Sub-Leasing Strategies for Indian Corporates Holding Excess Office Space

India's corporate office market is sitting on a significant inventory of excess space. As hybrid working patterns have reduced space utilisation across sectors — with average office utilisation in Indian Grade-A buildings estimated at 65–75% of pre-pandemic levels — many large occupiers are managing portfolios that are materially larger than their current needs. Sub-leasing has emerged as the primary tool for monetising this surplus, but it requires careful strategy and execution to succeed.

The mechanics of sub-leasing in India are governed by the head lease between the occupier and the landlord. Most Grade-A commercial leases in India permit sub-leasing to third parties with landlord consent, which cannot be unreasonably withheld. The sub-lessee pays rent to the head tenant, who remains fully liable to the landlord under the head lease — creating a credit risk that must be carefully managed. Sub-rents are typically set below the head lease rent to attract sub-tenants, meaning the head tenant continues to bear a net occupancy cost even after sub-leasing.

The most effective sub-leasing strategy for surplus office space involves three elements. First, packaging — presenting the surplus space in market-ready condition, with fit-out either left in place or upgraded to increase sub-letting appeal. Bare shell space is extremely difficult to sub-let in the Indian market; furnished or Cat B fitted space commands premium sub-rents and leases significantly faster. Second, targeted marketing — identifying the specific occupier types most likely to want the space at the size, floor plate configuration, and location available. A 30,000 sq ft floor in an MNC's Bengaluru tech park will attract different sub-tenants than a 5,000 sq ft suite in a Mumbai CBD building. Third, flexible sub-lease terms — offering shorter initial terms (1–2 years) with renewal options, recognising that potential sub-tenants may be hesitant to commit to long-term obligations on space that is inherently secondary to prime direct leases.

The tax treatment of sub-lease income in India requires careful attention. Sub-lease rental income is taxable as business income, and GST implications — particularly for partial space sub-letting — must be structured correctly to avoid compliance issues.
