Report, if you have a problem with this page“ When your child is a little older, you can teach him about our tax system in a way that is easy to grasp. Offer him, say, $10 to mow the lawn. When he has mowed it and asks to be paid, withhold $5 and explain that this is income tax. Give $1 to his younger brother, and tell him that this is "fair". Also, explain that you need the other $4 yourself to cover the administrative costs of dividing the money. When he cries, tell him he is being "selfish" and "greedy". Later in life he will thank you. ”
