How Does the GST Composition Scheme Differ from the Reverse Charge Mechanism in GST?

Goods and Services Tax (GST) is a comprehensive indirect tax structure introduced in India to bring uniformity across various levels of taxation. GST is applicable to businesses and entities engaged in the supply of goods or services. Two critical components of the GST system are the GST Composition Scheme and the Reverse Charge Mechanism (RCM). While both aim to ensure compliance and broaden the tax base, they differ significantly in terms of applicability, purpose, and operational structure. Let us explore how the GST Composition Scheme differs from the Reverse Charge Mechanism in GST.
Understanding the GST Composition Scheme
The GST Composition Scheme is a simplified tax framework designed for small businesses to reduce their compliance burden and to help them compete in the market. Under this scheme, eligible taxpayers pay tax at a fixed percentage of their turnover rather than the standard GST rates, making it easier for them to comply with tax regulations without hiring experts.
The scheme is optional and primarily caters to small and medium enterprises (SMEs) whose aggregate turnover does not exceed ₹1.5 crore annually (₹75 lakh for businesses in select states). Businesses registered under this scheme cannot collect GST from customers, nor can they claim input tax credit. Instead, they must pay tax out of pocket on their turnover at the prescribed rates:
– 1% for manufacturers and traders,
– 5% for restaurant services,
– 6% for other service providers.
Eligible Businesses for GST Composition Scheme
The GST Composition Scheme is limited to specific types of businesses. Manufacturers, traders, and service providers (with certain restrictions) having a turnover below the prescribed threshold can opt into the scheme. However, businesses involved in inter-state supply of goods, casual taxable persons, non-resident taxable persons, and e-commerce operators are ineligible.
This scheme simplifies taxation for small taxpayers by reducing procedural complexity, such as filing only one quarterly return (Form CMP-08), thus saving time and resources.
Limitations of the GST Composition Scheme
While the composition scheme offers simplicity, it is not devoid of limitations. Since suppliers cannot issue tax invoices, businesses under this scheme cannot provide an input tax credit to their buyers. This makes the scheme less suitable for businesses that have B2B transactions where customers expect to claim input tax credits.
Understanding the Reverse Charge Mechanism in GST
The Reverse Charge Mechanism (RCM) is another component of the GST regime, but it has an entirely different role. Unlike the GST Composition Scheme, which simplifies compliance for small businesses, RCM shifts the responsibility of paying GST from the supplier to the recipient of goods or services.
In the conventional tax system, a supplier collects taxes from the buyer and remits them to the government. However, under RCM, the buyer or recipient is liable to pay GST on the procurement of goods or services.
Applicability of Reverse Charge Mechanism
RCM is explicitly mandated for specific scenarios and not something a business can voluntarily opt into, unlike the GST Composition Scheme. It applies in the following situations:
- Supply by unregistered persons to registered persons: If a registered taxpayer buys goods or services from an unregistered supplier, the registered recipient bears the liability to pay GST under RCM.
- Notified supplies: Certain categories of goods and services (as per GST regulations) are subject to RCM regardless of the supplier’s registration status. Notable examples include legal services provided by an advocate, services by a goods transport agency, and import of services.
Compliance and Reporting under RCM
For taxpayers liable under RCM, compliance requirements differ from those under the GST Composition Scheme. Recipients must issue a self-invoice if the supplier is unregistered, pay the applicable GST on these transactions, and claim the input tax credit (if eligible) when filing a regular GST return. Tax liability under RCM must also be paid in cash, as it cannot be offset using input tax credit.
Additional compliance under RCM involves maintaining proper records, ensuring timely payment of tax, and filing separate details of RCM transactions in the GSTR-3B and GSTR-1 forms.
Key Differences Between GST Composition Scheme and Reverse Charge Mechanism in GST
-
Purpose:
– The GST Composition Scheme is designed to simplify taxation for small taxpayers and reduce compliance costs.
– The Reverse Charge Mechanism is meant to widen the tax net by ensuring tax compliance in cases where the supplier is not liable to pay GST or in cases of imports.
-
Eligibility:
– The composition scheme is optional and targeted specifically at small businesses within prescribed annual turnover limits.
– RCM is mandatory for transactions and circumstances specified by GST law, such as purchases from unregistered suppliers or distinct notified goods and services.
-
Tax Liability:
– Under the GST Composition Scheme, the supplier pays GST at a reduced rate based on their turnover.
– Under RCM, the obligation to pay GST shifts to the recipient of goods or services.
-
Input Tax Credit:
– Businesses under the composition scheme cannot claim input tax credit.
– In RCM, the recipient can claim input tax credit for the GST paid, subject to conditions.
-
Return Filing:
– Taxpayers in the composition scheme file quarterly returns (CMP-08) along with an annual return.
– RCM-related transactions are recorded in the regular GSTR-1 and GSTR-3B filings.
-
Scope of Application:
– The GST Composition Scheme is broader in scope but excludes businesses involved in inter-state and e-commerce-based supplies.
– RCM has targeted applications and is limited to notified services and specific types of suppliers.
Conclusion
Both the GST Composition Scheme and the Reverse Charge Mechanism in GST serve critical but distinct purposes within the broader framework of Goods and Services Tax. While the composition scheme streamlines compliance for small businesses, RCM ensures the government collects taxes from unregistered vendors or specific transactions. For businesses, understanding the intricacies of these mechanisms is crucial to ensuring smooth operations and full compliance with GST laws. Making an informed choice about whether to opt for the composition scheme or comply with RCM provisions will depend on business turnover, the nature of transactions, and operational priorities.
Summary
The GST Composition Scheme and Reverse Charge Mechanism (RCM) are two tools within the GST ecosystem, with distinct goals and applications. The composition scheme simplifies tax compliance for small businesses by allowing them to pay GST at a fixed rate on turnover, making it well-suited for firms with limited resources and simple operational models. This scheme reduces compliance by requiring only quarterly returns and exempting taxpayers from filing monthly submissions. It also excludes businesses with inter-state supplies, e-commerce operators, or turnover beyond the ₹1.5 crore threshold.
On the other hand, the Reverse Charge Mechanism shifts the tax liability from the supplier to the recipient of goods or services. RCM plays a vital role in capturing transactions involving unregistered suppliers or taxable categories like legal services, imported services, and goods transportation. RCM compliance can be challenging as it demands recipients to self-invoice, pay the tax in cash, and maintain proper records in GST filings.
The two mechanisms differ in purpose, applicability, compliance rates, and eligibility criteria. Understanding the differences between the GST Composition Scheme and RCM helps businesses make informed decisions to fulfill their tax obligations effectively and within the framework of GST.
