Offer in Compromise – Doubt as to Collectibility
Reference Guide
Understanding Doubt as to Collectibility
An Offer in Compromise based on doubt as to collectibility is a formal request to settle your entire tax debt for less money because the IRS agrees you cannot pay the full amount, now or in the future. The IRS calculates your reasonable collection potential, which represents the amount you could realistically pay, and compares it to your offer. If the IRS approves, the agreement becomes final, thereby resolving the remaining debt.
The IRS verification process is thorough, and incomplete or inaccurate information on the application can result in rejection. This guide focuses on what the IRS evaluates during a doubt as to collectibility offer.
Who Should Use This Guide
This guide applies to you if you owe unpaid federal income tax, self-employment tax, or employment tax, and you cannot pay the full debt even over time. Use this guide if your income is low, your assets are minimal, and your expenses are high; if the IRS has already assessed the debt and is pursuing collection, or you want to stop collection proactively; if you have stable financial records for the past few years; and if you are willing to provide full financial disclosure to the IRS.
This guide does not apply if your income is growing or changing rapidly. You cannot estimate future earnings reliability if you are still in an active audit or examination, if you are filing bankruptcy or considering it, if your debt is very recent and collection has not been formally pursued yet, or if you cannot honestly document your expenses and asset values.
What the IRS Evaluates
The IRS decision on your offer hinges on one calculation: Does your offer amount equal or exceed what the IRS believes you can realistically pay? The IRS focuses on your actual monthly income from all sources, your legitimate living expenses, and what assets you own that can be liquidated or have equity value.
Your leverage changes when a sudden job loss occurs, when a medical crisis increases expenses, or when you sell a major asset. These events may necessitate a recalculation and strengthen your case. Hiding income, overstating expenses, failing to report a bank account, or submitting financial statements that do not align with prior tax returns raises concerns and may result in the rejection of your application.
The IRS can use older financial data if you do not provide current documentation. Providing the most current financial information ensures an accurate evaluation of your situation.
Essential Documentation and Calculation Steps
1. Gather your actual tax debt amount from the IRS by contacting them or logging into your
IRS account online to confirm the exact balance, including penalties and interest. Write down the total.
2. Collect three months of recent bank statements and two months of recent pay stubs.
Ensure the numbers match your tax returns filed in prior years.
3. List every asset you own: car, house, retirement account, savings, and investment property. Include fair market value, which is what you could actually sell it for.
4. Calculate your average monthly household income from all sources. Include wages, self-employment income, rental income, Social Security, unemployment, child support, disability, and anything that comes in regularly.
5. Document your necessary monthly living expenses in writing. The IRS has specific standards for what constitutes necessary expenses: rent or mortgage, utilities, food, insurance, transportation, medical care, childcare, and court-ordered debt payments.
6. Identify any past-due debts, liens, or ongoing collection actions against you. If the IRS is levying your wages or bank account now, or if other creditors have liens, disclose these explicitly.
7. Determine your offer amount. Reasonable Collection Potential (RCP) equals the net
realizable equity in your assets plus your future income potential. For lump sum offers, future income equals monthly disposable income multiplied by 12 months. For periodic payment offers, multiply monthly disposable income by 24 months or the number of months remaining on the collection statute, if fewer. Your offer should reflect your reasonable collection potential.
8. Prepare Form 656 with the correct statement of grounds. Check the box labeled 'Doubt as to Collectibility.' Include a detailed narrative explaining why the collection is doubtful, using your financial data.
9. Attach Form 433-A for individuals or Form 433-B for businesses with exact numbers.
Provide actual documentation. Any discrepancy between this form and your tax return may result in the rejection of your return.
10. Submit your offer with the correct filing fee and initial payment. The application fee is
$205. For one-time payment offers, include 20 percent of the total offer amount with your application. For periodic payment offers, include the first payment with your application and continue making monthly payments while the IRS evaluates your offer. Low-income taxpayers may qualify for a waiver of the application fee and initial payment using the
Low-Income Certification worksheet in the Form 656 Booklet.
