Legal subjectivity:
The sewage treatment fee is determined based on the principle of compensating the operation and maintenance costs of the sewage pipe network and sewage treatment facilities and making a reasonable profit. The taxes imposed on sewage treatment fees are income from qualified environmental protection projects. Starting from the tax year in which the project obtains the first production and operation income, corporate income tax is exempted from the first to the third year, and from the fourth to the sixth year. The corporate income tax will be halved every year.
