However, the IRS will send you a notice 30 days from the date of the notification to respond to the IRS requesting a reconsideration of the decision to return the offer. Processing times vary, but you can expect it to take at least six months for the IRS to decide whether to accept or reject your compromise offer (OIC). The process can take much longer if you have to challenge the examiner's findings or appeal your decision. It usually takes six to nine months for the IRS to respond to your offer in a commitment request.
Staff, funding and the time of year when the OIC is presented influence the time needed for the decision-making process. If more than two months have passed, you should check with the IRS to see how the process progresses. It's common for the IRS to take up to six months to make a decision. Some decisions may take longer than a year.
The answer is six to twelve months, on average, although it may be longer, depending on the complexity of the case. If an appeal is needed, add another six months. In most cases, it takes about six months for the IRS to decide whether to accept or reject your transaction offer. However, if you have to challenge or appeal your decision, the process may take much longer.
There are cases where the IRS doesn't even consider your offer as a transaction.
