It is easy to use, it's user friendly interface makes tax calculations simple for our office staff as well! There are some functions that I don't like about this software such as not being able tot print out reports or having other features available in MS Excel/Word but overall we love using cch sales taxes because of its ease-of -use & accuracy when doing payrolls etc., nothing really dislike so far!! Great product if you need an accurate way calculate your state income / FICA deductions (for employees).
