Telecommunication licence fee amortisation and transfer rules govern deduction, business income treatment, and depreciation restrictions. Capital expenditure for acquiring a right to operate telecommunication services is deductible in equal instalments over the period for which the licence remains in force, beginning from the later of the year of business commencement or actual payment of the licence fee. On transfer of the licence, the remaining unallowed expenditure may be allowed as a deduction on a loss, the excess may be taxed as business income on a gain, and no further deduction is available where the transfer proceeds equal or exceed the unallowed amount. The material also states that depreciation cannot be claimed where amortisation is allowed, and records the earlier section 35ABB regime and related treatment of telecom licence transfers.
