Long story short, They found out they couldn’t amend tax law with this bill so they threw in a $4000 SSN Tax credit to make up for the tax that would have been paid.
But a deduction and not a credit, so why not at least make it a credit and not a deduction
But the $4000 not a tax credit. It’s a tax deduction. With a tax credit, you deduct the amount directly from the taxes you owe. But with a tax deduction, you deduct the amount from your taxable income.
Big difference.
