I wanted to start working in the US in H1 from October 2016 only. Should I apply for FY 2016 or 2017

I am little confused as applying in the April 1st week of 2015 for FY 2016 means my approx start date on approval of visa is October 2015. I cannot start in october 2015 due to my family reasons. So, Applying for FY 2017 by April first week 2016, when will be my start date ? Please help me with an answer. Thank you very much.

If your company files for you in April 2016, and if your H1 gets approved, you may start working in USA from Oct 2016.

Thank you very much for your guidance sir.
