This sales tax is something almost all states already exempt data centers from, because they think it's so much it'd be onerous. Loudoun County, which gets $1.3 billion in tax revenue from data centers annually, doesn't charge a sales tax. It's technically true that this is "losing the state that much money every year" but only in worlds where the big additional tax doesn't scare any data centers away from the state.
These are the numbers we have for how much a $1 billion data center would be taxed in different states each year. The yellow is this sales tax. Notice that in most places data centers aren't charged it but are still taxed a lot.
