Add GST (exclusive) is used when your displayed price does not include tax. You enter the base price, choose the rate, and the tool adds GST on top. Most B2B invoices and wholesale shops use this.
Remove GST (inclusive) is used when your displayed price already includes GST. You enter the final amount and the tool calculates how much of it was the base and how much was tax. This is the standard for retail shops, restaurants, and most consumer-facing prices in India.
Yes. The math is straightforward and matches what your CA or billing software would calculate. Always verify with your accountant for final tax filings.
CGST (Central) and SGST (State) apply when buyer and seller are in the same state — each is half of the total GST. IGST applies when they're in different states — single tax equal to the full GST amount.
If your annual turnover crosses ₹40 lakh (₹20 lakh for services), GST registration is mandatory. Below that, it's optional but recommended for B2B businesses claiming input tax credit.
