I'm not going to let my dad claim my son on his taxes
Why is your dad claiming your son on his taxes?
To get a tax break. I am the one taking care of my son now and I deserve the tax break more.
If you're in charge of your son, that makes sense. It is better to do the legal things when it comes to taxes and tax credits.
Dad is just a useless idiot.
You have every right to claim your son and your dad needs to mind his own business. Tell your dad that he needs to find other ways to receive his tax breaks and to leave your son out of it.
