Form 5472 Filing Services Compared: $79, $149 or $547?

Three ways to file Form 5472 for a foreign-owned US LLC, checked 24 October 2026: Snapfile at $79, where an AI system reviews the filing; Form5472 Prep at $149, where a tax accountant holding an IRS PTIN reviews it; and form5472.online at $448 to $547, which its page describes as CPA-prepared. Take the $79 tier for one straightforward year, and pay for a human review when the facts are not simple.

Every figure below was read off the provider's own page on 24 October 2026. Two of the three services are ours — Snapfile and Form5472 Prep are the same team — stated in the table and again further down, because a three-way comparison is worth nothing if you cannot tell which rows the author owns. If you already want a tax accountant on the filing, start your filing; our plans are on pricing.

For the wider field — a dated survey of filing services, software and formation-provider bundles — see our comparison guides. This post is narrower: three services, one recommendation.

What do the three Form 5472 filing services cost?

Prices checked 24 October 2026 on each provider's own page: snapfile.tax/pricing, and the form5472.online home page. Prices change, so read the provider's own page before you buy.

What is striking is how little the price changes the output. All three produce the same statutory package, because the IRS prescribes it: Form 5472 attached to a pro forma Form 1120. What changes across the $79 to $547 span is who looks at it first.

Who reviews the filing at each price?

Each provider describes its own review in its own words.

At $79, Snapfile's page offers an "AI system review for completeness and consistency" and says plainly that the tier "does not include a human tax professional": an automated check of required fields, honest about what it is not.

At $149, a tax accountant who holds an IRS PTIN reviews the package before submission, deciding whether what you described belongs where you put it. Form5472 Prep is not a CPA firm and does not give tax advice.

At $448 to $547, form5472.online's page states the return is "CPA-prepared, reviewed & signed" by a "U.S.-licensed CPA (verified)". We make no claim about their quality and have not used their service, and we have not verified those credentials — what follows is what their page says it offers.

When is the $79 AI-reviewed filing the right choice?

When you have one tax year, you know what moved between you and the LLC, and you are content with an automated check. That is a common situation: an LLC formed last year, a few owner contributions, registered-agent fees paid from the owner's card, no revenue. The $79 package still ends with a signed filing faxed to the Ogden PIN Unit and a timestamped receipt.

If that describes your year, $79 at Snapfile is a reasonable purchase and we would rather say so than win the order. Whether you want a person to look at your records before they are filed is your call, not ours.

What does the extra $70 buy?

One thing, plus three options the cheaper tier does not offer at any price. Be clear which is which: the $70 difference buys the human review. Express, catch-up years, an EIN and an ITIN are charged separately at the prices below.

A person decides the judgement calls. Owner loans, reimbursements, formation costs paid personally, a distribution that was really a repayment — classification questions a completeness check cannot answer. A substantially incomplete Form 5472 counts as a failure to file, which is why who reads it matters.

A deadline you can still meet. Express at $199 is ready for you to check and sign within 24 hours, 7 days a week. The clock stops at "ready to sign", because the fax goes out once you sign.

Catch-up years at +$99 each, deliberately well below the first-year fee. A reasonable-cause letter is included; no provider can promise the IRS will accept one.

The pieces that are missing. If the LLC has no EIN, that is $149; if the owner needs an ITIN, $349. Firms filing for several clients can use a partner account.

What that list is not is "cheapest". Snapfile at $79 undercuts us and you can verify it in one click. We think $149 is the best value of the three — a human review at roughly a third of form5472.online's all-in price — which is a different claim from being the lowest number on the page.

Do you need a CPA to file Form 5472?

Not as a requirement of the form. The IRS states it plainly: "Any tax professional with an IRS preparer tax identification number (PTIN) is authorized to prepare federal tax returns," while adding that "tax professionals have differing levels of skills, education and expertise" (IRS: understanding tax return preparer credentials).

Three facts follow, narrow on purpose:

1. Form 5472 is an information return about transactions between the LLC and its foreign owner. It reports what moved; it does not compute tax or take a position on the owner's tax liability.
2. The IRS requires a PTIN of anyone who prepares a federal return for compensation. It does not require a CPA licence for this form.
3. So a CPA licence is not something Form 5472 itself requires of a paid preparer. That is a statement about the form's requirements, not about what any preparer is worth: a PTIN permits paid preparation, it does not by itself establish expertise.

That is the whole argument, and it stops there. A CPA, an enrolled agent or an attorney can do things a PTIN-only preparer cannot, and those come up on other work: a treaty position, a Form 1040-NR or 1120-F, transfer pricing between related entities, an IRS examination, or anything where you need someone to speak for you. On that last point the IRS is unambiguous — enrolled agents, CPAs and attorneys "have unlimited representation rights before the IRS", while a PTIN-only preparer has no authority to represent clients before the IRS. If a notice or an examination is already in play, that difference matters more than the price gap discussed here.

Nothing here says you do not need a professional. It sets out what Form 5472 requires of a paid preparer, which is a narrower question than what you want looking at your records before they go to the IRS. If you file Form 5472 for other people, filing Form 5472 for clients without being a CPA covers the same rules from the preparer's side.

