The state of Texas is offering one tax-free weekend events during 2017. This yearâs Sales Tax Holiday is Aug. 11 - 13. As in previous years, the law exempts most clothing, footwear, school supplies and backpacks priced less than $100 from sales and use taxes, which could save shoppers about $8 on every $100 they spend.
North Carolina no longer offers a tax-free weekend. Sales tax holidays are designated periods when selected products are exempt from state (and sometimes local) sales taxes. The state of North Carolina repealed its tax-free weekend event when Governor Pat McCrory signed legislation in 2013 that also reduced corporate and personal income taxes. As a result, the state held no tax-free events during 2014, 2015 and 2016.
