How the US-Canada Tax Treaty Treats Your RRSP: Article XVIII and the $100K Cross-Border Case

Quick Answer

Article XVIII of the Canada-US tax treaty does two things for your RRSP. First, paragraph 7 defers US tax on undistributed RRSP income — meaning growth inside the account is not taxed annually by the IRS, mirroring how Canada treats it. This deferral has been automatic since the IRS eliminated Form 8891 in 2014 (Revenue Procedure 2014-55). Second, when you withdraw, the treaty caps Canadian non-resident withholding at 15% on pension distributions (down from the default 25% under Part XIII of the Income Tax Act). The IRS then taxes the full withdrawal as ordinary income but allows a dollar-for-dollar foreign tax credit for the Canadian withholding on Form 1116. On a $100,000 RRSP withdrawal by a US resident: Canada withholds $15,000 (treaty rate), the US taxes the full $100,000 as ordinary income, and the $15,000 credit offsets US tax — so you pay the higher of the two countries' rates, not both stacked. The TFSA gets none of this protection.

Key Takeaways

1Article XVIII(7) of the Canada-US tax treaty defers US tax on income accruing inside an RRSP. Since Revenue Procedure 2014-55 (December 2014), this deferral is automatic — no annual election or form filing is required beyond normal US tax returns.
2When a US resident withdraws from a Canadian RRSP, CRA imposes a 25% non-resident withholding tax under Part XIII of the Income Tax Act. The treaty reduces this to 15% for pension distributions. Converting the RRSP to a RRIF and taking periodic payments qualifies for the 15% treaty rate.
3The IRS taxes the full gross RRSP distribution as ordinary income. The Canadian withholding generates a foreign tax credit on Form 1116 that offsets US federal tax dollar-for-dollar, up to the US tax on that income. On a $100,000 withdrawal, the $15,000 Canadian withholding typically eliminates most or all of the double-taxation risk.
4TFSAs get zero treaty protection. The IRS treats a TFSA as a foreign grantor trust, requiring Forms 3520 and 3520-A annually. All TFSA income is taxable on the US return each year. Penalties for missed filings start at US$10,000 per form per year.
5FBAR (FinCEN 114) and Form 8938 (FATCA) reporting are required for any US person with a financial interest in a Canadian RRSP exceeding the applicable thresholds — regardless of whether a withdrawal has been made.

If you're a Canadian who moved to the US, a US citizen who worked in Canada, or a dual citizen with an RRSP sitting at a Canadian institution — the tax treatment of that account depends almost entirely on Article XVIII of the Canada-US tax treaty. Get it right and the RRSP works nearly as well cross-border as it does domestically. Get it wrong — or ignore it — and you face annual US tax on undistributed growth, 25% Canadian withholding instead of 15%, and potential penalties for missed FBAR and FATCA filings.

Below: how Article XVIII protects RRSP income from double taxation, a step-by-step $100,000 withdrawal example showing exactly how both countries tax the same dollar, why the TFSA gets none of this protection, and the reporting obligations that trip up most cross-border filers.

Cross-border tax disclaimer

Cross-border Canada-US tax planning involves the interaction of two countries' tax codes, a bilateral treaty, and multiple filing obligations. The rates and rules cited below are verified against CRA, IRS, and treaty sources as of June 2026. Your specific outcome depends on residency status, total worldwide income, state-level taxes, and the nature of the distribution. This article explains the mechanics — a cross-border tax specialist (CPA with both US and Canadian credentials) should model your personal numbers before you make withdrawal decisions.

What Article XVIII Actually Does for Your RRSP

Article XVIII of the Canada-US tax treaty covers pensions, annuities, and registered retirement plans. For RRSP holders with US tax exposure, two provisions matter:

1. The deferral: no US tax on undistributed RRSP income (Article XVIII, paragraph 7)

Without the treaty, the IRS would tax you annually on every dollar of interest, dividends, and capital gains earned inside your RRSP — even if you never withdrew a cent. That's because the US taxes its citizens and residents on worldwide income, and a Canadian RRSP is just a foreign account in the IRS's eyes.

