Introduction

The Real Estate sector underwent a massive regulatory transformation on 1 April 2019. To streamline tax collection and ensure transparency in high-value construction projects, the Central Board of Indirect Taxes and Customs (CBIC) introduced a specific Reverse Charge Mechanism (RCM).

Under Notification No. 07/2019 – Central Tax (Rate), the liability to pay GST was shifted from the supplier to the Promoter (Developer) for certain purchases made from unregistered dealers. This move was designed to ensure that even if a builder sources materials from the unorganized sector, the government still receives the appropriate tax revenue.

Understanding the “Promoter” Liability

Before 2019, RCM on purchases from unregistered dealers was largely suspended. However, for the Real Estate sector, it was reintroduced with specific conditions. The notification specifies that a Promoter must pay tax on a reverse charge basis if they receive goods or services from an unregistered person in the following three categories:

1. The 80% Minimum Purchase Rule (Shortfall)

Promoters are required to procure at least 80% of their total value of inputs and input services from registered suppliers.

• The Rule: If the total value of purchases from registered dealers is less than 80%, the promoter must pay 18% GST on the “shortfall” (the difference).

• Exclusions: Certain items like services by way of grant of development rights, long-term lease of land, or FSI are excluded from this 80% calculation.

2. Cement: The Monthly Mandatory RCM

Unlike other goods, Cement does not follow the 80% threshold rule.

• If a promoter purchases even a single bag of cement from an unregistered supplier, they must pay GST at the applicable rate (currently 28%) under RCM.

• This must be paid in the same month of purchase, regardless of whether the 80% procurement target from registered dealers is met.

3. Capital Goods

Any capital goods (like machinery or cranes) purchased from an unregistered supplier by a promoter for a project attract RCM.

• The promoter must pay GST at the applicable rate for those specific capital goods under reverse charge.

Key Definitions

To ensure error-free compliance, it is vital to understand the terms used in this notification:

• Promoter: Defined as per RERA (2016), it includes any person who constructs or causes to be constructed an independent building or a building consisting of apartments for the purpose of selling.

• Residential Real Estate Project (RREP): A project where the carpet area of the commercial apartments is not more than 15% of the total carpet area of all the apartments in the project.

• FSI (Floor Space Index): The ratio of a building’s total floor area to the size of the land upon which it is built.

Compliance Requirements for Developers

Handling RCM under Section 9(4) requires strict accounting discipline:

• Project-wise Accounts: Promoters must maintain separate accounts for each project to track purchases from registered vs. unregistered suppliers.

• Payment in Cash: Tax under RCM must be paid in cash by debiting the Electronic Cash Ledger. You cannot use Input Tax Credit (ITC) to pay RCM liabilities.

• Self-Invoicing: Since the supplier is unregistered, the promoter is responsible for issuing a Self-Invoice and a Payment Voucher at the time of making payment.

• Reporting: Shortfall tax (the 18% on the 80% gap) should be calculated at the end of the financial year and reported by June 30th of the following year.

Conclusion

The introduction of RCM for promoters on 1 April 2019 was a strategic step to formalize the construction supply chain. By mandating the 80% purchase rule and imposing strict RCM on cement and capital goods, the CBIC has pushed the real estate industry toward more transparent procurement. For developers, “error-free compliance” is no longer just about filing returns; it is about strategic sourcing and meticulous project-wise accounting to avoid the heavy burden of shortfall taxes and penalties.
