(1) If a bonus in addition to royalties is received upon the grant of an economic interest in a mineral deposit, or standing timber, there shall be allowed to the payee as a cost depletion deduction in respect of the bonus an amount equal to that proportion of his basis for depletion as provided in section 612 and § 1.612-1 which the amount of the bonus bears to the sum of the bonus and the royalties expected to be received. Such allowance shall be deducted from the payee's basis for depletion and the remainder of the basis is recoverable through depletion deductions as the royalties are thereafter received. (But see paragraph (e) of this section.) For example, a taxpayer leases mineral property to another reserving a one-eighth royalty and in addition receives a bonus of $10,000. Assuming that the taxpayer's basis with respect to the mineral property is $21,000 and that the royalties expected to be received are estimated to total $20,000, the depletion on the bonus would be $7,000: [$21,000 (basis) * $10,000 (bonus)] ÷ $30,000 (bonus plus estimated royalties).
The remaining $14,000 of basis will be recovered through depletion as the royalties are received.
