Taxes
(L) Taxes. Taxes include those taxes (other than taxes described in paragraph (e)(3)(iii)(F) of this section) that are otherwise allowable as a deduction to the extent such taxes are attributable to labor, materials, supplies, equipment, land, or facilities used in production or resale activities. (M) Insurance. Insurance includes the cost of insurance on plant or facility, machinery, equipment, materials, property produced, or property acquired for resale. (N) Utilities. Utilities include the cost of electricity, gas, and water. (O) Repairs and maintenance. Repairs and maintenance include the cost of repairing and maintaining equipment or facilities. (P) Engineering and design costs. Engineering and design costs include pre-production costs, such as costs attributable to research, experimental, engineering, and design activities (to the extent that such amounts are not research and experimental expenditures as described in section 174 and the regulations thereunder). (Q) Spoilage. Spoilage includes the costs of rework labor, scrap, and spoilage. (R) Tools and equipment. Tools and equipment include the costs of tools and equipment which are not otherwise capitalized. (S) Quality control. Quality control includes the costs of quality control and inspection. (T) Bidding costs. Bidding costs are costs incurred in the solicitation of contracts (including contracts pertaining to property acquired for resale) ultimately awarded to the taxpayer. The taxpayer must defer all bidding costs paid or incurred in the solicitation of a particular contract until the contract is awarded. If the contract is awarded to the taxpayer, the bidding costs become part of the indirect costs allocated to the subject matter of the contract. If the contract is not awarded to the taxpayer, bidding costs are deductible in the taxable year that the contract is awarded to another party, or in the taxable year that the taxpayer is notified in writing that no contract will be awarded and that the contract (or a similar or related contract) will not be rebid, or in the taxable year that the taxpayer abandons its bid or proposal, whichever occurs first. Abandoning a bid does not include modifying, supplementing, or changing the original bid or proposal. If the taxpayer is awarded only part of the bid (for example, the taxpayer submitted one bid to build each of two different types of products, and the taxpayer was awarded a contract to build only one of the two types of products), the taxpayer shall deduct the portion of the bidding costs related to the portion of the bid not awarded to the taxpayer. In the case of a bid or proposal for a multi-unit contract, all bidding costs must be included in the costs allocated to the subject matter of the contract awarded to the taxpayer to produce or acquire for resale any of such units. For example, where the taxpayer submits one bid to produce three similar turbines and the taxpayer is awarded a contract to produce only two of the three turbines, all bidding costs must be included in the cost of the two turbines. For purposes of this paragraph (e)(3)(ii)(T), a contract means
