Have a Tax Question? Ask a Tax Expert
It is unclear which of you has the tax debt, you or your son. You mention your son and the 401k withdrawal so if he had a tax debt because of that and that is the issue let me know.
You mentioned your own problems and a sale. If the IRS believes you owe because of a cancellation of debt on the sale of your home then let me know.
It could be either based on the post you made but it is unclear so I need to know which of you (you or your son) is being asked to pay.
