For salaried employees in India, Tax Deducted at Source (TDS) is one of the most common deductions seen on a monthly payslip. The legal provision governing TDS on salary is Section 192 of the Income Tax Act. It places the responsibility on employers to calculate the employee’s estimated annual tax liability and deduct the appropriate amount before paying the salary.
Understanding how this provision works can help employees interpret their payslips, avoid tax surprises, and identify discrepancies before filing their income tax return.
What Does Section 192 Mean?

Section 192 applies specifically to income classified as salary. Unlike provisions where TDS is deducted at a predetermined percentage, salary TDS is generally calculated according to the applicable income-tax slab rates.
The employer estimates the employee’s taxable income for the financial year, considers eligible exemptions, deductions, rebates and other declared income, and then determines the expected tax liability. The resulting amount is normally spread across the remaining salary payments.
When Is Salary TDS Deducted?
TDS under Section 192 is deducted when salary is actually paid. Therefore, the amount shown as TDS may not remain identical every month.
For instance, receiving bonuses or increments can enhance the expected annual income. As a result, payroll can recompute the annual tax payable and modify the deductions in the remaining months. This explains why TDS can occasionally rise dramatically in a month.
Salary elements taken into account
When calculating TDS, companies usually take into account the taxable components of pay like:
Basic salary and taxable allowances
Bonus and incentive payments
Commission paid
Taxable benefits
Other taxable salary components
Employers might take into account the exemptions and deductions according to the tax plans of the workers in addition to the above-mentioned components.
Deductions allowed will play an important role when computing the taxable amount. However, laws can change, and employees should check the regulations in the financial year.
Old vs new tax regulations.
Employees will have to consider the benefits of both regimes since both tax regimes have their positive sides. The old tax regime is more beneficial in terms of deductions and exemptions available; the new tax system has simpler rates.
What Happens When You Change Jobs?

Changing employers during a financial year can complicate TDS calculations. If the new employer does not know about salary already received from the previous employer, the overall tax calculation may not accurately reflect the employee’s annual income.
Employees should therefore provide relevant previous-employment salary and TDS details to the new employer when required. According to section 192(2B), there are specific other types of income that could possibly be taken into consideration along with tax in relation to the taxpayer by the employer.
There are advances against salary as well as salary arrears. Though they are to be reported in the same financial year of payment, they are actually accrued in the previous year. For certain specific situations, section 89 relief can be availed in order to compensate for the extra taxes involved in receiving such earlier year income. Employees who claim section 89 relief must perform the required compliance act and fill in the Form 10E if applicable.
Employers have to deposit deducted TDS promptly and present TDS through forms at the end of the financial year. At the end of the financial year, Form 16 is issued to employees containing complete information on salary and deductions. Employees must ensure that the information provided in Form 16 is consistent with the information contained in payslips.
