Building a business that operates internationally is one of the most exciting things an entrepreneur can do. It can also be one of the most expensive, in ways that have nothing to do with the market and everything to do with US tax compliance.
FATCA, the Foreign Account Tax Compliance Act, is a US law that has fundamentally changed how foreign banks and financial institutions interact with American account holders. Understanding what it requires and why it matters is not optional for US entrepreneurs with international financial activity. It is a baseline obligation with serious consequences attached.
What FATCA Actually Does
FATCA was enacted in 2010 and came into full effect in 2014. Its core mechanism is an information-sharing arrangement between the US government and financial institutions in over 110 countries. Foreign banks that want access to the US financial system must identify and report account holders who are US persons to the IRS, or face a significant withholding tax on US-sourced payments.
The practical result for entrepreneurs is that foreign banks and investment platforms are actively identifying US account holders and reporting account information to the IRS. If an entrepreneur has foreign accounts, foreign investment interests, or foreign business structures they have not properly disclosed, the IRS often knows before the entrepreneur has decided how to handle it.
FATCA created the infrastructure that makes non-disclosure increasingly difficult to sustain and increasingly risky to attempt.
The Reporting Obligation for Entrepreneurs: Form 8938
FATCA’s disclosure requirement for individual US persons is reported on Form 8938, filed with the federal tax return. The filing threshold varies based on residency and filing status.
For entrepreneurs living in the United States, the thresholds are:
- Single filers or married filing separately: $50,000 on the last day of the tax year, or $75,000 at any point during the year
- Married filing jointly: $100,000 on the last day of the year, or $150,000 at any point
For entrepreneurs living abroad, the thresholds are higher: $200,000 for single filers and $400,000 for married filing jointly at year end, with corresponding mid-year thresholds.
Form 8938 covers a broader range of assets than the FBAR, including foreign stocks, partnerships, interest in foreign entities, and financial accounts. Many entrepreneurs with foreign business structures have Form 8938 obligations they are not aware of.
Why Entrepreneurs Face Higher Exposure Than Employees
Entrepreneurs operating internationally carry FATCA risk in ways that salaried employees typically do not. The structures common in international business, including foreign holding companies, offshore investment vehicles, business accounts in multiple jurisdictions, and cross-border partnership interests, all create disclosure obligations that compound quickly.
An entrepreneur who has incorporated a foreign entity, holds a business account abroad, and maintains investment accounts in the same country may be looking at FATCA obligations, FBAR obligations, and potentially Controlled Foreign Corporation reporting all from a single international business structure. Each of these has its own form, its own threshold, and its own penalty schedule.
Missing any one of them is not just a paperwork oversight. It is a compliance failure that the IRS can pursue retroactively across multiple years.
Getting Compliant Before the Problem Surfaces
The IRS has established voluntary disclosure programs that allow taxpayers with unreported foreign financial interests to come into compliance with substantially reduced penalties, provided they act before the IRS initiates contact. The Streamlined Filing Compliance Procedures are specifically designed for taxpayers whose failures were non-willful.
Acting proactively through these programs is significantly more favorable than waiting until an audit or inquiry makes the choice unavoidable.
For entrepreneurs navigating the intersection of international business and US tax compliance, working with specialists who understand both FATCA and the broader picture of expat and international tax obligations is the most efficient path to a defensible position.
Based on resources from MyExpatTaxes, the most common entrepreneur mistake is treating FATCA compliance as a one-time disclosure when it is actually an annual obligation that requires review as business structures evolve.
The Penalty Structure Is Not Forgiving
FATCA penalties for failure to file Form 8938 start at $10,000 per violation and can reach $50,000 if the failure continues after IRS notification. In cases involving undisclosed accounts used to hide taxable income, additional civil and criminal penalties apply.
The statute of limitations for FATCA-related tax underpayments is also extended to six years, compared to three years for standard tax issues. This means a disclosure failure can be pursued significantly further back in time than most taxpayers expect.
For entrepreneurs who have not been consistently compliant, the penalty exposure across multiple years can dwarf the original tax liability that triggered the obligation.
Conclusion
The cleanest approach for any US entrepreneur operating internationally is to build FATCA compliance into the business structure from the start, rather than retrofitting it after the fact. This means understanding the disclosure implications of each foreign entity or account before it is established, rather than discovering them at tax time.
Entrepreneurs who treat international tax compliance as a structural consideration rather than an annual filing exercise protect themselves from the most serious exposures and maintain the flexibility to operate globally without creating compliance liabilities that follow the business indefinitely.
