By the way Pakistani tax laws are also some of the worlds useless ones with giving the 'baseball bat' just to salaried ones and general consumer through indirect taxes. Business Man lot just believes in Rs.1000/ month retained lawyer and separate set of books and accounts for tax purposes.
Personally after paying tax on my salary income for 3 years and feeling discriminated (from business man lot) in term of tax changeability, i would gladly like to evade tax as much as possible (though impossible coz tax is with held at source by employer).
Some say Pakistan is among the countries where it is relatively easy to start up very small to small entrepreneurship due to 'other options' available for getting exemptions from various statutory requirements.
