Answer:
proportional tax
Step-by-step explanation:
The description stated in the question is an example of a proportional tax. Like mentioned, this is a type of income tax system that enforces the same percentage tax rate to every single individual regardless of their overall income. This applies to low, middle, and high-income taxpayers. Therefore, if a low-income tax individual is charged 10% then the middle and high-income taxpayers will also be charged 10%.
