Once a periodic-payment OIC is moving, the part that keeps it alive is the monthly payment, and Form 656-PPV is what you attach to each one. Miss a payment and the IRS can return the whole offer, no matter how strong the underlying case is. The voucher is plain, but it is the thread that holds the offer together while the review runs.

This is the Rev. 4-2020 voucher, used for every installment on a 6 to 24 month payoff. Make the check payable to United States Treasury, round the amount up to the next whole dollar, and mail it to the Memphis or Brookhaven COIC Unit named in your IRS letter, or pay through EFTPS using the Offer in Compromise subsequent periodic payment option. The OIC application fee is $205, and Low-Income Certification can exempt you from the fee and from monthly payments during review, though it never waives the offered tax itself.

Key Takeaways

• Form 656‑PPV is the voucher you use for each required periodic installment on a pending OIC. You keep paying monthly until the IRS issues a formal decision letter classifying the offer as accepted, rejected, returned, or withdrawn – an online status change, phone update, or acknowledgement letter does not end the payment obligation. Payments are generally nonrefundable.
• You can mail a check or money order with the voucher, or you can pay electronically. For electronic payments, enroll in EFTPS and select the "Offer in Compromise - Subsequent Periodic Payment" option, and include your OIC number so the IRS credits the right case. IRS Direct Pay is not accepted for OIC periodic payments.
• The OIC application fee is $205 as of 2025. Low‑income certification can exempt you from the fee and from making monthly payments during review – but it does not waive the offered tax liability itself, and any voluntary payments you choose to make during review are still applied to your tax debt.
• Periodic payment offers are paid in 6 to 24 months. You must send the first payment with Form 656, then continue monthly with 656‑PPV while the IRS evaluates your offer. Missing a payment can cause a return.
• Addresses can change. Follow the payment address in your IRS letter. As of April 28, 2025, payments were directed to Holtsville, NY or Memphis, TN based on where you filed.

What Form 656‑PPV Is and When You Use It

Form 656‑PPV is a simple payment voucher that ties your check or money order to your pending OIC. It carries your name, SSN or EIN, your OIC number, and the amount due for that month. The goal is accuracy and speed, nothing more, nothing less. If you mail payments, you attach the voucher so the IRS cashiers and the OIC system can post the funds to your case without delays. If you pay online, you do not mail the paper voucher, but you still identify the payment as an OIC subsequent periodic payment and include the OIC case number or designation fields so the IRS matches your payment.

Why it matters. During review, your offer is pending. The IRS expects the exact monthly amount, on time, every time, for up to 24 months depending on your terms. Those payments are generally nonrefundable and are applied to your tax debt. If you skip, the IRS typically gives you one chance to catch up. If you do not, the offer is returned without appeal rights.

Mailed vs electronic payments

You have two clean paths.

• Mailed payments, Use the printed 656‑PPV voucher that arrives in your IRS letter. Enclose it loosely with each check made payable to “United States Treasury” – do not staple, paperclip, or tape the check to the voucher, since stapled items damage IRS scanning equipment. Do not make the check out to “IRS” or “Internal Revenue Service” – those are not the correct payee and can cause the payment to be rejected or delayed. Mail to the address shown in your letter, which, as of April 28, 2025, was Holtsville, NY or Memphis, TN based on where you originally filed. Keep copies. Use trackable mail.
• Electronic payments, Enroll in EFTPS and select “Offer in Compromise - Subsequent Periodic Payment.” IRS Direct Pay is not accepted for OIC periodic payments. Enter your OIC number and designation so the credit lands in the right place. Selecting any other EFTPS category (for example, a generic “1040 balance due”) routes the funds wrong and can delay OIC processing.

What happens if you miss or miscode a payment

• Missed payment, The IRS usually issues a contact letter and gives you one chance to fix it. If you do not pay, the offer is returned (a return is IRS-initiated for non-compliance and is distinct from a taxpayer-initiated withdrawal). Payments already made are applied to your balance. The application fee is kept.
• Miscoded payment, If you send money to the IRS without the OIC designation or OIC number, your payment can post to the wrong period. You can ask the IRS to transfer the payment, but it can delay your case and risk a return if it looks like a missed installment. The IRS encourages you to designate OIC payments to the correct liability.

