For many foreign-owned businesses, entering the U.S. market is both an opportunity and a shock. The opportunity is obvious: scale, credibility, and access to one of the world’s largest consumer economies. The shock usually comes later—when U.S. tax compliance turns out to be far more layered, aggressive, and unforgiving than expected.
Most international business owners don’t make mistakes because they’re careless. They make mistakes because the U.S. tax system behaves differently than what they’re used to. Rules vary by entity type, by state, and even by how income flows across borders. What looks reasonable from a home-country perspective can quietly create exposure in the U.S.
Below are the most common issues we see foreign-owned businesses encounter—and how thoughtful, early planning helps avoid them.
One of the earliest decisions foreign owners make is forming a U.S. entity. Unfortunately, it’s also one of the most misunderstood.
In many countries, forming a business entity is largely a legal exercise with limited tax flexibility. In the U.S., entity structure directly affects how income is taxed, how losses flow, what gets reported to the IRS, and how profits are eventually repatriated.
Foreign owners often form an LLC believing it automatically simplifies taxes. What they don’t realize is that an LLC is not a tax classification—it’s a legal wrapper. For U.S. tax purposes, an LLC can be treated as a disregarded entity, a partnership, or a corporation, each with very different consequences.
Without intentional planning, businesses may end up:
This is why structure decisions should never be made in isolation. ASAM’s article on The Tax Benefits of Structuring Your U.S. Business as an LLC vs. Corporation explores how early structuring choices influence long-term tax efficiency.
Once a U.S. entity is operational, money almost always moves between it and the foreign parent—management fees, cost reimbursements, royalties, or shared services. These transactions feel internal, but to the IRS, they are prime audit territory.
Transfer pricing rules require related-party transactions to reflect arm’s-length pricing, as if the entities were unrelated. Many foreign-owned businesses either delay addressing transfer pricing or assume it only applies to very large corporations.
In reality, the absence of documentation is often more damaging than imperfect pricing. During an audit, the IRS looks for intent, consistency, and evidence—not just numbers.
Businesses that overlook transfer pricing may find themselves defending:
As discussed in Why Partner-Led CPA Firms Deliver Better Value for International Clients, experienced oversight matters most in nuanced, judgment-heavy areas like transfer pricing.
Many foreign owners assume U.S. compliance is primarily federal. In practice, state and local taxes often create more friction than federal income tax.
Hiring even a single employee can trigger payroll tax registrations. Selling into multiple states can create sales tax obligations—even without a physical office. Expanding operations organically often outpaces compliance updates.
What starts as a lean U.S. presence can quickly become multi-state exposure, especially for:
State tax nexus rules evolve constantly, and compliance is rarely retroactive-friendly. By the time an issue is identified, penalties and interest may already be accumulating.
This is one reason businesses expanding into the U.S. benefit from early planning. ASAM’s guide, Expanding Your Business to the U.S.? Key Tax Steps to Take Before You Start, outlines why operational growth and tax compliance must move together.
One of the most frustrating surprises for foreign-owned businesses is learning that penalties can apply even when tax liability is minimal or zero.
The U.S. tax system places heavy emphasis on disclosure. Forms such as ownership reporting, intercompany transaction disclosures, and foreign asset filings exist to inform—not necessarily to collect tax.
Failure to file them on time can result in penalties that far exceed the tax at stake.
Common examples include:
These filings often fall outside what business owners consider “tax returns,” which is why they’re frequently missed.
Perhaps the most costly mistake foreign-owned businesses make is waiting until a trigger event forces action. That trigger may be an IRS notice, a bank request, a planned acquisition, or an ownership change.
At that point, options narrow. Corrective work becomes more expensive, timelines compress, and risk tolerance disappears.
By contrast, businesses that review their structure and compliance periodically are able to:
This proactive mindset becomes even more important as geopolitical and regulatory environments shift. ASAM’s article on How U.S.–China Trade Relations Impact Small Business Taxes highlights how external policy changes can quickly influence compliance expectations for cross-border businesses.
Foreign-owned businesses rarely fit neatly into templates. Their tax challenges span jurisdictions, currencies, ownership structures, and regulatory systems.
In these situations, partner-led CPA firms offer a distinct advantage. Senior professionals bring continuity, judgment, and accountability—qualities that matter when planning decisions ripple across borders.
Rather than reacting to issues after they surface, experienced advisors help businesses:
This approach is particularly valuable for international families and owners balancing both business and personal considerations, as explored in Estate Planning for Chinese Nationals with U.S. Assets: Key Considerations.
U.S. tax compliance doesn’t have to be a constant source of stress. When addressed early and revisited regularly, it becomes part of a stable foundation for growth.
Foreign-owned businesses that succeed in the U.S. don’t just “file returns.” They understand how structure, reporting, and planning work together—and they choose advisors who do the same.
If your business operates in the U.S., or plans to, now is the right time to ask whether your current structure truly supports your goals. Addressing gaps early is almost always simpler—and far less costly—than fixing them later.
