(B) is determined by the Secretary of the Treasury or his delegate as not increasing substantially the annual income derived from the property.
(2) Payments not chargeable to capital account. The term "excludable portion" does not include that portion of any payment which is properly associated with an amount which is allowable as a deduction for the taxable year in which such amount is paid or incurred.
(c) Election for section not to apply.
(1) In general. The taxpayer may elect not to have this section (and section 1255) apply to any excludable portion (or portion thereof).
