Moving between Canada and the United States is an exciting adventure—whether for work, family, or retirement. But when it comes to your retirement savings, things can get tricky. Defined benefit (DB) pensions, like the Canada Pension Plan (CPP) or Quebec Pension Plan (QPP), and U.S. qualified plans such as 401(k)s, aren’t as portable as your suitcase. The good news? The U.S.-Canada Tax Treaty helps smooth the way, preventing double taxation and allowing some tax-deferred growth. This guide will walk you through the process with a thorough yet digestible breakdown, covering portability, lump-sum options, foreign withholding taxes, tax credits, and the all-important timing of your move. This article is designed to help you work with a cross-border financial planner to secure your financial future across borders.

This guide is divided into easy-to-follow sections, using real-world examples to make it relatable. Whether you’re a Canadian planning on retiring in a warmer climate or an American heading north to enjoy a Canadian lifestyle, understanding these rules can save you thousands in taxes and headaches. Let’s dive in with the help of cross-border wealth management expertise.
Understanding the Basics: What Are These Plans?
Before we cross borders, let’s clarify the plans in question with insights from a cross-border tax planning perspective.
- CPP, OAS & Social Security: These are all considered benefits under the social security legislation of Canada and the U.S. They are only taxable in the country of residence. If you are receiving U.S. social security while a Canadian resident, it is only 85% taxable. In receiving any of these while in the U.S. they are taxable up to 85% depending on your income from other sources. Contributions are a fixed percentage of your eligible earned income and benefits are determined at the time of retirement.
- Defined Benefit (DB) Pensions: These are “promised payout” plans that provide a predictable monthly benefit based on factors such as earnings and years of service, typically starting around age 60. In both Canada and the U.S., DB plans are mostly offered by employers, though they have become increasingly rare as organizations shift toward Defined Contribution (DC) plans, where investment risk is borne by the individual rather than the employer. While the structure and purpose are similar in both countries, U.S. DB plans often integrate with Social Security benefits, whereas Canadian DB plans may coordinate with CPP/QPP.
- Defined Contribution Plans like RRSPs or 401(k)s: These are more like savings accounts where you (and often your employer) contribute. In the U.S., 401(k)s grow tax-deferred, with options for traditional (pre-tax) or Roth (after-tax) versions. In Canada, RRSPs grow tax-deferred.
- FTQ (Fonds de solidarité FTQ): This Quebec-specific fund is a labor-sponsored investment vehicle, often held within an RRSP (Registered Retirement Savings Plan) for the RRSP contribution deduction and the additional FTQ tax credits. It’s not a pure pension but offers retirement savings with tax benefits and can be redeemed under certain conditions.
Government plans like CPP/QPP can’t be “transferred” like private ones, but treaties coordinate benefits. Each system was designed with its own tax advantages and withdrawal rules, creating a puzzle with you trying to fit pieces from one country into another’s framework. This is where cross-border wealth management strategies and the knowledge of a cross-border financial planner really pay off.
Let’s examine two different scenarios.
Scenario 1: Canadians Moving to the U.S. with CPP, QPP, or FTQ
Picture this: You’re a Canadian engineer from Quebec with years of contributions to QPP and FTQ shares in your RRSP. A job offer in Seattle pulls you south. What happens to your retirement savings?
Portability: Can You Take It with You?
For public plans like CPP and QPP, direct transfers to a U.S. IRA aren’t possible. Instead, the U.S.-Canada Totalization Agreement kicks in. This pact combines your work credits from both countries to qualify for benefits. For example, if you’ve worked 8 years in Canada and 2 in the U.S., those Canadian years count toward U.S. Social Security eligibility (which requires 10 years). You can receive your CPP/QPP payments anywhere in the world, including the U.S., without losing eligibility. Unlike other benefits tied to residency, these pensions are based purely on your contributions towards them during your working years.
Side note: Service Canada can even direct deposit your monthly payments directly into a U.S. bank account in USD.