Article XVIII(7) fixes this. It allows a US person to elect to defer US tax on undistributed RRSP income, matching how Canada treats the account — no tax until withdrawal. Since Revenue Procedure 2014-55 (December 2014), this election is automatic. The IRS eliminated Form 8891, which previously had to be filed every year to claim the deferral. Now, any eligible individual — defined as someone who is or was a beneficiary of a Canadian retirement plan and has filed required US tax returns — is deemed to have made the election.

The practical result: your RRSP grows tax-deferred in both countries simultaneously, just like a traditional IRA would in the US.

Form 8891 is gone — but reporting isn't

The deferral election is automatic, but FBAR (FinCEN 114) and Form 8938 (FATCA) reporting obligations still apply if your RRSP exceeds the applicable thresholds. The deferral covers taxation; it does not eliminate disclosure.

2. The withholding cap: 15% instead of 25% on distributions (Article XVIII, paragraph 2)

When a non-resident of Canada withdraws from an RRSP, CRA imposes a 25% withholding tax under Part XIII of the Income Tax Act. That's the default domestic rate for any non-resident receiving Canadian-source retirement income.

The treaty overrides this. Article XVIII(2) caps the source-country tax on pension distributions at 15%. To claim the reduced rate, the recipient (or the Canadian financial institution acting on their behalf) files form NR301 — a declaration of treaty benefits. Without it, the institution withholds the full 25%.

The standard cross-border planning move: convert the RRSP to a RRIF and take periodic withdrawals, which clearly qualify as pension distributions under the treaty and lock in the 15% rate.

The $100,000 Cross-Border RRSP Withdrawal: Step-by-Step Tax Math

A former GTA resident, now living in the US and filing as a US tax resident, withdraws $100,000 CAD from their Canadian RRSP (converted to a RRIF, periodic payments). They're in the 24% US federal bracket. Here's how both countries tax the same $100,000:

Step	What happens	Amount
1. Gross withdrawal	Full RRIF distribution amount	$100,000 CAD
2. Canadian withholding (treaty rate)	15% under Article XVIII(2), via NR301	−$15,000
3. Cash received	Net of Canadian withholding	$85,000 CAD
4. US tax on full $100,000	Reported as ordinary income on Form 1040 (converted to USD at the applicable exchange rate). At 24% federal bracket:	~$24,000 USD-equivalent
5. Foreign tax credit (Form 1116)	$15,000 CAD of Canadian withholding, converted to USD, credited against US tax	−~$15,000 USD-equivalent
6. Net US tax owing	US tax minus foreign tax credit	~$9,000 USD-equivalent
Total combined tax (both countries)	$15,000 CAD withholding + ~$9,000 USD net US tax	~$24,000 USD-equivalent

Simplified illustration. Actual amounts depend on the CAD/USD exchange rate at the time of withdrawal, total worldwide income, US state taxes (if applicable), and whether the FTC limitation applies. The key mechanism: you pay the higher of the two countries' rates on the income, not both stacked.

Without the treaty, the same withdrawal would face 25% Canadian withholding ($25,000) plus 24% US tax ($24,000) with only a partial credit — a potential combined bill approaching $49,000. The treaty cuts this nearly in half.

What if you didn't file NR301?

If the Canadian institution withholds 25% ($25,000) instead of 15% because NR301 wasn't filed, the extra $10,000 of Canadian withholding generates a larger foreign tax credit on Form 1116 — but it may exceed the FTC limitation (the US tax attributable to that income). The excess becomes a carryforward credit, not a refund. You've overpaid Canada and underpaid the US, with cash locked in a credit you may not use for years. Filing NR301 upfront is the cleaner path.

