I also put foreign pensions (UK, Switzerland) on Line 21. Yes read the tax treaty; lots of good info in those. Yes foreign tax credit is likely. If the ONLY holding is a pension, it is likely that the FBAR (FACTA; whatever they're calling it this week) is NOT actually required. Pensions are paid out to recipients but are generally NOT in the person's control, segregated by their name, and most likely there is no "account balance" the person ever knows of. Those disclosure requirements are for accounts the client has *some* measure of control over. For pensions, the only control they likely have is submitting a new address to send payment to; there is NO control over the account itself. So, no reporting requirement.
