Frequently asked questions
How do I remove GST from an inclusive amount?
Choose Remove GST, enter the GST-inclusive total and select the applicable rate. The calculator divides the total by one plus the tax rate to recover the taxable value.
Does this calculator show CGST, SGST and IGST?
Yes. Choose intrastate to split the tax equally into CGST and SGST, or interstate to show the full tax as IGST.
Which GST rate should I use?
Use the rate that applies to your goods or services. This calculator performs the arithmetic but does not determine the legally applicable classification or rate.
