Goods and Service Tax Network (GSTN)
The Goods and Services Tax Network (GSTN) is a non-profit organization that provides the IT infrastructure and digital platform for India’s Goods and Services Tax (GST) system. In simple terminology, GSTN acts as the technology backbone of GST in India. It helps businesses, taxpayers, and government departments manage GST-related activities online.
- GSTN is a company registered under Section 8 of the Companies Act, 2013, i.e., it is a not-for-profit company.
- Both the Central Government and State Governments provide funding to GSTN.
- GSTN provides the GST portal for use by the Government as well as taxpayers.
- GSTN offers various facilities such as:
- Registration under GST
- Filing of GST returns
- Payment of GST
- Distribution/settlement of IGST
- GSTN acts as the IT backbone of the GST system in India.
Why GSTN is important:
Before GST, different indirect
taxes had separate systems. GSTN created a single unified online system that
made tax compliance more organized and transparent across India.
Official portal:
Key point:
- GST = Tax system
- GSTN = Technology platform that runs and supports
the GST system digitally.
Concept of GSP/ASP:
In the GST ecosystem, GSP and ASP
are technology service providers that help businesses comply with GST
requirements efficiently.
GSP (GST Suvidha Provider)
The GST Suvidha Provider is an
authorized company approved by the Goods and Services Tax Network (GSTN) to
provide secure access to GST portal services through APIs.
Role of GSP:
- Connects business software with GSTN servers
- Enables online filing of GST returns
- Uploads invoices and tax data
- Provides secure communication with GST portal
Simple idea:
GSP acts like a bridge
between taxpayers/business software and GSTN.
Examples of GSP companies:
ASP (Application Service Provider)
The Application Service Provider
develops user-friendly GST software and applications for businesses.
Role of ASP:
- Maintains accounting and invoice software
- Converts business data into GST-compliant format
- Helps prepare GST returns
- Provides dashboards, analytics, reconciliation,
etc.
Simple idea:
ASP acts like the software/service
layer used by businesses.
Relationship between GSTN,
GSP, and ASP
Flow of work:
Business → ASP Software → GSP
→ GSTN
- ASP prepares and formats data
- GSP securely sends it to GSTN
- GSTN processes GST filings
Easy analogy:
- ASP = Typist/Accounting software
- GSP = Courier/Internet gateway
- GSTN = Government GST system
This structure helps businesses
automate GST filing instead of manually entering data on the GST portal.
- GSP stands for GST Suvidha Provider.
- ASP stands for Application Service Provider.
- These are software service providers that help small taxpayers communicate with the GST portal and comply with various legal requirements such as GST return filing, invoice management, reconciliation, etc.
- The system generally works on a pull and push mechanism:
- Data is first pulled from the taxpayer’s accounting/computer system.
- The data is then organised and processed by the software.
- Finally, the organised data is pushed to the GST Portal for filing and compliance purposes.
- ASPs mainly provide the application and user interface, while GSPs provide secure connectivity with the GSTN system.

Process of Decision-Making under GST
- Proposal/Change
initiation
Any change (rate, law, procedure, etc.) is first proposed by the Centre, State governments, or the industry/department and placed before the GST Council. - Deliberation
in GST Council
The proposal is discussed in the GST Council, which includes the Union Finance Minister and State Finance Ministers. - Voting
in GST Council
Decisions are taken by voting: - Centre
vote weight: 1/3
- States
vote weight: 2/3
- Approval
requires 3/4 (75%) of weighted votes of members present and voting.
- Recommendation
stage
If approved, the GST Council sends its recommendation to the Central and State Governments. - Law/Notification
issuance (not Parliament directly)
- Parliament
or State Legislatures do NOT issue notifications.
- Instead:
- Parliament/state
legislatures amend GST laws (e.g., CGST Act, SGST Acts) when required.
- The
Central Government (or State Governments) issues notifications,
circulars, or rules under delegated powers of the GST Acts.
- Implementation
The recommended change becomes effective only when the relevant notification is issued. - Effective
date rule
- The
change applies from the date mentioned in the notification.
- If
no date is mentioned, it becomes effective from the date of issuance
of the notification.
Calculation of 75% voting (Weighted):
Suppose, on a proposal, Central
Government is agreed and 25 States out of 31 States are also agree then:
Clean interpretation of the
GST Council voting logic
The system is a weighted
fractional vote, not a pure percentage system.
So, the correct structure is:
Step-by-step (clean form)
Centre:
States:
Total:
✔ Final result
- Total weighted support ≈ 87.1%
- Required threshold = 75%
- Proposal PASSES
