You're moving north and you've got a 529 set aside for your kid's education. Here's what CRA does with it, why the treaty doesn't help, what your options actually cost, and what gets reported. Every rule below is traced to the statute, the treaty, or the agency's own page.
A 529 plan exists because of one US statute. Section 529 of the Internal Revenue Code creates a "qualified tuition program" operated by a state or eligible educational institution, and exempts it from federal income tax. The growth compounds tax-free, and distributions used for qualified education expenses come out tax-free too. It's a powerful piece of the US tax code, and it has no equivalent in Canada's Income Tax Act.
Canada has its own education savings vehicle, the RESP, and it works differently. But the Income Tax Act doesn't contain a provision that says "if another country calls something tax-exempt, so do we." CRA taxes Canadian residents on worldwide income under section 2 of the ITA, and an American account that the IRC exempts from US tax doesn't get a parallel exemption from Canadian tax. The exemption is statutory, US-only, and non-portable.
No. Article XVIII of the Canada-US Tax Convention covers pensions, annuities, and social security benefits. It's the article that protects RRSPs, 401(k)s, and IRAs from double taxation, and it works because both countries agreed to defer tax on those specific retirement vehicles.
A 529 plan is not a pension. It's not a retirement arrangement. It's an education savings plan, and it doesn't appear anywhere in Article XVIII, in the treaty's definitions, or in any other article of the convention. There's no treaty mechanism that tells CRA to leave the growth alone.
This is a genuine gap. The treaty was last substantially revised in the Fifth Protocol (2007), and education savings plans weren't addressed then either. Unlike an RRSP or 401(k), where both countries have agreed on deferral, a 529 sits in a space the treaty simply doesn't cover.
There's no published CRA ruling that addresses 529 plans by name, which is itself part of the problem. What IS clear is that Canada taxes residents on worldwide income, the treaty doesn't carve out an exception, and practitioners consistently report that CRA does not recognize the tax-free wrapper.
The growth in your 529 is part of your Canadian income. The question is how CRA classifies the plan, and that classification determines the calculation.
Practitioners have identified two main possibilities. One is that the 529 is treated as offshore investment fund property under section 94.1 of the ITA, which imputes income at the prescribed rate times your cost in the plan, regardless of actual returns. The other is that it's treated as a foreign trust, which brings its own income inclusion rules and reporting obligations.
Either way, the income shows up on your Canadian return while the account is open. And either way, the classification question matters because the tax calculation, the forms, and the penalties for getting it wrong are all different depending on which bucket CRA puts it in.
If you're a US citizen or green card holder, you remain a US tax person after the move. Your 529 still grows tax-free for US purposes, qualified distributions are still tax-free on the US return, and you can still contribute. The problem is entirely on the Canadian side.
| While you live in the US | After you move to Canada | |
|---|---|---|
| Growth | Tax-free under IRC 529(a). | Still tax-free for US purposes. Likely taxable annually by CRA, since the treaty doesn't cover it and the ITA has no recognition provision. |
| Qualified distributions | Tax-free: no income tax, no penalty on the earnings. | Still tax-free for US purposes. Canadian treatment depends on whether growth was already picked up on your T1. |
| Non-qualified distributions | Earnings taxed as ordinary income, plus a 10% additional tax. | Same US treatment. Canadian implications depend on how CRA classified the account. |
| Reporting | 1099-Q from the plan provider when distributions are taken. | T1135 if total specified foreign property exceeds $100K CAD. Possible trust reporting depending on CRA classification. |
| Contributions | Allowed; no federal deduction (some states give a deduction or credit). | Still allowed for US purposes. CRA doesn't recognize the wrapper, so growth on new money faces the same Canadian treatment. |
Yes, if the Canadian school is an "eligible educational institution" under the Higher Education Act. Section 481 of that Act defines the term, and the Department of Education maintains a list of eligible foreign schools, each with a Federal School Code. Most major Canadian universities have one: the University of Toronto, McGill, UBC, and dozens of others participate.
