Common mistakes
- Using the wrong section: Section A is for California residents only. Nonresidents and part-year residents must go to Section B.
- Starting estates and trusts on line 1: In Section A, estates and trusts begin on line 3.
- Continuing when told to stop: If Section A, line 3a is positive, enter 0 there and on line 25. Do not complete the rest of Section A. Complete Parts II and III if you have a prior-year carryover.
- Entering negative amounts where positive amounts are required: Part I directs you to enter lines 4 through 24 as positive numbers. Part II gives the same direction for lines 2 through 5.
- Overlooking the instructions: Part II specifically reminds you to read its instructions. Those instructions were not included in the supplied text.
