Formula & How It Works

TDS is deducted from the gross payment before paying the vendor or service provider.

TDS Amount = Payment Amount (excl. GST) × TDS Rate ÷ 100
Net Payment to Payee = Payment Amount − TDS Amount
Amount Deposited to Govt = TDS Amount

Important: TDS is calculated on the base amount excluding GST. The GST component is not subject to TDS under Income Tax.

Surcharge and Health & Education Cess (4%) apply for payments to non-residents and for payments above ₹50L threshold. Consult your CA for applicable surcharge.

Worked Example

Scenario: You hire a contractor company for ₹80,000 of work (excluding GST). Section 194C applies at 2%.

TDS = ₹80,000 × 2% = ₹1,600

Net to Contractor = ₹80,000 − ₹1,600 = ₹78,400

You deposit ₹1,600 to the government by the 7th of the following month.

If GST @18% is charged on the invoice (₹14,400), the contractor receives: ₹78,400 + ₹14,400 = ₹92,800 total.
