Zero income doesn't mean zero IRS obligations. Even a dormant foreign-owned U.S. LLC can trigger a $25,000 penalty if registered agent fees, state fees, or owner payments go unreported on Form 5472. Here is why $49 software puts you at risk and what CPA preparation actually includes.

Every comparison of Form 5472 filing services recommends automated tools for simple or inactive LLCs. This recommendation is incorrect.

That is the difference between a $399 filing and a $25,000 penalty.

If you are a non-U.S. resident who owns a Delaware LLC, you have two separate annual obligations — the $300 Delaware franchise tax and the federal Form 5472 filing. Most foreign founders know about the state tax. Almost none know about the federal one until a $25,000 IRS penalty arrives.

Foreign-owned U.S. LLCs face federal filing obligations regardless of revenue, profitability, or business activity. This CPA guide covers Form 5472, pro forma Form 1120, Form 1065, the $25,000 penalty framework, and the most common compliance mistakes made by non-U.S. entrepreneurs.

Automated Form 5472 filing tools cost $30-50. CPA-prepared filing costs $399. But a substantially incomplete Form 5472 triggers the same $25,000 IRS penalty as no filing at all under IRC §6038A(d)(1). This guide explains exactly what automated software cannot do — and why missing one related party or one transaction can cost $25,000.

Missing even one Form 5472 when you have multiple foreign related parties triggers a separate $25,000 IRS penalty per form. This CPA guide covers how penalty exposure multiplies, real-world multi-party examples, and how to coordinate all required forms into a single IRS-ready filing package.

Identifying every foreign related party is the first step in Form 5472 compliance — and the most commonly missed.

Every transaction between your U.S. entity and a foreign related party must be disclosed on Form 5472 — regardless of size, regardless of income.
