The Goods and Services Tax (GST) rates vary depending on the country and the type of goods or services. Here are some examples from leading countries:
- In India, GST rates were recently rationalized into three main slabs effective September 22, 2025: 5% (for essential items and priority sectors), 18% (standard rate for most goods and services), and 40% (for sin goods and luxury items). There are also rates of 0%, 3%, and 0.25% for certain items, with GST being split into CGST and SGST for intrastate transactions or IGST for interstate transactions.
- In New Zealand, GST is a flat rate of 15% added to most goods and services by registered businesses. GST can be included in the price or added on top separately.
- In Australia, GST is a broad-based tax of 10% on most goods, services, and other items sold or consumed. The GST amount is calculated as 10% of the taxable price.
For an exact calculation, the GST amount is generally calculated as:
GST amount=Price×GST %100\text{GST amount}=\text{Price}\times \frac{\text{GST %}}{100}GST amount=Price×100GST %
and the final price including GST is:
Net price=Cost of product+GST amount\text{Net price}=\text{Cost of product}+\text{GST amount}Net price=Cost of product+GST amount
