When a client cannot pay their federal tax liability in full, the practitioner's job is not to describe the four collection alternatives: it is to select the right one. That selection depends on a specific set of financial variables that most guides do not integrate into a single decision framework. This guide does.
This IRS collection alternatives practitioner guide is a strategic decision hub, not a deep procedural guide on any single tool. For the procedural details of each alternative, follow the links to the dedicated ATP guides. This guide covers: the first diagnostic questions that determine which alternatives are even worth analyzing, how the CSED window governs the framework, when each alternative produces the minimum total cost to the client, the Collection Financial Standards analysis that underlies most of the math, how to choose between PPIA and OIC when both are technically available, and the ongoing compliance obligations that determine whether any resolution holds.
All financial standards, program thresholds, and OIC acceptance criteria referenced in this guide must be verified at IRS.gov before applying them to a specific client matter. National and Local Standards change annually; this guide never states specific dollar amounts for Collection Financial Standards, because those amounts are updated by the IRS and must be pulled from the current IRS.gov standards table. This guide does not constitute legal or professional advice.
The Four Paths: CNC, IA, PPIA, and OIC
Before the decision framework, a brief definitional baseline. Each of the four paths is covered in a dedicated ATP guide; the links below connect to those resources for the procedural details this hub intentionally omits.
Currently Not Collectible (53X status)
CNC status is the IRS's formal recognition that a taxpayer cannot pay without economic hardship. The IRS suspends active collection (levy, seizure) while CNC is in place. The balance continues to accrue interest. The CSED continues running. The IRS reviews CNC status periodically. CNC is not a resolution; it is a delay. The delay can be strategically valuable if the CSED will expire before the client's financial situation improves enough to support a payment arrangement. See the complete installment agreements guide for the IA context and how CNC is positioned against it.
Installment Agreement (Standard)
A standard installment agreement is a payment plan in which the client pays the full balance (plus accrued interest and penalties) in monthly installments over a period that must end before or at the CSED. The IRS offers streamlined IA approval for balances under certain thresholds without requiring a full Form 433 financial analysis. For balances above the streamlined threshold, a financial analysis is required. See the installment agreements guide for the current streamlined threshold, the non-streamlined process, and the direct debit vs. payment options.
Partial Pay Installment Agreement
A PPIA is a payment plan in which the agreed monthly payment, at the client's disposable income level under Collection Financial Standards, will not satisfy the full balance before the CSED expires. The IRS accepts the partial payment arrangement; the unpaid balance expires with the CSED. A PPIA requires a full Form 433-A or Form 433-B financial analysis. See the Form 433-A/B financial analysis guide for how to complete the financial disclosure that supports a PPIA.
Offer in Compromise
An OIC is a negotiated settlement in which the IRS accepts an amount less than the full balance owed. The offer amount is based on the taxpayer's Reasonable Collection Potential (RCP): the sum of net realizable asset value plus present value of future income. An OIC is appropriate when the RCP is materially less than the full balance. The IRS does not accept OICs simply because a taxpayer cannot pay: the math must demonstrate that the offer equals or exceeds what the IRS could realistically collect. The IRS OIC Pre-Qualifier tool is a useful initial screen, but the pre-qualifier result is not a guarantee of acceptance; the IRS evaluates each submission individually. See the Offer in Compromise guide for the RCP calculation, Form 656 process, and OIC compliance requirements.
OIC ACCEPTANCE RATES: DO NOT STATE WITHOUT SOURCING
OIC acceptance rates are published in the IRS Data Book annually. This guide does not state a specific acceptance rate because the figures change year to year and citing an outdated rate misleads clients about their likelihood of success. The IRS OIC program does NOT "settle tax debts for pennies on the dollar" as a general matter: acceptance is based on the RCP calculation, not on a negotiated discount. Any advertising claim that implies a routine OIC discount is a regulated claim under Circular 230 Section 10.30. For current acceptance rate data, refer to the most recent IRS Data Book at IRS.gov.
