Tax exemption approval for BOT infrastructure projects conditions continued tax recognition on ongoing regulatory and audit compliance. Approval is granted to a private tollway enterprise for two BOT highway widening and rehabilitation projects as eligible for income tax exemption for the concession period specified in the concession agreement, subject to continued conformity with the statutory provision and income tax rules. The Central Government may withdraw approval if the undertaking ceases to meet eligibility criteria, ceases the defined eligible business, fails to maintain and audit books of account as required, or fails to furnish the mandated audit report.
