The Spousal RRSP for US Citizens in Canada: Who Deducts, Who Defers, Who Reports, and What the Three-Year Rule Does

Short version: Spousal RRSP After Moving to the U.S.

A spousal RRSP separates the contributor from the annuitant: one spouse contributes and deducts, the other owns the plan and is taxed on withdrawals. For Canadian purposes it is an income-splitting tool. For US purposes, the treaty deferral attaches to the annuitant (the plan's owner), the reporting attaches to whoever has a financial interest, and the contributor's non-deductible US contribution creates basis in a plan they do not own. Which spouse is the US person decides how each of these plays out.

Key takeaways

• Canadian mechanics: the contributor deducts the contribution against their own income within their own RRSP room; the annuitant spouse owns the plan; withdrawals are taxed to the annuitant, except that withdrawals within three calendar years of any spousal contribution are attributed back to the contributor (the three-year rule).
• US person is the annuitant: the plan is the US person's; Article XVIII(7) and Revenue Procedure 2014-55 defer US tax on the growth; the plan is on the US person's FBAR and Form 8938; withdrawals are taxable to the US person in the US (less any basis) with a foreign tax credit for the Canadian tax.
• US person is the contributor: the contribution is not deductible in the US; the US person has no ownership of the plan and, in the usual analysis, no financial interest for FBAR purposes; the growth is the Canadian spouse's and not US-reportable; the US person's non-deductible contribution is effectively a gift to the spouse for US purposes (within the annual limit for a non-citizen spouse) and creates no US basis for the US person because they will not receive the withdrawals.
• Both are US persons: the annuitant reports and defers; the contributor's contribution is a gift between spouses (unlimited between US citizens); the annuitant's basis includes the contributor's contributions if the couple treats them as the annuitant's non-deductible contributions.
• The three-year rule taxes an early withdrawal to the contributor in Canada; for US purposes the withdrawal is still the annuitant's distribution from their plan, creating a mismatch in who reports it in each country.

The Canadian rule

A spousal RRSP is an RRSP under which the annuitant's spouse or common-law partner makes contributions. The contributor's deduction is limited by the contributor's own RRSP deduction limit; the annuitant's room is unaffected. On withdrawal, the annuitant is taxed, which shifts income from a higher-earning contributor to a lower-earning annuitant in retirement. The attribution rule: if the annuitant withdraws in a year in which, or in the two preceding years, the contributor made a spousal contribution, the withdrawal is taxed to the contributor up to the amount of those contributions.

US person as annuitant

A US citizen whose Canadian spouse contributes to a spousal RRSP in the US citizen's name owns a registered plan. The treaty deferral applies to the US citizen as the plan's owner; the plan is reported on the US citizen's FBAR and Form 8938; withdrawals are pension income to the US citizen in the US, with a foreign tax credit for the Canadian tax (which is also the annuitant's, except under the three-year rule). The Canadian spouse's contributions were not the US citizen's contributions, so they do not create US basis for the US citizen unless the US citizen treats them as their own non-deductible contributions; the conservative position is that basis arises only from the US person's own contributions. If the three-year rule taxes an early withdrawal to the Canadian contributor, the US citizen still has a US distribution from their plan with no matching Canadian tax to credit.

US person as contributor

A US citizen who contributes to a spousal RRSP in their Canadian spouse's name deducts the contribution in Canada and gets no US deduction. The plan belongs to the Canadian spouse; the US citizen has no ownership and, under FinCEN's definition of financial interest (owner of record or holder of legal title), no FBAR obligation for it, though a US citizen with online access and withdrawal authority may have signature authority. The plan's growth is the Canadian spouse's and is not reported on the US citizen's 1040. For US gift tax purposes, the contribution is a transfer to a non-citizen spouse; annual contributions within the non-citizen spouse limit (about $190,000) need no Form 709. If the three-year rule attributes a withdrawal to the US contributor in Canada, the US citizen has Canadian income (taxable in Canada) with no US inclusion (the distribution was the spouse's), creating a Canadian tax that the US citizen cannot credit because there is no US tax on the same income.

Both US persons

The annuitant owns and reports the plan; the treaty deferral applies; withdrawals are the annuitant's US income. The contributor's contributions are gifts between US-citizen spouses (unlimited). Whether the annuitant's US basis includes the contributor's contributions is not settled; the practical approach is to document the contributions and take a consistent position.

Planning

• Where one spouse is a US person and the other is not, having the Canadian spouse be the annuitant of any spousal RRSP funded by the US person keeps the plan and its growth off the US return entirely, and the contribution is within the spousal gift limit.
• Where the US person is the lower earner and will be the annuitant, the plan is on the US person's return, but the deferral applies and the withdrawals will be at a lower Canadian rate.
• Avoid withdrawals within the three-year window; the attribution mismatch complicates both returns.
• The contributor's RRSP room is the limit; a couple with one high earner uses the spousal plan to build the low earner's retirement income.

Worked example

A Toronto couple: he is a US citizen earning $220,000 CAD; she is Canadian earning $50,000 CAD. He contributes $20,000 a year to a spousal RRSP in her name.

• Canada. He deducts $20,000 against his income (saving about $10,700); the plan is hers; withdrawals in retirement are hers at her rate (unless within three years of a contribution).
• US (his return). No deduction. Not his plan: not on his FBAR or Form 8938 (no financial interest); the growth is not his income. The $20,000 is a gift to a non-citizen spouse within the annual limit; no Form 709.
• Retirement. She withdraws; Canadian tax at her rate; nothing on his 1040 (her plan, her income; she is not a US person).
• Contrast. If she were the US citizen and he the Canadian contributor: the plan is on her FBAR and Form 8938; the growth is deferred under the treaty; withdrawals are her US pension income with a credit for the Canadian tax; no US basis from his contributions under the conservative view.

Practitioner note

The spousal RRSP is the cleanest way for a mixed couple to keep retirement savings off the US return: the US person contributes and deducts in Canada, the Canadian spouse owns the plan, and nothing about the plan's growth or withdrawals reaches the 1040. The three-year rule is the trap; we calendar it from the last contribution.
