This weekend Central Missouri shoppers won't be paying the 4.225 state sales tax on back-to-school purchases.
It's the ninth annual tax break given to parents who want to save money on computers, clothes and school supplies.
Everyone throughout the state will get the full break on the state's 4.225 percent sales tax on eligible purchases.
The three-day state sales tax holiday on certain items only starts at midnight on Friday and continues through Sunday.
Most Missouri cities and counties that impose local sales taxes are not participating in the tax savings for back-to-school shoppers.
Central Missouri cities not participating in the back-to-school sales tax holiday include Fulton, Kingdom City, Holts Summit, Jefferson City and Columbia.
Counties not participating include Callaway, Cole and Boone.
"Saving more than 4 percent is significant, especially on more expensive items like computers," said Alana M. Barragan-Scott, director of the Missouri Department of Revenue.
