I mean, there are countries where tourists don’t have to pay tax on top of items (meaning they pay for it tax free given if they presented their passport upon purchase proving they’re merely only a visitor, that won’t work on expats though). There are countries who have tax refunds when visitors are leaving (basically reclaiming VAT whilst at the airport), they have already purchased the goods with VAT paid but gets refunded upon them departing.
IMO it should be the opposite: You should get a sales tax exemption if you’re a resident. The reason tourist-heavy areas have high sales tax is to capture more nonlocal money they can use to support local services.
Yeah, sales taxes is generally bad because it is regressive. The fact that it can capture revenue from non-locals is one of the main benefits.
