<prompt> Human: So my son mows a few of the neighbors laws for some extra money. He started a little over a year ago, and has about 5 houses he does every week for around 25 a cut.One of the houses is a rental property and the owner asked for an invoice to claim on his taxes. Could this have any negative implications for my son, who hasnt been claiming the income?  <response>: The landlord wants an invoice so he can expense the lawncare against the income of the property most likely so he has a record of it and wont forget how much he paid. He cant send a 1099 misc without your sons SSN. Remember tax stuff is all tracked by SSN. Honestly Im sure a 5 minute phone call with your family accountant should clear this matter up. If hes making enough to pay taxes you can start teaching him to make quarterly estimated payments and itll be a really educational experience.