The Practitioner's First Diagnostic: Ability to Pay, Willingness to Pay, and Asset Equity
Before running any analysis, three preliminary questions determine which alternatives are even on the table for a specific client.
Can the client pay anything at all?
Run a quick Collection Financial Standards analysis before anything else. Pull the current IRS National and Local Standards from IRS.gov (never use a memorized or prior-year figure), apply them to the client's household expenses, and compare the result to the client's gross monthly income. If disposable income after CFS-allowable expenses is zero or negative, the client may qualify for CNC status and may also have an OIC RCP calculation that produces a very low offer amount. If disposable income is positive, an IA or PPIA is the starting point, and OIC is a secondary analysis.
Does the client have significant asset equity?
Asset equity affects both the OIC RCP calculation and the CNC/PPIA eligibility analysis. A client with a free-and-clear home, significant investment accounts, or a business with equipment equity is not a CNC or low-RCP-OIC candidate even if current income is low. The OIC RCP includes the quick-sale value of assets (typically 80% of fair market value for real property) minus secured debt and applicable exemptions. A client with substantial equity in assets the IRS could theoretically levy must offer the net equity in any OIC, which may bring the OIC amount close to or above the total balance owed.
Is the client willing and able to comply going forward?
All four collection alternatives require ongoing filing and payment compliance. A client who has a persistent pattern of failing to file current returns or pay estimated taxes is at risk of defaulting on any resolution, regardless of how favorable the terms are. Before selecting and negotiating any alternative, the practitioner should have a frank conversation about what the client's compliance obligations will look like under each option and whether the client can realistically meet them.
The CSED Window as the Governing Variable: How Remaining Collection Time Determines the Framework
The Collection Statute Expiration Date is the most important variable in collection alternative selection, and it is also the one that practitioners most commonly fail to analyze before selecting a resolution path. See the CSED strategy guide for the full analysis of how to calculate, verify, and protect the CSED. For collection alternative selection, the governing principle is simple: the longer the CSED window, the more total payment the IRS can extract; the shorter the window, the more favorable alternatives like PPIA and OIC become.
Long CSED window (more than 7 years remaining)
With a long CSED window, the IRS has sufficient time to collect the full balance through a standard installment agreement if the client has adequate disposable income. A standard IA is typically the most appropriate and easiest-to-obtain resolution in this scenario. An OIC is still available if the RCP math supports it, but with a long CSED, the IRS's ability to collect over time means the RCP is relatively high, making the OIC offer amount potentially close to the full balance.
Medium CSED window (3 to 7 years remaining)
The middle range is where the PPIA vs. OIC comparison becomes most important. A PPIA will expire with the CSED; if the client's disposable income under CFS is modest, the total paid under a PPIA over 3 to 7 years may be less than an OIC offer amount. Run both calculations side by side: total projected PPIA payments vs. OIC RCP. The path that produces the lower total client cost is the one to pursue.
Short CSED window (under 3 years remaining)
With a short remaining CSED, both PPIA and CNC become highly favorable. CNC status, if the client qualifies financially, may result in the balance expiring before the IRS reassesses and removes CNC. A PPIA over a very short CSED window produces very low total payments. An OIC with a short CSED is also favorable on the income component (few months of disposable income to include in RCP), though assets still must be valued and included. Important caveat: submitting an OIC tolls (pauses) the CSED for the period the OIC is pending plus 30 days. Entering an IA also extends certain CSED protections. Verify the current tolling rules before choosing any alternative that may affect the CSED timeline.
When to Choose an Installment Agreement: Qualifying Criteria, Streamlined vs. Non-Streamlined, and the IA vs. PPIA Break-Even
A standard installment agreement is the right choice when the client can pay enough per month to satisfy the full balance (plus accrued interest) before the CSED expires, and when the balance qualifies for either streamlined processing or the client can support a non-streamlined application.
