Form 5472 Penalty in California: IRS $25,000 + FTB Form 568 & the $800 Tax

This is worth stating plainly at the outset, because it is the first thing people want to know and the answer is genuinely simple. The penalty comes from the Internal Revenue Code, which applies uniformly. A foreign-owned single-member LLC in Los Angeles and one in Cheyenne face the identical federal exposure: $25,000 per unfiled Form 5472, per tax year, with no maximum cap and no statute of limitations, plus an additional $25,000 for each 30-day period after the IRS issues a notice and the form stays unfiled.

The full federal mechanics — how the continuation penalty compounds, what counts as substantially incomplete, and why an unfiled information return never starts the assessment clock — are on the Form 5472 penalty page and apply here without modification.

So why does this page exist? Because for a California LLC, the federal penalty is only half of the exposure, and the half people ask about is rarely the half that catches them first.

The federal and state systems are genuinely independent here. The IRS does not collect the $800. The FTB does not assess the $25,000. Filing one correctly gives you no credit with the other, and a reasonable-cause request granted by one agency has no effect on the other’s determination.

The practical consequence: a founder who discovers the Form 5472 problem and fixes only that has resolved one of two problems, and usually not the one that will suspend their company.

This is the point that catches non-resident founders most often. They learn, correctly, that a foreign-owned single-member LLC is a disregarded entityand files no real federal income tax return — only the pro forma 1120 carrying Form 5472. They then reason, incorrectly, that the same must be true at state level.

It is not. California treats the LLC as an entity for its own purposes regardless of how the federal system classifies it. The LLC files Form 568 and pays the annual amount, and a single-member LLC does so even though the income itself passes through to the owner.

What Form 568 reports

• Identifying information for the LLC and its members, including the Secretary of State file number.
• The annual minimum franchise tax of $800, and whether it has been paid.
• Total California income, which determines whether an additional LLC fee applies on top of the $800 for higher-revenue LLCs.
• Member information, including for a single-member LLC whose sole member is a non-US person.

The due date for a calendar-year LLC is generally the 15th day of the third month after the close of the tax year, which is March 15 — a month before the federal April 15 Form 5472 deadline. Founders who anchor on April 15 have often already missed the state date.

Form 568 is a California filing and sits outside what we do. We prepare and file the federal Form 5472 with its pro forma 1120; for Form 568, engage a California tax professional.

The $800 surprises people in the same way the Form 5472 requirement surprises them, and for the same underlying reason: both are triggered by statusrather than by income. A founder who formed a California LLC in 2023, never used it, and assumed silence meant no obligation may have accrued several years of $800 amounts plus penalties and interest — alongside a federal Form 5472 exposure of $25,000 per year on the very same entity.

The parallel is worth internalising, because it also points to the fix. Both obligations continue for as long as the entity exists. If the LLC is genuinely not being used, ending the obligations means properly dissolving it and cancelling its registration — not simply abandoning it. An abandoned LLC keeps accruing on both sides.

For the federal side of a dormant entity, see whether a dormant LLC must file — the answer is usually yes, because funding it or paying its fees is itself a reportable transaction.

In practice this is the most common situation this page is written for: a non-resident who formed a California LLC, did not know about either obligation, and has now discovered both at once — usually because a notice arrived from one of them.

If you are writing a reasonable-cause request for the federal side, the penalty abatement letter template gives you the letter and three worked examples. It addresses the IRS only — a state request goes to the FTB under its own procedures.

The $25,000 is the bigger number, so it dominates the conversation. But a penalty is a debt, and a debt can be disputed, negotiated, and paid over time. Suspension is different in kind: it takes away the company’s capacity to act.

• You cannot enforce your own contracts. A suspended LLC cannot bring a lawsuit in California, so a customer who does not pay may simply not pay.
• You cannot defend one either. If you are sued while suspended, you cannot defend the action.
• The name becomes available. A suspended entity loses the exclusive right to its name in California.
• Banking and payment processors notice. Entity status is publicly checkable, and a suspended status can trigger account review.
• Revivor takes time. Restoring good standing means filing everything outstanding, paying the balance, and applying for revivor — not a same-day process.

This asymmetry is the practical argument for dealing with the state side first even though the federal number is larger. The IRS exposure, while severe, does not stop you operating tomorrow. Suspension does.

Step 3 is the one we handle. We prepare and file Form 5472 with the pro forma Form 1120 for a flat $299 per year, including prior years — see catch-up filing. Steps 4 and 6 are California filings and need a California tax professional.

This is the question most founders ask once they understand the state layer, and the honest answer has two halves.

On the federal side, state choice changes nothing. Form 5472 follows foreign ownership plus a reportable transaction. A Wyoming LLC, a Delaware LLC, and a California LLC with the same non-resident owner have exactly the same federal obligation and exactly the same $25,000 exposure.

On the state side, it depends on where you actually operate.California’s reach is based on doing business in California, not solely on where the entity was formed. An LLC formed in Wyoming but managed from California, with California staff or a California office, is generally required to register in California and owes the same Form 568 and $800. Choosing Wyoming genuinely helps only when there is no California connection to begin with — which, for a non-resident founder with no US presence, is often the case.

The trade-offs between states, including fees, privacy, and charging-order protection, are covered on the best state for a foreign-owned LLC. If the California entity is genuinely unused and you intend to wind it down, note that dissolution has to be done properly — abandoning it keeps both meters running.
