Can I start a 503b Tax deferred account while working part-time and already collecting Social Sec. benefits?

Uhhh... Section 503(b) applies to bankruptcies. There's no such thing as a "503(b) tax deferred account."





And section 403(b) applies to certain educational organizations and non-profits so that wouldn't apply to you either.





You could set up a traditional IRA if you are under age 70.5, but that's probaby about it.
