The research on the credit of tax of tax law is made because: First, at the macro level, the rights and obligations between taxpayers and tax payees are very asymmetric.

对税法的税收信用进行研究主要基于：一是从宏观层面讲，纳税人与征税人之间权利和义务关系极不对称，纳税人享有权利过少，总是处于服从和不被尊重的地位；二是从权力层面讲，征税人自由裁量权力过大，纳税人对征税人的信任度降低，导致双方税收信用下降；三是从利益角度过分强调国家对纳税人部分权益的无偿强制占有，致使纳税人为追求利益最大化而采取法律禁止的偷、逃、骗、抗税，带来纳税人的反感和反叛，无税收信用而言。
