International Business Owner Treaty Planning and GILTI Optimization Strategy

The Problem

This software development company operated in three countries with a US C-Corp headquarters in Delaware, a UK subsidiary generating $1.1 million in annual revenue, and an Indian development center generating $500,000 in service revenue. The foreign entities were classified as Controlled Foreign Corporations (CFCs) under IRC §957, subjecting their income to Global Intangible Low-Taxed Income (GILTI) provisions under IRC §951A. The prior accountant was including the full $1.6 million in CFC income as GILTI without claiming any deductions, credits, or treaty benefits.

The company was also paying $280,000 in combined foreign taxes across the UK (25% corporate rate) and India (effective 22% rate) but was not optimizing the Foreign Tax Credit under IRC §901 or considering the GILTI high-tax exclusion under Treas. Reg. §1.951A-2(c)(7). Transfer pricing between the entities was informal and undocumented, creating exposure to both IRS and foreign tax authority adjustments. The combined US and foreign effective tax rate exceeded 48%.

AE Tax Strategy

1. GILTI High-Tax Exclusion and §250 Deduction Under IRC §951A and §250

We analyzed the effective foreign tax rates on a CFC-by-CFC basis to determine eligibility for the GILTI high-tax exclusion under Treas. Reg. §1.951A-2(c)(7). The UK subsidiary's 25% effective rate exceeded the 18.9% threshold (90% of the US rate of 21%), qualifying its $1.1 million in income for the high-tax exclusion. This removed the UK income from the GILTI computation entirely. For the Indian subsidiary, we elected the IRC §250 deduction, which allows a 50% deduction on GILTI inclusions for C-Corp shareholders, effectively taxing the remaining $500,000 in Indian income at 10.5% rather than 21%. Combined annual savings from GILTI optimization: $68,000.

2. Foreign Tax Credit Optimization Under IRC §901 and §904

We restructured the Foreign Tax Credit computation to maximize credits against US tax liability. By properly categorizing income into the general limitation basket and the GILTI basket under IRC §904(d), and by carrying forward excess credits from prior years, we increased the usable FTC by $42,000 annually. We also identified $18,000 in foreign taxes paid on passive category income (interest and royalties from the UK) that had been incorrectly excluded from the credit computation. Annual FTC optimization savings: $38,000.

3. Transfer Pricing Documentation and Intercompany Structure Under IRC §482

We implemented a compliant transfer pricing policy under IRC §482 and the arm's-length standard. We prepared contemporaneous documentation using the Comparable Profits Method (CPM) for the Indian development center and the Transactional Net Margin Method (TNMM) for the UK subsidiary. The restructured intercompany pricing allocated more income to the lower-tax Indian jurisdiction while maintaining defensible arm's-length margins. We also established an intercompany licensing agreement for the US-developed software IP, creating deductible royalty payments from the CFCs to the US parent. Annual savings from transfer pricing optimization: $30,000.

Before & After Comparison

Key Takeaways

• The GILTI high-tax exclusion under Treas. Reg. §1.951A-2(c)(7) can eliminate GILTI inclusions entirely for CFCs operating in countries with effective tax rates above 18.9%. The UK, Japan, Germany, and France typically qualify.
• C-Corp shareholders of CFCs should always evaluate the IRC §250 deduction, which reduces the effective US tax rate on GILTI inclusions from 21% to 10.5%, before computing Foreign Tax Credits.
• Transfer pricing documentation is not optional for companies with intercompany transactions. The IRS imposes penalties of 20-40% on transfer pricing adjustments when contemporaneous documentation is not maintained.
• Foreign Tax Credits must be properly allocated between the general limitation, passive category, and GILTI baskets under IRC §904(d). Misallocation frequently results in lost credits and overpayment of US tax.
