Pension Income Splitting Cross-Border: Canada-US

Canada allows spouses to split eligible pension income for tax purposes. The higher-income spouse can allocate up to 50% of qualifying pension income to the lower-income spouse, reducing the family’s combined tax. When one spouse lives in the US and the other in Canada, or when both spouses receive pensions from the other country, the interaction between splitting, treaty withholding, and FTCs makes the calculation more complex than a domestic split.

What income qualifies for splitting?

For taxpayers 65 and older, eligible pension income includes:

• Life annuity payments from a registered pension plan (RPP)
• RRIF and LIF payments
• Annuity payments from an RRSP
• Certain payments from a DPSP
• Foreign pension income (including US Social Security, US pensions, and IRA/401(k) distributions)

For taxpayers under 65, only life annuity payments from an RPP (or certain payments received because of the death of a spouse) qualify. RRIF and RRSP annuity payments do not qualify until the recipient turns 65.

US pension income (from a 401(k), IRA, or employer pension) received by a Canadian resident qualifies as eligible pension income for Canadian splitting purposes if the recipient is 65 or older and the income is included in their Canadian net income.

Both spouses live in Canada

When both spouses are Canadian residents, the split is straightforward. The higher-income spouse completes Form T1032, elects to transfer up to 50% of their eligible pension income to the lower-income spouse, and both report the adjusted amounts on their respective returns.

The pension income amount (the $2,000 non-refundable credit on line 31400) is available to both spouses on their respective shares. If the transferor splits enough to bring their pension income below $2,000, the transferee picks up the credit.

For US pensions received in Canada: the US-source pension is included in the transferor’s income, the FTC for any US withholding is claimed on the transferor’s return, and then the split is applied. After splitting, the transferee reports the allocated portion, but the FTC for US withholding stays with the transferor (it was the transferor’s income for foreign tax credit purposes). This can create an imbalance: the transferee pays Canadian tax on the split amount with no FTC, while the transferor has excess FTC (from claiming the credit on the full amount but paying Canadian tax on only half).

One spouse is a US resident

If one spouse is a US resident and the other is a Canadian resident at December 31, the Canadian splitting election is not available. ITA 60.03(1) requires that both the transferor and the transferee be residents of Canada in the taxation year and file a joint election. A US-resident spouse does not meet this test.

This means a Canadian resident married to a US resident cannot split Canadian pension income with their US-resident spouse. The entire pension is taxed in the Canadian resident’s hands, at their marginal rate, with no split.

If the couple later reunites in Canada (the US spouse moves back), splitting becomes available in the year both are Canadian residents at December 31.

What about the US side?

The US has no pension income splitting. Each spouse reports their own pension income on their own return (or on the joint return, attributed to the earner). There is no election to allocate income between spouses.

For a US citizen living in Canada who splits Canadian pension income with a Canadian spouse: the split is recognized on the Canadian return (Form T1032), and the transferee spouse reports the allocated portion for Canadian purposes. On the US return, the US citizen reports their full pension income (before the Canadian split), because the US does not recognize the ITA 60.03 election. The result is a mismatch: the Canadian return shows the split, and the US return shows the full amount. The FTC on the US return reflects the Canadian tax actually paid (which is reduced by the split), and the FTC may not fully absorb the US tax.

Does the OAS clawback interact with splitting?

OAS is not eligible pension income for splitting purposes. You cannot split OAS with your spouse. However, pension splitting can reduce the transferor’s net income, which can reduce or eliminate the OAS clawback. If splitting RRIF income with a spouse drops the transferor’s net income below the clawback threshold, the OAS is preserved.

This is one of the main reasons Canadian retirees use pension splitting: not for the split itself, but for the OAS clawback avoidance. For a cross-border couple where one spouse is in the US (and the OAS clawback does not apply to the US-resident spouse per the treaty exemption), the clawback avoidance benefit is only relevant for the Canadian-resident spouse.

What should I do next?

If both spouses are Canadian residents and one receives a foreign pension, run the split calculation with the FTC interaction before filing. If one spouse is a US resident, the split is not available on the Canadian return. For couples who are both in Canada but one is a US citizen, model the US/Canadian tax mismatch before electing the split.
