Why should i fill schedule al in itr4

Dear All,

fy 2014-15         ay 2015-16

I have income from proprietory business 3 lac

Income from Long Term Capital Gain 34 Lac (on which tax has been paid in full).

ITR 4 is showing your income exceeds 25 Lakh and Schedule AL has to be filled. 

My query is why I need to fill Schedule AL when my income is one time on which tax is paid at special rate and not regular. What if i do not fill in Schedule AL

Thanks in advance

regards
