Up to certain extant (I think it is Rupees 2,50,000) no need to file any income tax return. Government of India has exempted this low income category from filing of Income Tax Return.
You say you do not have any income tax return. It means you must be falling under this category.
So I am unable to understand how some company can force to provide you Income tax return. Though they may ask for kyc. They are not an institution giving any loan / financing you. Just for refund asking ITR is really very disturbing factor.
If they want ,then you can File the ITR for nil or zro tax also. You can fill for 2017-18 year ,Date has beed extended for 31 August.
They are asking ITR-V as a document for taking loans from banks. As intentions are not clear regarding payment process. They have taken so much of time and did not repay my amount. If some body also provide ITR-V then that is not of any use for them, income tax department is going to set the inquiry so no any issues.
