GST TDS/TCS RECONCILIATION WORKING PAPER — GOVERNMENT CONTRACTS & E-COMMERCE

Entity: ___ · GSTIN: ___ · Financial year ended: ___

Purpose: reconcile GST credit arising from two DISTINCT mechanisms — Section 51 TDS (deducted by specified government departments, local authorities, and PSUs on contracts exceeding the notified value threshold, currently ₹2.5 lakh per contract — verify for the year) and Section 52 TCS (collected by e-commerce operators on the net value of taxable supplies made through them) — against the credit actually recorded in books.

TDS credit (Section 51) and TCS credit (Section 52) both flow into the electronic cash ledger of the deductee/supplier, not the credit ledger, and both require the counterparty to file their own return (GSTR-7 for TDS deductors, GSTR-8 for e-commerce operators collecting TCS) before the credit reflects and can be claimed — the same "counterparty must file first" logic that drives ITC-2A/2B mismatches applies here too.

Common questions

FAQs.

What is the difference between Section 51 TDS and Section 52 TCS under GST?
Section 51 TDS is deducted by specified government departments, local authorities, and government-controlled entities/PSUs when paying a supplier under a contract above the notified value threshold. Section 52 TCS is collected by e-commerce operators on the net value of taxable supplies made THROUGH their platform by other suppliers — a completely different trigger (a platform transaction, not a government payment) and a different filer (GSTR-8 for the operator, versus GSTR-7 for the government deductor).
Does GST TDS/TCS credit reduce the amount payable, or does it need to be separately claimed?
It flows into the deductee's/supplier's electronic CASH ledger (not the credit ledger) once the deductor/operator files their GSTR-7/GSTR-8 return, and must then be accepted on the GST portal by the recipient to become usable for paying output tax liability in cash — an amount deducted/collected but not yet reflected (because the counterparty hasn't filed) cannot be used until it does.
Is GST TDS the same as Income-tax TDS on the same contract?
No — they are entirely separate deductions under separate statutes, both potentially applicable to the same payment. Income-tax TDS (under the Income-tax Act) is deducted on the payment/income and reduces the recipient's income-tax liability; GST TDS (under Section 51 of the CGST Act) is deducted on the taxable value of the supply and credits the recipient's GST cash ledger — a contract can attract both simultaneously, each governed by its own threshold and rate.
