Should I send business tax returns if unofficial income(which is not shown) is much more than on which income tax is charged??

some people say that sending to much documentation is bad , this only apply , if that is the case , for the SPP applications.

Regarding financials , is always recommended to add everything that shows a source of money, for example: properties, bonds, car ownership, loans, slips, salary...
