Foreign LLC owners should compare total risk exposure, not just upfront price, when choosing a filing service
When a foreign national owns a U.S. LLC or C corporation, Form 5472 is not optional. The IRS requires it, the penalties are severe, and the filing rules are specific. Two services have emerged to serve this market: Form5472 Prep at $149 and Form5472.online at $448. The price gap is real. So is the difference in what you get.
This comparison covers what each service actually delivers, who stands behind the filing, and what foreign LLC owners and C corporation shareholders risk by choosing the lower-priced option.
WHAT FORM5472 PREP OFFERS AT $149
Form5472 Prep markets itself as an affordable, fast solution for foreign-owned LLCs. At $149 per tax year, the platform guides users through a questionnaire and generates a completed Form 5472. The form is produced by software. No licensed CPA reviews it before it leaves the platform.
That is not a criticism of the platform. It is a description of the product. Software-based tax preparation is legal and common. But Form 5472 is not a standard consumer tax form. It reports foreign transactions, related-party dealings, and disregarded entity activity to the IRS. Errors and omissions carry a $25,000 penalty per transaction.
IRS PENALTY WARNING
The IRS imposes a $25,000 penalty per missing or incomplete reportable transaction under IRC Section 6038A. A $149 software filing that misses one transaction can cost the foreign owner $25,000. That is a 167-to-1 loss ratio on money saved by skipping professional review.
WHAT FORM5472.ONLINE OFFERS AT $448
Form5472.online prepares and signs Form 5472 filings with a licensed CPA included in the base price. Returns are prepared by the tax team and signed by Arik Rozen, Head of Tax Filing, a licensed CPA holding Virginia License #025991. The CPA prepares and signs each filing before submission.
This matters for three reasons. First, a CPA-prepared and signed filing carries professional accountability. Second, a licensed CPA can identify reportable transactions that software questionnaires often miss. Third, if the IRS contacts the client, the CPA can respond on the client's behalf. Software cannot.

FREQUENTLY ASKED QUESTIONS
Is Form5472 Prep an IRS-approved filing service?
Form5472 Prep is a software platform that helps users prepare Form 5472. It is not a CPA firm and does not carry the IRS approval designation that comes with enrolled agent or CPA licensing. The platform generates a completed form but does not provide licensed professional preparation.
What happens if Form 5472 has an error?
The IRS imposes a $25,000 penalty for each missing or incomplete reportable transaction under IRC Section 6038A. Errors in the form, missing transactions, or incomplete disclosures each trigger the penalty independently. A single error on a $149 filing can result in a $25,000 assessment.
