Understanding Sales Tax in India
What is Sales Tax?
Sales Tax is a consumption-based indirect tax imposed on the supply of goods. In India, it has been replaced by GST (Goods and Services Tax) from July 1, 2017. However, the term "sales tax" is still commonly used to refer to various taxes on goods. The tax is calculated on the selling price and collected by the seller from the buyer, then remitted to the government.

SGST = Net Value × (Tax Rate / 100) ÷ 2
For Inter-State Transaction (IGST):
IGST = Net Value × (Tax Rate / 100)
Final Price = Net Value + Total Tax

Frequently Asked Questions on Sales Tax & GST
Is sales tax the same as GST?
Not exactly. GST replaced sales tax, VAT, excise, and service tax from July 2017. GST is more comprehensive, covers both goods and services, and has a unified rate structure across states.
What's the difference between CGST, SGST, and IGST?
CGST (Central) and SGST (State) are split 50-50 for intra-state sales. IGST (Integrated) is full tax for inter-state sales, collected and distributed. IGST allows ITC across states.
Can I claim ITC on a motor vehicle purchase?
No. ITC is not available on motor vehicles (except specific business use like transport). Also no ITC on fuel, entertainment, accommodation (unless B2B), and personal consumption items.
Do I need GST registration if my turnover is below ₹40L?
No, not mandatory below ₹40L. But you can voluntarily register to claim ITC and appear more credible to B2B customers. Consider your business model before deciding.
How do I calculate GST on discounted prices?
Tax is calculated on net value after discount. If original price ₹1,000, discount 10% (₹100), tax applies on ₹900. This reduces GST liability for the seller.
What's reverse charge in GST?
Buyer pays GST instead of seller (applicable for unregistered suppliers, inter-state B2B). Buyer gets ITC immediately. Common in construction, services from unregistered vendors.
Can GST rate change for the same product?
No. GST rate is fixed per product category and doesn't change mid-year. However, government can change rates, which applies to future transactions only.
What happens if I don't file GST returns on time?
Penalties apply (₹100-₹500 daily, capped per category), blocked GSTR-1 filing, possible liability to pay GST without ITC, and audit scrutiny. File even if nil GST liability.
