You just dug yourself into a hole. - When I wrote 100 - it didnt mean "one item" - let me simplify. - according to what you just said.
you claimed that you earn Rs 5 from a juice box, how much income tax did you pay on this Rs 5/-
now is it simple for you or you want the "aratt" (broker) wali explanation.
btw - no one asked you for your income register as it would be invalid anyway (my 6 yr old daughter can claim 700 billion dollars with her crayons and a paper - its not valid)
when I put that question of income asked by any entity - e.g. getting a visa for a country and you have to prove your income/assets etc. - the embassy/consulate does not give a damn of your useless self made register.
The papers they want is the yearly income tax filing, that is your actual income because the "Federal Govt" has "verified and recorded" it - more simply, when in USA any bank asks for your income of last 3 years I just pull out the counterfile of my yearly taxes and give them that, its 100% accepted at face value.
same in UK (when I lived there) - same in all other countries where I lived or my family lived, I still have all income tax returns of my father (hes been dead since 2011 btw)
exact same in Pakistan - when I got my visas for any place I just handed the income tax returns of FBR as supporting evidence.
