How much is the Form 5472 penalty?

Failure to file when required, or filing a substantially incomplete form, can result in a $25,000 penalty per form per tax year, subject to the applicable rules and circumstances.

Is the penalty charged automatically?

It is not assessed in every case. Whether a penalty applies, and whether relief is available, depends on the facts and the IRS's treatment of the particular case.

Does the penalty apply per year?

The amount is described per form per tax year, so multiple unfiled years can mean multiple exposures.

Do you prepare a reasonable cause letter for late Form 5472 filings?

Yes. If your Form 5472 filing is late, we review the circumstances and, when appropriate, prepare a reasonable cause statement at no additional charge. This also applies to eligible prior tax years.

Does the reasonable cause letter guarantee that the $25,000 penalty will be removed?

No. A reasonable cause statement does not guarantee penalty relief. The IRS makes the final determination based on the facts and circumstances of the case.

Is the reasonable cause statement included for prior-year filings?

Yes. For eligible late prior-year Form 5472 filings, preparation of a reasonable cause statement is included at no additional charge when appropriate.

What is reasonable cause?

A facts-and-circumstances standard under which a taxpayer who exercised ordinary business care and prudence but still could not comply may obtain relief. It is not a guaranteed outcome.

Can an incomplete form be penalised even though I filed?

Yes — the rules reach substantially incomplete filings, not only missing ones. Accuracy in the related-party and transaction detail matters.

Form 5472 Penalty

Form 5472 computes no tax, but the penalty attached to it is significant. Failure to file when required, or filing a substantially incomplete form, can result in a penalty of $25,000 per form per tax year, subject to the applicable rules and circumstances.

What triggers it

Not filing when a filing was required for the tax year
Filing after the applicable due date
Filing a form that is substantially incomplete
Not keeping the records the rules require

Because the amount is stated per form per tax year, an entity with several unfiled years can face exposure for each of them.

Continued failure after notice

Where a failure continues after the IRS notifies the taxpayer, the rules provide for additional amounts for each period the failure continues beyond the time allowed in that notice. Responding to IRS correspondence promptly is therefore materially different from leaving it.

Reasonable cause

Relief may be available where the taxpayer exercised ordinary business care and prudence and nevertheless could not comply. It is a facts-and-circumstances test decided by the IRS on the individual case, and it is not something to plan around in advance. Nothing on this page predicts how any particular request would be treated.

Filed late? We can help explain the circumstances.

If your Form 5472 filing is late, we review the circumstances and may prepare a reasonable cause statement to accompany the filing when appropriate. This service is included at no additional charge, including for eligible prior tax years.

A reasonable cause statement does not guarantee that the IRS will remove or reduce a penalty. The IRS makes the final determination based on the facts and circumstances.

More detail is in the late filing guide.

The common route to a penalty

Most exposure we see does not come from deliberate non-compliance. It comes from an owner believing that a dormant LLC, or one with no revenue, has nothing to file. The test is reportable transactions, not income — a point covered in the no-income guide. Formation costs paid personally, or funds moved into the LLC's account, can be enough.

If you are already late

Identify every tax year that may require a filing.
Gather the records for each year separately.
Prepare each year on that year's forms.
Submit rather than wait — exposure does not improve with time.
Take professional advice where a reasonable-cause position is being considered.

Note

Penalty amounts and procedures are set by the IRS and can change. Confirm current figures against the instructions and IRS guidance for the year concerned. This page is general information, not advice on your circumstances.
