Taxes are generally imposed by a government as a means to raising funds. Taxes generally have to do with a specific item, such as property tax. In the case of property tax, a percentage of each property owned by a citizen is taxed a certain percentage. Another tax can be the sales tax, in which each item sold and bought is taxed a percentile to be able to raise funds.
Essentially, taxes are imposed by the government to raise money to pay off it's debts.
