Enter an amount and GST rate to add GST on top, or work out the GST already included in a total.
If your price does not yet include GST, choose "Add GST" to see the final price a customer pays. If you have a total that already includes GST and want to know the base price and tax portion, choose "Remove GST."
Which GST rate should I use? Rates vary by product or service category — check current government GST slabs for your specific item.
