I file Sales tax for 23 States . I’m currently in the process of using Fasttax (Fasttax.com) I’ve created a dataport to export my Sales by State, County & city. I’m currently dumping the info into excel & manually filing the returns. Fasttax will eventually take the info & prepare my reports for me. I hope to have Fasttax intergrated in about a month. I’ll keep you updated of my “success”
