Congress possesses the power to levy and collect various taxes in order to finance government operations. All federal taxes must have the same rate nationwide.

This is the Commerce Clause which empowers Congress to regulate foreign and interstate trade, as well as trade with Indian tribes.
Congress may set the rules for how aliens can become citizens of the United States. Congress can pass laws relating to bankruptcy.

The Declaration of Paris of 1856 forbade them and we have kept with this ban since the Civil War, thus negating the power of Congress to issue them.
Congress may form and fund armies, but money cannot be appropriated for these armies for more than a two year period.
