Approval under section 10(23G) infrastructure facility status enables tax benefit subject to accounting and audit compliance. Approval under the Income-tax Act was granted to a diesel-engine power generation project as an infrastructure facility for specified assessment years, subject to statutory compliance. The approval is conditional on conformity with the Act and relevant Rules, maintenance of books of account, audit by a qualified accountant, and furnishing the required audit report, and may be withdrawn if the undertaking ceases to operate as an infrastructure facility or fails to meet the accounting and audit requirements.
