International Tax Services

Cross-Border Tax Planning & Compliance

Cross-border activity creates tax and reporting obligations in multiple jurisdictions. Whether you are an individual with income, assets, or family ties abroad, or an organization expanding into new markets, EisnerAmper helps you plan, comply, and manage risk across jurisdictions.

International tax rules rarely line up neatly across borders. A single decision — where to form an entity, how to structure a sale, where a family member resides — can create filing requirements and tax exposure in several countries. EisnerAmper works with clients across all industries and at every stage, from startups to multinational corporations, on both inbound and outbound tax matters.

Our objectives are straightforward: maximize planning opportunities, support compliance, reduce risk, and minimize tax exposure as the tax laws change and your own circumstances evolve.

Who We Work With

We organize our services differently for individuals and businesses because international tax touches each in a unique way — the rules, risks, and filings are not the same.

For Individuals

If you earn income abroad, hold foreign assets, or are moving to or from the U.S., the complexity of your filing requirements can expand quickly, and the penalties for noncompliance are significant. We help you preserve your wealth, protect your assets, and maintain compliance. 

For Businesses

If your business operates, sells, or invests across borders, every structural decision has tax implications. We help you plan transactions and implement structures that support your growth objectives while managing tax exposure in each jurisdiction.

International Tax Services

Our international tax team supports the full range of cross-border needs, from individual reporting obligations to the structuring of multinational operations:

  • Inbound and outbound tax planning and structuring
  • Inpatriate and expatriate tax planning and reporting
  • Pre-immigration and expatriation planning
  • Cross-border mergers, acquisitions, and divestitures
  • Foreign tax credit planning and utilization
  • Tax treaty planning and interpretation
  • Anti-deferral analysis and tax minimization (i.e., Subpart F, GILTI/NCTI)
  • Foreign asset and international information reporting
  • FATCA and withholding tax reporting and compliance
  • Cross-border gift, trust, and estate tax consulting and compliance

International Tax

We also have deep expertise in two critical areas of cross-border taxation:

Transfer Pricing

When related entities transact across borders, tax authorities expect arm’s-length pricing and scrutinize the documentation supporting it. We help organizations establish, support, and defend intercompany pricing for goods, services, financing, and intellectual property.

Coming to America

Our inbound and inpatriate tax services are specifically tailored to help foreign businesses and nonresident aliens navigate the distinct tax considerations of establishing a US presence, including entity choice, withholding tax rules, and federal, state, and local filing obligations. We help inbound clients plan their US entry and develop a clear path forward that will help maintain stability and compliance.

Our Approach

International tax work is most effective when it begins at the outset, before contracts are executed and entities are formed.

Our team takes a multi-phase approach, identifying opportunities and obstacles up front and adjusting as the tax rules and your own circumstances evolve.

Understand. We clarify your facts and objectives, map where income, people, and operations cross borders, and identify the jurisdictions and their applicable tax laws.

Plan and Model. We model effective tax outcomes under multiple scenarios, evaluate exposure to anti-deferral regimes and treaty pathways, and recommend a plan that is both efficient and defensible.

Implement. We translate the plan into action, coordinating any entity structuring and reporting obligations with your legal, finance, and operations teams.

Comply and Monitor. We manage ongoing deadlines for filings and disclosures and revisit your position as tax laws change and your circumstances evolve.

Why Early Planning Matters

Many international tax issues surface when options are limited, and remediation is costly — during an audit, an M&A due diligence request, or when a penalty notice is received. Properly scoping a client situation at the outset shapes everything downstream: structure, withholding, filings, transfer pricing, and audit defensibility.

Why EisnerAmper

  • One team, both directions. Inbound and outbound matters are handled together, so structuring, withholding, and reporting decisions remain aligned.
  • Individuals and businesses. We serve closely held businesses, multinational corporations, high-net-worth individuals (including their trusts and estates), and globally mobile executives, often within the same family or enterprise.
  • Global network. Through our membership in Allinial Global, we coordinate with advisors abroad to reconcile entity classification, residency, and documentation across jurisdictions.
  • Defensible, not just efficient. We build structures that are sustainable under IRS examination, with documentation and controls that reduce the risk of penalties.
