i am working in bank from the past 2 months where my current employer is asking me medical bills to get tax exemption. but if u dont submit then i have to personally file my returns to get that exemption. i didnt have time to file my returns. also somebody told me that ur current employer will file ur complete returns as per the information they have. so for that u need to get salary certificate frm my previous employer(or any other certificate i dont know.. plz tell me that too). in addition to tht certificate all my income frm other sources(if any) and all investments made in the current year(whether in mf or insurance premium).... if all this is correct then do i need to submit all this information with proof like receipts or only informing on a paper will do??
