When a client owes a balance they cannot pay in full, an IRS installment agreement is usually the most straightforward path to resolution. For a tax preparer helping clients set up IRS payment plans, the key decisions are: which agreement type fits the balance and the client's capacity, which application method to use, and where your authority as the preparer begins and ends. This guide covers all of it, from credential distinctions through the Online Payment Agreement workflow, Form 9465, setup fees, penalty math, default and reinstatement, partial-pay strategy, and a post-agreement checklist.
This guide is written for tax preparers assisting clients with IRS collection matters. IRS procedures, fee schedules, and eligibility thresholds are subject to change. Verify current requirements at IRS.gov before advising any client on a specific course of action. This guide is informational and does not constitute legal or professional advice.
Who Can Help Clients with Installment Agreements: The Credential Distinction
Before you take action on a client's behalf, confirm what you are authorized to do. This is a different analysis than audit representation, and the practical scope for non-credentialed preparers is wider here than it is in Collections generally. The installment agreement program is authorized by IRC 6159: Installment Agreement Statute, which also creates the guaranteed IA right for liabilities under $10,000 and governs the CSED tolling effect of every agreement.
Non-credentialed preparers (PTIN only): streamlined IAs via OPA with Form 2848
A preparer who holds only a PTIN and no credential (EA, CPA, or attorney) can apply for a streamlined installment agreement on behalf of a client using the IRS Online Payment Agreement (OPA) tool at IRS.gov, provided the client has a valid Form 2848 Power of Attorney on file with the IRS Centralized Authorization File (CAF) unit granting that authority. Verify current access requirements at IRS.gov, as the IRS may update the authorization requirements for OPA access by representatives.
This is an important distinction from an Offer in Compromise (OIC). An OIC is a Collections matter requiring full representation rights, which means only credentialed practitioners can file it on a client's behalf. A streamlined installment agreement through OPA is a different process. The OPA tool is designed to allow authorized representatives to apply without full representation rights in Collections, subject to the Form 2848 authorization on file. See the Form 2848 and Form 8821 guide for mechanics on establishing the authorization correctly, and see the OIC preparer guide for the credential requirements on that path.
Credentialed preparers (EA, CPA, attorney): full representation rights in Collections
Enrolled agents, certified public accountants, and attorneys hold unlimited representation rights before all IRS divisions, including Collections. They can represent clients in all installment agreement types, including non-streamlined agreements requiring financial statements, and in related Collections matters such as levy releases and lien subordination. For the credential path to full representation rights, see the EA exam guide and the representation rights guide.
Scope limits and engagement letter language
Regardless of credential level, document the scope of your engagement in writing before you take action on a client's collection matter. If you are a PTIN-only preparer assisting with a streamlined IA, your engagement letter should state that your scope is limited to the installment agreement application and does not include representation before Collections, Appeals, or other IRS divisions. See the preparer liability guide for how scope language protects both you and the client.
Types of IRS Installment Agreements
Four installment agreement structures exist, each with different eligibility thresholds, documentation requirements, and monthly payment calculations. Match the agreement type to the client's balance before you start the application.
Guaranteed installment agreement: under $10,000, paid within 3 years
When the total balance owed (including tax, penalties, and interest) is under $10,000 and the client can pay it in full within 3 years, the IRS is legally required to grant the agreement. No financial statement is required. The client must have filed all required returns and must not have had an installment agreement default in the prior 5 years. This is the cleanest path for clients with small balances. The IRS cannot reject the application if these conditions are met, which means the outcome is predictable and the preparer's role in the application process is straightforward.
Streamlined installment agreement: $10,001 to $50,000, up to 72 months
The streamlined installment agreement threshold has been $50,000 for most applicants. In some cases the IRS exercises discretion to extend streamlined treatment to higher balances; verify current eligibility at IRS.gov, as thresholds and discretionary practices may change. No financial statement is required for the streamlined IA, and repayment can extend up to 72 months. This is the most common agreement type that preparers help clients establish, because it covers the majority of individual balance-due situations and avoids the financial disclosure required by the non-streamlined path. The monthly payment must be enough to satisfy the balance (plus ongoing accruals) within 72 months. Use the IRS OPA tool to calculate a compliant minimum monthly amount.
