The GST Framework
Goods and Services Tax (GST) is a multi-stage, destination-based tax that is levied on every value addition. In India, it has replaced almost all indirect taxes like VAT, Service Tax, and Excise Duty to create a "One Nation, One Tax" system.
Note: GST is calculated on the transaction value. Businesses can claim Input Tax Credit (ITC) for GST paid on purchases, effectively taxing only the value added at each stage.

1. What is GST and how is it calculated?
GST (Goods and Services Tax) is an indirect tax used in India. To calculate it manually: GST Amount = (Original Cost × GST %) / 100. Net Price = Original Cost + GST Amount.
2. What is the difference between Inclusive and Exclusive GST?
Inclusive GST means the price already contains the tax amount. Exclusive GST means the tax is added on top of the base price. HQCalc handles both calculations instantly.
3. What are the current GST slabs in India?
The standard GST slabs are 5%, 12%, 18%, and 28%. Some essential goods are at 0%, while luxury items may attract an additional Compensation Cess.
4. When should I use IGST instead of CGST/SGST?
Use IGST (Integrated GST) for interstate transactions (between two different states). Use CGST and SGST for intrastate transactions (within the same state).
5. What is Input Tax Credit (ITC)?
ITC allows businesses to reduce the tax they have already paid on inputs from the tax they collect on outputs. This prevents cascading taxes (tax on tax).
6. Who needs to register for GST in 2026?
Generally, businesses with an annual turnover exceeding ₹40 Lakhs (for goods) or ₹20 Lakhs (for services) must register. Limits vary for North-Eastern states.
7. How to calculate GST Inclusive price manually?
Formula: GST Amount = Value inclusive of GST - [Value inclusive of GST / {1 + (Tax rate / 100)}]. Our tool automates this to avoid rounding errors.
8. Is GST applicable on exports from India?
Exports are considered 'Zero-Rated Supplies.' You don't pay GST on exports and can claim a refund for the tax paid on inputs used to manufacture those exports.
9. What is the GST Composition Scheme?
It is a simple scheme for small taxpayers (turnover < ₹1.5 Cr) to pay GST at a fixed percentage of turnover and file simplified quarterly returns.
10. Is HQCalc GST Calculator updated for 2026?
Yes, our engine is kept in sync with the latest GST Council notifications and departmental circulars to ensure compliance.
