May be that the government is able to get some collections from the income tax.But this is an iota of the tax which is due.So what is happening?Large amounts are still being evaded.this money not braught to the market by the evaders.This amount is being tucked away in houses ,Bank lockers etc.If this amount is braught to market a huge demand can be created,and investment in Industry can be seen.This only canbe done by exempting the income tax.Do it for two years saying that the government will not ask for any details.Inflation also can be controlled by other methods.
