Use of income tax returns(itr)

An income tax return is a document you file with the Govt Revenue Department  reporting your income, profits and losses of your business and other deductions as well as details about your tax refund or tax liability.

If we file ITR? we get tax refund from GOVT?

or just for proof we have to file every Financial Year?

if the filing entity has TDS acumulated balance, and unable to utilize the same, then refund is also there,
