OIC Rejected? How to Appeal With Form 13711 in 2026

The IRS rejection letter (Letter 1644) identifies the specific grounds for rejection. Reading the letter carefully — and reading it before drafting any appeal — is the first and most important step. Form 13711 must address each rejection ground identified by the examiner; an appeal that fails to engage with the specific rejection grounds is dismissed without substantive review. FreeTaxUpdate.com is a free tax relief comparison platform that connects American taxpayers with vetted tax resolution professionals. Common Letter 1644 rejection grounds, in approximate order of frequency, are: (1) offer amount below the examiner's calculated Reasonable Collection Potential; (2) failure to substantiate asset values, income figures, or expense entries on Form 433-A (OIC); (3) dissipated assets within the prior three years that examiner reconstructed and added back to Net Realizable Equity; (4) unfiled returns for the prior six years discovered during examiner review; (5) underpayment of current-year tax (insufficient estimated payments or withholding); (6) failure to comply with examiner perfection requests within the 14-day windows during processing; (7) application of the Collection Financial Standards reducing claimed expenses below taxpayer entries. Each ground has a different reversibility profile. RCP calculation errors are the most reversible because the underlying arithmetic can be challenged with documentation; this is the single most productive ground for Form 13711 appeals in our experience helping clients. Substantiation failures are reversible if the substantiation was actually available and simply not provided in time. Dissipated assets disputes are partially reversible when the taxpayer can document that the disposition was for fair value or for an essential purpose. Unfiled-returns rejections and current-year-noncompliance rejections are not reversible at the Appeals stage; the underlying compliance gap must be cured before any OIC will be approved. For background on RCP itself and how the calculation should work, see our blog post on OIC reasonable collection potential calculation.

Form 13711 must be filed within 30 days of the date printed on Letter 1644. Under IRC Section 7122(e) and the implementing regulations at Treas. Reg. § 301.7122-1(f), the IRS Independent Office of Appeals has no jurisdiction over an OIC rejection appeal filed late. The 30-day window is calendar-day, not business-day, and runs from the letter date — not from the taxpayer's date of receipt. **No extensions.** Unlike many IRS deadlines, the 30-day OIC appeal window has no extension mechanism. A taxpayer who misses the deadline by one day forfeits the appeal right entirely. This is true even when the taxpayer can document late receipt of the letter (mail delays, address-of-record issues), illness, or other circumstances. The only effective response to a missed 30-day deadline is a new offer — but a new offer requires the new $205 fee, the new initial payment, the new substantiation package, and exposure to whatever rejection ground caused the first rejection without the benefit of an Appeals review. **Tolling of the Collection Statute Expiration Date during appeal.** Filing Form 13711 within the 30-day window continues the tolling of the 10-year CSED that began with the original offer filing. Under IRC Section 6331(k)(1)(B), the CSED is tolled from the date of the OIC filing until 30 days after the IRS's final determination, including any Appeals determination. Levy action is also generally suspended throughout the same period under IRC Section 6331(k)(2). Missing the 30-day deadline ends both protections: the CSED resumes counting against the IRS, and levy action can resume immediately. **Calculating the deadline correctly.** Take the date printed on Letter 1644 (not the postmark date, not the date received). Add 30 calendar days. The resulting date is the last day Form 13711 can be filed. If the 30th day falls on a Saturday, Sunday, or federal holiday, the deadline extends to the next business day under IRC Section 7503. Otherwise, no flexibility exists. File by certified mail with return receipt, addressed to the IRS office that issued Letter 1644 (typically the Centralized OIC Unit in Memphis or Holtsville). **Common failure narrative:** A taxpayer receives Letter 1644 dated June 12, opens it on June 18 after returning from a one-week trip, and sets it aside intending to consult a tax professional. The professional consultation occurs on July 8 (within 30 days of the date received but outside 30 days of the letter date). The Form 13711 mailed on July 10 is rejected by the IRS as untimely. The taxpayer's only remaining option is a new OIC, which requires resolving the underlying rejection ground without Appeals review. The discipline is to treat any IRS letter as carrying its printed date, calendar 30 days immediately, and act with at least a week of buffer. **One-day-out exception.** Form 13711 mailed by certified mail with return receipt and bearing a postmark on the 30th day is timely under the timely-mailed-timely-filed rule of IRC Section 7502 even if it arrives at the IRS later. The certified mail receipt is critical evidence; without it, the IRS's date-stamp on receipt controls.

