The Senate has approved Senate Bill 228  which designates one weekend a year where as a tax-free holiday for gun sales.  The bill sponsored by Sen. Brandon Creighton (TP-Conroe) exempts  firearms, ammunition and hunting supplies from sales tax during the last weekend in August.  Creighton calls it a Second Amendment tax holiday weekend.  Part of the rational for the sales tax exemption stems from a similar tax holiday that occurs one week earlier in Louisiana.  Proponents claim that Texas businesses near the Louisiana border lose considerable sales because of the tax disparity for that one weekend.  The Legislative Budget Board estimates that Texas will lose over $3.5 million in sales tax revenue each year if Creighton’s bill becomes law.
