However, the reason I think stores do this is: If store A is selling candy bars for $1 (+ $0.05 tax at register) and store B is selling candy bars for $1.05. Most people would buy their candy from store A because their prices are lower.
The situation where it comes up is the idea of an American VAT. Because it applies the tax before the store even sees the good, the tax ends up baked into the price. And people like Grover Norquist have argued against a VAT specifically because of that: "The VAT is embedded inside the price of a good (as opposed to the U.S., where sales tax is transparent and on top of the price). As such, people forget they pay it, and European governments have found it too easy to raise the tax repeatedly over time."
If the business did not collect taxes then you the customer owe that to the state still and are suppose to self report that and pay the owed taxed annually
This is the same as Tax withholding from a paycheck, you owe the taxes but your employer is collecting and forwarding them to the government on your behalf, the big difference here is the purchases are not tracked by individual tax payer
Interesting. But do people actually do this in practice? I wonder if states report what percentage of sales tax comes from businesses vs individuals.
Before 2018 or 2019 unless a business had a physical presence in the state it was outsize the reach of that states laws on taxation, as the Federal government has the exclusive domain of regulating interstate transactions under the US Constitution.
However in 2018 or 2019 the Supreme court has ruled that a business shipping into a state provides enough "nexus" for a business to fall under state regulations on sales tax collection. All but one state now require any business shipping a product into the state with a total sales volume of more than $600 for that state must collect sales tax, one state says any sales at all you must collect.
So the "loop hole" of buying from out of state to avoid state sales taxes no longer exist as almost all businesses now need to collect all taxes for all taxing jurisdictions in the US of which there are around 10,000 different tax jurisdictions as many area's have city and/or county level taxes in addition to the state taxes making this is very complex issue
Companies like Amazon and Walmart in the past have advocated for some kind of National Standardization of Sale Taxes but that largely has gone no where as many states make up the majority of their revenue from 2 places, Property Taxes and Sales Taxes where the majority of Income Taxes go to the Federal Government
>>I wonder if states report what percentage of sales tax comes from businesses vs individuals.
Most states do have detailed reports of where sales taxes come from, in my state over 70% of sales taxes come from the sale of Automobiles as an example
