Moving from the US to Canada with retirement savings? This guide covers the tax-efficient transfer of 401(k)s, IRAs, Roth accounts, and coordination with Social Security. Unlike UK pensions, US retirement accounts cannot be directly transferred to Canadian registered accounts—but with proper planning, you can optimize outcomes. For comprehensive wealth management strategies, explore our private wealth management services in Toronto.
🎯 Executive Summary
No Direct Transfer
You cannot directly roll a 401(k) or IRA into a Canadian RRSP—there is no "QROPS equivalent" for US plans
Treaty Protection
Canada-US Tax Treaty (Article XVIII) lets you defer tax on US retirement accounts while Canadian resident
TFSA Warning
Never hold US investments in a TFSA—the US doesn't recognize it and will tax all growth annually
Timing Matters
Strategic withdrawal timing can minimize total tax across both countries
Types of US Retirement Accounts
- Traditional 401(k) – employer-sponsored
- Traditional IRA – individual
- 403(b) – non-profits, education
- 457(b) – government employers
- SEP IRA – self-employed
- SIMPLE IRA – small business
- Roth 401(k) – employer-sponsored
- Roth IRA – individual
- Roth 403(b) – non-profits
⚠️ Roth accounts have special considerations—Canada taxes growth if treaty election not filed
Canada-US Tax Treaty: Article XVIII
✅ Key Protection: Tax Deferral Continues
The Canada-US Tax Treaty allows your 401(k) and IRA to continue growing tax-deferred while you're a Canadian resident—you don't have to withdraw or transfer upon moving.
401(k)/IRA Deferral
Growth continues tax-free until withdrawal; Canada honors the deferral
US Withholding
15% treaty rate on periodic pension payments (vs 30% standard); claimed as foreign tax credit. Note: lump-sum distributions from 401(k) or IRA accounts are generally subject to 30% mandatory withholding under US domestic law. Some custodians may apply the treaty rate, but this should not be assumed.
Canadian Tax
Distributions taxed as ordinary income; foreign tax credit for US withholding
Roth Election
One-time election (treaty Art. XVIII(7)) to defer Canadian tax on Roth growth
📋 Official Government Resources
Critical: TFSA and US Persons
The TFSA is invisible to the IRS. The US does not recognize the TFSA as a tax-advantaged account. If you remain a US citizen or green card holder:
- All TFSA growth is taxable annually to the US
- Foreign mutual funds in TFSA trigger PFIC rules (punitive taxation)
- FBAR and Form 8938 reporting required for TFSA
Your Options: What To Do With US Retirement Accounts
Roth Accounts: Special Considerations
Without the Treaty Election, Canada Taxes Roth Growth
Canada does not automatically recognize Roth accounts as tax-exempt. You must file a one-time election under Article XVIII(7) of the Canada-US Tax Treaty to defer Canadian tax on Roth earnings.
File the Election
Attach a letter to your first Canadian tax return as a resident electing treaty benefits for Roth accounts
Basis vs Growth
Your Roth contributions (basis) are not taxed; only growth could be if election not filed
Qualified Withdrawals
After age 59½ and 5-year rule, withdrawals are US tax-free and Canadian tax-free (with election)
US Social Security Benefits
US Treatment
Up to 85% of benefits taxable depending on income; non-resident withholding may apply
Canadian Treatment
Under the tax treaty, only 85% is included in Canadian income—15% is exempt
Totalization Agreement
US and Canadian work credits can be combined to qualify for benefits in either country
WEP/GPO Repealed
Note: The Social Security Fairness Act, signed January 5, 2025, repealed both the Windfall Elimination Provision (WEP) and Government Pension Offset (GPO). Canadian pension income no longer reduces your US Social Security benefits. This is a significant positive change for cross-border workers.
📋 Official Resources
US Reporting Obligations for Canadian Residents
If you remain a US citizen or green card holder, you have ongoing US tax obligations even while living in Canada:
Form 1040
Annual US tax return required; foreign earned income exclusion may help
FBAR (FinCEN 114)
Report foreign accounts exceeding $10,000 aggregate; includes RRSP, TFSA, bank accounts
Form 8938 (FATCA)
Report specified foreign financial assets above threshold ($200k-$600k for foreign residents)
PFIC Reporting
Canadian mutual funds are PFICs; requires Form 8621 and potentially punitive tax treatment
Tax-Efficient Withdrawal Strategies
1. Low-Income Transition Year
If you have a year with little income (career change, sabbatical), consider larger 401(k)/IRA withdrawals to "fill up" low tax brackets in both countries.
