The tax rate varies across the state, but exceeds 8 percent in some communities.
No tax will be imposed on computers up to $1,000, including tablets; and computer hardware, such as a printer, that costs no more than $500.
Also tax-free are school supplies under $30 and certain clothing and shoes up to $100.
Cell phones, iPods, and MP3 players are subject to taxation.
The conservative think tank Tax Foundation says tax holidays don't stimulate economic growth and are a political gimmick.
