What New IRS Data Reveals About Cross-Border Income and Withholding

Newly released data from the Internal Revenue Service sheds light on the scale of foreign participation in U.S. partnerships and the significant compliance implications that follow.

Based on IRS Statistics of Income data tied to Form 8805 filings for tax year 2022, foreign recipients reported tens of billions of dollars in U.S.-source partnership income, while billions in federal tax were withheld and remitted at the source.

The dataset offers a concrete view of how international investors interact with U.S. pass-through structures and why partnership withholding remains a central IRS enforcement priority.

The Big Picture: What the Numbers Say

IRS SOI data for foreign recipients of U.S.-source partnership income shows:

• 136,031 Forms 8805 filed on behalf of foreign partners.
• $23.3 billion in net taxable income allocable to foreign recipients (income less losses).
• $24.7 billion in gross income reported before losses.
• $6.25 billion in federal tax withholding remitted to the U.S. government.

These figures confirm two realities: U.S. partnerships remain a major vehicle for foreign investment, and withholding/reporting obligations are operating at very large scale.

Why Form 8805 Matters More Than Most People Realize

Form 8805 is not merely informational. It is one of the principal mechanisms through which the IRS enforces tax collection on foreign partners with effectively connected U.S. partnership income.

When a partnership has foreign partners, it is generally responsible for:

• Withholding U.S. tax on effectively connected income.
• Reporting withheld amounts to each foreign partner on Form 8805.
• Providing data the IRS can reconcile against downstream tax filings.

The volume of Form 8805 filings underscores how central this framework is to U.S. international tax administration.

A Compliance Signal, Not Just a Statistic

From a policy and enforcement standpoint, the message is clear: the IRS expects U.S. partnerships to function as tax collection gatekeepers, not just pass-through entities.

With more than $6 billion collected before foreign partners file their own U.S. returns, IRS reliance on upstream withholding is substantial. That elevates the importance of:

• Accurate partner classification.
• Correct income and loss allocations.
• Reliable withholding calculations and reporting workflows.

When those controls fail, risk may extend beyond the foreign investor to the partnership, managers, and controlling parties.

Why This Matters for International & Marine Structures

In industries such as shipping, marine services, yacht ownership, and international investment structures, U.S. partnerships are frequently used for operations or asset-holding.

This IRS data reinforces that:

• Foreign ownership does not reduce U.S. visibility.
• Partnership income is actively tracked and aggregated.
• Withholding failures are measurable and enforceable.

In short, international does not mean offshore from IRS oversight.

MFS Insight: Partnerships Are a Front-Line Enforcement Tool

The key takeaway is not only the amount of income involved, but the enforcement architecture behind the data. Rather than chasing every individual foreign taxpayer first, the IRS can:

• Leverage partnerships as compliance gatekeepers.
• Use standardized forms to aggregate cross-border reporting data.
• Collect tax at source before ultimate return filing.

For businesses and investors, this makes partnership setup, partner classification, and filing accuracy front-line risk decisions, not backend administrative details.

What This Data Tells Smart Operators

• Withholding is not optional or rare in foreign-owned partnership structures.
• Errors scale quickly when partnership income is significant.
• The IRS has meaningful visibility into foreign recipient reporting.
• Documentation and structure quality matter as much as financial results.

Need confidence that your partnership withholding setup is audit ready?

If your structure includes foreign owners, a focused compliance review can help validate withholding, partner classification, and Form 8805 reporting before issues compound.