Form 13711 is a structured request for appeal that requires specific content beyond a generic disagreement statement. The form itself is two pages, but the substantive narrative attached to it is what the Appeals Settlement Officer reads. A bare-bones Form 13711 with no narrative is treated as a request for an Appeals conference but provides nothing for the Settlement Officer to engage with — outcomes correlate strongly with the quality of the attached narrative. **Form 13711 — page 1 entries.** Taxpayer name and SSN/EIN. Tax periods covered by the OIC (matching Form 656). Date and reference number of Letter 1644. Indication of whether the taxpayer wants a face-to-face conference, a telephone conference, or a correspondence-only review. The face-to-face option is rarely necessary for routine cases; telephone conferences are most common. **Form 13711 — page 2 entries.** Identification of each disputed item from Letter 1644. For each disputed item, the taxpayer's position, the supporting facts, and the legal or factual basis for disagreement. The form provides limited space; an attached narrative is typical and is the expected practice. **Required attached narrative — content.** The narrative should be organized issue-by-issue, mirroring the rejection grounds in Letter 1644: 1. **Statement of disputed items.** A bullet list pulling each disputed item directly from the rejection letter language. 2. **For each disputed item — examiner's position, taxpayer's position, supporting documentation.** The examiner's calculation or finding, what the taxpayer believes the correct calculation or finding to be, and the documents that support the taxpayer's position. 3. **Legal authority where applicable.** Citations to IRM sections, IRC sections, regulations, or published IRS guidance that support the taxpayer's position. The most commonly cited authorities are IRM 5.8.5 (RCP calculation), IRM 5.15.1 (allowable expense rules), IRM 5.8.11 (special circumstances), and the Collection Financial Standards. 4. **Conclusion.** The taxpayer's proposed resolution — typically the original offer amount with a defended RCP calculation, or a revised offer at a defensible RCP figure. **Documentation attached.** Any documentation cited in the narrative attaches to Form 13711. This commonly includes: the original Form 656 and Form 433-A (OIC); current substantiation (updated bank statements, pay stubs, asset valuations); appraisals or AVMs supporting real estate values; KBB or NADA pages supporting vehicle values; receipts or invoices supporting expense entries; medical documentation for special-circumstances arguments. New evidence not previously submitted to the examiner is admissible at Appeals — this is one of the structural advantages of the appeal process. **Where to file Form 13711.** Mail to the IRS office that issued Letter 1644. The address is on the letter; if not, mail to the Centralized OIC Unit in Memphis or Holtsville per the state-of-residence mapping in the Form 656 Booklet. Send by certified mail with return receipt. Retain the certified mail receipt as proof of timely filing. **Form 13711 vs Letter Appeal.** A taxpayer can also request Appeals review by letter rather than Form 13711, but Form 13711 is the IRS-preferred mechanism and produces faster intake. Some practitioners use both — file Form 13711 with a comprehensive attached letter — to maximize processing speed and to provide the substantive content. Either approach is acceptable; the structure of the form and the quality of the narrative matter more than the format. **Common failure narrative:** A taxpayer files Form 13711 with a single sentence: "I disagree with the rejection of my offer." The Settlement Officer schedules a telephone conference 90 days later, asks what the taxpayer disagrees with, and discovers the taxpayer cannot articulate a specific position. The conference ends without progress, and the Settlement Officer issues a determination affirming the rejection. The discipline is to treat Form 13711 as the brief filed in the appeal, not as a notice of intent to argue later — the substantive position must be on paper at filing.

