Vermont extended its July holiday period an extra five days for sales of energy-efficient appliances.

Sales Tax Holidays have become a popular promotion. Originally intended for back to school supplies including computers, some states are extending the temporary tax-breaks to energy efficient appliances. This August, thirteen states and the District of Columbia will hold some sort of sales-tax free period. Local sales taxes may continue to be imposed in some places, however.

The most popular new category, reflecting concerns about the high cost of energy and the state of the environment, is for holidays for energy-efficient products. Vermont extended its July holiday period an extra five days for sales of energy-efficient appliances. West Virginia will have a new sales tax holiday for energy-efficient products in September, followed by Georgia and Virginia in October, which have expanded existing holidays for these products to include water-efficient products. North Carolina will hold a new holiday in November to encourage energy-conscious purchases.

Missouri will join the group in April 2009 with a new holiday for energy-efficient products. Texas plans to hold its second such holiday next Memorial Day weekend. The South Carolina Legislature overrode the Governor's veto to create a new holiday for energy-efficient products lasting the entire month of October 2009. Looking far ahead, Maryland plans to join the club with a holiday in February 2011. Connecticut, however, which had an energy-efficiency holiday for four months in 2007, does not have any further ones scheduled.

Sales Tax Holiday Changes for 2008

Two big states are missing from the usual group of states offering tax holidays this August. Florida and Massachusetts are not participating in 2008 (although last-minute action by the Massachusetts Legislature is not out of the question).

"Tight budgets in both states are blamed for their legislatures' reluctance to forego the sales tax revenue this year," said Daniel Schibley, CCH senior state tax analyst.

Vermont, on the other hand, moved ahead of the pack with a broad-based holiday in July, the state's first entry in the holiday sweepstakes. The Green Mountain State suspended sales tax for two days, July 12-13, on sales to individuals for personal use of most items priced $2,000 or less.

Maryland, meanwhile, which suspended its annual August back-to-school holiday last year, plans to return with a week-long holiday, but not until August 2010.

Hurricanes and Guns

Some states hold special-purpose holidays outside of the mainstream themes of back-to-school and energy efficiency. Louisiana and Virginia continued to hold tax holidays for hurricane-preparedness supplies in the spring of this year. Florida, however, which has held a similar holiday in the past, opted out in 2008.

Unique in the nation, the South Carolina Legislature, overriding another veto, enacted an annual holiday for sales of handguns, rifles and shotguns during what it dubbed the "Second Amendment Weekend" -- the Friday and Saturday following Thanksgiving.
