๐ธ How to Show Discounts on a GST Invoice Correctly (Pre-Sale vs Post-Sale Discounts)

Discount dena easy haiโฆ But GST ke under discount dikhana tricky hai ๐
One small mistake can lead to: โ Wrong GST calculation โ ITC issues for buyer โ GSTR-1 mismatch
Letโs simplify it step by step ๐
๐ค Why Discounts Are Complicated in GST
In normal business:
๐ Price kam kiya = discount
But in GST:
๐ When you give discount matters more than how much you give
Because it affects:
- Taxable value
- GST amount
- Buyerโs ITC
- Compliance
๐งพ 1. Pre-Sale Discount (Correct & Simple Way)
This is the best and easiest type of discount
๐ Given before or at the time of sale ๐ Mentioned directly in invoice
โ Example:
MRP = โน10,000 Discount = 10% (โน1,000)
๐ Taxable value = โน9,000 ๐ GST (18%) = โน1,620
๐ Rule:
โ GST is calculated on discounted amount โ No credit note required โ Clean ITC for buyer
๐ 2. Post-Sale Discount (Needs Extra Step)
This is given after invoice is created
Examples:
- Year-end rebate
- Performance bonus
- Special offer after billing
โ Problem:
GST already calculated on full amount
โ Solution:
๐ You MUST issue a Credit Note
๐ก Why Credit Note?
Because:
- You reduce taxable value
- You reverse extra GST
- Buyer adjusts ITC

๐ Impact on Buyerโs ITC
๐ข Pre-Sale Discount:
โ Buyer claims ITC normally
๐ด Post-Sale Discount:
โ Buyer must reverse ITC proportionally
๐ If not done โ compliance issue
โ ๏ธ Common Mistakes to Avoid
โ Applying GST on full amount and then showing discount below โ Not issuing credit note for post-sale discounts โ Treating post-sale discount as pre-sale โ Not informing buyer for ITC reversal โ Incorrect invoice format