2. Pre-Age 59½ Planning
Use "substantially equal periodic payments" (72(t)) to avoid 10% early withdrawal penalty if you need funds before 59½.
3. Roth Conversion Ladder
Convert Traditional IRA to Roth in low-income years; after 5-year seasoning, withdraw tax-free in both countries.
4. Coordinate with RRSP
Time US withdrawals against RRSP/RRIF income to balance total income across your retirement years.

Quick Comparison: US Accounts for Canadian Residents
| Account Type | Can Transfer to RRSP? | Canadian Tax Treatment | Recommendation |
|---|---|---|---|
| Traditional 401(k) | ❌ No direct transfer | Distributions taxed as income; FTC for US withholding | Keep in US or roll to IRA; withdraw strategically |
| Traditional IRA | ❌ No direct transfer | Same as 401(k) | Consider Roth conversions in low-income years. Important: Roth IRA conversions made after you become a Canadian tax resident may be treated as ‘Canadian Contributions’ under CRA rules, which could partially invalidate your treaty election for the converted amount. Many cross-border advisors recommend completing any Roth conversions before establishing Canadian residency. |
| Roth 401(k) | ❌ No direct transfer | Tax-free with treaty election; taxable without | File treaty election immediately; roll to Roth IRA |
| Roth IRA | ❌ No direct transfer | Tax-free withdrawals with treaty election | File treaty election; ideal vehicle for US persons in Canada |
| US Social Security | N/A | 85% taxable in Canada (15% exempt under treaty) | Coordinate claiming age with Canadian CPP/OAS |

Frequently Asked Questions
Can I transfer my 401(k) directly to a Canadian RRSP?
No, there is no mechanism to directly transfer a US 401(k) or IRA to a Canadian RRSP. Unlike UK pensions (which have the QROPS system), US retirement accounts must either remain in the US, be withdrawn and contributed to an RRSP using the special deduction under paragraph 60(j) of the Income Tax Act (which does not require regular RRSP contribution room), or be drawn down over time. Consult a cross-border tax advisor to determine eligibility for the 60(j) transfer.
Will I be taxed twice on my 401(k) withdrawals?
No—the Canada-US Tax Treaty prevents double taxation. When you withdraw from your 401(k)/IRA, the US will withhold 15% on periodic payments (treaty rate). Note that lump-sum distributions may be subject to 30% mandatory withholding under US domestic law. Canada will tax the full amount as income, but you'll receive a foreign tax credit for the US tax paid. The result is you pay the higher of the two countries' rates, not both.
Is my Roth IRA tax-free in Canada?
Only if you file a treaty election under Article XVIII(7) with your first Canadian tax return. Without this election, Canada will tax the growth in your Roth accounts annually. Your contributions (basis) are never taxed, but the earnings would be. File the election—it's a one-time requirement.
Should I put US investments in my TFSA?
Generally no, especially if you're a US citizen or green card holder. The IRS does not recognize the TFSA as a tax-advantaged account. All TFSA gains are taxable to the US annually, and Canadian mutual funds trigger complex PFIC reporting. US persons should typically avoid TFSAs or hold only US-listed stocks/ETFs if they must use one.
What happens to my US Social Security if I live in Canada?
You can receive US Social Security benefits while living in Canada. Under the tax treaty, only 85% of your benefit is taxable in Canada (15% is exempt). The US-Canada Totalization Agreement also allows you to combine work credits from both countries to qualify for benefits.
Do I still need to file US taxes if I live in Canada?
If you're a US citizen or green card holder, yes—you must file US taxes every year regardless of where you live. This includes reporting your Canadian accounts (RRSP, TFSA, bank accounts) on FBAR and potentially Form 8938. Non-citizen, non-green card holders generally don't have US filing requirements after establishing Canadian residency.
