Fairness and justice are important goals and cores values for pursuing an effective taxation system. However, for certain economic and social purposes, our nation implements extensive and long period tax deductions causing constant doubt of the equality of taxation. The tax deduction policies may be equitable to the past, but with the change of the environment, should the government carefully examine whether the result of the tax deductions has affected the fairness, justice and fiscal of the nation. If these deductions have already impaired the welfare of the nation, it is necessary to revise the taxation system and reconstruct the public value. The Legislative Yuan has passed ¡§Fundamental Regulations of Income Tax¡¨ also named ¡§Alternative Minimum Taxation, AMT¡¨ by the end of 2005. It is the first tax regulations passed by the Legislative Yuan in the last two decades. These regulations limit the deductions and compensate the deficiency of unfairness. Thus, this research will focus on taxpayers¡¦ recognition and support of the tax reform after the regulations are executed. Should people promote more tax reforms if outdated deductions exist? Therefore, by combining the questionnaires with the empirical analysis, gathering related discoveries and opinions, this research leads to a practical suggestion and provides a reference with the tax authorities to amend the tax deduction policies. According to the result, the tax experts and professionals agree that AMT meets the needs of tax equality and justice. Besides, nearly 60% of the interviewees think AMT is beneficial to our nation¡¦s finance. However, people recognize that negative effects and problems with the implementation of AMT should be overcome. People also highly expect to modify the outdated tax deductions. In conclusion, our research provides the following suggestions: 1. To thoroughly review and revise the outdated tax deductions promptly. 2. To review and amend the extent of the income tax deductions. 3. The review of investment tax credit is the main purpose of our tax reforms. 4. To prevent the incentive of tax evasion and discuss regularly about the existence or abolition of the AMT.
