Pay taxes first so i dont go to prison. Parcel out tithe to various Church concerns including but not limited to my home church congregation, then pay my depts, my parents depts, help my sister with hers, put money in interest bearing acct to help my nieces and nephews with college, put a large chunk in savings and invest the rest wisely. Id go part time at work or open my own business maybe. Eventually build a small house.
I would give almost half of it to the US TREASURY , and not because I want to. They insist on it. If I already had that much AFTER taxes I would invest it in a diversified manner to provide for my family now and in the future.
