what are the biggest sources of state funding for schools in most cases
Report Abuse. Some states would be D (those not having income taxes) and others would be C (those states not having property tax). Most funding for schools systems do not come from the state but through the local government (city/county) who gets most of their revenues from property taxes.est Answer: State funding for schools comes from sales taxes and income taxes. Local funding for schools comes from property taxes. I think your best answer is C. sales and income taxes.
