I provided my information (including SSN) on W-9 to a parent so he could claim childcare expenses on his tax return. Accidentally I found that he claimed more than he paid me for child care services. I requested him to file an amended tax return and correct the wrong amount, but he refused. What should I do in order to protect my SSN from parents who report wrong amounts by using my SSN? I do have contract with a parent, which included the child car service fee agreement.
Thanks,
