Under House Bill 128, which was sponsored by Rep. Lynn Smith, R-Newnan, retailers will not charge the state's 4-percent sales tax on items like school supplies, clothing, shoes and computer equipment from midnight on Aug. 2 to midnight on Aug. 5.
Local sales taxes still might apply.
The state first approved the sales-tax holiday five years ago to pump up a slow economy, and it has been renewed every year since.
The law also temporarily wipes out sales taxes on energy-efficient products, from compact fluorescent light bulbs to Energy Star-designated appliances, as long as the purchases are $1,500 or less.
The sales-tax holiday to promote energy saving is scheduled for midnight on Oct. 4 to midnight on Oct. 7.
