“The Senate bill also raises the child tax credit from $1,000 per child to $1,650.”
I think this is wrong. It is my understanding that the child tax credit goes to $2000.00 under the Senate Bill. I think the $300.00 per adult dependent, filer and spouse is retained from the House bill (family tax credit). Trying to find text of Senate bill to verify.
This article says the credit for non-child dependents is $500.00 in the Senate bill.
