GST on BOT Annuity: Unresolved Taxability and Entry 23A
The infrastructure sector in India, particularly road construction, has been navigating a complex regulatory landscape regarding the GST on BOT annuity. The Build-Operate-Transfer (BOT) model is a cornerstone of national highway development, yet the tax treatment of the payments received by developers—specifically annuity receipts—remains a point of significant legal friction. A recent judgment by the Meghalaya High Court in the case of M/s Jorabat Shillong Expressway Ltd. v. Union of India has brought this issue back into the spotlight, unfortunately leaving the core question of taxability of annuity under Entry 23A largely unresolved.
The Concept of BOT Annuity and GST Entry 23A
In a BOT (Annuity) model, the private developer builds the road and, instead of collecting tolls directly from users, receives a periodic ‘annuity’ from the government or the National Highways Authority of India (NHAI). This model shifted the risk of traffic volume from the developer to the government. When GST was introduced, the GST Council recognized the need to provide parity between toll-based projects (which are exempt) and annuity-based projects.
To address this, Notification No. 12/2017-Central Tax (Rate) was amended to include Entry 23A. This entry provides an exemption for “Service by way of access to a road or a bridge on payment of annuity.” For a long time, the industry interpreted this as a blanket exemption for all annuity payments received during the operation phase of a road project. However, the Department of Revenue later introduced Circular No. 150/06/2021-GST, which clarified that this exemption does not apply to the construction of roads, particularly under the Hybrid Annuity Model (HAM). This created a massive rift between taxpayers and the department regarding the taxability of annuity.
Insights from the Meghalaya High Court Ruling
The case of M/s Jorabat Shillong Expressway Ltd. v. Union of India was expected to provide much-needed clarity on whether BOT annuity receipts could still claim the benefit of Entry 23A despite the restrictive circulars issued by the government. The petitioner argued that the annuity payments are essentially consideration for providing access to the road, a service specifically exempted under the law.
The Meghalaya High Court examined the history of the exemption and the subsequent clarifications. However, the court’s decision did not provide a definitive ‘yes’ or ‘no’ to the applicability of the exemption. By leaving the key question of whether GST on BOT annuity is exempt under Entry 23A unresolved, the court has effectively extended the period of uncertainty for highway developers. This lack of judicial finality means that developers must continue to balance the risk of non-payment of GST with the potential for massive future demands and litigation costs.
The Impact of Circular 150/06/2021
The 2021 Circular argued that the GST Council’s intention was never to exempt the underlying construction service. It posited that while ‘toll’ is a payment for access to a road, ‘annuity’ in many contracts is a deferred payment for the construction service itself. This distinction has led to a situation where the department views annuity as a taxable supply of construction services, typically at 12% or 18%, while the industry maintains it is an exempt service of providing road access.
The Persistent Dilemma for Road Developers
The unresolved status of GST on BOT annuity creates several practical challenges for the infrastructure sector:
- Input Tax Credit (ITC) Reversals: If the annuity is treated as exempt, developers may need to reverse ITC on construction inputs, increasing project costs.
- Cash Flow Strain: If developers are forced to pay GST but cannot recover it from the government authorities (NHAI/State bodies) due to contract disputes, it severely impacts their working capital.
- Ongoing Litigation: In the absence of a clear Supreme Court precedent or a definitive High Court ruling like the one in Meghalaya, multiple forums will continue to see conflicting arguments, leading to a bottleneck in the judicial system.
For Chartered Accountants and tax consultants, the taxability of annuity remains a high-risk area for audit and compliance. Until the GST Council or the higher judiciary provides a final word, developers are advised to carefully review their concession agreements and maintain robust documentation to defend their tax positions.
