AFAIK (I'm American), the UK has a VAT rate for any good a consumer might find in a shop: 20%, 5%, and 0%, depending on product type. Because this rate is country-wide, the manufacturer can include VAT in their RRP. For example, if I go to the Sony website, a PS5 is £479.99 incl. VAT. If I go to the Amazon UK site, it's £466, or 3% off, incl. VAT.

If we locate the same product on the Amazon US site, it's $499.99 before tax. Amazon has two choices: show their price before tax or require shipping information from the user to see a price at all. (An estimated geolocation is not precise enough to determine a price.) For most consumers, I suspect seeing a pre-tax price upfront is better than having to provide personal information to see a price at all.

That explains online sales, but let's address brick and mortar retail. Imagine you go to Best Buy to comparison shop against Amazon and the price says $550 including tax. Is tax on this item in this location 10%? Or is it 5% but Best Buy's base price is higher than MSRP? It's up to me to find out the local tax rate and do the math. Let's say they agree to price-match Amazon; the clerk will need a function on the register to input a pre-tax price to facilitate this.

So, given this complexity and disparity, US manufacturers list MSRP without tax. Retailers display pre-tax prices for marketing and competitive reasons, generally never exceeding MSRP. Customers have come to expect this nationwide, so changing now would be challenging. (There are other good reasons to stick with pre-tax, too. In grocery stores, for example, pre-tax prices are very useful for SNAP beneficiaries.)

Do I think it would be useful to display tax calculations on signage in-store? Absolutely, and for some goods in some states, they do. But without laws or customer demand, retailers have no incentive to put themselves at a competitive disadvantage.