Canadian Resident's RRSP vs. US Resident's RRSP: The Key Differences

Feature	Canadian resident	US resident (with treaty protection)
Tax on growth inside the RRSP	Deferred until withdrawal	Deferred until withdrawal (Article XVIII(7))
Contributions	Deductible from Canadian income; generates RRSP room	No new room if not earning Canadian income. US does not allow a deduction for RRSP contributions.
Withholding on withdrawal	10%/20%/30% graduated (interim withholding, not final tax)	25% Part XIII (treaty-reduced to 15%)
Final tax on withdrawal	Added to taxable income; taxed at marginal rate (up to 53.53% in Ontario)	Canadian withholding is final (no Canadian return needed). US taxes the gross as ordinary income; FTC offsets the Canadian portion.
RRIF conversion deadline	By Dec 31 of the year you turn 71	Same deadline applies regardless of residency
Reporting	RRSP appears on T1 return at withdrawal	FBAR (FinCEN 114) + Form 8938 + Form 1040 reporting of distributions

The critical difference: for a Canadian resident, the RRSP withdrawal withholding is an interim payment against your final tax bill (you settle up on your T1 return). For a US resident, the Canadian withholding is the final Canadian tax — you don't file a Canadian return for the withdrawal. Your real tax settlement happens on the US side, where the Canadian withholding becomes a credit.

The TFSA Trap: Why Article XVIII Doesn't Help Here

The most expensive mistake cross-border filers make with Canadian accounts isn't getting the RRSP wrong — it's assuming the TFSA works the same way.

The Canada-US tax treaty is completely silent on TFSAs. The TFSA was created in 2009, after the treaty was last substantively amended. There is no Article XVIII protection, no deferral election, and no reduced withholding rate.

The IRS treats a TFSA as a foreign grantor trust. That classification triggers three consequences:

Annual US taxation: all income earned inside the TFSA — interest, dividends, capital gains — is taxable on the US return every year, even if nothing is withdrawn.
No foreign tax credit: Canada charges $0 tax on TFSA income, so there's nothing to credit against the US tax. You pay full US rates with no offset.
Form 3520 and 3520-A: annual information returns for foreign trusts. Penalties for non-filing start at US$10,000 per form per year — and there are two forms, so the exposure is $20,000/year for simply not filing.

Feature	RRSP (treaty-protected)	TFSA (no treaty protection)
US tax on growth	Deferred until withdrawal	Taxed annually
Foreign tax credit available?	Yes (on Canadian withholding at withdrawal)	No (Canada charges $0 — nothing to credit)
US filing burden	FBAR + Form 8938 (balance reporting)	FBAR + Form 8938 + Forms 3520 & 3520-A
Non-filing penalty risk	$10,000+ per form	$10,000+ per form × more forms = higher exposure

For a GTA professional who moves to the US or holds dual citizenship: the RRSP is the account to keep. The TFSA, counterintuitively, becomes a tax and compliance liability on the US side. Many cross-border tax specialists recommend collapsing the TFSA before or shortly after becoming a US tax resident.

FBAR and FATCA: The Reporting That Exists Regardless of Article XVIII

Article XVIII handles taxation. It does not eliminate the US obligation to disclose foreign financial accounts. Two separate regimes apply:

Reporting requirement	Threshold	Form	Penalty for non-filing
FBAR	Aggregate foreign accounts > US$10,000 at any point in the year	FinCEN 114	Up to US$10,000 per violation (non-willful); up to US$100,000 or 50% of account balance (willful)
FATCA (Form 8938)	US$50,000 at year-end or US$75,000 at any point (single); US$100,000 at year-end (joint)	Form 8938	US$10,000 per failure; up to US$50,000 for continued non-filing

A $100,000 CAD RRSP triggers both thresholds. FBAR is filed separately from the tax return (electronically via FinCEN's BSA E-Filing system) and is due April 15 with an automatic extension to October 15. Form 8938 is attached to your 1040.

