Genuineness of finance leases: assessing officers must verify agreements, asset existence and accounting, and investigate potential fraud. Assessing Officers must scrutinise finance lease agreements and supporting documents to establish genuineness of transaction and asset ownership, examine contractual indicia (commencement date, warranties, lessee liabilities, tax and transfer obligations, rent variation, end-of-lease transfer/purchase option), verify physical existence and compliance through field enquiries, check accounting of lease rentals, investigate return of purchase payments to lessor or associates, test sale-and-leaseback prices and refer valuation if needed, and consider Explanation 4A to section 43(1); false documents may lead to disallowance of depreciation and prosecution.
