Frequently Asked Questions
Both GST (Goods and Services Tax) and VAT (Value Added Tax) are consumption taxes collected at each stage of the supply chain. The key difference is terminology and implementation: India, Australia, New Zealand, Canada, and Singapore use "GST", while the UK, EU, and many other countries use "VAT". Functionally, both add a percentage tax to the price of goods and services. In India, GST replaced the old VAT system and unified it into one national tax.
Tax Amount = Base Price × (Tax Rate / 100)
Total Price = Base Price + Tax Amount
Example: Base price £500, VAT 20% → Tax = £100 → Total = £600.
Total Price = Base Price + Tax Amount
Example: Base price £500, VAT 20% → Tax = £100 → Total = £600.
Base Price = Inclusive Price / (1 + Rate / 100)
Tax Amount = Inclusive Price − Base Price
Example: VAT-inclusive price £600 at 20% → Base = £600 / 1.20 = £500 → VAT = £100.
Tax Amount = Inclusive Price − Base Price
Example: VAT-inclusive price £600 at 20% → Base = £600 / 1.20 = £500 → VAT = £100.
Standard VAT rates vary by country: UK 20%, France 20%, Germany 19%, Italy 22%, Spain 21%, Netherlands 21%, Sweden 25%, Denmark 25%, Norway 25%, Ireland 23%, Poland 23%, Portugal 23%, Belgium 21%, Austria 20%, Switzerland 7.7%. Most EU countries also have reduced rates for food, medicine, and essential goods.
India has four main GST slabs: 5% (essential goods: tea, sugar, medicines), 12% (processed food, computers, mobile phones), 18% (most services, electronics, restaurants), 28% (luxury items, automobiles, tobacco). Some items like fresh vegetables, milk, and books are at 0% (exempt). For intra-state transactions, GST is split equally into CGST + SGST.
