Virginia Code Title 58.1. Taxation § 58.1-332.2. Definition of income tax

A. For purposes of the credits in §§ 58.1-332 and 58.1-332.1, the term “income tax” is a term of art that refers to a specific type of tax levied on earned and unearned income and shall not include any other type of tax merely because it may be measured by or referenced to gross or net income. An income tax includes, but is not limited to, a tax imposed on all income of an individual if a resident, or all income of an individual from the jurisdiction's sources if a nonresident; however, an income tax so imposed may incorporate other provisions that grant exemptions, exclusions, deductions, subtractions, credits, or other preferences for specific types of income, expenses, individuals, or other criteria.

B. An income tax shall not include:

C. The credits in §§ 58.1-332 and 58.1-332.1 shall apply only when the tax imposed in the other state or foreign country is substantially similar to the tax imposed by Article 2 (§ 58.1-320 et seq.), as defined by this section. The nomenclature used to describe the tax of the other jurisdiction shall not be binding on Virginia for this purpose whether such nomenclature is that of the other jurisdiction's legislature or courts or the United States Congress or courts.
