Job Switchers Face Unexpected Tax Hit Amidst TDS Discrepancy

Salaried employees in India who switch jobs within a financial year are increasingly encountering unforeseen tax liabilities, even when both their former and current employers have diligently deducted Tax Deducted at Source (TDS). This phenomenon, highlighted by recent tax season observations, stems from a fundamental structural difference in how TDS is computed versus how final income tax obligations are determined. Employers typically calculate TDS based on the projected annual income from their specific organization, applying relevant tax slabs and deductions. However, when an employee transitions to a new company mid-year, the second employer often calculates TDS without full knowledge of the income earned from the previous employer. This results in a situation where both employers correctly deduct TDS on their respective portions of the income, but the combined TDS might fall short of the actual tax due on the aggregate annual income. The discrepancy arises because the final income tax liability is assessed on the total annual taxable income across all sources for the financial year. Each employer, operating independently, applies the full benefit of tax slabs and standard deductions (like the basic exemption limit) as if they were the sole income provider for the entire year. This effectively allows the employee to claim these benefits twice for different portions of their income, leading to an under-deduction of tax overall. To mitigate this issue, tax authorities have provided Form 12B. This form allows a new employer to receive details of income earned and tax deducted by the previous employer. By submitting Form 12B, the current employer can factor in the prior income and TDS when calculating subsequent deductions, ensuring a more accurate overall TDS deduction and reducing the likelihood of a significant tax demand at the time of filing annual returns.
