In this blog, we explore every aspect of GST — from what it is, how it is calculated, to the GST filing process, deadlines, charges, status checks, and overall procedure. Whether you’re a startup founder, a small business owner, or an accountant, this guide will simplify the complex world of GST for you.
Mastering GST Filing in 2025
Mastering GST Filing in 2025: GST, or Goods and Services Tax, is an indirect tax levied on the supply of goods and services. It is a comprehensive, multi-stage, destination-based tax that is levied at every stage of value addition. GST aims to eliminate the cascading effect of taxes, thereby making products more affordable and simplifying the taxation process.
Why GST Was Introduced?
Mastering GST Filing in 2025: Before GST, India had multiple indirect taxes like VAT, Service Tax, Excise Duty, etc., which created a tangled web of compliance. GST was introduced to:
- Create a unified tax system.
- Promote ease of doing business.
- Reduce corruption and tax evasion.
- Increase government revenue through better compliance.
Types of GST in India
GST in India is categorized into four major types:
- CGST (Central GST) – Levied by the central government.
- SGST (State GST) – Levied by state governments.
- IGST (Integrated GST) – Levied on inter-state transactions.
- UTGST (Union Territory GST) – Levied in union territories.
How is GST Calculated?
Mastering GST Filing in 2025: GST is calculated based on the transaction value, i.e., the price paid for the supply of goods or services. The formula to calculate GST is:
GST = (Original Cost × GST Rate) ÷ 100
For instance, if a product is priced at ₹1,000 and the applicable GST rate is 18%, then:
GST = (1000 × 18) ÷ 100 = ₹180
Total Cost = ₹1,000 + ₹180 = ₹1,180
GST Rates Slab
GST is applied in different slabs:
- 0% – Essential goods and services (e.g., fruits, vegetables).
- 5% – Basic necessity items.
- 12% – Processed foods, mobile phones.
- 18% – Majority of goods and services.
- 28% – Luxury items, automobiles, tobacco.
