Corporate Tax Dollars Flowing Beyond U.S. Borders

Every busy season, someone in the office eventually says, “Show me where the cash actually went.” Thanks to a new Financial Accounting Standards Board disclosure rule, we can now say that about corporate income taxes, too. For the first time, large U.S. public companies must break out cash taxes paid by country in their annual reports. The early results are raising eyebrows. In many cases, major American multinationals are paying more income tax abroad than they are to the U.S. Treasury. That is not a political talking point. It is showing up in the footnotes.

Are U.S. companies paying more tax?

Start with Boeing. According to recent filings analyzed by the Financial Accountability and Corporate Transparency Coalition, Boeing paid more than twice as much tax in Germany as it did in the United States. Tesla paid roughly $28 million to the U.S. government in 2025. In the same period, it paid about $751 million to China. That is a 27-to- 1 ratio. Let that sink in for a minute. PepsiCo generated more than half of its net revenue in the U.S., yet reported less than 10% of its pre-tax income domestically. GE Vernova generated nearly half its revenue in the U.S. but reported pre-tax profits of under 3% here. The rest showed up in places like Ireland, Singapore, Bermuda, and the Netherlands.

These numbers became visible because FASB issued an income tax disclosure standard in late 2023, effective for public companies last year. The rule requires more granular country-by-country disclosures of cash taxes paid and tax rate reconciling items. For years, investors asked for this. Now the curtain is up.

Is Pillar Two quietly shifting revenue overseas?

Layer in global developments. Nearly 60 jurisdictions have adopted the OECD’s 15% global minimum tax under Pillar Two. The U.S. has not conformed its rules to that framework. Instead, Treasury has issued guidance that effectively shields many U.S. companies from parts of Pillar Two after political pressure around so-called retaliatory taxes. Yet companies still report higher tax payments abroad. Why? Because other countries implemented domestic minimum top up taxes. If the effective tax rate in a jurisdiction falls below 15%, local authorities collect the difference. In plain English, if the U.S. does not tax the income, someone else might.

We are already seeing disclosures that reflect those foreign minimum taxes. At the same time, companies are reporting exposure to the U.S. corporate alternative minimum tax, enacted under the Inflation Reduction Act at 15% of adjusted financial statement income. In many cases, the impact shows up as valuation allowances against deferred tax assets rather than immediate cash payments. If you run tax provision calculations for a living, you know this is where things get messy fast. Foreign tax credits, GILTI, Subpart F, CAMT, domestic minimum taxes, safe harbors. The rules are complex enough to make even seasoned tax directors mutter, “This is a lot.”

Is the tax footnote now a risk disclosure?

These new disclosures do not change the tax law. They change transparency. Investors can now see how much a company’s effective rate depends on low tax jurisdictions traditionally associated with profit shifting. If a meaningful slice of the rate benefit comes from Ireland, Bermuda, or Singapore, that creates exposure to future reform. It also raises enforcement risk and reputational risk. Think about it from a controller’s seat. If your company’s consolidated effective tax rate relies on structures that reduce U.S. taxable income while booking profits elsewhere, what happens if Congress tightens GILTI or modifies foreign tax credit rules? What if more countries introduce top-up taxes? What if country-by-country reporting expands under EU and Australian rules later this year?

This is not abstract. Microsoft and Apple, among others, will soon provide more public country-by-country data under EU and Australian transparency laws. Once that information is public, analysts will connect the dots. As Warren Buffett likes to say, “Only when the tide goes out do you discover who’s been swimming naked.” Increased disclosure lowers the waterline.

What should CPA firms and finance teams watch next?

For CPA firms advising multinationals, this is not about grandstanding. It is about risk assessment and planning. Imagine a mid-sized U.S. manufacturing group with IP parked in Ireland and cost-sharing arrangements in Singapore. For years, the structure delivered a tidy effective rate. Now the CFO reads headlines about global minimum taxes and sees competitors disclosing higher foreign cash taxes. The question becomes: do we hold the line, restructure, or prepare for higher global tax friction? Advisors will need to model multiple scenarios. What if the U.S. aligns more closely with Pillar Two? What if CAMT interacts with foreign tax credits in unexpected ways? What if state conformity adds another wrinkle? This is where the rubber meets the road.

On the audit side, tax footnotes just became more sensitive. Auditors will face more scrutiny around uncertain tax positions, valuation allowances, and the sustainability of rate assumptions. Expect more pointed questions from audit committees. Expect more back and forth with tax departments trying to explain why U.S. cash taxes look thin compared to foreign payments. And let’s be honest, optics matter. When a company that markets itself as quintessentially American pays materially more tax to China or Germany than to the U.S., boards will at least ask the question.

Takeaway

The new FASB disclosure rule does not rewrite the Internal Revenue Code. It does something subtler. It gives investors, policymakers, and the public a clearer picture of where corporate tax dollars actually land. For practitioners, the takeaway is straightforward. The era of vague aggregate tax reporting is fading. Country-level transparency is expanding, both in the U.S. and abroad. That will influence tax planning, provision analysis, audit scrutiny, and possibly future legislation. So, keep an eye on the tax footnote this year. Read the country tables. Compare effective rates across jurisdictions. Ask whether current structures still make sense in a world of minimum taxes and growing transparency. Because once the numbers are out there, you cannot put the toothpaste back in the tube.
