Cities and counties wanting to opt out of the 2006 Missouri Sales Tax Holiday are running out of time to do so. Maura Browning with the State Revenue Department says written correspondence must be sent to the Department by the end of business on Tuesday. Any city or county that does not approve a motion to opt out will automatically be included in the Sales Tax Holiday, which is being held for three days – August 4th, 5th, and 6th. Items covered by the Sales Tax Holiday include clothing under $100 per item, school supplies under $50, computer software under $350, and computer equipment that costs $3,000 or less. Even in cities and counties that opt out, the state sales tax of 4.225 percent will be lifted on the targeted items.
