After a penalty notice arrives, importers hear two pieces of advice that sound like the same thing: “file a petition” and “make an offer.” They are not the same thing. A petition for mitigation and an offer in compromise rest on different statutes, ask CBP different questions, require different disclosures, and succeed or fail for different reasons. Choosing the wrong one — or worse, treating them as interchangeable — wastes the response window on an argument that was never going to land.
The choice is genuinely strategic, and it usually comes down to a single question: are you disputing the amount, or your ability to pay it? This article lays out what each tool actually does, when each fits, what the offer in compromise demands that the petition does not, and how the two sequence together.
Two Tools, Two Questions
A petition for mitigation, brought under 19 U.S.C. 1618, asks CBP to reduce a penalty on the merits. Its argument is: given the facts and the mitigating factors, this amount is too high. It is the default response to most penalty and liquidated-damages notices, and it is decided by the Fines, Penalties & Forfeitures office against CBP’s published guidelines.
An offer in compromise, brought under 19 U.S.C. 1617, asks CBP to accept a lump sum in full settlement of the claim. Its argument is one of two things: either there is real doubt CBP could actually establish liability (doubt as to liability), or the debtor genuinely cannot pay the full amount (doubt as to collectibility). It is a settlement instrument, not a merits argument, and it is evaluated very differently.
| Petition for Mitigation | Offer in Compromise | |
|---|---|---|
| Statute | 19 U.S.C. 1618 | 19 U.S.C. 1617 |
| The ask | Reduce the penalty on the merits | Settle the whole claim for a lump sum |
| Grounds | Mitigating factors; the amount is excessive for the conduct | Doubt as to liability, or doubt as to collectibility (inability to pay) |
| Financial disclosure | Generally not required | Required, and extensive, for a collectibility offer |
| Nature of relief | A reduced assessment you still contest or pay | A binding settlement that closes the matter on payment |
| Best when | You dispute the amount but could pay a fair figure | You cannot pay a fair figure, or liability itself is genuinely doubtful |
When Each One Fits
Reach for the petition when…
- You believe the assessed amount is too high for the conduct
- You have documented mitigating factors — good record, cooperation, remedial action
- The violation was isolated rather than systemic
- You can pay a fair, reduced figure once you get there
- You want to preserve every argument before settling anything
Reach for the offer when…
- Even a mitigated amount exceeds what you can realistically pay
- Paying in full would threaten the viability of the business
- There is genuine legal doubt CBP could establish liability
- You want certainty and finality over continued dispute
- A petition has already run its course and the number is still unpayable
The cleanest way to see the difference: a petition is the right tool when your problem is the amount, and an offer is the right tool when your problem is the payment. If you could comfortably pay a fair reduction, you want a petition. If no fair reduction is payable, or if CBP’s ability to prove the claim is genuinely shaky, you are in offer territory.
What a Collectibility Offer Demands: Opening Your Books
The offer in compromise carries a cost the petition does not. To argue that you cannot pay, you must prove it — and that means giving CBP a detailed picture of your finances. A collectibility offer typically requires disclosure of assets and liabilities, income and cash flow, bank records, and business financial statements, all supporting the position that the offered sum is the most the government can realistically recover.
A collectibility offer is an audit you volunteer for
The financial disclosure required to support an inability-to-pay offer is thorough, and it is submitted to the same agency that is pursuing you. An offer that undercuts what your own financials show you can pay is not credible and will be rejected; an offer that reveals more capacity than you claimed can undermine your position.
The disclosure also has to be honest and complete — misrepresenting your finances to obtain a compromise is its own serious problem. This is not a form to fill out casually.
A doubt-as-to-liability offer is different in character. It does not require the financial disclosure, because the argument is legal rather than financial: that CBP would struggle to establish the violation or the amount if the matter were litigated. These offers turn on the strength of the government’s case, and they overlap with the analysis behind a protest or a defense on the merits. Our overview of the offer in compromise covers both bases in more detail.
Timing and Sequence
The two tools are not mutually exclusive, and in many cases the smart play is to use them in order. A common sequence is to petition first — pressing every mitigating factor to drive the number down on the merits — and to hold the offer in compromise in reserve for a collectibility argument if the mitigated amount is still unpayable. Petitioning first preserves your merits arguments and often makes any eventual settlement smaller.
But sequence is fact-dependent. Where liability itself is genuinely doubtful, a doubt-as-to-liability offer may be the stronger opening move. Where the business is in real distress and a drawn-out petition would only add interest and uncertainty, moving toward settlement sooner can make sense. What does not change is that both tools are deadline-driven: the response window on your notice governs, and the extensive preparation an offer requires argues for starting early rather than late.
| Your situation | Likely first move |
|---|---|
| Amount too high, can pay a fair figure | Petition for mitigation, pressing documented factors |
| Even a fair figure is unpayable | Petition first to lower the number, then a collectibility offer if needed |
| Liability itself is genuinely doubtful | Consider a doubt-as-to-liability offer, or a protest on the merits |
| Business in acute distress | Move toward settlement sooner; weigh a collectibility offer earlier |
Because the choice turns on a candid read of both the strength of your case and the state of your finances, it is worth making with counsel rather than by instinct. A customs and international trade lawyer can weigh whether your problem is the amount or the payment, press the mitigating factors in a petition first, and turn to an offer only if and when it becomes the better instrument.

Frequently Asked Questions
What is the difference between a petition and an offer in compromise?
A petition for mitigation, under 19 U.S.C. 1618, asks CBP to reduce a penalty based on the merits and mitigating factors. An offer in compromise, under 19 U.S.C. 1617, asks CBP to settle the whole claim for a lump sum, based either on doubt as to liability or on an inability to pay. One disputes the amount; the other resolves it.
Do I have to disclose my finances to CBP?
Only for an offer in compromise based on inability to pay. A petition for mitigation generally does not require financial disclosure, and neither does an offer based on doubt as to liability. A collectibility offer, however, requires detailed and honest financial disclosure to support the position.
Should I file a petition or an offer first?
Often the petition first, to drive the amount down on the merits while preserving your arguments, holding an offer in reserve if the reduced figure is still unpayable. But where liability is genuinely doubtful or the business is in distress, a different sequence may be better. It depends on whether your core problem is the amount or the payment.
Petition, offer, or both?
The right path turns on whether you’re fighting the amount or the ability to pay it. A customs attorney can make that call and file the tool that actually fits.
