When the status displays ‘processed with refund due’, it means that the tax return has been processed and the tax refund will likely be issued to you in 20-45 days after the ITR processing date. If the status shows ‘refund rejected’, it could mean that your tax liability has been re-calculated
If the tax you have paid in a financial year exceeds the actual tax liability, the Income Tax (IT) department refunds the excess tax paid after you have filed your income tax return (ITR). You will know if there’s a tax refund due while preparing your ITR. However, the final refund amount and whether you are eligible for one is determined only after the ITR is processed by the IT department.
It’s been nearly 40 days since the ITR due date has passed and if you still haven’t received your refund, you should check its status on the e-filing IT portal or tin-nsdl website.
