Coca-Cola faces $20 billion tax bill in IRS lawsuit
Coca-Cola is a dividend king with 64 straight years of payout increases, a presence in more than 200 countries, and a place in the Dow.
The Internal Revenue Service believes the beverage giant owes up to $20 billion in additional taxes and interest tied to its overseas profit allocations.
A federal appeals court will hear oral arguments on June 25 in Miami to help determine whether that massive claim holds up.
That makes this one of the largest corporate tax fights in American history, and Coca-Cola (KO) shareholders have billions riding on the outcome.
The IRS reallocated $9 billion of Coca-Cola's overseas income
The dispute traces back to an IRS audit of Coca-Cola's federal returns for the 2007 through 2009 tax years, according to the company's press release.
The agency determined that Coca-Cola's foreign manufacturing affiliates were not paying enough for the right to use its trademarks, brand names, and proprietary formulas.
The IRS shifted more than $9 billion of income back to the parent company, rejecting a profit-splitting method Coca-Cola says was previously agreed upon.
Ireland and Brazil together accounted for roughly 85% of that adjustment, a Kluwer International Tax Blog analysis of the case found.

The United States Tax Court sided with the IRS in November 2020 and again in November 2023 on a remaining issue involving a Brazilian affiliate.
A final August 2024 decision held Coca-Cola liable for $2.7 billion in additional federal income tax for those years, according to the company's quarterly SEC filing.
With applicable interest, the total reached about $6 billion, and the company paid that amount in late 2024 to stop interest from growing. A loss on appeal could push the full liability past $20 billion once taxes and interest for subsequent years through 2025 are factored in.
Coca-Cola accuses IRS of transfer pricing bait-and-switch
Coca-Cola argues it relied on a pricing formula from a prior settlement covering the 1987 through 1995 tax years, and the IRS changed course retroactively.
"The biggest focus of the oral argument's going to be this reliance that, 'Hey, you said so, right?'" Chad Martin, a principal at accounting firm Eide Bailly, told Bloomberg Tax.
Martin went further, describing the entire proceeding as "the Super Bowl of transfer pricing controversy," given the unprecedented sums involved.
The IRS counters that Coca-Cola had no grounds to assume the pricing method would persist, and the agency holds broad authority to reallocate income.
Blocked income regulations face new scrutiny after Loper Bright
A separate legal issue concerns the IRS's blocked income regulations, which allow the agency to tax royalties that foreign law prevents a subsidiary from remitting to its home country.
Brazil caps royalty payments from local affiliates to foreign parents, but IRS rules allow the agency to tax the full, uncapped amount, regardless of those restrictions.
The Tax Court upheld that approach using Chevron deference, the doctrine that once required courts to accept reasonable agency interpretations of ambiguous federal statutes.
The Supreme Court struck down Chevron in its June 2024 Loper Bright decision, and Coca-Cola now argues the lower court would have ruled differently.
The IRS maintains Congress explicitly gave the agency authority to write transfer pricing rules, meaning courts should still defer even in the post-Chevron legal landscape.
The ruling will reshape IRS transfer pricing enforcement either way
An IRS victory "will allow them to be more aggressive going forward" in transfer pricing cases, Anne Gordon, vice president for international tax policy at the National Foreign Trade Council, told Bloomberg Tax.
The council filed a brief supporting Coca-Cola, alongside three of the Big Four accounting firms and the United States Chamber of Commerce.
Martin told Bloomberg Tax the case represents an unprecedented transfer pricing dispute.
We're talking about truly massive dollars, almost unprecedented in the transfer pricing context.
An IRS loss in Coca-Cola would make the "whole renewed emphasis on transfer pricing enforcement litigation… problematic" for the agency, University of Michigan law professor Reuven Avi-Yonah told Bloomberg Tax.
The IRS has pursued similar transfer pricing cases against Medtronic and other multinationals in recent years, but last October the Eighth Circuit ruled for 3M in a blocked-income dispute, handing Coca-Cola a helpful precedent for its own appeal.
A conflicting decision from the Eleventh Circuit would create a circuit split, significantly increasing the likelihood of Supreme Court review of the issue.
Coca-Cola's $20 billion case tests the outer limits of IRS transfer pricing power
For investors who hold KO for its reliable dividend and blue-chip stability, the $493 million reserve Coca-Cola disclosed in its June 2025 quarterly filing represents less than 3% of the $20 billion maximum potential exposure.
The company raised its full-year earnings growth outlook after a strong first quarter, with comparable earnings-per-share growth now forecast at 8% to 9%.
An adverse ruling of that magnitude would wipe out the equivalent of multiple years of profit growth in a single court decision.
The ruling will set a precedent that corporate treasurers across the S&P 500 will study closely, particularly at companies routing profits through low-tax foreign affiliates.
For Coca-Cola shareholders and the broader corporate sector alike, the answer depends on where the court draws the line regarding the IRS's enforcement authority.
