The Rule of 55 can let some workers access a 401(k) before age 59.5 without the standard early-withdrawal penalty.

What It Is

If you leave your employer in or after the year you turn 55, you may be able to withdraw from that employer's 401(k) without the 10% penalty. Ordinary income tax still applies.

Common Mistakes

  • Rolling the plan into an IRA too early
  • Assuming all plans permit identical withdrawal options
  • Ignoring tax bracket impact on large distributions

Planning Workflow

  1. Estimate bridge spending to age 59.5
  2. Model drawdown with Retirement Number Calculator
  3. Compare with delayed-claim options in Social Security timing guide
