In order to facilitate taxpayers to pay taxes, most tax service offices keep the existing tax service places and locations unchanged. Another direct change is that taxpayers will reduce the submission of tax information. The provincial tax authorities sort out the list of projects with the same business of the original national tax and local tax, integrate the submitted materials and file them in a unified way, so that taxpayers only need to submit a set of the same materials and apply for the same tax-related projects at one time.
