"Nothing is certain but death and taxes".

Since Israel applies no estate tax, Israeli tax legislation grants neither a tax credit nor a ‘step up’ with respect to estate tax paid in a jurisdiction outside of Israel. Thus, when the deceased was an Israeli tax resident who owned foreign assets subject to estate tax outside of Israel, although the foreign country may grant a ‘step-up’ in order to prevent a double taxation in the local country, this will not prevent double taxation in Israel.