For FTQ held in an RRSP, you can’t directly roll it into a U.S. IRA. However, you can keep the RRSP intact as a Canadian non-resident. Under the Canada-U.S. treaty and IRS Revenue Procedure 2014-55, U.S. taxation of undistributed income in RRSPs/RRIFs can generally be deferred until distribution. To use treaty benefits, use Form 8833 attached to your tax return, and consult with a cross-border tax professional. Not all U.S. states honor the Canada – U.S. Tax Treaty. In states like California and Kansas, the income earned in your RRSP is currently taxable for state purposes. Upon leaving Canada, FTQ lets you redeem shares held for over two years without penalties, treating it as a permanent emigration withdrawal. If the FTQ is held in an RRSP, the withdrawal will stay there and be reinvested until you take an RRSP distribution.
Lump-Sum Options: Cash Out or Annuity?
CPP and QPP don’t offer lump sums for standard retirement—benefits come as monthly payments. You can start reduced payments at age 60 or full payments at age 65. For special cases like disability, limited lump sums exist, but relocation doesn’t trigger them.
FTQ is more flexible: You can take a lump-sum withdrawal upon emigration, but it’s fully taxable in Canada if from an RRSP. This might make sense if you need cash for your U.S. move, but it’s important to plan for the tax implications with a cross-border wealth advisor.
Foreign Withholding Taxes: Who Takes a Cut?
Under Article XVIII of the Canada – U.S. Tax Treaty, CPP/QPP, OAS and U.S. Social Security income are taxable only in the taxpayer’s country of residence. Source-country non-resident withholding taxes are not required.
For FTQ or RRSP lump sum distributions, Canada applies 25% withholding to non-residents. The treaty doesn’t reduce this for one-time payouts—only periodic payments get a 15% withholding rate. So, a $100,000 lump sum distribution could see $25,000 withheld upfront.
Tax Credits: Reducing Double Taxation
As a U.S. resident, you’ll report Canadian pension income on your U.S. tax return. If Canada withheld tax, claim a Foreign Tax Credit (FTC) on IRS Form 1116 to offset U.S. liability on the same income. For example, if Canada takes $5,000 in tax on a $20,000 distribution, you credit that against your U.S. tax bill on that amount of foreign-sourced income. Cross-border tax planning is key here.
Timing Your Move: When to Act
- Pre-Move: Boost contributions to maximize Totalization credits. Defer any withdrawals to avoid Canadian tax while still a resident.
- During the Move Year: File as a dual-status taxpayer—U.S. non-resident up to the date of move and U.S. resident post-move. Indicate treaty deferral on form 8833 for RRSP/FTQ on the first U.S. return to keep growth tax-free in the U.S, at least for federal purposes.
- Post-Move: Start benefits in the U.S. when it makes sense for your situation. Are you full retirement age? Are you still working and contributing to Social Security? Note the 2025 Windfall Elimination Provision (WEP) was recently repealed, which means your U.S. Social Security won’t be reduced by CPP receipts. For FTQ, withdraw after settling to claim emigration status.
Example: Sarah, a Quebec resident with QPP and FTQ, moves to Texas. She keeps her RRSP, indicates treaty deferral on her first U.S. tax return, and receives QPP, taxable as if it was U.S. Social Security, in the U.S.
Scenario 2: Americans Moving to Canada with 401(k)s or DB Pensions
Now flip the script: You’re a U.S. citizen with a 401(k) from your tech job, heading to Toronto for a new role. As a U.S. citizen or Green Card holder, you’ll file taxes in both countries, but Canada becomes your primary tax home. Having a cross-border wealth management strategy is essential to navigate this transition effectively.
Portability: Transferring South to North
For 401(k) and 403(b) Plans you have three options:
- Leave it where it is. This allows your assets to grow tax-deferred thanks to the Canada-U.S. Tax Treaty, however managing it while out of the country is not possible. This is the simplest solution but not ideal if you plan on moving out of the U.S.A. for the long-term.
