Deductions

IN THE STUDY MATERIAL OF INCOME TAX IN CHAPTER DEDUCTIONS IN FEW DED'N IT IS WRITTEN IN TERMS OF TIME PERIOD.

FOR e.g

DED'N IN RESPECT OF ASSESSEE ENGAGED IN TELECOMMUNICATION SERVICES WILL BE ALLOWED IF IT IS PROVIDING TELECOMMUNICATION SERVICES FROM 1.4.1995 UPTO 31.3.2005.

WHAT DOES THIS STATEMENT MEAN.

I'M VERY CONFUSED.

THANKS A LOT.
