TDS Calculator

A simple salary TDS estimate. Use it to understand the annual tax that may need to be spread across payroll, not as a substitute for your employer's payroll calculation.

Salary TDS vs Final Income Tax

TDS is a collection mechanism, not a separate tax. Your final liability is determined when all relevant income, deductions, exemptions, special-rate income, rebate, surcharge and cess rules are considered.

Why Your TDS Can Change During the Year

Employers can update payroll calculations when you submit investment declarations, change jobs, receive a bonus, revise salary, or provide additional income information. A change in tax regime selection can also change the monthly deduction.

What Is TDS?

Tax Deducted at Source (TDS) is a mechanism through which tax is collected when certain payments are made. For salary, the employer estimates the employee’s annual taxable income and deducts tax from salary during the year. TDS is then credited against the employee’s final income-tax liability.

TDS is therefore not an extra tax. It is generally a method of collecting tax in advance. When you file your ITR, the tax already deducted and available as credit is considered against the final tax calculation.

How Salary TDS Is Estimated

  1. Employer estimates annual salary and other information provided for payroll.
  2. Eligible exemptions and deductions are considered according to the selected tax regime and applicable rules.
  3. Tax is calculated using the relevant rates and rebate provisions.
  4. The expected annual tax is spread over the remaining salary payments.
  5. TDS deducted is reported and can be reflected in Form 26AS/AIS.

Why Monthly TDS Can Change

Salary TDS can change after a bonus, salary hike, arrears, a revised declaration, a change in tax regime or an adjustment made by the payroll team. The final months of the financial year can sometimes have higher TDS if the employer needs to recover a tax shortfall.

TDS vs Final Income Tax

The TDS shown on your salary slip is not necessarily your final tax. Your ITR considers all income sources and eligible claims. If too much tax was deducted, you may receive a refund after processing. If too little was deducted, additional tax may be payable.

Form 16, Form 26AS and AIS

Form 16 is a key salary-TDS certificate issued by the employer. Form 26AS contains tax-credit information associated with your PAN, while the Annual Information Statement (AIS) can contain broader financial information reported by various entities. Before filing, reconcile these records with your salary slips, bank records and other income.

Example: Why Annual TDS Is More Useful Than a Flat Monthly Percentage

Suppose an employee’s expected annual tax is ₹60,000. The employer does not necessarily deduct exactly ₹5,000 every month throughout the year. If the employee joins midway through the year, receives a bonus or submits deductions later, the remaining monthly TDS can be adjusted so that the annual estimate is recovered.

TDS on Other Payments

TDS also applies to various non-salary payments under separate sections and thresholds. The rate and threshold depend on the nature of the payment, the recipient and the applicable law. A salary TDS calculator should not be used to estimate every kind of TDS transaction.

What to Do if TDS Is Wrong

First compare the salary slip with Form 16 and the tax-credit information available through the Income Tax portal. If the employer’s reported TDS is incorrect, contact the payroll or tax team and ask for the correction to be reported. Do not assume that an amount appearing on a salary slip automatically means the same credit is available in your tax records.
