Tax reform is subject to certain limitations, the most important of which is that it should not result in a significant change in the government's revenue. This means that any proposed changes in tax policies must be carefully evaluated to ensure that they do not cause a significant increase or decrease in the funds available for government spending. As such, policymakers must consider the potential impact on revenue when designing and implementing tax reform measures. It is vital to strike a balance between promoting economic growth and maintaining stable government finances. Therefore, any modifications to the tax system must be approached with caution and thorough understanding of its consequences.
