The problem

The IRS penalizes what you don’t know — and foreign owners pay the most.

Every US entity owes federal filings, and the right forms depend on your structure: a single-member LLC owner files differently than a C-corp or a partnership. Foreign-owned US companies face an extra layer — Form 5472 alongside Form 1120 — and the penalty for missing it starts at $25,000. Miss a deadline, misclassify your entity, or overlook deductions, and you either overpay or expose yourself to serious fines.

Doing the right thing shouldn’t require decoding the tax code.
