TDS (Tax Deducted at Source) is a system in India where tax is deducted at the point of income generation — by the payer before the receiver gets payment. It ensures timely tax collection, reduces evasion, and spreads the tax burden throughout the year.
💡 What is TDS?
TDS stands for Tax Deducted at Source — a system under the Income Tax Act, 1961.
It ensures that tax is collected from the source of income itself, whether it’s salary, rent, commission, or professional payment. Instead of paying tax at year-end, tax is deducted throughout the year when income is credited or paid.
In simple terms:
Whenever someone makes a payment (like salary or commission), a small portion of that amount is deducted and paid directly to the government as tax.
This concept ensures steady government revenue and reduces the chances of tax evasion.

🎯 Purpose and Importance of TDS
TDS serves multiple objectives that benefit both the government and taxpayers:
1. Ensures Timely Tax Collection
Instead of waiting for annual returns, TDS provides continuous inflow of revenue to the government.
2. Prevents Tax Evasion
As deductions happen at the payment stage, there’s less room for manipulation.
3. Reduces Burden on Taxpayers
Taxpayers don’t need to pay a large lump sum at the end of the year.
4. Promotes Transparency
Every TDS deduction reflects in Form 26AS, ensuring clear records.
5. Encourages Compliance
Since deductions are automated, individuals and companies stay compliant with the tax laws.
⚙️ How TDS Works – Step-by-Step Process
Here’s how TDS deduction operates from start to finish:
- Payment Identification:
The payer identifies if the payment (salary, rent, etc.) attracts TDS. - Check Threshold Limit:
Confirm whether the payment amount crosses the exemption limit. - Deduct Applicable Tax Rate:
Apply the prescribed rate as per Section 192–194 of the Income Tax Act. - Deposit with the Government:
Deposit deducted TDS within the due date using Challan ITNS 281. - File TDS Return:
Submit quarterly returns (Form 24Q, 26Q, etc.) detailing deductions. - Issue TDS Certificates:
Provide Form 16 (salary) or Form 16A (other income) to the recipient.
📘 TDS Deduction Example (2025)
Let’s understand with a real example:
| Scenario | Description |
|---|---|
| Employee’s Annual Salary | ₹9,00,000 |
| Applicable TDS Slab | 10% |
| Monthly TDS Deducted | ₹7,500 |
| Annual TDS | ₹90,000 |
| Deposited to Government | Monthly by employer |
| Reflected in Form 26AS | Yes |
Thus, instead of paying ₹90,000 at once, tax is deducted evenly across 12 months — making it easier to manage.
