Why It Matters

The IRS doesn't wait.
Neither should you.

Most LATAM founders operating in the U.S. are filing incorrectly — or not filing at all. The window to fix your structure is the 3–6 months before your first U.S. tax event. After that, remediation costs multiply.

Our Approach

Tax compliance isn't a box to check — it's the foundation your U.S. business runs on.

We don't just file your returns. We understand your ownership structure, your intercompany flows, and your treaty position — then we build a compliance posture that protects you as you scale.

Every client gets a dedicated advisor who knows their structure, an active filing calendar, and a clear response protocol if the IRS ever makes contact.

FAQ

What cross-border founders ask most about taxes.

Do I need to file taxes in the U.S. if my company is foreign-owned? add
Yes — if your company is formed in the U.S. (LLC, C-Corp) or has U.S.-sourced income, you have federal and potentially state filing obligations regardless of where the owners live. Foreign-owned single-member LLCs, for example, must file Form 5472 with the IRS every year, even if they show zero profit. Failing to file carries a $25,000 per-form penalty. We assess your exact exposure in the first session.
What is Form 5472 and who needs to file it? add
Form 5472 is an IRS information return required from any U.S. corporation or disregarded entity that has a 25%+ foreign owner and conducts reportable transactions with related parties. That covers most LATAM founders who set up a U.S. LLC — even if the LLC has no employees and operates as a simple holding vehicle. The penalty for a missing or late Form 5472 is $25,000 per form, per year. We file this as part of our standard annual engagement.
Can I apply for an ITIN without a Social Security Number? add
Yes — an ITIN (Individual Taxpayer Identification Number) is specifically designed for individuals who are not eligible for a Social Security Number but have U.S. tax obligations. This includes foreign founders of U.S. entities, non-resident recipients of U.S.-sourced income, and dependents of U.S. taxpayers. We are authorized to assist with the ITIN application process through the IRS Certified Acceptance Agent program, which allows us to verify original identity documents without requiring you to mail your passport.
What's the difference between federal and state tax obligations? add
Federal obligations are administered by the IRS and apply uniformly across the country — this is where Form 5472, 1120-F, 1040-NR, and FBAR filings live. State obligations vary by jurisdiction: each state has its own income tax rate (some have none), franchise tax, sales tax nexus rules, and annual report requirements. You can trigger state filing obligations through economic nexus — meaning revenue thresholds — even if you have no physical presence in that state. With 50 different rule sets, multi-state compliance is one of the most common areas where LATAM founders fall behind. We track and file in every active state.
