When you leave a job — whether you're changing employers or retiring — your old 401(k), 403(b), or 457(b) sits there waiting for a decision. The HR department sends paperwork. A new employer's plan invites a rollover. An advisor or insurance agent suggests "consolidating." The IRS sends a Form 1099 if anything is distributed.
The pressure to "do something" is real. So is the cost of getting it wrong.
A few things make this decision uniquely consequential:
- Cash distributions trigger immediate tax — and possibly a 10% early-withdrawal penalty. Once distributed, money pulled out of a retirement account cannot be put back in (with very narrow exceptions).
- Indirect rollovers can fail in ways that look like cash distributions. The IRS does not forgive missed deadlines.
- Annuity contracts purchased with rolled-over IRA money have surrender charges that can lock dollars up for 5-10 years. Reversing the decision can cost real money.
- Some 401(k)-specific tax strategies are lost forever once you roll the money to an IRA. Net Unrealized Appreciation (NUA) on employer stock is the most important of these.
- ERISA creditor protection on 401(k) money is strong and uniform. IRA creditor protection varies by state and is generally weaker — particularly in California, where the protection is limited to amounts "reasonably necessary" for support.
These are not reasons to never move 401(k) money — they are reasons to make the decision deliberately, with the right professionals, and with a clear-eyed understanding of what you're trading for what.
