Nonresident taxpayer

For purposes of allocation and apportionment of income under this chapter, a taxpayer is taxable in another state if: 1. In that state the taxpayer is subject to a net income tax, a franchise tax measured by net income, a franchise tax for the privilege of doing business, or a corporate stock tax; or 2. That state has jurisdiction to subject the taxpayer to a net income tax regardless of whether, in fact, the state does or does not.
