Purchase back-to-school supplies during your state's sales tax holiday.

If you’re already thinking of back-to-school shopping, you may get a price break in the next few weeks.

Though 45 states and the District of Columbia typically collect sales tax, 16 states have decided to either cut the amount of sales tax they charge or to not charge sales tax at all during various weekends this summer. 

While shopping, keep in mind that most states have limits on how much you can purchase without paying taxes. Tennessee, for example, forgives its full 7 percent sales tax on computers that cost up to $1,500. South Carolina, on the other hand, does not place a dollar limit (PDF) on eligible purchases—and even exempts add-ons such as clothing alterations and delivery charges.

You may not have to pay state tax, but you still could owe county and city sales tax. In Missouri, for instance, dozens of municipalities have opted to collect their local sales tax during the state sales tax holiday. 

The average family is likely to spend an average of $685 on back-to-school shopping this year, according to the National Retail Federation, a trade organization. Depending on where you shop, the savings could really add up.
