TDS and TCS under GST (Sections 51 and 52) for CA Intermediate

Understand TDS and TCS under GST

Key rules to remember

TDS applicability (section 51)

Deduct only if: deductor is a specified person AND contract value (excluding GST) > ₹2,50,000

Test the whole contract value, not each payment. Exactly ₹2,50,000 is not enough; it must exceed it.

TDS rate

2% = 1% CGST + 1% SGST (intra-State) or 2% IGST (inter-State)

Charged on the payment value excluding GST shown on the invoice.

TDS amount

TDS = 2% × value of supply (excluding GST)

Net payment to supplier = invoice value including GST − TDS.

No TDS where location mismatch (proviso to section 51(1))

No TDS if the location of the supplier and the place of supply are both in a State/UT different from the State/UT of registration of the recipient

Both conditions must hold together. For example, the recipient is registered in State X, but the supplier is located in State Y and the place of supply is also in State Y. Then no TDS applies. If only one of them differs from the recipient's State/UT of registration, this exclusion does not apply.

TCS rate (section 52)

0.5% = 0.25% CGST + 0.25% SGST (intra-State) or 0.5% IGST (inter-State)

This is the rate in force from 1 July 2024. It was 1% earlier.

Net value for TCS

Net value = taxable supplies through the ECO in the month (excluding section 9(5) supplies) − taxable supplies returned in the month

TCS = 0.5% × net value. Work out supplier-wise.

Due dates and late fees

Payment to government: by 10th of next month. GSTR-7 (TDS) and GSTR-8 (TCS): by 10th of next month

The TDS certificate (GSTR-7A) is due within 5 days of crediting the amount to the government. Late fee for failing to furnish the certificate is ₹100 per day, maximum ₹5,000. Late fee for GSTR-7 or GSTR-8 under section 47(1) is ₹50 per day (₹25 CGST + ₹25 SGST), maximum ₹5,000 (₹2,500 CGST + ₹2,500 SGST). Nil returns have a lower fee. Check the figures against the latest notification.

How to solve TDS and TCS under GST questions

1. 1Identify who is paying or running the platform. Is the payer a specified deductor (Government department, local authority, governmental agency or notified person) or an e-commerce operator?
2. 2For TDS, check the contract value excluding GST against ₹2,50,000. Use the full contract value, even if payments are made in parts.
3. 3Check the exclusions: reverse charge supplies, exempt or non-taxable supplies, and the case where both the location of the supplier and the place of supply are in a State/UT different from the State/UT of registration of the recipient (proviso to section 51(1)).
4. 4Fix the value. Take the value excluding GST. For TCS, add up taxable supplies through the ECO and subtract returns, and leave out section 9(5) supplies.
5. 5Apply the rate: 2% for TDS and 0.5% for TCS. Split into CGST and SGST for intra-State, or show IGST for inter-State.
6. 6Show the net payment (TDS) or the amount collected (TCS), and who gets the credit: the supplier's electronic cash ledger.
7. 7State compliance: payment by the 10th of the next month, GSTR-7 or GSTR-8 by the 10th, and the certificate within 5 days for TDS.
8. 8Write a one-line conclusion with the final amounts.

Quickest way: Threshold, rate and date check

Common mistakes in TDS and TCS under GST

• Applying the ₹2,50,000 threshold to each payment or each invoice instead of the contract.

  Students read the threshold as a per-transaction limit, like many other limits.

  Fix: The condition is on the total value of supply under a contract. If the contract exceeds ₹2,50,000, deduct on each payment, even small ones.

• Calculating TDS on the invoice value including GST.

  The payer thinks of the full amount to be paid.

  Fix: Take the value excluding the GST indicated in the invoice. Then deduct from the payment.

• Using 1% for TCS or mixing up the TDS and TCS rates.

  The earlier TCS rate was 1%, and old notes and videos still show it.

  Fix: Use 0.5% for TCS (0.25% CGST + 0.25% SGST, or 0.5% IGST) and 2% for TDS. Write the rate beside the label each time.

• Deducting TDS on supplies where the recipient pays tax under reverse charge.

  Students see a government body as the recipient and deduct automatically.

  Fix: TDS applies to taxable supplies where the supplier is liable to pay tax. Skip supplies under reverse charge.

• Forgetting to subtract sales returns when finding the TCS base.

  Students take only the supplies figure from the question.

  Fix: Net value = taxable supplies minus supplies returned in the month. Also exclude section 9(5) supplies.

• Saying the TDS or TCS amount is the supplier's final tax or income.

  Students confuse it with income-tax TDS.

  Fix: Under GST the amount is credited to the supplier's electronic cash ledger. The supplier uses it to pay output tax or may claim a refund. It is not extra tax.

• Mixing up the late fee for the TDS certificate with the late fee for the returns.

  Both are due around the same dates, so students apply one fee to everything.

  Fix: The ₹100 per day (maximum ₹5,000) fee is for failing to furnish the TDS certificate (GSTR-7A). For GSTR-7 or GSTR-8, the section 47(1) late fee is ₹50 per day (₹25 CGST + ₹25 SGST), maximum ₹5,000 (₹2,500 CGST + ₹2,500 SGST). Check the figures against the latest notification.
