Common mistakes
- Not rounding amounts: The form says to round amounts to the nearest dollar.
- Continuing when line 11 is zero or less: Stop there. The form says you do not qualify for the manufacturing credit.
- Missing the all-Wisconsin shortcut: If all manufacturing activity occurred in Wisconsin on property assessed as manufacturing, check line 12a, skip lines 12b and 13, and enter 100.0000 on line 14.
- Including pass-through income on line 15f: The form says not to include partnership or tax-option (S) corporation income there and directs you to line 17.
- Leaving out Schedule CF: Include it for a carryover on line 19 or if the credit is not used in full on line 22.
Questions people ask
What percentage is used to calculate the credit?
Line 16 uses 7.5%. C corporations multiply line 15d by that rate; partnerships and tax-option (S) corporations use line 15e; individuals and fiduciaries use line 15g.
Where do I report a credit passed through from another entity?
Report it on line 17, with the entity name and FEIN. The form directs you to the instructions for limitations, but those instructions were not supplied.
Where do I report unused manufacturing credit from earlier years?
Enter the carryover on line 19 and include Schedule CF.
Is there a business income limitation for individuals and fiduciaries?
Yes. Part II is labeled for individuals and fiduciaries only. On line 22, individuals and fiduciaries enter the smaller of line 20 or line 21, which is the tax on qualified business operations.
