What source of gain does Jim need to report as taxable by California after selling Texas property?

In California, the tax implications for real estate transactions primarily revolve around the residency status of the property owner and the source of the income. In this scenario, Jim is required to report any taxable gains derived from the sale of property.

Since Jim sold property located in Texas, he must report the gain based on California's tax laws. California taxes residents on their worldwide income, which includes capital gains from property sold outside the state. Therefore, if Jim has a gain from the sale of the Texas property, he is obligated to report that gain on his California tax return.

Specifically, if the question indicates that Jim has a $15,000 gain from California-related income, this amount is considered taxable under California tax law. This is because, despite the property being located in Texas, any gains realized can be reported as part of the California income as long as there is a link to Jim’s income as a resident of California.

Overall, Jim should report the gain that is attributable to his overall income declaration in California, as the state does not exempt non-resident gains for tax purposes. Thus, he would report the $15,000 gain originating from California income sources.