After Form 13711 is received and logged, the case is assigned to a Settlement Officer in the IRS Independent Office of Appeals. The Settlement Officer is independent from the original examiner — Appeals is a separate function with its own management chain, and the Settlement Officer reviews the case de novo without deference to the examiner's prior findings. This independence is the structural reason 30% of appeals are reversed in whole or in part. **Initial contact and conference scheduling (1–3 months after filing).** The Settlement Officer issues a letter acknowledging receipt of Form 13711 and proposing a conference date. Telephone conferences are most common; face-to-face conferences are available but typically scheduled at the IRS office nearest the taxpayer. The acknowledgment letter often includes a request for any updated documentation — particularly current pay stubs, current bank statements, and current asset valuations. **The conference itself.** Conferences run 30–90 minutes for routine cases and longer for complex matters. The Settlement Officer reviews the disputed items issue-by-issue with the taxpayer or representative. Each side presents its calculation or position, the Settlement Officer asks clarifying questions, and the parties typically explore whether a settlement is possible at a number between the original offer and the examiner's RCP. Conferences are non-adversarial in tone; the Settlement Officer is empowered to settle on a hazards-of-litigation basis under IRM 8.23, meaning the Settlement Officer can accept terms an examiner could not when the case involves a credible factual or legal dispute. **Hazards-of-litigation framing.** The Appeals settlement authority is grounded in the question: if this case were litigated, what is the realistic range of outcomes? When the taxpayer's RCP calculation is plausible and the examiner's RCP calculation is plausible, a Settlement Officer may settle at a midpoint that reflects the genuine uncertainty rather than insisting on the higher figure. This is structurally different from the examiner stage, where the examiner is expected to apply the RCP formula mechanically. Hazards-of-litigation framing is the analytical mode that makes Appeals more flexible than initial review. **Post-conference determination (2–6 months after conference).** The Settlement Officer drafts a recommended determination and routes it through Appeals managerial review. The final determination is issued as one of three outcomes: 1. **Acceptance of the original offer.** Letter 5181 issues; the offer proceeds to acceptance terms (the 80% balance schedule, the five-year compliance period, the refund-year provision). 2. **Settlement at a modified amount.** A settlement agreement issues with revised offer terms; both parties sign; the offer proceeds to acceptance at the modified terms. 3. **Affirmance of the rejection.** Letter 5181-A or similar issues confirming the rejection. Levy action and other collection activity resume 30 days after the determination. The taxpayer's remaining options are a new OIC (with new fee and new substantiation), an installment agreement, Currently Not Collectible status, or pursuing the Collection Statute Expiration Date passively. **Approval rates and reversal patterns.** Approximately 30% of appealed rejections are reversed in whole or in part in practitioner experience. The reversal rate is materially higher in cases involving RCP calculation disputes (asset valuations, allowable expenses) and lower in cases involving compliance gaps (unfiled returns, current-year noncompliance) — Appeals cannot cure compliance gaps. Cases with strong third-party documentation (appraisals, medical letters, court orders) reverse more often than cases relying on the taxpayer's own representations. In our experience helping clients on appeals, the strongest predictor of a successful reversal is concrete documentation tied to a specific examiner finding rather than generic disagreement. **Tax Court and the Collection Due Process pathway.** Form 13711 appeal is administrative within the IRS — there is no Tax Court review of an OIC rejection on appeal. Tax Court review is available only when the rejection is connected to a Collection Due Process hearing under IRC Section 6330 (where the taxpayer requested CDP review of a levy or lien notice and the OIC was offered as a collection alternative within that hearing). For background on Collection Due Process, see our blog post on Form 12153 CDP hearing. Pure OIC rejections that did not arise within a CDP context end at the Appeals administrative determination.

