For most salaried employees, the financial year ends with a sense of relief. After all, tax has already been deducted from their salary every month through Tax Deducted at Source (TDS). Many believe that if TDS has been deducted by their employer, they have fulfilled all their tax obligations.
Unfortunately, this assumption can prove to be an expensive mistake.
Every year, thousands of taxpayers receive notices from the Income Tax Department despite having TDS deducted from their salary. The reason? TDS is only one part of your overall tax liability—it does not automatically mean that your taxes are fully paid or your Income Tax Return (ITR) will be accepted without discrepancies.
Understanding TDS: What It Really Means
Tax Deducted at Source (TDS) is a mechanism through which your employer deducts income tax from your monthly salary and deposits it with the government on your behalf. The amount deducted is generally based on the salary structure, declarations submitted by the employee, and estimated taxable income.
However, employers calculate TDS only on the information available to them. If that information is incomplete or inaccurate, the deducted tax may not match your actual tax liability.
The Hidden TDS Traps
1. Your Employer Doesn’t Know Your Complete Income
Your employer deducts TDS based only on the salary paid by the company. They may not know about:
- Interest earned on savings accounts or fixed deposits
- Rental income from property
- Capital gains from shares, mutual funds, or real estate
- Freelancing or consulting income
- Foreign income or overseas investments
- Dividend income
If these incomes are not disclosed while filing your ITR, the Income Tax Department can identify the mismatch through its Annual Information Statement (AIS) and other reporting systems.
2. Incorrect Investment Declarations
Many employees submit investment declarations at the beginning of the financial year to reduce TDS.
However, if the actual investments are not made or supporting documents are not submitted, the employer may recalculate TDS. In some cases, insufficient tax gets deducted, resulting in additional tax payable along with interest.
3. Choosing the Wrong Tax Regime
With the availability of both the Old Tax Regime and the New Tax Regime, many taxpayers simply accept the default option without evaluating which regime offers greater tax savings.
Selecting the wrong regime may increase your tax liability even if TDS has been deducted correctly according to your employer’s calculations.
4. Switching Jobs During the Financial Year
Changing employers is one of the most common reasons for tax mismatches.
If the new employer does not receive details of your previous salary and TDS deductions, they may calculate tax only on the current salary. This often leads to lower TDS deduction and a tax payment at the time of filing the ITR.
5. Form 26AS Doesn’t Match Your Salary Records
Sometimes employers deduct TDS but delay depositing it or make reporting errors.
Before filing your return, always compare:
- Form 16
- Form 26AS
- Annual Information Statement (AIS)
- Salary slips
Any mismatch should be resolved immediately with the employer.
6. Ignoring Other Taxable Income
Many taxpayers assume that small amounts such as savings account interest or dividend income need not be reported.
Even if tax has not been deducted on these incomes, they are generally taxable and must be disclosed while filing the Income Tax Return.
Why Income Tax Notices Are Increasing
The Income Tax Department now uses advanced technology and data analytics to verify taxpayer information.
It receives financial data from:
- Banks
- Mutual funds
- Stock brokers
- Property registrars
- Employers
- GST records
- Foreign financial reporting systems
This information is automatically reflected in the Annual Information Statement (AIS), making it easier for authorities to detect under-reporting of income.
How to Avoid the TDS Trap
Before filing your Income Tax Return, ensure that you:
- Verify Form 16 with Form 26AS and AIS.
- Report all sources of income, not just salary.
- Check whether the correct tax regime has been selected.
- Inform your employer about previous employment income.
- Pay Advance Tax or Self-Assessment Tax if required.
- Maintain supporting documents for deductions and exemptions claimed.
- File your return well before the due date to avoid last-minute errors.
The Bottom Line
TDS should never be treated as a confirmation that your tax responsibilities are complete. It is merely a method of collecting tax in advance based on available information.
Your final tax liability is determined only after considering all sources of income, eligible deductions, exemptions, and applicable tax provisions while filing your Income Tax Return.
A careful review before filing your ITR can help you avoid unnecessary tax demands, interest, penalties, and notices from the Income Tax Department. Spending a little extra time verifying your tax details today can save significant financial and legal complications in the future.
