GSTIN

Title

Tax invoice (registered suppliers of taxable supplies). Composition taxpayers and suppliers of exempt goods or services issue a 'Bill of supply' instead.

Not registered for tax

A person who is not registered under GST cannot collect GST or issue a tax invoice. Registered composition taxpayers must not charge GST to customers and issue a bill of supply.

Small invoices

Section 31(3)(b) of the CGST Act lets a registered person skip a tax invoice where the supply is below ₹200, subject to conditions, and issue a consolidated tax invoice at the end of the day for unregistered buyers who do not ask for one.

Payment terms

15 days from acceptance or deemed acceptance if no written agreement; agreed terms cannot exceed 45 days (MSE suppliers only).

Late payment

MSMED Act 2006, sections 15 and 16: where the supplier is a micro or small enterprise registered on Udyam (manufacturing or services), the buyer must pay by the agreed date, which cannot exceed 45 days from acceptance, or within 15 days if no date was agreed. If late, the buyer owes compound interest with monthly rests at three times the bank rate notified by the RBI, overriding any contract term. Outside MSMED, interest is contractual.

Keep records

72 months (6 years) from the due date of the annual return for the year, longer if an appeal or investigation is pending.
