Who is eligible to participate in HCPSS' 403(b) and 457(b) plans? What is the minimum contribution for 403(b) and 457(b) plans? How often can I change my contribution amount to my 403(b) and/or 457(b)? Is there a limited time of the year where I can change my contribution amount to my 403(b) and/or 457(b)? What are the costs to participate in a 403(b) and/or 457(b)? May I roll over or transfer money from one retirement plan to another? May I withdraw money from my 403(b) and/or 457(b) account while I’m still employed? When may I start to take withdrawals from my 403(b) and/or 457(b) account without a penalty? May I change my withdrawal option, amount, or frequency once I start my payout from my 403(b) and/or 457(b)? Are there loan and hardship provisions for 403(b) and 457(b) accounts?