Who Should Use Form 656‑PPV

If you filed Form 656 using the periodic‑payment option, you will use 656‑PPV for each monthly installment during review. This applies to individuals and to businesses that submit OICs. Businesses file Form 433‑B(OIC), individuals file Form 433‑A(OIC), and both continue monthly payments if they choose periodic terms. IRS internal guidance specifically references handling periodic payments that arrive with Form 656‑PPV, including offers submitted by corporations.

Important clarifications for 2026.

• Bankruptcy, If you are in an open bankruptcy, you are not eligible to submit an OIC, so you would not be making 656‑PPV payments.
• Territories and foreign addresses, You can still pursue an OIC if you meet the rules. The older limitation many people remember is with the online pre‑qualifier tool, not with the OIC itself. When in doubt, use the 656‑B booklet or your Online Account.
• Low‑income certification, If you qualify, you do not send the application fee, and you do not send monthly payments during review. That is a real relief for tight budgets.

Required Forms and Documentation, Your OIC Packet Checklist

If you are just starting or you need a quick audit of your packet, use this list. It reflects how the IRS instructs you to build a complete OIC.

• Form 656 for each taxpayer and each entity. If you have both personal and business liabilities, you file separate Forms 656. Include the $205 application fee for each, unless low‑income certified. Include the first payment for each periodic‑payment offer.
• Financials, Form 433‑A(OIC) for individuals and sole proprietors. Form 433‑B(OIC) for businesses. Attach bank statements, pay stubs, P&Ls, and proof for every number that matters.
• Initial payment, Send it with the offer. Then, beginning the very next month, send monthly payments using 656‑PPV or pay online using the OIC selections until the IRS makes a decision.
• Low‑income certification, If you qualify under the guidelines in Section 1 of Form 656, you do not send the fee or monthly payments during review.

Tip from the trenches, I keep a simple two‑column log, “date due” and “date paid,” and I set calendar reminders five days early. It prevents avoidable returns.

Income and filing status, what the IRS expects to see

Your income and household size drive your allowed expenses and your monthly disposable income calculation. Match your filing status to your most recent return. List every income source, including wages, self‑employment draws, Social Security, rental income, and investment income. If you claim dependents, include ages so the IRS can test your household allowances. Attach evidence, for example two months of pay stubs, bank statements, and if you are self‑employed, a current P&L and proof of federal tax deposits.

• State filing status accurately. It shapes your standard allowances.
• Report monthly gross income from all sources.
• Document with pay stubs, P&L, and bank statements.

Monthly allowable expenses, how to avoid pushback

Use the IRS national and local standards where required, then document any necessary amounts that exceed those standards. Food, clothing, and miscellaneous categories follow national standards. Housing and utilities have county caps. Transportation is split between ownership costs and operating costs, each with different limits. For childcare, medical, and school costs, gather proof. Precision here helps you avoid delays and rework during the OIC investigation.

• Keep receipts for childcare, unreimbursed medical, and special circumstances.
• Separate vehicle loan or lease from fuel, insurance, and maintenance.
• If you exceed a cap for a necessary reason, include a short note and proof.

Asset values and equity, the other half of the math

List every account and asset with current value and any secured debt. Use fair market values for vehicles and property, then subtract loans to show equity. Retirement accounts require the current balance and any restrictions or penalties. The IRS will add available equity to your monthly disposable income calculation to arrive at a reasonable collection potential. Keep documentation ready, such as bank and brokerage statements, loan statements, and any appraisal you rely on.

• Bank, brokerage, and cash equivalents.
• Vehicles with payoff statements and a value source.
• Real property with mortgage statements and an appraisal or valuation.
• Retirement balances with plan rules on loans or withdrawals.

