Offer in Compromise Cost: IRS Fees + Rep Fees (2026)
Short answer: Expect two costs. The IRS charges a $205 application fee plus either a 20% deposit (lump sum) or your first monthly payment (periodic), both nonrefundable. Representation, if you hire it, runs roughly $1,500 to $10,000+. ASTR quotes a flat fee before work starts, after a free review.
Two different bills, and people confuse them
When someone asks "how much does an offer in compromise cost," they're usually asking about one of two completely different things: what the IRS itself charges to process the paperwork, or what it costs to pay someone to prepare and negotiate it for you. Both matter, and skipping either one is how people get surprised halfway through.
The IRS side is fixed and published. The representation side is a market, and it varies a lot depending on who you hire and how complicated your case is. We'll walk through both, then explain why we don't publish a flat number for our own fee on this page — and why that's actually a protection for you, not a dodge.
What the IRS charges: Form 656 fees
Every Offer in Compromise submitted on Form 656 carries a $205 application fee. That fee is paid once, with the application, and it is nonrefundable — if the IRS rejects or returns your offer, the fee is not returned to you; it's applied toward your tax debt instead.
On top of the fee, the IRS requires money up front depending on which payment option you choose:
Application fee — Lump Sum Cash offer: $205; Periodic Payment offer: $205
Money due with application — Lump Sum Cash offer: 20% of your offer amount; Periodic Payment offer: First proposed monthly payment
What happens while IRS reviews — Lump Sum Cash offer: Nothing further due until acceptance; Periodic Payment offer: Keep paying that monthly amount every month
Remaining balance paid over — Lump Sum Cash offer: 5 or fewer payments within 5 months of acceptance; Periodic Payment offer: 6 to 24 months after acceptance
Refundable if rejected? — Lump Sum Cash offer: No — fee and deposit are nonrefundable; applied to your balance unless you designate otherwise; Periodic Payment offer: No — same rule applies
Two exceptions are worth knowing. First, Form 656-L (Doubt as to Liability offers — you're disputing that you owe the tax at all, not whether you can pay it) does not carry the $205 fee. Second, the Low-Income Certification waives both the application fee and the upfront payment entirely if your household income is at or below 250% of the federal poverty guidelines, or you pass the AGI test tied to your most recent return. If you're a renter with modest income and no real assets, it's worth checking whether you qualify before assuming you need to pay anything up front at all.
One more structural point: the IRS doesn't let you guess. There's a free IRS Pre-Qualifier tool at irs.treasury.gov/oic_pre_qualifier that gives you a rough read on eligibility before you spend a dollar. It's not a substitute for the real math (we'll get to that in a different post), but it's a legitimate first filter.
What representation costs: the market, honestly
This is the part most sites either inflate to scare you or hide completely. Published fee ranges for OIC representation, by provider type, generally look like this:
National tax relief companies — Typical fee range: $3,000–$7,500+ (commonly quoted); Notes: Often preceded by a separate "investigation" fee of roughly $250–$750 before any OIC work starts
Tax attorneys — Typical fee range: $5,000–$10,000+ (commonly quoted); Notes: Attorney rates generally price in litigation capability you may not need for a straightforward OIC
Enrolled Agents and CPAs — Typical fee range: $1,500–$5,000 (commonly quoted); Notes: EAs and CPAs specialize in the IRS administrative process itself, which is where almost all OIC work actually happens
Why the spread? Complexity is the biggest driver — a self-employed taxpayer with multiple income sources and a business entity takes longer to document than a single W-2 renter with no assets. Whether the case is Doubt as to Collectibility (the vast majority of offers), Doubt as to Liability, or Effective Tax Administration also changes the workload. And some of the gap is simply overhead: a national call-center operation and a solo attorney's office carry very different cost structures that get passed on to you.
Here's what we won't do on this page: tell you a number for what we personally charge. Every case is different enough — unfiled returns, multiple years, business entities, prior offers — that a single advertised price would either be wrong for your situation or padded to cover the worst case. What we do instead is quote a flat fee, in writing, before any work begins, once we've actually looked at your numbers. No hourly surprises, no change orders halfway through.
Book a free 15-minute tax review and we'll tell you, honestly, whether an offer is even worth pursuing before you spend anything on representation. A lot of people come to us assuming they need an OIC when a different program — an installment agreement, Currently Not Collectible status — actually fits their numbers better and costs them nothing extra to pursue.
Why "worth pursuing" comes before "what does it cost"
The real cost question isn't just the dollar figure — it's whether the offer has a chance of being accepted at all. The IRS evaluates every offer against your Reasonable Collection Potential (RCP): the equity in what you own plus what you could pay from future income. If your RCP is higher than what you're offering, the IRS will reject it regardless of how good your preparation is, and you'll have spent the fee, the deposit, and the representation cost for nothing.
That's the actual value a free review provides: a read on your RCP before you commit a dollar to either the IRS or a preparer. If the math doesn't support an offer, we'll tell you that directly, and we'll talk about what does fit — an installment agreement, Currently Not Collectible status, or in some cases simply waiting out the collection statute.
Working with an Enrolled Agent
An Enrolled Agent (EA) is licensed by the U.S. Treasury specifically to represent taxpayers before the IRS, and is bound by Circular 230, the Treasury regulations governing practice before the IRS. That license covers exactly the kind of administrative negotiation an OIC requires — financial disclosure, RCP calculation, and direct dealing with the IRS's Offer in Compromise unit — without the overhead that comes with attorney-level litigation pricing you likely don't need for a standard case.
Bottom line
The IRS side of an OIC has a fixed, published cost: the $205 fee plus either a 20% deposit or your first monthly payment, both nonrefundable, with a waiver available for low-income filers. The representation side is a real market with a wide range, and the honest answer to "what will it cost me" depends on your specific filing history, assets, and income — which is exactly what a free review is for.
Book a free 15-minute tax review before you pay anyone anything. We'll look at your numbers, tell you whether an offer is realistic, and quote a flat fee in writing if it is.
Frequently Asked Questions
Is the $205 OIC application fee refundable if my offer is rejected?
No. The fee is nonrefundable whether the IRS accepts, rejects, or returns your offer. If your offer is rejected or returned, the fee and any deposit you paid are applied toward your tax balance instead, unless you specifically designate otherwise on the form.
Do I have to pay the 20% deposit if I'm choosing the periodic payment option instead?
No. The 20% up-front deposit applies only to Lump Sum Cash offers. If you choose a Periodic Payment offer, you send your first proposed monthly payment with the application instead, then keep paying that amount every month while the IRS reviews your case.
Can I avoid all IRS fees entirely?
Yes, if you qualify for the Low-Income Certification — generally household income at or below 250% of the federal poverty guidelines, or passing the AGI test on your last return. In that case both the $205 fee and the upfront payment are waived.
Why won't ASTR just list a flat price for OIC representation on this page?
Because an honest flat fee depends on your actual case — number of years involved, whether returns are filed, whether you have a business entity, and how much documentation is needed. We quote that flat fee in writing after a free review, not before we've seen your numbers.
Is it worth paying for representation if my RCP is clearly too high for an offer to work?
Generally no, and we'll tell you that in the free review rather than take a fee for a case that's unlikely to succeed. In that situation an installment agreement or Currently Not Collectible status is often the better fit, and neither requires the OIC application costs at all.
