Strategies for Canadians1 with U.S. retirement funds If you’ve ever worked in the United States, you may own an Individual Retirement Account (IRA) 2 or a U.S. qualified retirement plan, such as a 401(k) .3 Should you leave the funds in the U.S.? What happens if you repatriate the funds to Canada? Can you preserve the tax deferral until you retire? This article explores a few options, including how to transfer IRA and 401(k) plan balances to a Canadian Registered Retirement Savings Plan (RRSP) . Leaving the funds in the U.S. If you anticipate returning to live permanently in the United States sometime in the future, leaving the funds in your current U.S. plan may be a good option for you. However, consider checking with your plan administrator first, as there are many reasons a plan administrator may request that you take your money out. These reasons can range from legal constraints to mere administrative inconvenience, such as an account balance being too low. Funds in a U.S. IRA or 401(k) plan grow free of Canadian and U.S. income tax. If you choose to keep your IRA or 401(k) plan, the tax deferral is preserved. But, as with Canadian retirement plans, the tax deferral won’t last forever. With a U.S. IRA or 401(k) plan, you’re required to start taking distributions when you reach age 72. Periodic distributions from an IRA or 401(k) plan are subject to U.S. withholding tax at the rate of 15% .4 If you start taking distributions when you’re under age 59½, those periodic distributions will attract an additional 10% early withdrawal tax on top of the preceding rate. Periodic distributions from an IRA or 401(k) plan are also subject to Canadian income tax in the year that you receive them. They are treated as pension income. To prevent double taxation (i. e. Canadian plus U.S. taxation) of the same income, Canada should grant you a credit 5 for the tax you paid to the United States, including the 10% early withdrawal tax, if applicable. As a result, you pay no more, in aggregate, than customary Canadian income taxes on your IRA or 401(k) distributions.6 Maintaining an IRA or 401(k) plan entails keeping current on tax laws in two countries. As laws and rules evolve over time, we recommend you seek professional advice periodically. Repatriating the funds to Canada Some people feel more comfortable keeping their money in one place, and subject only to Canada’s laws. Others will wish to use their IRA or 401(k) plan assets to fund a short-term project. Whatever your reasoning, you may wish to liquidate your IRA or 401(k) plan and repatriate the funds to Canada. An IRA or 401(k) plan withdrawal is subject to U.S. withholding tax at the rate of 30% .7 If you’re under age 59½, the withdrawal will also attract the additional 10% early withdrawal tax, for a total of 40% . When you withdraw the balance of your IRA or 401(k), the [U.S. tax](U.S. tax) deferral ends. The only way to preserve the [U.S. tax](U.S. tax) deferral is to transfer the funds from your current U.S. plan to another U.S. qualified plan. The lump sum withdrawal out of your IRA or 401(k) plan will be subject to Canadian income tax in the year that you receive it. Since Canada should grant you a credit for the tax you paid to the United States, you should (as above) only pay the higher of the Canadian or the U.S. income tax, in aggregate.8 While the U.S. withholding tax may be treated as a final discharge [under U.S. law](under U.S. law), the Canada Revenue Agency (CRA) does not currently accept the U.S. withholding tax slip as adequate proof to grant you credit on your Canadian return for the U.S. tax paid. In practice, you should expect to file a U.S. income tax return and request a transcript9 from the Internal Revenue Service (IRS), to provide to the CRA. When you report your IRA or 401(k) withdrawal [on a U.S. tax](on a U.S. tax) return, [your U.S. tax](your U.S. tax) liability is computed at the U.S. graduated tax rates. If this liability tu

FAQs

If you keep your IRA or 401(k) in the U.S., how is tax handled in Canada and the U.S.?

U.S. growth is free of Canadian and U.S. income tax, but periodic distributions are subject to U.S. withholding tax and are taxed in Canada as pension income. Canada should grant a credit for U.S. tax paid to prevent double taxation, including early-withdrawal tax where applicable.

What happens when you repatriate IRA or 401(k) funds to Canada as a withdrawal?

A lump sum withdrawal triggers U.S. withholding tax, and if you are under age 59½ an additional early-withdrawal tax applies. The U.S. tax deferral ends, and the withdrawal is subject to Canadian income tax; credit eligibility depends on CRA accepting U.S. tax documentation supported by U.S. returns and transcripts.

How can an IRA or 401(k) be transferred to a Canadian RRSP to preserve tax deferral?

With proper planning, eligible lump sum withdrawals can create a one-time “special” RRSP contribution room that allows a deduction up to the withdrawal amount in the year of withdrawal. The transfer can be tax-neutral only if the U.S. tax paid on the withdrawal can be claimed as a credit against other Canadian income.
