What is TDS (Tax Deducted at Source)?
Tax Deducted at Source, universally known in India by its acronym TDS, is a mechanism built into the Indian Income Tax Act of 1961 through which tax is collected at the very point where income is generated. Rather than waiting for a taxpayer to declare income at the end of the financial year and pay the tax due, the government requires certain specified persons — called deductors — to deduct a percentage of the payment they are making and deposit that amount directly with the central government. The recipient of the payment — called the deductee — effectively receives the net amount after the deduction and later claims the TDS as a credit against the final tax assessed on their return.
The logic behind TDS is elegant: it ensures a steady inflow of tax revenue into the government treasury throughout the year rather than in a single annual lump sum, and it reduces the scope for tax evasion because the liability is captured before the money reaches the taxpayer’s hands. The system has been progressively expanded since independence to cover salaries, interest income, contract payments, professional fees, rent, dividends, and many other categories of payment.
You can use the TDS Calculator to instantly compute how much TDS applies to any payment — it covers 14 sections, applies the correct rate for FY 2024-25, and factors in the PAN rule and cess.
Why TDS Exists: The Advance Tax Collection Philosophy
Before TDS, the government relied on taxpayers to voluntarily compute and pay advance tax in instalments during the year. While that system still exists for certain categories of income, it depends on self-reporting and projections that are inherently uncertain. TDS eliminates the uncertainty for categories of income where a single identifiable payer is making a payment to an identifiable recipient. The payer is required by law to become a tax collection agent, withholding the government’s share before handing over the rest.
This mechanism also widens the tax base. When an individual who might otherwise not file a return receives income that has already had TDS deducted, their transaction is already captured in the government’s data system. The Income Tax Department can cross-reference the TDS returns filed by the deductor against the ITRs filed by the deductee, making it far harder for income to slip through the net.
Who is Liable to Deduct TDS?
Liability to deduct TDS falls on any person making a payment that falls under a TDS section, provided that person qualifies as a deductor under the Act. For most sections, the deductor must be one of the following: a company (Indian or foreign), a firm including an LLP, a Hindu Undivided Family (HUF), an individual or HUF whose accounts are subject to tax audit under Section 44AB, or a trust or co-operative society in specific circumstances.
Individuals and HUFs whose accounts are not subject to tax audit are generally exempt from the obligation to deduct TDS on most payments — a practical relief that prevents every private individual from being burdened with TDS compliance when paying a plumber or a freelancer. However, this exemption does not extend to rent payments under Section 194-IB (where individuals and HUFs paying rent above a threshold have a separate simplified obligation) or to certain property transactions.
Deductors must obtain a Tax Deduction and Collection Account Number (TAN) before they can deduct and deposit TDS. Without a TAN, they cannot file TDS returns or issue TDS certificates to the deductees.
Key TDS Sections for FY 2024-25
The Income Tax Act contains dozens of TDS sections. The most commonly applicable ones are described below with their current rates.
Section 192 — Salaries. This is the section under which employers deduct TDS from employee salaries. There is no fixed rate; instead, the employer is required to estimate the employee’s total income for the year, apply the applicable slab rates (including surcharge and cess), and deduct that tax in equal monthly instalments. This makes Section 192 unique among TDS sections because it accounts for the full tax computation rather than applying a flat percentage.
Section 194 — Dividends. Dividends paid by domestic companies to resident individual shareholders attract TDS at 10% if the dividend exceeds Rs. 5,000 in a financial year from a single company. The abolition of Dividend Distribution Tax in 2020 made dividends taxable in the hands of recipients, and Section 194 was accordingly activated.
Section 194A — Interest on deposits and loans. Banks, co-operative societies, and post offices deduct TDS at 10% on interest paid to residents when the interest exceeds Rs. 40,000 per year (Rs. 50,000 for senior citizens). For other interest payments such as inter-company loans, the threshold is Rs. 5,000.
Section 194B — Lottery, crossword puzzles, and card games. Winnings from lotteries, game shows, and similar activities attract TDS at 30% (plus surcharge and cess) on amounts exceeding Rs. 10,000.
Section 194C — Payments to contractors and sub-contractors. Contract payments attract TDS at 1% for individuals and HUFs, and 2% for others. The threshold is Rs. 30,000 per single payment or Rs. 1,00,000 in aggregate during the year to a single contractor.
Section 194D — Insurance commission. Commission paid to domestic insurance agents is subject to TDS at 5% where the aggregate commission exceeds Rs. 15,000 during the year.
