Common mistakes
- Leaving consolidated-return information incomplete. Schedule B requires all corporations with Alaska nexus included in the return, other than the taxpayer listed on page 1. The form warns that failure to complete this properly may result in penalties.
- Missing Form 6220. Attach it if Schedule A, line 9 is more than $500.
- Continuing past the stop instruction. If Schedule A, line 15 is greater than zero, the form says to stop.
- Using the wrong sign for an overpayment credit. Enter the amount credited to 2026 estimated tax on Schedule A, line 16 as a positive number.
- Overlooking Schedule I–1 skip instructions. Oil and gas transportation companies only must skip lines 5–8 and go to line 9. Oil and gas producing companies only must skip lines 9–12 and go to line 13.
