Why did I declare the company's national tax and send a message saying that I didn't declare it? What happened?

What is the date of your declaration? Because it was postponed this month. You declared it in the extension. It doesn't matter. The notice issued by the tax bureau system is a reminder of the date of issuance. Doesn't mean you haven't declared it. You can check with the tax bureau. Don't worry if you do. I've been in your situation. I have already declared it, and the legal person's mobile phone also received a text message reminding me that I didn't declare it. Hehe, brother is not worried.
