Many of us would remember having been scared watching the 1997 Hollywood blockbuster, I know what you did last summer.

While the mystery movie and its sequels, I still know what you did last summer and I’ll always know what you did last summer, had we scared out of our wits, it is now time to be really frightened and petrified, if you have earned income in India and have not filed your return of Income.

The Income Tax department, through its non-filer monitoring system, has identified about 13.7 million people with potential tax liabilities who have not filed their return of income.

In plain and simple words, it means, they know what you did last year.
