Company x is headquartered in the United States and has a Canadian branch. The branch maintains a "retirement contribution arrangement" ("RCA") which is essentially a non-qualified plan where the employer gets much of the benefits of a qualified plan, by being able to make a current deduction for contributions to the RCA, the participating employees are only taxed at the time they receive a distribution and while, in the RCA, the assets are protected from the employer's creditors. In addition, the assets are held by either a custodian or trustee. Assuming that the 90% resident test is satisfied, can a US employer elect to deduct contributions pursuant to Code Section 404A?
