The taxman is relentless. He only visits when you decide to go backwards so be warned. Sometimes he knocks on the front door. Less often he will knock on the back door. Sometimes he will burrow underneath your house to come from below. Many times the taxman is the invisible one. Don't try to pay the taxman a variable rate - he is a creature whose diet consists of only constants.
