If you’re looking into an IRS Offer in Compromise, it’s easy to focus on the settlement number and overlook the process itself. That’s often where cases get into trouble. Many Offers in Compromise never make it to a true merits review because they’re returned as nonprocessable, rejected after financial analysis, or delayed by missing documents, compliance issues, or payment problems.
An Offer in Compromise, or OIC, is an agreement that may allow a taxpayer to settle tax debt for less than the full amount owed, but the IRS applies detailed eligibility, documentation, and compliance rules before an offer gets accepted. The IRS explains that taxpayers generally have to be current on required filings, estimated payments, and federal tax deposits, and an open bankruptcy case generally prevents the IRS from considering an offer at all. The agency also distinguishes between a return and a rejection: a rejected offer comes with appeal rights, while a returned offer generally does not.

In this post, you’ll learn seven of the most common OIC mistakes that lead to return, rejection, or delay, what those terms usually mean in practice, and where taxpayers often benefit from getting experienced legal help early. If you want a broader foundation first, it may help to start with this overview of how OIC settlements, financial disclosure, and acceptance risk usually work.

Before getting into the mistakes, it helps to separate three outcomes that many people lump together.
A returned offer often means the IRS decided it could not continue processing the submission, frequently because of eligibility, compliance, or procedural defects. The Taxpayer Advocate Service notes that the IRS can return an offer if it does not meet processability criteria, and the IRS’s internal guidance explains that return procedures apply when an offer is no longer processable or appears to have been submitted solely to delay collection.

A rejected offer usually means the IRS reviewed the case and concluded the amount offered did not reasonably reflect collection potential or the legal basis was otherwise not established. The IRS states that a rejection triggers written notice and appeal rights. Taxpayers generally have 30 days from the date on the rejection letter to request an appeal, often using Form 13711. IRS Internal Revenue Manual 8.23.1, IRS Tax Tip On Appealing A Rejected OIC, Form 13711
A delay can happen even when an offer is technically processable. Missing bank statements, vague asset values, inconsistent income figures, or unresolved filing issues can stretch the timeline and increase the odds of a bad result. Historically, government reports have found that delays can come from both taxpayer documentation problems and IRS inactivity. GAO-04-95, GAO-06-525
That distinction matters because the next move often depends on which bucket the case falls into.
One of the most common OIC mistakes is filing too early.
The IRS says taxpayers generally qualify for consideration only if they have filed all required tax returns, received a bill for at least one debt included in the offer, made all required estimated tax payments for the current year, and, if they operate a business with employees, made required federal tax deposits for the current quarter and the two preceding quarters. The IRS FAQs say the same thing in plain terms: required returns, estimated payments, and deposits all have to be current. IRS Topic No. 204, IRS OIC FAQs
This catches a lot of people because “I’m trying to fix it” and “I’m currently compliant” are not the same thing in OIC review. Someone may have old tax debt and a good reason for falling behind, but if current-year estimated payments are short or payroll deposits are missing, the offer can stall or be returned.
This issue shows up especially often with self-employed taxpayers and small business owners. A person may be focused on prior-year liability while the IRS is looking at current compliance first. In general terms, that often means the settlement discussion never really starts.
A tax attorney may be able to help identify whether the case is ripe for an OIC now, or whether another collection resolution path makes more sense while current compliance gets cleaned up.
Another common process failure involves the money that goes in with the offer.
For most doubt-as-to-collectibility OICs, the IRS requires an application fee plus an initial payment, unless an exception applies. Under current IRS guidance, low-income qualifying individual taxpayers can be exempt from the application fee and the required initial or periodic payments while the offer is under consideration. Offers based on doubt as to liability also follow different rules. IRS Internal Revenue Manual 8.23.1.5.1, IRS Form 656 Booklet, Taxpayer Advocate Service OIC Page