How the IRS Calculates a Preliminary Offer Amount

At a high level, the calculation blends two pieces, your monthly disposable income and your asset equity. For periodic‑payment offers, the IRS applies a multiplier consistent with 6 to 24 months of payments. The common planning target many practitioners use is 24 months for periodic offers, as noted in the Internal Revenue Manual.

Step 1, estimate monthly disposable income

Start with gross monthly income. Subtract allowable expenses using the national and local standards and documented necessary costs. The result is your disposable income for OIC purposes. If you are self‑employed, be realistic about seasonality and show current federal tax deposits where required.

Step 2, add available asset equity

Add the net equity in your bank accounts, investments, vehicles, and real property. The IRS may consider penalties or restrictions on retirement accounts when assessing equity. The sum of disposable income over the offer’s payment window plus equity becomes your preliminary offer amount. This is an estimate until the IRS reviews your documentation.

Exception Process for Special Hardships

Sometimes the math says one thing, but life says another. If serious illness, disability, or other compelling circumstances make the standard periodic amount unrealistic, you can ask the IRS to consider an exception under effective tax administration rules. You still submit Form 656 with your financial statements. You include supporting records that prove the hardship, for example medical bills, treatment summaries, and proof of reduced income. If the IRS agrees, it can accept a lower amount or adjust the payment expectations.

Keep it simple, tell a clear story, show proof, and tie every document to a specific point you want the IRS to accept.

What to include in a hardship request

• A short cover note that explains the situation in plain language.
• Medical records or letters from providers, plus recent bills or insurance statements.
• Proof of income disruption, for example employer letters, unemployment records, or business revenue drops.
• A revised budget that still follows IRS standards, with receipts for any necessary items above the caps.
• Any asset restrictions, for example retirement plan penalties, loan limits, or property that is not marketable.

Practical tips I use with clients

• Put the must‑read facts in the first page. The IRS reviewer should not hunt for them.
• Label each exhibit, and reference those labels in your cover note.
• Do not send originals, send clean copies, and keep a full backup set.

Submitting Your Offer and Paying with Form 656‑PPV

You submit the OIC packet first, then you start paying. The initial payment and the application fee go in with Form 656. After that, each monthly installment gets its own payment, and that is where Form 656‑PPV comes in.

How to fill out Form 656‑PPV, line by line

• Name and taxpayer ID, use the same name and SSN or EIN that you used on Form 656.
• OIC case number, if the IRS has already assigned one, include it. If not, use your name, SSN or EIN, and the periods listed on your offer.
• Payment amount, enter the exact periodic amount you agreed to in your OIC, rounded up to the nearest whole dollar (standard tax-return rounding is not allowed on this voucher).
• Tax periods, list the periods included in your offer as shown on Form 656.
• Signature and date, sign if the voucher includes a signature line, then date it and make a copy for your records.

Mailing or paying online

• If mailing, write checks or money orders to “United States Treasury.” Enclose the voucher loosely with each payment; do not staple, paperclip, or tape it to the check. Use trackable mail, and keep the receipt.
• If paying online, follow the OIC payment path in your IRS Online Account or the approved payment systems. Use the OIC designation fields and include your OIC number. Keep the confirmation page.

A quick comparison

Common Mistakes that Get Offers Returned

These three checklists are SOP-ready. Paste them into your practice manual or hand them to a client running their own packet. Each item maps to a Form 656-PPV requirement that, if skipped, can move the offer from 'investigating' to 'returned' without appeal rights.

Timeline and Tracking

A periodic‑payment offer takes time. While the IRS reviews your financials, you keep sending the monthly amount. Processing speeds vary by workload and by how complete your packet is. Two habits help a lot, a simple payment log and a document index.

My two simple tools

• Payment log, make two columns, “due date” and “date paid,” plus a third column for “confirmation or check number.”
• Document index, list each form and exhibit, with the date you sent it, and the page count. When the IRS asks for a copy, you can send it in minutes.

