How it works
Adding tax multiplies the net price by the rate and adds it on. Removing tax works backwards from a tax-inclusive price to find the original net amount.
Gross = Net × (1 + rate); Net = Gross ÷ (1 + rate)Frequently asked questions

How GST works in Singapore
Singapore charges GST at a standard rate of 9% on most goods and services. It is a consumption tax collected in stages: businesses add it to their sales and reclaim the GST they pay on purchases, so the cost ultimately falls on the final consumer.
Adding and removing GST
To add 9% GST, multiply the net price by 1.09 — so $100 becomes $109, of which $9 is tax. To remove it from a tax-inclusive total, divide by 1.09: $109 ÷ 1.09 = $100 before tax.
