Roundings in VAT calculation: Mathematically impossible prices?
There are a whole range of VAT-inclusive prices that cannot be mathematically arrived at if the tax is calculated from the VAT-free price. One example is 3.99. These prices are also possible, but then the VAT-free price must be interpreted as rounded.
In Europe there is VAT - in the US sales tax
In Europe, companies belonging to the production chain account for the VAT paid by the consumer to the state in proportion to their value added. The US sales tax, on the other hand, is billed entirely by the company that made the consumer sale. Sales tax is paid to local operators, not to the state.
History of taxation
Many of today's taxes were already in use in Antiquity. Deciding on taxation has moved from autocrats to parliaments and the level of taxation has risen. In earlier times taxes were used to wage wars, today taxes are used to maintain welfare states.
