The Federal Income Tax After Non-Refundable Credits would be located on the IRS 1040. It is on line 22 of the Federal Income 1040 return, not the IA 1040. The calculation is done by subtracting line 21 (total of nonrefundable credits) from line 18, total tax.
How do you calculate/divide it between husband and wife based on income ratio? I had my taxes professionally done last year and attempting Turbo this year. Thanks!
If you filed a joint federal return last year, the easiest way would be to apply the percentage of each's income to total income and apply that percentage to the amount that shows on Line 22 of your 1040. As it apparently applies to only Federal Income Tax, the amount on line 23 should not be included.
