Before you drop off your kids at Horry County schools, make sure you have South Carolina plates on your car.

The Horry County Auditor held a news conference Monday to let residents know investigators will be in school parking lots this week looking for out of state and expired license plates.

The law requires new residents pay a car tax and get their car registered within 45 days of moving to South Carolina.

Some of the money from that tax goes to the school system.

"About 80 or 85 percent of the money that we collect from out of state tags goes to the school board and therefore, you get better education and more teachers and stuff like that," said Tim Christopher, a field investigator.

Delinquent tax payers will first receive a notice. The next step is a warrant.

Last year, the auditors office collected almost $163,000 from more than 2,000 people with delinquent tags.
