The Indian Defence Ministry’s new interim measure will fully reimburse 18% GST on R&D grants, easing cash flow for defence start-ups and MSMEs and signalling continued government support for innovation in the sector.
The Ministry of Defence has moved to remove a long-running tax wrinkle that had been squeezing defence start-ups and MSMEs working on research and development projects. In an office memorandum issued on 27 July, the ministry said the full 18 per cent goods and services tax on grants for defence innovation will be reimbursed, even where the recipient has claimed input tax credit, bringing clarity to a dispute that had unsettled firms working through iDEX and the Technology Development Fund. According to the Indian government’s iDEX scheme and DRDO’s technology-management arm, both programmes are designed to push industry, start-ups and research institutions into defence innovation with grant support, so the tax treatment matters directly to how these projects are funded and delivered.
The clarification follows earlier controversy over what had been described in parts of the industry as “taxing innovation”. In 2025, defence MSMEs began receiving GST notices on grants from the ministry, while some public research bodies were treated differently, prompting complaints about uneven treatment between private and government players. The Ministry of Defence first said in July 2025 that GST would be reimbursed prospectively on grants under iDEX and TDF, and later sought further clarification this April on whether reimbursement should be reduced by any input tax credit claimed by the recipient.
In its latest memorandum, the ministry said GST is payable on the full value of the grant or consideration, regardless of the amount of input tax credit claimed by the entity providing the R&D service, and said the decision was taken with the Department of Revenue. It also made clear that reimbursement arrangements will depend on the contract between the parties, while any refund of GST already paid remains subject to the relevant provisions of the GST law. That makes the move an interim fix rather than a clean, sector-wide exemption, with wider GST Council deliberations on tax waivers for private recipients still pending.
For the defence start-up ecosystem, the practical effect is easier cash flow and less uncertainty in projects that often run on thin margins and long development cycles. The scale is no longer small: the article notes that the Defence Acquisition Council has already cleared more than 30 iDEX products for procurement, with contracts for mass production and deployment crossing ₹1,000 crore, while TDF has backed more than 79 sanctioned projects worth ₹334.02 crore. For Indian founders, suppliers and investors watching defence technology, the message is that the government still wants private innovation in the sector, but the tax treatment of grants is now being nudged into line with that policy goal.
