If you turn 55 this year and leave, you can pull from your current 401k without the 10% penalty. The 1099-R should show a "2" in Box#7 that indicates > "Employee/Taxpayer has not reached age 59.5 and it's KNOWN that the distribution is a Roth IRA conversion, OR a distribution from a qualified retirement plan (401k) after separation of service, in or after the taxpayer has reached age 55"
The 401k exception only applies to the 401k of the company you actually separated from at 55+, (code "2" on 1099) If you have another 401k from a different company the 10% penalty still applies to any money withdrawn from that account before 59.5. (code "1" in Box#7 on 1099-R)
Also remember if you have any shares in the "VZ-Stock fund", you can always opt to take the VZ DIV (as opposed to reinvestment) at any age, working or not. (Code "U" in Box#7 on 1099-R) I did that a few times in my 30's just to help get myself debt free.
Also note if you are planning to dip into the 401k after separation between the ages of 55 and 59.5, you are going to have to actually LEAVE IT in the Verizon 401k plan. IF you roll the money to an IRA, the exception rules no longer apply. Withdraws MUST come from the 401k account associated with the Employer you separated from at 55 to qualify. Its a trade off... but on the bright side, while you wait to turn 59.5 the VZ 401k Fidelity account fees are pretty low. Likely a lot lower than the fees charged by the financial advisers who are dying to get their hands on your retirement account.
If you are retirement lump sum eligible, but under 59.5, you can opt to roll the Lump Sum into your 401k to gain access to it between 55-59.5. Then at 59.5 you can always roll the whole account over to whatever IRA you want. And if you don't actually need any money before your 59.5, you can roll the whole thing to any financial adviser you want right off the bat. Just remember if something pops up between now and 59.5, you will have to pay the 10% penalty. Just some more food for thought.
