GST Return Filing

GST return filing shows details of income, sales, expenses, and purchases. A GST-registered taxpayer files this document with tax authorities. Moreover, GST applies to most goods and services in India. However, petroleum products, alcohol, and electricity do not fall under GST.
What is GST?
Suppliers collect GST and pay it to the government. India introduced GST in 2017 to simplify the tax system.
Previously, businesses paid multiple indirect taxes. Now, GST combines most of them into one system. Therefore, it simplifies taxation and improves transparency.
GSTIN (GST return Filing)
GSTIN acts as a 15-character identification number for taxpayers.
- The first two characters represent the state code
- The next 10 characters show the PAN number
- The 13th digit represents the entity number
- The 14th digit is “Z” by default
- The 15th digit is a unique code

Key points of GST return filling
1. Interstate Transaction (from one state to another)
When goods move between states, businesses apply IGST. Therefore, invoices include IGST details.
2. Intrastate Transactions (within one state)
When transactions occur within a state, businesses apply CGST and SGST. As a result, they divide the tax equally.
3. Output GST
Businesses collect output GST on sales.
4. Input GST
Businesses pay input GST on purchases.
5. GST Payable
You calculate GST payable as:
👉 Input GST – Output GST
6. Rates of GST
The government applies four GST rates: 5%, 12%, 18%, and 28%.
