Don't forget about taxes. Although each NHL season is composed of months two separate calendar years, having a salary in the United States of $875,000 we can estimate that he would have to hand over $281,534 in federal income taxes. For comparison, that is about the same amount of tax as the tax paid by 35 median high school teachers, 39 median police officers, or 56 median fire fighters. After paying the federal government, he would have $593,466 left over. However, he may still need to use some of that money to pay state or city taxes as well.
