You have started business activities and failed to apply for a business license in time. This is your mistake. From the tax point of view, as long as you have business activities, you should pay taxes according to the regulations. You will not not collect taxes because you do not apply for a business license in violation of regulations, that is, you will not reduce or exempt your taxes because of your wrong behavior. I suggest you apply for a business license quickly, and the punishment for operating without a license is very heavy.
