Introduction
Every month when a salaried employee gets their salary, a certain amount is already deducted before the money reaches their bank account. Ever wondered what that deduction is? That’s TDS — Tax Deducted at Source.
Similarly, when a seller sells certain goods like scrap or timber, the buyer deducts a small tax before paying. That’s TCS — Tax Collected at Source.
Both TDS and TCS are methods used by the Indian government to collect income tax in advance — before you file your return at the end of the year. They ensure tax reaches the government throughout the year and reduce tax evasion.
| Simple rule: TDS = Tax deducted by the PAYER before making payment. TCS = Tax collected by the SELLER from the BUYER at the time of sale. |
What is TDS? (Tax Deducted at Source)
TDS is a mechanism where the person making a payment deducts a certain percentage of tax before paying the receiver. The deducted amount is deposited directly with the government on behalf of the receiver.
Real Life Example of TDS:
Ramesh is a freelancer. He does a ₹1,00,000 project for ABC Company. Instead of paying ₹1,00,000, ABC Company deducts 10% TDS = ₹10,000 and pays Ramesh only ₹90,000. The ₹10,000 goes directly to the government as advance tax on Ramesh’s behalf.
| Who Deducts TDS? | On What Payment? | TDS Rate |
| Employer | Salary paid to employee | As per income tax slab |
| Company / Firm | Professional fees / consultancy | 10% |
| Bank | Interest on Fixed Deposit (>₹40,000) | 10% |
| Company / Individual | Rent (>₹50,000/month) | 2% (individual), 10% (company) |
| Buyer of property | Purchase of immovable property (>₹50 lakhs) | 1% |
| Company | Commission or brokerage | 5% |
| Company | Winning from lottery / game shows | 30% |
What is TCS? (Tax Collected at Source)
TCS is collected by the SELLER from the BUYER at the time of sale of specified goods or services. The seller then deposits this collected tax with the government.
Real Life Example of TCS:
Suresh buys scrap metal worth ₹5,00,000 from a scrap dealer. The scrap dealer collects 1% TCS = ₹5,000 extra from Suresh and deposits it with the government. Suresh pays ₹5,05,000 total.
| Goods / Transaction | TCS Rate |
| Scrap (waste material) | 1% |
| Timber obtained under a forest lease | 2.5% |
| Timber obtained by any other mode | 2.5% |
| Tendu leaves | 5% |
| Forest produce (other than timber/tendu leaves) | 2.5% |
| Alcoholic liquor for human consumption | 1% |
| Motor vehicles (value > ₹10 lakhs) | 1% |
| Foreign remittance under LRS (>₹7 lakhs) | 5% (20% without PAN) |
| Sale of goods (turnover > ₹10 crore — seller) | 0.1% |
| Overseas tour packages | 5% |

TDS on Salary — Detailed Explanation
TDS on salary is governed by Section 192 of the Income Tax Act. Your employer deducts TDS from your salary every month based on your estimated annual income and the applicable income tax slab.
How is Salary TDS Calculated?
- Employer estimates your total annual salary at the start of the year
- They subtract all eligible deductions (HRA, 80C, 80D, Standard Deduction ₹75,000 etc.)
- They calculate income tax on the net taxable income as per the slab rates
- This total annual tax is divided by 12 months
- Each month, that amount is deducted from your salary as TDS
Example: Salary TDS Calculation
| Particulars | Amount |
| Annual CTC (Gross Salary) | ₹8,00,000 |
| Less: Standard Deduction | ₹75,000 |
| Less: HRA Exemption | ₹60,000 |
| Less: 80C Investments (PF, ELSS etc.) | ₹1,50,000 |
| Net Taxable Income | ₹5,15,000 |
| Income Tax (New Regime 2025-26) | ₹13,000 approx |
| Monthly TDS (₹13,000 ÷ 12) | ₹1,083/month |
Form 16 — TDS Certificate for Salary
Form 16 is a TDS certificate issued by your employer every year (by June 15) showing how much salary was paid to you and how much TDS was deducted.
Form 16 has Two Parts:
| Part | Contains | Issued by |
| Part A | Employer details, employee details, PAN, TAN, total TDS deposited quarter-wise | Downloaded from TRACES portal by employer |
| Part B | Detailed salary breakup — HRA, allowances, perquisites, deductions (80C, 80D etc.), net taxable income | Prepared by employer |
Why is Form 16 Important?
- It is the primary document for filing your Income Tax Return (ITR)
- Banks and financial institutions ask for Form 16 for loan approvals
- It serves as proof of income and TDS payment
- If TDS deducted > actual tax liability → you get a refund using Form 16 data
| Tip: Even if your employer does not deduct TDS (income below taxable limit), you should still get Form 16 Part B as a salary statement for your records. |
Form 26AS — Your Tax Passbook
Form 26AS is a consolidated tax statement available on the Income Tax portal. It shows ALL tax deducted/collected on your behalf by various deductors — employer, bank, buyer etc.
- TDS by employer (salary)
- TDS by bank (FD interest)
- TCS collected from you (vehicle purchase, foreign remittance etc.)
- Advance tax paid by you
- Self-assessment tax paid
