Important: There is no such thing as a dormant foreign-owned LLC for Form 5472 purposes. If your LLC has a registered agent — and it must by law — you have a reportable transaction. Every year. Regardless of business activity.
🛡️What Happens After You Order
After checkout we send you two emails:
-
The first confirms your order and asks you to review the details. The second requests the information we need to begin — owner details, company information, and financials if your entity had transactions during the year.
-
We then assign a licensed CPA as your dedicated account manager. That CPA prepares your filing from start to finish and stays in direct contact with you throughout the process.
-
Every client receives access to our secured client portal where you can chat directly with your CPA team, upload documents securely, review your completed tax returns, and e-sign everything digitally once you approve.
-
If additional information is needed at any point, your CPA will contact you promptly.
-
Important note about state fees: State annual report filing fees and franchise taxes are not included in the bundle price. These are government-imposed fees that vary by state and are charged at cost — no markup. If your state requires an annual report or franchise tax filing, we will confirm the exact amount before collecting it separately. You will never be charged a state fee without prior confirmation.

Frequently asked questions
What is Form 5472 and why does my Mercury LLC need it?
If you are a non-U.S. resident who owns a U.S. single-member LLC, the IRS requires you to file Form 5472 attached to a pro forma Form 1120 every year a transaction occurred between you and your LLC. The penalty for non-filing is $25,000 automatic — with no warning, no grace period, and no reduction for small companies or low activity.
Does my LLC need to file even if it had no income?
Almost certainly yes. The filing obligation is triggered by transactions between you and your LLC — not by income. The registered agent fee alone, paid personally from any account in any country, is a reportable transaction. Most "inactive" LLCs still have a filing obligation every year they exist.
How does the filing process work?
You complete a short questionnaire about your LLC and its transactions for the year. The CPA team reviews your answers, classifies your transactions correctly, prepares Form 5472 and the pro forma Form 1120, sends them to you for e-signature through the secure portal, and faxes the completed package directly to the IRS. You receive timestamp-confirmed proof of submission.
What if I have missed filings from prior years?
Form5472.online handles late filings and penalty removal. The penalty removal service prepares late returns using IRS DIIRSP procedures combined with a CPA-prepared Reasonable Cause abatement request for each missed year. Acting before receiving an IRS notice significantly increases abatement likelihood. Learn more about penalty removal →
How long does it take?
Standard turnaround is 10 business days from receipt of your completed questionnaire. Expedited 3-day turnaround is available for $199. Rush 24-hour turnaround is available for $299 — useful if you are approaching the April 15 or October 15 deadline.
