Tax Deducted at Source (TDS) is a system in which tax is collected from income at the point it is paid, rather than later when the recipient files a return. On salary, the employer estimates the employee's annual income tax and deducts it in installments from each month's pay, then deposits it with the government on the employee's behalf. It is a core payroll compliance duty for any company employing people in India.
How does TDS on salary work?
TDS on salary spreads an employee's expected annual tax across the year so that it is paid gradually rather than in one lump sum. The employer drives the whole process.
- Estimate annual tax: the employer projects the employee's yearly income, deductions, and chosen tax regime to estimate total tax.
- Deduct monthly: that estimated tax is divided across the year and withheld from each month's salary.
- Deposit with the government: the deducted tax is paid to the tax authorities, generally by the 7th of the following month.
- Report and certify: the employer files quarterly TDS returns and issues an annual certificate (Form 16) to the employee.
What affects how much TDS is deducted?
The amount withheld is not fixed; it depends on the employee's overall tax position, which the employer must estimate accurately to avoid over or under deduction.
- Tax regime: the employee's choice between the old and new tax regime changes the rates and available deductions.
- Declared investments: deductions the employee declares can reduce taxable income under the old regime.
- Allowances and exemptions: components such as house rent allowance can lower the taxable amount.
- Other income: income the employee reports to the employer can be factored into the calculation.
Key TDS deadlines for employers
TDS comes with a calendar of obligations, and missing a deadline attracts interest, fees, and penalties. The main recurring duties are summarized below.
| Obligation | Typical timing |
|---|---|
| Deposit TDS | By the 7th of the following month |
| File quarterly return | After each quarter |
| Issue Form 16 | Annually, after the financial year |
