I have just published a new article on FinoLib, my free finance education library: BEPS Explained: Base Erosion and Profit Shifting. It is part of Volume III: Finance Encyclopedia. Below is a summary of the topic in plain, expert language, so you can follow the idea even before you open the full article.
The idea in plain words
BEPS stands for base erosion and profit shifting. It means moving profit to low-tax places where there is little real activity. In 2015 the OECD and G20 answered with rules on hybrid arrangements, controlled foreign companies, interest deductions, treaty abuse and transparency. Pillar One’s plan to reallocate profit to market countries has stalled, but its Amount B simplification for routine distributors survives.
Key points
■The OECD estimated in 2015 that profit shifting cost $100 billion to $240 billion a year.
■Three-tier documentation means a master file, a local file and a country-by-country report for groups with revenue of €750 million or more.
■US anti-hybrid rules (§267A) and the 30% interest cap (§163(j)) are the domestic versions of Actions 2 and 4.
■Estimates of shifted profit range from about 36% of multinational profits to far smaller figures, depending on how the data are corrected.
A closer look
Base Erosion and Profit Shifting (BEPS) refers to tax planning that exploits gaps and mismatches between countries’ tax rules to shift profit to low- or no-tax jurisdictions where little real economic activity takes place, eroding the tax base of the countries where the value was created. After the 2008 crisis, public and political concern about large multinationals paying very low effective tax rates led the G20 to ask the OECD for a coordinated BEPS Action Plan (2013), whose 15 actions were delivered as a final package in October 2015. The measures are now carried forward by the OECD/G20 Inclusive Framework on BEPS, which had 148 member jurisdictions as of January 2026. They include country-by-country reporting, limits on interest deductions, rules against hybrid mismatches and treaty abuse, and, the most far-reaching later outcome, the global minimum tax covered next.
When the OECD presented the final BEPS reports to G20 finance ministers in October 2015, it estimated that profit shifting cost governments $100 billion to $240 billion a year, 4% to 10% of global corporate income tax revenue. The package attacked the three levers of Section 4.1: Why Multinational Tax Structuring Exists with matching rules, most of which the US has its own version of:
Decision rule
Read your own country-by-country report the way an auditor will. For each jurisdiction, divide its share of group profit by its share of employees and of tangible assets. Where profit share is several times the people-and-assets share (for example, 30% of profit with 2% of staff is 30% ÷ 2% = 15 times), expect a risk review, and make sure the master file explains which valuable functions or intangibles justify it. Where no such explanation exists, change the pricing or move the functions before the auditor asks.
The costliest mistake
Keeping a pre-2018 hybrid financing in place. A US subsidiary pays $50 million a year of interest to a foreign affiliate on an instrument the affiliate’s country treats as equity, so the receipt is an exempt dividend there. Before §267A, the US deduction saved $50,000,000 × 21% = $10,500,000 a year with no tax anywhere on the other side. Under §267A the deduction is disallowed: the group’s US tax rises by $10,500,000 a year, and if the return was filed claiming the deduction, interest and penalties follow. Inventory every intra-group instrument and entity classification on both sides of the border.
Career Insight
Country-by-country reporting — requiring large multinationals to disclose revenue, profit, and tax paid in every single country they operate in, submitted confidentially to tax authorities — was BEPS’s single most practically significant transparency measure, since it gave tax authorities worldwide, for the first time, a global view of exactly where a multinational’s profit was being reported relative to where its actual employees and operations were located.
Where Experts Disagree: How Much Profit Is Really Shifted?
The large estimate. Tørsløv, Wier and Zucman (The Missing Profits of Nations, Review of Economic Studies, 2022) compare the profitability of foreign-owned and local firms. Affiliates in tax havens are an order of magnitude more profitable relative to their wage bill: for US multinationals in 2015, pre-tax profits were 346% of wages in haven affiliates against 46% in non-haven affiliates.
Recap
BEPS named profit shifting to low-tax places and produced the 2015 countermeasures: anti-hybrid, CFC and interest rules, treaty anti-abuse and three-tier documentation with country-by-country reporting. How much profit is shifted is disputed, Pillar One’s Amount A has stalled, and Amount B survives as an optional simplification for routine distributors.
