Rule of 55 Early Retirement
Rule of 55: 401k withdrawal penalty-free if you separate from service at 55+. Only that employer's 401k. Federal income tax still applies.

The Rule of 55 lets you withdraw from your 401(k) without the 10% early withdrawal penalty if you separate from service in the year you turn 55 or later. Only applies to the 401(k) from the employer you're leaving — not IRAs or other 401(k)s.
Eligibility Requirements
You must separate from service in or after the year you turn 55. Public safety workers (police, firefighters): 50+. Only applies to the employer-sponsored 401(k) from which you separated. Cannot apply to IRAs (10% penalty until 59.5).
Strategic Timing
If retiring before 55: roll over old 401(k)s to current employer plan BEFORE separating, IF current plan accepts rollovers. Then apply Rule of 55 to combined balance. Maximizes penalty-free withdrawal potential. Don't roll to IRA prematurely — loses Rule of 55.
Tax vs Penalty
Rule of 55 eliminates the 10% PENALTY. Income tax (24-37% federal + state) still applies to withdrawals. Plan tax brackets — taking large amounts could push you to 32-37% bracket. Combine with Roth conversions in low-income retirement years.
