I understand the intent and your position on it. My only point is: a parent is legally required to provide the necessities of life for their child. Granted, whether dad calls it rent or a fine for being stupid and getting caught committing a crime is merely semantics but I think dad would be questioned less if he called it a fine. If not, next thing you know dad is going to be charging OP for meals
.
I'm curious how the money is being taken out of the check. I would think dad is the payee as the guardian of his minor son but OP makes it sound so official.
The other thing dad needs to be careful with: if he charges rent, it is income to him. OP could be a jerk about it and make a call to the IRS about it. I would love to see the ensuing conversation between dad and the IRS:
IRS; well mr OPdad, I see you collected $3240 in rent last year but you have not included that as income on your 1040. Care to explain?
mr. OPdad: it wasn't really rent. I was trying to teach my son a little responsibility. In fact, I actually put the money in a separate account and intended on giving it to OPson when he is off probation and moves out. It was simply a means to force him to save some money.
IRS: well, that's all good and well and we understand and even respect your intent but the fact is; you did consider it rent which is taxable income. So, now you owe us $642 in taxes plus $1000 penalty fee. You good with that?
