Understanding Self Assessment Tax: Simplified Explanations

In this blog, we will delve into the definition, purpose, and significance of self-assessment tax payment, shedding light on its role in fulfilling tax obligations and ensuring adherence to tax regulations.

What is a Self Assessment tax payment?

Self Assessment Tax pertains to the tax payment made by an individual based on their evaluated income, taking into account deductions for Tax Deducted at Source (TDS) and Advance Tax.

Let us explore how to pay self-assessment tax online by apprehending the steps involved:

The filing of self-assessment tax online can get conveniently completed by individuals, utilizing the following outlined steps:

1) Begin by visiting the official website of the Income Tax Department of India, which provides a user-friendly platform for managing your tax-related matters.

2) Sign in to your account and navigate to the e-Pay taxes option. This will redirect you to the official website of the National Securities Depository Ltd. (NSDL), ensuring a secure and seamless payment experience.

3) To proceed with the online payment of Self Assessment Tax, individuals should choose the designated option identified as "Challan no. /ITNS 280". From there, you can opt for the specific choice labeled "0021 (other than companies)".

4) Fill in your personal details, including your name, address, contact information, and PAN card number, ensuring accurate identification and record-keeping.

5) Choose the appropriate assessment year for which you intend to make the payment, ensuring that your tax payment is correctly allocated to the relevant financial year.

6) Indicate that the payment is for Self Assessment Tax, demonstrating your commitment to fulfilling your tax obligations accurately.

7) Select your preferred bank from the list of available options for making the payment, granting you the flexibility to use your trusted banking partner.

8) Once you have chosen your bank, enter the precise amount of tax payable, ensuring a timely and accurate submission.

9) Upon confirmation, you will be redirected to your chosen bank's payment page to complete the transaction process securely and conveniently.


After successfully completing the payment, a detailed challan will be generated, providing you with important transaction information such as a unique CIN (Challan Identification Number) and the name of the bank involved. This serves as tangible proof of your tax payment.


It is advisable to keep a soft or hard copy of the generated challan for future reference, ensuring easy access to transaction details whenever necessary. Within a few days, the challan details should reflect on your Form 26AS, which is a consolidated statement of tax credits. If the details do not appear, you can provide the necessary information while filing your Income Tax Return for the corresponding financial year. This step ensures accurate record-keeping and facilitates the reconciliation of your tax payments.

Unfolding scenarios when paying Self Assessment Tax becomes mandatory:

  1. Self-assessment tax is required when a taxpayer unintentionally fails to include certain income while calculating the amount of advance tax payable.

  2. The need for self-assessment tax arises when a taxpayer receives unforeseen gains or income from sources that are not subject to Tax Deducted at Source (TDS).

  3. Filing self-assessment tax becomes necessary when the deduction of Tax Deducted at Source (TDS) is either completely omitted or deducted at a lower rate than what should have been applicable.

These circumstances require individuals to file self-assessment tax in order to rectify any discrepancies between the tax already paid and the actual tax liability. By addressing these situations through self-assessment tax, individuals can ensure accurate fulfillment of their tax obligations and proper adjustment of any underpayment.

This is crucial to avoid any unnecessary burden of interest and penalties.

Furthermore, it is essential for taxpayers to carefully review and verify the details of their self-assessment tax payment mentioned in the challan.

This verification process is important to maintain accuracy and integrity in the records of tax payments.

The technical essence of Challan 280 lies in its versatility, as it covers multiple types of tax liabilities in a single form. This allows individuals to conveniently make payments for different tax categories without the need for separate forms. By utilizing Challan 280, taxpayers can ensure compliance with their income tax responsibilities in a streamlined manner.


What are the potential consequences if an assessee provides an inaccurate self-assessment of income and tax amount payable in their tax return?

If an assessee inaccurately assesses their income and tax liability in their tax return, it can have significant repercussions. Under the provisions of the Income Tax Act, of 1961, taxpayers are granted a period of 15 days from the filing of the return to rectify any errors. However, failure to rectify these inaccuracies within the stipulated time frame will result in the filed return being deemed defective, potentially leading to further consequences or penalties imposed by the tax authorities. It is essential for taxpayers to ensure the accuracy of their self-assessment in order to avoid such complications.

Payment for self-assessment tax should be made when the tax amount paid through TDS/TCS or Advance Tax falls short of the actual tax liability.