Non-streamlined installment agreement: over $50,000 or longer than 72 months
When the balance exceeds the streamlined threshold or when the client cannot pay within 72 months, a non-streamlined agreement requires a Collection Information Statement. The IRS uses Form 433-A (Collection Information Statement for Wage Earners and Self-Employed Individuals) or Form 433-F (a shorter version used in many automated collection situations) to evaluate the client's ability to pay; our Form 433-A and 433-B Collection Information Statement Guide walks through documenting ability to pay line by line. The IRS may also file a Notice of Federal Tax Lien for agreements in this category. Full representation rights are strongly recommended for non-streamlined agreements; a credentialed practitioner can negotiate terms, respond to IRS financial analysis, and address lien issues. If your client's balance exceeds the streamlined threshold, see the referral section at the end of this guide.
Partial-pay installment agreement: paying what the client can afford
A partial-pay installment agreement (PPIA) allows the client to make payments based on their demonstrated ability to pay, even if those payments will not satisfy the entire balance before the Collection Statute Expiration Date (CSED). At the CSED, the IRS loses its legal right to collect the remaining balance. PPIAs require a full financial disclosure (Form 433-A or 433-F), IRS analysis of ability to pay, and are subject to periodic review by the IRS. The strategic use of a PPIA is covered in Section 8 of this guide. Full representation rights are recommended for PPIA cases.
Online Payment Agreement (OPA) Workflow
The IRS Online Payment Agreement tool at IRS.gov is the fastest way to establish a guaranteed or streamlined installment agreement. Approved applications generate a confirmed agreement immediately, without the processing delay of a paper Form 9465. Verify current OPA access procedures and e-services requirements at IRS.gov before beginning; the IRS updates its online tools and access protocols periodically.
Form 2848 requirement for representative access
To access OPA on behalf of a client, the client's Form 2848 must be on file with the IRS CAF unit, and it must cover the specific tax year(s) and tax type at issue. The OPA access path for representatives is through IRS e-services at IRS.gov. Without a current, CAF-recorded Form 2848, the representative cannot access the client's account through OPA and cannot submit the application on the client's behalf. Verify current Form 2848 requirements and OPA authorization procedures at IRS.gov before advising clients, as the IRS may update access requirements.
Confirm the Form 2848 is on file and covers the right scope
Before opening OPA, verify that the client's Form 2848 has been processed by the CAF unit (not just submitted) and that it covers the specific tax years and tax type for which the balance is owed. You can check authorization status through IRS e-services. If the Form 2848 is not yet processed, allow time for CAF processing before attempting OPA access, or apply using Form 9465 by paper in the interim.
Access OPA through IRS e-services and confirm the client's balance
Log in to IRS e-services at IRS.gov and navigate to the Online Payment Agreement tool. Confirm the total balance due for the applicable tax years, including all accrued penalties and interest. Use this figure -- not the original return balance -- to calculate the required monthly payment and to confirm which agreement type applies. If the balance originated from a CP2000 underreporter notice, confirm the client has already responded to the notice and the balance has been formally assessed before setting up a payment plan. See the CP2000 notice preparer guide for the correct response workflow.
Select the agreement type and payment method
Choose between a direct debit agreement (lower setup fee, lower default risk) and a non-direct debit agreement. Direct debit draws the monthly payment automatically from the client's bank account. The setup fee difference between direct debit and other payment methods is meaningful; see Section 5 of this guide for current fee amounts (verify all fees at IRS.gov before advising). If the client is low-income as defined by IRS guidelines, confirm whether they qualify for a reduced or waived setup fee.