Distributions from a 529 used for tuition, fees, books, supplies, and equipment required for enrollment at an eligible institution are qualified higher education expenses under section 529(e)(3) of the IRC. Those come out tax-free on the US side, with no 10% penalty, the same as if the beneficiary attended a US school.
This matters for planning. If the beneficiary is going to attend a Canadian university anyway, the 529 can still do what it was built to do on the US side. The complication is only on the Canadian side, and only while the account is open and growing.
The 529 keeps growing tax-free for US purposes, and you can use it for qualified expenses at eligible schools in either country. The cost is the Canadian reporting obligation and the likely annual Canadian tax on the growth while you're a resident. If the beneficiary is close to college age and the plan will be drawn down in a few years, this can make sense, since the Canadian reporting window is short.
Contributions come out tax-free because they went in with after-tax dollars. The earnings come out as ordinary income and take a 10% additional tax under section 529(c)(6). There is no exception to the penalty for moving abroad, for renouncing citizenship, or for becoming a non-resident. The exceptions in the statute are limited to the beneficiary's death, disability, receipt of a scholarship, or attendance at a US military academy.
If you took a state tax deduction for your contributions, the state may claw that back on a non-qualified withdrawal. New York, Virginia, and Illinois all recapture previously deducted amounts, and each state's rules are slightly different.
Since January 2024, the SECURE 2.0 Act allows a rollover from a 529 to a Roth IRA for the benefit of the same designated beneficiary. There are three gates: the 529 account must have been maintained for at least 15 years, each year's rollover can't exceed the Roth IRA contribution limit for that year (currently $7,000 for someone under 50), and the lifetime cap is $35,000. Contributions being rolled over must have been in the plan for at least five years. The regular Roth IRA income limits don't apply to this rollover.
For someone moving to Canada with a long-tenured 529 and a beneficiary who's years away from school, this can be a way to redeploy some of the money without the 10% penalty. But it's annual-limited, so drawing it down takes time, and you'd want to start before the Canadian reporting kicks in rather than after.
A 529 allows a change of account owner, and some plans allow it as a straightforward administrative request. Moving the ownership to a US-resident parent, grandparent, or sibling takes the account out of your Canadian reporting picture entirely. The catch is that you give up control of the money: the new owner decides when and how it's used. There's also a gift tax question on the US side if the transfer isn't structured carefully.
If the 529 is small and the beneficiary starts school next year, you probably don't need us. Keep the plan, use it at the Canadian university, and deal with one or two years of Canadian reporting.
The files that need a CPA are the ones with six-figure balances, a beneficiary years away from college, a plan that's held long enough for the Roth rollover, or a mix of 529s across multiple states with different recapture rules. Those need the two-country picture worked out before anything moves.

If your total specified foreign property exceeds $100,000 CAD in cost at any time during the year, you have to file Form T1135 under section 233.3 of the ITA. The 529 is a US-situs trust, not personal-use property, so it counts toward that threshold alongside any US brokerage accounts, IRAs, and other foreign holdings you have.
The threshold is based on cost (what you put in), not fair market value, and it's measured in Canadian dollars. If your contributions converted to CAD don't clear $100,000, and you don't have other specified foreign property that pushes you over, T1135 doesn't apply.
Depending on how CRA classifies the 529 (as a foreign trust rather than simply as foreign property), there may also be a trust reporting requirement on Forms T1141 or T1142. That classification question isn't resolved by a published CRA ruling specific to 529 plans, so it's worth raising with your preparer rather than guessing.
The mirror problem exists. Canada's Registered Education Savings Plan is not recognized by the IRS, the treaty doesn't cover it, and the US will tax a Canadian RESP held by a US tax person. The RESP's growth is taxable on the US return, and the plan may be treated as a foreign trust for US purposes, with Forms 3520 and 3520-A to match.
The RESP has one feature the 529 doesn't: the Canada Education Savings Grant (CESG), where the government matches 20% of the first $2,500 contributed per year, up to a lifetime cap of $7,200. That grant money doesn't cross the border either, and an RESP collapse triggers a CESG repayment to the government.
Neither country's education savings plan travels well, for the same structural reason: each one was built as a domestic tax incentive, and neither treaty partner agreed to extend recognition to the other's.
