1, copy the tax first. Insert the tax control panel into the computer, open the tax invoice billing software, and enter the password to log in. Select "Tax Reporting Processing"-"Online Reporting and Copying" in the main interface. Click "Report Summary" in the pop-up interface. When finished, exit and close the billing software. 2. Then, file tax returns. Log in to the online electronic tax bureau, use the tax control panel to log in, and select "comprehensive declaration" in the navigation bar on the left side of the homepage, or click "I want to declare"-"tax declaration"-"comprehensive declaration" in the middle navigation bar in turn. Enter the declaration interface. After the test is completed, click Next, and fill in the "Detailed List of VAT Reduction and Exemption" and the "Main List of Small-scale Taxpayers" in turn. If the quarterly tax-free income exceeds 90,000 yuan, fill in the tax-free income in the column 1.3; If it does not exceed 90,000 yuan, fill in the income excluding tax in the column 1 1. When finished, click Next to submit the declaration. 3. Then click Next to fill in the attached tax and individual tax. If the quarterly tax-free income is less than 90,000 yuan, you don't need to fill it in and save it directly. Click Next. If the quarterly income excluding tax exceeds 90,000 yuan, the value-added tax amount shall be filled in the column 1. Personal income tax should also be filled in this way. When finished, submit the declaration and click Next to pay the tax. Inquire about the declared deduction. 4. Finally, liquidation. Re-open the fiscal invoice invoicing software, and select "Tax Reporting Processing"-"Online Reporting and Copying" in the main interface. Click "Write Back" or "Remote Clearing" in the pop-up interface. Do it. In most cases, the card will be cleared automatically after the system is opened. Click OK. There should be an interval of more than 2 hours between the completion of tax copying and filing, otherwise the system will not be able to automatically liquidate, and "one window comparison failed" will still be displayed, so it is necessary to take the tax tray to the lobby for manual liquidation. After clearing the card, click "status query" in the tax return processing interface, and you can rest assured that the lock date of the golden tax plate will jump to next month.
