U.S.-Canadian cross-border retirement planning.

• Author: Zink, William J.

The United States and Canada have a free trade agreement in place that allows the unrestricted movement of goods and services across their borders. This free mobility has created situations in which employees are transferred outside of their home country. Often while in the host country, the employees are earning pension benefits or making contributions into their own retirement accounts.

Once their foreign assignments end, some of these employees decide to retire in the host country. This decision raises certain questions about the treatment of retirement benefits that the employees may have earned throughout their careers.

* IRS Letter Ruling 8601047.

* IRS Letter Ruling 8633081.

* IRS Letter Ruling 8911001.

* Rev. Rul. 58-247.

* Rev. Rul. 56-446.

* Rev. Rul. 89-95.

* U.S.-Canada Treaty Article XVIII.

The following examples illustrate the application of these rules.

Example 1: T is a U.S. citizen who worked and resided in Canada. While there, T and his U.S. employer made contributions to his U.S. retirement account. T retires and remains in Canada. He begins to receive pension payments from his U.S. employer's pension plan.

In Canada, under the treaty, to the extent such benefits are partially excluded from U.S. taxation, such benefits must also be partially excluded from Canadian taxation.

Example 2: A is a Canadian citizen who worked and resided in the United States. While in the United States, he earned U.S. pension benefits. He returns to Canada and retires. After his retirement, A began receiving annuity payments from the U.S. pension plan.

Since A is a Canadian citizen and resident, he will not be taxed in the United States on the annuity payments he receives. However, he will be subject to a 15% U.S. withholding tax on these payments.

Example 3: B is a U.S. citizen who worked and resided in Canada. B retires and returns to the United States. He receives Canadian social security benefits. Under the treaty, the United States must exempt one-half of his Canadian benefits.

Example 4: Assume the same facts as in Example 3, except that B is a Canadian...
