The IRS may accept an Offer in Compromise (OIC) if you are unable to pay your delinquent taxes in full, but certain conditions and criteria must be met. The IRS evaluates OICs based on three primary grounds:
To submit an OIC, you must use Form 656, Offer in Compromise, and include the required application fee and initial payment unless you qualify for a low-income exception. The submission must also be accompanied by a financial statement (Form 433-A (OIC) for individuals or Form 433-B (OIC) for businesses) to provide the IRS with detailed information about your financial situation.
The IRS has established guidelines and procedures for evaluating OICs, and an independent administrative review process is available if your offer is initially rejected. If the IRS does not reject your offer within 24 months, it is deemed accepted.
In summary, the IRS may accept an OIC if you meet the criteria for doubt as to collectibility, doubt as to liability, or effective tax administration, and you follow the proper submission procedures.
