Can you guide me on transferring my US retirement accounts to Israel? 


Yes, but we generally do not recommend doing so. You cannot transfer a US retirement account to an Israeli retirement account. Each is a separate entity to which you may contribute and then take (primarily taxable) distributions. There may also be penalties if you take money out of US retirement accounts before age 59.5. Therefore, we believe it makes sense to keep your US retirement assets in consolidated US Individual Retirement Accounts until retirement age (and often thereafter too).
