Common mistakes
- Do not include the web fill-in instruction page with the return.
- Do not handwrite information or use commas in amounts. Use a minus sign, not brackets, for negative numbers.
- Use the form’s print icon to ensure all required fields are completed. Do not print on both sides. Set page scaling to “none” and uncheck Auto-Rotate and Center.
- Do not mix form types or submit photocopies. Submit original returns only.
- Calculate apportionment factors to four decimal places.
- If Form NC-PE is required, attach both pages. The Department warns that it may be unable to process the return without them.
- Provide every partner with an NC K-1 for Form D-403 and any other information needed to prepare the appropriate North Carolina tax return.
- Enter tax credits on Part 4, Line 8, only if the partner can claim them. Use Line 23 only for credits the Taxed Partnership can claim.
