Same state: CGST + SGST · other state: IGST. TDS is worked out on the fee before GST and rounded to the rupee. A quick estimate, not tax advice.

How GST is worked out on an invoice

GST is charged on the taxable value: your fee after any discount. At 18%, a fee of ₹50,000 carries ₹9,000 of GST, for an invoice total of ₹59,000.

Client in your state: the GST is split equally into CGST and SGST, so 9% + 9% at the 18% rate.
Client in another state: the whole amount is IGST, 18%.
Client outside India: an export of services, invoiced under a Letter of Undertaking without IGST, or with IGST.

Most professional and consulting services are taxed at 18%. Check the rate for your service's SAC code with your CA if you are unsure.

How TDS affects what you receive

Many business clients deduct TDS (tax deducted at source) before paying you, and deposit it with the government in your name. Where GST is shown separately on the invoice, TDS is worked out on the fee before GST, not on the total.

Example: a ₹50,000 fee at 18% GST for a client in your state, with 10% TDS for professional fees.

Taxable value (your fee)	₹50,000.00
CGST 9%	₹4,500.00
SGST 9%	₹4,500.00
Invoice total	₹59,000.00
TDS deducted by client (10% of ₹50,000)	− ₹5,000.00
Reaches your bank	₹54,000.00

The ₹5,000 is not lost: it is credited against your income tax, and shows in your tax credit statement once the client files their TDS return.

Three ways to calculate

My fee: start from the fee you charge and see the GST, the total and what you receive.
What I receive: enter the amount you want in your bank after TDS, and the calculator finds the fee to quote.
Client's budget: enter the most your client can pay including GST, and it finds the fee that fits.

TDS sections and their new codes

Under the Income-tax Act, 2025, TDS payments are identified by new codes. The common ones for people who invoice for their work:

Payment	Code	Usual rate
Professional fees: architects, interior designers, CAs, lawyers, doctors, engineers	1027	10%
Technical or consultancy services	1026	2%
Director's fees or commission (not salary)	1028	10%
Contract work, paid to an individual or HUF	1023	1%
Contract work, paid to a firm or company	1024	2%
Commission or brokerage	1006	2%
Rent of land, building or furniture	1009	10%
Hire of plant, machinery or equipment	1008	2%
Paid by an individual or HUF above ₹50 lakh a year (Form 141)	—	2%

Thresholds, lower-deduction certificates and other conditions apply. This is a general guide, not tax advice: confirm the section and rate with your client or your CA.

FAQ

Questions, answered

No, where GST is shown separately on the invoice: TDS is worked out on the fee before GST. On a ₹50,000 fee with ₹9,000 GST, 10% TDS is ₹5,000, not ₹5,900.

CGST and SGST, half each, when your client is in the same state as your business; IGST when the client is in another state. For clients outside India, an export of services is invoiced under a Letter of Undertaking without IGST, or with IGST.