Submit and confirm the effective date
Complete the OPA application and submit. The IRS will display a confirmation screen and provide an agreement number. The agreement becomes effective on the approval date shown in the confirmation, not on the date of the first payment. Save the confirmation for the client file. The first payment due date will be stated in the confirmation and should be communicated to the client immediately.
Form 9465: The Paper Alternative
Form 9465 (Installment Agreement Request) is the paper form for requesting a payment plan when OPA is unavailable, when the client has a balance type that OPA does not accommodate, or when the preparer does not have OPA access. OPA is faster for eligible applicants; the IRS processes paper Form 9465 submissions on a longer timeline. Verify current processing times at IRS.gov, as they vary by IRS workload and may change significantly.
When to use Form 9465 instead of OPA
Use Form 9465 when: the client's balance type or situation is not supported by OPA; the Form 2848 is submitted but not yet processed by the CAF unit; the client wants to file by mail rather than online; or you are filing a non-streamlined agreement that requires submission with Form 433-A or 433-F. Form 9465 can be submitted as a standalone form or attached to the tax return for the year with the balance due.
Completing Form 9465
The form requests basic identifying information, the tax year(s) at issue, the total amount owed, the proposed monthly payment amount, and the requested payment start date. For direct debit, the client completes the banking information section. The proposed monthly payment should be at least enough to satisfy the balance plus projected accruals within 72 months for a streamlined IA; the IRS may counter-propose a higher monthly payment if the submitted amount is below what is needed to pay off within the allowable period. Instructions for Form 9465 are published at IRS.gov. Always refer to the current instructions before completing the form, as the IRS may update fields or requirements.
Processing time and interim collection risk
A pending Form 9465 does not suspend IRS collection action the same way a confirmed agreement does. The IRS generally refrains from enforced collection while a first-time installment agreement request is pending and in processable form, but this is not a guarantee. For clients with levies or lien issues, do not rely on a pending paper application to stop collection activity; contact the IRS directly or engage a credentialed practitioner to intervene. Verify current IRS collection procedures for pending IA requests at IRS.gov.
Installment Agreement Setup Fees
The IRS charges a user fee to establish an installment agreement. The fee amount depends on the payment method and how the application is submitted. All fee amounts listed below are subject to change. Verify current fees at IRS.gov before advising clients, as fees may change with IRS guidance updates.
- Direct debit installment agreement: $22 (verify current fee at IRS.gov; fees are subject to change). Low-income applicants who qualify under IRS income guidelines pay $0 for a direct debit agreement. The direct debit option carries the lowest setup fee and reduces the risk of inadvertent default from a missed manual payment.
- Payroll deduction installment agreement: $107 (verify current fee at IRS.gov; fees are subject to change). This option draws payments directly from the client's paycheck through their employer and requires coordination with the employer.
- Other installment agreement (applied for online): $69 (verify current fee at IRS.gov; fees are subject to change). This covers agreements applied for through OPA where the payment is not direct debit from a bank account.
- Other installment agreement (applied for by phone, mail, or in-person): $225 (verify current fee at IRS.gov; fees are subject to change). The highest setup fee applies to paper, phone, and in-person applications for non-direct-debit agreements, which is another reason to use OPA when it is available.
For most clients who qualify for a streamlined IA, a direct debit agreement applied for through OPA minimizes the upfront cost and the default risk. Present the fee comparison to clients before they decide on a payment method so the choice is informed.
Penalty and Interest: What Continues to Accrue
Many clients assume that an installment agreement stops the clock on penalties and interest. It does not. Penalties and interest continue to accrue on the unpaid balance throughout the agreement period. An installment agreement stops enforced collection; it does not stop the meter.
The failure-to-pay penalty reduction under IRC Section 6651(h)
There is one meaningful penalty benefit once an installment agreement is approved. Under IRC Section 6651(h), the failure-to-pay penalty is reduced from 0.5% per month to 0.25% per month while an approved installment agreement is in effect. Verify current penalty rates at IRS.gov, as penalty rates are subject to change. This reduction cuts the ongoing penalty accrual in half compared to a taxpayer who owes but has made no arrangement. It is a real benefit, but it does not eliminate the ongoing cost.
