What California Form 3544 Is For
California Form 3544 explains the assignment of credits between corporations filing a combined California return. It supports the assignment of credits between an assignor and an assignee under Revenue and Taxation Code section 23663, subject to regulations, definitions, and limitations administered by the California Franchise Tax Board.
When You’d Use California Form 3544
A taxpayer uses Form FTB 3544 when a corporation assigns eligible credit amounts to an eligible assignee within aggregated eligible assignees during the same tax year. The form must be attached to Form 100 or Form 100W with the original California Corporation Franchise or Income Tax Return, not amended tax returns.
Key Rules or Details for 2013
- Eligible credit rules: Assignment of credits applies only to tax credits authorized under the Revenue and Taxation Code and California Code of Regulations, excluding credits restricted by statute or federal provisions.
- Eligible assignee definition: An eligible assignee must be part of the same combined reporting group and subject to identical credit rules, taxable income calculations, and net income limitations.
- Assignment limitations: The assigned credit amount remains subject to IRC Section 382, IRC Section 383, and Regulations 23663-1 through 23663-5 without expansion or reduction.
- Carryover treatment: Credit carryover periods continue unchanged after assignment, and unused amounts follow the same rule, extent, and provision applicable to the assignor.
- Joint responsibility: Both the assignor and assignee remain responsible for corrected credit adjustments, proposed assessment amounts, and credit recapture under applicable regulations.

Enter corporation details, taxable income data, assigned credit amount, and applicable notes for each credit type, including California Motion Picture and Television Production Credits or Low-Income Housing Credit.
Step 4: Attach to the state return
Attach Form 3544 to the CA state return using Form 100 or Form 100W and ensure Schedule Z reflects the assignment of credits accurately.

Common Mistakes and How to Avoid Them
- Late assignment filing: Assignments attached to amended tax returns are invalid, but this can be avoided by filing Form 3544 with the original tax return for the applicable tax year.
- Incorrect assignee designation: Listing entities outside the combined group causes disallowance, but this can be avoided by verifying aggregated eligible assignees before submission.
- Overstated credit amounts: Assigning amounts exceeding available credit creates assessment exposure; however, this procedure can be avoided by reconciling the balances of Schedule D, Schedule D-1, and Schedule R.
- Missing limitation disclosures: Omitting IRC Section 382 or IRC Section 383 limitations increases audit risk, but this can be avoided by attaching clear limitation statements.
- Improper credit type selection: Assigning an ineligible or identical credit type incorrectly can result in rejection; however, such an error can be avoided by reviewing relevant regulations and guidance on California Enterprise Zones.

What Happens After You File
Once filed, the assignment of credits becomes irrevocable and binding on both entities. The assignee applies the credit against corporate income or income tax liability, subject to carryover rules, credit recapture provisions, and ongoing compliance with California returns section requirements.
