Answer:
D. It makes all citizens pay the same percentage of their income in
taxes.
Step-by-step explanation:
A proportional tax system imposes the same tax rate for all individuals regardless of the level of income. For example, if the tax rate is set at 5%, all taxpayers will be taxed at that rate. A person earning $10,000 will pay $500 (5% of 10,000) while the one earning $100,000 ( 5% of 5000)will pay $5,000.
A proportion tax system is also known as the Flat rate system. It is easy to compute and implement. The propositional tax system may appear to be fair because it treats all taxpayers equally and encourages people to earn more. However, it places a heavy tax burden on low-income earners.
