Understanding TDS under GST

Tax Deducted at Source (TDS) under the Goods and Services Tax (GST) is fundamentally different from TDS under the Income Tax Act. Under Income Tax, TDS is deducted by almost all businesses on various services. However, under Section 51 of the CGST Act, TDS is a highly specific mechanism primarily aimed at tracking high-value government contracts to ensure contractors are paying their due taxes.

Our TDS under GST Calculator helps both government deductors and private contractors instantly determine the exact TDS amount to be withheld on an invoice, preventing costly compliance errors and ensuring the contractor receives the correct net payment.

Who Must Deduct TDS under GST?

If you are a private limited company, a partnership firm, or an individual business owner dealing with other private businesses, you do not deduct TDS under GST. The mandate to deduct TDS is strictly limited to the following entities:

  • A department or establishment of the Central Government or State Government.
  • Local authorities (Municipal Corporations, Panchayats, etc.).
  • Governmental agencies.
  • Public Sector Undertakings (PSUs).
  • Societies established by the Central Government, State Government, or a Local Authority.

The 2.5 Lakh Threshold Rule

The most common point of confusion is the ₹2,50,000 threshold. The law states that TDS is applicable if the total value of the contract exceeds ₹2.5 Lakhs.

This means you look at the Contract Value, not the individual Invoice Value. For example, if a Municipal Corporation awards a road repair contract worth ₹10,00,000 to a contractor, the threshold is crossed. Even if the contractor raises a small monthly running bill of just ₹50,000, the Municipal Corporation must deduct 2% TDS on that ₹50,000. Conversely, if a total contract is only for ₹2,00,000, no TDS is deducted, even if a single invoice is raised for the full ₹2,00,000 amount.

How is TDS Calculated? (The 2% Rule)

The rate of TDS under GST is universally fixed at 2%. However, the nature of the transaction determines how this 2% is split:

  • Intra-State (Same State): 1% CGST + 1% SGST.
  • Inter-State (Different States): 2% IGST.

CRITICAL RULE: The 2% is calculated strictly on the taxable value of the goods or services. It is never calculated on the GST amount. For instance, if the taxable value of a service is ₹1,00,000 and the 18% GST is ₹18,000, the total invoice is ₹1,18,000. The deductor will calculate the 2% TDS only on the ₹1,00,000 (which is ₹2,000). They will not calculate it on the ₹1,18,000.

What Happens to the Deducted TDS?

If you are the contractor whose money was deducted, do not worry—this money is not lost. The government department will deposit the deducted amount and file form GSTR-7 by the 10th of the following month.

Once they file GSTR-7, the deducted amount will automatically reflect on your GST portal under the TDS and TCS Credit Received tab. Once you accept it, this amount will flow directly into your Electronic Cash Ledger. You can then use this cash balance to pay your monthly GST liabilities, or even claim it as a refund if you don't have sufficient liabilities.
