1. What is the purpose of the carryback and the carryforward provisions in the tax law?

Every student is required to make a table consisting of 5 years of data starting from year 2015 to 2019 regarding

operating income (assume values and must be in PKR) and then implement tax law over it (tax table is available

in ppt+book). In couple of years show operating income and over some year a loss, and then properly

incorporate carryback and carryforward of loss via solid numerical values you assumed.
