What does a gst (9%) calculation tell me?
Adds Singapore's 9% Goods and Services Tax to a price.
What is the formula?
GST = price × 9%; price with GST = price × 1.09.
What do I need to enter?
Price before GST (S$).
Is this the same as my IRAS bill?
It is an estimate based on the published rates. Your notice of assessment will reflect all reliefs, rebates and income IRAS holds for you.
Can you show an example?
For example, with these inputs:
- Price before GST (S$): 100
the calculator returns:
- GST at 9%: S$9.00
- Price including GST: S$109.00
Any tips?
- GST-registered businesses must show prices inclusive of GST to consumers, so a listed retail price already includes the 9%.
- Personal income tax relief is capped at S$80,000 a year in total.
- Keep receipts and records for at least five years in case IRAS asks for them.
Background
The Goods and Services Tax rose from 8% to 9% on 1 January 2024. Businesses with taxable turnover above S$1 million must register, and GST-registered retailers must quote prices to consumers inclusive of GST, so most shelf prices already include it.
Reliefs lower chargeable income before rates apply. Common ones include earned income relief, CPF relief for employee contributions, parent and handicapped parent relief, working mother's child relief, NSman relief, course fees relief, and relief for SRS contributions and CPF cash top-ups. Total personal reliefs are capped at S$80,000 a year.
You are generally a tax resident if you are a citizen or PR who normally lives here, or a foreigner who has stayed or worked in Singapore for at least 183 days in the calendar year. Non-residents do not get personal reliefs and are taxed differently, which is why residency status matters so much for expatriates.
