Let me begin by
thanking you both for correcting me in this calculation, this is not sarcasm. I really mean it. Not just for the favor you've done for correcting me, but also
literally exhibiting my point i.e. the taxation system is too complex.
Here are the current figures of education in Pakistan.

So here is my question,
do you really expect that a person who hasn't even studied past sixth grade will know how to compute the figures of output tax and the input tax along with the tax due whilst passing the rest to the next intermediary?
That 10% markup was a supposition to simplify the calculations. Here is the problem though, unless the business itself wants a model where it is integrated right down to the retail, there will most definitely be middlemen. That's just the reality of the situation. Drastically changing that will present a whole new labyrinth of problems.
As per today's exchange rates 50K is a mere $ 316 dollars, and you want businesses that sale laptops, tv's, fridges, washing machines, furniture etc etc. to document more or less every customer they get for the government? How about the government devises ways to document the money trail through alternate ways such as debit/credit transactions etc. Both get you the same results i.e. a money trail, instead of putting the burden on a business, which generates economic activity and employment, the same employment rates that the political class likes to boast about come election season.
Agreed, the businesses should most definitely be brought in the tax net and be registered. No one is arguing that businesses shouldn't be brought in to the tax net. It's the mechanisms that need reform. Following is something that might interest you.
