What is the reason why the enterprises that file tax returns have no operating income?

Operating income refers to the total inflow of economic benefits formed by enterprises in their daily activities such as selling goods, providing services and transferring the right to use assets.

The classification of operating income can be divided into main business income and other business income according to the primary and secondary business of an enterprise.

Profit is the balance of income from selling products after deducting costs, prices and taxes.

Relationship:

Profit is the income from all business income minus product cost, sales cost, management cost and tax.

Operating income = main business income+other business income

Enterprise has no operating income:

1, withholding income tax, tax evasion

2. The sales ability of enterprises is poor, and there is no market for goods.
