Questions people ask
Must I file if only another member of my combined group has a PNOLC balance?
Yes. The form must be filed for each tax period when you or any member of the combined group claims a PNOLC subtraction or carries a balance.
How do I calculate the PNOLC subtraction available for the tax period?
On Schedule C, add line 1, the tax period allotment, to line 2, the unused subtraction carried forward from the prior tax period. Enter the total on line 3.
What if apportioned business income after addback is zero or less?
Schedule B, line 1, directs you to enter 0 on line 5, the maximum PNOLC subtraction for the current tax period.
How should I round the tax calculation on Schedule B, line 2?
Multiply line 1 by the appropriate current-period business income base tax rate from Form CT-3-I or CT-3-A-I. Round the result up to the next highest whole dollar.
