If, in the case of a taxpayer owning any non-interest-bearing obligation issued at a discount and redeemable for fixed amounts increasing at stated intervals or owning an obligation described in paragraph (2) of subsection (c), the increase in the redemption price of such obligation occurring in the taxable year does not (under the method of accounting used in computing his taxable income) constitute income to him in such year, such taxpayer may, at his election made in his return for any taxable year, treat such increase as income received in such taxable year. If any such election is made with respect to any such obligation, it shall apply also to all such obligations owned by the taxpayer at the beginning of the first taxable year to which it applies and to all such obligations thereafter acquired by him and shall be binding for all subsequent taxable years, unless on application by the taxpayer the Secretary permits him, subject to such conditions as the Secretary deems necessary, to change to a different method. In the case of any such obligations owned by the taxpayer at the beginning of the first taxable year to which his election applies, the increase in the redemption price of such obligations occurring between the date of acquisition (or, in the case of an obligation described in paragraph (2) of subsection (c), the date of acquisition of the series E bond involved) and the first day of such taxable year shall also be treated as income received in such taxable year.

In the case of a taxpayer who
(1) holds a series E United States savings bond at the date of maturity, and

(A)  retains his investment in such series E bond in an obligation of the United States, other than a current income obligation, or

(A) is in the possession of the taxpayer at the close of the merchandise return period, and
(B) is satisfactory to the Secretary.

A repurchase by the taxpayer shall be treated as an adjustment of the sales price rather than as a resale.
(c) Qualified sales to which section applies 

(1) Election of benefits 
This section shall apply to qualified sales of magazines, paperbacks, or records, as the case may be, if and only if the taxpayer makes an election under this section with respect to the trade or business in connection with which such sales are made. An election under this section may be made without the consent of the Secretary.

(2) Initial opening balance 
The opening balance of the account described in paragraph (1) for the first taxable year to which the election applies shall be the largest dollar amount of returned merchandise which would have been taken into account under this section for any of the 3 immediately preceding taxable years if this section had applied to such preceding 3 taxable years.

(A) reduced the excess (if any) of
(i) the opening balance of the suspense account for the taxable year, over

If the initial opening balance exceeds the dollar amount of returned merchandise which would have been taken into account under subsection (a) for the taxable year preceding the first taxable year for which the election is effective if this section had applied to such preceding taxable year, then an amount equal to the amount of such excess shall be included in gross income for such first taxable year.
(5) Subchapter C transactions 
The application of this subsection with respect to a taxpayer which is a party to any transaction with respect to which there is nonrecognition of gain or loss to any party to the transaction by reason of subchapter C shall be determined under regulations prescribed by the Secretary.

26 USC 460 - Special rules for long-term contracts

(a) Requirement that percentage of completion method be used 
In the case of any long-term contract, the taxable income from such contract shall be determined under the percentage of completion method (as modified by subsection (b)).
(b) Percentage of completion method 

(1) Requirements of percentage of completion method 
Except as provided in paragraph (3), in the case of any long-term contract with respect to which the percentage of completion method is used
(A) the percentage of completion shall be determined by comparing costs allocated to the contract under subsection (c) and incurred before the close of the taxable year with the estimated total contract costs, and
(B) upon completion of the contract (or, with respect to any amount properly taken into account after completion of the contract, when such amount is so properly taken into account), the taxpayer shall pay (or shall be entitled to receive) interest computed under the look-back method of paragraph (2).

In the case of any long-term contract with respect to which the percentage of completion method is used, except for purposes of applying the look-back method of paragraph (2), any income under the contract (to the extent not previously includible in gross income) shall be included in gross income for the taxable year following the taxable year in which the contract was completed. For purposes of subtitle F (other than sections 6654 and 6655), any interest required to be paid by the taxpayer under subparagraph (B) shall be treated as an increase in the tax imposed by this chapter for the taxable year in which the contract is completed (or, in the case of interest payable with respect to any amount properly taken into account after completion of the contract, for the taxable year in which the amount is so properly taken into account).

(2) Look-back method 
The interest computed under the look-back method of this paragraph shall be determined by
(A) first[1] allocating income under the contract among taxable years before the year in which the contract is completed on the basis of the actual contract price and costs instead of the estimated contract price and costs,
(B) second, determining (solely for purposes of computing such interest) the overpayment or underpayment of tax for each taxable year referred to in subparagraph (A) which would result solely from the application of subparagraph (A), and
(C) then using the adjusted overpayment rate (as defined in paragraph (7)), compounded daily, on the overpayment or underpayment determined under subparagraph (B).

For purposes of the preceding sentence, any amount properly taken into account after completion of the contract shall be taken into account by discounting (using the Federal mid-term rate determined under section 1274(d) as of the time such amount was properly taken into account) such amount to its value as of the completion of the contract. The taxpayer may elect with respect to any contract to have the preceding sentence not apply to such contract.

(3) Special rules 

(A) Simplified method of cost allocation 
In the case of any long-term contract, the Secretary may prescribe a simplified procedure for allocation of costs to such contract in lieu of the method of allocation under subsection (c).

(ii) in determining overpayments and underpayments for purposes of applying paragraph (2)(B)
(I) any increase in the income under the contract for any taxable year by reason of the allocation under paragraph (2)(A) shall be treated as giving rise to an underpayment determined by applying the highest rate for such year to such increase, and
(II) any decrease in such income for any taxable year by reason of such allocation shall be treated as giving rise to an overpayment determined by applying the highest rate for such year to such decrease, and
(iii) any interest required to be paid by the taxpayer under paragraph (2) shall be paid by such entity (and any interest entitled to be received by the taxpayer under paragraph (2) shall be paid to such entity).
(B) Exceptions 

(i) Closely held pass-thru entities This paragraph shall not apply to any closely held pass-thru entity.
(ii) Foreign contracts This paragraph shall not apply to any contract unless substantially all of the income from such contract is from sources in the United States.
