Exclusive GST, not a price that already includes tax
Type the amount before GST. The page will not remove tax from an MRP. An inclusive price uses tax = price × rate ÷ (100 + rate), which is a different sum.
The page does not split CGST, SGST, and IGST, and it does not choose 5%, 12%, 18%, or 28% for you. Type the rate that applies.
A salary sketch is one flat percent
On ₹50,000 gross, a 10% tax rate is ₹5,000 of tax. A further ₹1,000 typed as other deductions leaves ₹44,000. The deductions field is rupees, not a second percent.
Regimes, slabs, cess, and provident fund are outside the form. Do not file, and do not argue with a payslip, from this number.
Discount, then GST, is two steps
If a price is discounted and then taxed, run the discount calculator and use the final price as the GST base. This salary and GST article does not do that chain inside one box.
Say the order you used if you quote both figures. “15% off, then 18% GST on the reduced price” is a different total from “18% GST, then 15% off the taxed price.”
