Israel has several types of mandatory and voluntary retirement savings accounts, including Keren Hishtalmut (a short-term savings fund used as a supplement to wages) and various pension kupot (pension funds). The US-Israel tax treaty contains a pension article that provides some protection against double taxation, but the specific treatment of each type of Israeli savings vehicle under US law varies. Keren Hishtalmut is particularly interesting because it's a relatively short-term account that can be withdrawn after six years — the IRS may treat it as an ordinary savings account rather than a pension, making contributions currently taxable as wages and earnings annually taxable as investment income. Israeli pension kupot may receive more favorable treaty treatment as retirement accounts, deferring US tax until distribution. Both types of accounts must be reported on FBAR and potentially Form 8938, and their classification as pension or savings accounts affects whether Form 3520 (foreign trust) reporting applies.
