The life expectancy is to low ( approx 3%) and I am not sure if I can do the monthly withdrawl and not get hit with the 10% penalty. Not really sure of the IRS 52T lasw. Also I have to be aware that my TSP money need to last at least 30 years.
I am also a LEO, so I have looked into our situation quite a bit. We are under the same rules in this case as ATCs and Firefighters.
Rolling over will not solve the problem of the 10% penalty. If you retire before the year in which you turn 55, you will not be able to avoid the penalty if you touch it before 59.5., unless you use the life expectancy scenario, buy an annuity (bad move) or go with the 72t (which will be the same roughly as the TSP life expectancy as it is calculated approximately the same way)
And if you decide on taking the payments based on life expectancy, you can change to any other method of withdrawal at 59.5.
Will you really need to access your TSP at 52 though?
In that you get your basic benefit and SS security supplement, you might already have what you need, along with a part time job. Also, many are not aware that the SS supplement is not affected by other earnings until you turn 55, at which time is will be reduced just as Social Security is affected by personal earning.
Finally, if you do need to draw on our TSP account to live when you retire at 52, then you might really look at your situation and see if you are really at the point that you can retire at 52. You want to consider putting ofj your retirement a couple more years, and go out at 55. Also, you only have to work until the first week of January in the year in which you turn 55 to retire without the penalties. Depending on when your EOD is, this could be as little as 24 months.
Also, for every year after 20, you will get an additional 1% per year added to your basic benefit. If you work until 55, this could put you at around 42% of you hi-3, plus your hi-3 is higher due to the extra time in service.
Unless you have a dynamite job waiting for you outside of fed service, it might be strongly to your advantage to put up with your job for just a bit longer for substantial gains and flexibility.
Best of luck!
