Florida’s back-to-school sales tax holiday starts today and runs through Sunday and will allow shoppers to avoid paying state and local sales taxes on most clothes and footwear costing $60 or less and school supplies that cost $15 or less. However, for the second time in six years electronics are excluded. The state has offered the school tax holiday 16 times since 1998. The holiday is projected to save shoppers 32.7 million dollars, reducing state revenue by 26 million dollars and local-government revenue by 6.7 million dollars.
