GST Invoice Format — What You Must Include

GST Invoice Mein Kya Hona Chahiye?

GST law ke under ek valid tax invoice mein kuch mandatory fields hone chahiye. Agar koi field missing ho toh invoice technically invalid ho sakta hai — aur buyer ko ITC claim mein problem aa sakti hai. Niche saare required fields diye gaye hain:

1. Supplier ka Naam, Address aur GSTIN: Bilkul sahi hona chahiye — GST certificate ke exactly same spelling mein.
2. Invoice Number: Unique consecutive number, financial year mein ek hi baar use hona chahiye.
3. Invoice Date: Jis din supply hui ya invoice generate hua.
4. Buyer ka Naam, Address aur GSTIN (B2B ke liye): Registered dealers ke liye buyer ki details mandatory hain.
5. Place of Supply: State ka naam ya code. Inter-state supply mein especially important hai kyunki IGST ya CGST+SGST determine karta hai.
6. HSN Code / SAC Code: Goods ke liye HSN, services ke liye SAC. Turnover ke basis pe 4-digit ya 6-digit required hota hai.
7. Description of Goods/Services: Clear product ya service description.
8. Quantity aur Unit: Units mein (kg, piece, litre, etc.) clearly mention karo.
9. Unit Price (Rate): Per unit ka price GST ke bina.
10. GST Rate: Applicable GST rate clearly mention karo — 5%, 12%, 18%, ya 28%.
11. GST Amount (CGST/SGST ya IGST): Intra-state supply mein CGST + SGST alag-alag, inter-state mein IGST.
12. Total Amount: GST including total value.
13. Reverse Charge Applicability: "Whether tax is payable on reverse charge basis" — Yes ya No clearly mention karo.
14. Signature ya Digital Signature: Authorized person ka signature ya DSC.

Invoice Numbering Rules

GST law mein invoice numbering ke liye specific rules hain jo follow karne mandatory hain:

• Maximum 16 characters allowed hain invoice number mein.
• Allowed characters: A–Z (capital letters), 0–9 (numbers), hyphen (-), aur forward slash (/).
• Spaces allowed nahi hain invoice number mein.
• Numbers consecutive hone chahiye financial year ke andar.
• Har financial year mein nayi series start kar sakte ho — jaise 2025-26 ke liye "INV-2526-0001" se shuru kar sakte ho.
• Ek baar use kiya gaya invoice number wahi financial year mein dobara use nahi kar sakte.

Common Errors Jo Avoid Karein

• Invoice pe GSTIN nahi: Supplier ka GSTIN missing hona sabse common aur serious error hai. Bina GSTIN ke invoice valid nahi hoti GST purposes ke liye.
• Wrong HSN Code: Product ke liye galat HSN daalte hain — iski wajah se wrong GST rate apply hota hai aur classification disputes ho sakte hain.
• Place of Supply Missing: Inter-state transactions mein place of supply nahi hota toh IGST vs CGST+SGST ka confusion hota hai — jo ITC claim mein reject hota hai.
• Incomplete Buyer Details for B2B: Registered buyer ke liye GSTIN mandatory hai. Sirf naam likhne se unhe ITC nahi milegi — woh dobara invoice maangenge jo extra work hai.
