Home » Resources » International Tax Compliance: 3 Things To Know When Going Global
August 17, 2026
Expanding a business across borders is one of the most exciting milestones a company can reach. It’s also one of the most complicated things a company can do from a tax perspective.
Whether you lead a U.S. business planning an international expansion, a foreign company entering the U.S. market, or engage in complex cross-border transactions, here’s what you need to know when going global.
With every new country you enter, you add to the number of governments that can impose a tax on your business. But the risks of noncompliance begin much closer to home: The IRS is far less forgiving of international tax missteps than you may expect.
Failing to file, filing late, or providing incomplete or wrong data on U.S. tax forms tied to foreign entities, accounts, and transactions can saddle you with penalties starting at $10,000 per form. Penalties climb even higher for continued noncompliance.
Unlike penalties for domestic filings, penalties on U.S. international tax filings can apply even when no additional tax is owed or when the failure was unintentional. That means a missed filing can turn into a costly problem.
That’s to say nothing of the penalties imposed by foreign tax authorities. As a global or soon-to-be-global taxpayer, you can avoid the threat of harsh penalties by undergoing an international tax health check: a proactive review of your entity structure, filings, and cross-border transactions to confirm reporting requirements are met. An international tax health check typically looks at these items:
Finding it during an IRS audit is a penalty-reduction conversation, but finding an issue during an international tax health check is merely a planning conversation. Given how quickly international reporting failures can compound, a regular checkup is one of the most cost-effective moves a growing global business can make.
Once you know you’re meeting your compliance obligations, the next step is to make sure you’re as tax efficient as you can be.
Tax optimization is about minimizing the amount of tax owed under current law. The process involves determining how income is taxed in each country where you do business and how those rules interact with U.S. tax rules.
Here’s what a U.S. international tax advisor will look at when optimizing your tax structure:
These factors, as well as others, work together to help you minimize your global tax obligations and repatriate more cash.
Compliance and structure aren’t the only things that change when you go global. Your workforce does, too.
Sending employees abroad, hiring internationally, and bringing foreign talent into the United States all trigger a separate set of tax questions. Each time you consider any of these actions, it’s worth a conversation with your U.S. international tax advisor to understand the tax implications.
Even small employment-related actions can have an outsized tax effect. For example, sending an employee to work abroad may inadvertently cause the company to have a taxable presence in that country due to permanent establishment rules.
Businesses that consider international tax strategy as part of their global mobility plans are in the best position to move people across borders without triggering unexpected tax and reporting obligations for the company or the employee.
