Which statement about state taxation on interstate commerce is correct?

• A. Tax must be substantially connected to the state and proportional to in-state activity
• B. Tax may burden interstate commerce regardless of nexus
• C. Tax may only be based on the amount of in-state goods sold
• D. Tax may burden interstate commerce if Congress authorizes

Answer: (A)

The main idea is that state taxes on interstate commerce must be tied to the taxpayer’s activities in the state and must be fairly apportioned so only the in-state portion is taxed. This means there must be substantial nexus (a real connection to the state) and the tax must be allocated in proportion to that in-state activity. Substantial nexus ensures the state can justify taxing the business; it isn’t enough for the company to have nationwide operations with no real link to the state. Once nexus exists, the tax must be fairly apportioned—the in-state share of the activity is what gets taxed, often using a formula that reflects property, payroll, and/or receipts attributable to the state. That’s why this statement is correct: the tax must be substantially connected to the state and proportional to in-state activity. The other options fail because they either ignore the nexus requirement (taxing without connection), are too narrow in scope (based only on in-state goods), or rely on Congressional authorization in a way that doesn’t replace the need for proper nexus and apportioned taxation.
