The short answer
Form 5472 + pro forma 1120, prepared, reviewed, and filed. form5472.online charges $547 for the same filing.
For any foreign-owned US single-member LLC. Not sure it applies? Message us — no charge to check.
One flat fee covers the entire filing a foreign-owned single-member LLC owes for the year. Here is exactly what you get — and exactly what is not tacked on afterward.
No add-ons, ever
Checkout takes a minute. Payment reserves your filing and unlocks a short, plain-English intake form — no accountant jargon.
Enter your LLC name, EIN, formation date and state, and the money that moved between you and the company this year. Upload anything you have; we tell you what's missing.
A specialist completes Form 5472 and the pro forma 1120, reviews it, files it the correct way, and sends written confirmation. You're done for the year.
Have these ready and the intake takes about five minutes. Missing something? Start anyway — we tell you exactly what’s outstanding and can help you get an EIN if you don’t have one yet.
LLC legal name & US address
Exactly as registered with the state and the IRS.
EIN (Employer Identification Number)
Required to file. No SSN needed — if you don't have an EIN, we'll guide you.
Formation date & state
The date your LLC was formed and the US state it was formed in.
Record of related-party money
Capital you put in, loans to or from the LLC, repayments, and any amounts you paid yourself.
The same Form 5472 filing costs $547 at form5472.online and is bundled into $1,999/year at doola and $999–$1,499/year at Firstbase. We charge a flat $299. See the full breakdown on the pricing page or check your exposure with the penalty calculator.
The flat $299 covers the most common Form 5472 case — a foreign-owned single-member LLC that the IRS treats as a disregarded entity. If any of these sounds like you, applying is the right next step.
You just formed and funded an LLC
Wiring money in to start the company is a capital contribution from you, the owner — a reportable transaction. That means your very first year almost certainly requires Form 5472, even with no revenue yet.
Your LLC earned nothing this year
Form 5472 is triggered by a transaction, not by profit. A dormant or zero-income LLC that was funded, or whose state fee you paid personally, still has a reportable transaction and must file. We handle that filing the same way.
You sell online to US customers from abroad
E-commerce and SaaS founders running a US LLC remotely still file Form 5472 for their owner transactions. We prepare the information return; if you also have US income tax questions, we'll point you to a qualified advisor.
You missed one or more prior years
Each unfiled year is a separate Form 5472 with its own $25,000 exposure. Catch-up filing for prior years is the action that stops the penalty compounding — we file each delinquent year for a flat fee.
You set up through doola, Firstbase, or Stripe Atlas
Your formation service is great at setup but charges far more for the annual filing. The same Form 5472 + pro forma 1120 we file is bundled into their $999–$1,999/year plans. You can file with us instead and keep everything else.
Form 5472 is unforgiving in a way most tax forms are not. The penalty is a flat $25,000 per form, per year, with no cap and no statute of limitations — and it applies to an honest mistake or a missed deadline just as much as to deliberate non-filing. The danger is rarely the fee; it is filing the form wrong: submitting Form 5472 without the required pro forma Form 1120, trying to e-file when a disregarded entity cannot, using an outdated revision, or missing April 15 without an extension. Any of those can be treated as a failure to file.
That is exactly what the flat $299 removes. A specialist who prepares Form 5472 every day identifies your related parties, assigns each transaction to the correct part of the form, attaches it to a correctly completed pro forma 1120, and files the package the only two ways the IRS accepts for a foreign-owned disregarded entity — certified mail to P.O. Box 149342, Austin, TX 78714-9342, or fax to 855-887-7737. You receive written confirmation and dated proof of filing, which is your defense if the IRS ever questions the filing date.
You are not trading accuracy for price. We deliberately price low and still review every return, because the goal is simple: get your Form 5472 filed correctly, on time, once a year, for a price that reflects the actual work — not a bundle of services you never asked for. If you are unsure whether you even need to file, the 60-second qualifier and the reportable transaction checker settle it in under a minute — and we’ll confirm your situation for free on WhatsApp before you pay anything.
Flat $299. Form 5472 and pro forma 1120, prepared, reviewed, and filed — most within 7 business days.
