Common questions

FAQs.

What SAC code should a CA firm use?
The 9982 group covers legal and accounting services. Pick the code that fits the service, such as audit or accounting, from the SAC list.
What if the client deducts TDS?
The invoice shows the gross fee. The client deducts tax when it pays you, and you record the deduction and keep the TDS certificate to claim credit.
Does a small firm need to charge GST?
Only if registration is required for the firm. Check the turnover threshold for services and any other rule that applies to you.
