My step daughters Dad sends her money by depositing it in her checking account, He has his own business and sent her a 1099, She does not work for his company, and I always figured it was a form of support or an allowance, but he is trying to use her for a tax write off. What can she do other than pay the tax? My step son has the same thing, but he didn't get sent a 1099 and is on better terms with him than my step daughter... should he be reported to the IRS?
