Demystifying International Tax: The Global Transfer Pricing Architecture (Tax Accounting Stacks)

Transfer pricing tells you what to charge. It does not tell you what the charge will cost.

A royalty rate is not just a comparable. It is a net CFC tested income item, a base erosion payment, a foreign tax credit basket entry, a withholding tax event, a customs value, and a GloBE covered tax input. Get the arm's length price exactly right and you can still be wrong about the number that lands on the group's tax line.

This book is about the architecture those prices operate inside. It is written for the person who has to answer the question a CFO actually asks: what is the total tax cost of this structure, and how does it change if we move this function, this asset, or this risk somewhere else.

Forty chapters across eight parts. Seven appendices of working instruments.

Current as of 2026. The United States rewrote its outbound regime in July 2025. GILTI became net CFC tested income, the deduction moved to 40 percent and the effective rate to 12.6 percent, the deemed tangible return was repealed outright, and the credit allowance rose to 90 percent. FDII became foreign-derived deduction eligible income at 33.34 percent and 14 percent. BEAT moved to 10.5 percent. This book is written on those rules, not the ones they replaced.

Part I. The constraint system. The jurisdictional stack, the treaty network as infrastructure, permanent establishment against transfer pricing, the anti-avoidance layer, and the total tax cost framework that runs through the rest of the book.

Part II. The US outbound regime. Subpart F, net CFC tested income, foreign-derived deduction eligible income, BEAT, foreign tax credits and basket mechanics, Section 482 and where it diverges from the OECD standard, and the information reporting obligations.

Part III. Pillar Two. The GloBE architecture and its three mechanisms, the effective tax rate calculation, transfer pricing adjustments as GloBE events, the substance-based income exclusion with its full transition schedule, the repricing of the zero-rate jurisdiction, and compliance as a data architecture problem.

Part IV. Anti-avoidance as a system. Controlled foreign company regimes across the United States, the United Kingdom, Germany, and Japan, anti-hybrid rules, interest limitations, the principal purpose test, digital taxes, and the stress test that runs a structure against all of them at once.

Part V. Beyond income tax. Customs valuation against transfer pricing, VAT and intercompany flows, subnational exposure, indirect tax inside the GloBE calculation, and the integrated total tax cost model.

Part VI. Dispute resolution at scale. Mutual agreement procedure in a multilateral world, arbitration as the binding backstop, advance pricing agreements under a minimum tax regime, litigation as strategy, and the controversy reserve.

Part VII and VIII. The policy, entity rationalization, the total tax cost dashboard, the annual review, scenario planning, and a closing analysis of what fragmentation would mean.

Appendices. A glossary. The Total Tax Cost Model worksheet. The Anti-Avoidance Stress Test. A GloBE compliance checklist. Jurisdictional reference tables. A sample international tax policy framework. And a per-chapter source map naming the governing provision behind every chapter, with the seven chapters that are the author's own frameworks marked as such.

Anti-avoidance rules do not ask whether a structure is legal. They ask whether it is real. This book is about building one that is.
