You should only enter the beginning and ending inventory for a balance sheet if they're different from the beginning and ending inventory entries for the cost of goods sold. Select your module below for instructions.
The Cost of Goods Sold (COGS) shows up on Form 1120, line 2 as a negative amount and is added to the income instead of subtracted from it. Here's why:
If you look at the Form 1125-A for the COGS calculation, you'll see that line 7, Inventory at end of year, is greater than line 6, Total. When you add lines 1 through 5, the result is a negative amount on line 8, which is then transferred to Form 1120, line 2.
On Form 1120, line 2 is subtracted from Line 1e. Since line 2 is negative and being subtracted, it's added to Line 1e and a gain is recognized for the difference between the costs incurred and the value of the inventory.
Form 8916-A, Supplemental Attachment to Schedule M-3, is required when cost of goods sold, interest income or interest expense is included on the return. You have to enter it manually. Refer to this article for information on generating Form 8916-A in the program.