Net cost analysis for the client
For a client deciding between an installment agreement and a more aggressive resolution strategy (such as an OIC), the total cost comparison matters. Run the numbers before the client commits to a long-term IA. A client with a $30,000 balance paying over 72 months will pay materially more than $30,000 due to ongoing interest and the reduced (but not eliminated) penalty accrual. Confirm the current IRS underpayment interest rate (tied to the federal short-term rate plus 3%) at IRS.gov when doing this analysis. If the client can pay more quickly, a shorter agreement reduces total cost. If the client genuinely cannot pay the full balance, the partial-pay IA or OIC may produce a better outcome and warrant the additional work involved. For a structured comparison of when CNC, a PPIA, or an OIC displaces a standard IA, work through our IRS collection alternatives decision guide.
Present the accrual reality plainly in your client communication. Clients who are surprised by a balance that grew during their payment plan generate complaint calls and, in some cases, IRS default situations when they stop paying because the number "doesn't look right." A clear explanation upfront prevents that outcome.
If the client has incurred significant failure-to-file or failure-to-pay penalties, a first-time abatement request can be filed alongside or after establishing the installment agreement. See the IRS penalty abatement guide for tax preparers.
The interaction between a payment plan and the collection statute also affects the total-cost analysis: a pending IA proposal tolls the clock while it is under consideration. See the IRS collection statute expiration date (CSED): how installment agreements affect the 10-year clock guide before advising a client to enter an agreement late in the collection period. Separately, a balance large enough to meet the statutory threshold can trigger State Department action even while the client is paying; the IRS passport certification and seriously delinquent tax debt (IRC 7345) guide covers when an IA reverses certification.
Default and Reinstatement
An installment agreement can be terminated by the IRS if the taxpayer fails to meet its terms. Understanding what triggers a default, and how to reinstate, is part of the preparer's responsibility when managing a client through an active IA.
What triggers a default
Common default triggers include: missing a scheduled payment; incurring a new federal tax liability (if the client fails to pay their current-year taxes on time while the IA is in effect, the new balance can cause the IRS to terminate the agreement); failing to file a required return; providing materially inaccurate financial information in the application; and failure to update the IRS on a material change in financial condition for a non-streamlined or partial-pay IA. Direct debit agreements default less frequently than manual payment plans because the payment is automatic, but a closed or unfunded bank account still triggers default. When a client ignores balance-due notices in the first place, or when a defaulted agreement causes the IRS to resume enforced collection, the account moves back through the escalating series of balance-due and levy notices; the IRS collection notice sequence guide maps that notice stream so you can identify where the client stands before the next enforcement step.
Reinstatement: how to fix a defaulted agreement
After a default, the client can request reinstatement of the installment agreement. Acting quickly after a missed payment improves the likelihood of reinstatement before the IRS escalates to enforced collection. The IRS charges a user fee for reinstatement of a defaulted agreement; verify the current reinstatement fee at IRS.gov before advising clients, as fees are subject to change. Contact the IRS at the number on the default notice or through e-services to initiate reinstatement. For clients who default frequently, the preparer should review whether the original monthly payment was realistically sustainable and whether a lower payment (with a longer term, within allowable limits) would be more appropriate.
Partial-Pay IA Strategy: The CSED and What It Means
For clients who cannot afford to pay the full balance owed over any realistic installment period, the partial-pay installment agreement (PPIA) is a legitimate resolution tool. It is not a default position, and it requires financial disclosure, but it can result in a portion of the liability being extinguished at the end of the collection period.
