Questions related to the acquisition or transfer of California real property in Form 100 are significant because they affect the taxpayer's California taxable income. The taxpayer is required to report the sale or exchange of California real property in the year of the sale or exchange, and may be subject to California income tax on the gain from the sale. The taxpayer may also be required to file a California Real Property Tax Return (Form 571) if they are a nonresident or part-year resident and own California real property. The taxpayer should carefully review the instructions for Form 100 and complete the applicable sections related to real property transactions.
