• Tax Payable:If the tax liability is greater than the TDS, you will have a tax payable. You must pay this outstanding amount immediately and enter the payment (Challan) details into the ITR form before submission.

• Refund Due:If the TDS is greater than the tax liability, you are due atax refund, which will be credited to your verified bank account.⁶
