Adds GST to a fee or extracts it from an inclusive amount, splits CGST and SGST, then deducts TDS to show what actually reaches your account.
How it is worked out: invoice = fee x (1 + GST), TDS = fee x TDS rate, in hand = invoice minus TDS

Questions people ask
Is TDS deducted on the GST part of the invoice?
No. When GST is shown separately, TDS under section 194J or 194C is deducted on the fee only, per CBDT circular 23/2017.
What TDS rate applies to architect fees?
Professional fees fall under section 194J at 10%. Technical services are 2%, contractors under 194C are 1% for individuals and 2% for companies.
Do I have to charge GST on a small practice?
Registration is required once turnover crosses the services threshold, currently 20 lakh rupees in most states and 10 lakh in special category states. Below it you can stay unregistered and not charge GST. Confirm the current threshold before deciding.
