Daniel D. Tompkins was the only vice president to work for free. His entire salary was garnished for outstanding debts to the state of New York. Of course, his personal finance issues along with a raging case of alcoholism meant that Tompkins rarely had the time, or ability, to perform his vice presidential duties.
