You left in the year you turned 55, at or past 55, so withdrawals from this plan owe no 10% additional tax. On $40,000 that saves $4,000. After income tax you keep $35,370.

Federal income tax it adds-$4,630

The plan withholds $8,000 for federal tax when it pays you directly. That is a payment toward the tax above, settled on your return.

What the rule of 55 covers

Withdrawals from a workplace plan before 59½ normally owe a 10% additional tax on top of income tax. Section 72(t)(2)(A)(v) exempts them when you leave the employer in or after the calendar year you turn 55. Income tax still applies.

  • The 401(k), 403(b) or Thrift Savings Plan of the employer you left in or after the year you turned 55.
  • Leaving for any reason counts: retiring, quitting, a layoff or being fired.
  • Public safety employees of a state or local government, such as police, firefighters and EMS, qualify from the year they turn 50, or after 25 years of service under the plan.

What it does not cover

  • IRAs, including a rollover IRA holding money from that plan. Roll it over and the exception is gone.
  • A 401(k) from an earlier employer you left before the year you turned 55.
  • Leaving at 54 and waiting until 55 to withdraw. The age that counts is the year you leave.

Check your plan before you count on it. Some plans only pay out the whole balance at once, which can push a large amount into one tax year. Taking part of it, or leaving it in the plan and drawing it down over several years, is up to the plan’s own rules.

Rule of 55 vs 72(t)

Both avoid the 10% additional tax before 59½. The rule of 55 is the simpler one when it applies. A 72(t) series works from an IRA at any age but locks you into equal payments.

Method and sources

The age test uses calendar years: the rule counts the year you turn 55 (50 for public safety employees), whatever the month you leave. Federal and state tax are the withdrawal calculator’s: the return computed with and without the withdrawal on top of your other income, with the 2026 tables. Anyone 61 or older at the end of 2026 is past 59½ for the whole year.
