Question 1

Who needs to issue a GST invoice?

Accepted Answer

Any GST-registered business or freelancer supplying taxable goods or services must issue a GST invoice. If your annual turnover exceeds ₹20 lakh (₹10 lakh for special category states), GST registration — and invoicing — is mandatory.

Question 2

What is the difference between CGST, SGST, and IGST?

Accepted Answer

CGST (Central GST) and SGST (State GST) are levied on intra-state transactions — both are charged at half the applicable GST rate each. IGST (Integrated GST) is levied on inter-state transactions at the full GST rate and is collected by the central government.

Question 3

Is a GST invoice mandatory for freelancers?

Accepted Answer

Yes, if you are GST-registered. Freelancers providing services like design, software, consulting, or content creation must issue a GST invoice for each transaction. If your income is below the threshold, you can issue a regular invoice without GST.

What details must a GST invoice contain?

A valid GST invoice must include: supplier name, address, and GSTIN; recipient details; unique invoice number and date; HSN/SAC codes; description, quantity, and value of goods/services; applicable GST rate and amount (CGST + SGST or IGST); and the total amount payable.
