A taxpayer engaged in the business of farming may treat expenditures which are paid or incurred by him during the taxable year for the purpose of soil or water conservation in respect of land used in farming, or for the prevention of erosion of land used in farming, or for endangered species recovery, as expenses which are not chargeable to capital account. The expenditures so treated shall be allowed as a deduction.
The amount deductible under subsection (a) for any taxable year shall not exceed 25 percent of the gross income derived from farming during the taxable year. If for any taxable year the total of the expenditures treated as expenses which are not chargeable to capital account exceeds 25 percent of the gross income derived from farming during the taxable year, such excess shall be deductible for succeeding taxable years in order of time; but the amount deductible under this section for any one such succeeding taxable year (including the expenditures actually paid or incurred during the taxable year) shall not exceed 25 percent of the gross income derived from farming during the taxable year.
A taxpayer may, without the consent of the Secretary, adopt the method provided in this section for the taxpayer’s first taxable year for which expenditures described in subsection (a) are paid or incurred.
The method adopted under this section shall apply to all expenditures described in subsection (a). The method adopted shall be adhered to in computing taxable income for the taxable year and for all subsequent taxable years unless, with the approval of the Secretary, a change to a different method is authorized with respect to part or all of such expenditures.
In the case of an assessment levied to defray expenditures for property described in clause (ii) of the last sentence of subsection (c)(1), if the amount of such assessment paid or incurred by the taxpayer during the taxable year (determined without the application of this paragraph) is in excess of an amount equal to 10 percent of the aggregate amounts which have been and will be assessed as the taxpayer’s share of the expenditures by the district for such property, and if such excess is more than $500, the entire excess shall be treated as paid or incurred ratably over each of the 9 succeeding taxable years.
If paragraph (1) applies to an assessment and the land with respect to which such assessment was made is sold or otherwise disposed of by the taxpayer (other than by the reason of his death) during the 9 succeeding taxable years, any amount of the excess described in paragraph (1) which has not been treated as paid or incurred for a taxable year ending on or before the sale or other disposition shall be added to the adjusted basis of such land immediately prior to its sale or other disposition and shall not thereafter be treated as paid or incurred ratably under paragraph (1).
If paragraph (1) applies to an assessment and the taxpayer dies during the 9 succeeding taxable years, any amount of the excess described in paragraph (1) which has not been treated as paid or incurred for a taxable year ending before his death shall be treated as paid or incurred in the taxable year in which he dies.
