Questions people ask
How do I calculate the total available credit?
Add the qualifying current-year tax on line 1a, partnership credits on line 1b, and unused credit from the preceding period on line 2. Enter the total on line 3.
Where do I report credits allocated from partnerships?
List each partnership’s name, EIN, and allocated credit amount in Schedule D. Enter the total on line 16 and on line 1b.
What if I need more room to list properties?
Submit additional forms. Schedule A includes a place to enter the total from those additional forms.
Where does the form calculate unused credit?
Line 10 subtracts the credit used on line 9 from the total available credit on line 3. For Article 9-A taxpayers completing Schedule C, line 15 subtracts the refund and overpayment credit amounts on lines 13 and 14 from line 10.
Who can use the refund or overpayment credit section?
Schedule C is labeled for Article 9-A taxpayers only. It includes lines for the amount eligible for refund or credit, the amount to be refunded, and the amount to be credited as an overpayment. The form refers filers to the instructions for these calculations.
