GST TDS Under Section 51 — Complete Guide

Tax Deducted at Source (TDS) under GST was introduced under Section 51 of the CGST Act, 2017. Certain categories of persons are required to deduct TDS at 2% (1% CGST + 1% SGST/UTGST for intra-state, or 2% IGST for inter-state) when making payments for taxable supplies exceeding ₹2,50,000.

Who Must Deduct TDS Under GST?

  • A department or establishment of the Central or State Government
  • Local authority
  • Governmental agencies
  • Persons or categories notified by the Government on the Council's recommendation
  • An authority, board, or body set up by Parliament, State Legislature, or Government with 51%+ equity or control by Government
  • Society established by Central or State Government or a local authority under the Societies Registration Act
  • Public Sector Undertakings

TDS Rate and Threshold

  • Rate: 2% of the payment (1% CGST + 1% SGST for intra-state; 2% IGST for inter-state)
  • Threshold: ₹2,50,000 per contract (excluding GST)
  • TDS is deducted from the value of supply, not on the GST component
  • Individual payments below ₹2.5 lakh still attract TDS if the total contract exceeds the threshold

Filing Requirements

  • GSTR-7: Monthly return by the deductor — due by 10th of the following month
  • GSTR-7A: TDS certificate generated automatically and available to the deductee
  • Late filing penalty: ₹100/day under CGST + ₹100/day under SGST (max ₹5,000 each)

How Does the Supplier Claim TDS Credit?

Once the deductor files GSTR-7, the TDS amount reflects in the supplier's electronic cash ledger automatically. The supplier can use this credit to pay GST on outward supplies or claim a refund if TDS exceeds their liability.