The penalty structure is aggressive enough that the filing cost (often minimal — most cross-border accountants include these with the return) is trivially cheap insurance.

Three Planning Moves That Follow From Article XVIII

Convert RRSP to RRIF before drawing down. Periodic RRIF payments lock in the 15% treaty-reduced withholding rate. If you withdraw a lump sum directly from the RRSP without conversion, the institution may apply the full 25% Part XIII rate. The RRIF conversion costs nothing and is standard cross-border practice.
File NR301 with the Canadian institution. This is the form that triggers the treaty-reduced 15% withholding. Without it, the institution defaults to 25%. Some institutions have the form on file permanently; others require it to be refreshed. Confirm yours is current before the first withdrawal.
Collapse the TFSA before or shortly after becoming a US tax resident. Unlike the RRSP, the TFSA has no treaty protection. Every year you hold it as a US person, you owe US tax on the growth plus compliance costs for Forms 3520 and 3520-A. A cross-border tax specialist can time the collapse to minimize the combined Canadian/US impact.

The broader principle: Article XVIII makes the RRSP one of the most treaty-friendly retirement accounts in any bilateral tax relationship. The TFSA, by contrast, is the most problematic. If you're a Canadian moving to the US or a dual citizen choosing where to contribute, the treaty math strongly favours the RRSP.

Frequently Asked Questions

Q:Does the Canada-US tax treaty defer US tax on RRSP growth?

A:Yes. Article XVIII(7) of the Canada-US tax treaty allows US persons to defer US tax on income accruing inside an RRSP, analogous to how a traditional IRA is treated under US domestic law. Since the IRS issued Revenue Procedure 2014-55 in December 2014, the deferral election is automatic for eligible individuals — defined as anyone who is or was a beneficiary of a Canadian retirement plan and has filed required US tax returns. Prior to 2014, the election required filing Form 8891 annually. That form was eliminated; no replacement form is needed for the deferral itself.

Q:What is the Canadian withholding tax rate on RRSP withdrawals for US residents?

A:The default non-resident withholding rate under Part XIII of the Income Tax Act is 25%. The Canada-US tax treaty (Article XVIII) reduces this to 15% for pension distributions, which includes RRSP and RRIF payments. To claim the reduced treaty rate, the recipient (or the Canadian financial institution) must file form NR301 (Declaration of Benefits Under a Tax Treaty for a Non-Resident Taxpayer). Without NR301, the institution will withhold at the full 25% domestic rate.

Q:Can I use the foreign tax credit to avoid double taxation on my RRSP withdrawal?

A:Yes. Canadian withholding tax paid on an RRSP distribution can be claimed as a foreign tax credit on IRS Form 1116. The credit offsets US federal income tax dollar-for-dollar, up to the US tax attributable to the Canadian-source income. On a $100,000 RRSP withdrawal with $15,000 of Canadian withholding (treaty rate), if your US federal tax on that income is $22,000, the credit reduces your US tax to $7,000 — so your total combined tax is $22,000 (the higher country rate), not $37,000 (both stacked).

Q:Does the Canada-US tax treaty protect TFSAs from US taxation?

A:No. The Canada-US tax treaty is completely silent on TFSAs. The TFSA was created in 2009, after the treaty was last substantively amended. The IRS treats a TFSA as a foreign grantor trust, meaning all income earned inside the TFSA — interest, dividends, capital gains — is taxable on the US return annually. Worse, there is no foreign tax credit available because Canada charges $0 tax on TFSA income (nothing was paid to credit). US persons must file Forms 3520 and 3520-A annually. Penalties for non-filing start at US$10,000 per form per year. For a US person with Canadian accounts, the RRSP has full treaty protection; the TFSA has none.

Q:Do I need to file FBAR and FATCA for my Canadian RRSP?

