It's just American custom to exclude some taxes from the posted price. Many countries include all taxes in the price, something I've always wished we would do in America. After that, I'd love to see the elimination of the custom of always ending fuel cost per gallon in 9/10 of a cent.
Rounding sales tax on each item will often result in a different price than rounding once for the total. The store will collect the wrong amount of tax that way.
I don’t see why that would be the case? In my country, most prices with VAT (which is what you’re charged) are nice, round numbers, but not the price without VAT.
I suppose the stores set a target price, and then adjust it a bit to make the price + VAT a “nice” number.
Is there a reason that couldn’t be done to make all prices + VAT multiples of 5c?
The local tax is set by multiple independent tax authorities that change their taxes independently, the tax you see is the aggregate of those independent authorities computed separately, which do not coordinate with each other.
Some of these taxes are conditional at point-of-sale, late-binding the taxes, such that different customers are subject to different rates across these tax authorities such that it is unlikely to round to exactly 5c.
It is widely illegal to not display the true price and taxes paid separately. Trying to retcon a price and taxes for rounding purposes that is also strictly consistent across customers so as to not violate the law is not trivial.
And on top of all of this, the Federal government does not have the authority to regulate the way States and various locales structure their sales taxes. It is a herding cats problem.
Lots of localities total taxes aren't whole percentages so it potentially gets tricky making prices work in those systems such that you can make whole 5 cent tax included prices with whole cent base prices. Do most POS systems support arbitrary precision item prices?
Just show the price including tax. (half-sarcastic, because obviously that would be an unpopular change for sellers because it makes the visible number go up, but it would solve two problmes...)
They could still set the post-tax price to something that results in round numbers, at downside of the pre-tax price having more decimals.
With a tax rate as precise as 1000ths of a percent in many jurisdictions*, you'd need extreme precision on the price tag (e.g. $11.798625), OR you need to substantially overcharge for tax (rounding up the tax to the penny or nickel on each individual item, instead of on the total of ALL items).
And sales tax rates can even be different from ONE CITY BLOCK TO THE NEXT.
So, lobby for changes to the structure of those taxes so that's not a problem. Tthe simple solution is changing them from surcharges adding a percent onto posted prices to making them a percentage taken out of the posted price; so that coin availability is only an issue in the improbable event that you are paying your sales tax bill in cash.
Of course, retailers don't want tax-inclusive posted prices, but... ::shrug::
With some 5th grade algebra, one can adjust the total of a transaction to result in a round number after taxes.
Besides that, the law (at least where I live) is that the tax must be paid, but it does not specify by whom. It's completely feasible for a retailer to pay the 2 cent difference in the tax and charge the customer a round number.
Is this really the state of American education where a percentage calculation makes a very simple situation literally impossible? You can think of no other way to overcome the complicated calculations of checks notes x times 1.06?
Even with just a 6% tax, you end up with prices that need 4 digits of precision after the decimal (e.g.: $11.6494). That issue extends over a wide range of pre-tax/input prices, so one would have to DRASTICALLY change the prices so that the price including 6% tax rounds to even a penny, let alone a nickel.
While you could calculate a price that (after tax) would round a single item to the nearest nickel, it's completely IMPOSSIBLE to do so with unknown numbers of multiple items.
In addition, tax rates in the real world aren't just single-digit percentages. They have precision of 1/1000th of a percent, making such a calculation much more challenging.
Arizona: 10.725%
Hawaii: 4.712%
Minnesota: 7.875%
etc.
And sales tax rates can be different from ONE CITY BLOCK TO THE NEXT, so a company with more than one location would find it IMPOSSIBLE to advertise their prices at all.
State and local taxes make this infeasible

I'm in Ireland where EU law mandates posted prices include all taxes and charges, and fuel prices are still advertised with a .9 or .8 at the end.
They're selling a liquid, so even if it were all priced in whole cents you'd have to deal with fractional cents.

Several reasons, it really is a mess.

Retailers don't, like, have to add sales tax on top of listed prices.
They just have to pay it.
No, it's illegal in many, looks like most states:

Oh no, a made up problem that's easily solved by changing the price slightly in any direction, whatever will we do.
It's the same way with the penny.
Tax on a 0.99 item isn't coming out to an exact penny multiple.
So stores are already dealing with this situation