Streamlined IA: the fastest path for qualifying balances
For balances under the current IRS streamlined IA threshold (verify at IRS.gov; thresholds change), individual taxpayers can obtain an installment agreement without submitting a Form 433-A financial analysis. The IRS approves the IA based on the balance, the proposed payment amount, and current filing compliance. Streamlined IAs are approved faster and with less documentation burden than non-streamlined agreements.
Non-streamlined IA: when a 433-A is required
Balances above the streamlined threshold, or IA requests from clients with complex financial situations, require a full Form 433-A (Collection Information Statement for Wage Earners and Self-Employed) or Form 433-B (for businesses). The Form 433-A/B financial analysis guide covers how to complete the financial disclosure and how to use the Collection Financial Standards to support the proposed payment amount.
IA vs. PPIA break-even calculation
The break-even question is: at the client's CFS-determined disposable income, will the monthly payment satisfy the full balance before the CSED? If monthly disposable income times the remaining CSED months is greater than or equal to the total balance (with interest projection), a standard IA is achievable. If the product of disposable income times remaining CSED months is less than the balance, a PPIA or OIC is the appropriate alternative.
When to Choose PPIA: The CSED-Driven Case and How PPIA Beats OIC When RCP Exceeds CSED Capacity
A Partial Pay Installment Agreement is the practitioner's tool of choice when the client has some disposable income (too much for CNC, not enough for a full-pay IA) and the CSED window is short enough that the total PPIA payments will be less than an OIC RCP amount.
The PPIA math that beats OIC
An OIC RCP includes both the income component (monthly disposable income multiplied by 12 or 24 months) and the asset component (net realizable value of assets). A PPIA total is just the monthly payment times the remaining CSED months. If a client has significant asset equity that raises the OIC RCP above what a PPIA would collect over the CSED window, the PPIA is the better path for the client: less total payment, same end result (unpaid balance expires). Illustrative example (not a guarantee): a client with 40 months left on the CSED and $800/month in disposable income after CFS expenses would pay a projected $32,000 total under PPIA. If the OIC RCP is $40,000 due to home equity, PPIA saves the client a projected $8,000. These figures are illustrative only and depend on the specific facts of each case.
PPIA review requirement: re-evaluation every two years
The IRS reviews PPIA arrangements approximately every two years to assess whether the taxpayer's financial situation has improved. If the taxpayer's income has increased materially, the IRS may increase the monthly payment amount or transition the client from a PPIA to a full-pay IA. Advise clients entering PPIAs to plan for this review and to notify the practitioner if their income or asset situation changes materially during the PPIA period.
When to Choose OIC: RCP Calculation, the Pre-Qualifier Tool, and When the OIC Math Works
An Offer in Compromise is appropriate when the client's Reasonable Collection Potential is materially less than the full balance. The two scenarios where OIC math typically works are: (1) the client has very low income and minimal assets, so both the income component and the asset component of RCP are small; or (2) the CSED is long but the client has unusual circumstances (serious illness, age, business closure) that suppress future income in a way that makes the 12 or 24-month income projection in RCP unusually low.
The OIC Pre-Qualifier tool: use it, but do not stop there
The IRS OIC Pre-Qualifier tool at IRS.gov provides an initial indication of whether a client may qualify for an OIC and what a preliminary offer amount might look like. Use it as a first screen, not as a definitive determination. The pre-qualifier does not account for all asset categories, local expense variations, or special circumstances. A client the pre-qualifier says does not qualify may still have a valid OIC argument based on factors the automated tool cannot evaluate. A client the pre-qualifier says qualifies may have asset equity or income sources the tool did not capture. The pre-qualifier is a starting point, not an approval.
