How do the types of OKVED activities affect the taxation of individual entrepreneurs?

Question

Electronic accounting

I have a question about the types of activities of OKVED. Let's say I open an individual entrepreneur under a simplified taxation system and the main activity will be the development of web and mobile applications (code 72.20). And as additional ones: Advertising (code 74.40) and Online store (code 52.61.2).
If I do not conduct additional activities, will this affect taxation?
And the second question, let's say, when I start to conduct activities in an additional type of activity, for example, an online store, then how will I have to indicate this in tax reporting when submitting tax reports?

Answer 1

1) NO
2) it is not necessary to indicate, as far as I remember, about the types of activities only in statistics, like data goes

Answer 2

You can indicate any activities that you plan to engage in now or in the future. You can operate on them or not, it does not matter, because. according to the simplified tax system, actual income is taken into account. But it is impossible to engage in activities that were not indicated, so indicate with a margin.
