Did not file null return

You can file for FY 2013-14 and FY 2014-15.  For the earlier years, you cannot file suomoto.  Further, if there is no income, there is no regulatory requirement for filing of the return

Thanks for the reply.

I was worried because I heard THE FINANCE ACT, 2012 says all foreign assets should be reported even if they have no income.

absolutely priya.  the mandatory requirement is there.  But only for the years where your tax status is resident. So, depending on days spent in and outside India, first you need to check your tax status.  Only after determination of the tax status, the applicability of the said tax law can be checked.

Having said above, you are definitely getting covered under this amendment for last two years.