Who can use Form 656‑PPV, a quick recap

• You filed Form 656 using the periodic payment option, and you are filing compliant.
• You are not in open bankruptcy.
• You are an individual filer (using your SSN) or a business filer (using your EIN) – Form 656-PPV is used by both, since either Form 433-A(OIC) or Form 433-B(OIC) financials can accompany a periodic-payment Form 656.
• Your offer is based on doubt as to collectibility or on effective tax administration.
• You have sent the initial payment and application fee, unless low‑income certification applies.

If any of these are not true for you, revisit the OIC booklet and consider another path. The goal is to avoid a return, save time, and use the rule set that fits your situation.

Alternatives if You Do Not Qualify or If the Math Does Not Work

An Offer in Compromise is not the only way forward. If you do not qualify, or if the monthly number would stress your budget, consider one of these paths.

• Installment agreement, spread the balance over time, often up to 72 months, and keep the account compliant.
• Short‑term payment plan, pay in full within a few months, and skip the installment setup fee.
• Currently Not Collectible, if any monthly payment creates hardship, you can request CNC. Collections pause while interest and penalties continue.
• Doubt as to liability, if the core issue is that the tax is wrong, use the liability offer on Form 656‑L or pursue an appeal.
• Penalty relief, if you qualify for first‑time abatement or reasonable cause, reduce the add‑ons, then reassess your plan.

Simple Checklist, Do This Every Month Until You Get a Decision

• Put the due date on your calendar with a five‑day early reminder.
• Decide, mail with voucher or pay online with OIC designation.
• Pay the exact amount shown on your offer.
• Keep proof, either a postal receipt and a copy of the check or a payment confirmation number.
• Update your payment log and your document index.
• Open all IRS letters the day they arrive and respond on time.

For CPA and EA Firms That Support OIC Clients

If you run a tax practice, missed or misapplied OIC payments can ruin a client’s best chance at relief. Build a standard playbook that includes a payment calendar, preprinted vouchers, a quick‑send cover sheet, and a review checklist. If your team is buried in seasonal work, standardize how vouchers are prepared, how confirmations are stored, and who checks the log weekly. That kind of workflow discipline prevents returns and protects client trust.

Accountably helps firms create controlled offshore delivery that keeps this work moving on time, at quality, and at scale. Our teams work inside your systems and templates, and we build the review guardrails that reduce rework. If you support OIC clients and want fewer bottlenecks, we can help you standardize the process without losing oversight.

Final Thoughts and Next Steps

Form 656‑PPV is small, but it carries big weight. Treat every monthly payment like a deadline that protects your pending offer. Send the first payment with your OIC, then keep paying each month until you get a decision. Use the voucher with mailed checks, or use the same data points when you pay online. Keep a log, save every confirmation, and respond quickly to any IRS letter. If special hardships apply, gather proof and ask for an exception. If the offer path is not a fit, choose an alternative that keeps you compliant and protects your budget.

Reusable Checklists

OIC casework is a long calendar. A periodic-payment offer runs 6 to 24 months on the books (per Form 656-PPV instructions, Rev. 4-2020), and every one of those months needs an accurate voucher, a correctly coded payment, and a clean record in the client file. Per Publication 594, the IRS Collection process routes Form 656-PPV submissions through two dedicated COIC Units, and a single miscoded payment or wrong address can move an offer from 'investigating' to 'returned' without an appeal.

The fix is not more effort. It is a delivery rhythm that takes voucher prep, payment QA, and the IRS contact log out of email threads and into a documented monthly cycle the team can rely on.

• Lock the OIC number, SSN or EIN, and tax-period designation into a single client record at intake so every monthly voucher pulls the same identifiers.
• Code EFTPS payments only as 'Offer in Compromise - Subsequent Periodic Payment'; flag and reject any generic '1040 balance due' coding before it leaves the workflow.
• Route mailed vouchers by state of residence to the correct COIC Unit (Memphis for the 15 listed states; Brookhaven for the remaining 36 states, DC, PR, and foreign-address filers per Form 656-PPV mailing instructions).
• Track each installment in a two-column 'due / paid / confirmation #' log and reconcile against the IRS acknowledgment before the next month closes.
• Treat low-income-certified files as a separate workflow lane. The periodic-payment requirement is waived under Section 1 of Form 656, but any voluntary payment still needs to be logged and applied to the underlying tax debt.