A:Yes. A US person with a financial interest in a Canadian RRSP must file FinCEN Form 114 (FBAR) if the aggregate value of all foreign financial accounts exceeds US$10,000 at any point during the calendar year. Separately, Form 8938 (Statement of Specified Foreign Financial Assets) is required if total foreign financial assets exceed US$50,000 at year-end (US$75,000 at any point) for single filers, or US$100,000 at year-end for joint filers. A $100,000 CAD RRSP easily triggers both thresholds. FBAR is due April 15 with an automatic extension to October 15. Form 8938 is filed with your tax return. These reporting obligations exist whether or not you make a withdrawal.

Q:Should I convert my RRSP to a RRIF before withdrawing as a US resident?

A:Converting to a RRIF and taking periodic payments can reduce Canadian withholding from 25% to 15% under the treaty. For a US resident drawing down a large RRSP, this is the standard cross-border planning move. RRIF periodic payments clearly qualify as pension distributions under Article XVIII, locking in the 15% treaty-reduced withholding rate. The trade-off: RRIF minimum withdrawals are mandatory once converted (starting at 5.28% at age 71 per CRA prescribed factors), and you lose the flexibility of a lump-sum RRSP withdrawal. A cross-border tax specialist can model which approach produces the lower combined tax bill for your specific income level and timing.

Answer: The default non-resident withholding rate under Part XIII of the Income Tax Act is 25%. The Canada-US tax treaty (Article XVIII) reduces this to 15% for pension distributions, which includes RRSP and RRIF payments. To claim the reduced treaty rate, the recipient (or the Canadian financial institution) must file form NR301 (Declaration of Benefits Under a Tax Treaty for a Non-Resident Taxpayer).

Answer: Yes. Canadian withholding tax paid on an RRSP distribution can be claimed as a foreign tax credit on IRS Form 1116. The credit offsets US federal income tax dollar-for-dollar, up to the US tax attributable to the Canadian-source income. On a $100,000 RRSP withdrawal with $15,000 of Canadian withholding (treaty rate), if your US federal tax on that income is $22,000, the credit reduces your US tax to $7,000 — so your total combined tax is $22,000 (the higher country rate), not $37,000 (both stacked).

Question: Does the Canada-US tax treaty protect TFSAs from US taxation?

Answer: No. The Canada-US tax treaty is completely silent on TFSAs. The TFSA was created in 2009, after the treaty was last substantively amended. The IRS treats a TFSA as a foreign grantor trust, meaning all income earned inside the TFSA — interest, dividends, capital gains — is taxable on the US return annually.

Penalties for non-filing start at US$10,000 per form per year. For a US person with Canadian accounts, the RRSP has full treaty protection; the TFSA has none.

Question: Do I need to file FBAR and FATCA for my Canadian RRSP?

Answer: Yes. A US person with a financial interest in a Canadian RRSP must file FinCEN Form 114 (FBAR) if the aggregate value of all foreign financial accounts exceeds US$10,000 at any point during the calendar year. Separately, Form 8938 (Statement of Specified Foreign Financial Assets) is required if total foreign financial assets exceed US$50,000 at year-end (US$75,000 at any point) for single filers, or US$100,000 at year-end for joint filers. A $100,000 CAD RRSP easily triggers both thresholds. FBAR is due April 15 with an automatic extension to October 15. Form 8938 is filed with your tax return. These reporting obligations exist whether or not you make a withdrawal.

Question: Should I convert my RRSP to a RRIF before withdrawing as a US resident?

Answer: Converting to a RRIF and taking periodic payments can reduce Canadian withholding from 25% to 15% under the treaty. For a US resident drawing down a large RRSP, this is the standard cross-border planning move. RRIF periodic payments clearly qualify as pension distributions under Article XVIII, locking in the 15% treaty-reduced withholding rate. The trade-off: RRIF minimum withdrawals are mandatory once converted (starting at 5.28% at age 71 per CRA prescribed factors), and you lose the flexibility of a lump-sum RRSP withdrawal. A cross-border tax specialist can model which approach produces the lower combined tax bill for your specific income level and timing.
