It’s another tax-free weekend in Texas. This time, water and energy-efficient products may be tax-free from Saturday through Monday.

Products that display the Energy Star logo can be purchased tax-free, including: programmable thermostats, air conditioners ($6,000 or less), refrigerators ($2,000 or less), ceiling fans, fluorescent light bulbs, dishwashers, dehumidifiers and washers (but not dryers).

This is the second year that products with a ‘WaterSense’ label or logo are tax free as well. These include shower heads, bathroom sink faucets and accessories, toilets, urinals and landscape irrigation controls.

The sales tax holiday also applies to water-conserving products used or planted for conserving or retaining groundwater, recharging water tables or decreasing ambient air temperature to limit water evaporation. These include mulch, plants, trees, grasses, soaker or drip-irrigation hoses and moisture controls for a sprinkler or irrigation system.

There’s no limit to how many tax-free items you buy during the sales tax holiday.
