STOP!!! Don't take Social Security early! With that kind of cash gift you don't have to take SS. And you will be giving up a huge increase in monthly benefits that you would get if you waited till your full retirement age of roughly 67 -- or even till the maximum age of 70! You can use the money from the "gift" in place of taking Social Security. You'll get a much larger monthly check for life if you want to start your benefits.As for taxes, you will owe no taxes on the "gift". The giver might want to file a gift tax return for his/her own estate tax purposes, but that is not your issue. The amount of assets you have does not impact your Social Security check.
