You can claim a tax refund if you paid excess tax during the financial year.
It usually happens when the advance tax, self-assessment and/or TDS deducted is more than the net tax liability of a taxpayer.
You cannot claim a tax refund unless you file your ITR. Refund will be issued only after the income tax department (ITD) processes your ITR.
ITD is planning to issue refunds faster. However, it usually 3 to 6 weeks to receive a refund from the date of filing of the tax return.
