The billing system needs to upload invoice summary every month, log in to the billing system, click Invoice Management, and then click Summary Upload. If there is no summary upload, the tax control equipment will be locked and need to go to the tax service hall to unlock it.

Matters needing attention in uploading invoice summary are as follows:

1. Under normal circumstances, please don't click the operation.

2. The clearing of tax returns must be completed within the monthly tax return period (generally 1- 15, which will be postponed in case of holidays), otherwise the invoice cannot be issued and will be locked after the tax return period;

3. Make sure that the date of the computer is the current date, otherwise the billing system can't synchronize with the server, and the test of connecting to the server is successful;

4. Users who declare monthly must first declare and summarize, then send all the declaration forms on the tax platform and declare successfully, and then clear the card after entering the billing again;

5. If the invoice opened last month is not uploaded successfully, the system will not move the tax payment card around, and the offline invoice of last month must be uploaded successfully.

Taxpayers should file tax returns on a monthly basis, and the reporting period is from 1 to 15 of the following month. If the last day is a legal holiday, it will be postponed to 1. If there are legal holidays for more than 3 consecutive days from 1 to 15 every month, it will be postponed according to the number of holiday days. If a taxpayer fails to file a tax return and submit tax information within the prescribed time limit, or a withholding agent fails to submit a tax withholding report and relevant information to the tax authorities within the prescribed time limit, the tax authorities shall order it to make corrections within a time limit and may impose a fine of less than 2,000 yuan. If the circumstances are serious, a fine of not less than two thousand yuan but not more than ten thousand yuan may be imposed.
