Nowadays, the declaration of state and local taxes is through online declaration, online declaration should have CA secret key, that is, something like a USB flash drive, and also install CA assistant or other software on the computer. It's possible that the next one you get into already has all that. All you need to do before the 15th of each month is to plug in the CA key on your computer, go to the official website of the State and Local Taxation Bureau to declare and pay all kinds of taxes and fees, and then the Taxation Bureau will deduct the money from your bank account after you have successfully declared. Of course, the premise of this operation is that your enterprise has signed a tripartite agreement with the bank and the tax office, and the tax office entrusts the bank to deduct money from your company's account. If you still have to pay VAT, it depends on whether the company is a general taxpayer or a small-scale taxpayer, and whether it can issue invoices by itself. If the company is a general taxpayer and can issue invoices by itself, it should install the anti-counterfeit tax-control system on the computer and the invoicing machine on the computer. After the invoicing in the previous month, you have to clear the card operation in the current month, otherwise you can't open the invoices in the current month. The VAT declaration is also operated by logging into the official website of the IRS with CA.
