Simple US tax guide for Canadian retirement plans
What this guide covers for retirement tax planning in Canada
Cross-border retirement planning gets tricky fast because the Canadian name of a plan does not automatically tell you how the IRS will treat it. A plan can be tax-friendly in Canada, fully reportable in the US, or both at the same time.
This guide walks through the main plans and benefits US taxpayers most often ask about: CPP, OAS, RRSPs, RRIFs, and TFSAs. It also explains where the US-Canada treaty helps, where foreign tax credits can reduce double taxation, and where extra reporting may still apply.
Canadian retirement plans: quick comparison
This one-screen table gives the big picture before we get into the details.
| Plan | How Canada treats it | Typical US treatment | Treaty angle | Common reporting note |
|---|---|---|---|---|
| CPP / OAS / QPP | Government benefits, taxable under Canadian rules depending on residence and withholding | For a US resident, generally treated like US Social Security benefits; up to 85% may be taxable depending on total income | Treaty rules are central | US residents commonly report these on Form 1040 lines 6a and 6b |
| RRSP | Deductible contributions in Canada; tax-deferred growth | Generally eligible for tax deferral until distribution | Treaty-supported, with Form 8891 no longer required | Distributions still go on the US return; FBAR / Form 8938 may still matter |
| RRIF | Payout phase of RRSP savings; minimum withdrawals apply | Generally follows RRSP treatment | Treaty-supported | Distributions usually reported on the US return; Canadian tax may support a foreign tax credit |
| TFSA | No deduction for contributions; growth and withdrawals can be tax-free in Canada | No broad treaty protection; income and reporting can be more complicated | Limited compared with RRSP / RRIF | May require review for PFIC, foreign trust, FBAR, and Form 8938 issues depending on facts |
Is CPP taxable? A plain-English guide to Canada Pension Plan tax
The Canada Pension Plan, or CPP, is Canada’s public retirement system for workers. For 2025, the base employee and employer CPP rate is 5.95%, the basic exemption stays at CAD 3,500, and the maximum base contribution is CAD 4,034.10 each, according to the CRA. Source: CRA CPP contribution rates, maximums and exemptions.
For most tax planning questions, the contribution rate is not the hard part. The real issue is how Canada pension plan US taxes work after you retire, especially if you live on one side of the border and receive benefits from the other.
If you live in the US
Under the treaty, benefits paid under CPP, QPP, and OAS to a US resident are generally treated as US Social Security benefits for US tax purposes. That means they are commonly reported on Form 1040, lines 6a and 6b, and up to 85% can become taxable depending on your overall income.
See IRS Form 1040 instructions.
If you live in Canada
For a US citizen or green card holder who is resident in Canada, treaty treatment often shifts the taxing right on CPP and OAS to Canada. In practical terms, that usually means the income is taxed on the Canadian side, while the US return needs to reflect the treaty position correctly.
Old Age Security and are pensions taxed in Canada
Old Age Security, or OAS, is separate from CPP. You can qualify for OAS based on age and residency history even if you did not build up CPP contributions through work.
A key OAS rule to keep current is the recovery tax. For the 2025 tax year, the CRA says the OAS recovery-tax threshold is CAD 93,454, and the repayment rate is 15% of income above that threshold.

