Income Tax Refund, Self-Assessment Tax & Tax Payment Explained – TY 2026-27

What is Income Tax Refund?

Income Tax Refund occurs where the total tax paid or deducted by a taxpayer exceeds the actual income tax liability of the taxpayer for the relevant Tax Year.

The excess may occur on account of:

• TDS
• TCS
• Advance Tax
• Self-Assessment Tax
• Any other eligible tax payment

Upon completion of the process of Income Tax Return, the eligible excess may be refunded to the taxpayer.

What is Self-Assessment Tax?

Self-Assessment Tax refers to the net amount of income tax which needs to be paid by the taxpayer, after accounting for tax paid or deducted by the taxpayer.

Taxpayer has to calculate the total tax liability and deduct:

TDS + TCS + Advance Tax + Other Eligible Tax Deductions

The remaining amount, if any, will have to be paid by the taxpayer as Self-Assessment Tax, prior to filing the Income Tax Return.

When is Self-Assessment Tax Payable?

Self-Assessment Tax will be payable in the case where:

• Final tax liability is higher than TDS/TCS
• Advance Tax paid is lower than actual tax liability
• Additional tax becomes payable while preparing ITR
• Other tax liability continues to be payable
