We should also start requiring businesses to list the after tax price too.
The U.S. has tens of thousands of tax districts. Showing the price exclusive of taxes keeps taxes transparent and allows consumers to make direct comparisons between the prices of products across different regions.
This would be for in person sales. Obviously wouldn’t work online.
It even breaks down at a local level. It would be hard to make a direct price comparison between doing your grocery shopping in one county vs another if they applied different local taxes, for example.
I'm not understanding this. Why would someone care about doing a "direct price comparison" between two prices they're not going to actually pay? The final price (including tax) is what matters to consumers.
Because by displaying the base price and itemizing taxes separately, consumers are more informed about the components of the final price that they pay. It's a more straightforward and transparent pricing system; it ensures producers cannot artificially lower their advertised retail prices by selectively misapplying or excluding certain taxes and gives consumers full transparency into the taxes they are paying (which should be important to a lolbertarian.)