This is the operational core of how Accountably's tax delivery teams handle Offer in Compromise casework: the monthly voucher, the EFTPS coding, and the COIC routing all sit inside a documented SOP with reviewer signoff, so the offer never gets returned for a calendar miss.

Keep 656-PPV Season From Stalling

OIC delivery has a calendar problem most teams underestimate. Treasury Regulation §301.7122-1 makes continued monthly installment payment a condition of an open periodic-payment offer, so each active client carries a recurring monthly task that runs until one of four IRS decision-letter outcomes lands (accepted, rejected, returned, or withdrawn, per the Form 656-PPV instructions, Rev. 4-2020). Across a portfolio of OIC files, a single skipped month, a check made out to 'IRS' instead of 'United States Treasury', or a payment rounded down instead of up to the next whole dollar can pull an offer back into non-processable status before the reviewer sees it.

The fix is procedural, not heroic. Treat the OIC payment cycle as a recurring delivery workflow, not a periodic exception, and a growing OIC bench becomes manageable inside the same monthly close discipline used for any client engagement.

• Confirm Form 656 Section 1 status on intake. If Low-Income Certification applies, the $205 application fee and the periodic payment requirement are both waived; routing those files through the standard voucher workflow burns hours and creates confusion on the IRS side.
• Standardize the check payee as 'United States Treasury' (not 'IRS' or 'Internal Revenue Service') across the entire OIC client base, and write the SSN or EIN on the face of every check so payments can still be matched if the voucher and check separate during processing.
• Round every monthly installment up to the next whole dollar before the voucher is signed. Standard tax-return rounding is not permitted on Form 656-PPV, so a $312.01 installment written as $312 instead of $313 still flags as a non-conforming payment.
• Confirm the designation block on each voucher (form number, tax year, or quarter the payment applies to). The designation right ends the day the IRS issues the acceptance letter, so any portfolio-wide redesignation has to happen before that date.
• Track each client's decision-letter status as a four-state field on the OIC register. The day the letter lands, the payment obligation ends, and continuing to bill a client for a voucher after that point is rework that erodes trust.

Accountably's offshore tax delivery teams run this exact cadence inside the casework system already in place. Voucher prep, payee standardization, rounding QA, and decision-letter triage become a repeatable monthly cycle the team owns end to end, so an OIC portfolio does not bottleneck on one reviewer's calendar.

FAQs

Does using Form 656‑PPV stop IRS collections?

It usually pauses new levy actions while the offer is pending, and while you keep up with required filings and payments. Existing liens typically stay in place. If you miss payments or stop filing, the pause can end quickly.

How long does the early review take?

Early screening can take a few weeks. Full evaluation can take longer, especially during peak periods. You can help yourself by sending a complete packet and answering any IRS request on time.

Can I submit the Form 656‑PPV online?

No, the voucher itself is not submitted online. If you pay online, you use the OIC payment path and the OIC number, and you keep the confirmation. If you mail checks, you attach the paper voucher.

Will sending 656‑PPV trigger an audit?

No. The IRS reviews your eligibility and your financials for the OIC. That is different from an income tax audit. If your return has obvious issues, the IRS can audit separately, but sending 656‑PPV is not the trigger.

Do I need a new voucher for every payment?

Yes. Use a separate, numbered voucher for each monthly installment while the offer is pending. If you pay online, you still enter the same information that appears on the voucher so the IRS credits the right case.

Where do I find my OIC number?

Look at the acknowledgment or request letters the IRS sends after it receives your offer. If you do not have a number yet, use your name, SSN, and the tax periods listed on your Form 656, and follow the instructions in your letter.

What happens after my offer is accepted?

You will receive an acceptance letter with specific terms. You must stay current on filing and payment obligations for five years after acceptance. If you default on those future obligations, the IRS can reinstate the liability.
