Canadian Employer Pension (DB/DC) Received in the US: How Is It Taxed?
If you worked for a Canadian employer and earned a pension (defined benefit or defined contribution), and you now live in the US, the pension income is taxed differently from CPP and OAS. CPP and OAS receive exclusive-residence-country treatment under Article XVIII(1) of the treaty (taxable only in the US, no Canadian withholding). Your employer pension does not get that treatment. It is subject to Canadian withholding under Part XIII and is also taxable in the US, with the FTC preventing double taxation.
Canadian employer pensions paid to US residents are subject to Part XIII withholding at 15% (treaty rate for periodic payments under Article XVIII(2)). The US includes the full gross pension in income as pension/annuity income. The Canadian withholding generates an FTC on Form 1116. The 15% Canadian rate is usually less than the marginal US rate on the pension income, so the FTC is fully usable. Unlike CPP/OAS, the employer pension does not receive exclusive-residence-country treatment; both countries have a taxing right, with the FTC as the coordination mechanism.
How is a Canadian pension taxed if I live in the US?
Canada withholds 15% of the gross payment at source under the treaty rate, and the US includes the full gross amount in your income as pension or annuity income on your 1040. For current guidance, see IRS Publication 334 (Tax Guide for Small Business). The foreign tax credit on Form 1116 offsets the Canadian withholding against your US tax on that income, preventing double taxation. Because the 15% Canadian rate is typically below your US marginal rate, the FTC is fully usable and the net result is that you pay US tax at your marginal rate with no additional Canadian cost.
- This treatment applies to employer pensions (defined benefit plans and defined contribution plans) but not to CPP or OAS, which receive exclusive-residence-country treatment under a different paragraph of the treaty and are taxable only in the US.
- The distinction matters at filing time: CPP/OAS goes on the Social Security line, employer pensions go on the pension line, and the FTC mechanics differ because CPP/OAS produces no foreign tax to credit.
Treaty treatment: Article XVIII(2)
Article XVIII(2) of the Canada-US tax treaty provides that periodic pension payments (other than social security benefits covered by paragraph 1) may be taxed in both countries, but the source country’s tax is limited:
“Periodic pension payments arising in a Contracting State and paid to a resident of the other Contracting State who is the beneficial owner thereof shall be taxable only in that other State, except that the amount of any such payment that would not be included in taxable income in the first-mentioned State if the recipient were a resident thereof shall be exempt from tax in that other State.”
The practical effect: Canada can withhold on the pension (Part XIII), but the rate is limited to 15% for periodic payments under the treaty. Lump-sum payments may be subject to 25% (the treaty’s periodic-payment reduction does not apply to lump sums).
This is different from CPP/OAS (Article XVIII(1)), which gives exclusive taxing rights to the country of residence. The employer pension is covered by Article XVIII(2), which allows both countries to tax.
Canadian side: Part XIII withholding
When the pension administrator pays your monthly (or periodic) pension benefit, it withholds Part XIII tax. The default rate is 25%. With the treaty (Article XVIII(2)), the rate is reduced to 15% for periodic payments.
To get the 15% rate, file an NR301 (Declaration of Eligibility for Benefits Under a Tax Treaty) or NR5 (Application for Reduction of Non-Resident Tax) with the pension administrator. Without it, 25% is withheld.
RRIF parallel: RRIF payments get the same treatment. There’s no Part XIII exemption for a RRIF minimum withdrawal (ITA 212(1)(q) taxes RRIF payments); periodic RRIF payments up to the greater of twice the minimum or 10% of the plan’s value get the 15% treaty rate, the same as a periodic employer pension. The full amount of each periodic pension payment is subject to the 15% withholding.
Section 217 election: you can elect to file a Canadian return under Section 217, reporting your worldwide income and being taxed at graduated Canadian rates on the pension income. If your worldwide income is low enough that the graduated rate on the pension is below 15%, the Section 217 election saves money. If your worldwide income pushes the graduated rate above 15%, the flat 15% withholding is better.
Can I reduce the Canadian withholding on my pension?
Yes, through two routes. The first is filing an NR301 or NR5 form with the pension administrator to claim the treaty-reduced rate of 15% instead of the default 25%. This is straightforward and should be done as soon as pension payments begin. The second is the Section 217 election, which lets you file a Canadian return reporting your worldwide income and being taxed at graduated Canadian rates instead of the flat 15% withholding.
- If your worldwide income is low enough that the graduated rate on the pension falls below 15%, Section 217 saves money.
- For most retirees with moderate worldwide income (under roughly $50,000 CAD), Section 217 is worth running the numbers on. For higher-income retirees, the flat 15% is usually better.
US side: Form 1040
Report the full gross pension (before Canadian withholding) on line 5a/5b of Form 1040. The pension is ordinary income in the US, taxed at your marginal rate.
The Canadian withholding (15%) generates an FTC on Form 1116. The FTC category is “general” (not passive) for pension income. The FTC offsets US tax on the pension income dollar-for-dollar, subject to the IRC 904(a) limitation.
At most income levels, the US rate on pension income (10% to 37% depending on total income) exceeds the 15% Canadian withholding rate. The FTC is fully usable: the $15 of Canadian tax per $100 of pension offsets $15 of the US tax, and you pay the remaining US tax on the difference. There is no excess FTC to carry forward (because the Canadian rate is lower).
At lower income levels (taxable income under $48,475 for a single filer, where the US rate is 10-12%), the 15% Canadian rate may exceed the US rate. The excess Canadian tax ($3 per $100 if Canadian rate is 15% and US rate is 12%) carries forward as an excess FTC for up to 10 years.
Defined contribution plans
If your Canadian employer had a defined contribution (DC) pension plan (also called a money purchase plan), the treatment is the same as a defined benefit plan when distributions are periodic. If you take a lump-sum distribution or transfer the DC balance to a LIRA (Locked-In Retirement Account) or LIF (Life Income Fund), the withholding rules are:
- Lump-sum from DC plan: Part XIII at 25% (no treaty reduction for lump sums). You can file a Section 217 Canadian return to potentially reduce the rate.
- Periodic payments from a LIF: Part XIII at 15% (treaty rate for periodic payments).
- Transfer to LIRA (no distribution): no Part XIII withholding (no payment made to you; the transfer is between registered plans).
What about the pension income tax credit?
Canadian residents receive a pension income tax credit (ITA 118(3)) on the first $2,000 of eligible pension income. This credit is not available to non-residents. As a US resident receiving a Canadian pension, you do not get this credit. The Part XIII withholding (or Section 217 tax) is your Canadian tax, with no pension income credit offset.
Pension splitting
Canadian residents can split up to 50% of eligible pension income with a spouse (ITA 60.03). This reduces the marginal rate on the pension income. Non-residents cannot pension-split. If you are a US resident, the full pension is reported in your name and taxed at your rate in both countries.
On the US side, there is no pension-splitting mechanism. The full pension is your income.
What should I do next?
If you are receiving a Canadian employer pension in the US, confirm that the pension administrator is withholding at the 15% treaty rate (not the 25% default). File NR301 or NR5 if needed. Report the pension on your US return and claim the FTC on Form 1116. Consider whether Section 217 produces a lower Canadian rate than 15%.
