If my bro pay my $120k mortg & 40K student loan will he stil hav to pay a gift tax by payin the lenders direct
Sort of. these are gifts subject to gift tax and have to be reported on form 709. If your brother has made no other gifts in his lifetime, he won’t actually have to pay any tax.
It makes no difference whether he writes the check to you or to the bank. The only exception would have been if he’d paid your tuition directly to the school at the time you were enrolled.
