Self Assessment in Income Tax - What is Self Assessment Tax for Salaried Employees?
Self-assessment tax is the balance income tax that a taxpayer must pay before filing an Income Tax Return (ITR) when the total tax liability exceeds the taxes already paid through TDS, TCS, advance tax, or other tax credits. Under Section 140A of the Income Tax Act, this tax must be paid along with any applicable interest before submitting the return. If you have additional tax due after calculating your final income for the year, you need to pay self-assessment tax to avoid notices, interest, and delays in ITR processing.

However, since many taxpayers are still familiar with the terms Financial Year (FY) and Assessment Year (AY), this guide continues to use them for easier understanding.
- The new Income Tax Act has renumbered most of the sections and simplified them by reducing the number of sections, schedules, etc.

What is self-assessment tax?
Self-Assessment Tax (SAT) is the amount that an assessee (taxpayer) pays on their taxable income after accounting for Advance Tax and Tax Deducted at Source (TDS) for the given financial year. Individuals who are required to file income tax returns are generally liable to pay self-assessment tax before submitting their returns. This payment can be made using Challan 280, which is also used for e-filing income tax.
Self-assessment tax does not have a separate due date under the Income Tax Act. However, it must be paid before filing your Income Tax Return. Any delay may result in additional interest under Sections 234A, 234B, and 234C.
Here's a more detailed explanation:
- Definition of Self Assessment Tax: Self-Assessment Tax refers to the additional tax payment made by taxpayers to cover any remaining tax liability after accounting for Advance Tax and TDS. It is a way for individuals to ensure they meet their full tax obligations.
- Applicability: Individuals and entities who are obligated to file income tax returns are usually the ones required to pay SAT. This includes salaried employees, business owners, professionals, and other income-earning entities.
- Payment Method: Taxpayers can pay their Self-Assessment Tax using Challan 280, which is a form that allows for the convenient payment of taxes to the government. This form can be used for both physical and online payments.
- No Specific Deadline: Unlike Advance Tax, which has specific payment deadlines throughout the year, Self-Assessment Tax is calculated at the end of the financial year. There is no fixed date associated with SAT payments. However, it is crucial to understand that taxpayers must settle their SAT before filing their income tax returns to avoid incurring interest on the outstanding tax amount.
- Importance of SAT: Self-Assessment Tax plays a vital role in ensuring that taxpayers meet their full tax liability for the financial year. It bridges the gap between the total tax due and the tax already paid through TDS and Advance Tax. Filing the SAT and paying the outstanding tax amount is a legal requirement, and non-compliance may result in penalties and interest charges.
- Completing the Tax Cycle: Self-Assessment Tax is an essential step in the overall income tax cycle. After computing their tax liability, taxpayers should account for any additional tax they owe, which could be the result of omitted income, unexpected gains, or TDS discrepancies. By fulfilling this obligation, taxpayers can complete the income tax process accurately.
Characteristics of self-assessment tax
It is important to remember that after a taxpayer has paid their advance tax and if there are any tax dues that need to be paid after the end of the financial year, they have to be paid as self-assessment tax.
A taxpayer, before filing his or her income tax return, is required to pay the self-assessment tax. Employers deduct TDS from salary. However, if additional tax remains payable after considering salary TDS, taxpayers must calculate and pay self-assessment tax themselves before filing ITR. If a taxpayer is liable to pay self-assessment tax, they will not be able to file their income tax returns unless they have paid the self-assessment tax. The self-assessment tax needs to be evaluated by the taxpayer on their terms, and then it has to be settled with the government. There are various ways a taxpayer can settle their self-assessment tax, which can be done both offline and online. Both processes have to be carefully followed, as any discrepancy can lead to significant issues in the return form and processing of the return.
Computing self-assessment tax
Self-assessment tax is to be calculated by subtracting all available tax credits, that is, advance tax, TDS, MAT/AMT, TCS, credit, and relief existing under section 87A/90/90A/91. The taxpayer is required to give self-assessment tax along with the interest and penalty any it has been levied. There is an additional fee owed from the Assessment Year 2018-19 for the delay in filing the ITR. A late filing payment of Rs 5,000 shall be imposed if the return is filed. A late filing payment of Rs 5,000 shall be imposed if the return is filed after the ITR filing due date 31st July or 31st August (as applicable). The late filing fees will be Rs 1,000 for taxpayers whose taxable revenue is up to Rs 5 lakh, and for taxable income exceeding 5 lakhs penalty is levied for the amount of Rs. 5000. The tax, along with interest and Penalty, needs to be paid before submitting the return, and the particulars of the tax payment are mandatory to be shown in the income tax return form.
For computing the self-assessment tax, a taxpayer needs to follow the steps as listed below closely

| Minus - MAT Credit under Section 115JAA | —— |
| Minus - TDS/TCS | —— |
| Minus - Advance Tax | —— |
| Tax to be paid | Total Amount |
Partly paid Self-Assessment Tax
In case the tax paid is not in full, the amount that a taxpayer pays should first be adjusted towards the interest payable and the balance towards tax. Let us understand this with the help of an example:
| Income Tax | 2,00,000 |
| (Add) Interest under Section 234A/B/C | 30,000 |
| (Less) TDS and Advance Tax | 50,000 |
| Self-Assessment Tax to be paid under Section 140A | 1,80,000 |
| Amount paid as Self-Assessment Tax | 70,000 |

Also, it is simpler to track and retain a document of the payment made by the taxpayer. If the taxpayer wants to make the payment via cheque, name the cheque courtesy of the “Income Tax Department.”