OIC Doubt as to Liability: a separate track
The standard OIC track is Doubt as to Collectibility (the RCP is less than the balance). A separate OIC track, Doubt as to Liability, is available when the taxpayer has a genuine legal dispute about whether the tax is owed at all, as in some cases where an SFR assessment is contested and audit reconsideration is not available. The Doubt as to Liability OIC is a distinct process and is not driven by the RCP calculation. See the non-filer resolution guide for the SFR context in which Doubt as to Liability OIC may be relevant.
When to Choose CNC: Hardship Analysis, 53X Designation, and When CNC Is a Bridge vs. an Endpoint
Currently Not Collectible status is appropriate when the Collection Financial Standards analysis shows that the client's allowable expenses under the current IRS CFS tables equal or exceed their gross monthly income, leaving no disposable income available for payment. CNC is not available simply because the client prefers not to pay; it requires a financial hardship showing supported by the CFS-based analysis.
CNC as a bridge to CSED expiration
CNC is most strategically valuable when the CSED is short and the client's financial hardship is likely to persist for the remainder of the collection window. If the CSED has two to three years remaining and the client's income is at or below the CFS allowable expense level, placing the account in CNC may allow the balance to expire without any additional collection action. This is not a guaranteed outcome: the IRS reviews CNC status and may remove it if the client's income improves. But for clients in genuine and persistent hardship with a short CSED, CNC is often the most favorable path.
CNC vs. OIC when both are technically available
A client who qualifies for CNC (no disposable income) also has a very low OIC RCP (income component near zero, assuming minimal assets). The choice between CNC and OIC in this scenario depends on: whether assets exist that would increase the OIC RCP; the length of the CSED; the client's desire for certainty (an accepted OIC provides finality; CNC does not); and the client's ability to meet the OIC compliance requirements (filing and payment compliance during and after the OIC period). For clients with very short CSEDs and no assets, CNC may be the simpler and lower-cost path to the same outcome as an OIC.
FTA DOES NOT APPLY TO CNC: PENALTY ABATEMENT IS A SEPARATE REQUEST
First Time Abatement (FTA) is a penalty reduction program; it is not a collection alternative and does not affect whether the underlying tax is collectible. CNC status does not include penalty abatement. If the client has accrued failure-to-pay or failure-to-file penalties that are inflating the balance, a separate penalty abatement request (using FTA eligibility or reasonable cause) should be filed concurrently with or prior to the CNC request. Abating penalties reduces the total balance, which may affect the collection alternative analysis.
ACS vs. Revenue Officer: How the Resolution Path Shifts When an RO Is Assigned
The IRS unit handling a case materially affects both the urgency and the procedure for collection alternative pursuit. Most collection accounts start with the Automated Collection System (ACS), a telephone-based unit that handles the earliest stages of the collection process. Revenue Officers (ROs) are field employees who are assigned cases that ACS has not resolved, typically larger balances, business cases, or situations that require in-person contact.
ACS cases: faster resolution through standard channels
For ACS cases, collection alternatives are typically requested through the Practitioner Priority Service line or through online account submission. ACS cases move faster than RO cases and have less individualized scrutiny of financial disclosures. Streamlined IA thresholds apply to ACS cases. A CDP hearing request (see the CDP hearing guide) is relevant if the client has received an LT11 notice; at that stage, the practitioner can request a collection hold while the CDP hearing is pending.
Revenue Officer cases: higher documentation standards
When a Revenue Officer is assigned, the case requires more thorough financial disclosure, faster response times, and direct communication with the assigned RO. RO cases almost always require a full Form 433-A or 433-B financial analysis for any collection alternative. The RO will verify income, bank statements, and asset values independently. For federal tax lien issues or IRS levy and seizure matters, the RO is typically the contact point, and resolving the immediate collection action is a prerequisite to any formal collection alternative discussion.
