How Singapore GST works
Singapore charges 9.00% GST on most goods and services. 9% GST on goods and services.
GST is added to the net price to give the gross price the customer pays. To work backwards from a gross price, you divide by 1.09 to find the net amount.
Businesses generally collect GST on sales and reclaim it on purchases, so it is ultimately borne by the end consumer.
Adding vs removing GST
Use "add" when you have a net (tax-exclusive) price and want the final price. Use "remove" when you have a gross (tax-inclusive) price and need the net amount — useful for invoices and expense claims.
This calculator does both and shows the GST amount separately so you can record it correctly.
