How can I e-file my Ohio tax

In order to e-file your State tax return you have to have already e-filed your Federal tax return and have it accepted before it will allow you to e-file your State return. Also, it may be due to some State forms are not yet available, so you would have to wait until they are ready. Please see the state forms availability table below to see if all your State tax forms are ready:
