What amount of Seaman Abbott's income from Hardware Store Inc. is subject to California tax?

To determine the amount of Seaman Abbott's income from Hardware Store Inc. that is subject to California tax, it is important to consider the specifics of California tax law surrounding income. California generally taxes individuals on their income derived from all sources, including wages, salaries, and business income, within the state.

If the context surrounding this question indicates that Seaman Abbott only earned $9,000 from Hardware Store Inc. and this amount represents the total income subject to California tax, it would be appropriate to conclude that this is the taxable income.
