Do I need a tax professional to file an Offer in Compromise?

While you can file an OIC yourself, the statistics strongly favor professional representation. The IRS overall acceptance rate for OICs is approximately 30-40%, but experienced tax professionals report higher success rates because they: properly calculate the Reasonable Collection Potential (RCP) to determine if an OIC is viable before investing time and money, maximize allowable expenses using IRS National and Local Standards, accurately value assets to minimize the offer amount, know how to address IRS objections and navigate the process, avoid common mistakes that result in return or rejection (like incomplete forms or insufficient documentation), and handle the appeal process if initially rejected. Common DIY mistakes include: offering too little (resulting in rejection), offering too much (paying more than necessary), failing to include all required forms and documentation, not making estimated tax payments while the OIC is pending (which causes the IRS to return it), and incorrect financial calculations. The $205 application fee and 20% initial payment are non-refundable if the OIC is rejected, so ensuring viability before applying saves money. A professional consultation ($200-$500) to assess OIC viability is a worthwhile investment before committing to the full process.