The Collection Statute Expiration Date
The IRS has 10 years from the date of assessment to collect a tax liability. This is the Collection Statute Expiration Date (CSED). After the CSED passes, the IRS is legally prohibited from collecting the remaining balance. For a PPIA, the client makes monthly payments based on their demonstrated ability to pay (calculated from the financial analysis on Form 433-A or 433-F), and any remaining balance that has not been paid by the CSED is extinguished by operation of law, not by IRS concession.
Several actions toll (pause) the CSED and extend the IRS collection window: filing for bankruptcy, submitting an OIC, requesting a Collection Due Process hearing, executing a waiver, and certain other actions. When calculating a PPIA strategy, always verify the CSED for each tax year at issue by pulling the client's IRS transcript and accounting for any tolling events. A credentialed practitioner familiar with CSED analysis should handle PPIA cases.
Calculating minimum acceptable payments
The PPIA monthly payment is set at the client's ability to pay, calculated as monthly income less allowable expenses using IRS Collection Financial Standards. The IRS reviews the financial analysis and may counter-propose a higher payment if it disagrees with the expense allowances. For practitioners new to Collection Financial Standards analysis, the IRS publishes the applicable expense tables at IRS.gov. The PPIA is subject to periodic review (typically every 2 years); if the client's financial situation improves, the IRS may increase the required monthly payment.
When to Refer to an EA or Tax Resolution Specialist
Not every installment agreement situation is appropriate for a PTIN-only preparer to handle. Knowing when to refer is as important as knowing the mechanics of the application.
- Balance exceeds $50,000. When the client's total balance exceeds the streamlined threshold, a non-streamlined agreement requiring full financial disclosure and IRS negotiation is likely required. A credentialed practitioner (EA, CPA, or attorney) should handle the Collection Information Statement analysis, negotiate the monthly payment, and address any potential lien filing. Refer promptly rather than attempting to navigate non-streamlined territory without full representation rights.
- Trust fund recovery penalty (TFRP). If the client's balance includes, or may include, a trust fund recovery penalty assessment under IRC Section 6672, this is a Collections matter that goes beyond routine installment agreement work. TFRP cases involve personal liability assessments for employment tax trust fund amounts and frequently require representation before the IRS Collection function. Once a TFRP balance is formally assessed against the responsible person, it can be resolved through an installment agreement like other assessed liabilities; see the trust fund recovery penalty guide for tax practitioners for the responsible person analysis and appeal workflow. Refer to a credentialed practitioner.
- Criminal referral risk. If there is any indication that the IRS is treating the client's balance as potentially involving willful tax evasion or other conduct that could lead to a criminal referral, stop and refer to a tax attorney immediately. Attorney-client privilege applies to communications with a tax attorney in ways it does not apply to communications with a CPA or EA. Do not continue to assist in this situation without an attorney in place.
- Active levies or liens. If the IRS has already issued a levy or filed a Notice of Federal Tax Lien, the client needs immediate representation from a credentialed practitioner to request a levy release or lien subordination alongside the installment agreement. These are Collections actions requiring full representation rights. Under IRC 6343: Levy Release and Return of Property, an approved installment agreement triggers mandatory IRS levy release unless the agreement expressly allows the levy to continue.
When you refer, document the referral in writing and confirm that the client received it. Do not leave a client in limbo between your disengagement and the new representative's engagement. See the preparer liability guide for engagement letter and referral documentation practices.
When a client genuinely cannot pay the full balance even over time, an installment agreement may not be the right tool; see the IRS Offer in Compromise guide for the alternative and when full representation rights are required. For the statutory framework for the offer in compromise -- the primary collection alternative for taxpayers who cannot satisfy a full liability through an installment agreement -- see the IRC 7122: OIC Statutory Framework guide.
If a levy notice or a Notice of Federal Tax Lien filing has already triggered the client's appeal rights, the IRS Collection Due Process (CDP) hearing guide covers the 30-day window, Form 12153, and the collection alternatives that can be proposed at the hearing.
Post-IA Checklist for the Preparer
Once the installment agreement is confirmed, the preparer's work is not finished. Run through these steps before closing the engagement.