What does Form 5472 actually ask for?

This is the fastest way to judge what a $547 filing buys. Per the IRS instructions for Form 5472, the package is a pro forma Form 1120 with Form 5472 attached, and on that Form 1120 the only information required is the entity's name and address and items B and E on the first page, with "Foreign-owned U.S. DE" written across the top. Four items: the cover page is clerical.

The judgement lives in Form 5472 itself:

• Part I identifies the reporting corporation — the LLC. Factual.
• Part II reports the 25% foreign shareholder; for a foreign-owned disregarded entity, the owner. Factual.
• Part III identifies the related party in the reportable transactions. Factual.
• Part IV reports monetary transactions with a foreign related party, line by line. This is where a wrongly classified owner payment lands in the wrong row.
• Part V is the box a foreign-owned disregarded entity checks for any other transaction not already in Part IV: the instructions name amounts connected with formation, dissolution, acquisition and disposition, including contributions and distributions, described on an attached statement.
• Part VI covers nonmonetary or less-than-full-consideration transactions with a foreign related party, with a schedule describing each.

So the form is mostly identification, with the difficulty concentrated in Parts IV to VI: deciding what each movement of money was. That is a classification task on your own records, not an audit or a tax opinion — which is the work a reviewing tax accountant does on our Standard tier, and the work an automated check does not do. For the line-by-line route, see Form 5472: DIY vs hiring a preparer; for costs generally, Form 5472 filing cost.

Two constraints apply whoever prepares it. A foreign-owned disregarded entity cannot file Form 5472 electronically: the package goes by fax at 300 DPI or higher to 855-887-7737, or by mail to the IRS PIN Unit in Ogden, Utah. And a fax transmission receipt is evidence that the package was sent, not confirmation that the IRS accepted it.

Are Snapfile and Form5472 Prep the same team?

Yes — and it is worth saying twice. Snapfile is ours. Its $79 tier is Snapfile's own AI-reviewed workflow, operated by Horizons Furness LLC; its human-review tier at $149 is this service, and snapfile.tax says so in its own words: "Offered and fulfilled by Form5472Prep.com. You'll continue on their website."

Snapfile's page frames the choice as we have: "Choose Snapfile for fast preparation with an AI system review, or continue to Form5472Prep.com when you want a tax accountant to review the filing." Two of the three rows are therefore ours, which is why the $79 recommendation above is a recommendation rather than a concession. Only form5472.online is unrelated, and every figure and claim attributed to it is quoted from its own page.

Frequently asked questions

What is the cheapest of these three Form 5472 services?

Snapfile's $79 AI-reviewed filing, checked 24 October 2026 — the lowest published price of the three for one tax year. Preparing the free IRS forms yourself costs nothing but your time and your own fax or postage.

Is a CPA required to file Form 5472?

No. The IRS states that any tax professional holding a PTIN is authorized to prepare federal tax returns, and Form 5472 is an information return. A CPA, enrolled agent or attorney is worth paying for representation, treaty positions or an examination.

Why does Form5472 Prep cost more than $79?

A tax accountant who holds an IRS PTIN reviews the package before submission, rather than an automated completeness check. Express is ready for you to check and sign within 24 hours, 7 days a week.

Are Snapfile and Form5472 Prep related?

Yes. Snapfile is ours. Its $79 tier is Snapfile's own AI-reviewed workflow, operated by Horizons Furness LLC; its human-review tier is this service, and snapfile.tax states that tier is "Offered and fulfilled by Form5472Prep.com."

What does form5472.online charge for Form 5472?

Its page lists $399, plus $49 for "IRS submission + confirmation", stated as "Total if filed with the IRS: $448 (All-In)" and "With reportable activity: $547 (All-In Active)", read off its page on 24 October 2026.

Can a foreign-owned LLC file Form 5472 electronically?

No. A foreign-owned disregarded entity cannot file Form 5472 electronically. The pro forma Form 1120 with Form 5472 attached goes by fax at 300 DPI or higher to 855-887-7737, or by mail to the IRS PIN Unit in Ogden, Utah.

Does a fax receipt prove the IRS accepted the filing?

No. A timestamped transmission receipt shows that the package was sent and when. It is evidence of transmission, not an IRS acceptance notice. Keep it with your copy of the return.

The bottom line

One straightforward year and organised records: take the $79 AI-reviewed filing. A missed year, an owner loan you cannot confidently describe, a close deadline, or a preference for a person's judgement on the classification: the $149 human review is the better value, and you can start it here. The CPA-signed service its page describes is priced at $448 to $547, but the form does not require the credential — and if what you need is representation before the IRS, buy that from an enrolled agent, CPA or attorney, not from a filing fee.

The $25,000 penalty is why any of this is worth comparing. The IRS assesses it on a reporting corporation that fails to file Form 5472 when due and in the manner prescribed; a substantially incomplete form counts as a failure to file; and if the failure continues more than 90 days after IRS notification, a further $25,000 applies per related party per 30-day period. Against that, the gap between $79 and $547 is small.
