneficiary of a Canadian registered pension plan (including an RRSP) can elect to defer US taxation on accrued income in the plan until it is distributed. The IRS implemented this through Rev. Proc. 2014-55.

• The election is made by attaching a statement to your US return for the first year you want the deferral to apply. The statement identifies the plan, states that you are electing deferral under the treaty, and includes the information required by Rev. Proc. 2014-55. Once made, the election stays in effect for all future years (you do not need to renew it).
• If you missed making the election in an earlier year, you can make a late election under the same revenue procedure, though you may need to file amended returns for the years where you should have reported the income but did not.

How much can I contribute?

RRSP contribution room is calculated by the CRA based on your prior-year earned income. The formula:

• 18% of prior-year earned income, up to the annual RRSP dollar limit ($32,490 for 2025, $33,810 for 2026)
• Minus your pension adjustment (PA) from any registered pension plan (RPP) or deferred profit-sharing plan (DPSP) your employer contributes to
• Plus any unused room carried forward from prior years

“Earned income” for RRSP purposes includes employment income, self-employment income, and net rental income (among others). It does not include investment income (interest, dividends, capital gains) or pension income.

If you arrived in Canada mid-year, your earned income for that partial year determines the room available for the following year. If you had no Canadian earned income before arriving, you start with zero room and build it in your first full year of work.

Your RRSP room is shown on your Notice of Assessment from the CRA each year, or on My Account at canada.ca.

Does employer matching use my room?

Yes. Employer contributions to a group RRSP use your contribution room, just like your own contributions. If your employer matches your contributions dollar-for-dollar up to 5% of salary, and your salary is $100,000, the employer match is $5,000. That $5,000 counts against your room.

• If your employer contributes to a registered pension plan (RPP) rather than a group RRSP, the pension adjustment (PA) on your T4 slip reduces your RRSP room by an equivalent amount. The CRA calculates this automatically.
• The total RRSP contribution (your contributions plus employer contributions to a group RRSP) cannot exceed your available room without triggering the 1% per month over-contribution penalty under ITA 204.1. There is a $2,000 lifetime buffer before the penalty kicks in.

Can I contribute to both an RRSP and a US IRA?

You can, but the IRA deduction may be limited. If you are covered by an employer retirement plan in Canada (a group RRSP or RPP counts as a “retirement plan” for IRA purposes under IRC 219(g)), the IRA deduction phases out at relatively low income levels ($87,000 to $107,000 AGI for single filers in 2025). If your Canadian employment income exceeds those thresholds (which it often does for the demographics that hire cross-border accountants), the traditional IRA deduction is zero.

• You can still contribute to a Roth IRA (income limits permitting), but Canada does not recognize the Roth IRA as tax-exempt unless you file the treaty election for the Roth.
• The practical recommendation for most Americans in Canada: maximize the RRSP first (it is deductible on the Canadian side, where rates are higher), then consider a Roth IRA if you are below the income limits and have already made the Canadian treaty election.

What investments should I hold in the RRSP?

The RRSP is one of the few accounts where a US citizen in Canada can safely hold Canadian-listed ETFs and mutual funds without PFIC problems. The treaty election defers US tax on the income inside the RRSP, which means the PFIC regime (which taxes annual mark-to-market gains or excess distributions) does not apply while the assets remain in the RRSP.

• This makes the RRSP the natural home for Canadian-listed index funds. Outside the RRSP, you should hold US-listed ETFs to avoid PFIC reporting. Inside the RRSP, Canadian-listed equivalents (which often have lower management fees for Canadian-dollar investors) are fine.
• One constraint: the RRSP holds qualified investments as defined by the CRA. Most publicly traded securities, GICs, and mutual funds qualify. Private company shares and some alternative investments may not.

How is the RRSP reported on the US return?

The RRSP itself is not reported as income on the US return (assuming the treaty election is in place). But you have several US reporting obligations:

• FBAR (FinCEN 114). The RRSP is a foreign financial account. If the aggregate value of all your foreign accounts (RRSP, bank accounts, TFSAs if you still have one, brokerage accounts) exceeds $10,000 at any point during the year, you file an FBAR.
• Form 8938. If the value of your foreign financial assets exceeds the reporting thresholds ($200,000 at year-end or $300,000 at any point for Americans abroad filing single, higher for MFJ), you report the RRSP on Form 8938.
• Treaty election statement. Attached to the return in the first year (and in any year where the election was not previously made).

You do not file Form 8621 (PFIC) for investments held inside the RRSP if the treaty election is in place.

What should I do next?

If you are a US citizen working in Canada, contributing to the RRSP is almost always the right move. The key steps are making the treaty election on your US return, checking your contribution room on the CRA’s My Account, and structuring the investments inside the RRSP to take advantage of the PFIC shelter.