- Roll it over into an IRA. Prior to leaving the U.S. you can elect to rollover your 401(k) plan into an IRA. Doing this allows for greater flexibility and can be managed by a cross-border wealth advisor who is licensed in both countries.
- Transfer it to an RRSP. This is an option, however due to high U.S. withholding and Canadian tax on withdrawals it tends to be sub-optimal. This can be done without having or losing RRSP contribution room thanks to the treaty. This keeps growth deferred in Canada.
DB pensions can’t directly transfer to an RRSP, but you can leave them in the U.S. plan with treaty-protected deferral. If your employer allows, commute the value to a lump sum and roll to RRSP with guidance from a cross-border financial planner.
Lump-Sum Options: Flexibility North of the Border
Distributions from 401(k)s and IRAs are taxable in the U.S. at 15% under the Treaty. Those distributions will be taxable in Canada as well but sourced to the U.S., and the 15% U.S. tax can be used as a foreign tax credit on your Canadian return. If your 401(k) or IRA has already been transferred to an RRSP, then it will be reportable to the U.S., but foreign tax credits should shield it completely from U.S. taxation. DB plans often offer lump-sum buyouts, taxable in the U.S., but potentially transferable to RRSP at commuted value.
Foreign Withholding Taxes: U.S. Takes First Bite
The U.S. withholds 10% on pension plan distributions to U.S. citizens or Green Card holders living abroad. Roth versions are tax-free in the U.S., but there is still a nominal refundable withholding on withdrawals. Presuming that the correct Competent Authority elections have been made for the Roth and the distribution is ‘qualifying’, the income escapes taxation in both countries, once the tax returns are filed. Cross-border tax planning can ensure this favorable result.
Tax Credits: Double Duty Relief
Claim Canadian FTC on your T1 return for U.S. taxes paid, avoiding double taxation. As a U.S. citizen, use Form 1116 on U.S. returns for Canadian taxes.
Timing Your Move: Strategic Planning
- Pre-Move: Consider rolling over your 401(k) into an IRA, then either convert or transfer it to an RRSP. Alternatively, work with a cross-border, dual-licensed financial advisor while you are still a U.S. resident. Either option allows you to minimize having to pay higher Canadian tax rates on conversions. Whenever possible, it’s also wise to defer distributions.
- During the Move Year: Dual-status filing; time lump sum distributions before move for U.S.-only taxation with a cross-border wealth advisor.
- Post-Move: Use Form W-9 to indicate U.S. citizenship and avoid the higher U.S. withholdings on non-resident aliens.
Example: John, a U.S. citizen with a 401(k), moves to Vancouver. He rolls it to an IRA pre-move, transfers to RRSP largely tax-free, and claims FTC for U.S. withholdings on later withdrawals with cross-border wealth management support.
Key Comparisons and Practical Tips
To make sense of it all, here’s a quick comparison table:
| Aspect | Canadian to U.S. | U.S. to Canada |
|---|---|---|
| Portability | CPP/QPP: Benefits abroad; no transfer. FTQ: Redeem or keep. | 401(k)/DB: Roll to IRA/RRSP tax-deferred. |
| Lump-Sum | Limited for public plans; yes for FTQ. | Yes, but taxable unless transferred. |
| Withholding | 25% Canada (0-15% treaty). | 15% treaty for periodic, 25% treaty for lump-sum. 30% U.S. without Treaty |
| Tax Credits | U.S. FTC. | Canadian FTC. |
| Timing | Defer post-move. | Convert pre-move. |
Practical Tips:
- Hire Experts: Always work with a cross-border wealth advisor and tax professional. Navigating forms, like the CRA’s T1 and IRS’s 1040, can be overwhelming when doing it alone.
- Avoid Double Taxation Pitfalls: Time conversions to lower-tax years; use treaty elections early with cross-border tax planning.
- Inflation and Currency: Factor in exchange rates—CAD-USD fluctuations can erode value.
- Recent Changes: The 2025 WEP repeal benefits dual earners. Watch for treaty updates with a cross-border financial planner.
