If you’re looking into an IRS Offer in Compromise, there’s a good chance you’re already dealing with pressure: back taxes, notices, payment problems, and uncertainty about what the IRS will actually accept. An Offer in Compromise, or OIC, can sometimes resolve tax debt for less than the full balance, but the process is document-heavy, detail-sensitive, and often slower than people expect.
In this post, you’ll learn 10 common reasons an IRS Offer in Compromise gets rejected or stalls, what the difference is between a return, a rejection, and a delay, and where applicants often run into trouble before the IRS ever reaches the merits of the offer. If you want a broader overview of how the program works, this guide on settling tax debt through the IRS compromise process gives helpful background before getting into these failure points.

The IRS describes an Offer in Compromise as an agreement that settles tax liabilities for less than the full amount owed when certain criteria are met. The agency’s current materials also make clear that not every application is even eligible to be considered, and many offers are returned instead of formally rejected because required filings, payments, or documents are missing. The official Form 656-B booklet, Topic No. 204, and the IRS’s OIC FAQs all point to the same pattern: a large share of problems come from process issues and financial disclosure issues, not just from the offer amount itself (IRS Form 656-B, IRS Topic No. 204, IRS OIC FAQs).
That distinction matters. A returned offer generally means the IRS did not fully consider it on the merits. A rejected offer usually means the IRS reviewed it and decided the taxpayer could pay more, the special circumstances were not sufficiently established, or the offer otherwise did not meet the standards for acceptance (IRS Topic No. 204, IRS Internal Revenue Manual 5.8.7).
One of the most common reasons an OIC gets returned is simple: missing tax returns.
The current 2025 version of the IRS Form 656-B booklet states that a taxpayer generally must have filed all required returns before applying, and it specifically notes that if the IRS determines required returns were not filed, the agency may apply the initial payment to the tax debt and return the offer. The same booklet includes a checklist asking whether all required tax returns have been filed and whether copies of very recently filed returns were included where required (IRS Form 656-B).
This is one of the reasons people sometimes think their offer was “denied,” when in practice the case never got to a substantive financial review. In general terms, the IRS tends to treat filing compliance as a gatekeeping issue.
OIC eligibility is not only about old debt. It also turns on whether the taxpayer is currently compliant.
The Form 656-B booklet states that applicants generally must make all required estimated tax payments for the current year. If the applicant is a business owner with employees, the booklet also says required federal tax deposits for the current quarter and the two preceding quarters must be current. The offer package requires the applicant to certify those items in writing (IRS Form 656-B).
That creates a frequent stall point for self-employed individuals and small businesses. Someone may be focused on old balances while current-quarter obligations keep accruing in the background. If the IRS sees ongoing noncompliance, the offer can be returned rather than carried through to a full decision (IRS Topic No. 204).
An OIC package is not just Form 656. Depending on the case, it may also involve Form 433-A(OIC), Form 433-B(OIC), bank records, pay stubs, expense proof, asset information, and other supporting material.
The IRS’s Form 656-B booklet says offers cannot be considered without completed and signed required forms and supporting documentation. The IRS Internal Revenue Manual also discusses returns when requested information is not provided, including situations where the taxpayer does not respond to requests for updated versions of forms or other missing items (IRS Form 656-B, IRM 5.8.7).
This is where many cases start to stall rather than end immediately. The IRS may ask for additional documents, updated statements, or clarification about expenses, transfers, or valuations. If the response is late, incomplete, or inconsistent, the file may sit, loop through follow-up requests, or be returned.
For people trying to avoid those problems, the financial disclosure side of the process is often where the most preventable damage happens. That’s also why related issues around documentation and disclosure tend to come up in discussions about preparing the forms without creating new tax problems.
