List of Most Important Constitutional Provisions Added/Modified in the GST Constitutional Amendment Bill

There are many provisions in a constitutional Act. The GST Act also has many provisions that help to maintain the proper execution of taxation in India. Here are some of the most important provisions.
- Article 246A- New Power Structure
This Article provides concurrent powers to the Parliament and state legislature to make laws regarding GST. However, the Parliament holds exclusive power over interstate supplies and business. This article also has a separate clause for petroleum products.
- Article 269A- Taxation of Inter-State Supplies
This article helps to govern the taxation system for interstate supplies of taxable goods and services. The central government levies and collects GST from businesspersons with a GST registration on inter-state trades. According to the Parliament Law, the final tax proceeds are divided between the Union and the State.
Not only outward supplies but inward supplies, like imports, are also deemed as inter-state trade. This article makes it even more precise as it provides power to the authorities to formulate principles for the place of supply.
- Article 279A- GST Council
This article represents the overall rights and responsibilities of the authorities present in the GST Council. This council consists of a chairperson, a Vice Chairperson, other members and state representatives. These people have a responsibility to develop the various laws of GST, such as determining taxable goods and services, developing model GST laws, setting the threshold limit, determining GST rate structure and creating personalised provisions for specified spaces.
However, talking about the voting structure, the Central Government holds ⅓ rd weightage, whereas the State Government holds 2/3rd weightage. Decisions in the Parliament always go in favour of the motion with ¾th or more of the majority.
Key Amendments in the GST Constitutional Amendment Bill
Authoritative individuals in the GST council have been through several meetings to date. In these meetings, they executed many significant amendments to improve the Act and make our taxation system even stronger. Here are some important amendments made to the GST Act.
- Restrictions on Input Tax Credits
According to a new amendment, taxpayers can now claim ITC only on invoices uploaded by their suppliers when they made their ITC.
This helps to ensure the legitimacy of invoices that taxpayers present. This protects the Government from fraudulent activities and strengthens our taxation system.
- Enhanced Composition Scheme
There are some changes in the GST rates and threshold in annual turnover for GST registration, that have made things easier for people of India. Some of these updates impact service providers and people owning a manufacturing and trading business.
Service providers can now opt for a composition scheme at a 6% tax rate, provided they have an annual turnover within ₹50 lakh. The Government of India also raised the threshold for manufacturing and reading businesses from ₹1 crore to ₹1.5 crore.
- E-Invoicing Mandate
The e-invoice mandate requires some businesses to electronically generate and report their finances to the Invoice Registration Policy. This helped to develop automatic and standardised reporting of B2B invoices.
Larger taxpayers with a greater number of transactions can make use of it as it will help them report filings easily and reduce the probability of tax evasion and human errors.
- Exporter’s Revision on Zero-Rated Supplies
In this amendment, the GST Council came to an agreement that exporters can not claim a refund for unutilised ITC unless they physically export those goods.
- Late Fees Rationalisation
The members of the GST council initiated a late fee Rationalisation Amendment. In this amendment, people who delay in filing or do not file GSTR-3B have to pay a penalty. However, it is set to a maximum limit based on a taxpayer’s annual turnover.
- Aadhaar Authentification
This amendment came into action to stop fake registrations and any kind of scams or fraudulent activities taking place. This amendment made it mandatory for taxpayers to go through an Aadhaar verification to get a GST registration.
List of Some Other Significant Changes in the GST Constitutional Amendment Bill

GST came into effect in India in 2017. Since then, there have been numerous updates in the GST constitutional amendment bill that have made it a stronger Act with every amendment. Here are some other significant changes that occurred in the GST Act.
- Restrictions on State Taxation: Article 286 prohibits state taxation on interstate supplies. This article restricts taxation on both inward and outward supplies.
- 5 Years Compensation: This amendment in the Parliament offered a 5-year compensation guarantee to the States. Though the Parliament devises their compensations, it depends on recommendations from members of the GST Council.

Special Features and Safeguards in GST Constitution
There are some special features and safeguards in the GST constitution. Here are some of them:

Changes in the GST Council require 50% state ratification in Article 368. Moreover, it also mandates a Dispute Resolution Mechanism in Article 279A. These decisions in the GST Act help to protect the GST constitution with harmonised tax rates, as our National Market Development guides the Council.
