Who told you that? That information is incorrect and silly. Someone gave you poor advice. Think of roommates who live together----do you think they have problems when they file tax returns for themselves using the same mailing address? Or married couples who file married filing separately? They can use the same mailing address. It is very common for people living at the same mailing address to file their own tax returns -- for all kinds of reasons. Parents and dependent children can file their own returns ---- from the same mailing address. parents and their children who are no longer dependents---but still living at the same address--can also file their own tax returns. That does not result in being "flagged" or getting any sort of penalties.
