For a large number of taxpayers, especially those who switched jobs during the year, the answer often lies in a simple but critical filing mistake. It doesn’t just delay refunds; in some cases, it can even trigger a tax notice.
The issue begins with a misunderstanding of how multiple employers calculate tax. While you may receive two Form 16s—one from your previous employer and one from your current one—you are required to file a single consolidated return for the entire financial year. Each employer deducts tax only on the salary they pay and typically has no visibility into your total annual income unless you disclose it.
This creates an information gap. Both employers may calculate tax assuming your income falls within a lower slab. But when your total earnings are combined, you could fall into a higher tax bracket. The result is under-deduction of tax, which only becomes apparent when you file your return. The tax department’s systems assess your income in totality, not in parts, and any shortfall is immediately flagged.
One of the most common and costly errors that stems from this situation is the double claim of the standard deduction. Each Form 16 may reflect this deduction, usually ₹50,000, leading many taxpayers to assume they can claim it twice. This is incorrect. The standard deduction is allowed once per taxpayer for the entire financial year, not per employer. Claiming it twice artificially reduces taxable income and is quickly identified by automated systems. This single mistake is often enough to push a return into scrutiny, delaying refunds significantly.
Filing correctly requires a shift in approach—from relying on individual Form 16s to building a consolidated financial picture.
The first step is to combine your total salary income. If your previous employer paid ₹6 lakh and your current employer paid ₹8 lakh, your taxable salary is ₹14 lakh. This combined figure forms the basis of your tax computation. Treating each Form 16 separately is where most errors begin.
The next step is to apply deductions carefully and correctly. The standard deduction should be claimed only once against your total salary. The same principle applies to exemptions such as House Rent Allowance. While the calculation itself may vary depending on rent paid and salary structure, the exemption must be determined for the entire year, not duplicated across employers.
Tax credit verification is equally critical. Add the total tax deducted by both employers and cross-check it with your Form 26AS and Annual Information Statement (AIS). These documents represent the tax department’s official record of taxes credited to your PAN. If there is a mismatch, the figures reflected in these statements will determine the credit you can claim.
Once income and TDS are consolidated, the final step is to compute your total tax liability on the combined income. In many cases, taxpayers discover a shortfall because earlier TDS was calculated on partial income. This gap must be paid as self-assessment tax before filing the return. Ignoring this step leads to demand notices, interest penalties, and further delays in refund processing.
Even when calculations are correct, operational lapses can still hold up refunds. One common issue is failure to pre-validate the bank account on the income tax portal. Refunds are processed only to accounts that are validated and linked to your PAN. Another frequent oversight is incomplete e-verification. If the return is not verified within the stipulated time, it is treated as invalid, and processing does not begin.
In some cases, refunds are adjusted against past tax demands. If there is an outstanding liability from a previous year, the department can offset it against your current refund after notifying you. If left unaddressed, this adjustment happens automatically, reducing or eliminating the expected refund.
The broader lesson is clear. Switching jobs introduces complexity into tax filing, and relying blindly on Form 16s is not enough. You must take ownership of your financial data—combine income, apply deductions correctly, verify tax credits, and settle any shortfall before filing.
Handled properly, this process ensures smooth filing and timely refunds. Overlooked, it can lead to unnecessary stress, delays, and avoidable notices. In a system driven by data matching and automation, accuracy is not just important—it is essential.
