Catherine McCollough V. Maryland (1918)

The state of Maryland imposed a tax on the bank of $15,000/year, which cashier James McCulloch of the Baltimore branch refused to pay. The case went to the Supreme Court. Maryland argued that as a sovereign state, it had the power to tax any business within its borders. McCulloch’s attorneys argued that a national bank was “necessary and proper” for Congress to establish in order to carry out its enumerated powers.
