Questions people ask

How does Schedule A calculate the credit amount?

Divide the total property cost in column B by the number of pumps or recharging stations in column C, then multiply by 50%. Enter the lesser of that result or $5,000 in column E. Multiply column E by the number in column C to get column F. The form refers filers to instructions for property and cost details.

Where do I report credit allocated by a partnership?

Enter the partnership’s name, EIN, and allocated credit in Schedule E. Enter the total on line 18 and carry it to line 3.

How much credit can I use this year?

For filers completing Schedule C, line 13 is the lesser of the available credit on line 7 or the credit limitation on line 12. Enter that amount on your franchise tax return as well. New York S corporations do not complete Schedule C.

Where is unused credit shown?

Schedule C, line 14, shows the credit to carry forward: line 7 minus line 13. New York S corporations do not complete this schedule.

Where do I report recaptured credit?

Use Schedule D. Add the recaptured credit on line 15 and your partnership share of recapture on line 16. Enter the total on line 17 and carry it to line 6. The form refers filers to instructions for recapture details.