RRSPs and RRIFs for tax planning for retirement Canada
If you are a US taxpayer in Canada, RRSPs and RRIFs are often more predictable than a TFSA. An RRSP is a registered retirement savings plan. A RRIF is usually the payout phase that your RRSP eventually converts into.
In Canada, RRSP contributions can reduce taxable income, and growth inside the plan is tax-deferred. By the end of the year you turn 71, the RRSP generally must be converted to a RRIF or another payout option.
For the core IRS treatment, see Revenue Procedure 2014-55, which removed the old Form 8891 election requirement for eligible RRSP and RRIF owners.
How RRSP and RRIF distributions are usually taxed in the US
The favorable point is that RRSPs and RRIFs generally qualify for tax deferral. The important limit is that distributions still need to be reported on the US return when you take money out, and any Canadian tax paid may support a foreign tax credit.
This is why the answer to is Canadian pension taxable in US is often “yes, but not always in the same way, and treaty relief may prevent double tax.” A government benefit, a private pension, and a RRIF withdrawal can all land differently on the return.
| Feature | RRSP | RRIF | Why it matters for US taxpayers |
|---|---|---|---|
| Main purpose | Save for retirement | Draw retirement income | Helps explain why one plan receives contributions and the other pays distributions |
| Contributions | Usually allowed, subject to Canadian limits | No new contributions once converted | Important for Canadian deduction planning |
| Withdrawals | Possible, usually taxable | Minimum annual withdrawals apply | Drives annual US reporting and possible foreign tax credit use |
How to report Canadian pension on US tax return
This is where many expats lose time. The right entry point depends on what the payment actually is. CPP, QPP, and OAS paid to a US resident are commonly treated like Social Security for US reporting. Other foreign pension or annuity payments may follow different rules.
The IRS also notes that foreign pension and annuity income may be fully or partly taxable even if you do not receive a US information form. See the IRS page on foreign pension and annuity distributions.
| Income type | Common US treatment | Typical reporting starting point | Extra review point |
|---|---|---|---|
| CPP / OAS / QPP for a US resident | Usually treated like US Social Security | Form 1040 lines 6a and 6b | Taxable portion can be up to 85% depending on total income |
| RRSP / RRIF distributions | Usually reported as pension-type income on the US return | Review the Form 1040 pension/annuity framework and your software inputs | Canadian withholding may support a foreign tax credit on Form 1116 |
| Canadian private pension or annuity | Facts matter | Review general foreign pension rules | Treaty position may differ from CPP / OAS treatment |
| TFSA income | No simple one-line answer | Depends on the assets and reporting profile | PFIC, foreign trust, FBAR, and Form 8938 questions may apply |

Canada pension plan tax forms and slips you may see
The Canadian slip you receive does not always match the US form you will use, but it still matters. Many expats see T4A(P) for CPP, T4A(OAS) for OAS, or NR4 slips in non-resident situations.
For Canadian source documents, review the CRA non-resident income tax package and the CRA NR4 guide.
TFSAs: where retirement tax planning Canada gets more complicated
A TFSA is attractive in Canada because qualified growth and withdrawals can be tax-free there. But for a US taxpayer, the TFSA does not have the same broad treaty support that RRSPs and RRIFs enjoy.
The annual TFSA dollar limit is now far above the figures in the old article. The CRA shows a CAD 7,000 TFSA dollar limit for 2025 and again for 2026.

Why TFSAs need extra US review
The account itself may trigger multiple questions at once. If the TFSA holds Canadian mutual funds or ETFs, PFIC reporting can become an issue. Depending on the facts, foreign trust reporting questions can come up too, although the rules are no longer as simple as saying every TFSA always requires Forms 3520 and 3520-A.
The IRS says Forms 3520 and 3520-A are not required for RRSPs and RRIFs under Rev. Proc. 2014-55, and certain tax-favored foreign trusts may also qualify for relief under Rev. Proc. 2020-17. See also the IRS foreign trust reporting overview and the current Form 3520 instructions.

Retirement tax planning in Canada: practical takeaways for US taxpayers
For many expats, the most practical ranking looks like this: RRSPs and RRIFs are often easier to defend and administer than TFSAs, while CPP and OAS need the right treaty treatment based on where you live when you receive them.
That does not mean every case is identical. A US resident living in Florida and receiving CPP has a different reporting path from a dual filer living in Toronto who needs to coordinate Canadian taxation, US filing, exchange rates, and foreign tax credits.
FAQ
Usually yes, but it is commonly treated like US Social Security for US tax purposes rather than like an ordinary foreign private pension. The taxable portion can be up to 85% depending on total income, and the starting point is commonly Form 1040 lines 6a and 6b.
If you are resident in Canada, CPP is generally taxed on the Canadian side, and the treaty position on your US return has to match that residence-based rule. Do not rely on the same treatment that would apply to a US resident.
Start by identifying the Canadian slip you received, such as T4A(P), T4A(OAS), or NR4. Then map the payment to its US tax character – Social Security-style benefit, pension, annuity, or something else – instead of assuming the Canadian slip name tells you exactly where it belongs on Form 1040.
Sometimes both countries have a connection to the income, but the treaty and the foreign tax credit are designed to reduce double taxation. The key is to identify the type of payment and your tax residence before deciding how to report it.
In many cases, RRSPs and RRIFs are more predictable than TFSAs from a US compliance perspective. But the best answer still depends on where you live, what assets you hold, and whether you expect to stay in Canada or move back to the US.
No blanket answer is safe anymore. The IRS has exemptions for certain tax-favored foreign trusts, so the better approach is to review the specific TFSA structure and the assets inside it before concluding that those forms are or are not required.
