Friend you are referring to the following point:
Deficit financing to the tune of R. 3,0 billion per day which is the main cause of inflation would be stopped.
The above point on deficit financing suggests that PTI will stop money going towards servicing the national debt . Pakistan pays 3 billion rupees per day infrom interest and mark-up on its 60 billion dollar total loan from IMF, World Bank, Paris Club , Asian Development Bank and other financial institutions.
Therefore, in order to pay this interest on this massive loan - Pakistan has to inflict indirect taxation on the masses by increasing the price of commodities and increasing tax on petroleum products and utilities like electricity water etc - all of this causes inflation.
PTI will refuse to pay this interest on loans from IMF World Bank etc , so that the government does not have to burden the masses with increased prices. This can happen in the first 100 days.
Friend, income tax does not cause inflation. If people who have money pay their income tax, the government will not have to burden the poor. But people will only pay income tax to a credible government and to someone who they trust with their money. Its upto you to decide if you trust Imran Khan with your money and if you want to be live a life of a tax paying honest Pakistani.
