MADISON, Wis. — Gov. Scott Walker wants back-to-school purchases to be free from sales tax the first weekend in August.

Walker unveiled the proposal Wednesday at a news conference at Shopko’s headquarters in Green Bay.

Walker plans to call for the sales tax holiday weekend in the state budget he delivers to the Legislature early next year. Under his plan, the sales tax would be waived on school supplies, computers costing less than $750 and clothing items costing less than $75 each.

The tax holiday would be the first weekend in August next year and again in 2018. After that, the Legislature would have to vote to continue it.

Assembly Republicans on Wednesday also said passing a sales tax holiday next year is one of their priorities.
