Explanation:

Taxation can be defined as the involuntary or compulsory fees levied on individuals or business entities by the government to generate revenues used for funding public institutions and activities.

The different types of tax include the following;

1. Income tax: a tax on the money made by workers in the state. This type of tax is paid by employees with respect to the amount of money they receive as their wages or salary.

2. Property tax: a tax based on the value of a person's home or business. It is mainly taxed on physical assets or properties such as land, building, cars, business, etc.

3. Sales tax: a tax that is a percent of the price of goods sold in retail stores. It is being paid by the consumers (buyers) of finished goods and services and then, transfered to the appropriate authorities by the seller.

The prefix retro-makes the phrase "retroactive tax" mean "pay taxes back." because retro connotes something that has happened in the past.

This ultimately implies that, the tax applies to income or transactions that have taken place in the past.
