R&D Apportionment and the IC-DISC – An Overlooked Variable in Export Tax Planning

R&D apportionment can have a real impact on the value of an IC-DISC structure, but it is often overlooked. When an IC-DISC commission is computed under the combined taxable income method, research and development costs may reduce the income base used to determine the commission. For exporters with meaningful product development activity, that can directly reduce the expected IC-DISC benefit [1] [2] [3].

Why this matters

Under IRC section 994, an IC-DISC’s income from related-party export transactions may be determined under one of several pricing methods, including the 50-50 combined taxable income method [1]. The regulations explain that combined taxable income is the DISC’s gross receipts from the sale, less the total costs of the DISC and its related supplier that relate to those receipts [2].

Those costs are not limited to direct production costs. They also include deductions definitely related to the export gross receipts and a ratable share of other deductions apportioned under principles consistent with the section 861 allocation rules [2]. Revenue Ruling 86-144 confirms that R&D expenses are part of that analysis in computing DISC combined taxable income [3].

In practical terms, that means businesses with substantial engineering, software development, testing, or product improvement costs may find that those expenditures reduce combined taxable income and therefore reduce the commission payable to the IC-DISC [3] [4].

The tax rules behind the issue

The IC-DISC pricing statute is IRC section 994. Section 994(a) allows DISC income to be determined under the 4% gross receipts method, the 50% combined taxable income method, or a section 482-based method [1]. Treasury Regulation section 1.994-1 provides the detailed mechanics and defines combined taxable income as DISC gross receipts minus the total costs of the DISC and related supplier that relate to those receipts [2].

For R&D apportionment more generally, the current detailed rules are in Treasury Regulation section 1.861-17. That regulation treats R&E expenditures as definitely related to gross intangible income reasonably connected with the relevant SIC code category and apportions those expenditures under prescribed rules [5]. The regulation defines gross intangible income broadly to include income from sales or services derived directly or indirectly from intangible property, while excluding dividends and inclusions under sections 951, 951A, and 1293 [5].

Even though those rules are often discussed in the foreign tax credit context, the DISC authorities make clear that R&D expense apportionment still matters in the export-benefit context. Revenue Ruling 86-144 concluded that the temporary moratorium on certain section 1.861-8 R&D allocation rules for geographic sourcing did not change the computation of DISC or FSC combined taxable income [3]. The ruling explained that combined taxable income is concerned with export profitability, not geographic sourcing for foreign tax credit limitation purposes [3].

A later IRS technical advice memorandum reached the same conclusion and also confirmed that the DISC examples were not limited to buy-sell DISCs, but could apply in the commission DISC setting as well [4].

Common areas where businesses get caught off guard

Companies often underestimate this issue when they:

• develop products in-house while also generating export sales [3];
• incur substantial engineering or software development costs that are economically tied to export products [5];
• assume R&D only matters for section 174 or the research credit, rather than for IC-DISC commission computations [3];
• calculate IC-DISC commissions without carefully reviewing how indirect costs are allocated to export gross receipts [2].

For businesses with meaningful development activity, these costs can materially affect the economics of the IC-DISC structure [3].

What this means for exporters

If your company claims IC-DISC benefits and also invests in innovation, product improvement, or technical development, R&D apportionment should be part of the annual commission analysis. That is especially true where the IC-DISC commission is determined under the combined taxable income method under section 994(a)(2) [1].

A careful review can help answer questions such as:

• Which research costs relate to export products or export-related gross receipts? [5]
• How should those costs be allocated across product lines or categories? [2] [5]
• Are current commission calculations overstating the available IC-DISC benefit? [3]
• Is the company maintaining support for its methodology if the calculation is reviewed? [2]

Bottom line

The IC-DISC remains a valuable export tax planning tool, but the benefit is not determined by export revenue alone. Under section 994 and the related regulations, R&D expenditures can reduce combined taxable income and therefore reduce the commission available under the IC-DISC pricing rules [1] [2]. The IRS authorities addressing DISC combined taxable income make clear that taxpayers cannot ignore R&D apportionment simply because those rules are also discussed in the foreign tax credit context [3] [4].

For exporters with significant development costs, reviewing R&D apportionment is an important step in making sure the IC-DISC calculation is accurate and the expected tax savings are realistic [3].
