Maximizing Seed R&D Tax Deductions under Section 35(2AB)

Published: August 28, 2026 By: R&D Compliance Consultant DSIR & Tax Compliance

For agribusinesses engaged in hybrid breeding, genetic purity testing, and molecular biology, setting up an in-house R&D unit is highly capital-intensive. To support these efforts, the Department of Scientific and Industrial Research (DSIR) offers a formal recognition system that unlocks substantial fiscal incentives for eligible Indian corporations.

1. The 100% Weighted Tax Deduction under Section 35(2AB)

Historically, companies could claim weighted tax write-offs of 150% or 200% on R&D expenditures. Under the current tax regime, these weighted deductions have been phased out. Today, recognized in-house R&D units are eligible for a flat 100% deduction of all R&D-related capital and revenue expenditures (excluding cost of land and buildings).

This 100% deduction represents a significant corporate tax saving when properly filed and matched with separate R&D accounting ledgers.

2. Customs Duty Exemption under Notification No. 51/96

Recognized units are eligible for a concessional Basic Customs Duty (BCD) on the import of research equipment, laboratory consumables, and specialized scientific software under Notification No. 51/96-Customs. This exemption significantly reduces capital import budgets for high-end genomic sequencers and molecular testing instruments.

3. Important Warning: Rescinded GST Concessions

Agribusinesses must note that the concessional GST rate of 5% on scientific research equipment (under Notification No. 45/2017) was fully rescinded by the GST Council effective July 18, 2022. Integrated GST (IGST) exemptions on imports were also withdrawn. R&D centers must ensure their procurement budgets reflect the standard statutory GST rates.

4. Crucial CA Audit & Ledger Segregation

To maintain DSIR compliance and pass annual inspections, companies must segregate their research expenditures. R&D-specific payroll, consumables, and asset depreciation must be maintained in a separate ledger. At the close of each financial year, a certified Chartered Accountant (CA) must audit these ledgers and submit a certified Form 3CLA report.

Conclusion

Securing and maintaining DSIR recognition requires rigorous scientific documentation and audited accounting ledger practices. Contact our DSIR advisory team to review your eligibility, prepare Form 3CK dossiers, and establish compliant bookkeeping standards.
