While the Social Security deferral was nice while it lasted, junior soldiers will now feel the pain of repayment.

Let’s say you are a Private First Class in your early 20s, with multiple children, and have been in the military for just two years. The Basic Pay for a PFC with two years is only a mere $1,900 a month.

For that soldier to not having to pay his social security for three months was great, especially during this time of the year.

Now, starting in January, soldiers will go back to paying their six percent in Social Security and another six percent for three months to pay back the deferral.

That could be hundreds of dollars of their pay in December. And for the PFC above with multiple children, this could be devastating.
