GST details
Choose whether to add GST on top of an amount, or extract GST from an amount that already includes it.
Same state transaction — GST is split equally between Central (CGST) and State (SGST).
Supports all GST tax slabs — 3%, 5%, 12%, 18%, and 28% — covering essential goods, services, standard items, and luxury products as per the Indian GST structure.
Toggle between "Add GST" (calculate tax on a base price) and "Remove GST" (back-calculate the base price from a GST-inclusive total). Both calculations are instant.
Switch between intrastate (CGST + SGST) and interstate (IGST) transactions. The tool automatically calculates the correct tax split for each type.
Select "Add GST" to calculate tax on a base price, or "Remove GST" to find the pre-tax amount from a total inclusive price.
Enter the amount and select the applicable GST rate (3%, 5%, 12%, 18%, or 28%) for your product or service category.
Choose intrastate or interstate, and instantly see the CGST, SGST, or IGST amounts along with the final payable total.
For intrastate (within the same state) transactions, GST is split equally between Central GST (CGST) and State GST (SGST). For interstate (between two states) transactions, the full GST is levied as Integrated GST (IGST), which is collected by the Central Government and later shared with the destination state.
Use the "Remove GST" mode. Enter the total amount (inclusive of GST) and the applicable rate. The tool will back-calculate: Base Amount = Total ÷ (1 + Rate/100). This is useful when you receive a GST-inclusive invoice and need to split the base price from the tax.
Software and IT services in India are taxed at 18% GST. This applies to SaaS products, IT consulting, software development services, and cloud computing services. Exported software services may qualify for zero-rated GST under LUT (Letter of Undertaking).
