      I saw an interview with an economist years ago where he said that if we just followed the accepted rules of rounding (1-4 rounds to 0, 5-10 rounds to 10) then it would work out about the same. In reality I’m sure companies would just pocket the extra money

        They already do with sales tax. ( If the tax works out to a fraction of a cent, almost every register or POS system will round up…it’s a tiny amount per transaction, but it does happen and adds up over daily, weekly and monthly transactions)

          I write POS software, and have written tax calculations that cover about 30 states, and several CA provinces.

          While we do have to round (always up) when calculating sales tax, there’s no way for the business to figure out how much that rounding would be, since it’s just added to the tax collected.

          And in all states that I’ve worked with, a business has to pay what they collected (even if they over collect), and can’t just calculate a percentage of total sales (since many states have tax tables, rounding rules, or 3-4 decimal tax rates, and not a flat percentage tax).

          So it’s actually the government that gets the benefit of the rounding.

            Is that why sales tax is always on its own line on the receipt and it’s own account number on the trial balance?

            I don’t know if you’re in any position to suggest decisions, but your software is often run on subpar hardware. Going to touchscreens doubled our call time, it was because of the half second or so of loading between touches. It couldn’t be used naturally because of the delay.

      We follow normal rounding rules in Canada. 1, 2 round down to 0. 3, 4 round up to 5. 6, 7 round down to 5. 8, 9 round up to 10.

      Can you game the system? Yes!

      As a business, make sure all your prices (plus tax) come to a price ending in 3, 4, 8, or 9. When consumers buy a single item you’ll get the rounding up (edit: if they pay cash) and make sweet, sweet profit. But if they buy more than one item, you’re SOL on controlling the rounding.

      As a consumer, you have way more control. First, pay with cash whenever the price will round down and you can probably “profit” 5 or so dollars a year. (Assuming you pay with cash on or two times a day, saving 1 to 2 cents each time.) Pay with credit or debit each time the price will would round up.

      Second, you can get real fancy. You can learn tax rules in depth so you know what items will or won’t be taxed and at what rate (we have federal and provincial taxes but they don’t apply to everything and they don’t follow the same rules on what is taxed.) But, you can use this info to always know what the final bill will be and always buy combinations of items that end in 2 or 7 (or 1 and 6 if you’re lazy) and always pay cash. You can profit like $20 a year or something doing this.

      In reality? No one gives a shit until that one rare time you’re paying with cash and it rounds down. It’s your lucky day and you do the Six Flags Man dance. It’s like finding a penny and picking it up.

      There’s still a fuck ton of pennies in circulation and on the ground, unless they consider them no longer legal tender we’ll have plenty.

      However, if we end up following how Brazil does it, in my experience, it depends on the person/vendor and the amount. If you buy something that’s like R$3,99 you’ll usually get give them R$4 and that’s it. I’ve also had it where I’ll pay for something that’s say R$4,89, give them R$5 and get 15 or 25 centavos back. Could also depend on what’s in the drawer at that time.

      Corporations will 100% pocket the difference at first, but once it becomes a normal thing to do the rounding I’ll wager it’ll fall to the Brazilian method, especially with local businesses or vendors.