Collection Financial Standards: National Standards, Local Standards, and Using Actual vs. Standard Expenses
The Collection Financial Standards (CFS) are the IRS's allowable expense tables used to determine how much of a taxpayer's income is available to pay a tax liability after necessary living expenses. The CFS tables consist of National Standards (food, clothing, personal care, and other household items) and Local Standards (housing and utilities, transportation). Both are updated by the IRS and must be pulled from the current IRS.gov standards tables; this guide does not state specific dollar amounts for any CFS category because the amounts change and citing outdated figures harms practitioners and clients.
Actual vs. standard expenses: the practitioner's choice
For National Standards categories, the IRS generally allows the standard amount without requiring documentation, even if the taxpayer's actual expenses are lower. A taxpayer who spends less than the National Standard on food does not get a higher allowance for some other category to compensate. For housing and transportation (Local Standards), the IRS generally allows the lesser of actual expenses or the applicable Local Standard, except that for housing, if actual expenses exceed the Local Standard, the taxpayer may be allowed the actual amount in some cases if it is necessary to avoid homelessness or relocation. The Form 433-A/B financial analysis guide walks through how to apply the CFS analysis to the specific financial disclosure form.
CFS and the passport certification threshold
Clients with seriously delinquent tax debt may also be subject to passport certification under IRC 7345. The threshold for passport certification should be verified at IRS.gov (approximately $62,000 as of the date of this guide, adjusted periodically; verify current threshold before advising a client). Active collection alternatives (IA, PPIA, OIC pending) generally prevent or reverse passport certification. See the IRC 7345 passport certification guide for the certification mechanics and how collection alternatives affect passport status.
Switching Paths: How to Transition a Client From One Collection Alternative to Another
Resolution situations change. A client who was in CNC status may get a new job and now has enough income for an IA or OIC. A client in an IA may lose their job and need to transition to CNC or PPIA. A pending OIC may be rejected, requiring the practitioner to immediately file for an IA to prevent levy. The practitioner's ability to transition between alternatives without losing ground is part of the full resolution skill set.
CNC to IA: when income improves
If the IRS removes CNC status after a periodic review because the client's income has increased, the IRS will generally send a notice requesting payment or a collection alternative. At this point, if the client now has disposable income under CFS, file an IA application promptly. Do not wait for the IRS to initiate levy action; transition proactively when you know the client's income has improved materially.
IA to PPIA or CNC: when income drops
If a client in an IA loses income or incurs major expenses that make the agreed payment unaffordable, the practitioner can request a modification of the IA to reduce the payment amount (requiring a new financial analysis) or, if income has dropped below the CFS-allowable expense level, request transition to CNC. Do not let the client default on the IA without first requesting a modification; a defaulted IA can trigger immediate levy action.
OIC rejection: the 30-day appeal and the IA bridge
If an OIC is rejected, the taxpayer has 30 days to appeal the rejection through the OIC Appeals process. During the appeal, levy is generally suspended. If the appeal is also unsuccessful, the practitioner should have an IA application ready to file immediately upon conclusion of the appeal to prevent levy. Do not wait for the IRS to initiate collection after an OIC rejection; transition to an IA (or PPIA, if appropriate) before the next IRS contact.
Compliance Maintenance: Ongoing Filing and Payment Obligations for Each Active Resolution
All four collection alternatives share one requirement: the client must remain in current filing and payment compliance while the resolution is active. Filing current returns late, failing to make required estimated tax payments, or incurring new tax liabilities can default an IA, remove CNC status, invalidate a PPIA arrangement, or result in OIC revocation. The practitioner's role does not end at resolution approval; it includes monitoring the client's ongoing compliance through each filing season.
What "current compliance" means for each alternative
For an IA or PPIA: all returns due must be filed on time (or with extensions), and all current-year estimated tax payments must be made on time. Any new balance due that is not addressed through the existing IA (which covers only the years specified in the agreement) can cause default. For an OIC: full compliance is required for five years following OIC acceptance. For CNC: the client must file current returns; new balances due may cause the IRS to remove CNC status or add the new balance to the existing CNC account.