Section 194H — Commission or brokerage. Commission or brokerage payments (excluding insurance commission under 194D and securities transactions) attract TDS at 5% when the aggregate exceeds Rs. 15,000 per year.
Section 194I — Rent. Rent paid to residents for use of land, building, plant, machinery, equipment, furniture, or fittings is subject to TDS. The rate is 10% for land and building, and 2% for plant, machinery, or equipment. The threshold is Rs. 2,40,000 per year.
Section 194J — Professional and technical fees. Fees for professional services (doctors, lawyers, architects, accountants, engineers) and technical services attract TDS at 10%. Call centre fees attract a reduced rate of 2%. The threshold is Rs. 30,000 per year per category.
Section 194N — Cash withdrawals. TDS applies on cash withdrawals from banks, co-operative banks, and post offices exceeding Rs. 1 crore in a year (for persons who have filed ITR in any of the last three years). For those who have not filed ITR, the threshold is Rs. 20 lakh. The rate is 2% above Rs. 1 crore (or Rs. 20 lakh for non-filers) and 5% above Rs. 1 crore for non-filers.
The 20% Rule for PAN Not Provided
Section 206AA of the Income Tax Act creates a powerful incentive for deductees to provide their PAN to the deductor. If a deductee fails to furnish a valid PAN, the deductor is required to deduct TDS at the higher of the following: the rate specified in the relevant section, the rate in force (as per Finance Act), or 20%. In practice, this almost always means a minimum 20% deduction for any person who does not share their PAN, making non-furnishing of PAN significantly expensive for recipients.
This provision was introduced specifically to improve PAN penetration and ensure that income can be traced back to identified taxpayers. From the government’s perspective, a payment made without a PAN is essentially a payment into an information black hole. The punitive 20% rate pushes deductees to link their income to their PAN and, by extension, to their ITR.
How Threshold Limits Work
Most TDS sections specify a monetary threshold below which no TDS is required even if the payment would otherwise attract it. These thresholds are designed to reduce the compliance burden for small, routine transactions. For example, a contractor paid Rs. 25,000 for a one-time job need not have TDS deducted under Section 194C because the amount falls below the Rs. 30,000 single-payment threshold. However, if the same contractor receives multiple payments from the same person that aggregate to more than Rs. 1,00,000 during the year, TDS becomes applicable on the entire cumulative amount from the point the threshold is crossed.
It is important to understand that crossing the threshold triggers TDS on the full amount paid, not just on the excess over the threshold. Deductors must therefore maintain running totals of payments made to each deductee during the year and begin deducting as soon as the threshold is breached.
TDS vs Advance Tax vs Self-Assessment Tax
These three concepts are all mechanisms for collecting income tax, but they differ in who is responsible, when payment occurs, and on what basis it is calculated.
TDS is deducted by the payer on behalf of the recipient, based on the specific payment being made. It happens automatically at the source and the recipient has no direct control over when or how much is deducted. Advance tax, by contrast, is paid by the taxpayer themselves in four instalments during the year (15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15) based on their estimated annual income. Self-assessment tax is what remains — the difference between the final tax liability computed at the time of filing the ITR and the sum of TDS credits and advance tax already paid. All three flow into the same tax liability and appear as credits in Form 26AS.
How TDS is Deposited: Challan 281
Once TDS is deducted, the deductor must deposit it with the government within specified due dates — generally the 7th of the month following the month of deduction, with the exception of March deductions which must be deposited by April 30. The deposit is made using Challan 281, which is the designated payment instrument for TDS and TCS. Payment can be made online through the Income Tax e-filing portal (tax.gov.in) or through authorised bank branches. Upon successful payment, the deductor receives a challan receipt with a BSR code and challan serial number, both of which are used when filing the TDS return to reconcile the deposit with the TDS return data.
Late deposit attracts interest at 1.5% per month (or part of a month) from the date of deduction to the date of deposit.
How to File TDS Returns
Deductors must file quarterly TDS returns to report the details of all TDS deductions made during the quarter. The return forms are:
Form 24Q for TDS on salaries (Section 192), Form 26Q for TDS on all payments to residents other than salary, Form 27Q for TDS on payments to non-residents other than salary, and Form 27EQ for TCS returns.
Returns are filed quarterly — for Q1 (April to June) by July 31, Q2 (July to September) by October 31, Q3 (October to December) by January 31, and Q4 (January to March) by May 31. Returns are submitted electronically through the TRACES portal (tin.tin.nsdl.com or tdscpc.gov.in). After processing, the deductor can download and issue Form 16 (for salary TDS) or Form 16A (for non-salary TDS) to the deductees, who use these as certificates of TDS deducted for their own ITR filings.
