If I purchase from a seller online at 1:00 a.m. Friday, August 4, 2017 but that seller is located on the west coast in the Pacific Time Zone, should I be charged sales tax?
Yes. The time zone of the seller's location determines the authorized time period for a sales tax holiday when the purchaser is located in one time zone and a seller is located in another. In this instance, it is only 10:00 p.m. on Thursday, August 3, 2017 in the Pacific Time Zone. The sales tax holiday does not start until 12:00 a.m., on August 4, 2017.
