/ Sector-specific issues for Deep Tech + R&D Startups

Where general-purpose CA misses depth.

Deep Tech + R&D Startups face specific tax + regulatory issues that general-purpose CA often doesn't address well. Our specialist practice covers:

Section 35(2AB) in-house R&D expenditure: Weighted deduction 100% (post 2020; previously 150%) for approved in-house R&D expenses.
Section 35(1)(ii) donation for scientific research: 100% deduction + weighted for approved research institute donations.
Patent box regime (Section 115BBF): 10% concessional tax on royalty from patent (minimum development obligations).
Section 115BAA opt-in vs Section 35 forfeiture: 115BAA forfeits Section 35 benefits; must model which is better.
DST + DBT + MeitY R&D grants: Government research grants - tax treatment + compliance.
IP ownership + inventor assignment: Specific contractual + regulatory requirements.
Deep tech + hardware startup customs on R&D equipment: Research equipment import duty + Section 35 interaction.
Collaboration with IIT / IISc / IIIT: Research + IP commercialisation framework.