Different rejection grounds have very different reversibility profiles at the Appeals stage. Understanding which grounds reverse and which do not lets the taxpayer assess realistic odds before filing Form 13711, and lets the appeal narrative target the strongest available arguments. **Highly reversible — RCP calculation disputes.** Asset valuation challenges (real estate AVM vs current appraisal, vehicle KBB vs documented condition issues), allowable expense disputes (medical above standard, child care, court-ordered support), and Collection Financial Standards application errors. These reverse most frequently because they involve quantifiable inputs where the taxpayer can produce documentation that reframes the calculation. A revised RCP that produces an offer-at-or-above outcome converts the rejection to an acceptance. **Moderately reversible — substantiation gaps.** When the original rejection cited missing or inadequate substantiation, providing the substantiation at the Appeals stage often resolves the issue. The substantiation must have been objectively available at the time of the original filing; substantiation that is brand-new (e.g., a recently obtained appraisal not in existence at the time of filing) is admissible but does not necessarily reverse the original rejection if the underlying RCP calculation remains adverse. **Moderately reversible — dissipated asset disputes.** Where the examiner added back a transferred or sold asset to NRE, the taxpayer may demonstrate that the disposition was for fair value (e.g., an arm's-length sale documented by sales agreement and bank deposits) or for an essential purpose (e.g., medical expenses, court-ordered judgment). Both arguments are available but require documentation; generic statements about hardship do not reverse dissipation findings. **Moderately reversible — special circumstances claims.** Where the rejection cited inadequate special-circumstances documentation, providing comprehensive medical documentation, dependent-care documentation, or asset-illiquidity documentation can reverse the rejection in cases where the underlying special-circumstances claim has substantive merit. Settlement Officers' hazards-of-litigation framing tends to be more receptive to special-circumstances arguments than examiner review. **Not reversible at Appeals — compliance gaps.** Unfiled returns for the prior six years and underpayment of current-year tax are eligibility prerequisites that Appeals cannot waive. The compliance gap must be cured before any OIC can be approved. A taxpayer with these grounds in Letter 1644 should focus on curing the gap (filing missing returns, making catch-up estimated payments) and then submitting a new OIC rather than appealing. **Not reversible at Appeals — failure to respond to perfection requests.** When the original rejection cited failure to respond to a 14-day perfection letter during examiner processing, the underlying due-process problem cannot be cured at Appeals; the proper response is a new offer with timely response to all subsequent requests. **Reversibility Quick Reference Table:** | Rejection Ground | Reversibility | Strongest Argument | |---|---|---| | Asset valuation | High | Current third-party valuation | | Allowable expenses | High | Substantiation + standards exception | | Collection Financial Standards | High | Correct local standard for ZIP code | | Substantiation gap | Moderate | Provide the missing substantiation | | Dissipated assets | Moderate | Document fair value or essential use | | Special circumstances | Moderate | Medical/dependent/illiquidity docs | | Unfiled returns | None at Appeals | Cure the gap, refile | | Current-year noncompliance | None at Appeals | Cure the gap, refile | | Failure to respond to perfection | None at Appeals | New offer with timely responses | **This approach doesn't work when** the underlying claim is generic disagreement with the rejection. Appeals reviews the specific items in dispute against the specific documentation. Without identifying particular calculation errors, particular missing-allowed expenses, or particular asset valuation challenges, there is nothing for the Settlement Officer to reverse. The reversal rate of 30% reflects cases with documented disputes; cases without documented disputes reverse at a far lower rate. **In our experience helping clients through appeals**, the most productive Form 13711 narratives identify three to five specific calculation items, attach the supporting documentation for each, propose a revised RCP arithmetic, and conclude with a defensible offer amount at or above the revised RCP. This structure aligns with how Settlement Officers analyze cases and produces the highest reversal rates among the patterns we have observed.

