An individual can purchase no more than $10,000 of Series EE bonds and an additional $10,000 of Series I Savings bonds in one year. Since a Revocable Living Trust uses your social security number, that is the limit that can be purchased under any one SS number in a year.If you've created a RLT and want to rename the bonds in the name of the trust you can do that, without limitation. The limits apply only to the annual PURCHASE of bonds.

They have re-worked the adjustments on them to make them a rather unattractive investment -- even compared to money market funds!
