Classify tax as to determination of amount?

Taxes can be classified into two main categories based on the determination of amount: fixed taxes and variable taxes. Fixed taxes are set amounts that do not change with the taxpayer's income or circumstances, such as certain property taxes. In contrast, variable taxes, like income taxes, fluctuate based on the taxpayer's earnings and financial situation, meaning the amount owed can vary significantly from one individual to another. This classification helps in understanding how tax burdens are assessed and the equity of the tax system.
