  • Leaving Part A incomplete: Part A must be completed in full for the election to be valid. Part B must also be completed in full when credit is received or claimed.
  • Treating the assignment as reversible: The election to assign credit is irrevocable.
  • Completing both parts: The form directs you to complete either Part A or Part B.
  • Combining multiple assignors, assignees, or credits on one form: Follow the separate-form requirement for each assignor per credit or each assignee per credit.
  • Missing the limitation checkbox: Check Part A, column (e), if the assigned credit is subject to limitations.
  • Including credits elected to be refundable in carryover: If you answered “Yes” to the Form FTB 3870 election question, do not include those credits in Part B, column (k).
  • Exceeding the credit limitation: If the taxpayer is subject to the limitation, total credits in Part B, column (j), cannot exceed $5,000,000. For taxpayers in a combined report, the limit applies at the group level.
