Anyone works for a tax place?

Hi mamas,

Hopefully someone can give me some info.

So my son’s dad is asking me for MY social security number, he said he is doing his taxes and he needs it so he won’t have to pay.

So basically we never married we briefly lived together and we split 4 years ago our son is 5

We have a mutual verbal agreement on the amount of money he gives me for child support which is $250, he said that the person that is doing his taxes needs my ss because since we don’t have a court order for the child support it will go under alimony.

I told him I’m not giving him my ss now he’s saying he will get me in trouble with the irs?

Help please
