Education expenses for grades K-12 are not deductible on your Federal return, whether for private, public, or home schooling, nor are the expenses for tutoring, after school lessons or after school activities, such as dance lessons, sports, etc. Some states allow deductions/credits for K-12 education and/or home schooling expenses; if your state has these deductions available, you will be prompted to enter them when you prepare your state return. (As far as I know, the states that offer any sort of K-12 deductions/credits are Illinois, Indiana, Iowa,Louisiana, Minnesota, and Wisconsin)
I dont fully agree with the above statement. My children went to private school(K-9) for many years. The school always gave us statement end of the ear for tax filling. In the state of VA for sure yes there is tax credit.
about Kumon I dont know.
