Your post shows the ignorance of how the tax law works. One fact there is you are by default expected to disclose all our income when you are filing your returns whether its going to be seen or not and its for your own good because if you choose to not disclose, you better be able to have other means of getting money to support your lifestyle and a backup to have enough in your bank account because if you don't, there will always be a connection. You earn salary, which is paid in your account, you are expected to file a return, the same thing with your company. The same thing goes to every company you visited to buy as little as groceries. So, its all connected when they have your time, you wish you didn't hide anything.