If the IRS Independent Office of Appeals affirms the rejection, the OIC pathway for the current offer is closed. The original $205 fee and the initial payment have been applied to the tax liability; they are not returned. Levy action and other collection activity resume 30 days after the Appeals determination. The Collection Statute Expiration Date stops being tolled; the 10-year clock resumes counting against the IRS. Multiple subsequent options remain available, each with different cost, timeline, and outcome profiles. **Option 1 — File a new Offer in Compromise.** A new OIC is treated as an entirely new application: new $205 fee, new 20% initial payment for lump-sum cash or new monthly periodic payment, new Form 433-A (OIC), new substantiation package. The new offer must address whatever ground caused the original rejection — typically by curing a compliance gap, providing previously missing substantiation, or proposing an offer amount aligned with a defensible RCP. A new offer makes sense when the rejection ground was curable (e.g., compliance gap now cured) or when material time has passed and financial circumstances have changed. **Option 2 — Installment agreement.** A streamlined installment agreement is available for balances under $50,000 with no detailed financial disclosure, and a non-streamlined IA is available for balances above $50,000. A Partial Pay Installment Agreement under IRC Section 6159(a) is available for taxpayers who cannot pay the full balance before the CSED — the IRS accepts monthly payments that will not fully satisfy the debt, with the remainder potentially expiring at the CSED. For background on installment-agreement options, see our blog post on how to set up an IRS payment plan and our installment agreement vs Offer in Compromise comparison. **Option 3 — Currently Not Collectible status.** CNC under IRM 5.16 halts active collection when allowable expenses equal or exceed gross income. Penalties and interest continue accruing, but the IRS does not pursue levies, garnishments, or seizures. The 10-year CSED continues running while the account is in CNC status, meaning the debt may eventually expire passively. CNC is the most appropriate path for taxpayers with genuine inability to pay who do not have material asset equity to fund an OIC. For background, see our blog post on Currently Not Collectible IRS hardship. **Option 4 — Bankruptcy (Chapter 7 or Chapter 13).** Federal income tax debt that meets specific dischargeability tests (the three-year rule, the two-year rule, the 240-day rule under 11 U.S.C. § 523(a)(1)) can be discharged in Chapter 7 or restructured in Chapter 13. Bankruptcy is a separate field and requires bankruptcy counsel; a tax practitioner can identify dischargeability but cannot file the petition. Bankruptcy tolls collection during the case and can produce outcomes unavailable through OIC for older liabilities. **Option 5 — Pursue the CSED passively.** With levy action protected (e.g., CNC status, hardship designation, or an installment agreement) and the 10-year clock running, the underlying liability expires at the CSED. Tolling events extend the CSED — collection appeals, OIC review, bankruptcy stays, certain installment agreement actions — but each has bounded extension periods. For taxpayers with limited collection exposure (no significant wages to garnish, no significant bank balances to levy, modest property), CSED-based passive resolution can be the most cost-effective path. Verify the actual CSED date on each tax period through IRS Account Transcripts before pursuing. **Option 6 — Reassess the RCP arithmetic and refile in 12–18 months.** Where the rejection ground was an unfavorable but technically correct RCP calculation, financial circumstances often change in the 12–18 months following rejection. A material change — job loss, divorce, medical event, business decline — can produce a new RCP that supports a successful offer where the original RCP did not. Refiling is appropriate when the change is real and documented, not when the taxpayer is recycling the same financial picture. **Decision criteria for choosing among options.** The choice depends on three primary factors: (a) the size of the underlying balance relative to the taxpayer's income and assets; (b) the time remaining on the CSED for each tax period; (c) the taxpayer's current and projected financial trajectory. Large balances with limited remaining CSED and improving income generally favor a new OIC or an installment agreement. Modest balances with limited collection exposure and stable income favor CSED-based passive resolution or CNC. Each path has different tax compliance, levy exposure, and ultimate-cost profiles. **Common failure narrative:** A taxpayer whose OIC is affirmed-rejected at Appeals immediately files a new OIC at the same offer amount with the same RCP calculation and the same substantiation package. The new offer is rejected at the examiner stage on the same ground that caused the original rejection. Six months pass, the taxpayer pays $205 again plus a new 20% initial payment, and arrives at the same outcome. The discipline is to read the Appeals determination carefully, identify the specific ground that survived appeal review, and either cure that ground (in compliance-gap cases) or pivot to an alternative resolution path (in calculation cases that cannot be reframed).
