Heavy penalty, imprisonment: Here is what happens if you don’t file ITR
All the salaried classes are required to file Income Tax Return (ITR) every year. The government has exempted those earning between Rs 2.5 lakh and 5 lakh but others are expected to file their income tax returns under the given deadline.
If the ITR is not filed at all, they will not be able to carry forward the losses of the current assessment year. Source - PTI.
