IRS Tightens Foreign Business Activity Tax Reviews

August 21, 2026

IRS Tightens Reviews of Foreign Business Activity

Businesses with foreign subsidiaries, branches, related-party transactions, or overseas tax credits are facing more structured IRS review. The increased scrutiny is not based on one new law. Instead, it comes from changes in how the IRS selects, develops, and examines international tax issues.

Large Business and International examination teams now use more detailed risk analysis, broader international reporting data, and stronger documentation procedures when reviewing cross-border business activity.

 

More Data-Driven International Audits

The IRS uses international tax forms and other reporting data to identify returns with a higher risk of noncompliance.

Examiners may review information reported on:

  • Form 5471 for foreign corporations
  • Form 5472 for certain foreign-owned U.S. corporations
  • Form 8858 for foreign disregarded entities and branches
  • Form 8865 for foreign partnerships
  • Form 8833 for treaty-based return positions
  • Schedule UTP for uncertain tax positions
  • Country-by-country reports

Incomplete or inconsistent reporting can increase the risk of additional questions, penalties, or a broader examination.

 

Transfer Pricing Receives Greater Scrutiny

Transfer pricing remains one of the IRS’s main areas of focus when reviewing foreign business activity.

Examination teams may analyze:

  • Related-party pricing policies
  • Intercompany agreements
  • Functions performed by each company
  • Assets used in the business
  • Risks assigned to related entities
  • Economic studies and transfer pricing reports

Businesses may also receive an early request for transfer pricing documentation and have a limited period to provide it.

 

IRS Reviews Can Expand as New Facts Emerge

International audits are generally issue-focused, but the scope may change during the examination. If the IRS identifies additional risks, examiners may add new issues or request more documents.

This makes consistent recordkeeping especially important for businesses with multiple foreign entities or complex cross-border transactions.

 

Foreign Tax Credits Are Also Under Review

The IRS has formalized its review of foreign tax adjustments that affect previously claimed Foreign Tax Credits.

Businesses may need to provide detailed calculations showing how a foreign tax change affects:

  • Prior-year tax returns
  • Foreign Tax Credit categories
  • Credit carryovers
  • Subpart F income
  • Global Intangible Low-Taxed Income
  • Earnings and profits
  • Other international tax attributes

Foreign tax refunds, audit adjustments, and amended foreign returns should be reviewed promptly for possible U.S. reporting consequences.

 

Penalties Are Considered Throughout the Audit

The IRS increasingly considers penalties while developing international tax issues rather than waiting until the end of the examination.

Potential exposure may include transfer pricing penalties and penalties for failing to file complete and accurate international information returns.

 

Final Thoughts

The IRS has strengthened foreign business activity reviews through risk-based audit selection, expanded use of international reporting data, deeper transfer pricing analysis, and more formal review of foreign tax adjustments. Businesses should maintain complete documentation and regularly review their cross-border tax reporting before receiving an IRS notice.