11. Understand the IRS timeline for investigation. Offer in Compromise processing typically takes six months or longer to complete. Under federal law, the IRS has 24 months from the date it receives your offer to make a decision. If the IRS does not issue a determination within 24 months, the offer is deemed accepted. During this time, the IRS may request additional financial documents, conduct asset searches, or verify income.
Respond within the stated deadline in each request letter.
12. Do not make major financial changes during the offer process without notifying the IRS.
If you get a job promotion, receive an inheritance, sell property, or incur major new debt, tell the IRS immediately.
13. If the IRS counters or rejects your offer, you have 30 days from the date of the rejection letter to file Form 13711 to request an appeal with the IRS Office of Appeals. Many offers are reconsidered on appeal after being initially rejected.
Common Mistakes to Avoid
- Listing income lower than what appears on your tax return raises questions. The IRS
compares your offer application directly to your prior years’ tax returns.
- Claiming high expenses without documentation weakens your case. The IRS only counts
expenses that are reasonable, necessary, and verifiable by bank statements, bills, or receipts.
- Failing to disclose a bank account, asset, or piece of property can result in the
application being rejected. The IRS conducts asset searches as part of its investigation into the offer. Full disclosure is required.
- Offering an amount that is significantly below your calculated reasonable collection
potential without a clear justification typically results in rejection or a counteroffer.
Offering close to your reasonable collection potential gives you room for negotiation.
- Failing to respond when the IRS requests additional information may result in your offer
being returned or withdrawn. When the IRS requests information, the request letter specifies the deadline. If you cannot meet the deadline, contact the IRS immediately to request an extension or clarify requirements.
- Continuing to owe other back taxes or missing current-year tax payments while the offer
is pending can result in the offer being denied or delayed. The IRS will not settle old debt while new debt is accumulating.
Statute and Collection Considerations
If you do not address a tax debt and do not pursue an offer, the IRS will continue standard collection procedures. Wage levies, bank account seizures, and property liens will proceed.
Interest on unpaid tax debt is calculated using the federal short-term rate plus three percentage points, compounded daily. The rate is set quarterly and changes based on current federal rates.
The IRS also assesses a failure-to-pay penalty of 0.5 percent per month on unpaid balances.
The Collection Statute Expiration Date is tolled while an Offer in Compromise is being processed, during any appeal period, and for 30 days after the offer is rejected or withdrawn.
This means the IRS gains additional time to collect the debt beyond the standard 10-year collection period.
If your offer is rejected, you may submit a new offer at any time if your financial circumstances change or if you can provide additional information to support a settlement. There is no mandatory waiting period between offer applications.
Actions That Improve Outcomes
File your offer before collection activity becomes severe, as the IRS is more flexible in the early stages of the process. Provide bank statements, recent pay stubs, rent receipts, and insurance bills that match your financial claims exactly. The IRS uses a detailed review to identify discrepancies.
If your income is unstable, please provide specific examples and dates to support your explanation. If you possess a significant asset that cannot be liquidated, kindly explain the reasons and provide supporting documentation. Transparency often leads to counteroffers rather than outright rejections.
Respond to every IRS request within the stated deadline. Every financial statement requires exact numbers, and every status change must be reported immediately.
When to Seek Professional Assistance
Seek professional help if your debt exceeds $50,000 or involves multiple tax years, as higher tax liabilities often require careful application of tax law and the tax code. You should also seek assistance if you have recently changed jobs, received a promotion, inherited money, or experienced other major income shifts that affect your tax assessment and available payment options.
Professional guidance becomes critical if the IRS has already issued a wage levy, bank levy, or tax lien notice, or if your financial situation includes self-employment income, rental properties, or business debts that complicate the development of a payment plan. You should also consult a tax professional if your prior offer was rejected and you want to pursue audit reconsideration, appeal the decision, request Currently Not Collectible status, or file a new request under updated circumstances.