Challan status inquiry
As soon as the taxpayer has made the tax return, they can verify its state on the TIN-NSDL portal. To verify the state, heed to the listed actions:
- On the TIN-NSDL portal, tick on 'Services' and choose 'Challan Status Inquiry.'
- The taxpayer will be taken to a different page. On that new tab, below the 'For Taxpayers' title, select 'CIN-based view.' Identify yourself as a taxpayer, and the taxpayer can utilize only CIN-based aspects to perceive the state of the tax returned by them.
- The taxpayer will be compelled to communicate a few articles from the challan slip, i.e., the BSR key of the collecting office, challan tender time, and challan serial number. Insert the captcha cryptogram and agree on the show.
Considering it takes 5-10 days to refresh the status, it will display any of the three outcomes:
- No records: This indicates that the bank has yet to transfer the tax refund to the income tax office.
- Price Matched: This implies that the bank has transferred the tax refund to the income tax office, but the office has yet to confirm it.
- Accepted by TIN: It implies that the income tax office has obtained the tax payment. It will dispense the date on which the payment was collected.
How to re-print challan 280
In case the taxpayer has lost their challan slip, they can download the identical by logging in to their net banking account (if the refund was made by net banking). To download the identical, the taxpayer has to log in to their account via net banking, go to the tax center, and agree on a 'reprint challan' to do the corresponding. On the other hand, if the taxpayer has made the fee offline, either via cash/cheque or online by a debit card, then they are expected to communicate the same to the bank's branch.
Form 26AS & Self-assessment Tax
Usually, each actuality (individual or company) that has subtracted taxes must attribute that value to the administration via banks. Banks need to upload these TDS features into the Tax Information Network (TIN) central system. The deductors, side-by-side, would record quarterly reports to TIN, implementing quarterly TDS items. Based on specific circumstances, the TIN central system coordinates information linked to tax payment before transforming into a comprehensive record for the particular PAN. This is Form 26AS.
Mainly, the Form 26AS report presents an amalgamated picture of the total revenue received by the taxpayer as a deductee from multiple sources. It also involves the TDS/ TCS sum that has been subtracted from their Gross receipts and recognized by the Income Tax Department.
Difference between self-assessment tax and advance tax
SAT and Advance Tax are both paid to the Income Tax Department. While both tax liabilities are remitted to the government of India, they are different in nature and application.
| Feature | Self-Assessment Tax | Advance Tax |
|---|---|---|
| Timing | Paid after the financial year ends but before filing the income tax return | Paid in installments during the financial year based on estimated income |
| Basis for Calculation | Actual income earned in the previous financial year | Estimated income for the current financial year |
| Purpose | To settle any remaining tax liability after considering TDS and advance tax | To pay tax liability throughout the year and avoid interest charges on late payments |
| Due Date | No specific due date, but generally paid before filing the return (usually July-September) | Specific due dates throughout the financial year (typically 15th June, 15th September, 15th December, and 31st March) |
| Penalty | Interest is charged on any unpaid tax | Interest and penalty are charged on any shortfall in advance tax payment |
Reasons for mismatches between the TDS statement and Form 26AS
There are numerous circumstances where the TDS Credit in the TDS statement and, accordingly, in Form 16 or 16A may diverge from what is accessible in Form 26AS. The most frequent causes for such discrepancy are listed here:
- Non-fulfilment of the deductor to pledge TDS on time,
- The incorrect value contained in the TDS return,
- Incorrect PAN cited in the TDS return,
- A blunder in the CIN (Challan identification number),
- The deductor’s PAN/TAN was improperly incorporated,
- Error in the preferred taxable year
- Imperfections in the TDS return
- Unfinished details of the taxpayer in the TDS return
- Mismatch in the TDS cited and the original TDS subtracted
Correcting mismatches: More frequently than not, such mismatches can be associated with the incorrect information furnished in the TDS return. So, kindly request the employer/deductor to file an amended TDS return after performing the essential changes.
The Income Tax department permits the taxpayer to notify the idea of a mismatch on the website in response to a notice posted by the department.
Outcomes of a mismatch: Automated ITR processing of income tax returns has made it more straightforward to distinguish matches in Form 26AS and TDS reports. The income tax website includes links that would give admittance to 26AS, enabling the taxpayer to check and cross-check the features. Therefore, you must make sure that TDS details in TDS reports and Form 26AS match to circumvent the subsequent outcomes:
- With the pre-fill convenience made possible in the tax portal and services, all the information accessible in the 26AS is instinctively being filled in the ITR. In the case of mismatches, the value pre-filled will mismatch with the original computations.
- The elimination of records by the deductor will appear if the taxpayer is not receiving credit for taxes subtracted, and this could end up in a tax-owed situation.
- There will be a setback in preparing the income tax return of that particular taxpayer.
- Declaration of payment of extra fee subtracted will linger further than required.
