Can you close your 457 deferred compensation plan?

You should be able to do this but you may want to look at the plans rules and documents to determine your best method to do this for your benefit.

You definitely can close your account but you really can't withdraw your funds before you separate from service (unless you have an unforeseeable emergency). Once you separate, you can close out your account by withdrawing it all or transferring it to another employer's 457 plan or to an IRA. Watch out though when transferring to an IRA...you can take the money penalty-free from a 457 plan at any age after you leave your job, but have to be 59 1/2 or over to avoid a 10% penalty when pulling money from an IRA (with some exceptions).
