Common GST Calculation Mistakes
- Confusing Inclusive and Exclusive: Applying the exclusive GST formula to an inclusive price causes tax overcalculation.
- Incorrect State Splits: Forgetting that local sales require CGST/SGST splits rather than flat IGST allocations.
- Using Wrong Rate Slabs: Applying incorrect slabs to mixed items (such as billing services at 12% instead of 18%).
Pro Tips for GST Calculations
- Deduct Taxes First: If setting target product margins, calculate the base rate first using Inclusive mode.
- Leverage ITC: Track all purchase invoice GST returns to offset sales liabilities during GSTR filings.
