How do you calculate tax inclusive vs exclusive?

For Tax Exclusive (adding tax): Tax = Net × (Rate / 100), and Gross = Net + Tax. For Tax Inclusive (removing tax): Net = Gross / (1 + Rate / 100), and Tax = Gross - Net.

What is the difference between GST and VAT?

GST (Goods and Services Tax) and VAT (Value Added Tax) are conceptually identical multi-stage consumption taxes levied on the value added at each stage of production and distribution. GST is commonly used in India, Canada, and Australia, while VAT is standard across Europe and the UK.

How does CGST and SGST work in GST?

In intra-state sales in dual GST regimes (such as India), the total GST rate is divided equally between the Central Government (CGST 50%) and the State Government (SGST 50%).
