I'm going to tell you how to declare tax when I open my own restaurant. I hope I can help you. Specific operations are as follows: 1. Step 1: First, open State Taxation Administration of The People's Republic of China official website and select "Online Tax Service Hall".

2. Step 2, then click "Business Tax Declaration" of the restaurant.

3. The third step is to fill in the "taxpayer information" of Shaanxi Heying and Border Giant Industry Tax.

4. Step 4, then go through the "application form" for tax declaration, and you can declare tax.