Linking the Resolution to the Return-Prep Workflow: How TaxWise Practitioners Use Each Tax Season to Maintain Compliance
For practitioners using TaxWise, the filing season is not just about preparing current returns: it is the annual compliance checkpoint for every client who is in an active collection resolution. A client in an IA, PPIA, OIC, or CNC arrangement needs their current-year return filed on time, their withholding or estimated payments verified, and their compliance status confirmed before the IRS's next review cycle.
Build a collection-client compliance checklist into your annual workflow: before preparing the current-year return, pull an Account Transcript to confirm the resolution is still active and in good standing, verify the client's estimated tax payments against the Form 1040-ES schedule, and calculate whether the refund or balance due on the current-year return will affect the resolution arrangement. A refund that the IRS offsets against the IA balance is generally not problematic, but a significant new balance due that cannot be folded into the existing IA requires prompt action before it triggers default. If you handle non-filer clients from the prior year whose SFR reversals are now processing, confirm the Account Transcript reflects the supersession and that the collection alternative negotiation can proceed. See the non-filer resolution guide for the SFR reversal workflow.
Regulatory Verification Notice

Frequently Asked Questions
What are the four main IRS collection alternatives and when is each appropriate?
The four primary alternatives are: (1) Currently Not Collectible (CNC/53X): when the client has no disposable income after IRS CFS-allowable expenses; (2) Installment Agreement: when the client can pay the full balance plus interest before the CSED expires in monthly installments; (3) Partial Pay Installment Agreement (PPIA): when the client can pay something but not enough to satisfy the full balance before the CSED expires; and (4) Offer in Compromise: when the client's Reasonable Collection Potential is less than the full balance owed. The right choice depends on the CSED window, the CFS analysis, and asset equity. Verify current IRS financial standards and program requirements at IRS.gov before applying any framework to a specific client.
How does the CSED window determine which collection alternative to use?
The CSED determines how much total payment the IRS can realistically extract. With a long CSED, a standard IA can satisfy the full balance over time. With a medium CSED, compare total PPIA payments vs. OIC RCP to find the lower-cost path. With a short CSED, CNC and PPIA become highly favorable because the remaining collection period is brief. Always verify the CSED from the Account Transcript before selecting a collection alternative, and verify any CSED tolling events (pending OIC, bankruptcy, CDP hearing) that may extend the collection window.
What is the OIC Reasonable Collection Potential (RCP) and how is it calculated?
RCP equals net realizable asset value (quick-sale value minus secured debt and applicable exemptions) plus the present value of future income available to the IRS (monthly disposable income after CFS expenses, multiplied by 12 or 24 months depending on payment structure). An OIC is appropriate when the total RCP is materially less than the full balance. Use the IRS OIC Pre-Qualifier tool as an initial screen, but not as a definitive result. Verify current CFS tables and RCP calculation methodology at IRS.gov before submitting an OIC.
Does First Time Abatement apply to CNC status?
No. First Time Abatement (FTA) is a penalty reduction program, not a collection alternative. CNC status suspends active IRS collection but does not abate any penalties. If the client has accrued failure-to-pay or failure-to-file penalties, those must be addressed separately through a penalty abatement request (FTA eligibility or reasonable cause), which is a distinct process from the CNC designation. Abating penalties reduces the total balance, which may improve the collection alternative analysis.
When does a PPIA beat an OIC for a client?
A PPIA beats an OIC when the total projected PPIA payments (monthly disposable income times remaining CSED months) is less than the OIC RCP. This most commonly occurs when the client has asset equity that raises the OIC RCP significantly but the CSED is short enough that the total PPIA payments will be smaller. Run a side-by-side comparison for each client: total projected PPIA payments vs. OIC RCP. The path with the lower total client cost is the one to pursue, adjusted for the client's willingness to meet the respective compliance and process requirements of each option.
