If you’re facing a federal investigation, your lawyer may have already used the term “proffer” or “reverse proffer.” You may have nodded along without fully understanding what’s at stake. That’s dangerous. A proffer can shorten your federal prison sentence—but it can also make things much worse.
Let’s walk through what a proffer is, the risks of getting it wrong, and what you can do now to avoid becoming another cautionary tale.
What Is a Proffer and Why Does It Matter?
A proffer agreement is a written deal between a defendant (or target of an investigation) and the federal government. It allows the defendant to share information with prosecutors under limited immunity. Think of it like this: you’re allowed to talk, and the government agrees—on paper—not to use your direct statements against you, as long as you don’t lie or omit material facts.
That sounds good in theory. But in practice, the rules are much stricter than most people realize. If you say something false, omit a key detail, or even misremember something important, prosecutors can:
- Bring new charges,
- Tear up your cooperation agreement.I’ve seen it happen.
My co-defendant, for example, started cooperating, violated the agreement, and ended up with a longer sentence than expected. The government gave him a chance, but he blew it.
The “Sprite and Fries” Problem: Why Omissions Matter
Most people don’t enter a proffer session intending to lie. But that doesn’t matter. Let’s use a simple analogy we shared in our webinar.
If I ask, “What did you have for lunch?” and you say “a cheeseburger,” you’ve told the truth. But if you also had fries and a Sprite and didn’t mention them, you’ve given a partial truth. To you, that may seem harmless. But to a federal prosecutor, it’s a red flag. It’s called lying by omission, and it can cost you your cooperation deal—and possibly lead to new charges.
If you’re going to meet with the government, you need to think like they do. They expect full disclosure. That means:
- Volunteering relevant details without being asked,
- Acknowledging what you can’t recall with clarity,
- Offering a timeline that matches other known facts.
Reverse Proffers: Why the Government May Want to Talk to You
A reverse proffer flips the script. Instead of you sharing information, the government shows you some of the evidence they’ve built against you. It’s not a negotiation—it’s a presentation. You sit quietly while prosecutors and agents walk you through:
- Emails
- Recordings
- Wire transfers
- Surveillance
- Testimony from cooperating witnesses
Their goal is simple: convince you to plead guilty or cooperate. We’ve seen people spend hundreds of thousands of dollars going through discovery, only to attend a reverse proffer and realize—too late—that the government already had the goods.
If you’re heading into a reverse proffer, ask yourself: What are you waiting for? If the government already knows everything, you may have missed your chance to cooperate. The people who cooperate early often get the best deals.
Timing Is Everything: When It’s Too Late to Cooperate
The DOJ doesn’t wait. If you’re not the first person in your case to cooperate, you may not get a shot at all. We had a client who wanted to cooperate but didn’t act quickly. By the time he was ready, the government had already flipped his co-defendants. He had nothing left to offer.
That’s a brutal truth: you may want to cooperate and still be too late.
When the government asks, “Is there anything you want to tell us?”—your answer may determine your future. If you wait, you’re betting that nothing else will come out, that your co-defendants won’t talk, that the FBI didn’t already talk to your business partners (I learned this the hard way).
That’s a bad bet.
Proffer Doesn’t Equal Immunity: Understand the Risks
It’s tempting to think a proffer is a get-out-of-jail-free card. It isn’t. Some people cooperate and still go to prison. As one retired FBI agent told us, he could count on one hand the number of people who avoided prison entirely through cooperation. Everyone else still went to prison—just for less time.
Here’s why:
- The government can use your statements to gather derivative evidence—they can follow your leads to new witnesses, records, or evidence.
- They can use your words to impeach you if you contradict yourself in court.
- If your story doesn’t add up, they can argue you wasted their time or misled them.
And here’s the kicker: you may not even know how much credit you’ll get until right before sentencing. Cooperation isn’t a straight line to leniency.
5K1.1: The Government’s Golden Ticket
A 5K1.1 letter is the government’s formal way of saying, “This person helped us.” It gives the judge legal authority to sentence you below the mandatory minimum. But you don’t control when or if the government files it. They do.
If your cooperation is deemed helpful, timely, and truthful, you might get a 5K1.1 letter. We’ve had clients avoid prison altogether. Others shaved years off their sentence. But we’ve also seen people cooperate for years and still get a year and a day, wondering whether it was worth it.
Before you cooperate, ask yourself: What are you really willing to do? Are you prepared to:
- Sit for hours of interviews?
- Wear a wire?
- Testify at trial?
- Deal with the emotional toll of keeping secrets from friends or family?
If not, think carefully. There’s more than one way to mitigate. Not everyone is built for cooperation.
Don’t Go In Blind: Prepare Like Your Future Depends on It—Because It Does
We’ve seen defendants succeed in a proffer and reverse proffer by:
- Preparing a detailed timeline of events,
- Practicing responses with their lawyer,
- Creating narrative videos or written statements in advance,
- Working through our proffer course and reviewing our Proffer Blog Series
One lawyer we work with regularly sliced and diced a video transcript from a client, handed it to the U.S. Attorney, and had them saying, “This is one of the most professional submissions we’ve ever seen.” Preparation matters.
The Real Consequences of Getting It Wrong
We’ve helped people who walked into a proffer session unprepared and left devastated:
- Proffer voided
- New charges filed
- No second chance
- Trust lost with prosecutors
Some weren’t dishonest—they were just sloppy. They forgot details. They seemed evasive. That’s all it takes for the government to move on to someone else.
If you can’t explain your story clearly—or if your memory contradicts the evidence—they will not call you back for that second meeting.
Practical Takeaway: What to Do Right Now
- Talk to your lawyer about whether a proffer or reverse proffer is coming—and what to expect.
- Read our proffer blog series for honest insights: Start Here
- Prepare your story—timeline, documents, financial records, emails.
- Practice your delivery. The government will judge your tone, attitude, and candor.
- Be honest—even when it’s uncomfortable. The fries and Sprite you leave out may be what sinks you.
Final Word: Don’t Wing It
I spent a year in federal prison. Our team has worked with thousands of white-collar defendants. I’ve seen proffers go well—and I’ve seen them destroy people.
If you’re proffering, reverse proffering, or even considering it, prepare properly.