- Confirm direct debit authorization and first payment date. If the client chose a direct debit agreement, verify that the bank account information entered in the OPA application or on Form 9465 is accurate. Confirm the first payment date with the client and ask them to verify their account is funded before that date. An NSF on the first payment can cause an immediate default.
- Update the client file with the agreement confirmation. Save the OPA confirmation screen or a copy of the submitted Form 9465 and any IRS acknowledgment letter to the client file. Note the agreement number, the monthly payment amount, the payment due date each month, and the expected payoff date if the client makes minimum payments.
- Review withholding and estimated payments to prevent a new balance. A client who makes installment payments on the current year's balance while also underpaying current-year taxes is on a path to a new balance that could trigger IA default. Review the client's W-4 withholding or estimated payment schedule and recommend adjustments. Preventing the next balance is as important as resolving the current one.
- Remind the client of compliance requirements during the IA. An active installment agreement requires the client to file all required returns on time and pay all current-year taxes on time. Missing a current-year filing or payment obligation can trigger default on the IA. Make this clear in writing, not just verbally.
- Document scope limits in the engagement letter. If your engagement was limited to the IA application and does not cover ongoing monitoring, levy response, or representation in any future collection matter, state that explicitly. A client who returns a year later with an IA default situation should have a written record of what you were and were not retained to do.
Penalty abatement can reduce the balance subject to an installment agreement before the agreement is established. The IRS penalty abatement practitioner guide covers AEP, first-time abatement, Form 843, and the PPS workflow for removing failure-to-file and failure-to-pay charges.
When a client on an installment agreement faces a Notice of Federal Tax Lien blocking a property transaction or new financing, the tax lien discharge, subordination, and withdrawal guide covers Form 14135 discharge, Form 14134 subordination, and Form 12277 withdrawal under IRC 6325 and 6323(j).
Frequently Asked Questions
Can a non-credentialed preparer set up an IRS installment agreement for a client?
Yes, with limitations. A PTIN-only preparer can apply for a streamlined installment agreement through the IRS OPA tool on a client's behalf if the client's Form 2848 is on file with the IRS CAF unit covering the applicable tax years. This is different from an OIC, which requires full representation rights. Credentialed practitioners (EA, CPA, attorney) have full representation rights in Collections. Verify current OPA access requirements at IRS.gov before proceeding.
What is the difference between a guaranteed and a streamlined installment agreement?
A guaranteed IA applies to balances under $10,000 payable within 3 years; the IRS must grant it if eligibility conditions are met, and no financial statement is required. A streamlined IA covers balances up to $50,000 for most applicants (verify current thresholds at IRS.gov) with up to 72 months to pay; it also requires no financial statement and is the most common type preparers help clients obtain.
Do penalties and interest stop when a client is on an installment agreement?
No. Penalties and interest continue to accrue on the unpaid balance throughout the IA period. However, the failure-to-pay penalty is reduced from 0.5% per month to 0.25% per month while an approved IA is in effect, under IRC Section 6651(h). Verify current penalty rates at IRS.gov. The total amount paid over a long installment agreement will exceed the original tax balance.
What happens if a client misses a payment?
A missed payment can trigger default and IRS termination of the installment agreement. The client can request reinstatement; acting quickly after a missed payment improves the outcome. The IRS charges a user fee for reinstatement; verify the current fee at IRS.gov before advising clients, as fees are subject to change. Direct debit agreements are less likely to default because payment is automatic.
Is Form 9465 or the Online Payment Agreement faster?
The Online Payment Agreement tool at IRS.gov produces a confirmed agreement immediately for eligible applicants. Form 9465 submitted by paper takes significantly longer to process; verify current processing times at IRS.gov, as they vary by IRS workload. OPA also carries a lower setup fee for non-direct-debit agreements ($69 online versus $225 by phone, mail, or in-person; verify current fees at IRS.gov). Use OPA whenever the client and situation are eligible.
