The compliance firm for foreign-owned US LLCs.

You opened a US LLC, and nobody told you about Form 5472. Not the formation company, not the registered agent, not the bank. We prepare and file it, together with the pro-forma 1120 cover return it rides on, and you approve everything before it goes.

Form 5472, handled.

from $250, with a fixed written quote before you commit to anything.

Start your intake

Would you rather talk first? Book a free 15-minute call.

A response within 30 minutes during business hours. US individuals and businesses are welcome too.

Two numbers explain this practice.

A missed Form 5472: the IRS penalty, per form, per year $25,000
Having it prepared and filed, fixed in writing from $250

The penalty applies even when the LLC earned nothing, and it can repeat for every year missed. The fix is a filing, and filing is our whole practice. Every price we publish is on the pricing page.

There is a route through this.

It is not a loophole and it is not a fight. Filing, late years included and with a properly argued reasonable cause statement, is the established way this is dealt with. Being behind is the most common way people arrive here. It changes the strategy, not the welcome.

Tell us where you stand

Five minutes of intake, or a free 15-minute call. No documents and nothing sensitive yet, just enough to scope the work. You get a response within 30 minutes during business hours.

See the price before anything starts

A fixed written quote covering everything your situation needs. No hourly meters, and nothing added later.

We prepare and file. You approve everything.

Your filings are prepared, reviewed with you, and submitted in under 3 days from a complete document set and cleared payment.

If you are years behind, start with the catch-up page. It walks through exactly how late filings and reasonable cause statements work, before you give anyone your details.

Reasonable price

I had a great experience with Caldwell Tax Services. Samuel was professional, responsive, and guided me through the entire filing process for my foreign-owned LLC. He answered my questions promptly, helped resolve every issue, and kept me updated until my documents were successfully submitted to the IRS. I highly recommend their services to anyone looking for reliable and knowledgeable tax assistance. Thank you, Samuel

Starting costs you nothing.

The intake is free, takes about five minutes, and asks for no documents and nothing sensitive. It commits you to nothing. What it gets you is a fixed written quote to say yes or no to.

Already holding an IRS notice? The 45-minute consultation is the right first step instead: $300, paid at booking, with $100 credited if you engage us within 15 days.

Questions foreign owners ask us every week.

Who has to file Form 5472?

Any US corporation that is 25%-or-more foreign-owned — and, since 2017, any foreign-owned single-member LLC treated as a disregarded entity. If you live outside the US and own a US LLC by yourself, this almost certainly means you. The form is filed together with a pro-forma Form 1120.

What happens if I don't file it?

The IRS penalty is $25,000 per required Form 5472, per year — and if it is still unfiled 90 days after the IRS notifies you, an additional $25,000 for each further 30-day period. It applies even if your LLC owed no tax. This single form is the reason our practice exists.

My LLC had no income this year. Do I still need to file?

Usually yes. Form 5472 reports "reportable transactions" with the foreign owner, not just income — and contributions you made to the LLC (formation costs, the registered-agent fee you paid, money you moved in) count. A dormant-looking LLC very often still has a filing obligation.

When is the deadline?

Form 5472 is due with the pro-forma 1120 by April 15 for calendar-year LLCs. A six-month extension to October 15 is available by filing Form 7004 — something we handle for every client who engages us near the deadline.

Do I need an FBAR too?

If the combined value of your non-US financial accounts exceeded $10,000 at any point in the year and you're a "US person" (which can include your US entity's obligations), FinCEN Form 114 applies. We assess this as part of every intake — it takes one question to check and a five-figure penalty to ignore.

I've already missed one or more years. Is it fixable?

Often, yes. Penalties can be contested through reasonable-cause abatement, and late filings are far better received when they arrive before an IRS notice does. Tell us in the intake form that you have missed filings — it changes the strategy, not our willingness to help.

General information, not tax advice for your specific situation. That's what the intake form starts. Unfamiliar terms are explained in the glossary.
