After the anti-counterfeiting billing system successfully copied the tax bill, why should it be declared online? I didn't declare it online.

The anti-counterfeiting billing system copies the tax return form and uploads the billing content of the current month in the tax control machine to the tax bureau switchboard.

The purpose of online declaration is to upload the output tax, input tax and financial statements of the month to the switchboard of the tax bureau for comparison.

If there is no online declaration, it is impossible to compare and pay taxes. The management of the tax bureau will definitely contact your unit.

Follow the process every month. If there is any mistake, please consult the local tax hall.
