Arizona Republic:  “This month, as the tax year nears an end, thousands of Arizonans are expected to donate money to private-school tuition groups and claim a tax credit  that reduces what they owe the state.   Many taxpayers will recommend that their money go to specific students as scholarships; many tuition groups will honor those wishes.   But these taxpayers, and the school tuition organizations that give out the scholarships, may be running afoul of federal tax law.”
